Technical Field

The present invention relates to a vehicle.

Background

Japanese patent application publication (JP- ｃA) No. 2017-148445 (patent document 1) discloses ｃA vehicle in which ｃA wheelchair placing region for placing ｃA wheelchair is formed by turning up and moving ｃA seat cushion of ｃA passenger seat.

There are vehicles having fixed seats in which the face of an occupant seated in the fixed seat faces in the vehicle lateral direction. In such a vehicle, by using the structure of patent document 1, a space for placing a wheelchair is secured while the seat cushion is sprung upward.

Here, in the case where the wheelchair is placed on the floor portion so that the face faces in the vehicle lateral direction, since the entire length of the wheelchair is longer than the vehicle lateral direction length of the seat cushion, the wheelchair restricts the movement of the occupant in the vehicle longitudinal direction.

Also, in the case where the wheelchair is placed on the floor portion so that the face is directed toward the vehicle longitudinal direction, since there is nothing between the wheelchair and the occupant seated in the fixed seat, there is a possibility that the wheel of the wheelchair contacts the occupant seated in the fixed seat. That is, in the structure having the stationary seat fixed to the floor portion such that the face of the seated occupant faces in the vehicle lateral direction, there is room for improvement in seating the occupant in the wheelchair on the vehicle while also taking into consideration the occupant seated in the stationary seat.

Disclosure of Invention

In view of the above circumstances, an object of the present invention is to provide a vehicle in which, in a structure having a stationary seat fixed to a floor portion such that a face of a seated occupant faces in a vehicle lateral direction, the occupant in a wheelchair can be seated on the vehicle while also taking into consideration the occupant seated in the stationary seat.

A vehicle relating to a first aspect of the invention has: a stationary seat fixed to the floor portion such that a face of a seated occupant faces in a vehicle lateral direction; a movable seat having a seat cushion on which an occupant sits, and a support member that supports the seat cushion such that the seat cushion is rotatable toward the fixed seat, the movable seat being arranged at the floor portion at least one of a vehicle longitudinal direction front side or a vehicle longitudinal direction rear side with respect to the fixed seat, and a wheel of a wheelchair being contactable with the seat cushion in the vehicle longitudinal direction; and a fixing member that fixes the wheelchair to the floor portion in a state where the wheel is brought into contact with the movable seat.

In the vehicle relating to the first aspect, the seat cushion rotates toward the fixed seat. Thereby, a space portion in which the wheelchair can be placed is formed at least at one of the front side and the rear side with respect to the vehicle longitudinal direction of the fixed seat. Here, since the wheels of the wheelchair are brought into contact with the seat cushion in the vehicle longitudinal direction, the occupant in the wheelchair is in a state where the face is directed in the vehicle forward direction or the vehicle rearward direction. Also, the wheelchair is fixed to the floor portion by the fixing member in a state where the wheels are brought into contact with the movable seat.

In this vehicle, since the wheelchair is placed on the floor portion so as to face in the vehicle longitudinal direction, the movement of the occupant seated in the fixed seat in the vehicle longitudinal direction is hardly restricted by the wheelchair. Also, in this vehicle, since the movable seat exists between the wheelchair and the occupant seated in the fixed seat, it is difficult for the wheel of the wheelchair to contact the occupant seated in the fixed seat. Namely, the following vehicle was obtained: in the structure having the stationary seat fixed to the floor portion such that the face of the seated occupant faces in the vehicle lateral direction, the occupant in the wheelchair can ride the vehicle while taking into consideration the occupant seated in the stationary seat.

The movable seat of the vehicle relating to the second aspect of the invention is arranged on the vehicle longitudinal direction front side with respect to the fixed seat, and the wheel is brought into contact with the movable seat from the vehicle front side.

In the vehicle relating to the second aspect, the wheelchair is arranged on the front side in the vehicle longitudinal direction. Further, the wheel of the wheelchair is brought into contact with the movable seat from the front side of the vehicle. Thereby, the occupant in the wheelchair is in a state in which the face is directed in the forward direction of the vehicle at the front of the vehicle, and can see the view in the forward direction of the vehicle. Thus, the occupant in the wheelchair can comfortably wear out in the vehicle.

The movable seat of the vehicle relating to the third aspect of the invention includes: a seat back that supports the occupant from a rear surface side; and a connecting member that connects the seat cushion and the seat back such that the seat back is rotatable with respect to the seat cushion with the vehicle longitudinal direction being a rotation axis direction, wherein the supporting member supports the seat cushion such that the seat cushion is rotatable with respect to the floor portion with the vehicle lateral direction being the rotation axis direction.

In the vehicle of the invention relating to the third aspect, the seat cushion is supported by the support member so as to be rotatable with respect to the floor portion with the vehicle lateral direction being the rotational axis direction. Also, the seat back is connected to the seat cushion by a connecting member. Here, since the seat back is rotated with respect to the seat cushion with the vehicle longitudinal direction being the rotation axis direction, the seat back is brought into a folded state and becomes integrated with the seat cushion. Also, since the seat cushion rotates relative to the floor portion with the vehicle lateral direction being the rotational axis direction, the seat cushion and the seat back rotate integrally toward the fixed seat.

Subsequently, the wheels of the wheelchair are brought into contact with the seat cushion in a state where the seat cushion and the seat back have been integrated. In this way, thrust from the wheels of the wheelchair is applied to the integrated seat cushion and seat back. Therefore, the yield strength with respect to the thrust from the wheel of the wheelchair can be increased as compared with a structure in which the thrust from the wheel of the wheelchair is resisted only by the seat cushion.

A cavity portion and a contact member are provided at the seat cushion relating to the fourth aspect of the invention, the contact member being receivable in the cavity portion and being brought into contact with the floor portion in a state of protruding outward from the cavity portion.

In the vehicle relating to the fourth aspect, the contact member that protrudes outward from the cavity portion contacts the contact plate portion. Thereby, the contact member supports the seat cushion in addition to the support member, and thus the support state of the seat cushion can be stabilized. Also, when the seat cushion is rotated toward the fixed seat, the contact member is accommodated in the cavity portion. Thus, the contact member does not contact the wheel of the wheelchair and therefore the contact member does not affect the placement of the wheelchair. That is, the placement of the wheelchair is not affected, and the support state of the seat cushion can be stabilized.

A groove portion into which the wheel is insertable and withdrawable in the vehicle longitudinal direction is formed in the seat cushion of the vehicle relating to the fifth aspect of the invention.

In the vehicle relating to the fifth aspect, the wheel of the wheelchair is caused to enter the gutter portion in the vehicle longitudinal direction. Also, since the wheel is brought into contact with the groove portion, the movement of the wheel in the lateral direction of the vehicle is restricted. This can suppress the positional deviation of the wheelchair in the lateral direction of the vehicle during the traveling of the vehicle.

As described above, the present invention provides a vehicle in which an occupant in a wheelchair can ride in the vehicle while also taking into account the occupant seated in a fixed seat in a structure having the fixed seat fixed to a floor portion such that the face of the seated occupant faces in the vehicle lateral direction.

An arrow "front" (FR) shown appropriately IN the respective drawings indicates a vehicle forward direction (advancing direction) of the passenger vehicle 10, an arrow "UP" (UP) indicates a vehicle upward direction of the passenger vehicle 10, an arrow "inner" (IN) indicates a vehicle lateral direction inner side of the passenger vehicle 10, and an arrow "outer" (OUT) indicates a vehicle lateral direction outer side of the passenger vehicle 10. Hereinafter, when the description is given only by using the longitudinal direction, the vertical direction, and the left-right direction, they refer to the longitudinal direction of the vehicle longitudinal direction, the vertical direction of the vehicle vertical direction, and the left-right direction of the vehicle lateral direction when the face is toward the advancing direction, unless otherwise indicated.

[ Overall Structure ]

The passenger vehicle 10 has as its main parts an inwardly facing seat 22 and a securing structure 40 for securing a wheelchair 30 (see fig. 2). Moreover, the passenger vehicle 10 has a vehicle body 12 and a floor portion 14, as well as a driver seat 16, a plurality of forward facing seats 18, and a rear seat 24 provided at the floor portion 14. The vehicle body 12 is configured to include a left side wall 26 that constitutes a left side portion of the vehicle, and a right side wall 28 that constitutes a right side portion of the vehicle. The left and right side walls 26, 28 are upright in the vehicle vertical direction and extend in the vehicle longitudinal direction. The inlet 13 is formed on the vehicle front side of the left side wall 26. The outlet 15 is formed on the vehicle rear side of the left side wall 26.

The floor portion 14 is formed in a substantially rectangular shape that is long in the vehicle longitudinal direction when viewed from the vehicle vertical direction. The driver's seat 16 is disposed on the front right side of the floor portion 14. The rear seat 24 extends in the vehicle lateral direction on the floor portion 14 at the rear end portion of the floor portion 14. By way of example, five forward facing seats 18 are provided in passenger vehicle 10. The five forward-facing seats 18 are arranged on the floor portion 14 with a space in the vehicle longitudinal direction along the right side wall 28 and between the driver seat 16 and the rear seat 24.

The inward facing seat 22 is an example of a fixed seat, and is fixed to the floor portion 14. The inward facing seat 22 is disposed at a distance L1 in the vehicle longitudinal direction from the front side space portion 17, the front side space portion 17 facing the entrance 13 in the vehicle lateral direction at the floor portion 14. Also, the inward facing seat 22 extends along the left side wall 26 in the vehicle longitudinal direction to the vicinity of the outlet 15. As an example, the inward facing seat 22 is divided into four seats in the vehicle longitudinal direction.

An occupant PA (see fig. 2) seated in the inward facing seat 22 looks at the forward facing seat 18. In other words, the inward facing seat 22 is fixed to the floor portion 14 such that the face of the occupant PA seated in the inward facing seat 22 faces in the vehicle lateral direction. Further, the inward-facing seat 22 has a seat portion 22A on which the occupant PA sits, and a backrest portion 22B that stands upright from the vehicle transverse direction left side end portion of the seat portion 22A and supports the occupant PA.

The space between the front space 17 of the vehicle floor 14 and the inward facing seat 22 is referred to as a wheelchair riding space K. The wheelchair riding space K is of a size such that a wheelchair 30 (see fig. 2) described later can be placed in the wheelchair riding space K in the vehicle longitudinal direction. Specifically, as an example, the dimension (length) of the wheelchair riding space K in the vehicle longitudinal direction is made to be a dimension (length) corresponding to approximately three portions (three seats) of the inward facing seat 22. Also, as an example, the dimension (length) of the wheelchair riding space K in the vehicle lateral direction is made larger than the dimension (length) of the seat portion 22A in the vehicle lateral direction. Also, as an example, the dimension (height) of the wheelchair riding space K in the vehicle vertical direction is made approximately the same as the dimension (length) of the inward facing seat 22 in the vehicle vertical direction.

< wheelchair >

As an example, the wheelchair 30 shown in fig. 2 is configured to include a main body frame 32, front wheels 34 and rear wheels 36 serving as examples of wheels, and a seat member, not shown, on which an occupant PB sits.

The main body frame 32 is configured to include a lower frame 32A and a tilt frame 32B. The lower frames 32A extend in the vehicle longitudinal direction at the vertically lower portion of the wheelchair 30 and at both vehicle transverse direction side ends of the wheelchair 30. A protruding pin 33 (see fig. 8) is provided at a portion of the lower frame 32A, the protruding pin 33 being a solid cylinder and protruding toward the vehicle upper side. The tilt frame 32B extends at an upward tilt from the rear end portion of the lower frame 32A. A handle portion 32C is formed at an upper portion of the tilt frame 32B, the handle portion 32C being a region that is bent in an L-shape when viewed from the vehicle lateral direction. When an assistant, not shown, other than the occupant PB operates the wheelchair 30, the handle portion 32C is gripped by the assistant.

The front wheel 34 is provided at a front lower portion of the main body frame 32 so as to be rotatable with the vehicle lateral direction being the rotational axis direction thereof. The rear wheel 36 is provided at a rear lower portion of the main body frame 32 so as to be rotatable with the vehicle lateral direction being the rotational axis direction thereof. The diameter of the rear wheel 36 is larger than the diameter of the front wheel 34. Note that the length corresponding to the diameter of the rear wheel 36 is L2.

[ Main Structure ]

The fixing structure 40 is described next.

The fixed structure 40 shown in fig. 2 has a front seat 42 and a fixed member 44, and the front seat 42 serves as an example of a movable seat.

< front seat >

As shown in fig. 3, the front side seat 42 is disposed on the floor portion 14 on the vehicle longitudinal direction front side of the inward facing seat 22, as an example. The rear wheel 36 (see fig. 2) can contact the front seat 42 in the vehicle longitudinal direction from the vehicle front side toward the vehicle rear side. Note that the front side seat 42 is arranged spaced apart from the inward-facing seat 22 by a length L3 in the vehicle longitudinal direction so as to be able to be stowed.

As an example, the front seat 42 shown in fig. 4 has a seat cushion 46, a seat back 48, a support member 52, a connecting member 54, and a lock portion 55 (see fig. 6). The illustration of the locking portion 55 is omitted from fig. 4. Note that, in the following description, a state in which the seat cushion 46 and the seat back 48 are deployed so that an occupant PA (see fig. 1) can sit therein is referred to as a deployed state of the front seat 42. Also, a state in which the seat cushion 46 is stowed (folded) so as to be able to contact the rear wheels 36 (the state shown in fig. 2) is referred to as a stowed state of the front side seat 42. The deployed state of the front seat 42 is shown in fig. 4.

(cushion)

As an example, the seat cushion 46 is formed in a substantially rectangular parallelepiped shape, the outer shape of the seat cushion 46 is substantially quadrangular in the deployed state of the front side seat 42 when viewed from the vehicle vertical direction, and the thickness direction of the seat cushion 46 is the vehicle vertical direction. The seat cushion 46 constitutes a seat surface portion of the front seat 42. An occupant PA (see fig. 2) is seated on the seat cushion 46.

Also, as an example, the seat cushion 46 has a peripheral wall portion 56, a bottom wall 59 (see fig. 5), and a cushion portion 58, the peripheral wall portion 56 being shaped as a corner tube and constituting an outer peripheral portion when viewed from the vehicle vertical direction, the bottom wall 59 covering a vehicle vertical direction lower end of the peripheral wall portion 56, the cushion portion 58 being provided inside the peripheral wall portion 56. As an example, the peripheral wall portion 56 and the bottom wall 59 are formed of stainless steel. By way of example, the cushion portion 58 is composed of polyurethane foam and fabric.

The peripheral wall portion 56 has two side walls 56A and two side walls 56B, the two side walls 56A facing each other in the vehicle longitudinal direction and being formed in a plate shape extending in the vehicle lateral direction, and the two side walls 56B facing each other in the vehicle lateral direction and being formed in a plate shape extending in the vehicle longitudinal direction. Through holes, not shown, that are circular and pass through in the vehicle transverse direction are formed in both side walls 56B at regions further to the vehicle rear side than the vehicle longitudinal direction center. Through which a support shaft 86 described later is inserted.

As shown in fig. 6, a through-hole 57A and a through-hole 57B for locking the seat cushion 46 in the expanded state or the collapsed state are formed in a side wall 56B disposed on the vehicle transverse direction inner side. The through holes 57A and 57B are made the same circular shape and have the same diameter. The through-hole 57A and the through-hole 57B are arranged to be offset from each other by 90 ° in the circumferential direction of the through-hole around the through-hole through which the support shaft 86 is inserted (the through-hole 57A and the through-hole 57B are arranged to overlap if rotated by 90 °).

Fig. 5 shows a state in which the seat cushion 46 in the deployed state is viewed from the vehicle vertical direction lower side. As an example, the cavity portion 62, the contact member 64, and the operation portion 69 are provided at the seat cushion 46. Also, a groove portion 65 and a groove portion 66 are formed in the seat cushion 46. In other words, the cavity portion 62 and the contact member 64 are provided at the bottom wall 59. Also, a groove portion 65 and a groove portion 66 are formed in the bottom wall 59.

As an example, the cavity portion 62 is a region that is recessed toward the vehicle upper side at a front side portion of the bottom wall 59 that is closer to the bottom wall 59 than the vehicle longitudinal direction center of the bottom wall 59. As an example, the cavity portion 62 is formed in a rectangular shape that is long in the vehicle lateral direction. Recesses, not shown, that are recessed toward both outer sides in the vehicle transverse direction are formed at the inner walls 62A, the inner walls 62A facing each other in the vehicle transverse direction at a more front side than the vehicle longitudinal direction center of the cavity portion 62.

The contact member 64 is constituted by a plate member having a size that can be accommodated in the cavity portion 62. Specifically, the outer shape of the contact member 64 is made a rectangular shape that is long in the vehicle lateral direction when viewed from the thickness direction. Two shaft portions 67 that are solid cylinders and protrude toward both outer sides in the vehicle lateral direction are formed at both side surfaces in the vehicle lateral direction of the contact member 64. Since the two shaft portions are inserted into the not-shown recesses of the cavity portion 62 so as to be rotatable with the rotational axis direction thereof being the vehicle lateral direction, the contact member 64 rotates relative to the bottom wall 59.

In the state where the contact member 64 is accommodated in the cavity portion 62, a side surface 64A at the vehicle rear side of the contact member 64 is, as an example, a flat surface extending in the vehicle lateral direction. When the contact member 64 rotates about the shaft portion 67, the side surface 64 protrudes further to the outside (vehicle lower side) than the cavity portion 62. Also, the side surface 64A contacts the top surface of the contact plate portion 14 (see fig. 1) in a state of protruding outward from the cavity portion 62.

The operating portion 69 is provided at the seat cushion 46 at a region facing the shaft portion 67 at the vehicle transverse direction inner side. The operation portion 69 is configured to allow rotation of the shaft portion 67 or to suppress rotation of the shaft portion 67 due to operation of a button, not shown. In other words, with a portion of the contact member 64 projecting from the cavity portion 62 toward the vehicle lower side, and with the contact member 64 accommodated within the cavity portion 62, the rotation of the shaft portion 67 is restricted by the operating portion 69. Also, due to an unillustrated button of the operation portion 69 being operated, the rotation of the shaft portion 67 is permitted.

As an example, the groove portion 65 extends in the vehicle longitudinal direction in a region on the more rear side than the vehicle longitudinal direction center and in a region on the more inner side than the vehicle lateral direction center at the bottom wall 59. The groove portion 65 is a region recessed toward the vehicle upper side. The vehicle lateral direction length of the groove portion 65 is longer than the vehicle lateral direction length of the rear wheel 36 (see fig. 2). That is, it is possible for the rear wheel 36 to enter the groove portion 65 and exit (insert and withdraw) from the groove portion 65 in the vehicle longitudinal direction. Also, as an example, the vehicle longitudinal direction length of the groove portion 65 is made approximately one third of the aforementioned length L2 (see fig. 2).

As an example, the groove portion 66 extends in the vehicle longitudinal direction in a region on the more rear side than the vehicle longitudinal direction center and in a region on the more outer side than the vehicle lateral direction center at the bottom wall 59. The groove portion 66 is a region recessed toward the vehicle upper side. The vehicle lateral direction length and the vehicle longitudinal direction length of the groove portion 66 are the same as the length of the groove portion 65. That is, it is possible for the rear wheel 36 to enter the groove portion 66 and exit from the groove portion 66 in the vehicle longitudinal direction.

The length L4 corresponding to the interval between the groove portions 65 and 66 in the vehicle lateral direction is approximately the same as the length corresponding to the interval between the two rear wheels 36 in the vehicle lateral direction. In the stowed state of the front seat 42, the groove portions 65 and 66 can contact the rear wheels 36 in the vehicle longitudinal direction.

(seat back)

As an example, the seatback 48 shown in fig. 4 is formed in a substantially rectangular parallelepiped shape, the outer shape of the seatback 48 is substantially quadrangular in the deployed state of the front seat 42 when viewed from the vehicle lateral direction, and the thickness direction of the seatback 48 is the vehicle lateral direction. The seat back 48 constitutes a backrest portion of the front seat 42. The seat back 48 supports the occupant PA from the rear surface side (see fig. 2).

Also, as an example, the seat back 48 has a peripheral wall portion 72 that is shaped as an angular tube and constitutes an outer peripheral portion when viewed from the vehicle lateral direction, and a cushion portion 74 that is provided inside the peripheral wall portion 72. As an example, the peripheral wall portion 72 is formed of stainless steel. The cushion portion 74 is constituted by polyurethane foam and fabric, as an example.

The peripheral wall portion 72 has two side walls 72A and two side walls 72B, the two side walls 72A facing each other in the vehicle longitudinal direction and being formed in a plate shape extending in the vehicle vertical direction, and the two side walls 72B facing each other in the vehicle vertical direction and being formed in a plate shape extending in the vehicle longitudinal direction. Through holes, not shown, that are respectively circular and pass through in the vehicle longitudinal direction are formed in the two side walls 72A at a region further on the lower side than the vehicle vertical direction center. Through which a later-described connecting rod 94 is inserted.

(supporting Member)

By way of example, the support member 52 shown in fig. 4 has a single bottom plate 82, two side plates 84, and a single support shaft 86. The bottom plate 82 is fixed to the floor portion 14 (see fig. 1) by using screws, not shown, and with the vehicle vertical direction being the plate thickness direction of the bottom plate 82. The outer shape of the floor panel 82 is a rectangular shape that is long in the vehicle lateral direction when viewed from the vehicle vertical direction. The vehicle lateral direction length of the floor panel 82 is longer than the vehicle lateral direction length of the seat cushion 46.

The two side plates 84 stand upright in the vehicle vertical direction at both vehicle transverse direction end portions of the bottom plate 82. The length corresponding to the interval between the two side plates 84 in the vehicle lateral direction is longer than the vehicle lateral direction length of the seat cushion 46. Also, as an example, the outer shapes of the two side plates 84 are isosceles trapezoids when viewed from the vehicle lateral direction. Also, through holes 84A that are circular and pass through in the vehicle transverse direction are formed in the upper portions of the two side plates 84. Through holes 84B that are circular and pass through in the vehicle transverse direction are formed in the two side plates 84 at the lower side of the through holes 84A. The diameter of the through hole 84B is smaller than the diameter of the through hole 84A. The through hole 84B is formed to communicate with one of the through hole 57A and the through hole 57B (see fig. 6) in the vehicle lateral direction when the seat cushion 46 is rotated.

The support shaft 86 is formed in a solid cylindrical shape. The axial direction length of the support shaft 86 is longer than a length corresponding to the interval between the two side plates 84 in the vehicle transverse direction. Also, in the case where the vehicle lateral direction is the axial direction, the support shaft 86 is inserted through the through-holes, not shown, of the two side walls 56B and the through-holes 84A of the two side walls 84. In the state of insertion through, pull-out prevention members, not shown, are provided at both axial direction end portions of the support shaft 86. Thereby, the support shaft 86 is supported by the two side plates 84. Also, the seat cushion 46 is rotatable (pivotable) about the support shaft 86 in the circumferential direction of the support shaft 86. In other words, the support member 52 supports the seat cushion 46 such that the seat cushion 46 is rotatable with respect to the floor portion 14 (see fig. 1) with the vehicle lateral direction being the rotation axis direction. Also, the support member 52 supports the seat cushion 46 such that the seat cushion 46 can rotate toward the seat 22 (see fig. 1) facing inward.

(connecting Member)

By way of example, the connecting member 54 has two side plates 92 and a single connecting rod 94.

As an example, the outer shape of the two side plates 92 is L-shaped when viewed from the vehicle longitudinal direction which is the thickness direction of the two side plates 92. Specifically, the side plate 92 has a horizontal portion 92A extending in the vehicle lateral direction, and a vertical portion 92B extending from a vehicle lateral direction outer side end portion of the horizontal portion 92A toward the vehicle upper side. The two horizontal portions 92A are each fixed to the vehicle transverse direction outer side portions of the two side walls 56A by using screws, not shown. A through hole 92C that is circular and passes through the side plate 92 in the vehicle longitudinal direction is formed in an upper portion of the vertical portion 92B.

The connecting rod 94 is formed in a solid cylinder shape. The axial direction length of the connecting rod 94 is longer than a length corresponding to the interval between the two side plates 92 in the vehicle transverse direction. In the case where the vehicle longitudinal direction is the axial direction of the connecting rod 94, the connecting rod 94 is inserted through the through hole 92C and a through hole, not shown, of the side wall 72A. In this insertion-through state, unshown pull-out prevention members are provided at both axial direction end portions of the connecting rod 94. Thereby, the connecting rod 94 is supported by the two side plates 92. Also, the seat back 48 is rotatable (pivotable) about the connecting rod 94 in the circumferential direction of the connecting rod 94. In other words, the connecting member 54 connects the seat cushion 46 with the seatback 48 such that the seatback 48 is rotatable with respect to the seat cushion 46 with the vehicle longitudinal direction being the rotational axis direction.

(locking part)

As shown in fig. 6, the lock portion 55 is provided at the side plate 84 on the vehicle transverse direction inner side so as to overlap with the through hole 84B in the vehicle transverse direction.

As shown in fig. 7, the lock portion 55 has, as an example, a support post 102, an operating lever 104, a coil spring 108 as an urging member, and a lock pin 109. The support pillar 102 is fixed to the side panel 84 on the vehicle transverse direction inner side, and extends with its axial direction being the vehicle transverse direction. A through hole, not shown, that passes in the vehicle longitudinal direction is formed in the support pillar 102. The operating lever 104 has a link portion 105 and an operating portion 106, the link portion 105 being long in one direction, the operating portion 106 being columnar and provided at one end portion in the length direction of the link portion 105.

A through hole 105A communicating with the through hole of the support pillar 102 is formed in the lengthwise center portion of the link portion 105. Further, the long hole 105B is formed on the opposite side of the link portion 105 from the operating portion 106 side in the longitudinal direction. The central portion of the link portion 105 is connected to the support column 102 by a connecting pin 107 inserted through the through hole 105A and the through hole of the support column 102. In other words, one end portion and the other end portion of the operating lever 104 can rock in the vehicle lateral direction about the connecting pin 107. In the case where the vehicle transverse direction is the direction of elastic deformation of the coil spring 108, the coil spring 108 is interposed between the side plate 84 and the operation portion 106 side region of the link portion 105.

The lock pin 109 has a main body portion 109A shaped as a solid cylinder and an axial direction of the main body portion 109A is the vehicle transverse direction, and a protruding portion 109B shaped as a solid cylinder and protruding from an outer peripheral surface of a vehicle transverse direction inner side end portion of the main body portion 109A toward the radial direction outer side. As an example, the main body portion 109A is inserted through the through hole 57B and the through hole 84B in the stowed state of the front side seat 42. The protrusion 109B is inserted through the long hole 105B. Here, in the case where the operating portion 106 is moved to the vehicle transverse direction outer side, the coil spring 108 is compressed, and the main body portion 109A comes out of the through hole 57B. On the other hand, in the case where the operating portion 106 is moved inward in the vehicle lateral direction, the coil spring 108 is expanded, and the main body portion 109A is inserted through the through hole 57B. Note that, in the deployed state of the front seat 42 (see fig. 4), the main body portion 109A is inserted through the through hole 57A (see fig. 6) and the through hole 84B. In this way, the locking portion 55 locks the front seat 42 with respect to the side plate 84 in the stowed state and in the deployed state.

< fixing Member >

Each of the two fixing members 44 shown in fig. 8 has a band portion 112, a mounting portion 114, and a hook portion 116. As an example, the fixing members 44 are each arranged on one side and the other side in the vehicle lateral direction with respect to the wheelchair 30 in a state of contacting the front seat 42. Note that the belt portion 112 and the hook portion 116 can be stowed on the lower side of the front seat 42 in the deployed state of the front seat 42.

The band portion 112 is formed in the shape of a rectangular plate long in one direction, and is flexible in this one direction. The mounting portion 114 is constituted by a ring member 114A provided at one end of the band portion 112 and a plate-like mounting hardware 114B. The mounting hardware 114B abuts the side plate 84 and is mounted to the floor section 14 by screws, not shown. The position of the ring member 114A can be changed relative to the mounting hardware 114B. As an example, the hook portion 116 is constituted by an S-shaped hook member. A portion of the hook 116 is attached to the other end of the band 112. Also, the hook portion 116 catches the protruding pin 33 of the wheelchair 30.

Here, in a state where the rear wheel 36 is brought into contact with the front seat 42, the band portions 112 of the two fixing members 44 are extended toward the projecting pins 33, and the hook portions 116 are made to catch the projecting pins 33. Thereby, the fixing member 44 fixes the wheelchair 30 to the floor portion 14.

[ Effect and Effect ]

Next, the operation and effect of the fixing structure 40 of the present embodiment will be described. Note that, it is assumed that the wheelchair 30 (see fig. 2) moves together with the occupant PB on the floor portion 14 of the passenger car 10 shown in fig. 1.

At the fixing structure 40 shown in fig. 7, the lock portion 55 is operated with the state of the front side seat 42 changed from the deployed state to the stowed state. Specifically, as the operating portion 106 moves outward in the vehicle lateral direction, the coil spring 108 is compressed, and the main body portion 109A comes out of the through hole 57B. Thereby, the seat cushion 46 becomes rotatable.

As shown in fig. 9, at the fixed structure 40, as the seat back 48 is rotated (pivoted) toward the vehicle transverse direction inner side about the connecting rod 94, the seat back 48 is set in its folded state contacting the seat cushion 46. Note that illustration of the lock portion 55 is omitted from fig. 9.

Next, the seat cushion 46 and the seat back 48 in the folded state (integrated) are rotated (pivoted) toward the vehicle rear side about the support shaft 86. At this time, the contact member 64 is accommodated in the cavity portion 62 as a result of the operation portion 69 (see fig. 5). Subsequently, in a state where the seat cushion 46 stands upright in the vehicle vertical direction, since the main body portion 109A (see fig. 7) is inserted through the through hole 57B (see fig. 7), the seat cushion 46 is locked (retained). In this way, the wheelchair riding space K is formed on the vehicle front side of the front seat 42 in the stowed state. The groove portions 65 and 66 are arranged to face the wheelchair riding space K.

As shown in fig. 10, in the stowed state of the front seat 42, the front seat 42 is arranged to abut the seat 22 inwardly. Subsequently, the wheelchair 30 is moved from the vehicle front side with respect to the front seat 42. At this time, the rear wheel 36 is brought into contact with the groove portions 65 and 66 (see fig. 9) while being inserted therein.

In a state shown in fig. 8 where the rear wheel 36 and the groove portions 65 and 66 (see fig. 9) are in contact with each other, the band portion 112 is stretched, and the hook portion 116 is caused to catch the projecting pin 33. The wheelchair 30 is pushed toward the front seat 42 due to the tension applied to the belt portion 112. In this manner, the wheelchair 30 is fixed relative to the floor portion 14.

As described above, in the fixing member 40, the seat cushion 46 is rotated toward the seat 22 facing inward. Thereby, a wheelchair riding space K (see fig. 9) in which the wheelchair 30 can be placed is formed on the front side of the seat 22 facing inward.

As shown in fig. 2, since the rear wheels 36 are brought into contact with the seat cushion 46 in the vehicle longitudinal direction, the occupant PB is in a state of facing in the vehicle forward direction. Then, the wheelchair 30 is fixed to the floor portion 14 by the fixing member 44 in a state where the rear wheel 36 is brought into contact with the front seat 42. Here, in the passenger car 10, the wheelchair 30 is placed on the floor portion 14 so as to face in the vehicle longitudinal direction. Therefore, the interval in the vehicle transverse direction between the wheelchair 30 and the forward-facing seat 18 (see fig. 1) is wide, compared to the case where the wheelchair 30 is placed with the face toward the vehicle transverse direction. Thus, the wheelchair 30 hardly restricts the movement of the occupant PA in the vehicle longitudinal direction.

Also, in the passenger vehicle 10, the front seat 42 is present between the wheelchair 30 and the occupant PA seated in the inward-facing seat 22. Therefore, the rear wheels 36 hardly contact the occupant PA seated on the front end side of the inward facing seat 22. That is, in the passenger car 10 having the inward facing seat 22 fixed to the floor portion 14 such that the face of the seated occupant PA faces in the vehicle lateral direction, the occupant PB in the wheelchair 30 can be ridden on the passenger car 10 while also taking into account the occupant PA seated in the inward facing seat 22.

At the fixed structure 40, the wheelchair 30 is arranged on the vehicle front side of the inward facing seat 22. Also, the rear wheel 36 is brought into contact with the front seat 42 from the vehicle front side toward the vehicle rear side. Thereby, the occupant PB in the wheelchair 30 is in a state of facing in the vehicle forward direction at the vehicle front portion, and can see the view in the advancing direction of the passenger car 10. Therefore, the occupant PB in the wheelchair 30 can comfortably wear out in the passenger car 10.

Also, at the fixed structure 40, the seat cushion 46 is supported by the support member 52 so as to be rotatable with respect to the floor portion 14 with the vehicle lateral direction being the rotational axis direction. Also, the seat back 48 is connected to the seat cushion 46 by a connecting member 54. Here, since the seat back 48 is rotated with respect to the seat cushion 46 with the vehicle longitudinal direction being the rotational axis direction, the seat back 48 is set in the folded state and is integrated with the seat cushion 46. Also, since the seat cushion 46 rotates with respect to the floor portion 14 with the vehicle lateral direction being the rotational axis direction, the seat cushion 46 rotates integrally with the seat back 48 toward the seat 22 facing inward.

In a state where the seat cushion 46 is integrated with the seatback 48, the rear wheels 36 are brought into contact with the seat cushion 46. In this way, the thrust force from the rear wheels 36 is applied to the seat cushion 46 and the seat back 48 which are integrated. Therefore, the yield strength with respect to the thrust force from the rear wheels 36 can be increased as compared with a structure in which the thrust force from the rear wheels 36 is resisted only by the seat cushion 46.

In addition, in the fixing structure 40 shown in fig. 9, in the case where the front seat 42 is set to the deployed state, the contact member 64 protruding outward from the cavity portion 62 is brought into contact with the floor portion 14. Thereby, the contact member 64 supports the seat cushion 46 in addition to the support member 52, and thus the support state of the seat cushion 46 can be stabilized. Also, when the seat cushion 46 is rotated toward the inward facing seat 22, the contact member 64 is received in the cavity portion 62. Thus, the contact member 64 does not contact the rear wheels 36 (see fig. 2), and thus the contact member 64 does not affect the placement of the wheelchair 30. That is, the placement of the wheelchair 30 is not affected, and the support state of the seat cushion 46 can be stabilized.

Also, in the fixed structure 40, the rear wheel 36 (see fig. 2) is made to enter the groove portions 65 and 66 in the vehicle longitudinal direction. Since the rear wheel 36 is brought into contact with the groove portions 65 and 66, the movement of the rear wheel 36 in the vehicle lateral direction is restricted. Thereby, the positional deviation of the wheelchair 30 (see fig. 2) in the vehicle transverse direction when the passenger vehicle 10 travels can be suppressed.

Also, a locking portion 55 (see fig. 6) that locks the front seat 42 in the folded state (stowed state) and in the deployed state is provided at the fixed structure shown in fig. 2. Thereby, in the stowed state, the front seat 42 is hardly rocked in the vehicle longitudinal direction, and therefore the occupant PA seated on the front end side of the inward-facing seat 22 can be suppressed from feeling uncomfortable.

In addition, at the fixed structure 40, the support member 52 rotatably supports a region further to the vehicle rear side than the vehicle longitudinal direction center of the seat cushion 46. Thereby, the front seat 42 in the stowed state can be set closer to the inward-facing seat 22 than a structure that supports the center of the seat cushion 46 in the vehicle longitudinal direction. Therefore, it is possible to prevent a wasteful space from being formed between the inward facing seat 22 and the front seat 42.

When the occupant PB in the wheelchair 30 is about to leave the passenger car 10, the hook portion 116 is disengaged from the protruding pin 33 (see fig. 8), and the rear wheel 36 is withdrawn toward the vehicle front side from the groove portions 65 and 66 (see fig. 5). Thereby, the wheelchair 30 and the occupant PB can leave the passenger vehicle 10.

Next, in a case where the state of the front seat 42 is set to the deployed state, since the operating portion 106 (see fig. 7) of the locking portion 55 moves to the vehicle transverse direction outer side, the main body portion 109A comes out of the through hole 57B (see fig. 7). Thereby, the seat cushion 46 and the seatback 48 become rotatable. Subsequently, the seat cushion 46 and the seat back 48 are rotated (pivoted) about the support shaft 86 (see fig. 4) toward the vehicle front side. At this time, since the operation portion 69 (see fig. 5) is operated, the contact member 64 (see fig. 5) is caused to protrude from the inside of the cavity portion 62 (see fig. 5) to the outside and to contact the plate portion 14.

With the seat cushion 46 extending in the vehicle longitudinal direction as well as the vehicle lateral direction, the seat cushion 46 is locked (retained) as a result of the main body portion 109A (see fig. 7) being inserted through the through hole 57B (see fig. 7). Subsequently, since the seat back 48 is rotated (pivoted) toward the vehicle upper side about the connecting rod 94 (see fig. 4), the state of the front side seat 42 is set to the deployed state. In this deployed state, another occupant PA can be seated in the front seat 42.

Note that the present invention is not limited to the above-described embodiments.

< modification >

Fig. 11 shows a passenger vehicle 110 serving as an example of a vehicle. The passenger vehicle 110 has an inwardly facing seat 22 and a securing structure 120 for securing the wheelchair 30. Further, passenger car 110 has the following structure: in the foregoing passenger vehicle 10 (see fig. 1), the inward-facing seat 22 is set to the side close to the entrance 13, and the wheelchair riding space K is set to the rear side in the vehicle longitudinal direction (set to the more front side than the exit 15) with respect to the inward-facing seat 22. Note that in the passenger car 110, the structure other than the inward facing seat 22 and the wheelchair riding space K is similar to that of the passenger car 10.

The fixed structure 120 has a rear seat 122 serving as an example of a movable seat, and a fixed member 44. The rear seat 122 is constituted by the same type of members as the front seat 42 (see fig. 2), but differs from the front seat 42 in that each member is constituted so as to straddle the inward-facing seat 22 in symmetry. That is, the rear seat 122 is disposed at the floor portion 14 at the vehicle longitudinal direction rear side with respect to the inward facing seat 22. Also, the folded seat cushion 46 and the seat back 48 are rotated toward the seat 22 side (vehicle front side) facing inward, and are set to the stowed state. The fixing member 44 extends from a region of the support member 52 adjacent to the floor portion 14 toward the vehicle rear side.

The rear wheel 36 of the wheelchair 30 is brought into contact with the rear seat 122 in the stowed state from the vehicle rear side toward the vehicle front side. Subsequently, the wheelchair 30 is fixed to the floor portion 14 by the fixing member 44. The occupant PB seated in the wheelchair 30 is in a state of facing the vehicle rear side. In this way, even in the case where the wheelchair 30 is fixed to the floor portion 14 on the vehicle longitudinal direction rear side of the inward facing seat 22, the occupant PB in the wheelchair 30 can ride in the vehicle while taking into account the occupant PA seated in the inward facing seat 22.

< other modifications >

The passenger car 10 and the passenger car 110 are not limited to the structure in which the outlet 15 is formed at the rear side of the vehicle, and may be a vehicle in which the outlet is formed at the vehicle longitudinal direction center portion of the left side wall 26. Also, the outlet at the central portion may also serve as an inlet. Inlet 13 may also be used as an outlet at passenger vehicle 10 and passenger vehicle 110.

In the case where the inward facing seat 22 is disposed on the right sidewall 28 side, the fixing structure 40 and the fixing structure 120 may be provided on the right sidewall 28 side. Further, there may be a structure as follows: the fixed structure 40 and the fixed structure 120 are provided at the left side wall 26 so as not to hinder the rotation of the seat back 48 and the seat cushion 46, and the connecting member 54 is removed, and only the seat cushion 46 rotates while being supported by the supporting member 52. Also, the seat back 48 may be eliminated, and the occupant PA may use the left side wall 26 as the seat back.

The cavity portion 62 and the contact member 64 are not necessarily provided at the fixed structure 40 and the seat cushion 46 of the fixed structure 120. For example, in the case where the vehicle longitudinal direction center portion of the seat cushion 46 is supported by a support shaft having a large diameter, the support of the seat cushion 46 is possible even if the contact member 64 is not provided. In this configuration, since the seat cushion 46 is locked by the lock portion 55 (rotation of the seat cushion 46 is restricted), the supporting state can be maintained.

The fixing member 44 is not limited to the structure having the band portion 112, the mounting portion 114, and the hook portion 116. For example, the fixing member 44 may have the following structure: the belt portion 112 is made a rod member, the mounting portion 114 is constituted by a hinge portion, and the hook portion 116 is provided at one end of the rod member. In this structure, since the hinge portion rotates, the hook portion 116 becomes movable, and the hook portion 116 is caused to catch the protruding pin 33. The number of the fixing members 44 is not limited to two, and may be one or more than three.

The number of the support members 52 may be single or plural. Also, the region where the support member 52 supports the seat cushion 46 is not limited to the region at the vehicle longitudinal direction rear side of the seat cushion 46, and may be a region near the center in the case where there is room with respect to the wheelchair riding space K where the wheelchair 30 is placed.

The number of the connecting members 54 may be single or plural. Also, the connecting member 54 is not limited to a structure in which the connecting rod 94 serving as the center of rotation is provided at the seat back 48, and may be a structure in which a hinge portion serving as the center of rotation is disposed between the seat cushion 46 and the seat back 48. Alternatively, there may be a structure in which the connecting rod 94 as the center of rotation is provided at the seat cushion 46.

The contact member 64 is not limited to the structure accommodated in the cavity portion 62. That is, if the contact member 64 does not interfere with the placement of the wheelchair 30, there may be a structure as follows: the cavity portion 62 is not provided at the seat cushion 46, and the front seat 42 is set in the stowed state as it is with the contact member 64 protruding from the seat cushion 46. Also, the contact member 64 protruding from the seat cushion 46 as it is may be used as a restricting member that restricts the movement of the rear wheel 36 in the vehicle vertical direction. Also, the number of the contact members 64 is not limited to one, and may be plural. In addition, the shape of the contact member 64 is not limited to the shape of a plate having a flat surface, and may be a shape having a curved surface.

The groove portions 65 and 66 need not be formed in the bottom wall 59 of the seat cushion 46. Also, the groove portion is not limited to a structure recessed from the bottom wall 59 toward the inside of the seat cushion 46, and may be a region formed by protruding from the bottom wall 59 toward the outside of the seat cushion 46.

The inward facing seats 22 are not limited to being divided into four seats, and may be divided into two seats, three seats, or five seats or more. Also, the inward facing seat 22 may be made a bench that is not divided in the vehicle longitudinal direction.

The front side seat 42 or the rear side seat 122 in the stowed state may be used as an armrest member for the occupant PA seated in the inward-facing seat 22.

The size of the wheelchair riding space K is not limited to the size corresponding to about three portions of the inward facing seat 22, and may be set to a size different from three portions.

The respective longitudinal lengths of the groove portion 65 and the groove portion 66 are not limited to (L2)/3, and may be another length.

As the restraining member that restrains the occupant PB of the wheelchair 30, for example, an outer belt having a tongue may be provided on the vehicle inside of the left side wall 26, and a restraining member that holds the tongue in a buckle portion provided adjacent to the seat cushion 46 may also be used.
