Fig. 1 shows a slide seat 10 to which a wiring structure 1 for a slide seat of the present embodiment is applied. The slide seat 10 is disposed in a vehicle interior of the vehicle 100. The slide seat 10 is a rear seat in the vehicle 100, and is, for example, a third seat counted from the front. As shown in fig. 9 and the like, a wiring structure 1 for a slide seat of the present embodiment is a wiring structure for electrically connecting a vehicle body side of a vehicle 100 and a slide seat 10 with a wire harness 2. The wire harness 2 includes, for example, a cylindrical exterior member and a plurality of wires accommodated in the exterior member. The plurality of electric wires include, for example, power supply wires and signal wires.

As shown in fig. 1, the vehicle 100 has a interior 5. The interior member 5 is a member constituting a side wall of a vehicle compartment in the vehicle 100. The interior material 5 is fixed to the inner surface side with respect to the vehicle body panel, for example. The inner material 5 may be a resin molded member. The inner 5 extends in the vehicle front-rear direction X and the vehicle up-down direction H. The interior 5 is supported by the floor member 102, for example.

The slide seat 10 of the present embodiment is configured to be slidable in the vehicle front-rear direction X. The slide seat 10 includes a slider 7, a seat cushion 8, a seat back 9, and a slider 11. The vehicle 100 has a rail 101 guiding the slider 7. The rail 101 is disposed outside the vehicle with respect to the interior 5 and is fixed to the vehicle body. The rail 101 extends in the vehicle front-rear direction X. The slider 7 is slidably supported by the rail 101. That is, the slider 7 is supported by the vehicle body of the vehicle 100 so as to be slidable in the vehicle front-rear direction X. The slider 11 is slidably supported by a rail disposed on the floor member 102.

The slide seat 10 of the present embodiment is configured to be able to bounce the seat cushion 8. The seat cushion 8 is coupled to the slider 7 so as to be rotatable relative to the slider 7. The rotation axis of the seat cushion 8 is along the vehicle front-rear direction X. In fig. 2, the slide seat 10 is shown with the seat cushion 8 sprung up. In the following description, the state in which the seat cushion 8 is bounced up on the slide seat 10 is simply referred to as "the bounced-up state". In the slide seat 10, a state in which the occupant is deployed so as to be able to sit on the seat cushion 8 is simply referred to as a "deployed state". In the deployed state, the seat cushion 8 has a seat surface facing upward in the vehicle vertical direction H, and the seatback 9 stands upright.

When the seat cushion 8 is sprung up, first, the seatback 9 falls down, and the seatback 9 and the seat cushion 8 are integrated. Thereafter, the seat cushion 8 and the seat back 9 stand up toward the interior 5. The slide seat 10 is in the sprung-up state by rotating the seat cushion 8 relative to the slider 7. In the raised state, the back surface of the seat back 9 faces the inner fitting 5. In the raised state, the back of the seat back 9 can also be in contact with the inner fitting 5.

The slider 7 has a slider 70 shown in fig. 3 and an armrest 73 shown in fig. 4. As shown in fig. 3, the slider 70 has a main body 71 and a pair of support portions 72, 72. The main body 71 is slidably supported by the rail 101. The interior member 5 has an opposing portion 5a that faces the rail 101 in the vehicle vertical direction H. The opposing portion 5a is formed with a through hole 50. The through hole 50 penetrates the opposing portion 5a in the plate thickness direction. The through-hole 50 has a width through which the body 71 can be inserted, and extends in the vehicle longitudinal direction X. The main body 71 protrudes upward in the vehicle from the through hole 50.

The support portion 72 protrudes upward from the main body 71. The pair of support portions 72, 72 face each other in the vehicle front-rear direction X. The support portion 72 has a support hole 72 a. The support hole 72a is a recess or a hole formed along the vehicle front-rear direction X. The support hole 72a rotatably supports the rotation shaft of the seat cushion 8. The support hole 72a may be provided with a bearing that supports the rotation shaft of the seat cushion 8.

The inner 5 has a groove-like recess 51 extending in the vehicle front-rear direction X. The concave portion 51 is recessed toward the opposite side to the slider 7 side. The concave portion 51 is disposed corresponding to the movement range of the slider 70. The recess 51 faces the support portion 72 in the vehicle width direction Y. That is, the rotation shaft of the seat cushion 8 faces the recess 51. The recess 51 is provided with an opening 52 for drawing the wire harness 2. The opening 52 connects a space on the vehicle interior side of the interior member 5 and a space on the vehicle exterior side of the interior member 5 in the vehicle width direction Y. The armrest 73 is connected to the slider 70. The armrest 73 covers the slider 70, for example, from the upper side in the vehicle vertical direction H.

As shown in fig. 1 and the like, the winding device 3 is disposed outside the vehicle with respect to the interior material 5. The winding device 3 is disposed at a position facing the recess 51, for example. The winding device 3 is fixed with respect to the body of the vehicle 100. As shown in fig. 5, the winding device 3 includes a main body 30, a cylindrical portion 31, and a lead-out portion 32. The main body 30, the cylindrical portion 31, and the lead-out portion 32 are molded from, for example, an insulating synthetic resin.

The main body 30 is a frame body that accommodates the wire harness 2. The body 30 has a cylindrical shape with both axial ends closed, for example. A winding mechanism for winding the wire harness 2 is disposed inside the main body 30. The winding mechanism includes, for example, a rotating body around which the wire harness 2 is wound and a spring. The winding device 3 can wind the wire harness 2 and draw out the wire harness 2 by the winding mechanism.

The cylindrical portion 31 is formed in a cylindrical shape and extends from the main body 30. The opening 31a of the cylindrical portion 31 is open in the vehicle width direction Y. The wire harness 2 is led out from the inside of the main body 30 through the cylindrical portion 31. The winding device 3 is disposed such that the opening 31a faces the opening 52 of the interior material 5. Therefore, the wire harness 2 drawn out from the opening 31a is inserted through the opening 52 along the vehicle width direction Y. The lead-out portion 32 is an outlet portion for leading out the electric wire on the vehicle body side. The electric wires on the vehicle body side are electrically connected to the wire harness 2 inside the main body 30. The electric wires on the vehicle body side are led out from the lead-out portion 32 and connected to a power supply and a control device.

As shown in fig. 6, the holding member 4 is disposed on the slider 7. The holding member 4 is a member that holds the wire harness 2 and moves in the vehicle front-rear direction X together with the slider 7. The holding member 4 of the present embodiment is fixed to the armrest 73. A part of the holding member 4 protrudes from the side surface 73a of the armrest 73 in the vehicle width direction Y. The wire harness 2 is inserted into the internal space of the armrest 73 via the holding member 4, and is held by the holding member 4.

As shown in fig. 7 and 8, the holding member 4 has a main body 40 and a cover 41. The main body 40 and the cover 41 are molded from, for example, an insulating synthetic resin. As shown in fig. 8, the body 40 has a bottom wall 42, a first side wall 43 and a second side wall 44. The bottom wall 42, the first side wall 43, and the second side wall 44 are formed in one body. The passage 45 of the wire harness 2 is formed by the bottom wall 42, the first side wall 43, and the second side wall 44. The bottom wall 42 is a wall portion that supports the wire harness 2 from below.

The first side wall 43 and the second side wall 44 stand from the edge of the bottom wall 42 and face each other in the vehicle front-rear direction X. The first side wall 43 has a linear portion 43a and a curved portion 43 b. The linear portion 43a extends linearly in the vehicle width direction Y. The base end 43c of the curved portion 43b is connected to the linear portion 43 a. The curved portion 43b is curved so as to be distant from the second side wall 44 from the base end 43c toward the tip end 43d of the curved portion 43 b.

The second side wall 44 has a straight portion 44a and a curved portion 44 b. The straight portion 44a extends linearly in the vehicle width direction Y. The linear portion 44a is opposed to the linear portion 43a of the first side wall 43 and is parallel to the linear portion 43 a. The base end 44c of the curved portion 44b is connected to the linear portion 44 a. The curved portion 44b is curved so as to be distant from the first side wall 43 from the base end 44c toward the tip end 44d of the curved portion 44 b.

In this way, the first and second side walls 43 and 44 are tapered in shape such that the distance between the bent portions 43b and 44b increases as the distance increases toward the distal ends 43d and 44d of the bent portions 43b and 44 b. Therefore, the width of the tunnel 45 is enlarged toward the one end 45a in the vehicle width direction Y.

The cover 41 is a member that engages with the body 40 and covers the duct 45 from above. The cover 41 has a covering portion 46 and an engaging portion 47. The covering portion 46 and the engaging portion 47 are formed integrally. The covering portion 46 is a portion that covers the passage 45 from above. The covering portion 46 has a rectangular portion 46a and a tapered portion 46 b. The rectangular portion 46a is substantially rectangular in shape in plan view. The rectangular portion 46a is formed to cover a portion from the linear portion 43a of the first side wall 43 to the linear portion 44a of the second side wall 44.

The tapered portion 46b in plan view has a tapered shape that widens as it moves away from the rectangular portion 46a in the vehicle width direction Y. The tapered portion 46b covers a portion from the bent portion 43b of the first side wall 43 to the bent portion 44b of the second side wall. The engaging portion 47 engages with the main body 40, and fixes the cover 41 to the main body 40. The cover 41 has a holding portion 49 that holds the wire harness 2. The holding portion 49 protrudes from the covering portion 46 in the vehicle width direction Y.

The holding member 4 has a cylindrical portion 48 formed by the main body 40 and the cover 41. As shown in fig. 7, the width W1 of the cylindrical portion 48 in the vehicle front-rear direction X increases as the opening 48a is opened along the vehicle width direction Y. The wire harness 2 is inserted into the cylindrical portion 48 and held by the holding member 4. The wire harness 2 is fixed to the holding portion 49 by a belt or a band member, for example. That is, the holding portion 49 holds the wire harness 2 via a belt or a belt member. The wire harness 2 may be held by being sandwiched between the bottom wall 42 of the main body 40 and the rectangular portion 46a of the cover 41. In this case, at least one of the bottom wall 42 and the cover 41 may have a protrusion or a rib that presses the wire harness 2.

The holding member 4 is disposed so that the opening 48a faces the recess 51 of the interior material 5. That is, the cylindrical portion 48 is arranged such that the width W1 in the vehicle front-rear direction X is enlarged as approaching the interior 5 along the vehicle width direction Y. The cylindrical portion 48 has a curved shape that does not generate excessive bending stress in the wire harness 2.

Fig. 9 to 11 show the slide seat 10 and the wire harness 2 in the deployed state. The position of the slide seat 10 shown in fig. 9 and the like is the rearmost position in the vehicle front-rear direction X in the movable range. In the following description, the position of the slide seat 10 is simply referred to as the "rear end position" at the rearmost position of the movable range, and the "front end position" at the foremost position of the movable range. At the rear end position, as shown in fig. 10, the holding member 4 faces the opening 52 in the vehicle width direction Y. That is, the opening 52 is positioned coaxially with the cylindrical portion 48 of the holding member 4 in the vehicle width direction Y. The tip 48b of the holding member 4 is located on the same surface as the wall surface 5b of the fitting 5. Therefore, the holding member 4 can cover and conceal the wire harness 2 from the occupant, and can make the wire harness 2 inconspicuous.

As shown in fig. 9 to 11, the harness 2 drawn out from the winding device 3 is inserted through the interior 5 toward the vehicle interior. As shown in fig. 9, the inner 5 has a cylindrical portion 53 protruding in the vehicle width direction Y. The cylindrical portion 53 protrudes toward the cylindrical portion 31 of the winding device 3. The opening 52 is provided at the distal end of the cylindrical portion 53. The shape of the cylindrical portion 53 in plan view is a tapered shape in which the width in the vehicle longitudinal direction X decreases as the cylindrical portion 31 is directed along the vehicle width direction Y.

As shown in fig. 10, the wire harness 2 is drawn out from the opening 52 toward the vehicle interior through the recess 51. The wire harness 2 penetrating the interior 5 is inserted into the cylindrical portion 48 of the holding member 4 and is further arranged in a space inside the armrest 73. As shown in fig. 9, the distal end of the wire harness 2 is fixed to a fixing portion 80 of the seat cushion 8. Each of the wires included in the wire harness 2 is connected to a device disposed in the slide seat 10. The end of each wire may also be connected to a connector. In this case, each wire is connected to the device of the slide seat 10 via a connector.

As shown in fig. 9, the wiring path of the wire harness 2 in the slide seat 10 is curved. In more detail, the wire harness 2 has a first portion 21, a second portion 22, and a bent portion 23. The first portion 21 is a portion extending in the vehicle width direction Y from the retaining member 4 toward the seat cushion 8. The second portion 22 is a portion that extends in the vehicle front-rear direction X and is connected to a device on the seat side. The bend 23 connects the first portion 21 and the second portion 22.

The holding member 4 holds the first portion 21 such that the first portion 21 extends in the vehicle width direction Y. As shown in fig. 11, the first portion 21 of the present embodiment extends in parallel with the vehicle width direction Y. The fixing portion 80 holds the second portion 22 such that the second portion 22 extends in the vehicle front-rear direction X. The fixing portion 80 is disposed at the vehicle front side with respect to the first portion 21, for example. In this case, the second portion 22 extends from the bent portion 23 toward the vehicle front. The second portion 22 of the present embodiment extends parallel to the vehicle front-rear direction X.

As shown in fig. 9, when the slide seat 10 is in the deployed state, the shape of the curved portion 23 in plan view is a substantially arc shape. The shape of the bent portion 23 is determined so as not to generate excessive bending stress to each electric wire of the wire harness 2.

The slide seat 10 is shown in a front position in fig. 12. When the slide seat 10 slides forward in the vehicle longitudinal direction X, the holding member 4 moves forward together with the armrest 73. The holding member 4 moves forward while holding the wire harness 2, and draws out the wire harness 2 from the winding device 3. The drawn wire harness 2 extends in the vehicle front-rear direction X inside the recess 51 of the inner 5. Therefore, the drawn wire harness 2 is difficult to see from the occupant, and the wire harness 2 is less likely to interfere with the armrest 73 or the like. When the slide seat 10 is slid rearward, the winding device 3 winds the excess length of the wire harness 2.

Fig. 13 and 14 show the slide seat 10 and the wire harness 2 in a sprung state. The slide seat 10 of the present embodiment is configured to be able to be bounced at the rear end position. As shown in fig. 13, in the sprung state, the fixed portion 80 of the seat cushion 8 is positioned above the first portion 21 in the vehicle vertical direction H. That is, the seat cushion 8 rotates relative to the slider 70 so that the fixed portion 80 moves upward relative to the first portion 21.

When the seat cushion 8 is bounced up, the fixing portion 80 moves upward while bending the first portion 21 of the wire harness 2. As a result, the second bend 24 is formed in the first portion 21. That is, in the sprung state, the second bent portion 24 is formed in the wire harness 2 in addition to the bent portion 23. The wiring structure 1 for a slide seat is preferably configured to be less likely to generate axial stress on the wire harness 2 when it is sprung up. For example, the rotation mechanism for rotating the seat cushion 8 is preferably configured such that tensile stress is less likely to be generated in the first portion 21 when the seat cushion 8 rotates. For example, at least one of the armrest 73 and the seat cushion 8 may have a space portion that allows bending deformation of the wire harness 2. For example, a space portion may be provided around the portion where the second bent portion 24 is formed so as not to restrain the wire harness 2.

The wiring structure 1 for a slide seat described above enables the wire harness 2 to follow the movement of the slide seat 10 in the vehicle front-rear direction X. Further, the wiring structure 1 for a slide seat can make the wire harness 2 follow the bounce of the seat cushion 8. Thus, the wiring structure 1 for a slide seat can make the wire harness 2 appropriately follow the slide seat 10 with the pop-up mechanism.

Further, by providing the wire harness 2 with the bent portion 23, the bending load on each wire of the wire harness 2 can be reduced. By providing the wire harness 2 with the bent portion 23, the twist of the wire harness made up of a plurality of wires is allowed when the second bent portion 24 is formed. As a result, the bending load of each electric wire is reduced as compared with the case where the wire harness 2 does not have the bent portion 23.

As described above, the wiring structure 1 for a slide seat according to the present embodiment includes the wire harness 2, the winding device 3, and the holding member 4. The winding device 3 is disposed on the vehicle exterior side with respect to an interior member 5 constituting a side wall of the vehicle interior. The winding device 3 is configured to be capable of winding the wire harness 2 and extracting the wire harness 2. The holding member 4 is disposed on a slider 7 positioned on the vehicle interior side with respect to the interior material 5. The holding member 4 holds the wire harness 2 drawn out from the winding device 3 and inserted through the fitting 5.

The slider 7 is supported by the vehicle body so as to be slidable in the vehicle front-rear direction X along the interior 5. The slider 7 supports the seat cushion 8 so that the seat cushion 8 can be raised toward the interior 5. The holding member 4 slides in the vehicle front-rear direction X along the interior 5 together with the slider 7. The wire harness 2 is routed from the holding member 4 to the seat cushion 8, and is fixed to the seat cushion 8. According to the wiring structure 1 for a slide seat of the present embodiment, the wire harness 2 is held by the holding member 4 and is fixed to the seat cushion 8. This enables the wire harness 2 to follow the movement of the slide seat 10 in the vehicle longitudinal direction X, and enables the wire harness 2 to follow the bounce of the seat cushion 8.

The wire harness 2 of the present embodiment has a first portion 21, a second portion 22, and a bent portion 23. The first portion 21 is a portion extending in the vehicle width direction Y from the retaining member 4 toward the seat cushion 8. The second portion 22 is a portion that extends in the vehicle front-rear direction X and is fixed to the seat cushion 8. The bent portion 23 is a portion connecting the first portion 21 and the second portion 22. By providing the wire harness 2 with the bent portion 23, when the first portion 21 is bent by the bounce of the seat cushion 8, the bending load acting on the wires of the wire harness 2 is reduced.

The seat cushion 8 of the present embodiment bounces up while folding the first portion 21. The wire harness 2 has a bent portion 23 so as to allow twisting of the wire harness in the wire harness 2 when the first portion 21 is bent. This reduces the bending load of each wire.

The holding member 4 of the present embodiment has a cylindrical portion 48. The cylindrical portion 48 is a portion that is open toward the interior member 5 and through which the harness 2 is inserted. The cylindrical portion 48 has a tapered shape that expands the width W1 in the vehicle longitudinal direction X as it approaches the interior 5 along the vehicle width direction Y. Therefore, when the cylindrical portion 48 moves in the vehicle front-rear direction X in accordance with the movement of the slide seat 10, the bending load acting on the wire harness 2 is reduced.

The interior material 5 of the present embodiment has a concave portion 51 that is concave toward the opposite side to the slider 7 side. The recess 51 extends in the vehicle front-rear direction X. The wire harness 2 is inserted through the fitting 5 in the recess 51. The holding member 4 is disposed at a position of the slider 7 facing the recess 51. According to this configuration, at least a part of the wire harness 2 can be extended in the recess 51, and interference between the wire harness 2 and the slider 7 and the like can be suppressed.

The recess 51 of the present embodiment is provided with an opening 52. The opening 52 communicates a space outside the interior member 5 with a space inside the interior member 5. The wire harness 2 is inserted through the opening 52, and extends from the opening 52 to a position facing the holding member 4 inside the recess 51 along the vehicle longitudinal direction X. With this configuration, interference of the wire harness 2 with the slider 7 and the like can be more reliably suppressed. In addition, since the wire harness 2 is hidden by the recess 51, the design is improved.

[ modification of embodiment ]

A modified example of the embodiment will be described. A part of the holding member 4 may enter the recess 51 of the interior member 5. For example, the distal end 48b of the cylindrical portion 48 may be located inside the recess 51. With this structure, the wire harness 2 is not easily visible to the occupant. The shape and arrangement of the holding member 4 are not limited to those exemplified in the embodiments.

The fitting 5 may not have the recess 51. In this case, the wire harness 2 extends along the vehicle front-rear direction X in a gap between the wall surface of the inner 5 and the armrest 73.

The wiring path of the wire harness 2 in the slide seat 10 is not limited to the wiring path illustrated in the embodiment. For example, the second portion 22 may extend from the bent portion 23 toward the vehicle rear.

The contents disclosed in the above-described embodiment and modification can be implemented in appropriate combinations.
