Technical Field

The present invention relates to an in-vehicle device, a control method for an in-vehicle device, a non-transitory storage medium storing a program, and a surface temperature adjustment method for a vehicle seat.

Background

A technique of performing air pre-conditioning in a vehicle cabin by remote operation is known (refer to japanese patent laid-open nos. 2007 & 015504, 2013 & 226858, 2013 & 212809, 2013 & 193681681). For example, in the following japanese patent laid-open No. 2007-015504, the following techniques are disclosed: a plurality of air-conditioning zones capable of independently performing air-conditioning control are set in a vehicle cabin, and when air-conditioning control is required by remote operation, only a priority zone of the plurality of air-conditioning zones is subjected to air-conditioning control.

However, in the case of implementing the above-described technique, it is conceivable that: due to the temperature difference between the temperature of the air-conditioning wind and the temperature in the vehicle compartment, the temperature of the air-conditioning wind may change beyond the imagination before the air-conditioning wind reaches the vehicle seat. Therefore, there is room for improvement in that the surface temperature of the vehicle seat when the occupant is seated is a comfortable temperature.

Disclosure of Invention

The invention aims to obtain an in-vehicle device, a control method of the in-vehicle device, a non-transitory storage medium storing a program, and a surface temperature adjusting method of a vehicle seat, which can make the surface temperature of the vehicle seat when an occupant sits on the vehicle seat comfortable.

A first aspect of the present invention provides an in-vehicle apparatus including: an air conditioning unit that performs air conditioning by blowing out air-conditioned air into a vehicle compartment from an air outlet opening toward the vehicle compartment side, and that can perform air pre-conditioning for air-conditioning the vehicle compartment in advance before a passenger takes a vehicle by remote operation; a seat moving section configured to move a vehicle seat, a front surface of a seat back of which is disposed on a side opposite to the air outlet, in a seat front-rear direction; and a control portion configured to control the air conditioning portion so as to perform the air pre-conditioning and to control the seat moving portion so that the vehicle seat is moved to a seat front side, in a case where the remote operation for performing the air pre-conditioning is performed. In the first aspect, the control section may be further configured to: when the remote operation for performing the air pre-conditioning is performed, the seat moving portion is controlled so that the vehicle seat is moved to a seat front side with respect to a position at which an occupant has recently left the vehicle. The "position at which the occupant has recently got off the vehicle" may be regarded as a position at which the vehicle seat is disposed at the time when the occupant has recently got off the vehicle.

According to the above configuration, the air conditioning unit performs air conditioning (air conditioning) by blowing out the conditioned air into the vehicle compartment from the air outlet opening toward the vehicle compartment side, and can perform air pre-conditioning for air-conditioning the vehicle compartment in advance before the occupant gets into the vehicle compartment by remote operation. The seat moving portion has a function of moving a vehicle seat, in which a front surface of a seat back is disposed on a side facing the air outlet, in a seat front-rear direction. Then, when the remote operation for performing the air pre-conditioning is performed, the control portion controls the air conditioning portion so as to perform the air pre-conditioning, and controls the seat moving portion so that the vehicle seat is moved to the seat front side. Thus, the vehicle seat receives the air conditioning wind subjected to the pre-air conditioning in the state where the occupant approaches the air outlet in front of the occupant, and therefore the surface temperature of the vehicle seat when the occupant is seated is close to the temperature subjected to the pre-air conditioning.

In the first aspect, the in-vehicle device may further include a seatback tilting portion configured to tilt the seatback in the seat front-rear direction, and the control portion may be configured to: when the remote operation for performing the air pre-conditioning is performed, the seatback dumping portion is controlled so that the seatback is dumped toward a seat front side.

According to the above configuration, when the remote operation for performing the air pre-conditioning is performed, the seat back is tilted toward the seat front side, and therefore the air-conditioning wind is more effectively blown to the front surface of the seat back.

In the first aspect, the in-vehicle device may further have an intake portion that can intake air on a front side of the seat back into at least an interior of the seat back of the vehicle seat, and the control portion may be configured to: when the remote operation for performing the air pre-conditioning is performed, the suction portion is controlled so that air on a front side of the seat back is sucked into at least an interior of the seat back of the vehicle seat.

According to the above configuration, when the remote operation for performing the air pre-conditioning is performed, the air on the front side of the seat back is sucked into at least the inside of the seat back of the vehicle seat, and therefore the air-conditioning wind is more effectively blown to the surface of the vehicle seat.

In the first aspect, the in-vehicle apparatus may further include a detection section configured to: the control unit may be configured to detect at least one of a case where a door of the vehicle changes from a closed state to an open state and a case where a door lock of the vehicle changes from a locked state to an unlocked state, and: after the remote operation for performing the pre-conditioning of air is performed, and when at least one of a case where the vehicle seat is moved to a front side and a case where the detection unit detects that the door of the vehicle has changed from the closed state to the open state and a case where the door lock of the vehicle has changed from the locked state to the unlocked state, the seat moving unit is controlled so that the vehicle seat is moved to a position that is the same as: the control portion controls the seat moving portion to move the vehicle seat to a position of the vehicle seat before a seat front side when the remote operation for performing the air pre-conditioning is performed.

According to the above configuration, the detection unit detects at least one of a case where the door of the vehicle is changed from the closed state to the open state and a case where the door lock of the vehicle is changed from the locked state to the unlocked state. Then, after the remote operation for performing the air pre-conditioning is performed, and in a case where the vehicle seat is located on the seat front side with respect to the position where the occupant has recently got off the vehicle and the at least one is detected by the detection portion, the vehicle seat is moved in the seat front-rear direction to the same position as the position where the occupant has recently got off the vehicle. Therefore, the occupant is easy to ride.

In the first aspect, the in-vehicle device may further include a seatback tilting portion configured to tilt the seatback in the seat front-rear direction, and the control portion may be configured to: controlling the seat back dumping portion to dump the seat back to a seat front side based on a remote operation different from the remote operation for performing the air pre-conditioning.

In the first aspect, the in-vehicle device may include an intake portion that is capable of taking in air on a front side of the seat back into at least an interior of the seat back of the vehicle seat, and the control portion may be configured to: controlling the suction portion so that air on a front side of the seat back is sucked into at least an interior of the seat back of the vehicle seat, based on a remote operation different from the remote operation for performing the air pre-conditioning.

A second aspect of the invention provides a control method for an in-vehicle apparatus. The vehicle-mounted device includes: an air conditioning unit that performs air conditioning by blowing out air-conditioned air into a vehicle cabin from an air outlet opening toward the vehicle cabin side, and that can perform air pre-conditioning in which the vehicle cabin is air-conditioned in advance before a passenger gets into the vehicle by remote operation; and a seat moving portion configured to move a vehicle seat in a seat front-rear direction, a front surface of a seat back of the vehicle seat being disposed on a side opposite to the air outlet port, the control method including: when the remote operation for performing the air pre-conditioning is performed, the air conditioning portion is controlled so as to perform the air pre-conditioning, and the seat moving portion is controlled so as to move the vehicle seat to a seat front side.

According to the second aspect, the surface temperature of the vehicle seat when the occupant is seated can be made close to the temperature of the pre-air conditioning.

A third aspect of the present invention provides a non-transitory storage medium storing a program. The program is executed by a computer included in an in-vehicle apparatus having: an air conditioning unit that performs air conditioning by blowing out air-conditioned air into a vehicle cabin from an air outlet opening toward the vehicle cabin side, and that can perform air pre-conditioning in which the vehicle cabin is air-conditioned in advance before a passenger gets into the vehicle by remote operation; and a seat moving section that moves a vehicle seat in a seat front-rear direction, a front surface of a seat back of the vehicle seat being disposed on a side opposite to the air outlet, the computer executing the program to cause the computer to execute processing including: when the remote operation for performing the air pre-conditioning is performed, the air conditioning portion is controlled so as to perform the air pre-conditioning, and the seat moving portion is controlled so as to move the vehicle seat to a seat front side.

According to the third aspect, the computer executes the control program, whereby the same control method of the in-vehicle device as that of the second aspect is implemented by the computer, and the surface temperature of the vehicle seat when the occupant is seated can be brought close to the temperature of the pre-air conditioning.

A fourth aspect of the invention provides a surface temperature adjusting method for a vehicle seat. The surface temperature adjustment method is applied to a vehicle having: an air conditioning unit having an air outlet facing the vehicle compartment side; and a vehicle seat, a front surface of a seat back of which is disposed on a side opposite to the air outlet. The surface temperature adjusting method includes: and moving the vehicle seat to a seat front side while performing air pre-conditioning in which the vehicle cabin is air-conditioned in advance by blowing out air-conditioning wind into the vehicle cabin from the air outlet of the air conditioning portion before the occupant gets in the vehicle.

According to the above configuration, the air pre-conditioning for air-conditioning the vehicle interior in advance is performed before the occupant gets into the vehicle, and the vehicle seat is moved to the seat front side from the position where the occupant has recently got off the vehicle, whereby the vehicle seat approaches the air outlet port. Thus, the surface temperature of the vehicle seat when the occupant is seated is close to the temperature of the pre-air conditioning.

In the fourth aspect, the surface temperature adjustment method may further include: before the occupant sits in the vehicle, the seat back is tilted toward the seat front side. According to this configuration, the seat back is tilted toward the seat front side, and therefore the air conditioning wind is more effectively blown to the front surface of the seat back.

In the fourth aspect, the surface temperature adjustment method may further include: the air on the front side of the seat back is sucked into at least the inside of the seat back of the vehicle seat before the occupant sits in the vehicle. Therefore, the air conditioning wind is more effectively blown to at least the surface of the seat back of the vehicle seat.

As described above, according to the aspect of the present invention, there is an excellent effect that the surface temperature of the vehicle seat when the occupant sits on the seat can be set to a comfortable temperature.

Detailed Description

An in-vehicle device, a control method for the in-vehicle device, a control program for the in-vehicle device, and a surface temperature adjustment method for a vehicle seat according to an embodiment of the present invention will be described with reference to fig. 1 to 5D. Fig. 1 is a simplified diagram showing a state in which the in-vehicle device 20 according to the present embodiment is remotely operated, and fig. 2 is a block diagram showing an example of a schematic configuration of the in-vehicle device 20 according to the present embodiment. In fig. 1, arrow FR indicates the vehicle front side, and arrow UP indicates the vehicle upper side.

As shown in fig. 1, the in-vehicle device 20 is mounted on a vehicle (automobile) 10. In the present embodiment, the vehicle 10 is, for example, an engine car having only an engine as a drive source. As shown in fig. 2, the in-vehicle apparatus 20 is configured to include: the air conditioning unit includes a transceiver unit 22, a control unit 24, an air conditioning unit 26, a seat moving unit 28, a seatback tilting unit 30, an intake unit 32, a first detection unit 34, and a second detection unit 36.

The air conditioning unit 26 is provided to perform air conditioning by blowing out air-conditioning wind into the vehicle cabin 12 from the air outlet 14A toward the vehicle cabin 12 side shown in fig. 1, and is capable of performing air pre-conditioning for air-conditioning the vehicle cabin 12 in advance in front of the occupant by a remote operation. As an example, the air outlet 14A is formed in an instrument panel 14 disposed at the front portion of the vehicle compartment 12. In the vehicle compartment 12, a front surface of a seat back 16A of a vehicle seat 16 (a front seat, as an example) is disposed on a side facing the air outlet 14A.

The transceiver section 22 shown in fig. 2 receives a signal of an air pre-conditioning instruction for causing the air conditioning section 26 to perform air pre-conditioning from a portable device 60 held by a user 70 located outside the cabin 12 of the vehicle 10 shown in fig. 1. When receiving the air preconditioning instruction, the transceiver unit 22 shown in fig. 2 transmits a signal indicating that the instruction has been received to the mobile device 60 (see fig. 1).

The seat moving unit 28 is provided to be able to move the vehicle seat 16 shown in fig. 1 in the seat front-rear direction (i.e., seat sliding in the front-rear direction), and includes a lower rail 28A, an upper rail 28B, and a driving unit (not shown, but a motor as an example). The lower rail 28A is provided on the vehicle floor side with the seat front-rear direction as the long dimension direction. The upper rail 28B is attached to a lower surface side of a seat cushion 16B of the vehicle seat 16, and is engaged with the lower rail 28A so as to be movable in the seat front-rear direction. A drive unit (not shown) is mounted on the seat cushion 16B side of the vehicle seat 16, and the upper rail 28B is moved in the seat front-rear direction by operation of the drive unit.

The seatback tilting portion 30 is provided to tilt the seatback 16A of the vehicle seat 16 in the seat front-rear direction (that is, to change the tilting angle of the seatback 16A in a side view of the seat), and includes a hinge (not shown) and a driving portion (not shown, but a motor as an example). The hinge connects a rear end portion side of the seat cushion 16B and a lower end side of the seat back 16A, and is arranged to include a shaft 30X extending in the seat width direction, and supports the seat back 16A such that the seat back 16A can rotate within a predetermined range about the shaft 30X. The drive portion of the seatback tilting portion 30 pivots a portion of the hinge fixed to one side of the seatback 16A.

The intake portion 32 (shown in the form of a block in the drawing) is also referred to as a Seat Ventilation System (SVS), and can intake air on the front side of the seat back 16A into the seat back 16A. The intake portion 32 includes a blower (not shown) disposed inside the vehicle seat 16 (inside the seat back 16A, as an example). The skin of the vehicle seat 16 is made to be ventilated, and a flow path is formed between the inner surface side of the skin of the vehicle seat 16 and the region where the blower is disposed. As a result, the air blower is operated, and air is sucked into the seat back 16A of the vehicle seat 16 from the front side of the seat back 16A.

The first detection unit 34 shown in fig. 2 as a detection unit detects that the door 18 of the vehicle 10 shown in fig. 1 as the own vehicle has changed from the closed state to the open state. As an example, a courtesy switch (see fig. 2) provided at a peripheral edge of a door opening portion where the door 18 is opened and closed can be applied as the first detection portion 34. The first detection unit 34 shown in fig. 2 outputs a signal corresponding to the open/close state of the door 18 (see fig. 1) to the control unit 24.

The second detection unit 36 as a detection unit shown in fig. 2 detects that the door lock 18A (shown in the form of a block in the drawing) of the door 18 of the vehicle 10 as the host vehicle shown in fig. 1 is changed from the locked state to the unlocked state. As an example, a door lock detection switch can be applied as the second detection unit 36 (see fig. 2). When the user 70 who holds the smart key of the vehicle 10 approaches the vehicle 10 and unlocks the door lock 18A using the smart key, the second detection unit 36 (see fig. 2) detects that the door lock 18A is changed from the locked state to the unlocked state before the user 70 arrives at the vehicle 10. The second detection unit 36 shown in fig. 2 outputs a signal corresponding to the state of the door lock 18A (see fig. 1) to the control unit 24.

The control unit 24 is included in a control device 40 as a computer. Fig. 3 shows an example of a schematic configuration of the control device 40 and a configuration part connected to the control device 40 according to the present embodiment. As shown in fig. 3, the control device 40 includes: a CPU (Central Processing Unit) 42, a RAM (Random Access Memory) 44, a ROM (Read Only Memory) 46, an input/output interface (I/O)50, and the transmitter/receiver 22 are communicatively connected to each other via a bus 52.

The CPU42 executes various programs and performs control of each unit (device) connected to the control device 40 and various calculations in accordance with the programs. The ROM46 is a nonvolatile memory, and various programs such as the control program 48 (an example of a control program for the in-vehicle device according to the present invention) and various data are stored in the ROM 46. The RAM44 temporarily stores various data such as positional information when an occupant of the vehicle seat 16 (see fig. 1) has recently got off the vehicle, and is used as a work area of the program. The I/O50 performs communication with external devices. The I/O50 is connected to the air conditioning unit 26, the seat moving unit 28, the seatback tilting unit 30, the suction unit 32, the first detection unit 34, and the second detection unit 36. The control program 48 is read from the ROM46 and developed in the RAM44, and the CPU42 executes the control program 48 developed in the RAM44, whereby the control device 40 functions as the control unit 24 (see fig. 2).

When the remote operation for performing the air pre-conditioning is performed, the control portion 24 shown in fig. 2 controls the air conditioning portion 26 so as to perform the air pre-conditioning, and controls the seat moving portion 28 so that the vehicle seat 16 is moved to the seat front side from the position 16X (both refer to fig. 1) at which the occupant has recently left the vehicle. Further, when the remote operation for performing the air pre-conditioning is performed, the control portion 24 controls the seatback tilting portion 30 so that the seatback 16A (see fig. 1) is tilted toward the seat front side, and controls the suction portion 32 so that the air on the seat front side of the seatback 16A is sucked into the seat back 16A. Then, when the remote operation for performing the air pre-conditioning is performed and the vehicle seat 16 is positioned on the seat front side with respect to the position 16X (see fig. 1) at which the occupant has recently left the vehicle, and when it is detected by the first detection portion 34 that the door 18 (see fig. 1) of the vehicle 10 has changed from the closed state to the open state, or when it is detected by the second detection portion 36 that the door lock 18A (see fig. 1) of the vehicle 10 has changed from the locked state to the unlocked state, the control portion 24 controls the seat moving portion 28 so that the vehicle seat 16 moves in the seat front-rear direction to the same position as the position 16X at which the occupant has recently left the vehicle.

Next, as an operation of the present embodiment, a control process executed by the CPU42 (see fig. 3) in the vehicle 10 in which the in-vehicle device 20 shown in fig. 1 to 3 is mounted will be described with reference to a flowchart shown in fig. 4. As an example, when a remote operation for starting the engine (an engine start request) is performed by the portable device 60 or the like and a remote operation for performing air pre-conditioning (an operation request for air pre-conditioning) is performed by the portable device 60, the control shown in fig. 4 is started. The surface temperature adjustment method of the vehicle seat is also executed by executing the control processing described below.

First, at step 100 of the control process shown in fig. 4, the CPU42 controls the air conditioning unit 26 so as to perform pre-conditioning of air based on a preset pre-conditioning temperature or the like, and at step 102, controls the intake unit 32 so that air on the front side of the seatback 16A (see fig. 1) is taken into the seatback 16A. As a result, the air conditioning unit 26 in the non-operating state shown in fig. 5A operates as shown in fig. 5B to blow out the conditioned air (see arrow W) from the air outlet 14A into the vehicle cabin 12, and the conditioned air is sucked into the inside of the seat back 16A (see arrow f). Therefore, the air conditioning wind blows to the front surface of the seat back 16A more efficiently. The air pre-conditioning may be a cooling operation in a hot period or a heating operation in a cold period.

Further, in step 104 shown in fig. 4, the CPU42 controls the seat moving unit 28 to move the vehicle seat 16 to the seat front side from the position 16X at which the occupant has recently got off the vehicle (see arrow M1 in fig. 5C). Further, in step 106, the CPU42 controls the seatback tilting portion 30 so that the seatback 16A is tilted toward the seat front side. In the present embodiment, step 106 is executed in a state where the vehicle seat 16 is moving in step 104, as an example. As a modification of the present embodiment, the control may be performed such that step 106 is executed after the vehicle seat 16 is moved to the predetermined position and stopped at step 104. In the present embodiment, the vehicle seat 16 is moved to the forefront position (forefront) of the seat movable range, as an example.

Thereby, as shown in fig. 5C, the seat back 16A approaches the air outlet 14A, and therefore, the air-conditioning wind is more effectively blown to the front surface of the seat back 16A. Further, a part of the air conditioning wind blown to the front surface of the seat back 16A can flow to the seat lower side along the front surface of the seat back 16A. This allows the surface temperature of the vehicle seat 16 when the occupant is seated to be efficiently brought close to the temperature of the pre-air conditioning.

Next, at step 108 shown in fig. 4, the CPU42 determines whether or not the first detection unit 34 has detected that the door 18 of the vehicle 10 as the own vehicle has changed from the closed state to the open state. If the determination at step 108 is positive, the routine proceeds to step 112, and if the determination at step 108 is negative, the routine proceeds to step 110. In step 110, the CPU42 determines whether or not the second detection unit 36 has detected that the door lock 18A of the vehicle 10 as the own vehicle has changed from the locked state to the unlocked state. If the determination at step 110 is positive, the process proceeds to step 112, and if the determination at step 110 is negative, the process returns to step 108.

In step 112, the CPU42 controls the seat moving unit 28 to move the vehicle seat 16 in the seat front-rear direction to the same position as the position 16X at which the occupant has recently got off the vehicle (see arrow M2 in fig. 5D). Further, in step 114, the CPU42 controls the seatback tilting portion 30 so that the seatback 16A is returned to the tilted posture when the occupant has recently got off the vehicle. In the present embodiment, step 114 is executed in a state where the vehicle seat 16 is moving at step 112, as an example. As a modification of the present embodiment, the control may be performed such that step 114 is executed after the vehicle seat 16 is moved and stopped at step 112. As shown in fig. 5D, by executing step 112 and step 114, the vehicle seat 16 is returned to the state in which the occupant has recently got off the vehicle, and therefore the occupant can easily get on the vehicle.

Then, at step 116 shown in fig. 4, after the air-conditioning performed by the air-conditioning unit 26 shifts from the air pre-conditioning to the normal air-conditioning (air-conditioning in the occupant riding state), the CPU42 ends the control process shown in fig. 4 (in other words, ends the control program 48).

As described above, in the present embodiment, the surface temperature of the vehicle seat 16 when the occupant sits can be set to a comfortable temperature. As a result, the passenger's comfort during riding can be improved.

In the above-described embodiment, the case where the vehicle seat 16 in which the air outlet 14A shown in fig. 1 and the like is formed in the instrument panel 14 and the seat moving portion 28, the seatback tilting portion 30, and the suction portion 32 controlled by the control portion 24 (see fig. 2) are provided is a front seat has been described, but as a modification of the above-described embodiment, for example, the following configuration may be adopted: the vehicle is an automobile equipped with three rows of seats, and the vehicle seat in which the air outlet is formed in the back surface portion of the seat back of the front seat and the seat moving portion, the seat back tilting portion, and the suction portion 32 controlled by the control portion 24 are provided is a second seat (seat in the second row).

Further, as a modification of the above embodiment, the suction portion may be provided so as to be able to suck air on the front side of the seat back 16A into the inside of the seat back 16A and into the inside of the seat cushion 16B. In this case, the control section 24 may also be configured to: when the remote operation for performing the air pre-conditioning is performed, the suction portion is controlled so that the air on the front side of the seat back 16A is sucked into the inside of the seat back 16A and the inside of the seat cushion 16B.

In the above-described embodiment, the description has been given of the case where the engine vehicle is an example of the vehicle 10, but the vehicle mounted with the in-vehicle device of the present invention may be a hybrid vehicle or an electric vehicle. When the vehicle on which the in-vehicle device of the present invention is mounted is a hybrid vehicle or an electric vehicle, the control process shown in fig. 4 may be started when a remote operation (an operation request for pre-air conditioning) for performing pre-air conditioning is performed by the portable device 60.

As a modification of the above embodiment, one or both of steps 102 and 106 in the flowchart shown in fig. 4 may be omitted. Note that the sequence of steps 102 to 106 may be reversed and executed. For example, the flow may be executed in the order of step 100, step 104, step 106, and step 102, and in this case, step 106 and step 102 may be executed while the vehicle seat 16 is moving in step 104. One or both of step 112 and step 114 may be omitted.

As a modification of the above embodiment, the following procedure may be adopted: step 110 shown in fig. 4 is omitted, and if the determination at step 108 is negative, the vehicle waits until the door 18 of the vehicle 10 changes from the closed state to the open state (that is, step 108 is repeated). As another modification of the above embodiment, the following procedure may be adopted: step 108 shown in fig. 4 is omitted and step 110 is performed after step 106.

The control program 48 shown in fig. 3 may be stored in a storage medium or the like so as to be circulated.

As a modification of the above embodiment, the surface temperature adjusting method for the vehicle seat may be configured to execute the following by an independent operation request from the portable device 60: the air conditioning device is configured to pre-condition air in the vehicle cabin 12 by blowing out air-conditioning air from the air outlet port 14A of the air conditioning portion 26 into the vehicle cabin 12, to move the vehicle seat 16 to the seat front side from the position 16X at which the occupant has recently got off the vehicle, to tilt the seat back 16A to the seat front side, and to suck air on the front side of the seat back 16A into at least the inside of the seat back 16A of the vehicle seat 16. In the above modification, the control unit may be configured to receive the following operation request only when the air pre-conditioning is received: the vehicle seat 16 is moved to the seat front side from a position 16X at which the occupant has recently got off the vehicle, the seat back 16A is tilted to the seat front side, and air on the front side of the seat back 16A is sucked into at least the seat back 16A of the vehicle seat 16. Further, the vehicle 10 is configured to receive the next scheduled riding time, and the control portion 24 may execute the following: the air pre-conditioning is performed in accordance with the received riding time, the vehicle seat 16 is moved from the position 16X at which the occupant has recently got off to the seat front side, the seat back 16A is tilted toward the seat front side, and the air on the front side of the seat back 16A is sucked into at least the seat back 16A of the vehicle seat 16.

The above-described embodiment and the above-described modification examples can be implemented by appropriately combining them.

While one example of the present invention has been described above, the present invention is not limited to the above description, and it goes without saying that various modifications can be made without departing from the scope of the invention.
