[0068] As shown in FIG. 14 , a floor tunnel 71 that bulges upward and extends longitudinally is formed in the center of the floor 6 in the left-right direction. The control device 38 may be supported on the upper surface of the front end of the floor tunnel 71. The left and right third temperature adjustment units 37C are disposed in the middle of the instrument panel 15 in the up-down direction. The harness 68 connecting the control device 38 and the left first temperature adjustment unit 37A may pass in front of the left third temperature adjustment unit 37C, extend leftward, and extend to the front end of the front left door 11. The harness 68 connecting the control device 38 and the left first temperature adjustment unit 37A may pass above the left third temperature adjustment unit 37C, extend leftward, and extend to the front end of the front left door 11. In addition, the harness 68 connecting the control device 38 and the left-side first temperature control unit 37A may pass below the left-side third temperature control unit 37C, extend to the left, and extend to the front end of the front-row left door 11.

[0069] As shown in FIG. 15 , the control device 38 may include a front control device 38A provided in the front portion of the vehicle 1 and a rear control device 38B provided in the rear portion of the vehicle 1. The front control device 38A may be provided on the front wall 3. The rear control device 38B may be provided on the rear wall 5. The front control device 38A is connected by a harness 73 to a first temperature adjustment unit 37A, left and right second temperature adjustment units 37B, left and right third temperature adjustment units 37C, and the seat temperature adjustment units 60 of the front left seat 21A and the front right seat 21B, which are provided in the left and right front doors 11. The rear control device 38B is connected by a harness 74 to a first temperature adjustment unit 37A, left and right fourth temperature adjustment units 37D, and the seat temperature adjustment units 60 of the rear left seat 21C and the rear right seat 21D, which are provided in the left and right rear doors 11.

[0070] The temperature adjustment device 22 adjusts its output based on at least one of the configuration of each seat 21 and its position relative to the vehicle 1. The control device 38 adjusts the output of the first to fourth temperature adjustment units 37A to 37D based on at least one of the configuration of each seat 21 and its position relative to the vehicle 1. The control device 38 increases the output of the temperature adjustment units 37 located closer to each seat 21 than the output of the temperature adjustment units 37 located farther from each seat 21. The control device 38 may control the output of each temperature adjustment unit 37 depending on the fore-and-aft position of each seat 21.

[0071] When each seat 21 is positioned rearward of a predetermined rear position, the control device 38 may increase the output of the temperature control unit 37 located at the rear of the multiple temperature control units 37 more than the output of the temperature control unit 37 located at the front.

[0072] For example, the control device 38 acquires the longitudinal position of the front left seat 21A based on a signal from a first seat position sensor that detects the position of the front left seat 21A. The control device 38 may then adjust the output of the front portion 41A, center portion 41B, and rear portion 41C of the first temperature adjustment unit 37A provided in the front left door 11 based on the longitudinal position of the front left seat 21A. For example, when the control device 38 determines that the front left seat 21A is located rearward of a predetermined rear position, the control device 38 may increase the output of the rear portion 41C more than the output of the front portion 41A. Furthermore, when the control device 38 determines that the front left seat 21A is located rearward of the predetermined rear position, the control device 38 may turn off the output of the front portion 41A. This allows temperature adjustment using the portions 41A-41C that are closest to a user seated in the front left seat 21A, thereby reducing energy consumption.

[0073] Similarly, when the control device 38 determines that the front left seat 21A is positioned further forward than a predetermined front position, the control device 38 may increase the output of the front portion 41A more than the output of the rear portion 41C. Furthermore, when the control device 38 determines that the front left seat 21A is positioned further forward than a predetermined front position, the control device 38 may turn off the output of the rear portion 41C.

[0074] The control device 38 may adjust the output of the front portion 47A and the rear portion 47B of the left second temperature adjustment unit 37B provided on the center console 35 based on the fore-and-aft position of the front left seat 21A. For example, when the control device 38 determines that the front left seat 21A is located rearward of a predetermined rear position, the control device 38 may increase the output of the rear portion 47B more than the output of the front portion 47A. Furthermore, when the control device 38 determines that the front left seat 21A is located rearward of the predetermined rear position, the control device 38 may turn off the output of the front portion 47A.

[0075] The control device 38 may adjust the output of each of the temperature adjustment units 37 based on at least one of the angle of the seat back 26 relative to the seat cushion 25 and the angle of the ottoman 32 relative to the seat cushion 25.

[0076] The control device 38 obtains the angle of the seat back 26 relative to the seat cushion 25 as the reclining angle based on a signal from the seat reclining sensor 64. The reclining angle is defined as 0 degrees relative to the vertical, and the value increases as the reclining angle becomes more rearward. When the control device 38 determines that the reclining angle of the front left seat 21A is greater than a predetermined first determination value, it may increase the output of the rear portion 41C more than the output of the front portion 41A. Furthermore, when the control device 38 determines that the reclining angle of the front left seat 21A is greater than the first determination value, it may turn off the output of the front portion 41A. This allows temperature regulation using the portions 41A to 41C closest to a user seated in the front left seat 21A, thereby reducing energy consumption.

[0077] The control device 38 obtains the angle of the ottoman 32 relative to the seat cushion 25 as the ottoman angle based on a signal from the ottoman angle sensor 65. The ottoman angle is defined as an angle of 0 degrees relative to the vertical direction, and the closer the ottoman angle is to the horizontal direction, the larger the value becomes. The control device 38 may turn on the left-side third temperature adjustment unit 37C when it determines that the ottoman angle of the front left seat 21A is greater than a predetermined second determination value. Alternatively, the control device 38 may turn off the left-side third temperature adjustment unit 37C when it determines that the ottoman angle of the front left seat 21A is greater than the predetermined second determination value.

[0078] As shown in Fig. 16, the seat temperature adjusting unit 60 provided on the seat cushion 25 and the seat back 26 may be divided into a plurality of regions 80A, 80B. The seat temperature adjusting unit 60 may be divided into a plurality of regions 80A, 80B in the front-rear direction on the upper surface of the seat cushion 25. The regions 80A and 80B are arranged alternately in the front-rear direction. Furthermore, the seat temperature adjusting unit 60 may be divided into a plurality of regions 80A, 80B in the front-rear direction on the upper surface of the seat cushion 25. The regions 80A and 80B are arranged alternately in the up-down direction.

[0079] The multiple regions 80A are connected to each other and to the control device 38. The multiple regions 80A may be connected to each other in series. The multiple regions 80B are connected to each other and to the control device 38. The multiple regions 80B may be connected to each other in series. The control device 38 can supply power to the multiple regions 80A and the multiple regions 80B independently of each other.

[0080] The control device 38 controls the current values ​​supplied to the multiple regions 80A and the multiple regions 80B based on the ambient temperature TE and the surface temperature TS of the seat 21. The ambient temperature TE may be the surface temperature TS of the seat 21, the temperature of the vehicle interior 2, or the surface temperature of the seat temperature adjustment unit 60. When the ambient temperature TE is higher than a predetermined first temperature threshold T1, the control device 38 may supply a standard current (I0) to the multiple regions 80A and a standard current (I0) to the multiple regions 80B. That is, when the ambient temperature TE is higher than the predetermined first temperature threshold T1, the control device 38 may supply equal currents to the multiple regions 80A and the multiple regions 80B. The first temperature threshold T1 may be, for example, 0°C. When the ambient temperature TE is higher than the predetermined first temperature threshold T1, the control device 38 may supply a standard voltage (V0) to the multiple regions 80A and a standard voltage (V0) to the multiple regions 80B.

[0081] When the ambient temperature TE is lower than the first temperature threshold T1 and the surface temperature TS of the seat 21 is lower than a predetermined second temperature threshold T2, the control device 38 may supply a current twice the standard current (I0) to the plurality of regions 80A and zero the current supplied to the plurality of regions 80B. The second temperature threshold T2 may be set to a temperature higher than the first temperature threshold T1, e.g., 10°C. When the ambient temperature TE is lower than the first temperature threshold T1 and the surface temperature TS of the seat 21 is lower than the predetermined second temperature threshold T2, the control device 38 may supply a voltage twice the standard voltage (V0) to the plurality of regions 80A and zero the voltage supplied to the plurality of regions 80B. According to this embodiment, when the ambient temperature TE and the surface temperature TS of the seat 21 are low, double the current is supplied to the plurality of regions 80A, thereby rapidly increasing the temperature of the plurality of regions 80A. This allows the user to be warmed quickly. Furthermore, since the amount of power consumption remains the same as that during standard operation, the user can be warmed efficiently.

[0082] As shown in FIG. 17 , a plate-shaped table 101 may be provided on the rear surface of the seat back 26 of the front left seat 21A and the front right seat 21B. The table 101 may be rotatably supported on the seat back 26. A fifth temperature adjustment unit 37E is provided on the table 101. The configuration of the fifth temperature adjustment unit 37E is similar to that of the first temperature adjustment unit 37A. The fifth temperature adjustment unit 37E may be provided on at least one of the lower surface and the upper surface of the table 101. The fifth temperature adjustment unit 37E provided on the lower surface of the table 101 adjusts the temperature of the legs of a user seated on the rear left seat 21C and the rear right seat 21D. In addition, a sixth temperature adjustment unit 37F may be provided on the lower part of the rear surface of the seat back 26.

[0083] As shown in FIG. 18, the left-right width of the rear portion of the table 101 may be set to be larger than the left-right width of the front portion. That is, the table 101 may be formed in a trapezoidal shape. The left-right width of the rear portion of the table 101 may be larger than the left-right width of the seat back 26. The shape of the fifth temperature adjustment unit 37E may be set to be the same as the shape of the table 101. The left-right width of the rear portion of the fifth temperature adjustment unit 37E may be larger than the left-right width of the seat back 26. According to this embodiment, the area of ​​the fifth temperature adjustment unit 37E is increased, thereby enabling appropriate temperature adjustment for the user.

[0084] The table 101 may be formed in a rectangular shape when viewed from above. The left-right width of the table 101 may be greater than the left-right width of the seat back 26. According to this embodiment, the area of ​​the fifth temperature adjustment unit 37E is increased, thereby enabling appropriate temperature adjustment for the user.

[0085] The left-right width of the rear portion of table 101 may be set smaller than the left-right width of the front portion. According to this embodiment, table 101 is smaller, so that the space for users seated on rear left seat 21C and rear right seat 21D can be increased.

[0086] As shown in FIG. 19 , a battery 62 may be disposed below the center console 35. The battery 62 may supply power to a drive motor of the vehicle 1.

The second temperature adjustment unit 37B may also be a heat exchanger such as a heat pipe that exchanges heat with the battery 62 and dissipates the heat toward the vehicle interior 2. This embodiment allows the temperature of the user to be adjusted using waste heat from the battery 62, thereby reducing energy consumption. Furthermore, because the battery 62 is disposed below the center console 35, heat generated by the battery 62 can be efficiently transferred to the second temperature adjustment unit 37B provided in the center console 35.

[0087] A heat dissipation section 111 that discharges the air around the battery 62 to the outside may be provided at the bottom of the case 110. The heat dissipation section 111 may be an exhaust port formed in the case 110. The exhaust port may be provided with an exhaust fan to promote exhaust. According to this embodiment, the heat of the battery 62 can be discharged to the outside when heating is not required.

The rear end of the left connecting member 311 is connected to the front end of the second lower bracket 362.

[0115] The lower end of the second upper bracket 363 is fastened to the upper end of the second lower bracket 362 by a fastening member 364. The lower end of the left seatback side member 316 is rotatably supported on the upper part of the second upper bracket 363.

[0116] A rear connecting member 313 extending laterally is inserted and welded through insertion hole 356D of first lower bracket 356 and insertion hole 362A of second lower bracket 362. The right end of rear connecting member 313 may extend further to the right and be connected to rear support part 308 on the right side of the rear right seat.

[0117] 23 and 24, when viewed from above, a portion of the link connecting member 342 is positioned so as not to overlap with the front member 333. This allows an operator to visually check the link connecting member 342 from above the front member 333 during manufacturing of the seat 300, facilitating the work of connecting the link 304 and the link connecting member 342.

[0118] The link connecting member 342 passes below the front right foot 341 and extends laterally. The link connecting member 342 is also sandwiched between the front right foot 341 and the floor 301. This improves the rigidity of the right front support part 307. When a longitudinal load is applied to the seat 300, the link connecting member 342 is prevented from peeling off from the floor 301.

[0119] The first bottom wall portion 342A of the link connecting member 342 abuts against the floor 301. This allows the link connecting member 342 to receive the downward load applied from the link 304 with good stability.

[0120] The link connecting member 342 has a plurality of beads 342E at the boundary between the second bottom wall portion 342C and the second vertical wall portion 342D. The beads 342E improve the rigidity of the link connecting member 342.

[0121] The left front support portion 307 and the left rear support portion 308 are connected by a left connecting member 311. The right front support portion 307 and the right rear support portion 308 are connected by a right connecting member 312. The left and right rear support portions 308 are connected by a rear connecting member 313. The left connecting member 311, the right connecting member 312, and the rear connecting member 313 improve the rigidity of the left and right front support portions 307 and the left and right rear support portions 308. The left connecting member 311, the right connecting member 312, and the rear connecting member 313 are made of pipe material with a closed cross-section structure, and therefore have high rigidity and a simple structure.

[0122] 23, when viewed from above, the left seat cushion side member 332 is disposed so as to be offset in the left-right direction relative to the left connecting member 311. This prevents interference between the left seat cushion side member 332 and the left connecting member 311 when the seat 300 is in the stored form. Furthermore, when viewed from above, the right seat cushion side member 332 is disposed so as to be offset in the left-right direction relative to the right connecting member 312. This prevents interference between the right seat cushion side member 332 and the right connecting member 312 when the seat 300 is in the stored form.

[0123] The distance between the rear portions of the left and right seat cushion side members 332 is set to be shorter than the distance between the front portions. The middle member 334 is joined to the rear portions of the left and right seat cushion side members 332. This allows the distance between the middle members 334 in the left-right direction to be shortened.

[0124] The seat 300 can be transformed from a use configuration shown in FIG. 20 to a storage configuration. In the use configuration, the seat back 302 and the left and right links 304 extend generally vertically, and the seat cushion 303 is positioned above and away from the floor 301. Releasing the locking device 324 allows the seat back 302 to rotate relative to the floor 301. When the seat back 302 rotates forward from the use configuration, the seat cushion 303 moves forward and downward. At this time, the left and right links 304 rotate forward around their lower ends. In the storage configuration, the seat back 302 is folded over the seat cushion 303. [Explanation of symbols]
