It is located on the inner side of the seat than any of the outer ends in the seat outer direction. As a result, the laterally outer end of the grip portion 49 is positioned further outside the seat than the laterally outer end of the cushion-side air conditioner 71 . Therefore, the seated person can easily perform operation input to the grip portion 49 without being obstructed by the cushion-side air conditioner 71 inside the vehicle.

As shown in FIG. 5 , the cushion-side air conditioner 71 (vehicle-exterior air conditioner 71B) is located forward of the front end of the deployment area C of the side airbag 37 . As a result, the vehicle-exterior cushion-side air conditioner 71 is positioned outside the deployment area of the side airbag 37 . As a result, it is possible to prevent the side airbag 37 from being hindered from being deployed by the cushion-side air conditioner 71 on the outside of the vehicle.

As shown in FIG. 1 , the rear edge of the cushion-side air conditioner 71 (vehicle-exterior air conditioner 71B) is located in front of the deployment area A of the door airbag 8 . As a result, the cushion-side air conditioner 71 is positioned outside the deployment area A of the door airbag 8 . Therefore, it is possible to prevent the deployment of the door airbag 8 from being hindered by the cushion-side air conditioner 71 on the outside of the vehicle. In addition, the cushion-side air conditioner 71 inside the vehicle is positioned outside the movable range B of the lid 9B. Accordingly, it is possible to prevent the movement of the lid body 9B from being hindered by the cushion-side air conditioner 71 inside the vehicle.

Next, the vehicle seat 3 according to this embodiment and the effects of the vehicle seat 3 will be described. The vehicle seat 3 is provided with a cushion-side air conditioner 71 for adjusting the temperature of the legs of the seated person. As shown in FIG. 5, the cushion-side air conditioner 71 inside the vehicle is coupled to the seat cushion 11 outside the movable range D of the buckle 51B. Accordingly, it is possible to prevent the movement of the buckle 51B from being hindered by the cushion-side air conditioner 71 inside the vehicle.

As shown in FIG. 4, the vehicle interior air conditioner 71A (the vehicle interior cushion side air conditioner 71) is arranged at a position overlapping the range of motion D of the buckle 51B in a front view. As a result, the width of the vehicle seat 3 in the left-right direction can be made smaller than when the vehicle interior air conditioner 71A does not overlap the range of motion D in front view. Therefore, the vehicle seat 3 can be downsized.

As shown in FIG. 5, the vehicle interior air conditioner 71A (the vehicle interior cushion side air conditioner 71) is arranged outside the movement area E of the seat belt tongue 55 engaged with the buckle 51B. This prevents the movement of the seat belt tongue 55 from being hindered.

As shown in FIG. 4 , the cushion-side air conditioners 71 (vehicle interior air conditioner 71A and vehicle exterior air conditioner 71B) are received in cutouts 83 provided in the pad member 23 of the seat cushion 11, respectively. As a result, the width of the vehicle seat 3 in the left-right direction can be reduced and the size of the vehicle seat 3 can be reduced as compared with the case where the notch 83 is not provided in the pad member 23 . In this embodiment, a gap 85 is provided between the seat cushion 11 and the cushion-side air conditioner 71 by providing the notch 83 in the pad member 23 . Therefore, the cushion-side air conditioner 71 and the pad member 23 do not come into contact with each other, and heat can be prevented from being transferred from the cushion-side air conditioner 71 to the pad member 23 .

As shown in FIG. 6, the heat source 107A of the back side air conditioner 73 is located behind the pillar guide 31D. Therefore, when a rearward load is applied to the seated person, the pillar guide 31D and the pillar 15A hinder the rearward movement of the seated person's neck and prevent the seated person's neck from approaching the heat source 107A.

The control device 81 controls driving of the seat air conditioner 63 based on the temperature in the vehicle interior 2 obtained by the temperature sensor 67 . Accordingly, the vehicle seat 3 can be air-conditioned based on the temperature inside the vehicle compartment 2 where the person sitting on the vehicle seat 3 is. Therefore, the driving of the seat air conditioner 63 can be controlled so as to match the sensible temperature of the seated person.

When the temperature in the passenger compartment 2 obtained by the temperature sensor 67 is equal to or higher than the upper limit threshold, the control device 81 drives the cushion-side air conditioner 71 to apply cool air to the legs of the seated person, thereby cooling the legs of the seated person. Cool the part. At this time, the controller 81 controls the heat source 97A of the vehicle exterior air conditioner 71B so that the air from the blower 93 is cooled more than the air 97A of the vehicle interior air conditioner 71A. As a result, the legs of the seated person are cooled more from the outside of the vehicle than from the inside of the vehicle.

When the temperature in the passenger compartment 2 obtained by the temperature sensor 67 is equal to or lower than the lower limit threshold, the control device 81 drives the cushion-side air conditioner 71 to apply warm air to the legs of the seated person. Warm up your legs. At this time, the control device 81 controls the air from the blowers 93, 103, 113 so that the air from the blowers 93, 103, 113 is warmer than the air 97A of the vehicle-inside air conditioner 71A. As a result, the legs of the seated person are warmed more from the outside of the vehicle than from the inside of the vehicle.

A seated occupant is likely to be affected by the outside temperature on the outside of the vehicle. When the temperature in the passenger compartment 2 is higher than the upper limit threshold and the seat occupant can feel hot, the legs of the seat occupant are cooled more from the outside of the vehicle, the temperature in the passenger compartment 2 is lower than the lower limit threshold, and the seat occupant When the vehicle can feel cold, the occupant's legs are warmed more from the outside of the vehicle. Therefore, the outside of the leg of the seated occupant, which is susceptible to the outside air temperature, can be cooled or heated more than the inside of the leg, so that the influence of the outside air temperature can be reduced.

A seat occupant is more susceptible to ambient temperature in the legs (ie, downward). The control device 81 sets the output of the vehicle exterior air conditioner 71B to be greater than the output of the back side air conditioner 73 and the output of the head side air conditioner 75 . As a result, when the temperature in the passenger compartment 2 is higher than the upper limit threshold and the seated person feels hot, the outside of the seated person's legs are cooled more than the seated person's neck and head. Further, when the temperature in the vehicle interior 2 is lower than the lower limit threshold and the occupant feels cold, the outside of the occupant's legs are warmed more than the neck and head of the occupant. Therefore, the outer side of the seated person's legs, which are susceptible to the outside air temperature, can be cooled or heated more than the neck and head, so that the influence of the outside air temperature can be reduced.

<<Second Embodiment>>
