The vehicle seat 10 of this embodiment will be explained using FIGS. 1 to 4.

FIG. 1 shows a perspective view of a vehicle seat 10 according to the present embodiment, viewed from the front left side of the seat. In the figure, arrow FR indicates the front side of the seat, arrow UP indicates the upper side of the seat, arrow RH indicates the right side in the seat width direction, and arrow LH indicates the left side in the seat width direction. In addition, in the following description, when front and back, top and bottom, and left and right directions are used unless otherwise specified, they refer to front and back in the seat front and back direction, top and bottom in the seat up and down direction, and left and right in the seat width direction.

As shown in FIG. 1, the vehicle seat 10 includes a seat cushion 12 that supports the buttocks of a seated occupant from below, a seat back 14 that supports the back of the seated occupant from the rear side of the seat, and a head of the seated occupant. and a headrest 16 that supports the seat from the rear side of the seat.

The seat cushion 12 is configured such that a seat cushion pad 20 as a seat pad covered with a skin material 18 is attached to a seat cushion frame (not shown). Further, the seat back 14 is configured such that a seat back pad 24 as a seat pad covered with a skin material 22 is attached to a seat back frame (not shown).

As shown in FIG. 2, the seat cushion pad 20 includes a pad body 26 and a ventilation member 28 attached to the pad body 26.

As shown in FIGS. 3 and 4, the pad body 26 includes a main portion 30 that constitutes a central portion of the pad body 26 in the left-right direction. Further, the pad body 26 includes a pair of left and right side support portions 32 that constitute both sides of the pad body 26 in the left and right direction. The pair of left and right side support parts 32 protrude upward with respect to the main part 30.

The main part 30 of the pad body 26 is formed with a concave ventilation member arrangement recess 34 that is open on the seated passenger side.The shape of the ventilation member arrangement recess 34 when viewed from the seated passenger side (upper side) is rectangular. It has a shape. An area surrounded by a groove 38, which will be described later, at the bottom of the ventilation member arrangement recess 34 serves as a mounting surface 34A on which the ventilation member 28 is mounted. Note that a concave air passage portion 36 for supplying or discharging air passing through the ventilation member 28 is formed in a part of the area of the main portion 30 that corresponds to the mounting surface 34A. The dimension D from the mounting surface 34A to the upper surface 30A of the main portion 30 is set to be approximately the same as the thickness dimension T of the ventilation member 28.

Further, a concave groove 38 is formed at the bottom of the ventilation member arrangement recess 34 on the inner circumferential surface 34B side of the ventilation member arrangement recess 34 and is open toward the seated occupant. This groove portion 38 is formed along the inner circumferential surface 34B of the ventilation member arrangement recess 34. As a result, the shape of the groove portion 38 when viewed from the side of the seated occupant is a rectangular shape surrounding the mounting surface 34A. Further, as shown in FIG. 4, the groove width W of the groove portion 38 is set to a dimension that allows the end portion 28A of the ventilation member 28 to be pushed into it. Here, the groove width W of the groove portion 38 may be set to be slightly larger than or the same as the thickness T of the ventilation member 28. In this case, the end portion 28A of the ventilation member 28 can be easily pushed into the groove portion 38. Further, the groove width W of the groove portion 38 may be set to be slightly smaller than the thickness T of the ventilation member 28. In this case, the end 28A of the ventilation member 28 can be pushed into the groove 38 while expanding the groove 38 with the end 28A of the ventilation member 28.

As shown in FIGS. 2 and 4, the ventilation member 28 is formed in a sheet shape with a predetermined thickness T, and is formed in a rectangular shape when viewed from the seated passenger side. The ventilation member 28 is formed, for example, by weaving thread-like polyester resin. Thereby, the ventilation member 28 has a configuration that allows air to pass through the inside thereof. Here, the dimension A1 in the left-right direction and the dimension A2 in the front-rear direction of the ventilation member 28 are set to correspond to the dimension in the left-right direction and the dimension in the front-rear direction of the ventilation member placement recess 34. In the example shown in FIG. 4, the dimension A1 of the ventilation member 28 in the left-right direction is the same as the dimension of the ventilation member placement recess 34 in the left-right direction. Therefore, when the ventilation member 28 is placed in the ventilation member placement recess 34 and placed along the placement surface 34A, both ends 28A of the ventilation member 28 in the left and right direction are placed inside the ventilation member placement recess 34. It is in contact with the inner peripheral surface 34B.

(Actions and effects of this embodiment)
Next, the operation and effects of this embodiment will be explained.

As shown in FIGS. 1, 2, and 4, in the vehicle seat 10 of the present embodiment described above, air supplied from an air supply device (not shown) can flow along the ventilation member 28. Thereby, it is possible to suppress an increase in humidity at the boundary between the seated occupant and the seat cushion 12.

By the way, due to manufacturing variations in the ventilation member 28, etc., the left-right dimension A1 and the front-back dimension A2 of the ventilation member 28 may differ from the left-right dimension and the front-back dimension of the ventilation member placement recess 34. It may be larger than. In the example schematically shown in FIG. 5, the dimension A1 of the ventilation member 28 in the left-right direction is larger than the dimension of the ventilation member placement recess 34 in the left-right direction. In this case, both ends 28A of the ventilation member 28 in the left and right direction can be pushed into the left and right grooves 38. Here, when both ends 28A in the left and right direction of the ventilation member 28 are pushed into the left and right grooves 38, both ends 28A in the left and right direction of the ventilation member 28 are bent toward the groove 38 side, and the ventilation member 28 is bent toward the groove 38 side. Both end portions 28A of the member 28 in the left and right direction are arranged within the groove portion 38. Thereby, both ends 28A of the ventilation member 28 in the left and right direction can be prevented from protruding from the ventilation member arrangement recess 34 toward the seated occupant. As a result, it is possible to suppress deterioration of the appearance design of the seat cushion 12 and the comfort of the seated occupant.

Although not shown, even if the dimension A2 of the ventilation member 28 in the front and back direction is larger than the dimension of the ventilation member placement recess 34 in the front and rear direction, both ends of the ventilation member 28 in the front and rear direction 28A can be pushed into the front and rear grooves 38. Thereby, it is possible to suppress deterioration of the appearance design of the seat cushion 12 and the comfort of the seated occupant.

In the example schematically shown in FIG. 6, the dimension A1 of the ventilation member 28 in the left-right direction is smaller than the dimension A1 of the ventilation member arrangement recess 34 in the left-right direction. In this case, when the ventilation member 28 is placed in the ventilation member placement recess 34 and placed along the placement surface 34A, both ends 28A in the left and right direction of the ventilation member 28 are placed inside the ventilation member placement recess 34. It is spaced apart from the inner circumferential surface 34B of. That is, a gap 40 is formed between both end portions 28A of the ventilation member 28 in the left-right direction and the inner circumferential surface 34B of the ventilation member placement recess 34.

By the way, even if the dimension A1 in the left-right direction and the dimension A2 in the front-rear direction of the ventilation member 28 are larger than the dimension in the left-right direction and the dimension in the front-rear direction of the ventilation member arrangement recess 34, the above-mentioned The end 28A of the ventilation member 28 can be pushed into the groove 38 as shown in FIG. Therefore, the dimension A1 in the left-right direction and the dimension A2 in the front-rear direction of the ventilation member 28 can be set to be close to the dimension in the left-right direction and the dimension in the front-rear direction of the ventilation member placement recess 34. As a result, the gap 40 between the end 28A of the ventilation member 28 and the inner circumferential surface 34B of the ventilation member arrangement recess 34 becomes smaller, and the displacement of the ventilation member 28 in the ventilation member arrangement recess 34 in the left-right direction and the front-rear direction is reduced. Can be suppressed.

Note that in the example described above, the configuration of the present invention is applied to the seat cushion pad 20, but the configuration of the present invention can also be applied to the seat back pad 24.

Although one embodiment of the present invention has been described above, the present invention is not limited to the above, and can be implemented with various modifications other than the above without departing from the spirit thereof. Of course.
