Abstract

A vehicle seat includes a cushion material and a cover for covering the cushion material. The cover includes a load receiving portion configured to receive a load of a seated occupant. The load receiving portion includes a large thickness portion and a small thickness portion that are located next to each other in a first direction that intersects with a thickness direction of the cover. Each of the large and small thickness portions includes an elastic layer compressive in the thickness direction and a lower cover layer located closer to the cushion material than the elastic layer in the thickness direction. The elastic layer of the small thickness portion is compressed such that the thickness of the small thickness portion is smaller than the thickness of the large thickness portion. The lower cover layer of the large thickness portion is partially cut off to form a cutoff portion.

First claim

What is claimed is:

1. A vehicle seat comprising:
a cushion material; and
a cover adapted to cover the cushion material;

wherein:
the cover includes a load receiving portion configured to receive a load of an occupant seated on the vehicle seat;
the load receiving portion includes a large thickness portion and a small thickness portion that are located next to each other in a first direction that intersects with a thickness direction of the cover;
each of the large thickness portion and the small thickness portion includes an elastic layer which is compressive in the thickness direction and a lower cover layer located closer to the cushion material than the elastic layer in the thickness direction;
the elastic layer of the small thickness portion is compressed such that the thickness of the small thickness portion is smaller than the thickness of the large thickness portion; and
the lower cover layer of the large thickness portion is partially cut off to form a cutoff portion.

2. The vehicle seat according to claim 1 , wherein:
the small thickness portion includes a first extending portion that extends in the first direction where the large thickness portion and the small thickness portion are located next to each other and a second extending portion that extends to intersect with the first extending portion; and
the large thickness portion is located next to the second extending portion to extend along the second extending portion.

3. The vehicle seat according to claim 2 , wherein:
the small thickness portion includes a pair of second extending portions that are spaced apart from each other and include the second extending portion; and
the cutoff portion is formed in the lower cover layer of the large thickness portion positioned to be interposed between the pair of second extending portions.

4. The vehicle seat according to claim 3 , wherein:
the pair of second extending portions is spaced apart from each other in a front to back direction of the vehicle seat; and
each of the pair of second extending portions, the large thickness portion positioned to be interposed between the pair of second extending portions, and the cutoff portion extend in a width direction of the vehicle seat.

5. The vehicle seat according to claim 1 , wherein:
the cover further includes an upper cover layer separated further from the cushion material than the elastic layer in the thickness direction;
the elastic layer is interposed between the lower cover layer and the upper cover layer;
the lower cover layer of the small thickness portion is continuously formed with the lower cover layer of the large thickness portion; and
the upper cover layer of the small thickness portion is continuously formed with the upper cover layer of the large thickness portion.

6. The vehicle seat according to claim 1 , wherein the cutoff portion is a cut formed in the lower cover layer.

7. The vehicle seat according to claim 1 , wherein the cutoff portion is a hole formed in the lower cover layer.

8. The vehicle seat according to claim 1 , wherein the cutoff portion is provided at a central portion of the lower cover layer of the large thickness portion in the first direction where the large thickness portion and the small thickness portion are located next to each other.

9. The vehicle seat according to claim 1 , wherein:
the vehicle seat is a straddle seat on which an occupant can sit straddled; and
the load receiving portion is a portion of the cover on which the buttocks of the occupant seated on the vehicle seat are rested.
