## Abstract

In a vehicle seat having sound generation source disposed between a seat frame and a cover member covering part of the seat frame from a side, a plate-shaped interposing part disposed between the seat frame and the sound generation source while opposing the seat frame is housed within the cover member, and a plurality of through holes are bored in the plate-shaped interposing part. Accordingly, a resonance space that is efficient and has a small size can be obtained within the cover member.

## Claims

### Claim 1

A vehicle seat, comprising:
a seat frame;
a sound generation source that is disposed on an outside of the seat frame;
a cover member that covers at least a part of the seat frame to cover the sound generation source; and
an intermediate member that is disposed between the sound generation source and the cover member,
wherein the intermediate member includes:
a plate-shaped interposing part that has a plate shape, faces the sound generation source, is disposed along a vertical direction, and forms a first space between the cover member and the plate-shaped interposing part; and
a side wall part that extends from an edge of the plate-shaped interposing part toward the sound generation source in a horizontal direction, forms a second space between the cover member and the side wall part, and is provided with a through hole, wherein the through hole is formed at a position facing the sound generation source in the side wall part and leads to the second space, and
wherein
the seat frame comprises a side frame that supports the sound generation source;
the side wall part includes an upper wall portion that is disposed above the sound generation source; and
the intermediate member includes a fold-back part that is folded back from an end part of the upper wall portion and extends toward a side going away from the sound generation source.

### Claim 2 (depends on 1)

The vehicle seat according to claim 1, wherein
the side wall part includes a lower wall portion that is disposed below the sound generation source, and
a horizontal length of the upper wall portion is greater than a horizontal length of the lower wall portion.

### Claim 3 (depends on 1)

The vehicle seat according to claim 1, wherein the side wall part includes a lower wall portion that is disposed below the sound generation source, and
an end part of the upper wall portion is located at a position farther from the plate-shaped interposing part in the horizontal direction than a virtual vertical plane that contacts an end part of the lower wall portion.

### Claim 4 (depends on 1)

The vehicle seat according to claim 1, wherein
the fold-back part is formed as a continuous body without a hole.

### Claim 5 (depends on 1)

The vehicle seat according to claim 1, wherein
an edge of the fold-back part contacts the cover member without a gap.

### Claim 6 (depends on 1)

The vehicle seat according to claim 1, wherein
an edge of the fold-back part is fixed to the cover member without a gap.

### Claim 7 (depends on 1)

The vehicle seat according to claim 1, further comprising:
a load transmission member that is fixed to the cover member at a position away from the intermediate member in a vehicle fore-and-aft direction and transmits a collision load from a side of a vehicle to the seat frame.

### Claim 8 (depends on 7)

The vehicle seat according to claim 7, wherein
the intermediate member is formed integrally with the load transmission member.
