## Abstract

Provided is a vehicle seat having a variable cushion length. The vehicle seat includes: a front panel of metal arranged on a front-end side of a seat cushion to form a frame of the seat cushion; a sliding device allowing a movable portion to be displaceable and including a sliding member of resin displaceable relative to the front panel in seat front-rear directions; and a bracket of metal that is coupled to the front panel in a manner displaceable relative to the front panel in the seat front-rear directions and that is displaced integrally with the sliding member, the bracket transmitting a load acting on the movable portion to the front panel.

## Claims

### Claim 1

A vehicle seat including a movable portion at a front-end side of a seat cushion and having a variable cushion length, the vehicle seat comprising:
a front panel of metal arranged on the front-end side of the seat cushion to form a frame of the seat cushion;
a sliding device allowing the movable portion to be displaceable, the sliding device including a sliding member displaceable relative to the front panel in seat front-rear directions; and
a bracket of metal that is coupled to the front panel in a manner displaceable relative to the front panel in the seat front-rear directions and that is displaced integrally with the sliding member, the bracket transmitting a load acting on the movable portion to the front panel.

### Claim 2 (depends on 1)

The vehicle seat according to claim 1,
wherein a shape of an end of the bracket in the seat front-rear directions is substantially U-shape or substantially L-shape.

### Claim 3 (depends on 2)

The vehicle seat according to claim 2,
wherein the bracket includes a standing portion substantially parallel to a vertical direction, and
wherein a vertical dimension of the standing portion on a front-end side thereof is larger than a vertical dimension of the standing portion on a rear-end side thereof.

### Claim 4 (depends on 2)

The vehicle seat according to claim 2,
wherein a portion of the bracket facing the front panel contains a through hole having an ellipse-like shape extending in a displacement direction of the bracket, and a bolt passing through the through hole is fixed to the front panel, and
wherein a burring portion extending toward the front panel is provided at least to a portion parallel to a major axis direction of the through hole in an outer circumference of the through hole.

### Claim 5 (depends on 4)

The vehicle seat according to claim 4,
wherein a spacer of resin is arranged between a head portion of the bolt and the bracket.

### Claim 6 (depends on 1)

The vehicle seat according to claim 1,
wherein a support portion of resin fixed to the front panel is arranged between the bracket and the front panel, the support portion being slidably contactable with the bracket, and
wherein a portion of the support portion directly facing the bracket includes a groove extending in the displacement direction of the bracket.
