Abstract

A vehicle seat includes a side frame of a seat cushion having a side frame opposing portion extending in a front-rear direction of the seat cushion, and a bracket member disposed below the side frame having a bracket opposing portion extending in the front-rear direction and opposing the side frame opposing portion. The side frame opposing portion and the bracket opposing portion are provided such that the side frame opposing portion and the bracket opposing portion come in contact with each other in a state in which the seat cushion sinks rearward and downward when a load acted on the vehicle seat from behind is transmitted to the seat cushion from the seat back via a connection part. An arrangement interval between the bracket opposing portion and the side frame opposing portion is smaller in a front side than in a rear side in the front-rear direction.

First claim

What is claimed is:

1. A vehicle seat comprising:
a seat back;
a seat cushion having a side frame;
a connection part connecting the seat back and the seat cushion; and
a bracket member on a floor side of the vehicle seat that is disposed below the side frame, wherein
the side frame has a side frame opposing portion extending in a front-rear direction of the seat cushion,
the bracket member has a bracket opposing portion extending in the front-rear direction and opposing the side frame opposing portion, which extends along the bracket member in the front-rear direction,
the side frame opposing portion and the bracket opposing portion are provided such that the side frame opposing portion and the bracket opposing portion gradually come into contact with each other from a front side of the vehicle seat toward a rear side of the vehicle seat in the front-rear direction in a state in which the seat cushion sinks rearward and downward when a load acted on the vehicle seat from behind is transmitted to the seat cushion from the seat back via the connection part, and
an arrangement interval between the bracket opposing portion and the side frame opposing portion is smaller in a front side than in a rear side in the front-rear direction of the seat cushion.

2. The vehicle seat according to claim 1 , wherein
a cross-sectional shape of the bracket member in a left-right direction of the seat cushion is varied in the front-rear direction such that the arrangement interval between the bracket opposing portion and the side frame opposing portion is smaller in the front side than in the rear side.

3. The vehicle seat according to claim 1 , wherein
the bracket member is a seat belt anchor bracket.

4. The vehicle seat according to claim 3 , wherein
the seat belt anchor bracket is mounted to an upper rail of a seat slide rail mechanism.

5. The vehicle seat according to claim 1 , wherein
the side frame opposing portion is a lower end portion of the side frame, and
the bracket opposing portion is a side surface portion of the bracket member.

6. The vehicle seat according to claim 5 , wherein
the side surface portion is inclined upward relative to a bottom surface of the bracket member on the floor side of the vehicle seat, and
a width of the side surface portion in a left-right direction of the seat cushion is reduced such that an upper end of the side surface portion approaches the bottom surface of the bracket member as it extends from a front end to a rear end of the side surface portion in the front-rear direction.

7. The vehicle seat according to claim 1 , wherein
the arrangement interval between the bracket opposing portion and the side frame opposing portion is gradually smaller toward a front side than toward a rear side in the front-rear direction of the seat cushion.

8. The vehicle seat according to claim 1 , wherein
the bracket opposing portion is a side surface portion of the bracket member, and
the side surface portion is located at a position higher than a position of a bottom surface of the bracket member fixed to a seat slide rail mechanism.
