Abstract

A vehicle seat includes: a seatback frame of a resin-formed seatback, including a plate-shaped back face panel portion; a headrest; a seatback pad; a lattice-shaped spring member formed from wire arranged in a lattice shape, attached to the seatback frame at a front side of the back face panel portion, and that resiliently supports the seatback pad from a rear side, with a space formed between the back face panel portion and the lattice-shaped spring member; and a load transmission section provided at one of the lattice-shaped spring member or the back face panel portion and disposed inside the space so as to project out toward the side of the other one of the lattice-shaped spring member or the back face panel portion, such that a gap is formed between the load transmission section and the other one of the lattice-shaped spring member or the back face panel portion.

First claim

What is claimed is:

1. A vehicle seat comprising:
a seatback frame that configures a frame of a resin-formed seatback, and that comprises a plate-shaped back face panel portion disposed at a back face of the seatback;
a headrest that is provided at an upper end of the seatback;
a seatback pad that is provided at a front side of the seatback frame;
a lattice-shaped spring member that is formed from wire arranged in a lattice shape, that is attached to the seatback frame at a seat front side of the back face panel portion, and that is configured to resiliently support the seatback pad from a seat rear side, with a space formed between the back face panel portion and the lattice-shaped spring member; and
a load transmission section that includes a first face and a second face being opposite to the first face, the load transmission section being disposed inside the space such that the first face is attached to one of the lattice-shaped spring member or the back face panel portion and the second face projects out toward the other one of the lattice-shaped spring member or the back face panel portion such that a gap is formed between the load transmission section and the other one of the lattice-shaped spring member or the back face panel portion, and such that the second face does not contact any other member in a normal operation.

2. The vehicle seat of claim 1 , wherein the load transmission section is a shock absorbing member that is attached to the one of the lattice-shaped spring member or the back face panel portion, and that absorbs impact by undergoing deformation.

3. The vehicle seat of claim 1 , wherein the load transmission section comprises a wire engagement portion that engages with the wire configuring the lattice-shaped spring member, and the load transmission section is attached to the lattice-shaped spring member.
