VEHICLE SEAT

摘要

A vehicle seat includes: a seat pad; and an air bag placed on a back side of the seat pad and configured to be expandable. The seat pad includes a jump-out portion and an unfolding portion extending. When the air bag jumps out, the unfolding portion is pushed aside while deforming in a bending manner from a part serving as a base point at the time when the unfolding portion is pushed aside by the air bag. The unfolding portion includes a deformable portion that is easy to deform as compared with other parts of the unfolding portion, the deformable portion being placed at the part serving as the base point, and at the time when the air bag jumps out, the deformable portion deforms so as promote the unfolding portion to deform in a bending manner so that the unfolding portion is pushed aside toward the one side.

1. A vehicle seat comprising:
a seat pad forming a seat outer shape and elastically supporting an occupant; and an air bag placed on a back side of the seat pad and configured to be expandable due to inflow of air, wherein: the seat pad has a jump-out portion which is fragile as compared with other parts of the seat pad and from which the air bag jumps out, and an unfolding portion extending from the jump-out portion toward one side of the seat; when the air bag jumps out from the jump-out portion while pushing the unfolding portion aside toward the one side, the unfolding portion is pushed aside while deforming in a bending manner from a part serving as a base point at the time when the unfolding portion is pushed aside by the air bag; the unfolding portion includes a deformable portion that is easy to deform as compared with other parts of the unfolding portion, the deformable portion being placed at the part serving as the base point; and at the time when the air bag jumps out, the deformable portion deforms so as to promote the unfolding portion to deform in a bending manner so that the unfolding portion is pushed aside toward the one side.
