Abstract
A waist receiving portion, which is provided at a support member, is curved to form a convex shape toward a front side in a seat front and rear direction in side view. Accordingly, when a waist portion of an occupant is pressed against the waist receiving portion, the change of the shape of lumbar vertebrae is suppressed. For this reason, since it is possible to reduce the difference between a timing when a head portion of the occupant is pressed against a headrest and a timing when a neck portion of the occupant is pressed against a neck receiving portion, it is possible to suppress swing of the head portion of the occupant about the neck portion as a fulcrum in the seat front and rear direction. Therefore, a burden to the neck portion of the occupant is reduced.
