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.

Seat back for vehicle and seat for vehicle including the same

A vehicle seatback including a seatback frame provided with a pair of seatback side frame portions and a seatback upper frame portion that connects together upper end portions of the pair of seatback upper frame portions along the seat width direction, and a support member attached to the seatback frame. The support member is provided with a lower neck bearing portion covering the seatback upper frame portion, and a shoulder bearing portion disposed further towards the front than the seatback upper frame portion in the seat front-rear direction. When a load of a specific value or greater acts on the occupant towards the rear in the seat front-rear direction, the shoulder regions of the occupant are pressed against the shoulder bearing portion, suppressing movement of the occupant towards the rear in the seat front-rear direction.
