Vehicle seat

摘要

A vehicle seat capable, with a simple, lightweight structure, of improving a whiplash moderation effect from a head rest. In the vehicle seat (10), when there is an impact at a rear face of the vehicle, a support frame (50) that is fixed to a reclining rod (46) separately from a seatback frame (32) supports the waist area of a seat occupant from the vehicle rearward side. Thus, a load from the seat occupant that is inputted to the seatback frame (32) is reduced. Therefore, a displacement amount (deformation amount) of the seatback frame (32) to the vehicle rearward side may be suppressed. Thus, a duration until the head area of the seat occupant abuts against a headrest (16) may be shortened. Moreover, the support frame (32) that only supports the waist area of the seat occupant need only be fixed to the reclining rod (46). Therefore, a simple, lightweight structure may be formed.
