Abstract:
1. A vehicle seat comprising: a pair of side frames configuring a portion of a seatback frame serving as framework for a seatback; a deformation origin portion provided to a first side frame which is one of the pair of side frames and acting as an origin when the first side frame deforms due to a collision force imparted to the seatback frame during a rear-on collision; and a deformation suppression unit provided to the first side frame provided with the deformation origin portion, permitting deformation of the first side frame originating at the deformation origin portion and suppressing deformation of the first side frame by a reference amount or greater by the deformation suppression unit making contact with a contacted member provided to the seatback frame when the deformation amount of the first side frame has reached the reference amount, wherein: the deformation suppression unit is coupled to the first side frame so as to be capable of turning, and comprises an engaging portion engaged with the first side frame and a contact portion configured so as to be capable of contacting the contacted member; and the deformation suppression unit turns and the contact portion contacts the contacted member due to the engaging portion moving to follow deformation of the first side frame.
