Abstract

PROBLEM TO BE SOLVED: To prevent the seated attitude of a seat from being inhibited by receiving a lower arm and an upper arm on the opposite side to the arranged side of a lock device via the contact between a pin and a groove, and regulating the backward warp of a seat back frame. SOLUTION: A pin 15 is extended to the side from an upper arm 6' on the opposite side to the arranged side of a lock device, and a bracket 17 having a groove 16 opened forward to the upper section of the inside face of a lower arm 4' is fixed to a seat cushion frame. When a seat back is set to a seating position, a stopper pin is engaged with a hook member, the pin 15 of the upper arm 6' is brought into contact with the groove 16 of the bracket 17 provided on the lower arm 4'. Even when an excessive load is applied, the backward warp of a seat back frame is regulated, and the twist of the seat back is eliminated, thereby the seated attitude of a seat can be prevented from being inhibited.
