Automobile seat

Abstract

An automobile seat includes a seat cushion having a seat cushion frame, a seat back tiltably mounted on the seat cushion, and a headrest mounted on an upper portion of the seat back. The automobile seat also includes a pair of side frames mounted on the seat cushion frame, a seat back frame mounted on the pair of side frames so as to be swingable within a limited range of angle, and a recognition mechanism mounted on the seat back frame. In a normal sitting condition, the seat back frame is held on the pair of side frames at a first position, while when a load greater than a predetermined value is inputted from behind, the seat back frame swings toward a second position different from the first position to thereby move the headrest forward. The swinging motion of the seat back frame can be recognized by the recognition mechanism.
