摘要： A seat reclining mechanism comprises a plurality of lock gear members. One of the plurality of lock gear members has a protrusion which protrudes toward an internal gear member. The internal gear member has a first free-zone arc portion formed along a circle having a center on a rotation axis and adapted to allow the protrusion to be in contact therewith when the lock gear members are located at a position where external teeth of each of lock gear members are not in meshing engagement with internal teeth of the internal gear, and a second free-zone arc portion formed along the circle to have an arc length different from that of the first free-zone arc portion and adapted to allow the protrusion to be in contact therewith when the lock gear members are located at the position.

摘要： A recliner adjuster includes a guide bracket to be fixed to one of a seat cushion and a seat back that can pivot with respect to the seat cushion, an internal gear to be fixed to the other of the seat cushion and the seat back, a cam interposed between the guide bracket and the internal gear, a pair of lock gears radially slidable in association with an operation of the cam, and a mounting ring for assembling the guide bracket and the internal gear together with the cam and the pair of lock gears interposed therebetween. The mounting ring has a flat annular portion and a cylindrical side portion joined to one of the guide bracket and the internal gear. An outer peripheral surface of the other of the guide bracket and the internal gear is held in sliding contact with an inner surface of the cylindrical side portion of the mounting ring to thereby radially position the other of the guide bracket and the internal gear.

摘要： 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.
