ABSTRACT:
A recliner adjuster for adjusting an inclination of a seat back with respect to a seat cushion includes a guide bracket to be secured to one of the seat cushion and the seat back, an internal gear to be secured to the other of the seat cushion and the seat back, a cam rotatably mounted between the guide bracket and the internal gear, a pair of lock gears interposed between the guide bracket and the internal gear so as to be radially slidable in association with rotation of the cam, and a pair of auxiliary lock gears interposed between the guide bracket and the internal gear so as to be radially slidable in association with the pair of lock gears. The rotation of the cam causes the pair of lock gears to radially slide between respective engaging positions, at which engaging teeth thereof are held in engagement with internal teeth of the internal gear, and respective engagement released positions at which the engagement of the engaging teeth of the pair of lock gears with the internal teeth of the internal gear is released. A radial sliding movement of the pair of lock gears between the engaging positions and the engagement released positions causes the pair of auxiliary lock gears to radially slide between respective engaging positions, at which the engaging teeth thereof are held in engagement with the internal teeth of the internal gear, and respective engagement released positions at which the engagement of the engaging teeth of the pair of auxiliary lock gears with the internal teeth of the internal gear is released.
