Abstract

A seat recliner of the disclosure includes an adjustment mechanism that adjustably controls the angular orientation of a seat back relative to an associated seat cushion and also includes a latch that releases the seat back for forward tilting movement to an easy-enter position. Seat back and cushion arms are pivotally interconnected along the tilting axis about which the seat back moves and are positioned relative to each other thereabout by the cooperable action of the adjustment mechanism and the latch. A positioning member of the adjustment mechanism is pivotally located relative to the seat cushion arm about the axis by a locking dog that is moved between locking and nonlocking positions by the cooperable action of a cam and a cam actuator. Dog movement to a nonlocking position releases the positioning member to permit adjustment thereof and a consequent change in the angular orientation of the seat back. The latch is mounted on the seat back arm and engages the positioning member in a latching position to prevent forward tilting seat back movement. In a nonlatching position, the latch disengages the positioning member to permit the seat back to pivot forwardly independently o…
