ABSTRACT:
A seat recliner for interconnecting a seatback for pivotal movement relative to a seat bottom is provided. The seat recliner includes a housing and a recliner rod having one end supported for movement relative to the housing, a lock pawl retained in a predefined memory position relative to the housing for movement between a locked position and a released position, and a recline actuator assembly which can be selectively actuated for moving the lock pawl from its locked position to its released position to adjust the use position of the seatback. The seat recliner further includes a lock pin supported from the housing for movement between a first position and a second position, and a dump actuator assembly for selectively moving the lock pin from its first position to its second position. In its first position, the lock pin retains the lock pawl in the memory position. However, with the lock pin in its second position, the lock pawl is released for movement with the recliner rod to permit the seatback to be folded to its forward dumped position. The seat recliner is operable to retain the lock pin in its second position when the lock pawl is moved out of the memory position. When the seatback is returned to its previous use position, the resulting movement of the recliner rod causes the lock pawl to return to the memory position and the lock pin to return to its first position for relatching the seatback in its previous use position.
