A seatback latch mechanism is provided having a quadrant that is adapted to be secured to support structure associated with a seat assembly or a motor vehicle. The quadrant includes a cam segment defining a dwell surface which extends between first and second locking surfaces. The seatback latch mechanism further includes a seatback support member supported for pivotal movement relative to the quadrant between an "upright" position and a "folded" position. The support member is adapted to support the seatback of a seat assembly for pivotal movement relative to the seat bottom. A locking pin is mounted to the seatback support member for selectively engaging one of the first or second locking surfaces, thereby defining the upright position and the folded position, respectively. The seatback latch mechanism further includes a release actuator for disengaging the locking pin from the first and second locking surfaces, whereby the locking pin engages the dwell surface to permit the seatback to be moved to the other of the upright and folded positions.
