A seat hinge assembly for a vehicle seat having a single position memory feature that permits the seatback to be returned and latched in a predetermined "design" position after having been folded into a memory actuating position. The seat hinge assembly includes a lower hinge member adapted to be secured to the seat bottom, and upper hinge member adapted to be fixed to the seat back, a latching mechanism operable in the latch mode for securing the upper hinge member in a fixed position relative to the lower hinge member and an unlatched mode for releasing the upper hinge member for movement relative to the lower hinge member, and a memory mechanism operable in a non-actuated mode and an actuated mode. The upper hinge member is coupled to the lower hinge member for pivotal movement relative thereto between a forward dumped position and a fully reclined position. In its non-actuated mode, the memory mechanism permits independent actuation of the latching mechanism while in its actuated mode the memory mechanism maintains the latching mechanism in its unlatched mode. The memory mechanism includes a blocker coupled to the lower hinge member for movement between a blocking position and a retracted position, an actuator coupled to move with the upper hinge member and operatively engage the blocker to move the blocker into the blocking position when the upper hinge member is moved into a memory actuating position forward of the adjustment range and to move the blocker into the retracted position upon movement of the upper hinge member from the memory actuating position to a predetermined design position.
