A recliner clutch mechanism for use with a vehicle seat having a seat bottom and an upwardly extending and pivotally movable seat back. A lock plate having first and second faces is secured in translating fashion between the seat bottom and seat back. A first actuating plate is located in proximity to the first face of the lock plate and urges the lock plate to engage against the seat back in a first position. A second actuating plate is located in proximity to the second face of the lock plate and causing the lock plate to disengage from the seat back in a second release position. A spring engages the seat back in a forward rotating direction. A release handle and lever assembly is in operative communication with a secondary spring and, upon actuation, releases the engaging force exerted by the first plate, concurrent with influencing the second actuating plate against the lock plate in the second release position.
