Abstract: A recliner mechanism including an anti-back drive device for releasably securing a seat back with respect to a seat cushion is provided. The mechanism may include an upper gear plate affixed to the seat back and a lower gear plate secured to a seat bottom. Wedges may be mounted in relation to the upper gear plate. A clutch spring may be located within the lower gear plate and a split bushing may be disposed between the clutch spring and the lower gear plate. A split leaf bushing may be disposed between the wedges and the clutch spring. A wedge spring may engage the wedges biasing them against the split leaf bushing. Upon rotation of a driver, the clutch spring and the one or more wedges are arcuately displaced and lock the seat back in position.

Abstract: A continuous manual seat recliner mechanism with an integrated lock includes an upper gear plate and lower gear plate in geared connection with the upper gear plate. The upper gear plate is able to rotate eccentrically in relation to the lower gear plate. A coiled locking spring is located within a central bore of a lock cylinder which is fixed to the lower gear plate so that an outside surface of the locking spring may frictionally engage the lock cylinder to prevent the lock cylinder and, thereby, the lower gear, from rotating. The ends of the lock spring engage with a knob hub and a driver hub such that rotation of the knob hub unlocks the recliner to allow adjustment by the operator, while rotation of the driver hub locks the recliner mechanism.
