Abstract: A reclining vehicle seat hinge assembly includes a first housing, a second housing having a plurality of teeth, a primary cam member having primary and secondary camming surfaces, a primary spring, and a secondary cam having at least one spring arm and a plurality of windows, with each window having at least one camming edge. Each of a pair of primary pawls is configured to be driven into an engaged position by a primary camming surface of the primary cam and a camming edge, and into a disengaged position by a camming edge of the secondary cam. Each of a pair of secondary pawls is configured to be driven into an engaged position by a secondary camming surface of the primary cam and into a disengaged position by a camming edge of the secondary cam.

Abstract: A recliner mechanism includes a base housing adapted to be held to a seat cushion frame and a sector housing adapted to be held to a seat back frame. The sector housing is rotatable about a pivot axis and has a plurality of teeth. A locking pawl has a plurality of teeth engageable with the teeth of the sector housing. The locking pawl is movable between a locking position with the locking pawl teeth engaging the sector teeth to prevent rotation of the sector housing and a releasing position with the locking pawl teeth disengaged from the sector teeth to permit rotation of the sector housing. A cam is rotatable about the pivot axis and is rotatably connected to the locking pawl about an eccentric axis to move the locking pawl between the locking position and the releasing position in response to rotation of the cam about the pivot axis.

Abstract: A reclining vehicle seat hinge assembly includes a first housing, a second housing having a plurality of teeth, a primary cam member having a pair of primary camming surfaces, and a secondary cam having a plurality of camming surfaces and driveable by the primary cam. Each of a pair of primary pawls is configured to be driven into an engaged position by a primary camming surface of the primary cam and into a disengaged position by a corresponding camming surface of the secondary cam. Each of a pair of secondary pawls has the same construction as the primary pawls and is configured to be driven into engaged and disengaged positions by corresponding camming surfaces of the secondary cam.
