Abstract: A multifunction seat control system includes a pulley mechanism in an enclosure, an actuation shaft to attach an external handle, and multiple latch actuation cables. The pulley mechanism includes multiple circumferential slots in which the cables ride, and cable-end entryways through which associated cables ends can be inserted. A lockout device detects a seat-back position to selectively limit the rotational travel of the pulley mechanism. The pulley mechanism is rotationally actuated to a predetermined angle to release a seat-back latch so the seat back can recline or fold forward, and beyond the predetermined angle to release seat-bottom latches so the seat can tumble into a stowage configuration. The control system optionally includes a headrest cable to release a headrest as the seat back is folded forward, and a release strap to actuate the pulley mechanism from behind the seat.

Abstract: In the field of vehicle seats there is a need for an improved vehicle seat back tilt adjustment assembly that allows a user selectively to make small or large adjustments to the inclination of a vehicle seat back. A vehicle seat back tilt adjustment assembly comprises a guide member securable to a vehicle body; and an intermediate mechanism moveably coupled to the guide member. The intermediate mechanism includes first and second locking elements. The first locking element is moveable between a first configuration in which it is engagable with a vehicle seat back to secure the seat back to the intermediate mechanism and a second configuration in which the seat back is disengagable therefrom to allow the seat back to move independently of the intermediate mechanism. The second locking element selectively engages the guide member to secure the position of the intermediate mechanism relative to the guide member.
