ABSTRACT:
Presentation of an improved adjustable lumbar support mechanism with a remote control push-button and cable (10) for use in a seat backrest. The cable is routed to a hydraulic (or pneumatic) positioning cylinder (12) which has a locking capability and integral spring-load force to permanently preload a lumbar support panel (20) in a direction opposing the pressure from the seat occupant's back. A new principle of operation of the "manual" lumbar support is utilized, in which the force from a human's back is used to conveniently readjust the lumbar position (counterbalancing the spring), not the force in the operator's hand. The new lumbar system is a fast-acting device compared to traditional knob-driven units and permits frequent, quick, and easy readjustment of lumbar position whenever the push-button is depressed.
