Abstract

A powered lumbar support device includes a panel having a first end and a second end. The panel is biased in a forward direction for providing an arch in a seat back. A lumbar frame extends downwardly from a support element for slideably supoprting the panel. A first cable is affixed to one of the ends of the panel and to an arching rack of a first gear box. Linear movement of the arching rack transfers motion to one of the ends to change the distance between the ends by moving the first cable. The powered lumbar support device includes a second gear box having a moving rack and a moving pinion for vertically shifting the lumbar support device. The second gear box may also be used to actuate additional support features, such as a bolster.
