Abstract
A powered lumbar support device includes a resilient panel having a first flange and a second flange. 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 supporting the resilient panel. An extending member is affixed to the first flange and projects upwardly from the control module, which is retained in position by a compliant spring. The control module includes a drive mechanism for changing the arch in the basket by changing the distance between the first flange and the second flange by extending and retracting the extending member.
