POWERED ACTUATOR FOR LUMBAR UNIT

摘要

A powered lumbar support device (22) includes a resilient panel (44) having a first flange (46) and a second flange (48). The panel is biased in a forward direction for providing an arch in a seat back. A lumbar frame (40) extends downwardly from a support element (34) for slideably supporting the resilient panel. An extending member is affixed t the first flange and projects upwardly from the control module (24), 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.
