ABSTRACT:
A simplified, low-cost actuator used in conjunction with a lumbar support device designed to significantly decrease manufacturing costs and assembly time. The present invention produces similar movement as the more expensive actuators but does so with a considerably smaller number of parts. The actuator consists merely of four pieces—a handle, a spring, a plunger, and a mounting bracket. The symmetry of design of this actuator allows it to be installed more easily in any orientation and on either side of the seat. Furthermore, the actuator may be adapted for use with a tension cable or a drive rod. The simplicity, low-cost, and ease of use associated with this actuator makes it an attractive alternative to other actuators disclosed in the prior art. Finally, this actuator allows adjustable lumbar support to be offered in a cost effective manner in lower tier seating.
