ABSTRACT:
An actuator for a lumbar support device possessing a symmetrical housing in that key holes are present on both sides of such housing. The present invention's housing, with key hole slots diametrically opposed on one end, allows the actuator to be installed more easily in any orientation, in either driver or passenger side seats. With the dual key hole housing, the extra time and effort associated with ensuring that the correct side of the housing is being used is eliminated as the dual key holes allow the tension cable wire and tension cable wire end to be inserted into either side of the housing during assembly of the lumbar support system. The elimination of this concern will save valuable time and money in the actuator assembly process.
