Abstract
An assembly for adjusting a lumbar region of a seat having a back frame. A seat support adapted for suspension in the frame is movable between first and second lumbar positions. An actuator is operatively attached to and concurrently moves with the support, and has a chassis mount and a drive mount selectively movable therewith between first and second positions. A wire extends between longitudinal ends adapted for attachment to the frame. A first guide slidably supported along the wire is coupled to the support and to the chassis mount. A second guide slidably supported along the wire is coupled to the support and to the drive mount. Movement of the drive mount from the first position urges the guides away from each other towards the ends of the wire such that the actuator and the seat support move toward the second lumbar position as a unit.
