ABSTRACT:
A powered lumbar support mechanism includes a lumbar plate having a power mechanism having connecting links connected to opposite ends of the plate. One of the connecting links is longitudinally movable to change the convexity of the outer surface of the plate to adjust the lumbar support. The power mechanism includes a housing which retains a threaded rod threaded into a worm gear mechanism held within the housing. The housing also retains a motor having a worm which drives the threaded worm gear. The housing can also incorporate a second threaded rod, threaded to a second threaded worm gear also fixed within the housing such that the end of the second threaded rod is connected to a seat support so as to allow for the adjustability of the vertical position of the lumbar mechanism.
