This invention is a lumbar support device consisting of a flexmat and a supporting mechanism. The invention is capable of providing an infinite number of vertical adjustment points. The supporting mechanism is connected to the flexmat via slide elements and may travel up and down the side rails of the flexmat assuring infinite adjustment positions for the lumbar support. The movement of the supporting mechanism both vertically along the flexmat and horizontally relative to the seat back is accomplished through the use of wire cables, tractions cables, and a series of pulleys. Use of the pulley system reduces the load of the actuators needed in this device and helps avoid any interference that may occur with other seat components including foam.
