Abstract
A lordosis-support backrest for an automotive vehicle has a pressure element mounted upon vertical wires affixed to the frame of the backrest and guided along these wires. A transmission on the wires driving a rack on the pressure element displaces the pressure element along the wires while a similar transmission affixed to the pressure element at an upper portion thereof has its rack connected by a rocker lever and links to upper and lower portion of the pressure element to control the degree of bulging of the pressure element. The transmissions are driven by flexible shafts connected to respective motors mounted at spaced locations on the frame.
