Abstract

A variable lumbar support has a support assembly mountable on a seat frame, a pressure element engaged with the support assembly to move in relation to it in a first direction and a second direction. The directions are substantially parallel and opposite and usually vertical. A first traction element engaged with the support assembly and the pressure element moves the pressure element in the first direction and a second traction element engaged with the support assembly and with the pressure element moves the pressure element in the second direction. At least one actuator engaged with the traction elements causes the movement.
