Abstract

The lumbar support in the seat backs of especially motor vehicle seats has a support plate (9) which is adjustable in its curvature and/or height and which consists of longitudinal members (1,2,7,8) formed as wires and cross members (3-6) at right angles to them and rigidly interconnected to them at the crossover points. The cross members are constructed as injected plastic parts which fit round the extrusion coated longitudinal members at the crossover points. The cross members are formed as rails and may be profiled.
