LORDOSENSTÜTZVORRICHTUNG

In an adjustable lumbar support device, a wire framework essentially consisting of two lateral side wires (4) and a plurality of transverse wires (8) is connected to a seat frame via a pair of support means (5), each preferably formed of a wire. A first connecting portion (5a) of the support means (5) is pivotably connected to a respective longitudinal side of the seat frame. A second connecting portion (5b) is connected to one of the lateral side wires (4). A third connecting portion (5c) is coupled to the third connecting portion (5c) of the support means (5) located on the opposite longitudinal side of the seat frame by means of an actuating means (10), preferably formed by a Bowden cable. In response to the action of the actuating means (10), the third connecting portions are pulled toward each other, thereby pivoting the support means (5) and moving the wire framework in a direction perpendicular to its plane.
