Abstract: An adjustable lumbar support assembly for a seat has a curved lumbar support member that is made from a plastic material and an adjustment mechanism operatively connected to the curved lumbar support member for adjusting between various degrees of curvature. The curved lumbar support member may include a plurality of reinforcing ribs that allow a greater degree of curvature adjacent one end of the element than the degree of curvature adjacent the other end of the element. The reinforcing ribs allow for varying degrees of curvature because the cross section of the ribs varies. Further, the reinforcing ribs are integral with the curved lumbar support member. The adjustable lumbar assembly could also include at least one resilient metal strap connected to the curved lumbar support member that allows a greater degree of curvature adjacent one end of the curved lumbar support member than the degree of curvature adjacent the other end of the element.

Abstract: The invention relates to an apparatus for adjusting the arching of a resiliently flexible support element for supporting the pelvic and/or lumbar vertebrae in a back rest of a seat including an arching means. According to the invention, a flexible support element is suspended in a seat by multiple guide rods, and a Bowden cable is connected to the support element in such a manner as to arch the support element when traction is applied thereto. A restoring spring draws the support element from its arched position. An intermediate spring is used in combination with the Bowden cable such that the support element resiliently yields to major pressure. Another spring provides compensating forces to counteract the arching adjustment, thereby substantially reducing the force to be exerted in order to adjust the degree of arching.
