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.
