An adjustable lumbar support, especially for use in a car seat has : (a) at least one bending element (20); (b) a number of support elements (30) which are located vertically to the bending element(s) and are connected to this/these; and (c) an operating element (40) which is located so that its operation leads to a bending of the bending element(s). There are two parallel vertically running bending elements. The number of support elements (30) consist of lattice-like elements which together with the two bending elements are connected to a flexible frame. The two bending elements are formed out of two spiral springs and out of linked bars. The operating element consists of a push-pull cable which can also transmit thrust forces. |
