ABSTRACT:
In a chair back for e.g. an automobile seat, a support part suspended in a frame has two elongate side elements along the chair back, which are interconnected by means of connecting members and held tensioned by suspending the side elements in the frame. A tensioning device, connected to both ends of each side element, can subject the side elements to such great buckling forces as to make them arch, with the arch center facing forwards. Thereby a lumbar support is formed wherein the tensioning devices can be actuated by an adjusting means for resetting the lumbar support by changing the size of the arch.
