Abstract:
PCT No. PCT/AU95/00123 Sec. 371 Date Sep. 9, 1996 Sec. 102(e) Date Sep. 9, 1996 PCT Filed Mar. 10, 1995 PCT Pub. No. WO95/24144 PCT Pub. Date Sep. 14, 1995An adjustable lumbar support for use in the backrest of a seat, the lumbar support having an elongate flexible band which extends longitudinally between the sides of the seat backrest and which has an effective length capable of variation so as to thereby vary the rearward curvature of the band when the lumbar support is in use. The band includes two parts which overlap in a region intermediate the length of the band and which are interconnected through a drive device including a rotatable cam. The cam interacts with the band parts in such a way that rotation of the cam causes a change in the degree of overlap between those parts and thereby changes the effective length of the band. The cam is contained in a housing and an actuator such as an electric motor can be mounted on that housing to form an integral part of the lumbar support assembly.
