A lumbar support for use in seats, and particularly vehicle seats, including a band of flexible material (5) such as an elastomeric polymer having mounting means (8) at each of two ends whereby the band is attached to the frame of the seat back rest. At least one of the mounting means (8) includes a dynamic part which is movable relative to another static part so as to thereby vary the effective length of the band (5). Drive mechanism (9) which controls movement of the dynamic part is connected to the dynamic part through a flexible drive connection (10) such as a bowden cable. In one arrangement, the band and the drive mechanism form part of a sub-assembly which is releasably attached to the back rest frame so as to permit convenient exchange of one sub-assembly for another. <IMAGE> |
