<p>An adjustable lumbar support which includes an elongate flexible band (3) arranged to extend between and be connected to opposite sides (7) of a seat back rest. The connection with the seat back rest at at least one of the band is such that the end of the band is movable in the longitudinal direction of the band relative to the seat back rest so as to vary the degree to which the band curves rearwardly. Control of that movement is effected through a flexible cable (9) connected to the band at one end and connected to an actuator (4) at its opposite end. The cable has a tubular cover (10) and a wire core (11) slidable longitudinally within the cover, and the cable connections are such that the wire core (11) forms a static part of a drive connection between the band and the actuator, and the cable cover forms a dynamic part of that connection. It is preferred that a respective cable is connected to each end of the band, and that each of those cables is connected to a common actuator.</p> |
