<p>The present invention relates to a height adjustable spine support as it is in particular used in car seats. The spine support according to the invention comprises at least one bending element (20, 20') a plurality of supporting elements (30) essentially orthogonal arranged to the at least one bending element (20) and connected with it; and a first operating element (40, 40') arranged such that its operation leads to a bending of the at least one bending element (20). According to a preferred embodiment, two pairs of bowden cables (40, 60) for adjusting the spine support are operated by a control unit (90) comprising two coaxially arranged axles (91, 92). Preferably on at least one of the axles (91, 92) a receiver (96) for the inner steel cables of one of the two pairs of bowden cables and a receptacle (97) for the corresponding covers of the bowden cables are provided. In the preferred embodiment the receiver (96) and the receptacle (97) approach each other or move away from each other under a rotation of the axle, depending on the direction of the rotation. The relative movement of the receiver (96) and the receptacle (97) is preferably achieved by the use of left-handed and right- handed threads on the axle.</p> |
