Abstract

A spine support 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). 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. 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.
