초록 ▼

The invention relates to an apparatus for the level adjustment and/or arching adjustment of a flexibly resilient support element (4) for the lordosic vertebrae of a sitting person, and which is fitted in the frame (1) of a back rest of a seat, each apparatus comprising a gear mechanism (12) including a worm (14), a worm gear (15), a pinion (16) and a tooth element as well as a drive means. According to the invention the gear mechanism is directly connected to the drive means in such a manner that the rigid drive shaft (13) thereof carries the worm (14) engaging into the worm gear (15), the pinion (16) being fixed axially in the worm gear (15) in tooth engagement with a gear wheel (17) in a plane parallel to the worm gear (15). The gear wheel (17) being associated with at least one reel (21) to which the one end of the sheathed cable (23) of a Bowden cable assembly (24) is fixed and onto which it can be wound, the gear wheel (17) comprising at least one projection, which coacts with stop surfaces inside the casing (11) of the gear mechanism (12) to limit in a defined manner the movement of the gear wheel (17). Preferably the drive means is an electric motor.
