摘要

The drive has outer and inner tube elements (54, 63) displaceable into each other and connected with a seat portion such that the seat portion is upwardly and downwardly movable by movement of the tube elements relative to each other. A generator-powered brake stops the drive during power failure. The brake is arranged within a drive unit (57). The outer tube element has a sealing comprising a plastic ring supporting a sealing ring against an inner section and a fixing clip. The tube element has a mushroom-shaped counterpart (64) cooperated with a profile.
