Telescopically adjustable stay bar, e.g. for seat device, has outer and inner tubes and a clamping ring to be pushed onto the inner tube

摘要

A clamping ring (6) pushes onto an inner tube (2) and has a conical ring section directed towards the open end of an outer tube (3). The clamping ring also engages in a seat's surface designed to correspond with the ring section as a first clamping zone (18) on the outer tube. A union nut (4) holds the clamping ring and connects to the outer tube.
