Longitudinally adjustable gas spring with a longitudinally adjustable column

摘要

A longitudinally adjustable gas spring has a housing of which the edge on the side where the piston rod exits, projects freely. With the housing being moved as far as possible into an upright tube of a longitudinally adjustable column, the edge can at least in part overlap a damping member located on the piston rod, and with the housing being extracted as far as possible from the upright tube, it can serve additionally as a guidance in a guide bush of the upright tube.
