ABSTRACT:
An activating device for the release tappet of a longitudinally adjustable gas spring. The device is shiftable parallel to the longitudinal axis of the gas spring between a fixed and a release position, and comprises an activating lever fixable in two end pistons. A device connecting the piston of the gas spring with a first housing part of the activating contrivance is effected so that a release tappet projects into a first housing part by means of a ball beneath the release tappet. A second housing part is located beneath the first housing part and the ball in contact therewith. A pivotably stored activating lever section is provided with angularly transposed, coordinated recesses of different depths.
