ABSTRACT:
A gas spring substantially comprises a cylindrical housing, closed on one end, and a piston rod located concentrically in it and extending in a sealed manner from its other end, the piston rod being provided on its end located in the housing with a piston assembly resting on the inner wall of the housing and being guided in a damped manner. In order to attain a relatively broad hysteresis, which is desirable when the gas spring is used for retaining the upper parts of sun-tanning benches or automobile hatchbacks or the like, the piston assembly has a friction damping liner resting against the inner wall of the housing and made of an expanded plastic, which is open-celled and impregnated with lubricant on its friction face resting on the inner wall.
