Known gas-spring dampers have a tendency to leak around the piston (2), which is detrimental to the damping behaviour. Technical measures that compensate said leakage are complex and expensive from a technical production point of view. The invention therefore proposes the reduction of the pivoting movements of the piston axis in relation to the cylinder axis by providing a second pivot joint (10) between the vehicle bodywork (11) and the pivot joint (17) on the pinion (12) and by interconnecting the two pivot joints (10, 17) by means of a connecting element. In addition, the roll bellows (4) are equipped with variable contact surfaces (X', X''), which are pressure-responsive and ensure a stable balance of forces acting on the piston (2) in each position of travel.
