Abstract
A spring system has a first pulling part with a first fastening element connected by a tension spring to a second pulling part with a second fastening element. The pulling parts are moveable relative to one another so as to increase or relieve stressing on the tension spring. A damping device damps the movement of the pulling parts in relation to one another. A cylinder is fastened on the first pulling part and a piston 3 is axially displacesably arranged therein, subdividing the interior of the cylinder into a first cylinder chamber and a second cylinder chamber. A piston rod connected to the piston is arranged on the second pulling part. The interior of the cylinder is connected to the surroundings via one or more restrictor openings.
