Abstract: A damper has a cylinder and a piston, the piston having two or more parts. A first piston part consists of a rubber-elastic material forced against the cylinder wall during a damping stroke. A second piston part consists of a material that is stiffer in comparison to the rubber-elastic material. The second piston part as seen in the radial direction lies between an area of the first piston part and the cylinder wall. The first piston part may have at least two sections of different hardnesses over its lengths. The piston could also include a piston part that is radially forced outwards to rub against the cylinder wall during damping, the piston part being made as a solid body of a material with rubber-elastic properties which becomes flattened under pressure, deforming in such a way that a friction seal is created between the piston part and the cylinder wall.

Abstract: A damper has at least two damping components which are mounted such that they can move relative to each other during a damping stroke. A damping medium acts between the damping components, and at least one actuating element is operatively connected to the first damping component at least during the damping stroke of the damper. A locking device is arranged between the second damping component and a retaining part. The locking device couples the second damping component fixedly to the retaining part during the damping stroke of the damper. During the return stroke of the damper, the locking device decouples the second damping component from the retaining part so as to realize a freewheeling motion such that, during the return stroke of the damper, the second damping component moves together with the first damping component.
