Abstract
A stop damper including a damper member with a cylinder. A piston is moveably guided inside a receiving space of the cylinder. The cylinder has a sliding surface against which the piston rests with a sealing element. A braking force that acts upon the piston can be applied using the air pressure generated in the receiving space because the piston is displaced, the receiving space being connected to the environment via an air-conducting connection to reduce the air pressure. In order to improve the braking effect of the sliding element, the sealing element of the piston and the sliding surface of the cylinder can contact each other in at least some areas via a defined rubbing surface geometry, the peak-to-valley height of the sliding surface being <1 μm and the peak-to-valley height of the facing surface of the sealing element being =4.5 μm in at least some areas.
