  • Patent number: 6626274
    Abstract: A vibration damper includes a rebound, in particular a rebound spring. The vibration damper includes a piston which is formed on an axially movable piston rod and which separates two working chambers in a cylinder, the working chamber penetrated by the piston rod being closed off with a lid and containing the rebound. An out-stroke of the piston rod relative to the cylinder includes an idle-stroke which starts at a minimum out-stroke and in which the rebound does not counteract the piston rod movement, a working-stroke which ends at a maximum out-stroke and in which the rebound counteracts the piston rod movement, and a point of application at which the idle-stroke ends and the working-stroke begins. The vibration damper further includes an arrangement configured to adjust the point of application.
