Claim:
1. A braking device for braking a movement of a first vehicle part and a second vehicle part with respect to each other, the braking device comprising: a housing having an inner bore; a piston having a shaft extending in the inner bore along a longitudinal axis and being mounted on the housing such that the shaft is displaceable along the longitudinal axis with respect to the housing along a displacement path; a brake arranged within the inner bore of the housing and configured to provide a friction force for braking a displacement movement of the piston and the housing with respect to each other at least within a portion of the displacement path; a tensioning device configured to act radially with respect to the longitudinal axis onto the brake to provide a radial tensioning force; wherein the brake is in frictional contact with the housing or the piston or a component connected to the housing or the piston at least within said portion of the displacement path; and wherein the tensioning device comprises a wrap spring circumferentially extending about the longitudinal axis for acting radially onto the brake.
