Abstract
A vibration damper for vehicles comprises a work cylinder in which a piston is guided axially by a piston rod. The piston divides the work cylinder into two work spaces filled with damping fluid. A tension stop is provided between the piston and a piston rod guide, wherein a tension stop element including a flexible part and a reinforcing ring is arranged between a support fastened to the piston rod and the piston rod guide. The reinforcing ring limits the deformation of the flexible part of tension stop when subjected to force during operation so that permissible shearing stresses of the flexible part are not exceeded.
