ABSTRACT:
Impact-absorbing bumper mount with two telescoping tubes, in particular for motor vehicles, to decelerate a vehicle via damping forces when the vehicle strikes an obstacle, whereby a work piston is guided in a sealed manner in one of the tubes, and with which, in addition to a weight reduction, it is also possible to simplify the fabrication process, reduce costs and achieve sufficient corrosion protection. The invention teaches that this problem can be solved by tubes which have recesses on their inside and outside, and which are coated with a polymeric material.
