Abstract

A bumper arrangement which includes a support having an impact body or piece that is directly or indirectly arranged at a shock absorber mounting for a bumper of a motor vehicle. The impact piece is embedded or surrounded by an elastic bearing pad, with the bearing pad being surrounded by a housing connected with the bumper of the motor vehicle. The housing includes an opening for enabling a passage of a portion of the shock absorber mounting so as to permit a relative movement between the shock absorber and the housing. The impact body or piece includes areas of contact that are disposed opposite each other with one of the areas of contact facing the bumper and the other area of contact facing the shock absorber mounting. The areas of contact are fashioned so as to be convex or bowed outwardly. The bearing pad has a predetermined minimum thickness in an area adjacent to the housing of the top and bottom sides as well as the front and back sides of the impact piece which enables the bumper to only carry out rotating movements about a vertical axis of the motor vehicle.
