Abstract: Impact damper for motor vehicles, the impact damper having two tubes which can be pushed one inside the other, the inner tube consisting of a first and second fluid chamber and a gas chamber separated from the first fluid chamber by a separating piston. A third fluid chamber, separated from the second fluid chamber by a work piston can extend the tubes relative to one another by changing the pressure within the fluid chambers.

Abstract: Impact damper for motor vehicles, the impact damper having two tubes which can be pushed one inside the other, the inner tube having a first and second fluid chamber and a gas chamber separated from the fluid chamber by a separating piston. A third fluid chamber is located behind a work piston and the tubes can be retracted or extended by changing the pressure within the fluid chambers of the impact damper.

Abstract: A yielding arrangement of a bumper at the body of a motor vehicle in which the bumper is connected with a longitudinal bearer by way of impact shock absorbers under interposition of a deformation member. For purposes of obtaining a high energy absorption with a comparatively large deformation displacement, the deformation member is essentially formed by several roll sheet metal members which extend substantially parallel to the impact shock absorber along the inner walls of a housing secured at the longitudinal bearer. The roll members are connected at their ends opposite the bumper with the housing and at their other ends are secured at the impact shock absorber.

Abstract: The lateral end sections of a bumper each carry a sliding member with a U-shaped cross-sectional profile. The two legs of each are surrounded in fork-like fashion by the legs of a retaining member attached to the vehicle body also having a U-shaped cross-sectional profile. The legs of the sliding member each are provided with an intermediate layer of a rubber-elastic material. On the inside of the legs of the retaining member, inclined surfaces are provided which are inclined in mirror-image symmetry to a plane of symmetry of the U-shaped cross-sectional profile of the retaining member and which extend toward the base. These inclined surfaces respectively include a curvature. A second curvature adjoins this first-mentioned curvature.
