Abstract: A crash box for incorporation between a bumper beam and a side rail of a motor vehicle includes an outer tube which is made of a hardened steel material, and an inner tube which is held in the outer tube in a way that the inner and outer tubes are movable in relation to one another. When shifted by the outer tube, the inner tube deforms to thereby convert impact energy in deformation energy, thereby decreasing electric energy.

Abstract: A motor vehicle includes a compressed-gas tank which is disposed in a wheel well of a spare wheel. The compressed-gas tank has a circular-cylindrical configuration defined by an axis of rotation and includes tie elements in parallel relationship to the axis of rotation.

Abstract: In a method of making a hybrid structure, at least one support body is fixed in a tube component which is then placed in an injection molding tool. An injection-molded part is injection-molded to an outer surface of the tube component in an area of the support body. As a result, the tube component is inwardly deformed, when regions adjacent to the support body are exposed to an injection pressure, and forms indentations for engagement of the injection-molded part.

Abstract: In a method of making a bumper structure of a motor vehicle, a blank of quenched and tempered steel is formed into a U-shaped bumper beam having a middle part and attachment parts which adjoin the middle part on opposite ends and define crash boxes. The middle part of the bumper beam is hardened either during or after the blank is formed into the bumper beam.

Abstract: A crash box for placement between a bumper beam and a side rail of a motor vehicle includes a longitudinal profile made of two U-shaped shells having overlapping ends sized to realize a material doubling for increasing side stiffness and to suit the side stiffness to a load level. A flange plate is provided on a side-rail-proximal end of the longitudinal profile and has an opening for passage of the longitudinal profile. The side-rail-proximal end of the longitudinal profile is configured with a collar which is turned outwards. The collar rests against the flange plate and is joined with the flange plate. In the event of a collision, the longitudinal profile of the crash box is moved into the side rail as the longitudinal profile folds into the side rail starting from the flange plate, while the side-rail-proximal end of the longitudinal profile remains secured to the flange plate.

Abstract: A safety device for a motor vehicle includes a deformation element which is arranged between a bumper beam and a side rail and moves into the side rail in the event of an impact. The deformation element is configured in the form of an evertable tubular member having a side-rail-proximal rear end provided with an abutment ring. Operatively connected to the deformation element is an actuator which is provided to release a displacement of the deformation element into the side rail in a predefined speed range by liberating the abutment ring in relation to the side rail in a release position, and to block the displacement of the deformation element into the side rail, when the speed range is exceeded or a vehicle speed is below the speed range, by locking the abutment ring in relation to the side rail in an engagement position.

Abstract: A bumper for the front or rear section of a motor vehicle includes a cross member having a shell of U shaped cross section so as to define two legs interconnected by a crosspiece, and a mounting plate joined to the shell. The mounting plate has a U shaped configuration to define a longitudinal wall and two flanged portions which extend from the wall in a direction of the shell so that passageways are formed between the legs of the shell and the flanged portions of the mounting plate. A buffer is disposed anteriorly of the cross member and constructed for a snap fit to the mounting plate, with the buffer having spring legs for acceptance in the passageways.

Abstract: In a method of making a motor vehicle part, a metal sheet is hot formed to form a first structural component. Adhesive is applied upon a second structural component, and the first structural component, while still being warm, is joined with the second structural component by effecting an adhesive joint between the first and second structural components as a result of residual heat from the first structural component.
