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.

Crash box and bumper for a motor vehicle

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.

Bumper for a motor vehicle

A crash box for installation between a longitudinal member and a bumper cross member of a motor vehicle, includes a sheet metal body having a deformation member which extends anteriorly of an end surface of the longitudinal member and whose maximum crumpling capability defines the energy absorption of the crash box. In prolongation of the deformation member is an attachment member which is engaged in the longitudinal member and detachably secured by bolts therein. Formed in a transition zone between the deformation member and the attachment member, is a stop which is configured in the form of an outwardly directed material protuberance or outwardly directed thickened area of the sheet metal body and bearing against the end surface of the longitudinal member.

Crash box

A bumper for a motor vehicle, includes a cross member for attachment to longitudinal members of a vehicle chassis. The cross member is defined by a length and has a shell element extending over a major part of the length of the cross member, wherein the shell element has incorporated therein at least one deep-drawn reinforcement member of cup shape configuration.

The deformation member ( ) is disposed between a longitudinal member ( ) and a cross member ( ) of a motor vehicle, with the cross member having a horizontal central longitudinal plane which is vertically offset to the horizontal central longitudinal plane of the longitudinal member ( ). The deformation member includes an elongate, hollow base body ( ) of polygonal cross section and a height which is greater than its width, and an upper and a lower reinforcing shell ( ) which are connected through welding to the base body ( ) via the longitudinal edges of their legs ( ). The end walls of the lower reinforcing shell ( ) are closed by cover plates ( ). The deformation member ( ) can be coupled via a plate ( ) with the longitudinal member ( ) of the motor vehicle.

Deformation member

A bumper for a motor vehicle has a transverse support and impact damping members connected to the transverse support, wherein the transverse support is fastened transverse to longitudinal supports of a motor vehicle frame via the impact damping members to the longitudinal supports. The transverse support is an open profiled member opening in a direction toward the impact damping members and has an upper shell and a lower shell. The transverse support has a front stay with an upper longitudinal edge and a lower longitudinal edge, wherein each one of the upper and the lower longitudinal edges has a leg extending toward the impact damping members. Each leg has a vertical portion and an angled reinforcement flange pointing toward the vehicle frame. Each leg is slanted inwardly between 5 degrees and 45 degrees from the longitudinal edges to the vertical portions.
