A crossmember for a bumper includes an extruded profile base frame with at least two connecting areas, for attaching the crossmember to a vehicle structure, and which are set at a distance from each other along a longitudinal direction. An extruded reinforcing element is fixedly secured to a rear side of the extruded profile base frame between the at least two connecting areas. The crossmember is weight-optimized and which can be produced in a cost-effective manner.

Crossmember and method for manufacturing a crossmember

A method of making a beam-box crash management system comprises forming a first shell () from a first sheet metal blank by a hot forming process. The first shell has a high tensile strength beam portion () and integrally formed there-with a first low yield strength crash box portion () proximate a first end of the beam portion and second low yield strength crash box portion proximate a second end of the beam portion. The first shell also has an open face extending continuously along the beam portion and each of the first and second crash box portions (). A closing element () is formed from a second sheet metal blank, and is fixedly secured adjacent to the open face of the first shell.

Bumper assembly

A crash box includes a body portion extending from a top edge to a bottom edge along a global z-axis (A) and having a pair of side walls disposed in spaced relationship to one another. At least one x-shaped reinforcing web extends between the side walls along a plane (P) disposed transverse to the axis (A). An extension portion is integral with the body portion and extends outwardly from one of the side walls and is disposed along the plane (P). A flange plate is also integral with the body portion and defines at least one flange plate attachment hole for securing the crash box to a frame of a vehicle.

Crash box for a bumper assembly

A method of making a beam-box crash management system comprises forming a first shell () from a fist sheet metal blank by a hot forming process. The first shell has a high tensile strength beam portion () and integrally formed there-with a first low yield strength crash box portion ()proximate a first end of the beam portion and second low yield strength crash box portion proximate a second end of the beam portion. The first shell also has an open face extending continuously along the beam portion and each of the first and second crash box portions (). A closing element () is formed from a second sheet metal blank, and is fixedly secured adjacent to the open face of the first shell.

The present invention relates to an energy absorption device () for a bumper arrangement of a vehicle, with a hollow longitudinal section () intended for deformation, a rolled-back region () adjoining the hollow longitudinal section, and an extension section () connected to the rolled-back region. In order to improve an energy absorption device of this type to the extent that obliquely acting accident forces can be absorbed with a high degree of efficiency in as simple a manner as possible, it is proposed, in an initial state prior to energy absorption, to orient the hollow longitudinal section () obliquely with respect to the axial direction of the extension section ().
