A method of connecting two components () is disclosed, wherein a first component () is connected to a second component () at a connecting point () of the first component (), and wherein a surrounding region (), which surrounds the connecting point (), is heated by electrical resistance heating prior to the two components () being connected, so that the ductility of the first component () in the surrounding region () is increased and the strength is substantially reduced.

A vehicle body may include a crossmember and a longitudinal member. The vehicle body helps ensure improved load absorption in collision events with small overlap between the crossmember and another vehicle or object. The deformation capabilities of the vehicle body in collision events involving a full surface area of the crossmember are not substantially impaired. Form-fitting members that comprise connection partners may be provided for the longitudinal member, wherein the form-fitting members ensure that a load path of collision energy is introduced into the longitudinal member selectively in the event of a collision with small overlap. A form-fitting member may form a form-fitting connection in a direction of the longitudinal member in the event of a collision.

One bumper system for a vehicle includes a bumper bracket and a deformation element connected to the bumper bracket. The bumper bracket is composed of a metallic workpiece with an undulating form such that the bumper bracket has at least one undulation trough and at least two undulation peaks, and reinforcement zones are formed in regions of the undulation trough. Another bumper system for a vehicle includes a bumper bracket and a deformation element connected to the bumper bracket. The bumper bracket has an undulating form such that the bumper bracket has a plurality of undulation troughs and a plurality of undulation peaks, and reinforcement zones are formed in each undulation trough. In each system, a second deformation element may be connected to the bumper bracket, and at least one characteristic of the reinforcement zones may increase or decrease between the deformation elements and a middle of the bumper bracket.

Bumper system for a vehicle

The invention relates to a bumper for a motor vehicle, in particular a front bumper, having at least two deformation bodies which are at a distance from one another and of which the center or longitudinal axes, in the mounted state, are oriented substantially parallel to the direction of travel of the motor vehicle, and having a plurality of crossmembers which have a closed profile and which are arranged one above the other and are connected to the deformation bodies. The crossmembers are formed from a group of at least three crossmembers, wherein the respective crossmember of the group has a cross-sectional profile which comprises at least five corners.

A device for absorbing energy in the event of a vehicle collision includes a body component of a motor vehicle, a thrust body for transmitting force, and a metal band for absorbing energy. The body component has a guide for the thrust body, and the body component has a deviating point for the deviating of the metal band. The thrust body has a fastening point for the fastening of the metal band. The metal band is coupled to the deviating point of the body component and to the fastening point of the thrust body such that the metal band is subjected to a tensile load when the thrust body is pushed into the guide of the body component. A distance between the deviating point and the fastening point is selectively adjustable.

The invention relates to a B-pillar reinforcement of a motor vehicle having an upper region for joining the B-pillar reinforcement to the roof region of the motor vehicle and a lower region for joining the B-pillar reinforcement to a floor support of the motor vehicle, which B-pillar reinforcement comprises at least one hollow profile made of metal, in particular steel, and the hollow profile forms the upper and lower regions of the B-pillar reinforcement. The object of providing an improved B-pillar reinforcement which, on the one hand, is optimised in respect of a load-appropriate configuration with a minimum weight, allows a very good integration of additional components of the B-pillar, is achieved in that the hollow profile has at least to some extent a substantially trapezoidal cross-sectional surface in one of the regions and has an at least partly U-shaped cross-sectional surface in the other region.
