Embodiment Construction

[0016] figure 1 An exemplary embodiment of the bumper system (1) according to the invention is shown in perspective. The bumper system comprises at least one bumper bracket (2) made of metallic material, in particular of high-strength steel material, preferably of hot-formed steel and correspondingly (press) hardened steel material, said bumper bracket has an undulating cross-section or body structure, wherein said undulating shape (3) is such that said bumper bracket (2) has at least one, in this case two undulating valleys (4) and at least two, in this case Below is an example of three undulating peaks (5). Furthermore, on the left-hand and right-hand sides of the bumper bracket (2), there are provided deformation elements (6) which can be connected to longitudinal beams (not shown) of the vehicle body by preferably detachable threaded connections (14). The deformation element (6) is assembled from eg at least two half-shells (7, 8), preferably formed of steel material and...

Abstract

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.

Description

technical field [0001] The invention relates to a bumper system for a vehicle comprising a bumper carrier made of a metal part having a wave-shaped cross-section, wherein the wave-like form is such that the bumper carrier has at least one an undulation trough and at least two undulation peaks, and including at least one deformation element connected to said bumper bracket. Background technique [0002] Bumper systems, in particular in the front end structure of a vehicle, in particular in motor vehicles, must meet high demands with regard to the safety of the vehicle occupants as well as with regard to weight and ease of replacement in the event of damage. In the event of a front-end collision, this is possible by means of a targeted modification of the bumper bracket and the deformation element, preferably in the form of a so-called crash box and which is preferably arranged on the longitudinal beam of the vehicle Between the bumper bracket and the further, in particular l...
