Embodiment Construction

[0026]FIG. 1 shows a schematic perspective view of an impact-absorbing system 1 . The impact-absorbing system 1 comprises a vehicle structure 2, a web 2a and a bumper arrangement 2b. Between the connecting plate 2 a and the bumper arrangement 2 b is arranged a crush can or a crush can arrangement 3 , wherein these components are shown only connected to the bumper arrangement 2 b. The crush can device 3 comprises a deformable part 4 configured as a compressible tube and a seat part 5 formed as a web. Furthermore, the crush can device 3 comprises impact limiting means, not shown here, which are connected to the bumper device 2b. The support part 5 of the crush can device 3 can be connected to the connecting plate 2a by fasteners. The seat part 5 comprises a holding area 6 in which the central deformable part 4 is in a fixed position in the normal position / situation. Two guide regions 7 extend laterally therefrom, namely a first guide region 7a and a second guide region 7b. A...

Abstract

The subject matter of the present invention relates to a crashbox apparatus (3) and to an impact absorption system (1) with a crashbox apparatus (3), in particular for a motor vehicle, for absorbing impact forces, comprising: a deformable element (4) for absorbing an impact force, which acts in a main direction, by corresponding deformation and / or a damping movement, an impact-limiting device (9) which is connected to the deformable element (4) at an end region, a support element (5) which is connected to the deformable element (4) at another end region, preferably the other end region lying opposite the first end region and is intended for holding the deformable element (4) and for connecting it to further components, and connecting means for connecting the deformable element (4) to the impact-limiting device (9) and / or to the support element (5), wherein the connecting means have at least one retaining region (6) for retaining the deformable element (4) and, branching off from said region, at least one guide region (7) which, in the event of an impact, permits a movement of the deformable element (4) from the retaining region (6) along the guide region (7) in a secondary direction deviating from the main direction.

Description

technical field [0001] The invention relates to a crush can arrangement according to the subject-matter of claim 1 or the subject-matter of claim 9 and to a shock-absorbing system having a crush can arrangement. Background technique [0002] The crush box device, or shock absorbing system, is used in almost all automobiles to reduce the impact of a crash in the event of an accident, thereby minimizing repair costs and protecting passengers. The crush can assembly is typically connected to a cross member attached to a bumper or bumper assembly, or to a vehicle frame or vehicle structure. In the event of a collision impacting the outside of the bumper, the crush box arrangement prevents substantial damage to the vehicle frame. The cross member and the frame are designed to be highly rigid, so that no energy is absorbed in minor collisions by plastic deformation on the secondary supports or in the frame. This can be achieved because the impact energy is absorbed by the impact...
