Embodiment Construction

[0020] exist figure 1 The installation position of the impact absorbing element is shown in .

[0021] The impact-absorbing element 1 is located between the impact transverse carrier 3 and the web 5 . The web 5 serves as a flange in order to fasten the absorber element to a longitudinal support of the vehicle, not shown.

[0022] exist figure 2 A side view of the crash-absorbing element along the axis X-X is shown in . The impact-absorbing element 1 in this exemplary embodiment has a longitudinally extending shape that tapers into a cone. In this exemplary embodiment, by way of example, an angle of 3° is given at which the component tapers conically in the direction of the bumper. Here, the tapering of the impact-absorbing element is achieved by a reduction in the outer subregion of the element. In the drawing, this is the uppermost and the lowermost subregion of the component. In contrast, the diagrammatically indicated central region of the crash-absorbing element run...

Abstract

An impact absorbing element comprising a tubular body for absorbing the impact energy in a vehicle is proposed, the impact absorbing element having a double honeycomb-shaped cross section and being configured as a 10-face polygonal line, and honeycomb points being configured which are situated at a spacing (b2) from one another of approximately half the overall height (b1) of the impact absorbing element and define a width.

Description

technical field [0001] The invention is based on a crash-absorbing element composed of a tubular body for absorbing crash energy in a vehicle, the crash-absorbing element having a double-honeycomb cross-section. Background technique [0002] The bumper is arranged transversely at the front and rear of the motor vehicle between a plastic panel closing the body and the frame of the motor vehicle. In order to avoid damage to the vehicle structure in the event of a frontal or rearward collision with low speeds, deformation elements, crash-absorbing elements are integrated. The crash-absorbing element is a thin-walled, usually rectangular element made of steel, aluminum or plastic. The impact-absorbing element can be produced by joining from an extruded metal shell or in one piece, for example as an extruded aluminum profile. [0003] When arranged between the vehicle longitudinal carrier and the bumper transverse carrier, the crash-absorbing element absorbs kinetic energy resu...
