Embodiment Construction

[0045] figure 1 A perspective view of a safety steering column 10 for a vehicle is shown, which is formed as an angled steering column with two universal joints 11 , 12 . With regard to these universal joints 11 , 12 , the safety steering column 10 can be divided into three steering column parts 13 , 14 , 15 which remain rigid themselves during normal operation of the vehicle. The crushing elements 1 are provided on the first steering column portion 13 and extend in the axial direction A; so constructed that in the event of a frontal collision, the crushing elements 1 are sequentially compressed first and then folded, thereby preventing the safety steering column 10 from breaking down. Parts penetrate the cockpit of the vehicle. When the axially acting threshold force F (more precisely the figure 2 , 5 and 6) act on the crush element 1 and thus on the crush portion 4, compressing and collapsing begins. The crush element 1 is here connected, preferably bolted, to the adjac...

Abstract

The invention relates to a crush element (1) for a safety steering column (10). In order to provide a reliable, structurally simple safety steering column, it is provided according to the invention that the crush element has a first and a second connecting parts (2, 3), and the crush element (1) has a perforated crush deformable by an axially acting threshold force (F) arranged between the first and second connecting parts (2, 3) The crushing part (4) and the connecting parts (2, 3) are resistant to deformation with respect to the threshold force (F), wherein the crushing element (1) is integrally made of metal by additive manufacturing, and wherein the first connecting part (2 The end region (2.4) of ) facing the collapsed part (4) has a first part (2.6) protruding axially relative to the second part (2.7), the first part (2.6) is opposite to the second part (2.7) The axial direction (A) is transversely opposite.

Description

technical field [0001] The present invention relates to a crush element for a safety steering column. Background technique [0002] Motor vehicles use safety steering columns to increase driver safety in the event of a frontal collision. The safety steering column prevents parts of the steering column, in particular the steering wheel, from being pushed into the cockpit. It is known to use various generally passive mechanical means to achieve this. One approach is to configure the steering column as a telescoping steering column, wherein one portion of the steering column engages another portion of the steering column, and upon exceeding a predetermined threshold force, one portion of the steering column can be pushed telescopically into the other portion, thereby Reduce the overall length of the steering column. The two parts may be connected together, for example, by a connecting element designed to yield when a threshold force is exceeded. [0003] Alternatively or ad...
