The invention relates to a steering column assembly that can be shortened by the effect of an impact while absorbing energy. In order to increase the safety for vehicle occupants, the steering column comprises a crash element (5) with an adjustable energy absorption level. The crash element (5) has an energy absorbing element (8) and a deforming element (6). In the event of an accident, the energy absorbing element (8) moves while bending and bending back relative to the deforming element (6). The energy is absorbed by the deformation. A change in the alignment of the deforming element (6) alters the resistance that the deforming element (6) presents to the energy absorbing element (8) during the relative movement. This enables the degree of energy absorption to be adjusted. |
