Abstract
Abstract A telescopic safety steering column for motor vehicles with a steering wheel displaceable relative to the outer column under energy absorption and with an energy-absorbing connection of the outer column with a front part of the vehicle; the energyabsorbing connection of the outer column with the front part of the vehicle is relatively soft in bending in the direction of an impact of the driver against the steering wheel and is constructed relatively form-stable in the opposite direction by the use of a structural part stressed in tension.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
135 words
A telescopic safety steering column for motor vehicles which includes an outer column means, a steering wheel displaceable relative to the outer column means under energy absorption, the improvement comprising an energy absorbing connection means for connecting the outer column means with a front part of the vehicle, said energy-absorbing connection means from the outer column means to the vehicle front part being relatively soft in bending in the impact direction of a body, said energy-absorbing connection means including a structural member stressed in tension so as to render said energy-absorbing connection means form-stable in an opposite direction, and a vehicle cross bearer means provided with notch means, said notch means being covered off on the outside by said structural member, said structural member being composed of a material having a relatively high tensile strength.
