Abstract

A steering column for a motor vehicle may include a guide box that accommodates a steering spindle, a bracket for holding the guide box in adjustable fashion on a chassis of the motor vehicle, and a thrust piece through which a clamping shaft extends to fix the guide box relative to the bracket. The thrust piece may be arranged on an outer side of a first side web of the bracket, and the thrust piece may include a dome that extends through a slot of the first side web and serves to generate a force-fitting connection to the guide box.

First claim

What is claimed is:

1. A steering column for a motor vehicle comprising:
a guide box that accommodates a steering spindle;
a bracket for holding the guide box in adjustable fashion on a chassis of the motor vehicle; and
a thrust piece through which a clamping shaft extends, serving to fix the guide box relative to the bracket, wherein the thrust piece is disposed on an outer side of a first side web of the bracket, wherein the thrust piece comprises a dome that extends through a slot of the first side web of the bracket and generates a force-fitting connection to the guide box.

2. The steering column of claim 1 further comprising a clamping plate disposed between the first side web of the bracket and the guide box, wherein the clamping plate generates the force-fitting connection between the dome and the guide box.

3. The steering column of claim 2 wherein the clamping plate is elastic and is elastically deformable by way of the dome.

4. The steering column of claim 2 wherein the clamping shaft extends through the clamping plate.

5. The steering column of claim 2 wherein the clamping plate comprises elevations that protrude from a base surface and generate contact with the guide box.

6. The steering column of claim 2 wherein the clamping plate comprises embossments that protrude from a base surface and generate contact with the guide box.

7. The steering column of claim 2 wherein the clamping plate comprises projections that protrude from a base surface and generate contact with the guide box.

8. The steering column of claim 2 wherein in an unlocked setting a gap exists between at least one of the clamping plate and the bracket or the clamping plate and the guide box.

9. The steering column of claim 2 wherein the clamping plate comprises contact sections that protrude from a base surface and generate contact with the guide box.

10. The steering column of claim 9 wherein a contact point of the dome is disposed in a region between the protruding contact sections of the clamping plate.

11. The steering column of claim 9 wherein a contact point of the dome is equidistant from at least two of the protruding contact sections of the clamping plate.

12. The steering column of claim 1 wherein the thrust piece comprises a roughened inner surface for generating a force-fitting connection to the outer side of the first side web.

13. The steering column of claim 1 wherein the thrust piece comprises engagement elements on an inner surface for generating a form-fitting connection to the outer side of the first side web.
