Abstract

A plug-on body for a clamping bolt of an adjustable steering column for a motor vehicle. The plug-on body includes at least one opening for guiding the clamping bolt through the opening of the plug-on body and at least one or two damped elongated hole stops for damping an impact of the clamping bolt on an end of an elongated hole.

First claim

The invention claimed is:

1. A plug-on body for a clamping bolt of an adjustable steering column for a motor vehicle, the plug-on body comprising:
an opening for guiding the clamping bolt through the opening;
a damped elongated hole end stop for damping an impact of the clamping bolt on an end of an elongated hole; and
a cam carrier damper for damping a turning movement between a first cam carrier of the steering column and a further cam carrier of the steering column.

2. The plug-on body as in claim 1 , further comprising a guidance face for sliding along a side wall of the elongated hole.

3. The plug-on body as in claim 1 , further comprising a stroke end stop for delimiting a shifting movement of the plug-on body along the clamping bolt.

4. The plug-on body as in claim 3 , wherein the stroke end stop is developed as a portion of a resilient tongue.

5. The plug-on body as in claim 1 , further comprising a detent for snapping in the plug-on body on one of the cam carriers.

6. The plug-on body as in claim 1 , wherein the plug-on body further comprises a synthetic material, or wherein the plug-on body is implemented with a synthetic material.

7. The plug-on body as in claim 1 , wherein the plug-on body is developed unitarily as one piece.

8. An adjustable steering column for a motor vehicle, comprising:
a clamping bolt; and
a plug-on body as in claim 1 , wherein the clamping bolt is guided through the opening of the plug-on body and the elongated hole end stop is disposed in an elongated hole of the steering column and the cam carrier damper is disposed or acts between a first cam carrier of the steering column and a further cam carrier of the steering column.

9. The adjustable steering column as in claim 8 , wherein the plug-on body is supported shiftably in the longitudinal direction of the clamping bolt thereon or is supported turnably in a circumferential direction of the clamping bolt thereon.

10. The adjustable steering column as in claim 8 , wherein the first cam carrier or the further cam carrier comprises cams being disposed in an annulus and cooperating with one another, and the cam carrier damper is disposed within the annulus.
