Abstract

A motor vehicle steering column includes an inner jacket pipe that receives a steering spindle, which is received in a longitudinally adjustable manner in an outer jacket pipe held on a steering console and having a hollow cross-section. The steering column also includes a clamping device, by means of which the inner jacket pipe can be releasably secured in its adjusted longitudinal position relative to the outer jacket pipe. The outer jacket pipe has a recess at least over a longitudinal region, whereby its hollow cross-section can be altered by the clamping device.

First claim

The invention claimed is:

1. A motor vehicle steering column, comprising:
a steering spindle;
an inner jacket pipe that receives the steering spindle;
an outer jacket pipe that receives the inner jacket pipe in a longitudinally adjustable manner in the outer jacket pipe, wherein the outer jacket pipe is held on a steering console and has a hollow cross-section;
a clamping device configured to releasably secure the inner jacket pipe in an adjusted longitudinal position relative to the outer jacket pipe,
wherein the outer jacket pipe has a recess, at least over a longitudinal region, which allows the hollow cross-section of the outer pipe to be altered by the clamping device; and
a clamping plate arranged between a clamping element of the clamping device and the outer jacket pipe,
wherein the clamping plate is coupled for movement with the inner jacket pipe via a driver connection that pushes through the outer jacket pipe.

2. The steering column of claim 1 , wherein the recess is open towards a steering wheel side of the outer jacket pipe.

3. The steering column of claim 1 , wherein the recess is a slot running in the axial direction of the outer jacket pipe.

4. The steering column of claim 1 , wherein the clamping device comprises a wedge clamping device.

5. The steering column of claim 1 , wherein the clamping plate is connected positively or firmly bonded to the inner jacket pipe via the driver connection.

6. The steering column of claim 1 , further comprising:
a longitudinal hole for the driver connection is hollowed out of the outer jacket pipe.

7. The steering column of claim 1 , further comprising:
at least one friction-increasing element allocated to the clamping device.

8. The steering column of claim 1 , wherein the outer jacket pipe is held on the steering console in a height-adjustable manner.
