Longitudinal adjusting arrangement on a casing tube telescope of a steering spindle in a motor vehicle
First Claim
1. Longitudinal adjusting arrangement on a casing tube telescope of a steering spindle in a motor vehicle, which has a spindle drive which has a threaded spindle extending in a longitudinal direction outside on the casing tube, which threaded spindle is supported on a first telescope section and, by means of its thread, engages in a spindle nut which is supported on a second telescope section arranged coaxially with respect to the first telescope section,wherein at least one energy absorption element is fixed on one of the telescope sections, said energy absorption element being acted upon by at least one of the threaded spindle and the spindle nut in response to axial movement of the threaded spindle with respect to the spindle nut.

Abstract
Longitudinal adjusting arrangement on a casing tube telescope of a steering spindle in a motor vehicle comprises a spindle drive which has a threaded spindle extending in the longitudinal direction outside on the casing tube. The threaded spindle is supported on a first telescope section and, by means of its thread, engages in a spindle nut which is supported on a second telescope section arranged coaxially with respect to the first telescope section. In order to be able to reduce impact energy in this longitudinal adjusting arrangement in the case of a crash, at least one energy absorption element is fixed on at least one of the telescope sections, which energy absorption element, in the case of a movement, particularly an axial movement of the threaded spindle and/or of the spindle nut relative to the respective supporting telescope section, is acted upon by at least one of these parts of the spindle drive.

7. A vehicle steering assembly comprising:
-
a steering spindle, a telescope casing having first and second concentric telescopic casing tubes surrounding the steering spindle, a longitudinal adjusting device interposed between the first and second casing tubes at a position on radially outwardly facing surfaces of the casing tubes and at least one energy absorption element fixed on one of the casing tubes at a position to be acted on by at least one movable part of the longitudinal adjusting device. - View Dependent Claims (8, 9, 10, 11)
