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.
