Adjustment drive for a steering column, and steering column for a motor vehicle

Abstract

An adjustment drive for a steering column for a motor vehicle may include a housing that is able to be connected to the steering column, in which a gear wheel that is able to be rotatingly driven by a motor is mounted in a bearing assembly so as to be rotatable about a spindle axis, and on which a threaded spindle that engages in a spindle nut is axially supported in a direction of the spindle axis. To enable less complexity in manufacturing and assembling, an energy absorbing installation is disposed between the threaded spindle and the housing. When repositioning the threaded spindle relative to the housing in the direction of the spindle axis, the energy absorbing installation is configured to absorb kinetic energy.
