Electrically length-adjustable steering column for a motor vehicle

Abstract

An adjustable steering column for a motor vehicle may comprise a rotatable steering shaft that has a shaft part that can be displaced axially along its axis of rotation. The shaft part may be rotatably mounted in a jacket tube that is mounted in an axially sliding manner in a guide box held on a retaining part fixed to the vehicle body and can be displaced by means of an electric motor. The adjustable steering column is improved with respect to a small installation space of the electrical adjustment in conjunction with high strength of the steering column. A gear rack may be attached to an outer face of the jacket tube. Also, the electric motor may be fastened to the guide box and may drive a worm gear that protrudes through an opening in the guide box towards the jacket tube and meshes with the gear rack.
