Abstract

See full text

A length-adjustable steering shaft may include a metallic hollow shaft with an opening in which a metallic inner shaft is accommodated rotatably-fixedly and in an axially movable manner. The steering shaft may also include a pull-out retention means with an outer stop that protrudes into an opening of the hollow shaft and an inner stop that protrudes outward from the inner shaft. The inner and outer stops may be formed from the metallic material of the hollow shaft or the inner shaft and may comprise stop surfaces that are directed toward each other in an axial direction. A layer of non-metallic material may be applied to at least one of the inner stop or the outer stop at least partially in a region of the stop surface.
