Abstract: A steering column for motor vehicles with axially adjustable steering shaft and positive locking between an axially adjustable, non-rotatably mounted steering column jacket and a support bearing that forms a rigid part of the vehicle body is described, wherein the locking mechanism consists of teeth provided on the circumference of the steering column jacket and teeth engaging in same, which latter teeth are provided on a locking element movably anchored in the support bearing, as well as of wedge bodies which can be moved into a locked position that brings about locking.

Abstract: A steering column for motor vehicles with a steering shaft that is movable in the axle direction and held by a positive connection notching. The notching is formed between a jacket barrel (1) placed so that it is fixed from turning, and a solid body thrust bearing (2) and consists of toothed gearing segments (4, 5) on the width of the jacket barrel (1) and anchored toothed elements (6, 7) that are movable on the thrust bearing (2) with at least a gear tooth (9, 10). Wedge bodies (11, 12) are provided that by means of a control are movable in the bolt position brought about by the notching. The gearing tooth portions on the jacket barrel (1) include at least two segments (4, 5) developed with the same tooth spacing, that nevertheless are arranged around a half gear segment displaced with respect to each other.
