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. In addition, each segment is adjoined around a traverse axis (8) movable placed notch element (6, 7) whose gear teeth are spaced a distance from each other in the axle direction of the jacket barrel (1) that corresponds to a direct multiple of the spacing of the toothed gear segment.
