Abstract
A steering device for motor vehicles, which is adjustable along its longitudinal axis and whose steering column can be telescopically extended and retracted by means of a drive device, the steering column jacket being designed in several parts, one steering column jacket part being fixed to the body and one steering column jacket part being movable relative to the first, and in which adjustment can be introduced into the steering column jacket movable part by means of a coupling element with which a worm gear driven by a drive motor engages. The coupling element consists of a toothed rack located on the periphery of the steering column jacket movable part, a worm gear located with its axis parallel to the rack engaging with the rack and passing through a recess in the steering column jacket fixed part. The engagement angle of the worm gear is so dimensioned that self-locking occurs.
