ABSTRACT:
A locking device for locking an adjustable steering column in an adjusted position including a lateral clamping element having enlarged heads at opposite ends thereof and a piston and a cylinder between the enlarged heads and a rotatable locking rod for locking or unlocking the steering column arranged axially immovable relative to the steering column and compactly in a space that is little used. The piston and cylinder have overlapping bores parallel to the centerline of the steering column. The locking rod, also parallel to the centerline of the steering column, has an oval-shaped portion protruding through the overlapping bores so that when the long axis of the oval-shaped portion is vertical the clamping element is loose and the steering column is vertically and horizontally adjustable and when the long axis of the oval-shaped portion is horizontal the clamping element is tight and the steering column is vertically and horizontally locked.
