PCT No. PCT/EP83/00039 Sec. 371 Date Nov. 9, 1983 Sec. 102(e) Date Nov. 9, 1983 PCT Filed Feb. 18, 1983 PCT Pub. No. WO83/03082 PCT Pub. Date Sep. 15, 1983.A device for blocking the rotary movement of a steering column of a motor vehicle by means of a clamping lock acting in the two directions of rotation and having two sets of axis-parallel rollers which are guided in respective coaxial cages rotatable about the steering-column axis. The rollers of each set are clamped between a cylindrical running track and associated clamping surfaces inclined relative to the running track in a first position of the cage and run freely in a second position, one cage (9) with its rollers (7a) between the running track and the clamping surfaces serving for blocking the first direction of rotation, and a second cage (10) with its rollers (7b) serving for blocking the second direction of rotation. The two cages (9,10) are rotationally adjustable in opposite directions.
