  • Device for locking the rotational movement of a steering column of a motor vehicle
    Patent number: 4570468
    Abstract: The invention relates to a device for locking the rotational movement of a steering column of a motor vehicle by means of a clamp locking mechanism with rollers (4) parallel to the axis, which rollers clamp the steering column in both rotational directions between a cylindrical track and clamping surfaces oblique to the track and are guided in a coaxial cage rotatable about the steering column. The cage can be carried along by the steering column in both rotational directions in each case into one of the two clamping positions and can be fixed in a central position located between the two clamping positions, in which central position the rollers release the steering column. All the rollers (4) are surrounded externally by at least one elastic ring (6) coaxial to the column (1), which ring elastically loads the rollers towards the steering column.
