Abstract: A steering column sleeve includes two elements made up of an outer tube and an inner tube, and a system for adjusting a resistive force against a relative translational movement between the elements. A friction pad is supported by a first of the elements, and a clamping surface is rigidly connected to a second of the elements, wherein the friction pad is configured to contact and bear on the clamping surface, and an adjustment mechanism. The adjusting mechanism includes a cam bearing on a support member to generate a variation in pressure of the friction pad on the clamping surface parallel to a reference axis that is fixed relative to the first element, between a use position and an adjustment position. The adjustment mechanism of the adjustment system is configured to generate a relative rotational movement between the cam and the support member about the reference axis.

Abstract: A steering column sleeve includes (i) a translationally movable outer tube and inner tube, and (ii) an adjusting system for adjusting the relative position of the tubes. The adjusting system includes a screw for adjusting the axial position of the two elements. The adjusting system further includes an adjusting device for adjusting a resistance force opposing the relative movement between the tubes. The adjusting device has a friction pad and a clamping surface against which the friction pad moves between operating and adjustment positions. The adjusting system also includes a kinematic chain so that, beyond a threshold resistance torque transmitted by the screw to a single motor that it drives, its torque is transmitted to the adjusting device so as to move the friction pad from its operating position to its adjustment position.
