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 sleeve of a steering column includes (i) an outer tube and an inner tube that are movable relative to each other, and (ii) an adjustment system. The adjustment system includes a screw for adjusting the axial position along an adjustment axis constrained to move in translation with a first of the two elements by at least two guide bearings for rotationally guiding the adjusting screw about the adjustment axis. At least one of the bearings supporting the adjusting screw is a guide bearing with axial force take-up for blocking the translational movement of the adjusting screw.

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.

The steering column further includes a steering member on which a vehicle steering wheel is mounted. The steering member includes a transmission shaft mounted so as to rotate with respect to the support base about a longitudinal main axis. The steering column also includes at least one force sensor that is interposed between a first non-rotating element of the steering column and a second non-rotating element belonging either to the steering column or to the chassis of the vehicle.

Abstract: An absorber of steering column shock energy includes a plastically deformable part forming a loop, a breakaway link closing this loop on itself, and a first attachment interface and a second attachment interface separate from the breakaway link and arranged on either side of the loop. The part and the fusible link are arranged so that the exertion of forces in opposite directions on the first attachment interface and on the second attachment interface respectively, causes a stress leading to a deformation of the loop, breaking of the breakaway link and further deformation of the loop after this break.

A support made as two parallel vertical members mountably fixed on a vehicle body mount the steering column axially between them. The body-tube has reinforcement members on two opposite sides. An attaching device compresses the reinforcement members in the support with a tightening non-rotatable bolt extending axially through the body-tube reinforcement members and the support members. A nut on one end of the bolt is tightened by an operator for establishing a determined level of a frictional force between the support and body tube.

A second of the two elements has an end of the rectilinear length portion of the wire secured thereto. The turns of the coil winding are deformable and unwind about the axis to absorb energy of a force applied in a direction parallel to the rectilinear relatively separating apart the two elements.
