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.

A steering device includes an inner column, an outer column, a hanger bracket, and a fixing member. The hanger bracket has a guide hole which extends in the front-rear direction and through which the shaft portion of the fixing member passes. An edge portion of the guide hole is provided with a first region with which the seat portion of the fixing member comes into contact to fix the hanger bracket to the inner column and a second region which is disposed in front of the first region and faces the seat portion when the seat portion is displaced forward together with the inner column by a secondary collision load being input. A frictional restraining force between the seat portion and the edge portion of the guide hole in a state where the seat portion is displaced to a position opposite the second region is set to be smaller than a frictional restraining force between the seat portion and the edge portion of the guide hole at a position where the seat portion faces the first region.

A feedback actuator for a steering device of a motor vehicle may include a casing unit that has an outer casing that can be attached to a motor vehicle and an inner casing received therein such that the inner casing is telescopically adjustable in a longitudinal direction, a steering spindle mounted in the inner casing such that the steering spindle is rotatable about a longitudinal axis, and an electric motor of a drive unit arranged in an interior space of the casing unit. The electric motor may have a stator that is fixed on the outer casing and a rotor that can be driven rotationally. A rotor shaft may be coaxial with respect to the longitudinal axis and coupled via a gear mechanism to the steering spindle.

A steering column that is adjustable by a motor may include a supporting unit that is attachable to a vehicle body, an actuating unit held by the supporting unit, a steering spindle mounted in the actuating unit rotatably about a longitudinal axis, an adjusting drive for adjusting the actuating unit relative to the supporting unit via a threaded spindle and spindle nut, and a drive unit by which the threaded spindle can be driven rotationally relative to the spindle nut. To improve compactness and greater structural freedom, the drive unit may be connected via a flexible drive connection to a gear unit that can be moved spatially relative to the drive unit.

A steering column may include a first adjustment drive for adjustments in a length adjustment direction and a second adjustment drive for adjustments in a height adjustment direction. The adjustment drives each have a drive motor. A joint control unit for the drive motors comprises three half bridges arranged in parallel and connected between two voltage potentials. Each half bridge has a high-side switch and a low-side switch connected in series via a connection point. The connection point of the first half bridge is electrically conductively connected to a first connection of a first drive motor. The connection point of a second half bridge is electrically conductively connected to a second connection of the first drive motor and to a first connection of the second drive motor. The connection point of a third half bridge is electrically conductively connected to a second connection of the second drive motor.
