Abstract: A displaceable steering column for motor vehicles may include an actuating unit in which a steering shaft is rotatably mounted. The actuating unit may be displaceable relative to a holding unit in the axial direction of the steering shaft, and optionally in the vertical direction, and can be clamped by means of a clamping device so that the actuating unit is fixed in an non-displaceable manner when the motor vehicle is operating normally. The steering column may also include an energy absorption device disposed between the actuating unit and the holding unit, which in the event of a vehicle crash absorbs at least part of the energy applied to the steering column by material deformation of an energy absorber. The energy absorption device may have a central portion on which an energy absorber is disposed and is engaged with the actuating unit. The central portion may be connected to a clamping portion that can be clamped by the clamping device.

Abstract: A motor vehicle steering system includes a steering wheel hub which has a longitudinal axis and can be attached coaxially on a rotatably mounted steering spindle, and a steering wheel rim which is attached on the steering wheel hub at a radial spacing from the longitudinal axis and extends in a planar manner transversely with respect to the longitudinal axis. The steering wheel rim is mounted on the steering wheel hub in a bearing such that it can be inclined with respect to the longitudinal axis between an operating position and a stowed position about an inclination axis which lies transversely with respect to the longitudinal axis. The steering wheel rim is inclined at a flatter angle with respect to the longitudinal axis in the stowed position than when in the operating position.

Abstract: An adjustable steering column for a steer-by-wire steering device may include an actuating unit that comprises a steering spindle mounted rotatably about a longitudinal axis in a casing unit. The casing unit may have a first casing tube in which a second casing tube is arranged in a rotationally fixed manner with respect to the longitudinal axis and is mounted so as to be movable axially in a telescopic fashion. An actuating drive is connected to the first casing tube and the second casing tube and can move the second casing tube relative to the first casing tube. The actuating drive may comprise a spindle drive with a threaded spindle that is parallel to the longitudinal axis, rotatably drivable by a servomotor, supported on and extending within the first casing tube, and screwed into a spindle nut attached in a rotationally fixed manner to the second casing tube.

Abstract: A steering column may include an adjustment unit with a steering spindle mounted rotatably about its longitudinal axis in a casing tube, a support unit in which the adjustment unit is mounted so as to be adjustable along the longitudinal axis, and a stop device with a movably mounted stop element positionable in a blocking position and a release position. In the blocking position the stop element limits the adjustment travel of the adjustment unit relative to the support unit. In the release position, the stop element allows adjustability in the direction of the longitudinal axis beyond the adjustment travel limited in the blocking position. The stop device has an actuation body that has an inert mass, is actively connected to the stop element, and is mounted movably relative to the support unit. In a crash event, the mass inertia of the actuation body causes it to interact with the stop element to move the stop element from the blocking position into the release position.

Abstract: A steering column for a motor vehicle includes a steering shaft, mounted rotatably about a longitudinal axis in a steering column housing, and a rotation limiter, and has a smooth and quiet construction of the rotation limiter. The rotation limiter includes two oppositely directed flat spiral springs, which are operatively arranged between a coupling part, disposed in a rotationally secure manner on the steering shaft, and the steering column housing.

Abstract: A steering column may comprise an adjusting unit that holds a steering spindle rotatably mounted about a longitudinal axis, a holding unit that receives the adjusting unit, a clamping device that locks the adjusting unit relative to the holding unit in a fixing position and permits adjustment in an unlocked position, and an energy absorption element attached to the adjusting unit and extending through an opening of a wedging housing parallel to the longitudinal axis. The energy absorption element is longitudinally movable in the opening in the unlocked position and lockable within the opening in the fixing position. The opening may have a wedging section with inner wall regions that converge longitudinally. A wedging element is movable into the wedging section and disposed between the energy absorption element and the inner wall regions.

Abstract: A steering column may include an adjustment unit with a steering spindle that is mounted rotatably about its longitudinal axis in a casing tube, a supporting unit that supports the adjustment unit, and a clamping device that controls movement between the adjustment unit and the supporting unit in a longitudinal direction. The clamping device may comprise an actuating element that interacts with a clamping mechanism for clamping the supporting unit to the adjustment unit. The clamping device may further comprise a locking part. In the securing position a form-fitting element of the locking part engages non-displaceably in the longitudinal direction with a form-fitting element of an engagement part connected to the adjustment unit. In the release position the form-fitting element of the locking part may be spaced apart from the form-fitting element of the engagement part to release the adjustment unit. The actuating element may be connected to a lifting mechanism separate from the clamping mechanism.

The tab may be connected to the retaining segment of the steering column jacket along a bending edge. The bending edge may form a projection angle of at maximum 45° with a projected axis of rotation. The free end of the tab is bent around the bending edge towards the axis of rotation.
