Abstract: A motor vehicle steering column with a positioning device (1) is provided as well as a positioning device for motor vehicle steering columns.

Abstract: At least one first mounting part (1), which has at least one passage opening (1a) for guiding a connector (3). The connector connects to one another at least two clamping parts (4, 7) that are movable in relation to one another, which clamp the connecting piece (2). The connector (3) and the clamping parts (4, 7) form a first clamping mechanism. Structure is provided for securing the first clamping mechanism, and includes a second clamping mechanism (10, 11), which is located between the clamping parts (4, 7) of the first clamping mechanism and is coupled with same. The second clamping mechanism has at least one second mounting part (1), which has a passage opening (11a) that is at least congruent with the passage opening (1a) of the first mounting part (1), as well as a spindle (10), which is connected with the first clamping mechanism (3, 4, 7) via a clamping part (4) of the first clamping mechanism (3, 4, 7).

Abstract: A tilting pin mechanism is provided, preferably for the clamping device of a motor vehicle steering column, whose position is adjustable, for detachably fixing a housing accommodating the steering column at a bracket that is a rigid part of the body. The housing and the bracket have at least one cooperating friction surface pair that can be pressed against each other by means of the tilting pin mechanism. The tilting pin mechanism includes a centrally arranged bolt which is displaceable in the direction of its central longitudinal axis and with at least one tilting pin whose longitudinal axis is arranged approximately in parallel to the central longitudinal axis of the bolt. The tilting pin is supported on one side directly or indirectly at a bolt collar and is accommodated at its other end in a recess on the front side of an actuating ring.

Abstract: A locking device for two components of a height- and tilt-adjustable motor vehicle steering column, that has components that are displaceable in relation to one another, is disclosed. One component is fixed on a bracket stationarily connected to the body of the motor vehicle and the other component is part of a steering column housing accommodating the steering column, with at least two toothed surfaces each fixed on the components that are displaceable in relation to one another. The toothed surfaces have each at least one row of teeth with a plurality of teeth arranged next to one another. The free tips of the teeth of the two rows, which free tips face one another, are mutually repelled by magnetic forces.

Abstract: A fastening system for fixing a first assembly unit to a second component for use especially in the motor vehicle industry is presented, which has at least one fastening screw, a corresponding first preassembly thread on the first assembly unit, in which the fastening screw is fixed after the preassembly, and a fastening thread on the first assembly unit or on the second component for fixing the first assembly unit to the second component by means of the fastening screw. The fastening screw has at least two threaded areas for preassembly and for fastening with different thread pitches, wherein the preassembly thread and the fastening thread as well as the threaded areas are provided with different pitches and the second threaded area, which is used for fastening and is facing away from the screw head, has a smaller diameter than the threaded area that is used for the preassembly and is adjacent to the screw head.

Abstract: A process is disclosed for fixing a motor vehicle steering column. The, motor vehicle steering column is adjustable in the axial and/or vertical direction and has a steering shaft and a housing accommodating the steering shaft, on a bracket of the steering column of the motor vehicle, which bracket is a rigid part of the body. In the case of an accident, a positive-locking connection is established by pyrotechnical device between the adjustable steering column housing and the bracket of the steering column, at the moment of the impact of the motor vehicle against an obstacle. A device for carrying about the above-mentioned process is disclosed, in which at least one pyrotechnical module and at least one element, which can be controlled by the pyrotechnical module, are present for the positive-locking connection between the steering column and the bracket, which is a rigid part of the body.

Abstract: A fastening system is provided for fastening a first structural component to a second structural component for use especially in the motor vehicle industry, which has at least one fastening screw, a corresponding first preassembly thread on the first structural component, in which the fastening screw is fastened after the preassembly and a fastening thread on the first structural component or the second structural component for fixing the first structural component to the second structural component by the fastening screw, whereby this screw, after fixing, is fastened in the associated fastening thread, whereby the fastening screw has at least one front threaded area arranged on the free end of the screw shank and a second area adjacent to the screw head, whereby this is provided with a plastic coating, into which a thread corresponding to the preassembly thread is incorporated only when the fastening screw is screwed into the preassembly thread.
