Abstract: The invention relates to a method for producing a material composite composed of metal and plastic to form a plastic-metal hybrid component, in which method, to improve the adhesion of the metal surface and at least one plastic component, stochastically random macroscopic and/or microscopic undercuts are made by means of short-pulse laser radiation in the metal surface in order to roughen it, these undercuts each being filled at least partially with the at least one plastic component in an injection moulding process such that said plastic component engages into the macroscopic and/or microscopic undercuts, wherein, following the roughening of the metal surface and before and/or during the injection moulding process for the at least one plastic component, at least the roughened surface of the metal is heated to a temperature which, during processing, lies in the range of room temperature up to 100° C. above the processing temperature of the plastic.

Abstract: A steering column assembly has a bracket situated fixed on a vehicle, and a rotatable steering column, which has a column jacket and a steering shaft mounted therein. The steering column has modifiable tilt and length and a clamping mechanism for fixing the steering column. The steering column is connected via a bracket slide to a bracket. The bracket slide is displaceably mounted on the bracket, and an energy absorbing element is situated to absorb energy during a displacement of the bracket slide in relation to the bracket.

Abstract: A safety steering column (1) is provided for a motor vehicle, which has a telescopic steering spindle (2) with an upper spindle part (3) which is near to the steering wheel and a lower spindle part (4) which is remote from the steering wheel, and is rotatably mounted in a jacket tube (5). The jacket tube (5) is of telescopic design and has an upper tube part (6) which is near to the steering wheel and a lower tube part (7) which is remote from the steering wheel, the lower tube part (7) being mounted so as to be pivotable about a first axis (10) on a bracket (9) which can be arranged fixed to the vehicle. In addition, an adjustment device which serves to vertically adjust the safety steering column (1) and has an actuating element (12) which is mounted so as to be pivotable about a second axis (14) is provided.

Abstract: A steering column arrangement includes a bracket which is arranged fixedly on the vehicle, a steering column which has a casing tube and a steering spindle which is mounted rotatably therein, the steering column being configured so as to be adjustable in its inclination and length, and clamping device(s) being provided for fixing the steering column. In order to increase the safety of vehicle occupants, the steering column with the clamping device(s) is connected to the bracket via a bracket slide which is mounted displaceably on the bracket, it being possible for the bracket slide to be displaced relative to the bracket only after a predetermined force which is applied to the steering column in the axial direction is exceeded, and the predetermined force being smaller than a force which may be absorbed by the clamping device(s).

Abstract: In a steering column arrangement having a bracket which is arranged fixedly on the vehicle, a steering column which has a casing tube and a steering spindle which is mounted rotatably therein, the steering column is configured so as to be adjustable in its inclination and length, and clamping device(s) are provided for fixing the steering column. In order to configure the steering column to be safer while maintaining comfort functions, the steering column is connected with the clamping device(s) to the bracket via a bracket slide which is mounted displaceably on the bracket, and locking device(s) being provided between the bracket slide and the bracket.

Abstract: A steering column arrangement has a console arranged fixedly with respect to the vehicle and a steering column which has a steering column tube and a steering spindle mounted rotatably in the latter. The steering column is designed to be variable in its inclination and length, and a clamp for securing the steering column is provided. In order to increase the safety of the vehicle occupants, while at the same time maintaining known comfort functions, and to ensure a reliable use of the steering column arrangement, it is proposed to connect the steering column to the console by the clamp via a console slide which is mounted displaceably on the console. Furthermore, an actuation element operatively connected to the clamp is provided for releasing and locking the clamp, and the operative connection is releasable.

Abstract: A vehicle steering column consists of an inner steering column element, an outer steering column element and a sliding bush arranged therebetween. The sliding bush is fixedly connected to the outer steering column element by plastic, which is injection molded into depressions on the outer circumferential surface of the sliding bush.

Abstract: The invention relates to a clamping device (1) for the steering column of a motor vehicle, said device (1) comprising two jaw-shaped components (2, 3) running vertically parallel to one another, between which a casing tube of the steering column extends and which have two opposing through-openings (7). The device (1) further comprises a clamping bolt (6), which passes through the through-openings (7) and interacts by tensioning with a counter-element (8) in order to apply the clamping force, the bolt head being arranged on sides of the exterior (10) of the one jaw-shaped component (2) and the counter-element (8) on sides of the exterior (11) of the other jaw-shaped component (3).

Abstract: An adjustable steering spindle for a motor vehicle includes a steering spindle hub and a steering spindle shaft. The steering spindle shaft is moveably mounted in the steering spindle hub in the axial direction, and the steering spindle hub is rigidly connected to the steering spindle shaft rotationally. The spindle further includes a locking device that limits shape-lockingly an axial movement of the steering spindle shaft in the spindle hub, which movement elongates the steering spindle in the axial direction.
