Abstract: A motor vehicle steering column unit with a steering column housing and a steering column arranged therein and with an electrically driven adjusting device is disclosed for the longitudinal adjustment and for the tilt adjustment of the steering column. The adjusting device has only one electric drive unit for the rotary drive of an adjusting spindle, as well as at least two spindle nuts, which are arranged on the adjusting spindle and are mounted movably in the axial direction of the adjusting spindle. At least one adjusting mechanism each for the longitudinal movement and for the tilting movement, as well as one switching device for each direction of movement is provided. A nonpositive connection can be established between the respective switching device and the spindle nut located adjacent to the switching device.

Abstract: The present invention pertains to a safety system for steering shafts, in which shaft parts non-rotatably engage each other and are secured against relative displacement in relation to one another by injected shear materials, which are designed for maximum axial forces in the steering shaft and engage recesses on the outer circumference of the inner shaft part and on the inner circumference of the outer shaft part. Such a safety system has an at least double telescoping shaft system, in which at least two shaft parts are connected to one another by an intermediate shaft part, and the inner shaft parts engage a radial expansion of the corresponding outer shaft part, and a cross section of the shear material designed for shearing is arranged between the shaft parts in the area of the expansion.

Abstract: An adjustable steering column for motor vehicles, in which a steering axle (2), which is composed of parts that are telescopingly displaceable in relation to one another and is connected at its top end (3) to the steering wheel, is rotatably mounted in a housing (1), and this housing is supported in a holder (4) that is a rigid part of the body both pivotably around a transverse axis (7) and displaceably in the longitudinal direction of the steering column in relation to the body. The actually supported position is continuously lockable by two hydraulically acting piston-and-cylinder units (13, 14), which are rigidly articulated to the body, on the one hand, and are connected to the housing (1) in an articulated manner, on the other hand.

Abstract: The present invention pertains to a steering column for a motor vehicle equipped with an inflatable air bag in the steering wheel (6), in which the parts (3, 4) of a steering shaft, which are connected to one another by a universal joint (5), are rotatably mounted in a housing consisting of a movable upper housing part (1) and a lower housing part (2) rigidly attached to the body, and the two parts of the housing are connected by a hinge (7) to a hinge axis (9) that extends approximately horizontally in the plane of the intersection of the axes of the universal joint, and can be interlocked with one another by the frictional engagement of a clamping device (13).
