Abstract: The invention pertains to a theftproofing system for motor vehicles with a locking member which can be engaged in a recess of a closing ring arranged concentrically to a steering shaft (9) and firmly connected to it and, when the locking member is engaged, blocks the steering shaft until a limiting torque is introduced into it.According to the invention, it is proposed that, in the frictional connection between the steering wheel (steering wheel spoke 5) and steering shaft, a slip clutch (3, 4, 8) be provided whose transmittable torque is lower than the limiting torque.

Abstract: A motor vehicle engine mount has two inner bodies which are directed toward each other and form a gap therebetween. Each of these bodies is connected to the interior of a frame via rubber webs and a connecting piece rigidly attached to one of the inner bodies is held in a sliding manner on the other inner body via a slot and a locking screw in the position which becomes established in the loaded resting state. And a release member is added between the screw and such other inner body that is able to freely move at small vibration amplitudes.

Abstract: A horn operating means has two contact plates separated from each other by a resilient foam sheet. For contacting, one of the contact plates is deformed by the operating force so much that it will touch the other contact plate. In one embodiment, grooves in the central region of one of the contact plates provide for the necessary operating forces not being greater in the central region than in the edge region.

Abstract: A hydraulic mounting has a nozzle plate with a membrane separating a working chamber from an equalizing chamber and a ring channel connecting these chambers. A filler channel leads radially from the outside into this ring channel and makes it possible to fill the hydraulic mounting, without air bubbles, with hydraulic fluid. A closure member closes off the filler channel on the outside.

Abstract: A mounting device is disclosed for mounting a drive unit in a motor vehicle having a pin that is rotationally symmetrical and seats in an elastomeric portion of a damping block so as to be capable of rotation about an axis longitudinal of the drive unit.
