Abstract: A lock washer having a central through-opening for the passage of a clamping shaft, for example the shaft of a clamping bolt, and having a locking structure on its flat sides. At least some of the positive structures of the locking structure on one flat side of the lock washer are arranged offset in the circumferential direction in relation to positive structures on the other flat side wherein each positive structure on the opposite flat side of the washer has a negative structure extending over the radial extension of the washer, the width of which in the circumferential direction of the washer corresponds to a multiple of the width of a positive structure.

Abstract: A pair of wedge lock washers with a first wedge lock washer and with a second wedge lock washer. The two washers each have a fastener opening arranged in alignment with one another, a wedge surface structure which engages with one another on their mutually facing surfaces, and clamping structures on their surfaces facing away from one another. One of the two washers has a larger outer diameter than the other washer, and has a rotary drive contour on the radial outside for torque support of a clamping tool. The clamping structures of the washer with the larger diameter are arranged at an axial distance from the disk surface in the inner disk area thereof and are designed for the form-fitting embossing of the same into the surface of a component adjacent thereto. The apexes of the wedge surface structuring are located as positive structures on the mutually facing surfaces of the wedge lock washers in a respective plane.

Abstract: A screw fastener arrangement comprising a screw fastener, with a head and a shank, and at least one washer on the shank. A coupling sleeve is in the washer opening through which the shank passes, the coupling sleeve having a U-shaped profile which opens radially outward and is formed by two flanges spaced from each other and protruding radially outward, the coupling sleeve being held interlockingly with the at least one washer by the flange in the direction of the longitudinal axis of the washer opening. The coupling sleeve has clamping catches projecting radially inward and elastically adjustable in the direction of their longitudinal axis against the interior wall of the coupling sleeve, which, using their free end, engage in an undercut of the screw fastener, acting in a longitudinally axial direction to the coupling sleeve. Also disclosed is a washer assembly for such an arrangement.

Abstract: A screw fastener arrangement comprising a screw fastener, with a head having a ring-shaped washer contact surface and a shank, and at least one washer on the shank of the screw fastener. In this screw fastener arrangement, a coupling sleeve is in the opening of the at least one washer through which the shaft of the shank passes, the coupling sleeve having a U-shaped profile which opens radially outward and is formed by two flanges spaced from each other and protruding radially outward, the coupling sleeve being held interlockingly with the at least one washer by the flange in the direction of the longitudinal axis of the washer opening. The coupling sleeve has a plurality of clamping catches projecting radially inward and elastically adjustable in the direction of their longitudinal axis against the interior wall of the coupling sleeve, which, using their free end, engage in an undercut of the screw fastener, acting in a longitudinally axial direction to the coupling sleeve.

Abstract: A rail fastener (7) comprises an anchoring shaft (9) for fixing the rail fastener (7) in a fastening base, for instance a sleeper (2) which bears the rail (1), and a head (10) which is integrally formed on the anchoring shaft (9) and equipped with means for receiving a torque for the purpose of screwing the anchoring shaft (9) into the fastening base.

Abstract: The present invention relates to a frame side component of bodywork of a motor vehicle, preferably a car, where, respectively, a metal outer frame manufactured as a single piece and a metal inner frame manufactured as a single piece, where these respectively have at least one aperture delimited by a roof arch segment, a body-floor longitudinal-member segment and a central-column segment, are securely connected to one another, and the cavities produced between metal outer frame and metal inner frame via the connection are reinforced by reinforcement structures composed of moulded-on plastic and the reinforcement structures enter into a secure metal-plastic connection with the two frames.

Abstract: The present invention relates to a transverse-member module for receiving the instrument panel and reinforcing the bodywork via direct connection of the two A-pillars of a motor vehicle, composed of a transverse member with a steering-column retainer, where the transverse-member module, i.e. not only the transverse member but also the steering-column retainer, are produced using a metalplastic-composite design (hybrid technology).

Abstract: A device for the reduction of injuries in the event of a motor-vehicle accident comprises an adapter inserted between the vehicle bodywork and adjacent internal vehicle components to reduce the free space distance between the bodywork and the components. The free space distance is the shortest direct distance between a vehicle component and the adjacent bodywork which is free from other parts. The adapter changes the energy transfer involved in a collision between a person and the vehicle, in order to reduce the risk of injury to the head.
