Abstract: An A-pillar for a motor vehicle running from a vehicle roof in the direction of a vehicle floor and having a curved profile over at least one longitudinal section, has an essentially solid circumferential surface and is of essentially hollow configuration in an inner region. The A-pillar in its curved longitudinal section has a reinforcement strut which passes through a hollow cross section of the A-pillar. The reinforcement strut runs from a rear wall region of the A-pillar to a front wall region. The reinforcement strut may have an elliptical or a circular recess along an upper and a lower boundary line. The A-pillar thus achieves high strength at reduced weight.

Abstract: The invention concerns a steel for lightweight construction, consisting of a multiphase structure. In the case of a duplex steel, it consists of mixed ferrite (?) and austenite (?) crystals. In the case of a triplex steel, it comprises, additioally to said two phases, martensitic (?) and/or (?) phases. The volumetric weight of the inventive steel is low as a result of the high proportion of light alloys A1, Si Mn, Mg, Ga and Be. The inventive alloys have a volumetric weight of less than 7b/cm3.

Abstract: Interconnectable profiled elements (1, 2), in particular for panel-type structural components of motor vehicles, having, on opposite joining edges, a respective projecting connecting web (3) and a respective recess (4), which peters out in open form into the relevant joining edge at a distance from this connecting web (3), for receiving the connecting web (3) of an attached profiled element (1, 2) having a joining edge of complementary design are intended to be joinable at different distances from one another. By this means, it is intended to be able to obtain an exact length measurement for a component joined together from a plurality of profiled elements. For this purpose, the webs (3) and recesses (4) are provided in a shape which permits the profiled elements (1, 2) which are to be connected to one another to be joined at different distances from one another within a predefinable range of tolerances.

Abstract: The invention relates to a motor vehicle (1), the passenger cell (2) of which is integrated into the rest of the vehicle as a separate unit. The motor vehicle (1) has a device, by means of which, in the event of a crash, the passenger cell (2) can be moved in the longitudinal direction of the vehicle relative to the rest of the vehicle and at the same time upward, via guide surfaces (15), which are arranged on the rest of the vehicle and against which the passenger cell (2) bears. In order to reduce the risk of injury for the vehicle occupants in the event of a crash, it is proposed that the device be designed in such a manner that the passenger cell (2) can be moved in the opposite direction to the impact.

Abstract: In a peripheral connecting region of two sheets including two overlapping flanges of the sheets, the sheets are connected to each other such that they cannot be displaced relative to each other. In order to be able to connect high-strength sheets or other sheets which can be difficult to weld to each other, the sheets are connected in the connecting region by a strip-shaped fastening element. The strip-shaped fastening element encloses the outer contour of the flanges and rests with some sections of its inner side on mutually remote surfaces of the two flanges. A method for producing the connecting region is also proposed.

Abstract: A motor vehicle body, having a roof module which is placed onto a support structure and is adjoined by a lid (engine hood) for closing a space (engine compartment on an end region of the body, the lid being held on the body via a bearing arrangement in the vicinity of the roof module. In order to position the lid in relation to the adjacent roof module with relatively little technical outlay, the bearing arrangement is arranged directly on the roof module and can therefore already be prefitted to the roof module before the roof module is placed onto the support structure.

Abstract: The invention relates to a body for a motor vehicle, which comprises a support structure (10) having a roof module (42) which is placed onto a basic module (12), a roof column (50) extending between the roof (43) of the roof module (42) and the basic module (12), which roof column is to be fixed at its lower end (64) on the basic module (12) during assembly of the partial modules (12, 26, 42, 50, 52). In order to achieve a different modularization of the support structure (10) with an improved crash stability of the body, the roof column (50) is designed as a separate component which is to be fastened at its upper end (60) in an overlapping manner to a support part (62) protruding from the roof (43).

Abstract: The invention relates to a motor vehicle body, the support structure (10) of which is composed of large-size partial modules (12, 34, 50, 66), a basic module (12) comprising lateral longitudinal members (15) and a body floor (14) and reaching laterally as far as front wall columns (20), and, when the support structure (10) is assembled, the basic module (12) being connected to a front end module (34) which belongs to the front crumple zone of the motor vehicle and is supported in a crash stable manner on the basic module (12). In order to provide a motor vehicle body, in which the front end module (34) even without a roof construction is fixed in a sufficiently stable manner on the basic module (12), a front end region (36) of the body floor (14) belongs to the front end module (34) and extends rearward over a considerable length region of the basic module (12) between lateral longitudinal member sections (16).

Abstract: The support structure of a body for a motor, vehicle is assembled from large-size partial modules. Two partial modules connected to each other comprise support sections and wall and/or floor sections connected thereto. Support sections of one partial module are connected to associated support sections of the other partial module at abutment points. In order to design a highly stressed connection between partial modules of the support structure in a very stable and simple manner, the support sections of the two partial modules, which support sections are assigned in each case to one another, are assembled to form a continuous support. Abutting surfaces of the assembled support sections run obliquely with respect to the direction of extent of the support. This oblique profile of the abutting surfaces creates a connection over a very large area in relation to the cross section of the support, which ensures an extremely stable connection of the two parts to each other.

Abstract: A detachable closure includes separable burr-type elements which, at surfaces to be joined, have interlocking elements which mutually interlock during joining of the burr-type elements and hold the burr-type elements together. The interlocking elements are made of a material which carries out a deformation under the influence of heat, electromagnetic radiation, and/or a magnetic field.

Abstract: A die casting machine has a divisible die casting tool. To be able to die cast in a secure manner large die-cast parts beyond elasticity-caused limits of the machine construction, the locking pressures for the die casting tool are transmitted by tool-integrated tie rods into a power flux circuit remaining within the die casting tool. In the closed condition of the die casting tool, the tie rods can be anchored in a tension proof manner on both sides of its mold parting surface in the die casting tool and, for the opening, can be detached at least from one of the tool parts of the die casting tool. For limiting the flow paths of the molten mass, several casting cylinders for feeding the casting material into the casting mold are distributed thereon so that the casting mold can be filled simultaneously from several points.

Abstract: A flat cast structural member, particularly a cast metal part or a cast plastic part wherein the surface of the structural member is covered by a thin metal sheet or a plastic layer. An adhesive or coupling layer is provided between the thin metal sheet or plastic layer, whereby under the influence of heat, the adhesive or coupling layer absorbs any surface unevenness or irregularities on the structural member.

Abstract: A welded joint is made between a sheet-steel component and a sheet-aluminum component by way of a lap or web weld. Hat-like clip parts are pushed through openings in the sheet-aluminum component. The clip parts are welded at their bottom to the sheet-steel component and overlap the exposed flat side of the sheet-aluminum component with their flanges, which form the free rims. In order to improve the quality of the weld, an adhesive is introduced into a gap situated between the clip part and the sheet-aluminum component.

Abstract: Methods for casting thin-walled structural elements made of alloy for automobile bodies using the diecasting, thixocasting, or thixoforming methods, as well as corresponding structural elements are described. In order to produce by these methods in particular body side wall parts including the A, B and C pillars, the castings are cast in several casting slices. The casting slices of a casting are cast, staggered timewise in succession using the same method and from the same alloy but in different casting molds or different parts of a casting mold. At the seams, the casting slices are cast together along a defined shapewise contour. The casting slices can be case together indirectly with interposition of a separate seam strip. However, they can also be cast onto one another, with an already cast first casting slice being placed in a second casting mold and cast together therein with the second casting slice.
