Abstract: A press-hardened component and a method for producing press-hardened components, in particular a bodywork component, from a semi-finished product made from unhardened, hot-formable steel sheet. Various process steps are carried out in the process. A component blank is formed from the semi-finished product by a cold-forming process, in particular a drawing process. The component blank is trimmed at the margin side to a margin contour which approximately corresponds to the component to be produced. The trimmed component blank is heated and press-hardened in a hot-forming tool, and then the press-hardened component blank is covered with a corrosion-prevention layer in a coating step.

Abstract: The invention relates to the assembly of a roof module and a vehicle body. The roof module lies on flanges of the roof section of the vehicle body and is bonded to said flanges by means of an adhesive layer. To obtain a desired, predetermined thickness for the adhesive layer between the roof module and flanges by a reliable process and to prevent adhesive from escaping from the bonding area, spacers are provided in the area of the flange. Said spacers allow the distance between the interior surface of the module, said surface facing the flange, and the upper surface of the flange, said surface facing the roof module, to be set to a predetermined measurement.

Abstract: A roof frame arrangement of a motor vehicle has a front, a rear and two lateral roof frames, and a supporting device for a motor vehicle tailgate. The supporting device includes a tailgate hinge and at least one gas-filled compression spring. At least the lateral roof frame contains an inner shell and an outer shell connected to the latter. A hollow space is formed between the inner shell and outer shell. In order to provide a roof frame arrangement having increased stiffness, which can be produced in a simple and space-saving manner and with as few manufacturing tolerances as possible and in which a relatively great outlay on leakproofness is not required, it is proposed to form a rear end region of the lateral roof frame as a single-piece, circumferentially closed hollow profile which encloses the hollow space there and forms a receiving housing in which at least one of the hinge and the gas-filled compression spring is fitted.

Abstract: A rear roof frame of a motor vehicle has a tailgate which is fastened to the roof frame and includes an upper shell and a lower shell which is fitted to the latter. For the design of a rear roof frame, which, in spite of the shell-type construction, provides, in a simple manner and lightweight construction, sufficient torsional and flexural stiffness in order to withstand high mechanical stresses, it is proposed to arrange within the shell structure a hollow profile which leads in each case from the transition region to the lateral roof frame and parallel to the longitudinal extent of the structure, and emerges, at least at the end facing away from the lateral roof frame, in a knee which kinks in the front-end direction of the vehicle. The end of the rear roof frame forms a tubular hollow profile of the lateral roof frame, which is connected to the hollow profile of the rear roof frame.

Abstract: A door arrangement for a motor vehicle has a pivotable door and at least one hinge via which the door is articulated on one of its narrow sides on bodywork. Movement of the door between its open and closed positions proceeds, under automatic control, about two axes of rotation running approximately parallel through the hinge. During opening of the door, in a first movement stage, the hinge-side end region of the door is guided in a pivoting/sliding manner out of the door opening and the lock-side end region of the door is guided in a pivoting/sliding manner by guide elements along the door opening into a release position. Thereafter, the axis of rotation moved together with the door is shifted out of the door opening, and the door can be pivoted exclusively about the shifted axis of rotation in a second movement stage.

Abstract: Self-supporting body shell structure for a passenger motor vehicle as well as a process for manufacturing it, has side panels with different reinforcing plates or partitions for reinforcing the side panel area. Each side panel is assembled of an interior side panel half joined together in one piece and a correspondingly profiled exterior side panel half. The reinforcements are a one-piece common integral component which is integrated between the two side panel halves.

Abstract: A motor vehicle with a lowerable roof construction, particularly a convertible sports car, has a roof part and a rear part as well as a forced control device for controlling the relative movement of the roof part with respect to the rear part. The forced control device has at least one control element which is connected in the region of the roof swivel axis in a rotationally fixed manner to the roof part and interacts with at least one further control element which is fixed to the body of the vehicle and is in the region of the rear swivel axis.
