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 (α) and austenite (γ) crystals. In the case of a triplex steel, it comprises, additioally to said two phases, martensitic (ε) and/or (κ) 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:
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 flexible planar structure unit is provided as load-space securing element, the unit being arranged extended in a protective position in the vicinity of the moveable rear-section arrangement in such a way that loads which are located in the load space, or at least a person who is located on a seat arrangement facing counter to the direction of travel in the load space is protected with points of attachment to the vehicle bodywork being provided for securing the planar structure unit in the extended protective position.
Abstract:
A scuttle structure for a drive unit of a motor vehicle is disclosed which includes a scuttle for the drive unit which is displaced to the rear in the event of a head-on collision. A slide-down aid is fastened to the scuttle in such a way that, after shearing stress caused by a head-on collision, at least part of the slide-down aid slides down on the scuttle. By means of this scuttle structure, an intrusion of parts of the drive unit into the scuttle is prevented and the sliding-down action of the drive unit on the scuttle structure is assisted.
Abstract:
A bumper assembly for a motor vehicle is disclosed which can be fastened via at least one supporting element and, by means of a screw connection, on a part fixed to the vehicle. A foam energy absorber is provided on which the at least one supporting element is mounted. The supporting element, which reaches virtually over the entire height of the energy absorber, is designed approximately in the form of an umbrella. The umbrella edge, which terminates flatly, bears on the part fixed to the vehicle and, at a distance from the umbrella edge on the underside of the supporting element, supporting webs are provided which are likewise supported on the part fixed to the vehicle.
Abstract:
A diagonal strut device (1) for reinforcing arrangement on an undercarriage of a motor vehicle. A plurality of struts (2) made from a fiber-reinforced plastic composite material extend away from a central joint element (3). Each strut (2) can be connected to the undercarriage via this from the end facing away from the central joint element (3). For this, a connecting joint element (4) is arranged on the end of each strut (2) facing away from the central joint element (3), wherein the central joint element (3) and the connecting joint elements (4) are formed from a light metal material. The central joint element (3) and the connecting joint elements (4) are then connected to the struts (2) by an at least positive connection. The central joint element (3) and the connecting joint elements (4) are each formed from several individual elements joined together.

Abstract:
A method for producing a body-in-white of a passenger car is provided. A support structure assigned to the body-in-white of the motor vehicle and which includes at least one support part is produced. The support part of the support structure is, depending on a variant of the motor vehicle, at least in some regions provided with at least one reinforcing part.
Abstract:
The invention relates to a lightweight component for a vehicle body, which forms at least one closed frame. The lateral parts of the frame are designed as cast components and joined by at least one reinforcement profile disposed between the lateral parts, the end regions of the reinforcement profile being cast around by the cast components with a positive and adhesive connection. The invention further relates to a method for the production of such lightweight components.
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.
