Abstract:
A method for the production of a connecting structure for a motor vehicle involves inserting two profile elements, connected to one another by a plastic joint element, into a tool and hardening in the tool. A fiber semi-finished product with respective receivers for corresponding connecting regions of the profile elements is produced. The connecting regions of the profile elements are connected to the respective receivers of the fiber semi-finished product. The plastic joint element is produced by injecting plastic in a transfer molding process into a forming region of the tool provided for this purpose.
Abstract:
A diagonal strut device (1) for reinforcing arrangement on an undercarriage of a motor vehicle. A plurality of struts (2) made from a fibre-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 door pillar for a supporting frame structure of a vehicle body has an upper section which extends from a vehicle roof as far as a vehicle side edge, and a lower section which extends from the vehicle side edge in the direction of a vehicle floor. In order to improve the door pillar with regard to loading and weight, it has a pillar body which extends at least in the upper section and is made of iron or iron alloy, and a pillar base which is connected fixedly thereto, extends at least in the lower section, and is made of light metal or light metal alloy.

Abstract:
A container that can be locked and fastened to a vehicle with lockable fastening devices in a detachable manner, made of material impenetrable toward gaining unauthorized access to the contents, is designed in such a way that it can be carried as a bag in the detached state and stored on the vehicle side in the empty state in a space-saving and aesthetically appealing manner. For this purpose, the container is made of a collapsible material and designed like a bag.
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 self-supporting structure for a motor vehicle with at least one transverse connection is provided. At least one transverse connection for stiffening the body structure is provided which is made in one piece from a dimensionally stable light weight metal or plastic foam and extends over the entire width of the body structure.

Each strut (2) can be connected to the undercarriage via it's 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). 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 firmly bonded cast joint. Further, a method for the production of a diagonal strut device (1), as well as a motor vehicle undercarriage, which uses the diagonal strut device (1) for reinforcement.
Abstract:
The present invention relates to a method for joining at least one joint part (3), provided with a through-opening (4), to a hollow profile (1), the joint part (3) being pushed with its through-opening (4) onto the hollow profile (1) up to a joint point (2), and the hollow profile (1) being expanded at least at the joint point (2). In order to improve the durability of the connection between joint part (3) and hollow profile (1), an adhesive (11) is arranged between an inner side (6) of the joint part (3) and an outer side (5) of the hollow profile (1) before the expansion in such a way that the adhesive (11) adheres to the inner side (6) and to the outer side (5) in the region of the joint point (2) after the expansion.
Abstract:
A connection (4) between two parts (2, 3), in particular in a motor vehicle. The two parts (2, 3) are connected to one another in a connection zone (5) via a plastic connection (6) consisting of an injection-molded plastic (8). Additionally, the two parts (2, 3) are connected to one another in the connection zone (5) via an adhesive connection (7) consisting of a cured adhesive (9).
