Abstract: The present disclosure concerns an automotive vehicle bodywork part including an external panel and an internal support connected behind the external panel. The internal support includes a plurality of ornamental projections projecting from said internal support-forming an ornamental motif. The external panel includes a plurality of through-holes forming a corresponding hole motif, the internal support being assembled to said external panel such that the plurality of ornamental projections are inserted though corresponding through-holes.

Abstract: A method for welding an add-on part to a component, in particular for a motor vehicle, using the in per se known torsional ultrasonic welding method having a sonotrode for transferring the vibrations generating the welding add-on part has a coupling flange for coupling the vibrations of the sonotrode and the add-on part has coupling elements for coupling the vibrations induced by the sonotrode in the welding region facing the weld interface area of the component, and the coupling elements thereby melt during the welding process and thus weld the add-on part to the component.

Abstract: An injection-molded structural component, particularly for automotive front end carriers, with a hollow structural section, the hollow structural section including a section body having a cavity with an opening, a section lid secured to the section body via a hinge and hinge-folded onto the opening, and a fastener element for fastening the section lid to the section body such that the hollow structural section withstands dynamical load.

Abstract: An injection-moulded structural component with a hollow structural section, said hollow structural section comprising a section body (24) having a cavity (30) with an opening (34), a section lid (26) secured to said section body via a hinge (28) and hinge-folded onto said opening, and a means (46) fastening the section lid (26) to the section body (24) such that the hollow structural section withstands dynamical load. Preferred application to automotive front end carriers.

Abstract: A method for connecting a component having a visually relevant front and a visually irrelevant rear to an add-on component. In order to make it possible to interconnect flat components, such as bumpers, by mechanical dovetailing, thereby ensuring a cost-effective way of interconnecting thin-walled fiat class A painted components, recesses are produced in the rear of the component, said recesses being oriented at different angles to the surface normal of the rear of the component. The recesses do not break through the visually relevant front but end at such a distance to the front at which no visible deformations to the front are produced. The add-on component is then mortised and form-locked with the component via connecting bodies, said connecting bodies being inserted with one end into the recesses and with the other end projecting through the add-on component or being fastened thereto.
