Der Erfindung liegt die Aufgabe zugrunde, ein Frontteil der oben genannten Art zu schaffen, bei dem im Kollisionsfalle der Überzug nicht auf die volle Länge der freien Kanten der am Träger angeordneten Rippen auftrifft, um zunächst eine partielle Deformierung der Rippen einzuleiten, wodurch mit zunehmender Verformung des Überzuges und der Rippen der Rippenwiderstand langsamer ansteigt.Of the Invention is based on the object, a front part of the above To create a type, in which in case of collision, the coating is not on the full length of the free edges of the carrier arranged ribs incident to first a partial deformation initiate the ribs, thereby increasing the deformation of the coating and the ribs the rib resistance increases more slowly.
Diese Aufgabe wird bei einem Frontbauteil der eingangs genannten Art nach der Erfindung durch die kennzeichnenden Merkmale des Patentanspruchs 1 gelöst.These Task is in a front component of the type mentioned after the invention by the characterizing features of the claim 1 solved.
Für die Erfindung ist wesentlich, daß die Vorschriften des Fußgängerschutzes, die für Kraftfahrzeuge, insbesondere PKWs, vorgesehen sind, besser erfüllt werden können. Diese Vorschriften sehen an definierten Kontaktflächen die Einhaltung vorgegebener Wirkgrößen bestimmter biomechanischer Werte vor, um Fußgängern einen verbesserten Schutz bei einer Kollision mit einem Fahrzeug zu bieten. Dies wird in einem derartigen Kollisionsfall durch die sich nach und nach stärker verformenden Rippen erfüllt, die sich erfindungsgemäß über einen längeren Weg verformen, weil die Krafteinleitung über den Überzug zunächst punktförmig erfolgt. An den Auftreffstellen der Rippen setzt eine Biegung oder Drehen der Rippen ein, die sich erst nach und nach bis in den von dem Überzug weiter abliegenden Bereich der Rippen fortsetzt. Durch die Rippengeometrie, den Wandstärkenverlauf der Rippen und die Winkellage der Rippen relativ zum Träger sowie zum Überzug kann das gewünschte Dämpfungsverhalten der Rippen erzielt werden. Insbesondere lassen sich gemäß dem erfindungsgemäßen Frontbau teil Stoßfänger und benachbarte Frontbereiche eines PKWs oder Kleinlastkraftwagens ausführen.For the invention is essential that the Regulations of pedestrian protection, the for Motor vehicles, especially cars, are provided to be better met can. These regulations see at defined contact surfaces the Adherence to specified effective quantities of certain biomechanical values to provide pedestrians with improved protection in a collision with a vehicle. This will be done in one such collision case by the more and more deforming gradually Filled ribs, according to the invention via a longer way deform, because the introduction of force on the coating is initially punctiform. At the impact sites The ribs make a bend or turn of the ribs that are only gradually to the area of the area further away from the coating Ribs continue. Through the rib geometry, the wall thickness gradient the ribs and the angular position of the ribs relative to the carrier as well to the coating can the desired damping behavior the ribs are achieved. In particular, it is possible to participate according to the front construction according to the invention Bumpers and Carry out adjacent front areas of a car or small motor vehicle.
