Aus
der
Zur Befestigung der bekannten Stoßfängerverkleidung sind für jede der Stützstreben des Stoßfängerinnenteils eine horizontale Gegenfläche an der Oberseite des Biegequerträgers und zwei Befestigungslöcher an einer vertikalen Wandseite des Biegequerträgers vorzusehen. Durch eine derartige konstruktive Gestaltung kann aber unter Umständen das Deformationsverhalten des Biegequerträgers im Falle eines Aufpralls auf den Kraftwagen nachteilig beeinflusst werden.to Attachment of the known bumper cover are for each of the struts of the bumper inner part a horizontal counter surface at the top of the bender crossmember and two mounting holes to provide on a vertical wall side of the bending cross member. By a However, such structural design may under certain circumstances the deformation behavior of the bending crossmember in the event of an impact on the car adversely affected become.
Ferner
ist aus der
Dabei ist für jedes Stützelement der Verstärkungsanordnung ein zugehöriges Befestigungsloch an der Oberseite des Biegequerträgers vorzusehen, wodurch jedoch unter Umständen das Deformationsverhalten des Biegequerträgers im Falle eines Aufpralls auf den Kraftwagen nachteilig beeinflusst werden kann. Des weiteren ist die Montage des Stoßfängers aufgrund der Vielzahl der Stützelemente der Verstärkungsanordnung und der zugehörigen Befestigungsmittel verhältnismäßig zeit- und kostenintensiv.there is for each support element the reinforcement arrangement a related one Fixing hole at the top of the Biegequerträgers provide, whereby however, under certain circumstances the deformation behavior of the bending cross member in the event of an impact can be adversely affected on the car. Furthermore is due to the mounting of the bumper the variety of support elements the reinforcement arrangement and the associated Fasteners are relatively timely and costly.
Schließlich ist
aus der
An der hinteren Wandseite des Biegequerträgers ist ein dämpfender Schaumkörper angeordnet, der im Falle eines Aufpralls kleinere Stöße auf die Hinterseite des Stoßfängers absorbiert. Der leistenförmig ausgebildete Schaumkörper weist einen U-förmigen, an den Biegequerträger angepassten Querschnitt auf und ist auf einen hinteren Endabschnitt des Biegequerträgers aufgeschoben, wobei der Schaumkörper mit einem schmalen Randstreifen zwischen der Oberseite des Biegequerträgers und der Stoßfängerverkleidung abgestützt ist. Der Randstreifen des Schaumkörpers wird bei einer Durchbiegung der Stoßfängerverkleidung zwischen der Stoßfängerverkleidung und der Oberseite des Biegequerträgers zusammengedrückt und ermöglicht so in begrenztem Umfang eine vertikale Abstützung der Stoßfängerverkleidung in ihrem Mittelbereich.At the rear wall side of the bender crossmember is a more muffling foam body arranged in the event of an impact minor impact on the Rear of the bumper absorbed. The strip-shaped trained foam body has a U-shaped, to the bending crossmember adapted cross section and is on a rear end portion of the bending crossmember deferred, the foam body with a narrow edge strip between the top of the bending cross member and the bumper fascia supported is. The edge strip of the foam body is at a deflection the bumper fascia between the bumper fascia and the top of the bender crossmember and compressed allows so to a limited extent a vertical support of the bumper fascia in their middle area.
Um hierbei eine ausreichend steife Abstützung der Stoßfängerverkleidung zu gewährleisten darf allerdings der vom nachgiebigen Schaumkörper zu überbrückende Abstand zwischen der Oberseite des Biegequerträgers und der Stoßfängerverkleidung nicht zu groß bemessen sein. Somit sind in Abhängigkeit vom Querschnitt des Biegequerträgers nur bestimmte konstruktive Gestaltungen der Außenkontur der Stoßfängerverkleidung möglich.Around In this case, a sufficiently rigid support of the bumper fascia to ensure however, the gap between the flexible foam body to be bridged Top of the bending crossmember and the bumper fascia not too big be. Thus are dependent from the cross section of the bending crossmember only certain structural designs of the outer contour of the bumper fascia possible.
Aufgabe der Erfindung ist es, einen Stoßfänger für einen Kraftwagen der im Oberbegriff des Anspruchs 1 genannten Art dahingehend weiterzuentwickeln, dass die konstruktive Freizügigkeit bei der Gestaltung der Außenkontur der Stoßfängerverkleidung erheblich vergrößert ist.task The invention is to provide a bumper for a Motor vehicle referred to in the preamble of claim 1 way to that effect to develop that constructive freedom of design the outer contour the bumper fascia is considerably increased.
Diese Aufgabe wird erfindungsgemäß durch die Merkmale des Anspruchs 1 gelöst.These The object is achieved by the Characteristics of claim 1 solved.
Weitere die Erfindung in vorteilhafter Weise ausgestaltende Merkmale enthalten die Unteransprüche.Further the invention advantageously features ausgestaltende features the dependent claims.
Der mit der Erfindung erzielte Vorteil besteht darin, dass die Außenkontur der Stoßfängerverkleidung weitgehend unabhängig von der Geometrie des Biegequerträgers gestaltet werden kann, da zur Überbrückung des Abstandes zwischen Stoßfängerverkleidung und Schaumkörper wenigstens ein Stoßfängerinnenteil vorgesehen ist, über welches die Stoßfängerverkleidung auf Abstand zum Biegequerträger gehalten ist, wobei die Stoßfängerverkleidung über das Stoßfängerinnenteil am Schaumkörper abgestützt ist, so dass auf Befestigungslöcher am Biegequerträger verzichtet werden kann.Of the achieved with the invention advantage is that the outer contour the bumper fascia largely independent can be designed by the geometry of the bending cross member, there to bridge the Distance between bumper panel and foam body at least one bumper inner part is provided over which the bumper panel at a distance to the bending cross member is held, with the bumper cover over the Bumper inner part on the foam body supported is, so on mounting holes on the bending crossmember can be waived.
Zur besonders einfachen und kostengünstigen Montage des Stoßfängers kann zur Abstützung der Stoßfängerverkleidung im Mittelbereich des Stoßfängers ein einziger Schaumkörper vorgesehen sein.to particularly simple and inexpensive Mounting the bumper can to support the bumper fascia in the middle area of the bumper only foam body be provided.
Zur weiteren Erhöhung der Abstützsteifigkeit kann vom Stoßfängerinnenteil nach unten eine Stützleiste abstehen, die mit der gegenüberliegenden Oberseite des Schaumkörpers zusammenwirkt.to further increase the Abstützsteifigkeit can from the bumper inner part down a support bar stand out with the opposite top of the foam body interacts.
Zur seiner besonders einfachen und zuverlässigen Befestigung am Biegequerträger kann der Schaumkörper einen U-förmigen Querschnitt aufweisen und einen oberen Teilquerschnitt des Biegequerträgers umgreifen.to its particularly simple and reliable attachment to the bending cross member can the foam body a U-shaped Have cross-section and engage around an upper part of the cross-section of the bending cross member.
Um auch bei einem Biegequerträger mit einer schräg geneigten Oberseite eine ebene Auflagefläche zur Abstützung der Stoßfängerverkleidung zu ermöglichen, kann der Querschnitt des Schaumkörpers zum weitgehenden Ausgleich der Neigung keilförmig gestaltet sein.Around also with a bending cross member with a sloping inclined top a flat support surface for supporting the bumper fascia to enable may be the cross section of the foam body be designed wedge-shaped for the most part to compensate for the inclination.
Damit sich der Schaumkörper in besonders einfacher Weise positionsgenau am Biegequerträger vormontieren lässt, kann der Schaumkörper eine rinnenförmige Vertiefung aufweisen, in die ein überstehender Wandbereich des Biegequerträgers passgenau eingreift.In order to itself the foam body premounted in a particularly simple manner positionally accurate on the bending cross member leaves, can the foam body a trough-shaped Have depression in which an overhanging wall portion of Bending crossmember engages accurately.
Der Schaumkörper kann zu seiner besonders einfachen Sicherung in Fahrzeugquerrichtung mindestens eine abstehende Befestigungsnase aufweisen, die lagesichernd in ein zugehöriges Befestigungsloch des Stoßfängerinnenteils eingreift.Of the foam body For its particularly simple securing in the vehicle transverse direction at least have a protruding mounting lug, the position securing in a related one Mounting hole of the bumper inner part intervenes.
Der Stoßfänger ist zur Anordnung im Bereich einer Ladekante des Kraftwagens besonders geeignet, da hier beim Be- und Entladen das Risiko einer Stoßbeaufschlagung der Stoßfängerverkleidung besonders hoch ist.Of the Bumper is for arrangement in the region of a loading edge of the motor vehicle in particular suitable, since here during loading and unloading the risk of shock the bumper fascia is particularly high.
