Abstract

The base body of the bumper comprises a cap-shaped profiled beam with its open face directed towards the vehicle. When it is required to attached the spherical head tow bar to the vehicle, a flat closure plate is placed over the open bumper face. The plate carries the mountings for the tow bar and is attached to the bumper by bolts to facilitate its removal. The leading edge of the bumper is covered with energy-absorbing material e.g. rubber. The upper side of the bumper has a cover strip.

Description

"Befestigung einer Kugelkopf-Anbängevorrichtung" "Attachment of a ball head attachment device"

Di Erfindung betrifft eine Befestigung einer Kugelkopf-Anhängevorrichtung an einem Stoßfänger eines Kraftwagens.The invention relates to an attachment of a ball head hitch on a bumper of a motor vehicle.

Die Anbringung von Anhängevorrichtungen an Stoßfängern von Kraftwagen ist z.n. aus der DT-OS 23 39 637 und der DT-OS 26 19 912 bekannt. Nachteilig bei diesen bekannten Anordnungen ist, dan an den dort verwendeten Stonfängern spezielle Vorkehrungen zur Unterbringung der Anhängevorrichtungen erforder ich sind, die eine nachträgliche Montage einer Anhängevorrichtung praktisch ausschließen, es sei denn, an allen Stoßfängern sind diese Vorkehrungen bereits ab Wcrk getroffen, obwohl nur ein sehr ger@nger Prozentsatz von Fahrzeugen überhaupt mit einer Anhängevorrichtung ausgerüstet wird.The attachment of towing devices to the bumpers of motor vehicles is z.n. from DT-OS 23 39 637 and DT-OS 26 19 912 known. Disadvantageous with these known arrangements is special because of the stone catchers used there Provisions for accommodating the towbars are required, the one The retrofitting of a trailer coupling is practically impossible, unless on all bumpers these precautions are already taken from the factory, although only a very small percentage of vehicles with a trailer hitch at all is equipped.

Diese Möglichkeit scheidet also aus finanziellen Gründen aus.This option is therefore ruled out for financial reasons.

Der vorliegenden Erfindung lag daher die Aufgabe zugrunde, eine Möglichkeit für eine einfache nachträgliche Montage einer Anhängevorrichtung an einem Stonfänger zu schaffen ohne daß dafür am serienmäßigen Stoßfänger schon irgendwelche Vorkehrungen - auch hinsichtlich der Dimensionierung -getroffen sein müssen.The present invention was therefore based on the object of providing a possibility for easy subsequent installation of a trailer hitch on a stone catcher to create without any on the standard bumper Precautions - also with regard to the dimensioning - must be met.

Dies wird erfindungsgemäß dadurclx erreicht, daß der Grundkörper des Stoßfängers von einem zum Fahrzeug hin offeneii Profilträger gebildet wird, und daß bei Elolltage der Anhängevorrichtung der Profilträger durch ein die Anhängevorrichtung tragendes Schließteil zu einem geschlossenen Hohlträger ergänzt wird.This is achieved according to the invention that the base body of the The bumper is formed by a profile beam open to the vehicle, and that at Elolltage the hitch of the profile beam through a hitch load-bearing closing part is supplemented to form a closed hollow beam.

Nach einer bevorzugten Ausführungsform der Erfindung weist dabei der Profilträger hutförmigen Querschnitt auf, so dan eine einfache Befestigung des Schließteils an den Flansche des Profilträgers möglich ist.According to a preferred embodiment of the invention, the Profile support hat-shaped cross-section, so dan a simple attachment of the locking part on the flanges of the profile beam is possible.

Da bei einer solchen Anordnung die Abstiltzung des Stoßfängers am Fahrzeug über stoßabsorbierende Elemente, wie Stoßdämpfer oder dgl. , nicht möglich ist, ist nach einer weiteren vorteilhaften Ausgestaltung der Erfindutlg vorgesehen, dan auf der dem Fahrzeug abgewandten Seite des Stoßfängers stoßabsorbierende Hittel angeordnet sind.Since with such an arrangement the Abstiltzung of the bumper on Vehicle via shock-absorbing elements such as shock absorbers or the like. Not possible is, is provided according to a further advantageous embodiment of the invention, then, on the side of the bumper facing away from the vehicle, shock-absorbing material are arranged.

Der Gegenstand der vorliegenden Erfindung soll im folgenden anhand der Zeichnung, die eine erfindungsgemäße Befestigung im Schnitt zeigt, näher erläutert werden.The subject matter of the present invention will be based on the following the drawing, which shows a fastening according to the invention in section, explained in more detail will.

Der Crundkörper des in der Zeichnung dargestellten Stoßfängers 1 wird von einem Profilträger 2 gebildet, der hutförmigen Querschnitt aufweist. Bei Montage einer Anhängevorrichtung 3 wird der Profilträger 2 durch ein @chließteil 4, das die flefestigungsteile 5 für die Anhängevorrichtung 3 trägt, zu einem geschlossenen Hohlträger ergänzt, der danii in der Lage ist, die auftretenden Kräfte aufzunehmen. Gegebenenfalls wäre lediglich eine Verstärkung der der Einleitung der Kräfte in den Unterbau des Fahrzeugs dienenden, nicht dargestellten Elemente erforderlich. Auf der dem Fahrzeug abgewandten Seite des Stoßfängers 1 sind energieabsorbierende mittel 6 (Gummi oder dgl.) angeordnet, die durch eine z.B. aus Kunststoff bestehende Verkleidung 7 abgedeckt sind. Die Oberseite des Stoßfängers 1 ist durch eine Blende 8 abgedeckt.The basic body of the bumper 1 shown in the drawing is formed by a profile support 2 which has a hat-shaped cross section. On Mondays a hitch 3, the profile support 2 by a @ closing part 4, the the flefestigungsteile 5 for the hitch 3 carries, to a closed Hollow beam added, the danii able is that occurring Absorb forces. If necessary, the introduction would only be strengthened the forces in the substructure of the vehicle serving, elements not shown necessary. On the side of the bumper 1 facing away from the vehicle, there are energy-absorbing elements means 6 (rubber or the like.) Arranged, for example made of plastic Cladding 7 are covered. The top of the bumper 1 is through a panel 8 covered.

Die erfindungsgemäß angebrachte Anhängevorrichtung 3 kann jederzeit leicht wieder entfernt werden, indem die bei 9 angedeuteten Schraubverbindungen gelöst werden. Es wäre jedoch auch denkbar,die Anhängevorrichtung 3 lösbar mit den Befestigungsteilen 5 zu verbinden.The towing device 3 attached according to the invention can be used at any time can easily be removed again by the screw connections indicated at 9 be solved. However, it would also be conceivable to releasably connect the hitch 3 to the Fasteners 5 to connect.

Insgesamt wird so eine Befestigungsmbglichkeit für eine Anhängevorrichtung geschaffen, die aucli stilistisch befriedigt da keine Teile in Form zusätzlicher Träger oder dgl. nach außen störend in Erscheinung treten.Overall, this provides a means of attachment for a trailer hitch created, which also satisfies stylistically as there are no additional parts Carrier or the like. Outwardly disturbing appearance.
