Abstract

The accident protection device (1) is attached below the trailer sided towing bar. The fastening holes of the protection device are executed for common ramp braking device. A plate is welded with transverse struts (2) to a holder. The protection device is firmly screwed with the trailer towing bar. The struts are provided between a protective plate and a fastening part. The components of the accident protection device are formed of stable steel.

Description

Die Erfindung betrifft eine Schutzvorrichtung für Pkw-Anhänger, insbesondere für Anhänger hinter Personenkraftwagen.The invention relates to a protective device for car trailers, especially for trailers behind passenger cars.

Hintergrund der ErfindungBackground of the invention

Bei Unfällen mit Pkw-Anhänger Zügen (sog. Gespannen) kann es zu einer Gefährdung der Insassen durch die Anhängerdeichsel kommen. Während des Unfalls kann es aufgrund der starken Verzögerung dazu kommen, dass die Anhängerdeichsel in das Fahrzeuginnere dringt und damit die Insassen auf der Rückbank gefährden kann.In the event of accidents involving passenger car trains (so-called trailers), the occupants may be endangered by the trailer drawbar. During the accident, it can happen because of the strong delay that the trailer drawbar penetrates into the vehicle interior and thus endanger the occupants in the back seat.

Der Stand der Technik zur Verhinderung des Eindringens der Deichsel in das Fahrzeugheck wird unter anderem durch das Dokument DE 8219363U1 bzw. DE 19927017 dargestellt. Es handelt sich hier um Sicherheitsdeichseln, die sich in ähnlicher Form durch bestimmte Knickstellen für V-Deichseln oder Rohrdeichseln auszeichnen. Diese Knickstellen sollen das Abknicken der Zugdeichsel gewährleisten und ein Eindringen in den Pkw-Innenraum verhindern. Diese Lösungen schwächen jedoch die Struktur der Anhängerdeichsel.The prior art for preventing the drawbar from entering the rear of the vehicle is described inter alia by the document DE 8219363U1 respectively. DE 19927017 shown. These are safety tongs, which are characterized in similar form by certain kinks for V-drawbars or pipe drawbars. These kinks are intended to ensure the buckling of the drawbar and prevent intrusion into the passenger compartment. However, these solutions weaken the structure of the trailer drawbar.

Der Anmelder selbst hat in DE 10 2006 010 462 B4 einen Aufprallschutz beansprucht, der das Eindringen der Zugdeichsel fahrzeugseitig verhindern soll. Hierbei handelt sich allerdings um eine Schutzplatte, die jeweils an eine Anhängerkupplung angepasst werden muss und für jede Fahrt neu montiert werden muss.The applicant himself has in DE 10 2006 010 462 B4 claimed an impact protection, which should prevent the penetration of the drawbar vehicle side. However, this is a protective plate, which must be adapted to a trailer hitch and must be re-assembled for each ride.

Die vorliegende Erfindung gleicht die Nachteile der bisherigen Erfindungen in nachfolgender Weise aus:
Die Erfindung beinhaltet eine Schutzplatte, die anhängerseitig unterhalb der Auflaufbremsvorrichtung angebracht ist. Sie braucht nicht demontiert zu werden. Mit Hilfe dieser Schutzplatte soll bei einer starken Abbremsung des Pkw das Eindringen der Anhängerdeichsel in den Innenraum des Pkw verhindert werden. Dabei nutzt die Erfindung aus, dass sich in Crashversuchen, welche vom Anmelder an der Hochschule für Technik und Wirtschaft Berlin durchgeführt wurden, gezeigt hat, dass sich die Anhängerdeichsel auf dem Querträger der Kupplungskugelhalterung abstützen kann. Dadurch kann das Eindringen der Anhängerdeichsel in den Pkw-Innenraum verhindert bzw. erschwert werden. Erfindungsgemäß soll die Schutzplatte dafür sorgen, das Abstützen der Deichsel auf dem besagten Querträger sicherzustellen.The present invention compensates for the disadvantages of the previous inventions in the following way:
The invention includes a protective plate which is mounted on the trailer side below the overrun brake device. It does not need to be dismantled. With the help of this protective plate to prevent the penetration of the trailer drawbar in the interior of the car in a strong deceleration of the car. The invention exploits that in crash tests, which were carried out by the applicant at the University of Applied Sciences Berlin, has shown that the trailer drawbar can be supported on the cross member of the coupling ball mount. As a result, the penetration of the trailer drawbar in the passenger compartment can be prevented or made more difficult. According to the invention, the protective plate should ensure that the supporting of the drawbar on the said cross member is ensured.

Zusammenfassung der ErfindungSummary of the invention

Aufgabe der Erfindung ist es, eine verbesserte Vorrichtung für eine Anhängerdeichsel anzugeben, mit der ein verbesserter Schutz bei einem Aufprall des anhängerseitigen Kupplungsbauteils geschaffen ist. Die Erfindung wird durch eine Unfallschutzvorrichtung für eine Anhängerdeichsel mit den Merkmalen des Anspruchs 1 gelöst.The object of the invention is to provide an improved device for a trailer drawbar, with which an improved protection is provided in an impact of the trailer-side coupling component. The invention is achieved by an accident protection device for a trailer drawbar with the features of claim 1.

Die Erfindung umfasst den Gedanken, dass die Unfallschutzvorrichtung nicht am Pkw sondern am Anhänger angebracht ist und dadurch die Struktur der Anhängerdeichsel nicht geschwächt wird. Dadurch, dass die Anbringung unterhalb der Auflaufbremsvorrichtung erfolgt, stützt sich im Crashfall die Unfallschutzvorrichtung am Querträger der zugfahrzeugseitigen Anhängerkupplung ab. Die Erfindung hat gegenüber dem Stand der Technik den Vorteil, dass sie einfach an der Anhängerdeichsel befestigt werden kann und die Bewegungsfreiheit unter normalen Betriebsbedingungen nicht einschränkt.The invention includes the idea that the accident protection device is not attached to the car but on the trailer and thus the structure of the trailer drawbar is not weakened. The fact that the attachment is carried out below the overrun brake device, in the event of a crash relies on the accident protection device on the cross member of the towing vehicle side hitch. The invention has the advantage over the prior art that it can be easily attached to the trailer drawbar and does not restrict the freedom of movement under normal operating conditions.
