Description
Die Erfindung betrifft ein Fahrzeug mit einem Biegeträger und einer Stoßfängereinheit, wobei zwischen Biegeträger und Stoßfängereinheit ein Absorberelement angeordnet ist.The The invention relates to a vehicle with a bending beam and a bumper unit, being between bending beams and bumper unit an absorber element is arranged.
Zur Absorption kinetischer Energie, die bei einer Kollision des Fahrzeuges über eine Stoßfängereinheit auf eine Fahrzeugkarosserie wirkt, sind Absorberelemente zwischen Stoßfängereinheit und Fahrzeugkarosserie angeordnet. Heutige Fahrzeuge verfügen über eine aktive am Fahrzeug angeordnete Fußgängerschutzvorrichtung, die eine Sensorik im Stoßfänger zu deren Auslösung aufweist, mit der ein Unfall oder eine Kollision detektierbar ist.to Absorption of kinetic energy in a collision of the vehicle over a bumper unit acts on a vehicle body, absorber elements are between bumper unit and vehicle body arranged. Today's vehicles have one active pedestrian protection device disposed on the vehicle, the a sensor in the bumper too their triggering has, with which an accident or a collision is detectable.
Es ist ein Fahrzeug bekannt, welches einen Biegeträger und eine Stoßfängereinheit aufweist, wobei zwischen dem Biegeträger und der Stoßfängereinheit ein aus einem Schaum gebildetes Absorberelement angeordnet ist. In das Absorberelement ist an einer dem Biegeträger zugewandten Seite eine Nut eingebracht, in welcher eine Schlauchsensorik insbesondere zur Erfassung eines Fußgängeranpralles angeordnet ist.It For example, a vehicle is known which has a bending beam and a bumper unit wherein between the bending beam and the bumper unit an absorber element formed from a foam is arranged. In the absorber element is on a side facing the bending beam a groove introduced, in which a hose sensor, in particular for detection a pedestrian impact is arranged.
Der Erfindung liegt die Aufgabe zugrunde, ein verbessertes Fahrzeug mit einem Biegeträger und einer Stoßfängereinheit mit einem dazwischen angeordneten Absorberelement anzugeben.Of the Invention is based on the object, an improved vehicle with a bending beam and a bumper unit indicate with an absorber element arranged therebetween.

Vorteilhafte Weiterbildungen der Erfindung sind Gegenstand der Unteransprüche.advantageous Further developments of the invention are the subject of the dependent claims.
Bei einem Fahrzeug mit einem Biegeträger und einer Stoßfängereinheit ist zwischen Biegeträger und Stoßfängereinheit zumindest ein Absorberelement mit einer Sensorik angeordnet. Erfindungsgemäß ist das Absorberelement schaumfrei.at a vehicle with a bending beam and a bumper unit is between bending beam and bumper unit arranged at least one absorber element with a sensor. This is according to the invention Absorber element foam-free.
Dadurch, dass das Energie absorbierende Absorberelement nicht aus Schaum gebildet ist, ist ein Bauraum zur Anordnung des Absorberelementes in vorteilhafter Weise reduziert. Darüber hinaus ist mittels des Absorberelementes ein passiver Fußgängerschutz optimiert, wobei die Funktion der Sensorik sichergestellt ist. Ferner ist das Gewicht des Fahrzeuges vermindert, wodurch Kraftstoffverbrauch im Fahrzeugbetrieb und somit CO2-Ausstoß verringert sind.The fact that the energy absorbing absorber element is not formed from foam, a space for the arrangement of the absorber element is reduced in an advantageous manner. In addition, a passive pedestrian protection is optimized by means of the absorber element, wherein the function of the sensor system is ensured. Furthermore, the weight of the vehicle is reduced, whereby fuel consumption in vehicle operation and thus CO 2 emissions are reduced.
Weiterhin treten bei dem erfindungsgemäßen Fahrzeug vergleichsweise geringe Schäden bei so genannten Parkremplern auf.Farther occur in the vehicle according to the invention comparatively low damage at so-called parking bumps on.
Beispielsweise kann die Sensorik, die vorzugsweise als Schlauchsensorik ausgeführt ist, Bestandteil einer Fußgängerschutzvorrichtung sein, wobei mittels der Sensorik auch andere Lebewesen und/oder Hindernisse, an die das Fahrzeug, z. B. bei einem Einparkvorgang prallt oder die an das Fahrzeug prallen, erfassbar sind.For example can the sensor, which is preferably designed as a hose sensor, Part of a pedestrian protection device be, by means of the sensor also other living beings and / or Obstacles to which the vehicle, eg. B. at a parking operation bounces or bounce on the vehicle, are detectable.

Die Stoßfängereinheit als solche erstreckt sich üblicherweise über eine Breite des Frontbereiches, wobei eine Karosserie des Fahrzeuges mittels der Stoßfängereinheit so geschützt werden soll, dass Kollisionen bei niedrigen Geschwindigkeiten keine oder nur geringe Beschädigungen an dem Fahrzeug zur Folge haben. Darüber hinaus dient die Stoßfängereinheit als Aufnahmeelement für Funktionsbauteile, wie z. B. Scheinwerfer und Abstandssensoren. Ferner dient die Stoßfängereinheit auch dem Schutz von unfallbeteiligten Personen.The bumper unit as such usually extends over one Width of the front area, being a bodywork of the vehicle by means of the bumper unit so protected should be that collisions at low speeds no or only minor damage on the vehicle result. In addition, the bumper unit serves as a receiving element for Functional components, such as. B. headlights and distance sensors. Further serves the bumper unit also the protection of accident-related persons.
