Abstract

Allgemein bekannt ist ein Anschlagpuffer, der ausschließlich als Gummibauteil ausgebildet ist, das relativ weich eingestellt ist und an einem Ende ein Außengewinde zum Eindrehen in ein Loch eines Blechbauteils besitzt. Solche Anschlagpuffer dienen beispielsweise dazu, eine Kofferraumklappe von Kraftfahrzeugen beim Schließen gegenüber der restlichen Karosserie so abzustützen, dass die Kofferraumklappe nicht auf der restlichen Karosserie aufschlagen kann. Aufgabe der Erfindung ist es, einen Anschlagpuffer zu schaffen, der elastische Eigenschaften hat, die von der Umgebungstemperatur möglichst unabhängig sind. DOLLAR A Erfindungsgemäß besteht ein Anschlagpuffer (2) für eine Fahrzeugtür oder Fahrzeugklappe (1) aus einem Grundkörper (3) aus einem elastischen Material, wobei sich in dem Grundkörper (3) zumindest ein Hohlraum (5, 6) befindet, der mit einer Flüssigkeit gefüllt ist. Ein Anschlagpuffer (2), der nur aus einem elastischen Material besteht, weist normalerweise in Abhängigkeit von der Temperatur stark variierende Eigenschaften auf. Um von den Eigenschaften des elastischen Materials relativ unabhängig zu sein, weist der erfindungsgemäße Anschlagpuffer (2) zumindest einen Hohlraum (5, 6) auf, der mit einer Flüssigkeit oder einem einer Flüssigkeit ähnlichem Material gefüllt ist.
