Der Erfindung liegt die Aufgabe zugrunde, eine gegenüber dem Stand der Technik verbesserte Gurtstraffvorrichtung zur Straffung eines Gurtbandes eines Sicherheitsgurtes anzugeben.The invention has for its object to provide a comparison with the prior art improved belt tensioning device for tightening a belt of a seat belt.
Die Aufgabe wird erfindungsgemäß durch die in Anspruch 1 angegebenen Merkmale gelöst.The object is achieved by the features specified in claim 1.
Vorteilhafte Ausgestaltungen der Erfindung sind Gegenstand der Unteransprüche.Advantageous embodiments of the invention are the subject of the dependent claims.
Eine Gurtstraffvorrichtung ist zur Straffung eines Gurtbandes eines Sicherheitsgurtes bei einer Verunfallung oder einer drohenden Verunfallung eines Fahrzeuges vorgesehen, wobei die Gurtstraffvorrichtung erfindungsgemäß zumindest ein ferromagnetisches Element, das an einem an einem Gurtschloss angeordneten Gurtseil befestigt ist, und zumindest einen fahrzeugfest angeordneten Elektromagnet, welcher zur Gurtstraffung bestrombar ist, aufweist.A belt tensioning device is provided for tightening a webbing of a safety belt in an accident or impending accident of a vehicle, wherein the belt tensioning device according to the invention at least one ferromagnetic element which is attached to a seat belt buckle arranged on a belt, and at least one fixedly mounted electromagnet, which for belt tightening is energized.
Eine solche Gurtstraffvorrichtung ist vergleichsweise einfach aufgebaut und mittels nur eines Aggregates reversibel sowohl als Schutzmaßnahme vor einer drohenden Verunfallung als auch bei einer Verunfallung des Fahrzeuges auslösbar. Zudem ist es möglich, eine Straffkraft in Abhängigkeit eines durch die Verunfallung bedingten Lastfalles oder insassenabhängig einzustellen, wobei keines der Teile der Gurtstraffvorrichtung zerstört wird, so dass diese wieder verwendbar sind.Such a belt tensioning device is comparatively simple and reversible by means of only one unit both as a protective measure against an impending accident as well as an accident of the vehicle triggered. In addition, it is possible to set a tensioning force as a function of a casualty caused by the accident or occupant dependent, with none of the parts of the belt tensioning device is destroyed, so that they are reusable.
Darüber hinaus entsteht bei der Auslösung der Gurtstraffvorrichtung kein Rauch, so dass keine Geruchsbelästigung für Fahrzeuginsassen auftreten kann.In addition, no smoke is generated when the belt tensioning device is triggered, so that no odor nuisance for vehicle occupants can occur.
Handelt es sich bei dem Fahrzeug um ein Elektrofahrzeug, ein Hybridfahrzeug oder ein mit Brennstoffzellen betriebenes Fahrzeug, kann die Gurtstraffvorrichtung mit einem Energiespeicher verbunden sein, in welchem elektrische Energie gespeichert ist.If the vehicle is an electric vehicle, a hybrid vehicle or a vehicle powered by fuel cells, the belt tensioning device may be connected to an energy store in which electrical energy is stored.
Ausführungsbeispiele der Erfindung werden im Folgenden anhand von Zeichnungen näher erläutert.Embodiments of the invention are explained in more detail below with reference to drawings.
