Die Aufgabe der Erfindung besteht darin, einen Gurtstraffer für ein Sicherheitsgurtsystem bereitzustellen, der sich durch eine einfache Bauweise sowie durch eine vereinfachte Abdichtung auszeichnet.The The object of the invention is a belt tensioner for To provide a safety belt system that is characterized by a simple Design and characterized by a simplified seal.
Zu diesem Zweck sieht die Erfindung einen Gurtstraffer für ein Sicherheitsgurtsystem vor mit einem Straffergehäuse, einer Antriebseinheit und einem durch die Antriebseinheit bewegten Kraftübertragungsmittel, wobei zwischen der Antriebseinheit und dem Kraftübertragungsmittel ein Multifunktionsteil vorgesehen ist, das von der Antriebseinheit weg gegen das Kraftübertragungsmittel bewegbar ist, und wobei das Multifunktionsteil einen Ventilabschnitt und einen am Straffergehäuse angreifenden Dichtabschnitt aufweist. Beim erfindungsgemäßen Gurtstraffer wird also eine Dichtung zwischen der Antriebseinheit und dem Kraftübertragungsmittel vorgesehen, weshalb der Raum zwischen der Antriebseinheit und dem Kraftübertragungsmittel abgedichtet ist. Der Dichtabschnitt ist Teil des Multifunktionsteils und ist im Straffergehäuse beweglich angeordnet. Das von der Antriebseinheit erzeugte Druckgas bewegt das Multifunktionsteil von der Antriebseinheit weg, und das Multifunktionsteil schiebt das Kraftübertragungsmittel von der Antriebseinheit weg. Der Dichtabschnitt ist dabei nicht in einem im Straffergehäuse aufgenommenen Kolben vorgesehen, sondern an einem direkt am Straffergehäuse angreifenden Multifunktionsteil.To For this purpose, the invention provides a belt tensioner for a safety belt system with a tensioner housing, a drive unit and a moving by the drive unit Power transmission means, wherein between the drive unit and the power transmission means provided a multi-functional part is that of the drive unit away against the power transmission means is movable, and wherein the multifunction part is a valve section and a tightening section engaging the tightener housing having. In the belt tensioner according to the invention So is a seal between the drive unit and the power transmission means provided, which is why the space between the drive unit and the Power transmission means is sealed. The sealing section is part of the multifunction part and is in the Straffergehäuse movably arranged. The compressed gas generated by the drive unit moves the multifunction part away from the drive unit, and that Multifunction part pushes the power transmission means away from the drive unit. The sealing section is not provided in a piston accommodated in the Straffergehäuse, but on a right on the penalty box attacking Multifunction part.
Vorzugsweise besitzt das Multifunktionsteil im nicht aktivierten Zustand eine Auslaßöffnung. Über die Auslaßöffnung kann Druckgas aus dem zwischen der Antriebseinheit und dem Multifunktionsteil gebildeten Druckraum ausströmen, so daß das Druckgas nach dem Straffen aus Sicherheitsgründen langsam abströmen kann.Preferably the multifunction part has a non-activated state Outlet. About the outlet can compressed gas from the formed between the drive unit and the multifunction part Pressure chamber flow, so that the pressurized gas after for safety reasons, slowly exude the tightening can.
Insbesondere ist ein Berstmittel in Form einer Berstscheibe vorgesehen. Das Berstmittel verschließt einen Kanal, über den Gas aus dem Druckraum ausströmen kann, und kann ab einem bestimmten Gasdruck im Druckraum bersten. Damit ist gewährleistet, daß oberhalb eines vorbestimmten Gasdrucks im Druckraum Gas über die Auslaßöffnung abrupt aus dem Druckraum entweichen kann. Auf diese Weise ist sichergestellt, daß auch bei einer Zündung der Treibladung im ungünstigsten Fall kein übermäßig hoher Gasdruck im Druckraum entstehen kann. Eventuell auftretende Berstflammen und/oder Heißgase bleiben deshalb innerhalb des Straffergehäuses, was die Brandgefahr minimiert.Especially a bursting means in the form of a rupture disc is provided. The bursting agent closes a channel, via the gas from the Pressure chamber can flow, and can from a certain Burst gas pressure in the pressure chamber. This ensures that that above a predetermined gas pressure in the pressure chamber Gas off abruptly through the outlet can escape the pressure chamber. In this way it is ensured that even with an ignition of the propellant in worst case no overly high gas pressure can occur in the pressure chamber. Eventually occurring Burst flames and / or hot gases therefore remain within of the tensioner housing, which minimizes the risk of fire.
In einer besonders einfachen und kostengünstigen Ausführung ist die Auslaßöffnung in dem Berstmittel vorgesehen, so daß dieses eine Doppelfunktion innehat.In a particularly simple and inexpensive design if the outlet opening is provided in the bursting means, so that this has a double function.
Das Multifunktionsteil kann aus mehreren Einzelteilen zusammengesetzt sein, wobei der Dichtabschnitt an einem Dichtkörper und der Ventilabschnitt an einem Ventilkörper vorgesehen ist. Die einzelnen Teile (Dichtkörper und Ventilkörper) werden gesondert hergestellt und anschließend mittels eines geeigneten Verfahrens zu einem Multifunktionsteil zusammengesetzt. Sie können somit aus unterschiedlichen Materialien bestehen.The Multifunction part can be composed of several individual parts be, wherein the sealing portion of a sealing body and the valve portion is provided on a valve body. The individual parts (sealing body and valve body) are prepared separately and then by means of a suitable Procedure to a multifunction part composed. You can thus consist of different materials.
Insbesondere ist das Berstmittel mit dem Ventilkörper verpreßt. Das Verpressen des Berstmittels und des Ventilkörpers ist einfach und kostengünstig. Auch kann das Berstmittel in den Ventilkörper einrolliert werden. Natürlich sind auch andere Befestigungsarten denkbar.Especially the bursting agent is pressed with the valve body. The compression of the bursting means and the valve body is easy and inexpensive. Also, the bursting agent in rolled up the valve body. Naturally Other types of attachment are conceivable.
Der Ventilkörper kann einen Kanal haben, der auf der von der Antriebseinheit abgewandten Seite in Schlitzen ausläuft. Über den Kanal und die Schlitze strömt das Gas nach vorne, also in Richtung des Kraftübertragungsmittels. Die Schlitze sind zum Beispiel kreuz- oder sternförmig.The valve body may have a channel which terminates in slots on the side remote from the drive unit. Through the channel and the slots, the gas flows forward, ie in the direction of the power transmission means. The slots are, for example, cross-shaped or star-shaped.
Vorzugsweise ist der Dichtabschnitt ein sich in Richtung Antriebseinheit seitlich zunehmend nach außen erstreckender Randabschnitt des Dichtkörpers. Der elastische Dichtabschnitt kann sich dem Verlauf des Straffergehäuses anpassen und Schwankungen des Innendurchmessers des Straffergehäuses ausgleichen, weshalb kaum noch Leckageströme auftreten.Preferably the sealing portion is a laterally towards the drive unit increasingly outwardly extending edge portion of the sealing body. The elastic sealing portion may be the course of the tensioner housing adjust and variations in the inside diameter of the tensioner housing compensate, which is why hardly any leakage currents occur.
Insbesondere sind der Dichtkörper und der Ventilkörper über einen in eine Ausnehmung hineinragenden Vorsprung miteinander verbunden und zueinander zentriert. Der Ventilkörper wird so zum Dichtkörper ausgerichtet, daß er nicht am Straffergehäuse angreift, weshalb keine Reibung zwischen dem Ventilkörper und dem Straffergehäuse auftritt.Especially are the sealing body and the valve body over a projecting into a recess projection connected together and centered on each other. The valve body is thus the sealing body Aligned that he is not at the Straffergehäuse attacks, which is why there is no friction between the valve body and the Straffergehäuse occurs.
