Abstract
Description
Die Erfindung betrifft eine Airbageinheit zum Einbau in ein Kraftfahrzeug nach dem Oberbegriff des Anspruchs 1.The The invention relates to an airbag unit for installation in a motor vehicle according to the preamble of claim 1.
In modernen Kraftfahrzeugen werden häufig flächige Airbags beispielsweise als Seiten- oder Vorhangairbags eingebaut. Um solche Airbags in einem Airbagmodul oder direkt im Automobil im unaufgeblasenen Zustand montieren zu können ist es meist notwendig, den Airbag mit Fixierungsmitteln zu versehen, die diesen in einer bestimmten Ruhefaltung halten. Hierzu gibt es unterschiedliche Vorgehensweisen:In Modern motor vehicles are often surface airbags, for example installed as side or curtain airbags. To such airbags in an airbag module or directly in the automobile in deflated condition to mount it is usually necessary to provide the airbag with fixatives, keeping them in a certain peace of mind. There are different approaches:

Ausgehend von diesem Stand der Technik ist es Aufgabe der Erfindung, eine Airbageinheit dahingehend weiterzubilden, dass eine Fixierung des Airbags im unaufgeblasenen Zustand mit einfachen Mitteln kostengünstig möglich wird. Weiterhin soll hierbei der Einsatz mechanischer Mittel möglich sein.outgoing From this prior art, it is an object of the invention, a Airbag unit to the effect that a fixation of the Airbags in the deflated state with simple means cost possible. Furthermore, in this case the use of mechanical means should be possible.
Diese Aufgabe wird durch eine Airbageinheit mit den Merkmalen des Anspruchs 1 gelöst.These The object is achieved by an airbag unit with the features of the claim 1 solved.
Erfindungsgemäß weisen die verwendeten Fixierungsmittel wenigstens ein Kunststoffelement mit einem Längsabschnitt und zwei Querabschnitten auf. Solche Kunststoffelemente sind beispielsweise aus der Bekleidungsbranche bekannt, wo sie zum Anbringen von Preisschildern und ähnlichem an Bekleidungsstücken verwendet werden. Solche Kunststoffelemente können mit Hilfe spezieller Vorrichtungen durch Gewebe hindurchgeschossen werden, so dass ihre Handhabung sehr einfach ist. Durch Verwendung derartiger Kunststoffelemente zur Fixierung des Airbags in einer bestimmten Ruhefaltung wird zwar die Außenhülle des Airbags beschädigt, es hat sich jedoch herausgestellt, dass diese Beschädigung so gering ist, dass sie das einwandfreie Funktionieren des Airbags nicht behindert.According to the invention the fixative used at least one plastic element with a longitudinal section and two transverse sections. Such plastic elements are made, for example The clothing industry knows where to place price tags and the like on clothing be used. Such plastic elements can with the help of special devices through tissue, so that their handling very easy. By using such plastic elements for fixing the airbag in a certain peace folding is indeed the outer shell of the Airbags damaged, However, it has been found that this damage is so low is that they are the proper functioning of the airbag not disabled.
Bevorzugte Ausführungsformen der Erfindung ergeben sich aus den Unteransprüchen und aus den nun mit Bezug auf die Figuren dargestellten Ausführungsbeispielen.preferred embodiments The invention will become apparent from the dependent claims and from the now with reference on the figures illustrated embodiments.

Es ist klar, dass die hier vorgeschlagene Art der Fixierung nicht nur bei Seiten- oder Vorhangairbags, sondern bei allen Airbags angewendet werden kann, bei denen eine entsprechende Fixierung gewünscht ist.It It is clear that the type of fixation proposed here not only used on side or curtain airbags, but on all airbags can be, in which a corresponding fixation is desired.
Insbesondere zur Fixierung von im wesentlich länglich ausgebildeten Airbags, wie Vorhang- oder Seitenairbags, wird der Einsatz von mehreren Kunststoffelementen pro Airbag sinnvoll sein.Especially for fixing substantially elongated airbags, Such as curtain or side airbags, the use of multiple plastic elements be useful per airbag.

gibt. Um das aufblasbare Gewebe der Airbags durch das Einschießen der
