SeitengassackmodulSide airbag module
Die Erfindung betrifft ein Seitengassackmodul für ein Fahrzeuginsassen-Rückhaltesystem, mit einem Gassack und einer separaten, im Gassack angeordneten Gasführung.The invention relates to a side gas bag module for a vehicle occupant restraint system, with a gas bag and a separate gas guide arranged in the gas bag.
Eine solche Gasführung wird eingesetzt, um das Befüllen eines langgestreckten Seitengassacks zu erleichtern. Bisherige Gasführungen weisen zumindest abschnittsweise ein starres Rohr, eine sogenannte Gaslanze, auf. Das Faltungsverfahren des Gassacks muß darauf abgestellt sein und ist entsprechend aufwendig. Darüber hinaus gibt es als Gasführung wirkende abgenähte Bereiche am Gassack, die mit allen Kammern in Strömungsverbindung stehen. Hierbei sind die Gasführungen aber nicht separate Teile, vielmehr werden sie durch die Außenwand des Gassacks gebildet.Such a gas guide is used to make it easier to fill an elongated side gas bag. Previous gas guides have at least some sections of a rigid tube, a so-called gas lance. The folding process of the gas bag must be designed for this and is correspondingly complex. In addition, there are sewn-off areas on the gas bag that act as gas guides and are in flow connection with all chambers. However, the gas guides are not separate parts; rather, they are formed by the outer wall of the gas bag.
Die Erfindung schlägt ein Seitengassackmodul vor, bei dem die Herstellung des Gassacks vereinfacht ist, ohne die Vorteile einer gezielten Befüllung von Gassackabschnitten zu verlieren.The invention proposes a side gas bag module in which the manufacture of the gas bag is simplified without losing the advantages of targeted filling of gas bag sections.
Dies wird bei einem eingangs genannten Modul dadurch erreicht, daß die Gasführung aus einem faltbaren, flexiblen Material besteht. DieThis is achieved in the module mentioned above by the fact that the gas guide is made of a foldable, flexible material.
Gasführung kann vor dem Falten des Gassacks in diesen eingebracht werden und mit dem Gassack zusammen gefaltet werden. Auf diese Weise kann das gesamte Faltungsverfahren maschinell erfolgen. Außerdem verringert sich der Platzbedarf des Moduls bei gefaltetem Gassack.The gas duct can be inserted into the gas bag before it is folded and folded together with the gas bag. This way, the entire folding process can be carried out by machine. In addition, the space required by the module when the gas bag is folded is reduced.
Besonders vorteilhaft ist es, wenn die Gasführung als Gewebeschlauch ausgeführt ist. Bei einem einstückig gewebten Gassack kann die Gasführung z.B. durch eine viertägige Webung mit diesem zusammen hergestellt werden. Auf diese Weise verringern sich die Herstellungskosten des Gassackmoduls.It is particularly advantageous if the gas duct is designed as a fabric hose. In the case of a one-piece woven gas bag, the gas duct can be manufactured together with the gas bag, for example, by weaving it for four days. This reduces the manufacturing costs of the gas bag module.
Die Gasführung kann auch aus einem in den Gassack eingebrachten Schlauch bestehen.The gas supply can also consist of a hose inserted into the gas bag.
In einer bevorzugten Ausführung der Erfindung ist die Gasführung mit einem Gasgenerator verbunden, und der Gassack weist eine erste und eine zweite, hintereinander angeordnete Kammer auf, wobei die Gasführung bis in die zweite, weiter vom Gasgenerator entfernte Kammer ragt und nur diesen befüllt. Vorzugsweise ist der Gasgenerator mit einem Gasverteiler verbunden, der wenigstens zwei Ausströmrohre aufweist, von denen eine mit der Gasführung verbunden ist und die andere mit der ersten Kammer. Es ist vorteilhaft, wenn die Gasführung nur eine, in der zweiten Kammer angeordnete Ausströmöffnung aufweist. Auf diese Weise können beide Kammern gleichzeitig befüllt werden. Da der für die zweite Kammer bestimmte Teil des Gases durch die Gasführung geleitet wird, entsteht keine hohe Belastung für den Gassack.In a preferred embodiment of the invention, the gas duct is connected to a gas generator, and the gas bag has a first and a second chamber arranged one behind the other, with the gas duct extending into the second chamber, which is further away from the gas generator, and only filling this chamber. The gas generator is preferably connected to a gas distributor which has at least two outlet pipes, one of which is connected to the gas duct and the other to the first chamber. It is advantageous if the gas duct has only one outlet opening arranged in the second chamber. In this way, both chambers can be filled at the same time. Since the part of the gas intended for the second chamber is guided through the gas duct, there is no great load on the gas bag.
In einer vorteilhaften Ausführungsform weist der Gasverteiler zwei konzentrisch angeordnete Ausströmrohre auf. Bevorzugt ist das innere Rohr mit der Gasführung verbunden. So läßt sich ein besonders kompakter Gasverteiler realisieren.In an advantageous embodiment, the gas distributor has two concentrically arranged outflow pipes. The inner pipe is preferably connected to the gas guide. This makes it possible to create a particularly compact gas distributor.
Weitere Merkmale und Vorteile der Erfindung ergeben sich aus den Unteransprüchen sowie aus der folgenden Beschreibung eines Ausführungsbeispiels zusammen mit den beigefügten Zeichnungen. In diesen zeigen:Further features and advantages of the invention emerge from the subclaims and from the following description of an embodiment together with the accompanying drawings.

Figur 1 zeigt ein Seitengassackmodul 10 mit einem Gassack 12 mit zwei Kammern 14, 16, die über einen nicht aufblasbaren Bereich 18 miteinander verbunden sind. Der Gassack 12 ist über an seinem im eingebauten, aufgeblasenen Zustand oberen Rand angeordnete Ösen 20 an einem (nicht gezeigten) Fahrzeug, z.B. am Dachrahmen, befestigbar.Figure 1 shows a side gas bag module 10 with a gas bag 12 with two chambers 14, 16, which are connected to one another via a non-inflatable area 18. The gas bag 12 can be fastened to a vehicle (not shown), e.g. to the roof frame, via eyelets 20 arranged on its upper edge in the installed, inflated state.
Im Gassack erstreckt sich in der Nähe seines oberen Randes eine Gasführung 22. An einem Ende ist diese Gasführung 22 über einen Gasverteüer 26 mit einem Gasgenerator 24 verbunden. Das andere Ende der Gasführung erstreckt sich bis in die zweite Kammer 16 und endet in einer Ausströmöffnung 27. Vorzugsweise weist die Gasführung keine weiteren Öffnungen auf. Die Gasführung kann durch eine spezielle Webtechnik im Inneren des Gassacks hergestellt sein, so daß der Gassack in diesem Bereich viertägig ist.A gas duct 22 extends in the gas bag near its upper edge. At one end, this gas duct 22 is connected to a gas generator 24 via a gas distributor 26. The other end of the gas duct extends into the second chamber 16 and ends in an outlet opening 27. Preferably, the gas duct has no further openings. The gas duct can be produced using a special weaving technique inside the gas bag, so that the gas bag is four-layered in this area.
Über den Gasverteiler 26 wird das im Rückhaltefall vom Gasgenerator 24 erzeugte Gas auf die einzelnen Kammern 14, 16 verteilt.The gas generated by the gas generator 24 in the retention case is distributed to the individual chambers 14, 16 via the gas distributor 26.
Eine erste Ausführungsform des Gasverteilers ist in Figur 2 dargestellt. Der Gasverteiler 26 weist zwei konzentrische Rohre 28 und 30 auf. Das innere Rohr weist an seinem innerhalb des äußeren Rohrs 30 gelegenen Bereich weitere Ausströmöffnungen 32 auf. An seinem dem Gassack 12 zugewandten Ende ist das innere Rohr 28 mit der Gasführung 22 verbunden. Das äußere Rohr 30 ist mit einem Abschnitt 34 der ersten Kammer 14 verbunden. Die Verbindungen können z.B. über Schlauchschellen 36 erfolgen.A first embodiment of the gas distributor is shown in Figure 2. The gas distributor 26 has two concentric tubes 28 and 30. The inner tube has further outflow openings 32 in its area located inside the outer tube 30. At its end facing the gas bag 12, the inner tube 28 is connected to the gas guide 22. The outer tube 30 is connected to a section 34 of the first chamber 14. The connections can be made, for example, via hose clamps 36.
Der Gasverteiler 26 ist an einem Ende mit dem rohrförmigen Gasgenerator 24 verbunden. Beim Befüllen des Gassacks strömt das Gas aus dem Gasgenerator 24 in das innere Rohr 28, von wo aus ein Teil des Gases durch die Ausströmöffungen 32 in das äußere Rohr 30 und in dieThe gas distributor 26 is connected at one end to the tubular gas generator 24. When filling the gas bag, the gas flows from the gas generator 24 into the inner tube 28, from where a part of the gas flows through the outlet openings 32 into the outer tube 30 and into the

Das restliche Gas strömt durch die Gasführung 22 in die zweite Kammer 16.first chamber 14. A gas-conducting ring channel is formed around the gas guide 22, which is open downwards to the chamber 14. The remaining gas flows through the gas guide 22 into the second chamber 16.
Figur 3 zeigt eine weitere Ausführungsform eines GasverteilersFigure 3 shows another embodiment of a gas distributor
126. Dieser weist zwei annähernd parallele Ausströmrohre 128, 130 auf, von denen das eine mit der Gasführung 22 und das andere mit dem Abschnitt 34 der ersten Kammmer verbunden ist. Beim Befüllen des Gassacks 12 strömt das Gas aus dem Gasgenerator 24 in einen gemeinsamen Abschnitt 132, der die Rohre 128, 130 verbindet, und von dort über die Rohre 128, 130 in die erste und die zweite Kammer 14, 16. Die Befestigung des Abschnitts 34 sowie der Gasführung 22 kann wiederum über Schlauchschellen 36 erfolgen.126. This has two approximately parallel outlet pipes 128, 130, one of which is connected to the gas guide 22 and the other to the section 34 of the first chamber. When filling the gas bag 12, the gas flows from the gas generator 24 into a common section 132 that connects the pipes 128, 130, and from there via the pipes 128, 130 into the first and second chambers 14, 16. The section 34 and the gas guide 22 can again be attached using hose clamps 36.
