Abstract

The system has a steel bush (4) suspended on a section of a tube gas generator (1). The bush is arranged around a solid gas generator that is mounted on the generator (1). A power train is covered with an inhibitor. A lighter is provided with a rebound unit so that required gas flows through a nozzle and not through the tube gas generator. A combustor is locked through spikes.

Description

Die Erfindung betrifft ein Gaserzeugersystem für den Kopf-Seiten-Airbag welches dafür sorgt, dass der Airbag nicht nur beim ersten Aufprall einen wirksamen Schutz bietet, d.h. prall gefüllt ist, sondern auch noch während der Fahrzeug-Überschlagphase für einen ausreichend gefüllten Airbag sorgt. Das Gaserzeugersystem muss im Millisekundenbereich funktionieren und einen Zeithorizont von fünf Sekunden aufweisen.The The invention relates to a gas generating system for the head-side airbag which makes sure that the airbag not only effective protection on the first impact offers, i. filled up is, but still during the vehicle rollover phase for one sufficiently filled Airbag provides. The gas generant system must operate in the millisecond range and a time horizon of five Seconds.

Derartige Gaserzeugersysteme sind bekannt, z.B. DE 100 46 701.6 und US 2003/0075 904 A1.Such gas generant systems are known, for example DE 100 46 701.6 and US 2003/0075904 A1.

Die eingesetzten Systeme haben den Nachteil, dass sie entweder aus der Kombination Schlauchgasgenerator und Hochdruckflasche bestehen oder ein Tandem aus Schlauchgasgenerator und Feststoffgasgenerator bilden.The used systems have the disadvantage that they either from the Combination hose gas generator and high pressure bottle exist or form a tandem of hose gas generator and solid gas generator.

Die Aufgabe der vorliegenden Erfindung ist es das Gaserzeugersystem universeller zu machen, d.h., dass der Schlauchgasgenerator alleine verwendbar ist, und falls gewünscht, durch zusätzliche Komponenten für die Rollover Anforderung aufgerüstet werden kann.The Object of the present invention is the gas generator system making it more universal, that is to say, the hose gas generator alone is usable, and if desired, through additional components for the Rollover requirement upgraded can be.

Die Aufgabe wird erfindungsgemäß dadurch gelöst, indem der 5s-Feststoffgasgenerator auf den 15ms-Schlauchgasgenerator aufgesteckt wird.The Task is inventively achieved by the 5s solid gas generator is attached to the 15ms inflator becomes.

Die Erfindung wird im folgenden anhand einer Zeichnung erläutert.The Invention will be explained below with reference to a drawing.

Die 1 zeigt ein Ausführungsbeispiel der Erfindung.The 1 shows an embodiment of the invention.

Zunächst wird der Schlauchgasgenerator 1 präpariert indem die Büchse 4 im Anfangsbereich aufgeschoben wird die den Schlauch schützt und die anfänglichen Löcher abdeckt sowie als Klemme dient. Weiter wird die Aufladung 5 und die Rückschlageinheit 6 eingesetzt.First, the hose gas generator 1 Prepared by the sleeve 4 is pushed in the initial area which protects the hose and covers the initial holes and serves as a clamp. Next is the charge 5 and the kickback unit 6 used.

Dann wird der Treibsatz 7 nebst Abstandshalter 8 darüber geschoben und die Brennkammer 9 übergestülpt und durch Stifte 10 verriegelt.Then the propellant 7 along with spacers 8th pushed over it and the combustion chamber 9 slipped over and through pins 10 locked.

Da das heiße aus der Düse 12 in den Airbag 13 einströmende Gas einer sehr raschen Abkühlungsfunktion unterliegt ist der Treibsatz 7 anteilig mit einem Inhibitor 11 versehen, der dafür sorgt, dass der Treibsatz 7 nicht auf einmal sondern im Interwall abbrennt, d.h., dass das Nachförderprinzip gegeben ist.Because the hot from the nozzle 12 in the airbag 13 inflowing gas is subject to a very rapid cooling function is the propellant 7 proportionate with an inhibitor 11 provided that ensures that the propellant 7 not at once but in the interwall burns, ie, that the Nachförderprinzip is given.
