Abstract
Description
Die Erfindung betrifft einen Seitengassack für ein Fahrzeuginsassen-Rückhaltesystem nach dem Oberbegriff des Anspruchs 1 und ein Seitengassack-Modul für eine Fahrzeuginsassen-Schutzeinrichtung.The The invention relates to a side airbag for a vehicle occupant restraint system according to the preamble of claim 1 and a side airbag module for a vehicle occupant protection device.
Bei Seitengassäcken, insbesondere bei Seitengassäcken, die zusammengefaltet in einem im Bereich der Dachkante des Fahrzeugs angeordneten Gassack-Modul untergebracht sind, können beim Befüllen des Gassacks Beschädigungen an dessen Einblasmund auftreten, wenn das Faltenpaket nicht schnell genug auseinandergeschoben wird. Die Beschädigungen sind auf die anfänglich sehr hohen Temperaturen des Gases, das von einem Gasgenerator bereitgestellt wird, und den hohen Gasstrom zurückzuführen.at Side airbags, especially for side airbags, which folded in one in the area of the roof edge of the vehicle arranged gas bag module can be accommodated when filling the Gas bag damage at the Einblasmund occur when the fold package is not fast enough is pushed apart. The damages are very bad at first high temperatures of the gas provided by a gas generator is due, and the high gas flow.
Ein Seitengassack mit den Merkmalen des Oberbegriffs des Anspruchs 1 ist aus der DE-U-201 05 734 bekannt. Im Inneren dieses Gassacks ist eine textile Schutzlage angeordnet, die das aus dem Gasgenerator ausströmende heiße Gas umlenkt und aufteilt, um ein direktes Anströmen der Wandungen des Gassacks zu vermeiden.One Side airbag having the features of the preamble of claim 1 is known from DE-U-201 05 734. Inside this gas bag is a textile protective layer arranged, which from the gas generator outflowing name is Gas deflects and divides, to a direct flow against the walls of the gas bag to avoid.
Die Erfindung schafft einen Seitengassack, der insbesondere im Anfangsstadium der Entfaltung ein schnelles Auseinanderschieben des gefalteten Gassackpakets gewährleistet.The Invention provides a side airbag, especially in the initial stage the unfolding a quick sliding apart of the folded airbag package guaranteed.
Gemäß der Erfindung ist bei einem Seitengassack der eingangs genannten Art der Beutel mit einer Reißnaht versehen, die bei einem vorbestimmten Innendruck des Beutels aufreißt und dadurch eine Ausströmöffnung freigibt. Der Beutel dient als anfängliche Entfaltungshilfe für den zusammengelegten Gassackmantel. Durch das Aufblasen und das dadurch bedingte Aufblähen des Beutels, wird das den Beutel umgebende Faltenpaket des Gassackmantels auf effektive Weise in kürzester Zeit auseinandergeschoben.According to the invention is in a side airbag of the type mentioned the bag with a tear seam provided, which ruptures at a predetermined internal pressure of the bag and thereby a Outflow opens. The bag serves as an initial Development aid for the folded gas bag mantle. By inflating and thereby conditional puffing of the bag, which is the bag surrounding fold package of the gas bag mantle effectively in the shortest possible time Time apart.
Eine gezielte Beeinflussung des Aufblasverhaltens des Gassacks wird dadurch erreicht, daß der Beutel erfindungsgemäß mit einer Reißnaht versehen ist, die bei einem vorbestimmten Innendruck des Beutels aufreißt und dadurch eine Ausströmöffnung freigibt. So ist gewährleistet, daß das heiße Gas zunächst im Beutel aufgefangen wird, bevor es in abgekühlter Form durch die vorher verschlossene Ausströmöffnung in das Volumen des Gassackmantels gelangt. Mögliche Risse im Einblasbereichs des Gassacks oder ein Durchbrennen werden dadurch verhindert.A targeted influencing the inflation of the gas bag is characterized achieved that the bag according to the invention with a tear seam is provided at a predetermined internal pressure of the bag ruptures and thereby releases an outflow opening. This ensures that that this name is Gas first is caught in the bag before being cooled in the previous closed outflow opening in the volume of the gas bag mantle arrives. Possible cracks in the blowing area of the gas bag or burn through are prevented.
Gemäß einer bevorzugten Ausführungsform weist der Beutel eine längliche Gestalt auf mit einem ersten Ende, das als Einblasöffnung ausgebildet ist, und einem zweiten Ende, das als Ausströmöffnung ausgebildet ist. Die Einblasöffnung kann direkt mit einem Einblasstutzen verbunden werden, über den das von einem Gasgenerator bereitgestellte Gas zugeführt wird. Somit wird das Gas zunächst in den Beutel geleitet, bevor er durch die Ausströmöffnung in das Volumen des Gassackmantels einströmt und den Gassack vollständig entfaltet.According to one preferred embodiment the bag is an oblong Shape up with a first end, which is designed as a blow-in is, and a second end, which is designed as a discharge opening. The inflation opening can be connected directly to an inlet nozzle over which the supplied by a gas generator gas is supplied. Thus, the gas becomes first passed into the bag before passing through the discharge opening the volume of the gas bag mantle flows in and unfolds the gas bag completely.
Die Erfindung sieht ferner ein Seitengassack-Modul mit wenigstens einem erfindungsgemäßen Seitengassack vor. Vorzugsweise ist der Beutel des Seitengassacks direkt mit einem Einblasstutzen des Moduls verbunden.The The invention further provides a side airbag module having at least one side airbag according to the invention in front. Preferably, the bag of the side airbag is directly with a Connected inlet of the module.
Weitere Merkmale und Vorteile der Erfindung ergeben sich aus der folgenden Beschreibung und aus der beigefügten Zeichnung, auf die bezug genommen wird. In der Zeichnung zeigt die einzige Figur eine Querschnittsansicht eines erfindungsgemäßen Seitengassack-Moduls mit zwei erfindungsgemäßen Seitengassäcken im entfalteten Zustand.Further Features and advantages of the invention will become apparent from the following Description and from the attached Drawing to which reference is made. In the drawing shows the single figure is a cross-sectional view of a side airbag module according to the invention with two side airbags according to the invention in unfolded state.
