Abstract
Description
Die Erfindung betrifft eine Gassackanordnung mit einem Gasgenerator und mit einem wenigstens zwei aufblasbare Gassackbereiche aufweisenden Gassack, wobei beide Gassackbereiche unter Zwischenschaltung eines T-förmigen Verbindungsstückes mit unterschiedliche Ausströmquerschnitte aufweisenden Ausströmkanälen an den Gasgenerator angeschlossen sind.The The invention relates to an airbag arrangement with a gas generator and having at least two inflatable airbag areas Airbag, both gas bag areas with the interposition of a T-shaped connector with having different Ausströmquerschnitte Outflow to the Gas generator are connected.
Eine
derartige Gassackanordnung ist beispielsweise in der
Soweit eine derartige Gassackanordnung vor ihrer Montage in einem Kraftfahrzeug gelagert und insbesondere transportiert werden muss, ist nicht auszuschließen, dass es aufgrund äußerer Einflüsse, wie beispielsweise bei einem Brandfall, zu einer unbeabsichtigten Auslösung des Gasgenerators kommen kann. Daher besteht eine Anforderung an derartige Gassackanordnungen, dass sich die Gassackanordnung in einem solchen Fall schubneutral verhält, d. h. kein eine Bewegung des Verbindungsstücks in der Gassackanordnung herbeiführender Rückstoßeffekt in der einen oder anderen Richtung eintritt. Da bei einem Einsatz eines T-förmigen Verbindungsstückes bei einer in der GB 2 390 576 A beschriebenen Gassackanordnung das T-förmige Verbindungsstück unterschiedliche Ausströmquerschnitte aufweisen muss, ist damit der Nachteil verbunden, dass die Forderung nach einer schubneutralen Auslegung der Gassackanordnung nicht eingehalten wird.So far Such an airbag assembly prior to assembly in a motor vehicle stored and in particular must be transported, can not be ruled out that it due to external influences, like For example, in case of fire, to an unintentional triggering of Gas generator can come. Therefore, there is a requirement for such Airbag arrangements that the airbag assembly in such Case repulsive behaves, d. H. no movement of the connector in the airbag assembly inducing recoil effect in one way or another. As in one use a T-shaped connector in a gas bag arrangement described in GB 2 390 576 A, the T-shaped joint different outflow cross sections must have the disadvantage that the requirement is not respected after a thrust neutral design of the airbag assembly.
Der Erfindung liegt daher die Aufgabe zugrunde, eine Gassackanordnung mit den eingangs genannten Merkmalen so einzurichten, dass trotz in eingebautem Zustand unterschiedlich wirksamer Ausströmquerschnitte der Ausströmkanäle des Verbindungsstückes sich vor dem Einbau der Gassackanordnung in ein Fahrzeug bei Auslösung des Gasgenerators keine Bewegung des Verbindungsstückes ergibt.Of the Invention is therefore the object of an airbag assembly with the features mentioned above to set up so that despite in built-in state different effective Ausströmquerschnitte the outflow of the connector itself before installing the airbag assembly in a vehicle when the gas generator is triggered no movement of the connector results.
Die Lösung dieser Aufgabe ergibt sich einschließlich vorteilhafter Ausgestaltungen und Weiterbildungen der Erfindung aus dem Inhalt der Patentansprüche, welche dieser Beschreibung nachgestellt sind.The solution This object is achieved including advantageous embodiments and further developments of the invention from the content of the claims, which read this description.
Die Erfindung sieht hierzu vor, dass zur Einstellung der unterschiedlichen Ausströmquerschnitte bei einem hinsichtlich seiner Ausströmkanäle symmetrisch aufgebauten Verbindungsstück in wenigstens einem der Ausströmkanäle des Verbindungsstücks ein dessen Querschnitt reduzierender Einsatz aus einem nicht-hitzebeständigen Material angeordnet ist.The For this purpose, the invention provides that for setting the different Outflow cross sections at one with respect to its outflow channels symmetrical constructed connector in at least one of the outflow channels of the connector its cross-section reducing insert made of a non-heat-resistant material is arranged.
Die Erfindung beruht somit auf dem Prinzip, dass bei einem symmetrisch ausgebildeten T-förmigen Verbindungsstück mittels des in dem zugeordneten Ausströmkanal angeordneten Einsatzes der jeweilige Querschnitt des betreffenden Ausströmkanals in Anpassung an die unterschiedlichen Volumina der jeweils angeschlossenen Gassackbereiche eingestellt wird. Kommt es jedoch beispielsweise bei einem Brandfall zu der angesprochenen ungewollten Auslösung des Gasgenerators, so brennt der jeweilige Einsatz in dem Ausströmkanal aufgrund der Hitzeeinwirkung ab, so dass der vollständige Strömungsquerschnitt des jeweiligen Ausströmkanals freigegeben wird. Aufgrund des symmetrischen Aufbaus des T-förmigen Verbindungsstücks heben sich die durch das Einleiten des bei Auslösung des Gasgenerators freigesetzten Gases erzeugten Rückstöße beziehungsweise Schubkräfte auf, so dass sich die Gassackanordnung in der gewünschten Weise schubneutral verhält.The Invention is thus based on the principle that in a symmetrical trained T-shaped joint by means of the arranged in the associated outflow insert the respective cross section of the respective outflow channel in adaptation to the different volumes of each connected Airbag areas is set. However, it comes for example in case of fire to the mentioned unintentional release of the Gas generator, so burns the respective use in the outflow channel due the effect of heat, so that the full flow cross-section of the respective outflow is released. Lift due to the symmetrical structure of the T-shaped connector the by releasing the released when triggered the gas generator Gases generated rebounds respectively thrusts on, so that the gas bag arrangement in the desired Way push-neutral behaves.
Nach einem ersten Ausführungsbeispiel der Erfindung ist vorgesehen, dass der Einsatz aus einem von der Außenseite des Verbindungsstückes her durch eine in der Wandung des Ausströmkanals ausgebildete Bohrung in den Ausströmkanal eingebrachten Bolzen besteht, dessen im Ausströmkanal liegender Abschnitt aus einem nicht-hitzebeständigen Material besteht.To a first embodiment The invention provides that the insert of one of the outside of the connector ago by a bore formed in the wall of the outflow channel in the discharge channel introduced bolt, whose lying in the discharge channel section made of a non-heat resistant Material exists.
Hierzu kann auch vorgesehen sein, dass der Bolzen in die Bohrung einschraubbar ist und mit seinem freien Ende in die gegenüberliegende Wandung des Verbindungsstückes reicht, wobei die in den Wandungen des Verbindungskörpers liegenden Abschnitte des Bolzens aus einem hitzebeständigen Material bestehen.For this can also be provided that the bolt can be screwed into the bore is and reaches with its free end in the opposite wall of the connector, wherein the lying in the walls of the connecting body sections of the bolt of a heat-resistant material consist.
In einer alternativen Ausführungsform kann vorgesehen sein, dass der Einsatz aus einer in den Ausströmkanal einsetzbaren Stauscheibe mit einem definierten Ausströmquerschnitt besteht, wobei in einer Weiterbildung vorgesehen sein kann, dass in die Ausströmkanäle des T-förmigen Verbindungsstücks unterschiedliche Ausströmquerschnitte aufweisende Stauscheiben eingesetzt sind.In an alternative embodiment, it can be provided that the insert consists of a baffle plate which can be inserted into the outflow channel with a defined outflow cross section, wherein it can be provided in a development that different outflow cross sections have in the outflow channels of the T-shaped connection piece Baffle plates are inserted.
Wiederum alternativ kann vorgesehen sein, dass der Einsatz aus einem in den Verbindungsbereich zwischen den Ausströmkanälen und den zentralen, an den Gasgenerator angeschlossenen Einströmkanal eingesetzten dreiarmigen Staukörper besteht.In turn Alternatively, it can be provided that the use of a in the Connection area between the discharge channels and the central, to the Gas generator connected inflow channel used three-armed baffle consists.
