The Zündsatz recording (3) and the dry pad are integrally molded from a material in which the desiccant is included.
Description
Die Erfindung betrifft eine Gasgeneratorbaugruppe für ein Airbagmodul eines Kraftfahrzeugs nach dem Oberbegriff des Anspruchs 1. The invention relates to a gas generator assembly for an airbag module of a motor vehicle according to the preamble of claim 1.
Eine derartige Gasgeneratorbaugruppe umfasst eine Zündeinrichtung zum Aktivieren der Gasgeneratorbaugruppe mit einem Zündsatz, der bei Aktivierung der Gasgeneratorbaugruppe mittels eines Anzünders der Zündeinrichtung gezündet wird, um ein Gas zu erzeugen, mit dem ein Gassack des Airbagmoduls aufblasbar ist, und der in einer Zündsatz-Aufnahme der Zündeinrichtung aufgenommen ist. In der Gasgeneratorbaugruppe ist weiterhin ein Trockenkissen angeordnet, dass ein Trockenmittel zum Reduzieren der Feuchtigkeit in der Gasgeneratorbaugruppe enthält. Such a gas generator assembly comprises an ignition device for activating the gas generator assembly with a primer which is ignited upon activation of the gas generator assembly by means of a detonator of the ignition device to produce a gas with which a gas bag of the airbag module is inflatable, and in a Zündsatz- recording the Ignition device is added. The gas generator assembly further includes a dry pad that includes a desiccant to reduce moisture in the inflator assembly.
Eine solche Gasgeneratorbaugruppe ist aus der
Der Erfindung liegt das Problem zugrunde, eine Gasgeneratorbaugruppe der eingangs genannten Art hinsichtlich ihres Aufbaus und ihrer Montierbarkeit weiter zu verbessern. The invention is based on the problem of further improving a gas generator assembly of the type mentioned above with regard to its construction and its mountability.
Dieses Problem wird erfindungsgemäß durch die Schaffung einer Gasgeneratorbaugruppe mit den Merkmalen des Patentanspruchs 1 gelöst. This problem is solved according to the invention by the creation of a gas generator assembly having the features of patent claim 1.
Danach ist das Trockenkissen zusammen mit der Zündsatz-Aufnahme einstückig aus einem Material geformt, in welchem das Trockenmittel enthalten ist. Thereafter, the dry pad is formed integrally with the Zündsatz recording from a material in which the desiccant is contained.
Hierdurch wird die Anzahl der erforderlichen Bauteile der Gasgeneratorbaugruppe reduziert und deren Montage vereinfacht. As a result, the number of required components of the gas generator assembly is reduced and simplifies their assembly.
Der Anzünder der Zündeinrichtung, mittels dem bei Aktivierung der Gasgeneratorbaugruppe der Zündsatz gezündet wird, ragt in einer Ausführungsform in die Zündsatz-Aufnahme hinein und ist von dieser umgeben. Hierzu kann die Zündsatz-Aufnahme im Querschnitt ringförmig ausgeführt sein und eine ringförmig umlaufende Außenwand bilden. Gemäß einer Weiterbildung dieser Ausführungsform steht von der Innenseite der ringförmig umlaufenden Außenwand der Zündsatz-Aufnahme ein einstückig hieran angeformter Stützabschnitt ab, an dem sich der Anzünder innerhalb der Zündsatz-Aufnahme abschnittsweise abstützt. The lighter of the ignition device, by means of which the ignition set is ignited when the gas generator assembly is activated, in one embodiment projects into and is surrounded by the ignition charge receptacle. For this purpose, the Zündsatz recording in cross-section may be annular and form an annular peripheral outer wall. According to a development of this embodiment is from the inside of the annular peripheral outer wall of the Zündsatz recording a integrally molded thereto support portion from where the lighter within the Zündsatz recording partially supported.
An der Zündsatz-Aufnahme kann weiterhin eine Trennwand angeordnet sein, und insbesondere einstückig angeformt sein, mittels der der mit dem Zündsatz befüllte Innenraum der Zündsatz-Aufnahme von einer weiteren Kammer der Gasgeneratorbaugruppe getrennt ist, insbesondere von einer Brennkammer der Gasgeneratorbaugruppe, in welcher eine pyrotechnische Ladung enthalten ist, die bei Aktivierung der Gasgeneratorbaugruppe und eine hiermit einhergehenden Zündung des Zündsatzes zur Bildung eines Gases verbrennt. At the Zündsatz recording further a partition can be arranged, and in particular be integrally formed, by means of which filled with the Zündsatz interior of the Zündsatz recording is separated from another chamber of the gas generator assembly, in particular of a combustion chamber of the gas generator assembly in which a pyrotechnic Charge is included, which burns upon activation of the gas generator assembly and an associated ignition of the ignition charge to form a gas.
Damit die Zündeinrichtung bei Aktivierung der Gasgeneratorbaugruppe und der hiermit einhergehenden Zündung des Zündsatzes auf eine in der weiteren Kammer angeordnete pyrotechnische Ladung einwirken kann, sodass diese verbrennt, weist die besagte Trennwand mindestens eine Durchtrittsöffnung auf. Eine jeweilige Durchtrittsöffnung soll bis zum Aktivieren der Gasgeneratorbaugruppe verschlossen sein und erst bei Zündung des Zündsatzes freigegeben werden. Hierzu kann an der Zündsatz-Aufnahme mindestens ein flächiges Dichtelement einstückig angeformt sein, welches die Durchtrittsöffnung verschließt und welches bei Aktivierung der Gasgeneratorbaugruppe und der damit einhergehenden Zündung des Zündsatzes zerstört wird. So that the ignition device can act upon activation of the gas generator assembly and the associated ignition of the ignition charge on a pyrotechnic charge arranged in the further chamber, so that it burns, said partition has at least one passage opening. A respective passage opening should be closed until activation of the gas generator assembly and released only when the ignition set. For this purpose, at least one planar sealing element may be integrally formed on the Zündsatz recording, which closes the passage opening and which is destroyed upon activation of the gas generator assembly and the associated ignition of the Zündsatzes.
Die Zündsatz-Aufnahme und das Trockenkissen können insbesondere einstückig aus einem ein Trockenmittel enthaltenden synthetischen Polymer, insbesondere Silikon (Polyorganosiloxan), geformt sein. Als Trockenmittel können dabei z.B. Kalziumoxid, Kalziumsulfat oder Zeolithe vorgesehen sein. The primer and the dry pad may in particular be integrally molded from a desiccant-containing synthetic polymer, in particular silicone (polyorganosiloxane). As desiccant, e.g. Calcium oxide, calcium sulfate or zeolites may be provided.
