Seitengassäcke weisen im Vergleich zu ihrer Tiefe eine relativ große Länge und Breite auf, und es steht in der Regel sehr wenig Zeit für ihre Entfaltung und Befüllung zur Verfügung. Hierdurch ist es wesentlich schwieriger ein befriedigendes Entfaltungs-, Positionierungs- und Füllverhalten als beispielsweise bei einem Frontgassack zu erreichen.Side airbags point a relatively large length and width compared to their depth, and it stands usually very little time for their unfolding and filling to disposal. This makes it much more difficult to achieve a satisfactory unfolding, positioning and filling behavior as to reach for example in a front airbag.
Die vorliegende Erfindung stellt sich deshalb die Aufgabe, eine Seitengassack-Einheit dahingehend zu verbessern, dass Enfaltungs-, Positionierungs- und Füllverhalten verbessert wird.The The present invention therefore has for its object, a side airbag unit to improve the unfolding, positioning and filling behavior is improved.
Diese Aufgabe wird durch eine Seitengassack-Einheit mit den Merkmalen des Anspruchs 1 gelöst.These Task is by a side airbag unit with the features of claim 1.
Der Gassack der erfindungsgemäßen Gassack-Einheit weist eine sich zwischen zwei Wänden befindende Hauptkammer und eine außerhalb dieser Hauptkammer zwischen einer Wand der Hauptkammer und einer weiteren Wand angeordnete Nebenkammer auf, wobei die Nebenkammer ein kleineres Volumen als die Hauptkammer hat. Bei Betätigung des Gasgenerators strömt von diesem das Gas zunächst in die Nebenkammer und von dort über wenigstens eine Überströmöffnung in die Hauptkammer. Die Nebenkammer dient also als Füllkammer für die Hauptkammer.Of the Airbag of the gas bag unit according to the invention has a located between two walls Main chamber and one outside this main chamber between a wall of the main chamber and a additional wall arranged on the side chamber, wherein the secondary chamber has a smaller volume than the main chamber. Upon actuation of the Gas generator flows from this the gas first in the side chamber and from there over at least one overflow opening in the main chamber. The secondary chamber thus serves as a filling chamber for the main chamber.
Aufgrund des relativ geringen Volumens der Füllkammer wird diese nach Zündung des Gasgenerators sehr schnell gefüllt und entfaltet sich in ihre Endposition. Hierbei zieht sie die Hauptkammer mit, wodurch auch deren Entfaltungs- und Positionierungsvorgang unterstützt, präzisiert und beschleunigt wird. Nach Abschluss der vollständigen Befüllung des Gassacks verliert die Nebenkammer in der Regel ihre Funktion.by virtue of the relatively small volume of the filling chamber is this after ignition of the Gas generator filled very quickly and unfolds into its final position. Here she pulls the main chamber with, thereby also their unfolding and positioning process support clarified and is accelerated. After completion of the complete filling of the gas bag loses the auxiliary chamber usually their function.
Die Nebenkammer hat neben der Verbesserung des Expansionsverhaltens die weitere Aufgabe, dafür zu sorgen, dass in unterschiedlichen Schutzkammern der Hauptkammer, hierbei handelt es sich um eine Becken- und eine Thoraxkammer, unterschiedliche Drücke aufgebaut und insbesondere auch aufrechterhalten werden. Hierzu sind die wenigstens zwei Schutzkammern nicht unmittelbar, sondern ausschließlich über die Nebenkammer strömungstechnisch miteinander verbunden.The Secondary chamber has besides the improvement of the expansion behavior the further task, for that to ensure that in different protective chambers of the main chamber, this is a pelvic and thoracic chamber, different pressures built up and, in particular, maintained. For this the at least two protective chambers are not immediate but exclusively via the Secondary chamber fluidic connected with each other.
Nach Abschluss des Füllvorganges und/oder bei Eintauchen des Insassen in den Gassack wird ein Teil der Überströmöffnungen geschlossen, so dass nur ein gerichteter Gasaustausch zwischen den Schutzkammern stattfinden kann. Hierzu dienen flexible Lappen, die zumindest einen Teil der Überströmöffnungen auf der Seite der Hauptkammer abdecken. Hierdurch kann erreicht werden, dass in einer Beckenkammer ein größerer Druck aufgebaut und aufrecht erhalten werden kann als in einer Thoraxkammer.To Completion of the filling process and / or immersion of the occupant in the gas bag becomes a part the overflow openings closed, leaving only a directed gas exchange between the protective chambers can take place. This purpose is served by flexible cloths, which at least one Part of the overflow openings cover on the side of the main chamber. This can be achieved be that built up in a pelvic chamber, a greater pressure and upright can be obtained as in a thorax chamber.
