Abstract
Eine Gassack-Einheit besteht aus einer einen Gasraum umgebenden Gassackhülle mit zwei im wesentlichen rechteckigen Seitenwänden, die entlang eines Randes miteinander verbunden sind, wobei in der Gassackhülle eine Öffnung vorgesehen ist, und einer Gasgeneratoreinheit mit einem außerhalb des Gassacks angeordneten Gaserzeugungsbereich und einem innerhalb des Gasraums angeordneten Ausströmbereich (32) mit wenigstens zwei schubneutral angeordneten Ausströmöffnungen, wobei die Gasgeneratoreinheit durch die Öffnung in den Gasraum ragt. Um eine asymmetrische Gasverteilung innerhalb des Gasacks erreichen zu können, sind in einem an die Öffnung anschließenden Bereich des Gasraums Gasleitmittel vorgesehen, die das einströmende Gas asymmetrisch umlenken, wobei die Gasleitmittel eine erste Verbindungslinie, entlang derer die beiden Seitenwände miteinander verbunden sind, umfassen, und wobei die Verbindungslinie und ein erster Abschnitt des Randes einen ersten Strömungskanal (25) bilden, in welchem sich der Ausströmbereich (32) befindet.A gas bag unit consists of a gas bag shell surrounding a gas space with two essentially rectangular side walls, which are connected to one another along an edge, an opening being provided in the gas bag shell, and a gas generator unit with a gas generating area arranged outside the gas bag and one inside the gas space arranged outflow area (32) with at least two thrust-neutral arranged outflow openings, wherein the gas generator unit protrudes through the opening into the gas space. In order to be able to achieve an asymmetrical gas distribution within the gas bag, gas guiding means are provided in an area of the gas space adjoining the opening, which deflect the inflowing gas asymmetrically, the gas guiding means comprising a first connecting line along which the two side walls are connected to one another, and wherein the connecting line and a first section of the edge form a first flow channel (25) in which the outflow area (32) is located.
Description
Die Erfindung betrifft eine Vorhanggassack-Einheit nach dem Oberbegriff des Anspruchs 1.The invention relates to a curtain airbag unit according to the preamble of claim 1.

Weiterhin sind in der Technik Vorhang-Gassäcke bekannt, bei denen die Gasverteilung mittels eines rohrförmigen Gewebeelements erfolgt, das nur mit seiner Oberkante mit der Gassackhülle verbunden ist und von dort frei in den Innenraum des Gassacks hineinhängt. Derartige Vorhang-Gassäcke sind beispielsweise in der

Die
In manchen Anwendungsfällen ist es auch bei einem zumeist relativ großvolumigen Vorhanggassack wünschenswert, dass dieser asymmetrisch befüllt wird. Dies kann insbesondere dann der Fall sein, wenn sich die Öffnung, durch welche der Ausströmbereich der Gasgeneratoreinheit in den Gasraum ragt, im Bereich eines Zuführabschnittes, welcher zwei Schutzabschnitte des Gassacks miteinander verbindet, liegt.In some applications, it is also desirable for a mostly relatively large curtain airbag that this is filled asymmetrically. This may be the case in particular when the opening through which the outflow region of the gas generator unit projects into the gas space lies in the region of a feed section which connects two protective sections of the gas bag.
Hiervon ausgehend stellt sich die vorliegende Erfindung die Aufgabe, eine gattungsgemäße Vorhanggassack-Einheit dahingehend weiterzubilden, dass eine asymmetrische Verteilung des Gases innerhalb des Gassacks erreicht und gleichzeitig eine punktuell hohe Belastung der Gassackhülle und Nähten vermieden werden kann.On this basis, the present invention has the object to develop a generic curtain gas bag unit to the effect that an asymmetric distribution of the gas within the airbag achieved and at the same time a point high load on the airbag shell and seams can be avoided.
Diese Aufgabe wird durch eine Vorhanggassack-Einheit mit den Merkmalen des Anspruchs 1 gelöst.This object is achieved by a curtain airbag unit with the features of claim 1.
Die erfindungsgemäße Vorhanggassack-Einheit besteht aus einem Vorhanggassack mit einer einen Gasraum umgebenden Gassackhülle mit zwei im Wesentlichen rechteckigen Seitenwänden, die entlang eines Randes miteinander verbunden sind, wobei in der Gassackhülle eine Öffnung vorgesehen ist, und einer Gasgeneratoreinheit mit einem außerhalb des Gasraums angeordneten Gaserzeugungsbereich und einem innerhalb des Gasraums angeordneten Ausströmbereich mit wenigstens zwei schubneutral angeordneten Ausströmöffnungen, wobei die Gasgeneratoreinheit durch die Öffnung in den Gasraum ragt. Der Vorhanggassack weist zwei Schutzabschnitte und einen die beiden Schutzabschnitte verbindenden Zuführabschnitt auf, wobei die Öffnung in den Zuführabschnitt mündet. In einem an die Öffnung anschließenden Bereich des Gasraums sind Gasleitmittel vorgesehen, die das einströmende Gas asymmetrisch umlenken, wobei die Gasleitmittel eine erste Verbindungslinie, entlang derer die beiden Seitenwände miteinander verbunden sind, umfassen, und wobei die erste Verbindungslinie und ein erster Abschnitt des Randes im Bereich des Zuführabschnitts einen ersten Strömungskanal bilden. Weiterhin erstreckt sich in Richtung der ersten Verbindungslinie eine zweite Verbindungslinie, entlang derer die beiden Seitenwände miteinander verbunden sind, so dass zwischen erster und zweiter Verbindungslinie ein zweiter zum ersten Strömungskanal im Wesentlichen paralleler Strömungskanal gebildet ist.The curtain airbag unit according to the invention consists of a curtain airbag with a gas bag envelope surrounding a gas space with two substantially rectangular side walls which are interconnected along an edge, wherein in the airbag shell an opening is provided, and a gas generator unit with a gas generating area arranged outside the gas space and an outflow region arranged within the gas space with at least two outflow openings arranged in a rebound-neutral manner, wherein the gas generator unit projects through the opening into the gas space. The curtain airbag has two protective sections and a feed section connecting the two protective sections, with the opening leading into the feed section. In an adjoining the opening region of the gas space Gasleitmittel are provided which deflect the incoming gas asymmetrically, the Gasleitmittel a first connecting line, along which the two side walls are interconnected, and wherein the first connecting line and a first portion of the edge in Form the supply section a first flow channel. Furthermore, extending in the direction of the first connecting line, a second connecting line, along which the two side walls are connected to each other, so that between the first and second connecting line a second flow channel substantially parallel to the first flow channel is formed.
Durch diesen zweiten Strömungskanal wird ein sehr geringer Strömungswiderstand erreicht. Die Asymmetrie des Gasflusses wird durch den Gasstrom in diesem zweiten Strömungskanal bestimmt. Hierbei kann insbesondere auch ein Effekt ausgenutzt werden, wie man ihn beispielsweise aus Wasserstrahlpumpen kennt.By this second flow channel a very low flow resistance is achieved. The asymmetry of the gas flow is determined by the gas flow in this second flow channel. In this case, in particular, an effect can be exploited, as known for example from water jet pumps.

Die eben beschriebene Ausführungsform der Erfindung, welche zwei zueinander parallele Strömungskanäle aufweist, zeichnet sich dadurch aus, dass der Strömungswiderstand nur wenig erhöht werden muss. Insbesondere kann es vermieden werden, dass einer der Gasströme unmittelbar nach Austreten aus einem der beiden Ausströmöffnungen ein Gasleitelement anströmt.The embodiment of the invention just described, which has two parallel flow channels, is characterized in that the flow resistance only has to be increased slightly. In particular, it can be avoided that one of the gas flows immediately after exiting one of the two outflow openings, a gas guide element.
Die
Ein großer Vorteil der hier beschriebenen Ausführungsformen ist, dass die Position des Ausströmbereichs im ersten Strömungskanal zu jedem Zeitpunkt der Expansion genau definiert ist.A great advantage of the embodiments described here is that the position of the outflow region in the first flow channel is precisely defined at each point in time of the expansion.
