Abstract
Description
Die Erfindung betrifft eine Vorhanggassack-Einheit nach dem Oberbegriff des Anspruchs 1.The The invention relates to a curtain airbag unit according to the preamble of claim 1.
Eine
Vorhanggassack-Einheit weist eine großflächige Gassackhülle und
einen Gasgenerator zur Befüllung
der Gassackhülle
auf. Die Gassackhülle
hat eine obere Kante, die im Bereich des Dachholms des Kraftfahrzeugs
befestigt ist, so dass sich die Längsrichtung des Gassacks entlang
der Fahrzeuglängsachse
erstreckt. Die Befüllung
muss von der oberen Kante her erfolgen. Es sind hierzu zwei Konzepte
bekannt:
Beim ersten Konzept befindet sich der Gasgenerator an
einem der beiden Enden der oberen Kante (zumeist dem hinteren) und
vom Gasgenerator erstreckt sich eine lange, dünne, mehrere Austrittsöffnungen aufweisende
Metalllanze ins Innere der Gassackhülle, welche das Gas über die
Länge der
Gassackhülle verteilt.A curtain airbag unit has a large-area airbag cover and a gas generator for filling the airbag cover. The airbag cover has an upper edge, which is fastened in the region of the roof rail of the motor vehicle, so that the longitudinal direction of the airbag extends along the vehicle longitudinal axis. The filling must be done from the upper edge. There are two known concepts for this:
In the first concept, the gas generator is located at one of the two ends of the upper edge (usually the rear) and from the gas generator, a long, thin, multi-outlet metal lance extends into the interior of the airbag shell, which distributes the gas over the length of the airbag shell.
In einem zweiten Konzept weist die Gassackhülle im Bereich der oberen Kante zwischen dem vorderen und dem hinteren Ende einen Aufnahmebereich für den Gasgenerator auf, welcher sich in das Innere der Gassackhülle hinein erstreckt oder zumindest mit dem Inneren verbunden ist. Hierzu kann der Aufnahmebereich beispielsweise L-förmig ausgebildet sein.In a second concept, the airbag cover in the upper edge between the front and the rear end a receiving area for the Gas generator, which is in the interior of the airbag cover extends or at least connected to the interior. For this purpose, the Recording area, for example, be L-shaped.
Es werden in der Regel zylindrische Gasgeneratoren eingesetzt, die aus Sicherheitsgründen schubneutral ausgebildet sind. Dies bedeutet, dass die Gasaustrittsöffnungen rotationssymmetrisch auf einem Teil der Mantelfläche des Gasgenerators angeordnet sind. Ohne zusätzliche Maßnahmen ergäbe sich hieraus das Problem, dass Gassackgewebe direkt von den heißen Ga sen angestrahlt und gegebenenfalls beschädigt würde. Es werden deshalb Deflektoren eingesetzt, die das Gassackgewebe vor dem ausströmenden Gas schützen.It As a rule, cylindrical gas generators are used, the safety-neutral for safety reasons are formed. This means that the gas outlet openings arranged rotationally symmetrically on a part of the lateral surface of the gas generator are. Without additional activities would result This causes the problem that gas bag fabric directly from the hot Ga sen illuminated and possibly damaged. There are therefore deflectors used, which protect the airbag fabric from the outflowing gas.
Aus der gattungsbildenden WO 02/079008 A1 ist ein solcher Deflektor bekannt, der in Form eines U-förmigen Metallbleches ausgeführt ist. Weiterhin ist aus dieser Druckschrift ein in die Gassackhülle eingenähtes Gasleitelement aus Gewebe bekannt.Out the generic type WO 02/079008 A1 is such a deflector known in the form of a U-shaped Metal sheet carried out is. Furthermore, from this document is a sewn into the airbag cover gas guide known from tissue.
Nachteilig an einem solchen Deflektorelement ist, dass sich die fertig montierte Gassackeinheit in einem Brandfall nicht schubneutral verhält. Im Falle eines Lagerbrandes verbrennt nämlich die aus Kunststoffgewebe bestehende Gassackhülle, der Gasgenerator und das mit dem Gasgenerator verbundenes Deflektorelement bleiben jedoch übrig. Um seinen Zweck, nämlich den Schutz des Gassackgewebes bei ausströmendem Gas erfüllen zu können, muss das Deflektorelement asymmetrisch aufgebaut sein. Hieraus folgt jedoch, dass sich die aus Gasgenerator und Deflektor bestehende Baugruppe nicht schubneutral verhält. Im Fall eines Lagerbrandes entsteht somit durch umherfliegende Gasgenerator-Deflektor-Baugruppen eine zusätzliche Gefahrenquelle.adversely on such a deflector element is that the fully assembled Airbag unit in a fire does not behave push-neutral. In the event of A camp fire burns the existing plastic fabric airbag cover, the gas generator and the However, with the gas generator connected deflector remain. To his Purpose, namely To meet the protection of the airbag fabric with outflowing gas can, must the deflector element be constructed asymmetrically. It follows however, that consists of the gas generator and deflector Module does not behave push-neutral. In the case of a camp fire arises thus by flying around gas generator-deflector assemblies a additional Hazard.
Hiervon ausgehend ist es Aufgabe der Erfindung, eine gattungsgemäße Vorhanggassack-Einheit dahingehend weiterzubilden, dass ihre Schubneutralität auch im Brandfall gewährleistet ist.Of these, Based on the object of the invention, a generic curtain gas bag unit to further develop that their thrust neutrality in the Fire is guaranteed is.
Diese Aufgabe wird durch eine Vorhanggassack-Einheit mit den Merkmalen des Anspruchs 1 gelöst.These Task is by a curtain airbag unit with the features of claim 1.
Das Deflektorelement der erfindungsgemäßen Gassackeinheit besteht – vorzugsweise vollständig – aus Gewebe und brennt deshalb im Brandfall gemeinsam mit der Gassackhülle ab, beziehungsweise verliert seine Festigkeit, so dass das Gas aus dem schubneutralen Gasgenerator direkt in die Umge bung entweichen kann. Das Deflektorelement ist, wie der Gasgenerator auch, zylinderförmig ausgebildet, wird aus einem flächigen Gewebezuschnitt zylinderförmig gefaltet und durch eine erste Verbindungsnaht zusammengehalten. Das Deflektorelement wird mit der Gassackhülle über eine Befestigungsnaht verbunden. Um eine über die Dauer des Gasaustritts hinreichende Widerstandsfähigkeit zu gewährleisten, ist das Deflektorelement zweilagig mit einer inneren und einer äußeren Lage ausgebildet. Hierbei deckt die innere Lage die erste Verbindungsnaht ab. Es hat sich nämlich herausgestellt, dass der kritische Bereich bei der Anströmung durch heißes Gas die Nähte sind.The Deflektorelement the gas bag unit according to the invention consists - preferably complete - made of fabric and therefore burns in the event of a fire together with the airbag cover, or loses its strength, so that the gas from the thrust-neutral gas generator can escape directly into the environment. The deflector element is, like the gas generator, cylindrical in shape, becomes from a plane Fabric cut cylindrical folded and held together by a first seam. The deflector element is connected to the gas bag envelope via a fastening seam. To one over the duration of the gas leakage sufficient resistance to ensure the Deflektorelement two-ply with an inner and an outer layer educated. Here, the inner layer covers the first seam from. It has become proved that the critical area during the flow through hot Gas the seams are.
