Description
Die vorliegende Erfindung betrifft einen Airbag und insbesondere einen Airbag, der angepasst ist, um Schutz für den Insassen eines Kraftfahrzeuges zu bieten. Viele Airbags sind derart konstruiert, dass sie eine darin ausgebildete Öffnung aufweisen, die einen Teil eines Gasgenerators aufnimmt, so dass ein Teil des Gehäuses des Gasgenerators innerhalb des Airbags angeordnet ist und ein anderer Teil seines Gehäuses sich vom Airbag erstreckt, um das Befestigen des Airbags zu erleichtern. Beim Aufblasen des Airbags tritt Gas aus jenem Teil des Airbag-Gehäuses aus, welcher innerhalb des Airbags angeordnet ist. Während einige Gasgeneratoren komprimiertes Gas freisetzen und somit ein kaltes Gas erzeugen, erzeugen andere Gasgeneratoren, welche von pyrotechnischer Natur sind, ein sehr heißes Gas, und andere Gasgeneratoren, welche so genannte Hybrid-Gasgeneratoren sind, erzeugen Gas bei einer Zwischentemperatur.The The present invention relates to an airbag, and more particularly to an airbag Airbag adapted to provide protection to the occupant of a motor vehicle to offer. Many airbags are designed to be one formed therein opening comprising a part of a gas generator, so that a part of the housing the gas generator is disposed within the airbag and another part his case extends from the airbag to facilitate attachment of the airbag. When inflating the airbag gas escapes from that part of the airbag housing, which is arranged inside the airbag. While some gas generators are compressed Release gas and thus produce a cold gas, others generate Gas generators, which are of pyrotechnic nature, a very hot Gas, and other gas generators, called hybrid gas generators are generate gas at an intermediate temperature.
Der Gasfluss, zumindest während der Anfangsphasen des Aufblasens des Airbags, kann sehr aggressiv sein, und daher muss die Region des Airbags, welche den Gasgenerator unmittelbar umgibt und welche als „Hals"-Region bezeichnet werden kann, in der Lage sein, dem Gasfluss zu widerstehen, ohne beeinträchtigt zu werden. Um das Risiko eines am Gewebe des Airbags entstehenden Schadens zu minimieren, wurde vorgeschlagen, eine zusätzliche Schicht an Gewebe in der Halsregion vorzusehen, die als Wärmeschutzschicht dient, insbesondere bei Verwendung eines pyrotechnischen Gasgenerators oder eines Hybrid-Gasgenerators. Diese Schicht kann an das Hauptgewebe des Airbags angeleimt oder angenäht oder mit Hilfe von Stiftbolzen, die auf dem Gasgenerator bereitgestellt sind, in Position befestigt werden. Alternativ dazu kann das Gewebe des Airbags mit einer Beschichtung versehen werden, welche aus Silikon oder einem anderen ähnlichen Material gebildet ist.Of the Gas flow, at least during the initial stages of inflation of the airbag, can be very aggressive be, and therefore the region of the airbag, which the gas generator immediately surrounding and which can be referred to as "neck" region, in the Be able to withstand the flow of gas without being impaired become. To reduce the risk of damage to the fabric of the airbag To minimize this, it was suggested to place an additional layer of tissue in provide the neck region, which serves as a heat shield layer, in particular when using a pyrotechnic gas generator or a hybrid gas generator. This layer can be glued to the main fabric of the airbag or sewn or with the help of stud bolts provided on the gas generator are to be fixed in position. Alternatively, the tissue of the airbag are provided with a coating made of silicone or another similar material is formed.
Es ist unpraktisch, viele verschiedene Versionen einer Wärmeschutzschicht zu verwenden, und die vorliegende Erfindung möchte einen verbesserten Airbag bereitstellen.It is impractical, many different versions of a thermal insulation layer to use, and the present invention seeks an improved airbag provide.
Gemäß der vorliegenden Erfindung wird ein Airbag bereitgestellt, wobei der Airbag mit einer Öffnung versehen ist, welche angepasst ist, um einen Gasgenerator aufzunehmen, wobei die Öffnung von einer Halsregion umgeben ist, wobei die Halsregion mit einer Verstärkung versehen ist, wobei die Verstärkung zwei Gewebeschichten aufweist, welche mehrere im Wesentlichen hermetisch abgedichtete Zellen bilden.According to the present According to the invention, an airbag is provided, wherein the airbag is provided with an opening which is adapted to receive a gas generator, wherein the opening is surrounded by a neck region, wherein the neck region with a reinforcement is provided, the reinforcement has two tissue layers, which are several substantially hermetic forming sealed cells.
Vorzugsweise ist die Verstärkung ein getrenntes Verstärkungselement, welches zusätzlich zum Gewebe des Airbags vorhanden ist.Preferably is the reinforcement a separate reinforcing element, which in addition to Fabric of the airbag is present.
Praktischerweise wird die Verstärkung unter Verwendung einer Einstück-Webtechnik ausgebildet.conveniently, becomes the reinforcement using a one-piece weaving technique educated.
Vorzugsweise ist mindestens die Verstärkung mit einer Silikonbeschichtung versehen.Preferably is at least the reinforcement provided with a silicone coating.
Vorteilhafterweise ist die Verstärkung in 470-Dtex-Garn gewebt.advantageously, is the reinforcement Woven in 470 Dtex yarn.
Alternativ dazu ist die Verstärkung in 350-235-Dtex-Garn gewebt.alternative this is the reinforcement woven in 350-235 dtex yarn.
Zum besseren Verständnis der Erfindung und damit weitere Merkmale der Erfindung geschätzt werden können, wird die Erfindung nun beispielhaft unter Bezugnahme auf die beiliegenden Zeichnungen beschrieben. Es zeigen:To the better understanding the invention and thus other features of the invention are appreciated can, The invention will now be described by way of example with reference to the accompanying drawings Drawings described.
