Abstract

Airbags for protecting vehicle occupants are generally filled by a gas generator which operates on a pyrotechnical basis. The outlet openings of such airbags are therefore subjected to the risk of being burnt by the hot, outflowing gases. This risk is to be eliminated according to the invention by virtue of the fact that a patch is attached to the inside of the airbag, which patch has an opening which is concentric with respect to the outlet opening and has a smaller diameter than it and in that the patch is composed of a resilient material.

Description

Gaskissen zum Schutz der Insassen von Fahrzeugen,Gas cushions to protect vehicle occupants,

insbesondere von Kraftwagen" Die Erfindung betrifft ein Gaskissen zum Schutz der Insassen von Fahrzeugen, insbesondere von Kraftwagen, das im Falle eines Unfalls durch einen Gaserzeuger aufblasbar ist und das mindestens eine Abströmöffnung für das Gas aufweist, wobei an dem Gaskissen ein die Abströmöffnung überdeckender Flecken befestigt ist. in particular of motor vehicles "The invention relates to a gas cushion to protect the occupants of vehicles, especially motor vehicles, in the event of an accident is inflatable by a gas generator and the at least one discharge opening for the gas, wherein on the gas cushion a covering the outflow opening Patch is attached.

Eine derartige Sicherheitseinrichtung ist bereits der DE-PS 16 80 034 als bekannt zu entnehmen. Der dort verwendete Flecken verschließt im Ausgangszustand die Austrittsbffnung vollständig und dient als Sollbruchstelle, die bei einem vorbestimmten Druck im Gaskissen aufreißt und das Abstromen des Gases ermöglicht.Such a safety device is already DE-PS 16 80 034 as known. The stain used there closes in its initial state the outlet opening completely and serves as a predetermined breaking point, which at a predetermined The pressure in the gas cushion ruptures and the gas can flow away.

Das zum Füllen des Gaskissens dienende Gas wird im allgemeinen durch Abbrennen eines pyrotechnischen Treibsatzes erzeugt, so daß das Gas eine relativ hohe Temperatur aufweist. Das hat die Gefahr zur Folge, daß die Randbereiche der Abströmöffnungen durch das austretende Gas verbrennen, was zu einem Einreißen des Materials führen kann, wodurch das Gaskissen schlagartig drucklos wird und damit seine Aufgabe nicht erfüllen kann.The gas used to fill the gas bag is generally through Burning off a pyrotechnic propellant generated so that the Gas has a relatively high temperature. This has the consequence that the The edge areas of the outflow openings are burned by the escaping gas, which leads to a The material can tear, causing the gas cushion to suddenly become depressurized and therefore cannot do its job.

Der vorliegenden Erfindung lag daher die Aufgabe zugrunde, ein Gaskissen der eingangs definierten Gattung so weiterzubilden, daß ein wirksamer Schutz der gefährdeten Randbereiche der Abströmöffnungen sichergestellt ist.The present invention was therefore based on the object of a gas cushion of the genus defined at the beginning so that an effective protection of the endangered edge areas of the outflow openings is ensured.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß der Flecken auf der Innenseite des Gaskissens befestigt ist und eine zur Abströmöffnung konzentrische Öffnung kleineren Durchmessers aufweist, und daß der Flecken aus einem nachgiebigen Material besteht.This object is achieved according to the invention in that the stain is attached to the inside of the gas cushion and one concentric to the discharge opening Has a smaller diameter opening, and that the patch is made of a flexible Material.

Dadurch wird erreicht, daß sich das Material des Fleckens schützend an die Wandbereiche der Abströmöffnung anlegt und diese gegenüber dem heißen Gas abdeckt.This ensures that the material of the stain is protective applied to the wall areas of the discharge opening and this against the hot gas covers.

Der Gegenstand der Erfindung soll im folgenden anhand eines in der Zeichnung dargestellten Ausführungsbeispiels näher erläutert werden.The object of the invention is to be based on one in the Drawing illustrated embodiment will be explained in more detail.

In der Zeichnung zeigen Fig. 1 schematisch eine Seitenansicht eines Teils eines Personenkraftwagens mit am Lenkrad angeordnetem Gaskissen zum Schutz des Fahrers, Fig. 2 in größerem Maßstab einen Schnitt nach der Linie II - II in Fig. 1, im Ausgangszustand, und Fig. 3 eine Darstellung entsprechend Fig. 2, jedoch bei abströmendem Gas.In the drawing, Fig. 1 shows schematically a side view of a Part of a passenger car with a gas cushion on the steering wheel for protection of the driver, Fig. 2 on a larger scale a section along the line II - II in Fig. 1, in the initial state, and Fig. 3 shows a representation accordingly Fig. 2, but with outflowing gas.

Am Lenkhandrad 1 eines schematisch angedeuteten Kraftwagens 2 ist ein dem Schutz des Fahrers dienendes Gaskissen 3 angeordnet, das in nicht dargestellter Weise über eine Gaserzeugereinheit befüllbar ist.On the steering wheel 1 of a schematically indicated motor vehicle 2 is a gas cushion 3 serving to protect the driver is arranged, which is not shown in FIG Way can be filled via a gas generator unit.

Wie in den Fig. 2 und 3 näher dargestellt, weist das Gaskissen 3 eine Abströmöffnung 4 auf. Im Bereich dieser Abströmöffnung 4 ist auf die Innenseite des Gaskissens 3 ein Flecken 5 aufgesetzt und durch Kleben, Nähen od. dgl. befestigt. Dieser Flecken 5 weist eine zur Abströmöffnung 4 konzentrische, jedoch kleinere Öffnung 6 auf - Fig. 2 -, die bei entsprechender Materialwahl durch das unter hohem Druck austretende Gas in der in Fig. 3 der Zeichnung dargestellten Weise aufgeweitet und verformt wird. Dadurch bildet der Flecken 5 einen Schutz für die Abströmöffnung 4.As shown in more detail in FIGS. 2 and 3, the gas cushion 3 has a Outlet opening 4. In the area of this discharge opening 4 is on the inside of the gas cushion 3 a patch 5 placed and od by gluing, sewing. The like. Fastened. This patch 5 has a concentric to the outflow opening 4, but smaller Opening 6 on - Fig. 2 -, with the appropriate choice of material by the under high Pressure escaping gas expanded in the manner shown in Fig. 3 of the drawing and is deformed. As a result, the patch 5 forms a protection for the discharge opening 4th
