Abstract

The airbag has a gas generator (5) that generates a fuel gas, which is filled in the airbag through fuel gas filling-in openings (3) and an underlying pivotal point (2). The airbag is unfolded in a fan-shaped manner when filling the gas, where the airbag is fastened in a backrest (4) of a motor vehicle seat and consisting of two connected chambers. A fuel gas venting hole is provided for emptying the airbag.

Description

Das Gebrauchsmuster betrifft einen Seitenairbag wie sie beispielsweise in den Druckschriften DE 196 46 698 A1 , DE 197 14 267 A1 , DE 197 30 148 A1 , DE 197 42 151 A1 , DE 197 42 584 A1 , DE 197 46 387 A1 , DE 197 51 898 A1 , DE 198 14 054 A1 , DE 100 20 920 A1 , DE 102 46 769 A1 , DE 103 03 901 A1 ,... beschrieben sind. Ihnen allen ist gemein, dass sie seitlich in die Rückenlehne eines Kraftfahrzeugsitzes eingebaut sind und dass sich der Gassack beim Befüllen mit Treibgas schlagartig nach vorne entfaltet.The utility model relates to a side airbag as shown for example in the publications DE 196 46 698 A1 . DE 197 14 267 A1 . DE 197 30 148 A1 . DE 197 42 151 A1 . DE 197 42 584 A1 . DE 197 46 387 A1 . DE 197 51 898 A1 . DE 198 14 054 A1 . DE 100 20 920 A1 . DE 102 46 769 A1 . DE 103 03 901 A1 , ... are described. They all have in common that they are installed laterally in the backrest of a motor vehicle seat and that the gas bag unfolds when filling with propellant gas suddenly forward.

Es kommt immer wieder vor, dass Airbags in Kraftfahrzeugen durch das unbeabsichtigte Aktivieren des Gasgenerators aufgeblasen werden ohne dass sich ein Unfall ereignet hat. Derartige Fehlzündungen haben oftmals fatale Folgen, wenn beispielsweise der Arm des Fahrers durch den sich schlagartig nach vorne öffnenden Seitenairbag beeinflusst und nach vorne geschleudert wird. Durch die plötzliche und unerwartete stoßartige Bewegung des Armes kann der Fahrer das Lenkrad verreißen und möglicher weise einen Unfall verursachen, oder die Hand des Fahrers kann am Armaturenbrett oder der Windschutzscheibe aufprallen wodurch Verletzungen entstehen können.It happens again and again that airbags in motor vehicles by the unintentional activation of the inflator be inflated without an accident having occurred. Such misfires Often have fatal consequences when, for example, the arm of the driver influenced by the sudden opening to the front side airbag and is thrown forward. By the sudden and unexpected jerky Movement of the arm allows the driver to pull the steering wheel and possibly more cause an accident or the driver's hand may Dashboard or the windshield bounce causing injury can.

Dem Gebrauchsmuster liegt daher die Aufgabe zugrunde einen Seitenairbag anzugeben durch den im Falle eines Crash oder einer Fehlzündung zuverlässig verhindert wird, dass beim Befüllen des Gassackes mittels einer Treibgasquelle der Arm des Fahrers nach vorne geschleudert wird, sondern dass der Arm des Fahrers durch den Gassack von der Armauflage weg zum Oberkörper hin abgedrängt wird.the Utility model is therefore the object of a side airbag to be reliably prevented by the case of a crash or a misfire will that when filling of the airbag by means of a propellant gas source of the driver's arm is thrown forward, but that the driver's arm through the gas bag is pushed away from the armrest to the upper body.

Diese Aufgabe wird durch den Anspruch 1 gekennzeichneten Seitenairbag gelöst; vorteilhafte Weiterbildungen und Ausgestaltungen sind in den Unteransprüchen angegeben.These Task is characterized by the claim 1 side airbag solved; advantageous developments and refinements are specified in the subclaims.

Der Grundgedanke des Gebrauchsmusters besteht darin, einen aus mehreren zusammenhängenden Kammern bestehenden Gassack zu fertigen der sich beim Befüllen mit Treibgas über entsprechende Treibgaseinfüllöffnungen und einem untenliegenden Drehpunkt fächerförmig entfaltet, wodurch der Arm des Fahrers von der Armauflage weg zum Oberkörper hin abgedrängt wird.Of the The basic idea of the utility model is to use one of several related Chambers existing gas bag to be manufactured when filling with Propellant over corresponding Treibgaseinfüllöffnungen and unfolds a fan-shaped underlying pivot point, whereby the Arm of the driver is pushed away from the armrest to the upper body.

Bei einem Crash mit Seitenaufprall, wo der Seitenairbag gezielt aktiviert wird, bietet die fächerförmige Entfaltung der einzelnen Kammern des Gassackes der Vorteil, dass in kürzester Zeit, der Oberarm und das Schultergelenk des Fahrers geschützt wird, weil für das Befüllen der ersten Kammer, beispielsweise bei einem aus drei Kammern bestehenden Gassack, einschließlich Zündung und Aufsprengen der Abdeckung höchstens die halbe Zeit der Gesamtbefüllzeit benötigt wird.at a crash with side impact, where the side airbag activated specifically will provide the fan-shaped unfolding the individual chambers of the airbag the advantage that in the shortest possible Time, the upper arm and the shoulder joint of the driver is protected, because for the filling the first chamber, for example in one of three chambers Airbag, including ignition and blowing open the cover at most half the time of the total filling time needed becomes.

In einem besonderen Ausführungsbeispiel können die Treibgaseinfüllöffnungen zwischen den einzelnen Kammern als Reißnähte ausgebildet sein. Dadurch bleibt der aufgebaute Innendruck in den bereits befüllten Kammern nahezu erhalten.In In a particular embodiment, the Treibgaseinfüllöffnungen be formed between the individual chambers as tear seams. Thereby the built-up internal pressure remains in the already filled chambers almost preserved.

Das erfindungsgemäße Prinzip wird nachfolgend anhand der Zeichnungen näher erläutert.The inventive principle will be explained in more detail with reference to the drawings.

1 zeigt einen beispielsweise aus drei Kammern bestehenden Seitenairbag 1 der seitlich in der Rückenlehne 4 des Fahrzeugsitzes befestigt und mit Treibgas aus dem Gasgenerator 5 über die Treibgaseinfüllöffnungen 3 befüllt ist. 1 shows a side airbag, for example, consisting of three chambers 1 the side in the backrest 4 attached to the vehicle seat and with propellant gas from the gas generator 5 over the Treibgaseinfüllöffnungen 3 is filled.

Wie durch den Pfeil verdeutlicht, hat sich der Gassack 1 über den Drehpunkt 2 fächerförmig entfaltet.As illustrated by the arrow, the gas bag has 1 over the pivot point 2 unfolded fan-shaped.

2 zeigt den Fahrer während der Fahrt. Der Arm 6 des Fahrers liegt auf der Armauflage 7 an der Tür 8. 2 shows the driver while driving. The arm 6 the driver lies on the armrest 7 at the door 8th ,

3 zeigt den mit Treibgas befüllten Gassack 1 und den Arm des Fahrers der von der Armauflage 7 weg zum Oberkörper hin abgedrängt wurde. 3 shows the filled with propellant gas bag 1 and the arm of the driver of the armrest 7 was pushed away to the upper body.
