Seitenairbaq für ein Insassenrückhaltesvstem in einem KraftfahrzeugSide airbaq for an occupant restraint system in a motor vehicle

Beschreibungdescription

Die Erfindung 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 invention relates to a side airbag as described 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 DE 10 898 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 unfolds the gas bag when filling with propellant gas suddenly forward.

Weiterhin ist aus der EP 0818366 A1 ein in der Rückenlehne eines Kraftfahrzeuges eingebauter Seitenairbag bekannt. Der Seitenairbag besteht aus einem durchgehenden Innenraum, der an 2 Stellen durch Taschen ausgeformt ist. Die Entfaltungsrichtung des Airbags beim Befüllen mit Treibgas erfolgt geradlinig von der Sitzlehne schlagartig nach vorne.Furthermore, EP 0818366 A1 discloses a side airbag installed in the backrest of a motor vehicle. The side airbag consists of a continuous interior, which is formed in two places by pockets. The deployment direction of the airbag when filling with propellant takes place straight from the seat back abruptly 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 jDeeinflusst 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. Der Erfindung 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.It happens again and again that airbags in motor vehicles are inflated by the unintentional activation of the gas generator without an accident has occurred. Such misfires often have fatal consequences if, for example, the driver's arm is deflected and thrown forwards by the side opening airbag which suddenly opens to the front. The sudden and unexpected jerking movement of the arm may cause the driver to tear the steering wheel and possibly cause an accident, or the driver's hand may bounce on the dashboard or windshield, causing injury. The invention is therefore based on the object to provide a side airbag is reliably prevented in the event of a crash or a misfire that when filling the airbag by means of a propellant gas source of the driver's arm is thrown forward, but that the arm of the driver through the airbag of the armrest is pushed away to the upper body.

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

Der Grundgedanke der Erfindung besteht darin, einen aus mehreren zusammenhängenden keilförmigen 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.The basic idea of the invention is to manufacture a gas bag consisting of several contiguous wedge-shaped chambers which unfolds in a fan-shaped manner when being filled with propellant gas via corresponding propellant gas filling openings and an underlying pivot point, whereby the driver's arm is pushed away from the armrest towards the upper body.

Durch die fächerförmige Entfaltung des in der Rückenlehne befestigten Gassackes ergibt sich eine von außen zum untenliegenden Drehpunkt hin führende keilförmige Form der einzelnen Kammern und einen bogenförmigen Bewegungsablauf von oben nach unten.Due to the fan-shaped development of the airbag secured in the backrest results in a wedge-shaped form of the individual chambers leading from the outside to the bottom pivot point and a curved movement from top to bottom.

Die Zwischenwände die jeweils mindestens eine Treibgaseinfüllöffnung enthalten werden durch die keilförmigen Kammern gebildet.The intermediate walls which each contain at least one Treibgaseinfüllöffnung are formed by the wedge-shaped chambers.

Die einzelnen keilförmigen Kammern sind beispielsweise durch Nähte miteinander verbunden.The individual wedge-shaped chambers are connected to each other for example by seams.

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 keilförmigen Kammer, beispielsweise bei einem aus drei Kammern bestehenden Gassack, einschließlich Zündung und Aufsprengen der Abdeckung höchstens die halbe Zeit der Gesamtbefüllzeit benötigt wird. In einem weiteren Ausführungsbeispiel können die Treibgaseinfüllöffnungen zwischen den einzelnen keilförmigen Kammern als Reißnähte ausgebildet sein. Dadurch bleibt der aufgebaute Innendruck in den bereits befüllten Kammern nahezu erhalten.In a crash with side impact, where the side airbag is selectively activated, the fan-shaped deployment of the individual chambers of the airbag offers the advantage that in a very short time, the upper arm and the shoulder joint of the driver is protected, because for filling the first wedge-shaped chamber, for example in the case of a three-chamber gas bag, including ignition and blowing open the cover, at most half the time of the total filling time is required. In a further embodiment, the Treibgaseinfüllöffnungen between the individual wedge-shaped chambers may be formed as tear seams. As a result, the built-up internal pressure in the already filled chambers is almost preserved.

In einem besonders kostengünstigen Ausführungsbeispiel besteht der Gassack aus einem Kissen mit mindestens zwei keilförmigen Kammern. Die Außenform des Kissens und die keilförmigen Kammern sind beispielsweise durch Nähte hergestellt. Die Treibgaseinfüllöffnungen werden durch Unterbrechungen der Nähte erzeugt.In a particularly cost-effective embodiment of the gas bag consists of a cushion with at least two wedge-shaped chambers. The outer shape of the pad and the wedge-shaped chambers are made for example by seams. The Treibgaseinfüllöffnungen are generated by interruptions of the seams.

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

Fig. 1 zeigt einen beispielsweise aus drei keilförmigen Kammern 9 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. Wie durch den Pfeil verdeutlicht, hat sich der Gassack 1 über den Drehpunkt 2 fächerförmig entfaltet.Fig. 1 shows an existing example of three wedge-shaped chambers 9 side airbag 1 which is mounted laterally in the backrest 4 of the vehicle seat and filled with propellant gas from the gas generator 5 via the Treibgaseinfüllöffnungen 3. As illustrated by the arrow, the gas bag 1 has unfolded fan-shaped over the pivot point 2.

Fig. 2 zeigt den Fahrer während der Fahrt. Der Arm 6 des Fahrers liegt auf der Armauflage 7 an der Tür 8.Fig. 2 shows the driver while driving. The driver's arm 6 rests on the armrest 7 on the door 8.

Fig. 3 zeigt den mit Treibgas befüllten Gassack 1 und den Arm 6 des Fahrers der von der Armauflage 7 weg zum Oberkörper hin abgedrängt wurde. Fig. 3 shows the filled with propellant gas bag 1 and the arm 6 of the driver who was pushed away from the armrest 7 to the upper body.
