Abstract

An airbag for protecting the occupant of a vehicle from collision against a side wall of the vehicle is stowed in a folded fashion to the side of the occupant and is situated, when it has been filled, in the form of an elongated balloon between the occupant and the side wall, the airbag having a projecting continuation which runs in the direction of the head and neck region of the occupant and supports the head in good time when the body collides.

Description

Die Erfindung betrifft einen Gassack gemäß dem Oberbegriff des Anspruchs 1.The invention relates to an airbag according to the preamble of Claim 1.

Aus der DE-A 42 23 620 ist ein Gassack bekannt, der durch einströmendes Gas nach seiner Entfaltung zwischen einem Fahrzeuginsassen und einer Fahrzeugseitenwand liegt. Der Gassack bildet dabei die übliche Form eines Ballons. Da der Insasse bei einem Anprall eines anderen Fahrzeugs an die Fahrzeugseite gegen die Seitenwand geschleudert werden kann, ist der seitliche Gassack dazu geeignet, dem Insassen Verletzungen durch den Anprall an die Innenverkleidung der Seitenwand zu ersparen. Dabei wurde aber nicht berücksichtigt, daß der Kopf des Insassen einen größeren Abstand zur Seitenwand einnimmt und deshalb trotz des Abfangens des Insassenkörpers weiter gegen die Seitenwand beschleunigt wird. Hierbei kann es zu starker Belastung der Halswirbelsäule kommen.From DE-A 42 23 620 an airbag is known which by inflowing gas after its release between one Vehicle occupants and a vehicle side wall lies. The gas bag forms the usual shape of a balloon. Because the occupant at an impact of another vehicle on the vehicle side the side wall can be flung is the side one Airbag is suitable for injuries caused by the occupant To avoid impact on the inner lining of the side wall. However, it was not considered that the head of the occupant takes a greater distance from the side wall and therefore despite catching the occupant body further against the side wall is accelerated. This can lead to excessive stress on the Cervical spine come.

Zum allgemeinen Hintergrund wird noch auf folgende Druckschriften verwiesen: DE-A 40 18 470, EP-A 0 529 389 und DE-C 39 21 289.The general background is as follows References: DE-A 40 18 470, EP-A 0 529 389 and DE-C 39 21 289.

Die Aufgabe der Erfindung besteht darin, einen Fahrzeuginsassen bei einem Seitenaufprall durch einen seitlichen Gassack sicher abzustützen.The object of the invention is a vehicle occupant in the event of a side impact through a side gas bag to support.

Die Aufgabe wird durch die kennzeichnenden Merkmale des Patentanspruchs 1 gelöst. The task is characterized by the characteristic features of the Claim 1 solved.  

Die der seitlichen Körperform besser angepaßte Ausbildung des seitlichen Gassacks stützt den Kopf des Insassen bei einem seitlichen Anprall ebenso wie den Körper ab und vermindert dadurch die Belastung der Halswirbelsäule. Der sich an der Seitenwand abstützende Gassack muß für diese Wirkung im Kopfbereich des Insassen in Richtung des Fahrzeuginnenraums vergrößert werden, wobei keine gravierende Erhöhung der Befülleistung eines Gasgenerators notwendig wird, welcher wiederum mehr Gewicht verursachen und Bauraum benötigen würde. Getrennte Gassäcke für Kopf und Körperbereich erhöhen die Kosten aufgrund der Teilevielfalt wie auch der umfangreicheren Steuerung des Entfaltungsvorgangs. Die notwendige Form des Gassacks ist einerseits durch einen entsprechenden Zuschnitt des Gassackgewebes wie auch durch eine auf diese Form abgestimmte Fangbandanordnung im Gassack zu erreichen.The training of the body shape better adapted to the side side airbags supports the head of the occupant in one lateral impact as well as the body decreases and decreases thereby the strain on the cervical spine. The one at the For this effect, the side wall-supporting gas bag must be in Head area of the occupant in the direction of the vehicle interior be enlarged, with no serious increase in Filling performance of a gas generator is necessary, which would in turn cause more weight and would require space. Separate gas bags for the head and body area increase the costs due to the variety of parts as well as the more extensive ones Control of the deployment process. The necessary form of Gas bags is on the one hand through a corresponding cut of the Airbag fabric as well as a matched to this shape To reach the tether arrangement in the gas bag.

Weitere Vorteile und Ausgestaltungen gehen aus den Unteransprüchen und der Beschreibung hervor.Further advantages and configurations come from the Subclaims and the description.

Die Erfindung ist nachstehend anhand einer Zeichnung näher beschrieben.The invention is described below with reference to a drawing described.

Die Figur zeigt einen Fahrzeuginsassen 1 auf einem Sitz 2 in einem nicht weiter dargestellten Fahrzeuginnenraum, der z. B. durch einen Aufprall eines anderen Fahrzeugs auf eine Fahrzeugseite gegen eine Fahrzeugseitenwand 3 geschleudert wird. Durch diesen Fahrzeugcrash wurde ein seitlicher Gassack 4 ausgelöst, der in der Seitenwand 3 (oder Fahrzeugtür) eingefaltet lag und durch seine Befüllung mit Gas nun als länglicher Ballon zwischen dem Insassen 1 und der Seitenwand 3 liegt, wodurch der Insasse 1 vor einem harten Anprall an die Seitenwand 3 geschützt wird. Dabei weist der Gassack 4 einen in Richtung des Kopf- und Halsbereichs des Insassen 1 abkragenden Fortsatz 5 auf, welcher bei dieser Insassenbewegung den Kopf 6 rechtzeitig abstützt und dadurch verhindert, daß die Halswirbelsäule durch eine starke Kopfneigung oder -verdrehung in Mitleidenschaft gezogen wird. Dabei stützt sich der Gassack 4 mit seiner speziell der Seitenwand angepaßten Form an der Seitenwand 3 ab. Die Form des Gassacks 4 kann durch im Sackinneren Wände des Gassacks verbindende, in diesem Sinne bekannte Fangbänder erzielt oder auch bereits im Zuschnitt der Gassackhülle vorgegeben werden.The figure shows a vehicle occupant 1 on a seat 2 in a vehicle interior, not shown, which z. B. is thrown by a collision of another vehicle on a vehicle side against a vehicle side wall 3 . This vehicle crash triggered a side airbag 4 , which was folded in the side wall 3 (or vehicle door) and, due to its filling with gas, now lies as an elongated balloon between the occupant 1 and the side wall 3 , as a result of which the occupant 1 faces a hard impact the side wall 3 is protected. The airbag 4 has an extension 5 projecting in the direction of the head and neck area of the occupant 1 , which supports the head 6 in good time during this occupant movement and thereby prevents the cervical spine from being affected by a strong head tilt or twist. The airbag 4 is supported on the side wall 3 with its shape specially adapted to the side wall. The shape of the gas bag 4 can be achieved by means of tether straps connecting the inside of the gas bag, which are known in this sense, or can already be predetermined in the cutting of the gas bag envelope.
