Abstract
Description
Die Erfindung betrifft ein Gassackmodul für einen Personenkraftwagen nach dem Oberbegriff des Anspruchs 1.The The invention relates to an airbag module for a passenger car according to the preamble of claim 1.
Bei
der Konzipierung eines Gassackmoduls tritt grundsätzlich das
Problem auf, dass die Anforderungen an das Gassackmodul in unterschiedlichen Unfallsituationen
sehr unterschiedlich sind. Besonders ausgeprägt ist dieses Problem bei Beifahrer-Gassackmodulen.
Hier können
die folgenden drei Extremsituationen auftreten:
Der zu schützende Beifahrer
sitzt angegurtet in seiner Standard-Sitzposition. Dies ist der Regel-
und Idealfall. Der Gassack sollte sich in dieser Situation schnell
entfalten, jedoch einen verhältnismäßig geringen
Innendruck aufweisen. Im zweiten wichtigen Fall sitzt der Beifahrer
in seiner Standard-Sitzposition,
ist jedoch nicht angegurtet. Auch hier sollte sich der Gassack schnell
entfalten, jedoch einen erhöhten Innendruck
aufweisen. Der dritte wesentliche Fall ist derjenige, in der der
Insasse – gegebenenfalls
ungegurtet – vornübergebeugt
auf dem Beifahrersitz sitzt. Hier besteht die Gefahr von Kopfverletzungen
durch den herausschießenden
Gassack. Besonders kritisch ist der Fall, bei dem es sich bei dem
vornüber gebeugten
Insassen um ein Kind von beispielsweise 6 Jahren handelt, da hier
insbesondere die Gefahr besteht, dass der Kopf des Insassen auf
einem Bereich des Armaturenbrettes aufliegt, der in der Nähe der Austrittsfläche des
Gassackes liegt.In the design of an airbag module, the fundamental problem arises that the requirements for the airbag module in different accident situations are very different. This problem is particularly pronounced in passenger gas bag modules. Here are the following three extreme situations:
The passenger to be protected sits belted in his standard seating position. This is the rule and ideal case. The gas bag should unfold quickly in this situation, but have a relatively low internal pressure. In the second important case, the passenger sits in his standard seating position, but is not belted. Again, the gas bag should unfold quickly, but have an increased internal pressure. The third essential case is the one in which the occupant, optionally unbegged, sits bent over in the passenger seat. There is a risk of head injuries caused by the escaping gas bag. Particularly critical is the case in which the front bent over occupant is a child, for example, 6 years, as there is a particular risk that the head of the occupant rests on an area of the dashboard, which is near the exit surface of the Airbag is located.
Es sind Ansätze bekannt, die hier entstehenden Probleme dadurch zu lösen, dass die Sitzposition des Insassen durch Sensoren detektiert und in Abhängigkeit hiervon das Verhalten des Gassackmoduls gesteuert wird. Insbesondere kann hierbei auf die effektive Leistung der Gasgeneratoreinheit Einfluss genommen werden. Solche aktiven Systeme sind jedoch aufwendig, teuer und vor allem störungsanfällig.It are approaches known to solve the problems arising here in that the seating position of the occupant detected by sensors and depending From this the behavior of the gas bag module is controlled. Especially this can affect the effective performance of the gas generator unit Be influenced. However, such active systems are expensive expensive and above all prone to failure.
Hiervon ausgehend ist es Aufgabe der Erfindung, ein passiv arbeitendes System zu schaffen, das den Schutz eines vornüber gebeugten Insassen, insbesondere eines vornüber gebeugten Kindes, verbessert, ohne den Schutz eines sich in Standard-Sitzposition befindenden Insassen zu verschlechtern.Of these, Based on the object of the invention, a passive working system to provide the protection of a bent over occupant, in particular one over bowed child, improved without the protection of a in standard sitting position worsening occupants.
Diese Aufgabe wird durch ein ein Gassackmodul mit den Merkmalen des Anspruchs 1 gelöst.These The object is achieved by a gas bag module having the features of the claim 1 solved.
Das erfindungsgemäße Gassackmodul weist ein Fangelement auf, das sich – vorzugsweise vom Gehäuse aus – durch den Gasraum des Gassacks zu einem Abschnitt der Gassackhülle erstreckt, der bei vollständig expandiertem Gassack einem oberen Bereich zugeordnet ist. Das Fangelement ist so dimensioniert, dass die Gassackhülle bei Vorhandensein des unversehrten Fangelements ihr maximales Endvolumen nicht erreichen kann. Das heißt, solange das Fangelement intakt ist, ist die Ausdehnung in im wesentlichen vertikaler Richtung der Gassackhülle durch das Fangelement begrenzt. Hierdurch wird in einer frühen Phase der Expansion die Gefahr einer Kopfverletzung bei einem vornüber gebeugten Insassen, insbesondere eines vornüber gebeugten Kindes, erheblich reduziert.The Gas bag module according to the invention has a catch element, which is - preferably from the housing - through extends the gas space of the gas bag to a portion of the gas bag envelope, the at full expanded gas bag is assigned to an upper area. The catch element is dimensioned so that the airbag cover in the presence of the intact Fangelements can not reach their maximum final volume. The is called, as long as the catching element is intact, the expansion is essentially in vertical direction of the airbag cover limits the catch element. This will be in an early stage the expansion the risk of a head injury in a bent forward Inmates, especially a bent over child, considerably reduced.
In einer späteren Expansionsphase kann das Fangelement funktionslos werden, und in einer bevorzugten Ausführungsform wird es dies auch, beispielsweise indem es reißt, so dass der Gassack sein Maximalvolumen erreichen kann und somit zum Auffangen eines sich in Standard-Sitzposition befindenden Insassen uneingeschränkt zur Verfügung steht.In a later one Expansion phase, the catching element can become inoperative, and in a preferred embodiment it also does so, for example by tearing it, so that the gas bag is its maximum volume can reach and thus catch one in standard seating position unrestricted occupants to disposal stands.
Weiter vorzugsweise hat das Fangelement weiterhin eine gasleitende Funktion und es unterteilt den Gassack in einen dem Insassen zugewandten Be reich und eine Art Wulst oder Blase zwischen dem Armaturenbrett und der Windschutzscheibe.Further Preferably, the catch element further has a gas-conducting function and it subdivides the gas bag into a region facing the occupant and a kind of bead or bubble between the dashboard and the Windshield.
Weiter vorzugsweise weist das Fangelement zwei Seitenflächen mit je einer Ausnehmung auf. Hierdurch kann eine gasleitende Funktion sichergestellt werden, die eine zu starke Belastung des Kopfes des Insassen verhindert.Further Preferably, the catch element has two side surfaces, each with a recess on. As a result, a gas-conducting function can be ensured which prevents too much stress on the occupant's head.
