Abstract
Die Erfindung betrifft einen Gassack bzw. Airbag mit dessen Ausdehnung begrenzenden Fangbändern (2, 3), wobei die Länge eines ersten Fangbandes (2) mittels einer ihrerseits durch die Zugspannung eines weiteren Fangbandes oder den Gasdruck im Airbag gesteuerten Sperr- bzw. Hemmvorrichtung steuerbar ist.The invention relates to a gas bag or airbag with the expansion limiting tethers (2, 3), wherein the length of a first tether (2) by means of a turn by the tension of another tether or the gas pressure in the airbag controlled blocking or inhibiting device is controllable ,
Description
Die Erfindung bezieht sich auf einen Gassack bzw. Airbag mit dessen Ausdehnung begrenzenden Fangbändern.The The invention relates to an airbag or airbag with its Extension limiting tethers.
Ein
derartiger Airbag ist Gegenstand der
Deshalb ist es grundsätzlich bekannt, Fahrzeugsitze mit Sitzbelegungssensoren auszurüsten, die die Installation eines Kindersitzes erkennen und den Gasgenerator ausgeschaltet halten, so dass der Airbag bei einem Unfall nicht wirksam wird und das im Kindersitz platzierte Kind nicht verletzen kann.Therefore it is basically known to equip vehicle seats with seat occupancy sensors, the recognize the installation of a child seat and the gas generator Keep it off so that the airbag does not crash in an accident becomes effective and does not injure the child placed in the child safety seat can.
Bislang wurde noch keine Möglichkeit gefunden, den vergleichsweise teuren Sitzbelegungssensor zu erübrigen und gleichwohl die Sicherheit eines Kindes in einem Kindersitz zu gewährleisten.So far was still no way found to spare the comparatively expensive seat occupancy sensor and nevertheless to ensure the safety of a child in a child seat.

Aufgabe der Erfindung ist es nun, einen Airbag zu schaffen, der auch dann gefahrlos aufgeblasen werden kann, wenn auf dem zugeordneten Fahrzeugsitz ein Kindersitz angeordnet ist.task The invention is now to provide an airbag, even then can be safely inflated when on the assigned vehicle seat a child seat is arranged.
Diese Aufgabe wird bei einem Airbag der eingangs angegebenen Art erfindungsgemäß dadurch gelöst, dass die Länge oder Auszugsgeschwindigkeit eines ersten Fangbandes mittels einer ihrerseits durch die Zugspannung eines weiteren Fangbandes oder den Gasdruck im Airbag gesteuerten Sperr- bzw. Hemmvorrichtung steuerbar ist. Die Erfindung beruht auf dem allgemeinen Gedanken, das Maß der Ausbreitung bzw. Ausbreitungsgeschwindigkeit des Airbags in einer kritischen Richtung in Abhängigkeit von dem Gasdruck im Airbag bzw. in Abhängigkeit von der Zugspannung zu steuern, die ein die Ausbreitung des Airbags in einer unkritischen Richtung begrenzendes weiteres Fangband aufgrund des Gasdruckes innerhalb des Airbags erleidet. Im Ergebnis lässt sich damit gewährleisten, dass sich der Airbag in der unkritischen Richtung ungehindert ausdehnt, während das Airbagvolumen in der kritischen Richtung nur vergleichsweise langsam oder stufenweise anwächst. Damit kann ein unzulässig harter Schlag des Airbags gegen das auf dem Kindersitz sitzende Kind sicher vermieden werden.These The object is achieved according to the invention in an airbag of the type specified, that the length or extraction speed of a first tether by means of a in turn, by the tension of another tether or the gas pressure controlled in the airbag locking or inhibiting device controllable is. The invention is based on the general idea, the degree of propagation or Propagation speed of the airbag in a critical Direction depending on the gas pressure in the airbag or depending on the tension to control the one the spread of the airbag in a non-critical Direction limiting further tether due to the gas pressure inside the airbag suffers. As a result, it can be guaranteed that the airbag expands unhindered in the uncritical direction, while the Airbag volume in the critical direction only comparatively slowly or gradually increases. This can be inadmissible hard blow of the airbag against the child sitting on the child seat safely avoided.
Gemäß einer bevorzugten Ausführungsform ist vorgesehen, dass die Ausdehnung des Airbags vom ersten Fangband in der gefährlichen Richtung, insbesondere in Richtung eines Kindersitzes, und vom zweiten Fangband in einer Richtung quer zur gefährlichen Richtung begrenzt wird.According to one preferred embodiment provided that the expansion of the airbag from the first tether in the dangerous Direction, especially in the direction of a child seat, and the second Tether bounded in one direction transverse to the dangerous direction becomes.
Im übrigen kann die Zugspannung des zweiten Fangbandes einer Federung entgegenwirken, die die Sperr- und/oder Hemmvorrichtung in ihren Sperr- bzw. Hemmzustand spannt. Dabei kann das zweite Fangband gemäß einer besonders zweckmäßigen Ausgestaltung der Erfindung mit der Sperr- bzw. Hemmvorrichtung zugeordneten beweglichen Widerlagern der Federung gekoppelt sind.For the rest, can Counteract the tension of the second tether of a suspension, the blocking and / or inhibiting device in its blocking or inhibiting state stressed. In this case, the second tether according to a particularly advantageous embodiment the invention associated with the locking or inhibiting device movable Abutment of the suspension are coupled.
Herkömmliche Airbag-Anordnungen lassen sich mit der Erfindung nachrüsten, wenn die Fangbänder und die Sperr- bzw. Hemmvorrichtung außenseitig des Gehäuses des Gasgenerators angeordnet sind.conventional Airbag arrangements can be retrofitted with the invention if the tethers and the locking device outside the housing of the Gas generator are arranged.
Nachfolgend wird die Erfindung anhand der Zeichnung näher erläutert, in der bevorzugte Ausführungsformen der Erfindung dargestellt sind.following The invention will be explained in more detail with reference to the drawing, in the preferred embodiments the invention are shown.
