Abstract
Description
Die Erfindung betrifft einen Vorhanggassack nach dem Oberbegriff des Anspruchs 1.The invention relates to a curtain airbag according to the preamble of claim 1.
Vorhanggassäcke werden im Bereich der Automobiltechnologie in großem Umfang benutzt. Solche Vorhanggassäcke dienen hauptsächlich dem Schutz des Kopfs eines Insassen im Fall eines seitlichen Aufpralls oder im Fall eines Überrollunfalls. Die Gassackhülle eines Vorhanggassacks umfasst im Allgemeinen zwei Seitenwände, welche einen Gasraum umschließen. Die Gassackhülle ist zu einem Paket gerollt und/oder gefaltet und an der inneren Struktur des Kraftfahrzeugs im Bereich des Dachholmes befestigt. Zu diesem Zweck ist der Gassack mit Befestigungselementen, meistens Befestigungslaschen, im Bereich der oberen Kante der Gassackhülle ausgestattet.Curtain gas bags are widely used in automotive technology. Such curtain bags serve primarily to protect the head of an occupant in the event of a side impact or in the event of a roll-over accident. The airbag cover of a curtain gas bag generally comprises two side walls, which enclose a gas space. The gas bag envelope is rolled into a package and / or folded and attached to the inner structure of the motor vehicle in the region of the roof spar. For this purpose, the gas bag is equipped with fastening elements, usually fastening straps, in the region of the upper edge of the airbag skin.
Im Stand der Technik ist bekannt geworden, den Gassack in der Art im Fahrzeug zu befestigen, dass die obere Kante der Gassackhülle nach unten zeigt und dass die Gassackhülle in einer Außenbordrolle zu einem Paket gerollt ist. Zwei Versionen dieser Geometrie sind verbreitet, welche manchmal als „p-Rolle” und als „b-Rolle” bezeichnet werden. Diese Anordnung hat den Vorteil, dass die expandierende Gassackhülle eine geringe Aggressivität gegen den Insassen zeigt, insbesondere wenn der Insasse nicht in seiner Standardposition ist. Ein Nachteil dieser Art der Montage und des Rollens des Gassacks ist, dass, wenn keine zusätzlichen Maßnahmen ergriffen werden, das Risiko besteht, dass die Gassackhülle während der Expansion an Teilen des Fahrzeugs, insbesondere der B-Säule, hängen bleibt.In the prior art it has become known to mount the gas bag in the vehicle in the manner that the upper edge of the airbag cover is pointing down and that the airbag cover is rolled in an outboard role to a package. Two versions of this geometry are common, sometimes called "p-roll" and "b-roll". This arrangement has the advantage that the expanding airbag cover shows a low aggressiveness against the occupant, especially when the occupant is not in his standard position. A disadvantage of this type of assembly and rolling of the airbag is that, if no additional measures are taken, there is a risk that the airbag cover during expansion on parts of the vehicle, in particular the B-pillar gets stuck.
Um dieses Problem zu lösen, schlägt die gattungsbildende
In der Geometrie, welche in der gattungsbildenden
Hiervon ausgehend stellt sich die vorliegende Erfindung die Aufgabe, einen gattungsgemäßen Vorhanggassack derart zu verbessern, dass die Leitkammer oder die Leitkammern mit größerer Höhe ausgebildet werden können, ohne den Durchmesser des gepackten Vorhanggassacks substantiell zu erhöhen und ohne Kompromisse in Bezug auf das Expansionsverhalten zu machen.On this basis, the present invention has the object to improve a generic curtain airbag so that the guide chamber or the guide chambers can be formed with greater height, without substantially increasing the diameter of the packed curtain gas bag and without compromising on the expansion behavior.
Diese Aufgabe wird durch einen Vorhanggassack mit den Merkmalen des Anspruchs 1 gelöst.This object is achieved by a curtain airbag with the features of claim 1.
In Ruhezustand des erfindungsgemäßen Vorhanggassacks zeigt die Gassackhülle der wenigstens einen Leitkammer wenigstens eine Falte, so dass die Leitkammer an dieser Stelle geknickt ist.In the idle state of the curtain gas bag according to the invention, the airbag envelope of the at least one guide chamber shows at least one fold, so that the guide chamber is bent at this point.
Diese Anordnung macht es möglich, einen Gassack mit einer höheren Leitkammer zur Verfügung zu stellen, ohne die Abmessungen des Pakets der Gassackhülle im Ruhezustand zu vergrößern und ohne Expansionsgeschwindigkeit und -genauigkeit der Leitkammer und so des gesamten Vorhanggassacks zu verlieren.This arrangement makes it possible to provide a gas bag with a higher guide chamber without increasing the dimensions of the package of the airbag cover at rest and without losing the expansion speed and accuracy of the guide chamber and thus the entire curtain gas bag.
