Abstract

The folding structure rolls up an outboard side (1) of an airbag into a rolling fold and folds an inboard side (2) of the airbag into a U-shaped folded package (6). An upper end of the airbag lies on the outboard side of the airbag, and the U-shaped folded package is opened in an upward direction. Diameter of the rolling fold is 15 to 100 mm. A side length of the U-shaped folded package is 15 to 100 mm.

Description

Die vorliegende Erfindung beschreibt ein Faltschema für Luftsäcke insbesondere für Kopf-Airbags, auch Window oder Curtain-Airbags genannt.The present invention describes a folding scheme for air bags, especially for head airbags, also called window or curtain airbags.

Ein Kopf-Airbag muss bei seiner Aktivierung rechtzeitig in Position sein um so das Verletzungsrisiko der Insassen drastisch zu reduzieren. Der auf ein kleines Packvolumen gefaltete Luftsack wird in der Regel oben im Türrahmen hinter dem Verkleidungsteil „Himmel” platziert. Von dort aus muss sich der entfaltende Luftsack so bewegen, dass er den zu schützenden Fahrzeuginsassen möglichst nicht berührt und sich zwischen Insasse und Fahrzeugseitenscheibe positioniert.A head airbag must be in position when it is activated in order to drastically reduce the risk of injury to the occupants. The folded to a small packing volume airbag is usually placed at the top of the door frame behind the trim part "sky". From there, the unfolding airbag must move so that it does not touch the vehicle occupant to be protected as possible and positioned between the occupant and vehicle side window.

Aus dem Stand der Technik ist eine Vielzahl von Faltschemata bekannt, jedoch haben sie den Nachteil, dass sie nicht die gewünschte Stabilität in der Entfaltungsrichtung und -reproduzierbarkeit gewährleisten.A variety of folding schemes are known in the art, but they have the disadvantage of not providing the desired stability in deployment direction and reproducibility.

Die Erfindung hat zum Ziel diese Nachteile auszuräumen und ein einfaches Faltschema vorzuschlagen.The invention aims to overcome these disadvantages and to propose a simple folding scheme.

Das neue Faltschema ist in 1 dargestellt. Es handelt sich dabei um eine outboard-Rollfaltung mit anschließender inboard-U-Faltung. Das U ist nach oben geöffnet.The new folding scheme is in 1 shown. It is an outboard roll fold with a subsequent inboard U-fold. The U is open at the top.

Das Gas aus dem Gasgenerator strömt in den zusammengefalteten Luftsack, und zwar dort hin, wo es die geringste Arbeit zu verrichten hat, also der geringste Widerstand vorliegt.The gas from the gas generator flows into the folded airbag, there, where it has to do the least work, so there is the least resistance.

2 bis 5 zeigen die einzelnen Phasen der anfänglichen Entfaltung. Durch das nach oben geöffnete u-förmige Faltenpaket wird zunächst eine erste Gaskammer oberhalb des Faltenpaketes erzeugt und damit das Faltenpaket nach unten in Richtung Fensterscheibe beschleunigt. Das Faltenpaket wird dadurch in die richtige Entfaltungsrichtung gezwungen. Durch die Outboard-seitige Rollfaltung bedingt erfolgt die weitere Entfaltung nun wie angestrebt entlang der Fahrzeug-Fensterfront. 2 to 5 show the individual phases of the initial unfolding. By the upwardly open u-shaped fold package, a first gas chamber above the fold package is first generated and thus accelerates the fold package down towards the window. The fold package is thereby forced in the correct deployment direction. Due to the outboard-side roll folding, the further development now takes place as desired along the vehicle window front.
