Abstract
Description
Die Erfindung betrifft ein Verfahren zum Zusammenlegen eines Gassacks. Die Erfindung betrifft außerdem eine Vorrichtung zum Falten eines Gassacks. Die Erfindung betrifft schließlich einen zusammengelegten Gassack.The The invention relates to a method for collapsing a gas bag. The invention also relates a device for folding a gas bag. The invention relates after all a folded gas bag.
Ein solcher Gassack ist Teil eines Fahrzeuginsassen-Rückhaltesystems, mit dem ein Fahrzeuginsasse vor Verletzungen geschützt werden soll. Im Bedarfsfall muß der Gassack möglichst schnell aus einem platzsparend zusammengelegten Zustand in einen entfalteten Zustand überführt werden. Hierbei spielt unter anderem die Art und Weise eine Rolle, wie der Gassack zusammengelegt wurde, da sowohl die Entfaltungsgeschwindigkeit als auch die Entfaltungsrichtung eines Gassacks dadurch beeinflußt werden können, wie die Wandung zusammengelegt wurde.One such airbag is part of a vehicle occupant restraint system, to protect a vehicle occupant from injury should. If necessary, the Gas bag possible quickly from a space-saving folded state into one unfolded state. Among other things, the way plays a role, such as the Gas bag was folded, as both the deployment speed as well as the deployment direction of a gas bag are affected can, how the wall was folded.
Im Stand der Technik ist eine Vielzahl von Verfahren bekannt, um einen Gassack platzsparend zusammenzulegen. Die meisten Verfahren bestehen aus einer Vielzahl von einzelnen, präzise definierten Faltschritten. Außerdem sind Verfahren bekannt, bei denen der Gassack im wesentlichen zusammengeschoben wird, so daß kein präzise gefalteter Gassack, sondern ein zusammengelegter Gassack mit mindestens abstützweise chaotisch verlaufender Wandung erhalten wird.in the Prior art is a variety of methods known to a Collapse gas bag to save space. Most procedures consist of a variety of individual, precise defined folding steps. Furthermore Methods are known in which the airbag substantially pushed together will, so that no precise folded gas bag, but a collapsed airbag with at least abstützweise chaotically extending wall is obtained.
Die Aufgabe der Erfindung besteht darin, ein Verfahren zum Zusammenlegen eines Gassacks zu schaffen, das sich durch einen geringen Aufwand auszeichnet. Die Aufgabe der Erfindung besteht außerdem darin, eine Vorrichtung zum Zusammenlegen des Gassacks zu schaffen. Die Aufgabe der Erfindung besteht schließlich darin, einen mit einfachen Mitteln zusammengelegten Gassack zu schaffen.The The object of the invention is a method for folding to create an airbag that is characterized by a low cost. The object of the invention is also a device to create the collapse of the gas bag. The object of the invention finally exists to create a simple gas bag.
Zur Lösung dieser Aufgabe ist erfindungsgemäß ein Verfahren zum Zusammenlegen eines Gassacks vorgesehen, welches die folgenden Schritte enthält: Zunächst wird der Gassack flach auf einer Unterlage ausgebreitet. Dann wird ein ringförmiger Außenbereich des Gassacks, der einen Mittelbereich umgibt, um etwa 90° abgeklappt, so daß der Außenbereich den Mittelbereich schürzenförmig umgibt. Schließlich wird der Außenbereich zur Unterlage hin zusammengeschoben. Auf diese Weise läßt sich mit geringem Aufwand ein platzsparend zusammengelegter Gassack erhalten. Besonders vorteilhaft ist dabei, daß die Wandung sich größtenteils in einem Ring befindet, der den Mittelbereich des Gassacks umgibt. Dieses Verfahren ist insbesondere für sogenannte Doughnut-Gassäcke geeignet, also für Gassäcke, die im wesentlichen aus einem schlauchförmigen Wulst bestehen.to solution This object is a method according to the invention provided for collapsing a gas bag, which includes the following Steps contains: First The gas bag is spread flat on a base. Then it will be a ring-shaped outdoor area of the gas bag, which surrounds a central region, folded down by about 90 °, so that the outdoors surrounds the middle area apron-shaped. Finally will the outdoor area pushed together to the pad. In this way can be obtained with little effort a space-saving folded together gas bag. It is particularly advantageous that the wall is largely located in a ring surrounding the central area of the gas bag. This Procedure is especially for so-called donut gas bags suitable, ie for Airbags, the consist essentially of a tubular bead.
Zur Lösung der obengenannten Aufgabe ist auch eine Vorrichtung zum Zusammenlegen eines Gassacks vorgesehen, die dadurch gekennzeichnet ist, daß sie eine Unterlage aufweist, die aus einem feststehenden Mittelabschnitt und einem klappbaren Außenabschnitt besteht, sowie einen ringförmigen Außenstempel, dessen Außendurchmesser etwa dem Außendurchmesser des Mittelabschnitts entspricht und der aus einer Ausgangsstellung in eine gegen die Unterlage gedrückte Faltstellung verstellt werden kann. Diese Vorrichtung zeichnet sich dadurch aus, daß der Gassack mit sehr geringem Aufwand in eine topfförmige Gestalt gebracht werden kann, aus der heraus er mit geringem Aufwand zusammengeschoben werden kann.to solution The above object is also a device for folding a gas bag, which is characterized in that it has a Pad has, consisting of a fixed central portion and a hinged outer section exists, as well as an annular outer stamp, its outer diameter about the outside diameter corresponds to the middle section and the from a starting position in a pressed against the pad Faltstellung can be adjusted. This device stands out characterized in that the Airbag can be brought into a pot-shaped shape with very little effort, out of which he can be pushed together with little effort can.
Die oben genannte Aufgabe wird schließlich gelöst durch einen zusammengelegten Gassack, der dadurch gekennzeichnet ist, daß er einen flachausgebreiteten Mittelbereich aufweist und einen diesen umgebenden Ringbereich, in welchem die Wandung des Gassacks chaotisch zusammengeschoben ist.The The above object is finally solved by a collapsed Airbag, characterized in that it has a flat-distributed central region and a surrounding annular region in which the Wall of the gas bag is pushed together messy.
Vorteilhafte Ausgestaltungen der Erfindung ergeben sich aus den Unteransprüchen.advantageous Embodiments of the invention will become apparent from the dependent claims.
Die Erfindung wird nachfolgenden anhand einer bevorzugten Ausführungsform beschrieben, die in den beigefügten Zeichnungen dargestellt ist. In diesen zeigen.The Invention will be described below with reference to a preferred embodiment described in the attached Drawings is shown. In this show.
