Abstract
Vorhanggassack-Einheit für ein Kraftfahrzeug mit einem eine Oberkante (12) aufweisenden Gassack (10), welcher im montierten Zustand als Gassackpaket (11) vorliegt, und Befestigungselementen (20) zur Befestigung des Gassackpakets (11) im Bereich eines Dachholmes des Kraftfahrzeugs, wobei wenigstens ein Befestigungselement (20) eine erste Halteplatte (22) aufweist, von welcher sich ein mit dieser Halteplatte (22) dauerhaft verbundener Arm erstreckt, welcher das Gassackpaket (11) umgreift, und an dessen Ende eine zweite Halteplatte (32) angeordnet ist, wobei erste Halteplatte (22) und zweite Halteplatte (32) jeweils eine Durchbrechung (23, 33) haben, welche übereinanderliegen und durch die sich eine Schraube oder ein Clips erstreckt, welcher auch zur Montage der Vorhanggassack-Einheit am Fahrzeug dient, dadurch gekennzeichnet, dass der Gassack (10) zumindest teilweise zum Gassackpaket (11) gerollt ist und die Oberkante (12) des Gassacks (10) mit der ersten Halteplatte (22) des Befestigungselements (20), welche im montierten Zustand näher zur Innenstruktur des Kraftfahrzeugs liegt als die zweite Halteplatte (32), durch Vernähen, Verkleben oder Verschweißen verbunden ist.Curtain airbag unit for a motor vehicle having an upper edge (12) having gas bag (10) which is present in the assembled state as a gas bag package (11), and fastening elements (20) for fastening the airbag package (11) in the region of a roof rail of the motor vehicle, said at least one fastening element (20) has a first retaining plate (22) from which extends an arm permanently connected to this retaining plate (22), which encompasses the airbag package (11) and at the end of which a second retaining plate (32) is arranged, wherein the first holding plate (22) and the second holding plate (32) each have an opening (23, 33) which lie one above the other and through which a screw or clip extends, which also serves to mount the curtain-gas bag unit on the vehicle, characterized the gas bag (10) is rolled at least partially to the gas bag package (11) and the upper edge (12) of the gas bag (10) is connected to the first holding plate (22) of the fastening device ngselements (20), which in the assembled state is closer to the inner structure of the motor vehicle than the second retaining plate (32) is connected by sewing, gluing or welding.
Description
Die Erfindung betrifft eine Vorhanggassack-Einheit nach dem Oberbegriff des Anspruchs 1.The invention relates to a curtain airbag unit according to the preamble of claim 1.
Der Gassack einer Vorhanggassack-Einheit ist stets im Bereich des Dachholms des Kraftfahrzeugs mit der Innenstruktur des Kraftfahrzeuges verbunden. Im Ruhezustand ist der Gassack gerollt oder gefaltet und entfaltet sich bei Betätigung eines zugeordneten Gasgenerators vor den Seitenscheiben und vor einer gegebenenfalls vorhandenen B-Säule. Es müssen somit sowohl Mittel vorhanden sein, mittels denen die Oberkante des Gassacks mit der Innenstruktur des Kraftfahrzeugs verbunden ist, als auch Mittel, mit denen der Gassack im Ruhezustand in seiner gerollten oder gefalteten Position gehalten wird.The gas bag of a curtain gas bag unit is always connected in the region of the roof rail of the motor vehicle with the inner structure of the motor vehicle. At rest, the gas bag is rolled or folded and unfolds on actuation of an associated gas generator in front of the side windows and in front of any existing B-pillar. Thus, both means must be present, by means of which the upper edge of the gas bag is connected to the inner structure of the motor vehicle, as well as means by which the gas bag is held in its rested state in its rolled or folded position.

Hiervon ausgehend stellt sich die Erfindung die Aufgabe, eine gattungsgemäße Gassack-Einheit dahingehend weiterzubilden, dass ein verbessertes und vorhersagbares Aufblasverhalten erreicht wird. Weiterhin soll die Vorhang-Einheit einfach herstellbar sein.On this basis, the invention has the object to develop a generic airbag unit to the effect that an improved and predictable inflation behavior is achieved. Furthermore, the curtain unit should be easy to produce.
Diese Aufgabe wird durch eine Vorhanggassack-Einheit mit den Merkmalen des Anspruchs 1 gelöst.This object is achieved by a curtain airbag unit with the features of claim 1.
Erfindungsgemäß ist die Halteplatte des Befestigungselements, welche im montierten Zustand näher zur Innenstruktur des Kraftfahrzeugs liegt als die zweite Halteplatte, mit einem Abschnitt der Oberkante des Gassacks vernäht, verklebt oder verschweißt. Ein solcher Verbindungsprozess ist einfach durchzuführen, wobei das Vernähen im allgemeinen zu bevorzugen ist. Anschließend wird der Gassack in das Befestigungselement hinein gerollt und dann das Befestigungselement geschlossen. Es entfällt somit die Notwendigkeit, das gerollte oder gefaltete Gassackpaket zusammenzuhalten, während das Befestigungselement um das Paket herumgeführt wird.According to the invention, the retaining plate of the fastening element, which in the mounted state is closer to the inner structure of the motor vehicle than the second retaining plate, is sewn, glued or welded to a section of the upper edge of the gas bag. Such a bonding process is easy to perform, with stitching generally being preferred. Subsequently, the gas bag is rolled into the fastener and then closed the fastener. It thus eliminates the need for rolled or folded Airbag package together while the fastener is guided around the package.
Durch das Befestigen des Gassacks in der beschriebenen Art ist das Gassackpaket unmittelbar mit seiner Mantelfläche am Befestigungselement befestigt. Hierdurch ist ein Verdrehen des Gassackpaketes bezüglich dem Befestigungselement ausgeschlossen.By attaching the gas bag in the manner described, the airbag package is attached directly to its lateral surface on the fastening element. As a result, a rotation of the airbag package is excluded with respect to the fastener.
