Description
Die Erfindung betrifft einen Gassack für ein Fahrzeuginsassen-Rückhaltesystem, insbesondere einen Beifahrer-Gassack, nach dem Oberbegriff des Anspruchs 1.The The invention relates to a gas bag for a vehicle occupant restraint system, in particular a passenger gas bag, according to the preamble of the claim 1.
Ein
solcher Gassack ist beispielsweise aus der US 2003/0116951 A1 bekannt.
In der
Gassack-Module, die in der Nähe der Windschutzscheibe des Fahrzeugs angeordnet sind, versprechen einige Vorteile gegenüber herkömmlichen Gassack-Modulen, die auf der dem Fahrzeuginsassen zugewandten Seite der Armaturentafel angeordnet sind, also üblicherweise knapp oberhalb des Handschuhfachs. Zum einen weist ein nahe der Windschutzscheibe angeordnetes Gassack-Modul eine Abdeckkappe auf, die in einem Bereich angeordnet ist, der für einen Fahrzeuginsassen üblicherweise nicht zugänglich ist. Zum anderen ergeben sich bei der Gestaltung des Armaturenbretts größere Freiräume.Airbag modules, the nearby the windshield of the vehicle are arranged, promise some advantages over conventional gas bag modules on arranged the vehicle occupants facing side of the instrument panel are, so usually just above the glove box. For one thing, one near the windshield arranged airbag module on a cap on which in one area is arranged for a vehicle occupant usually inaccessible is. On the other hand arise in the design of the dashboard bigger open spaces.
Sowohl für Gassack-Module, die in der Nähe der Windschutzscheibe des Fahrzeugs angeordnet sind, als auch für herkömmliche, im Bereich des Handschuhfachs angeordnete Gassack-Module sind dreidimensionale Gassäcke bekannt. Der Begriff „dreidimensional" bezieht sich auf das Herstellungsverfahren für die Gassäcke, insbesondere auf die Nähte, mittels denen die einzelnen Gewebeteile des Gassacks zusammengenäht werden. Unter den Begriff „dreidimensionaler Gassack" wird dabei ein Gassack verstanden, dessen Nähte drei dimensional verlaufen, also nicht flach in einer Ebene ausgebreitet werden können und daher auch nicht durchgehend auf einer üblichen Nähmaschine genäht werden können. Eine solche Naht muß in kurze Abschnitte unterteilt werden, wobei nach dem Nähen jedes Abschnittes das Gewebe geeignet nachgeführt werden muß.Either for gas bag modules, the near the Windshield of the vehicle are arranged, as well as for conventional, Airbag modules arranged in the area of the glove compartment are three-dimensional airbags known. The term "three-dimensional" refers to the manufacturing process for the gas bags, especially on the seams, by means of which the individual tissue parts of the gas bag are sewn together. Under the term "three-dimensional Airbag "is included understood an airbag whose seams three dimensional, so do not spread flat in a plane can and therefore not be sewn continuously on a conventional sewing machine can. Such a seam must be in short sections are divided, wherein after sewing each Section the tissue must be tracked suitable.
Aus Gründen der einfacheren Herstellung sind daher zweidimensionale Gassäcke wünschenswert, also Gassäcke, bei denen jede Naht eben verläuft, so daß sie durchgehend auf einer üblichen Nähmaschine genäht werden kann.Out establish For ease of manufacture, therefore, two-dimensional airbags are desirable. so gas bags, where each seam runs flat, so that you consistently on a usual sewing machine stitched can be.
Die Erfindung schafft einen zweidimensional nähbaren Beifahrer-Gassack, der im entfalteten Zustand dieselbe Form und dasselbe Volumen hat wie die bisher bekannten dreidimensionalen Gassäcke, jedoch aufgrund des Verlaufs seiner Nähte und seiner Zuschnittsformen mit sehr viel geringerem Aufwand herstellbar ist. Dies wird bei einem gattungsgemäßen Gassack durch die kennzeichnenden Merkmale des Anspruchs 1 erreicht. Der erfindungsgemäße Gassack kann, im entfalteten Zustand, von der Form verglichen werden mit einer Socke, deren Sohle dem Fahrzeuginsassen als Prallfläche zugewandt ist, wobei die Ferse der Sohle nach oben, also zum Dachhimmel zeigt und die Fußspitze zum Fahrzeugboden zeigt. Dieser Gassack ist vorzugsweise am vom Fußteil der Socke abgewandten Ende am Gassack-Modul angebracht. Das Frontteil bildet dabei die dem Fahrzeuginsassen zugewandte Prallfläche des Gassacks sowie den dem Fahrzeugboden zugewandten Bereich des Gassacks.The The invention provides a two-dimensionally seamable passenger airbag, the in the unfolded state has the same shape and volume as the previously known three-dimensional gas bags, but due to the course his seams and its blank forms produced with much less effort is. This is in a generic airbag by the characterizing Features of claim 1 achieved. The gas bag according to the invention can be compared in the unfolded state of the form with a sock whose sole faces the vehicle occupant as a baffle, the heel of the sole pointing upwards, ie to the headliner and the toe to the vehicle floor shows. This gas bag is preferably on the footboard the sock remote end attached to the gas bag module. The front part forms the impact of the airbag facing the vehicle occupant and the vehicle floor facing the area of the gas bag.
