Abstract
Description
Die Erfindung betrifft ein Fahrzeuginsassen-Rückhaltesystem mit einem gefaltet im Bereich eines Dachrahmens aufgenommenen Seitengassack, der einen vorderen Abschnitt aufweist, welcher sich im entfalteten Zustand von einer A-Säule des Fahrzeugs ausgehend erstreckt, der einen ersten, schlauchförmigen aufblasbaren Bereich aufweist, welcher im entfalteten Zustand längs der A-Säule verläuft, und der einen zweiten aufblasbaren Bereich aufweist, welcher im entfalteten Zustand unterhalb des ersten aufblasbaren Bereichs entlang eines unteren Randes des Seitengassacks verläuft.The The invention relates to a vehicle occupant restraint system with a folded in the area of a roof frame received side airbag, the one having front portion, which is in the deployed state from an A-pillar of the vehicle starting, comprising a first, tubular inflatable area which extends in the deployed state along the A-pillar, and a second Inflatable area, which in the unfolded state below the first inflatable area along a lower edge of the side gas bag runs.
Eine Klasse von Seitengassäcken sind die vorhangartigen Gassäcke, die vor ihrer Aktivierung im Bereich des Dachrahmens, oft auch durchgehend von der A- bis zur C-Säule des Fahrzeugs, untergebracht sind. Bei der Entfaltung tritt der Gassack aus der Dach- bzw. Säulenverkleidung aus und erstreckt sich schließlich wie ein Vorhang über die Seitenscheiben des Fahrzeugs. Um Füllgas zu sparen und Entfaltungsgeschwindigkeit zu gewinnen, können gezielt zwischen aufblasbaren Kammern nicht aufblasbare Bereiche an Stellen vorgesehen sein, an denen ein Kontakt mit einem Fahrzeuginsassen ausgeschlossen ist.A Class of side airbags are the curtain-like airbags, the before their activation in the area of the roof frame, often also from the A to the C-pillar of the Vehicle, are housed. During deployment, the gas bag occurs from the roof or pillar cladding and finally extends like a curtain over the side windows of the vehicle. To save filling gas and deployment speed to win targeted between inflatable chambers not inflatable areas be provided at locations where a contact with a vehicle occupant is excluded.
Aufgabe der Erfindung ist es, einen Seitengassack bei einem Fahrzeuginsassen-Rückhaltesystem zu verbessern.task The invention is a side airbag in a vehicle occupant restraint system to improve.
Hierzu ist bei einem oben genannten Fahrzeuginsassen-Rückhaltesystem vorgesehen, daß in Längsrichtung des Seitengassacks die Dicke des zweiten aufblasbaren Bereichs in wenigstens einer Richtung senkrecht zur Längsrichtung im wesentlichen kontinuierlich zunimmt, d.h. er besitzt auch keine Einschnitte. Durch diese Ausführung wird bei einem Seitenaufprall der Hals- und untere Kopfbereich durch den zweiten aufblasbaren Bereich unterstützt, wobei ein Abknicken im Halsbereich verhindert wird. Die zum vorderen Fahrzeugende geneigten Flächen helfen, z.B. bei einem Schrägaufprall, den Fahrzeuginsassen in einen vorzugsweise vorhandenen Frontgassack zu leiten.For this is provided in an above-mentioned vehicle occupant restraint system that in the longitudinal direction of the side gas bag the thickness of the second inflatable area in at least one direction perpendicular to the longitudinal direction substantially continuously increases, i. he also has no cuts. Through this design In a side impact, the neck and lower head area will go through the second inflatable area is supported, with a kink in the Neck area is prevented. The inclined to the front end of the vehicle Aids help e.g. in an oblique impact, the vehicle occupant in a preferably existing front airbag to lead.
Die Höhe und/oder die Breite des zweiten aufblasbaren Bereichs kann im vorderen Abschnitt des Seitengassacks in Längsrichtung annähernd linear zunehmen.The Height and / or the width of the second inflatable area may be in the front portion of the Side airbag in the longitudinal direction nearly increase linearly.
Vorzugsweise nimmt ein Querschnitt des zweiten aufblasbaren Bereichs in einer Ebene senkrecht zur Längsrichtung im wesentlichen kontinuierlich zu.Preferably takes a cross section of the second inflatable area in one Plane perpendicular to the longitudinal direction essentially continuously too.
In einer bevorzugten Ausführungsform erweitert sich der zweite aufblasbare Bereich in Längsrichtung gesehen annähernd kegelförmig. Hierbei vergrößert sich die Ausdehnung des zweiten aufblasbaren Bereichs nicht nur in der Höhe, also in z-Richtung des Fahrzeugs, sondern auch horizontal in der Breite, also in y-Richtung.In a preferred embodiment the second inflatable area widens in the longitudinal direction seen approximately conical. This increases the expansion of the second inflatable area not only in the Height, so in the z-direction of the vehicle, but also horizontally in width, ie in the y direction.
Der erste und der zweite aufblasbare Bereich sind vorzugsweise durch einen nicht aufblasbaren Bereich miteinander verbunden. Die hauptsächliche Wirkung beim Auffangen eines Fahrzeuginsassen wird vom zweiten aufblasbaren Bereich erzielt. Der erste aufblasbare Bereich dient primär dazu, eine A-Säulenverkleidung zu öffnen, um das Austreten des Gassacks zu ermöglichen. Infolgedessen kann die Dicke des ersten aufblasbaren Bereichs in der in den Fahrzeuginnenraum hineinweisenden y-Richtung deutlich kleiner gewählt werden als die Dicke des zweiten aufblasbaren Bereichs in dieser Richtung.Of the first and second inflatable areas are preferably through a non-inflatable area interconnected. The main effect when intercepting a vehicle occupant becomes inflatable from the second Scored area. The first inflatable area is primarily used an A-pillar paneling to open, to allow the escape of the gas bag. As a result, the Thickness of the first inflatable area in the vehicle interior in y direction be chosen smaller than the thickness of the second inflatable area in this direction.
Die beiden aufblasbaren Bereiche können an einem vorderen Ende des Gassacks strömungsmäßig getrennt sein, so daß zumindest im vorderen Abschnitt des Seitengassacks keine Strömungsverbindung zwischen den beiden aufblasbaren Bereichen besteht. Es ließen sich aber auch eine oder mehrere Strömungsverbindungen vorsehen. Beispielsweise kann eine Strömungsverbindung zwischen den beiden aufblasbaren Bereichen nur im Bereich eines vorderen Endes des Seitengassacks bestehen. In diesem Fall laufen die beiden aufblasbaren Bereiche am vorderen Ende des Gassacks V-förmig aufeinander zu.The Both inflatable areas can be attached be fluidly separated a front end of the gas bag, so that at least no flow connection in the front section of the side gas bag between the two inflatable areas. It settled but also one or more flow connections provide. For example, a flow connection between the both inflatable areas only in the area of a front end of the side gas bag. In this case, the two inflatable areas run at the front end of the gas bag V-shaped toward each other.
Vorzugsweise beträgt der Winkel zwischen dem ersten aufblasbaren Bereich und einem unteren Rand des zweiten aufblasbaren Bereichs im vorderen Abschnitt des Seitengassacks höchstens 60°. Die Form des Gassacks kann sich dabei dem Design moderner Personenkraftwagen anpassen, bei denen die A-Säule in einem relativ flachen Winkel ansteigt.Preferably is the angle between the first inflatable area and a lower edge of the second inflatable area in the front portion of the side gas bag at the most 60 °. The The shape of the gas bag can be the design of modern passenger cars adjust where the A-pillar rises at a relatively shallow angle.
Die Erfindung wird im folgenden anhand eines Ausführungsbeispiels und der beigefügten Zeichnung näher erläutert. Die einzige Figur zeigt eine schematische Ansicht eines erfindungsgemäßen Fahrzeuginsassen-Rückhaltesystems mit einem aufgeblasenen Seitengassack.The Invention will be described below with reference to an embodiment and the accompanying drawings explained in more detail. The single figure shows a schematic view of a vehicle occupant restraint system according to the invention with an inflated side gas bag.
