Abstract
Description
Die vorliegende Erfindung betrifft ein aufblasbares Kopfschutzsystem für den Seitenbereich eines Kraftfahrzeugs gemäß dem Oberbegriff der Ansprüche 1 und 3.The The present invention relates to an inflatable head protection system for the Side area of a motor vehicle according to the preamble of claims 1 and Third
Ein derartiges Kopfschutzsystem entfaltet bei einem Unfall seinen Gassack zwischen dem Insassen und dem Seitenbereich des Kraftfahrzeuges. Der aufgeblasene Gassack reicht dabei von dem Dachrahmen bis etwa zum Schulterbereich des Fahrzeuginsassen und verhindert so ein Aufschlagen der entsprechenden Körperteile des Insassen gegen die Seitenscheiben und die umgebenden Seitenrahmenabschnitte der Fahrzeugkarosserie. In seiner Längsausdehnung kann sich dabei der aufgeblasene Gassack zwischen einer vorderen Karosseriesäule, der sogenannten A-Säule bis zur mittleren Karosseriesäule (B-Säule) oder aber bis zur hinteren Karosseriesäule, der C-Säule erstrecken.One Such head protection system unfolds his gas bag in an accident between the occupant and the side area of the motor vehicle. Of the inflated airbag ranges from the roof frame to about Shoulder area of the vehicle occupant and thus prevents a hit the corresponding body parts the occupant against the side windows and the surrounding side frame sections the vehicle body. In its longitudinal extent may be the inflated airbag between a front body pillar, the so-called A column to the middle body pillar (B-pillar) or to the rear body pillar, the C-pillar extend.
Bei Fahrzeugüberschlägen hat sich gezeigt, dass ein solches Kopfschutzsystem häufig den Fahrzeuginsassen nicht wirkungsvoll zurückhalten kann. Durch die Rotationsbewegung des Fahrzeuges taucht der Kopf des Fahrzeuginsassen unter dem Gassack hindurch und der nicht angeschnallte Insasse kann aus dem Fahrzeug geschleudert werden. Um den Schutz bei dieser Unfallsituation zu verbessern, müssten die aufblasbaren Kopfschutzsysteme in ihren Abmessungen wesentlich vergrößert werden mit der Folge einer erheblichen Kosten-, Massen- und Packagesteigerung.at Has vehicle rollovers It has been shown that such a head protection system often the Vehicle occupants can not withhold effectively. By the rotation movement of the vehicle, the head of the vehicle occupant dives under the gas bag through and the unbelted occupant can get out of the vehicle be hurled. To the protection in this accident situation too would have to improve the inflatable head protection systems in their dimensions essential be enlarged with the consequence of a considerable increase in costs, masses and packages.
Die
Aufgabe der Erfindung ist es, ein aufblasbares Kopfschutzsystem aufzuzeigen, bei dem der Gassack in seinen Abmessungen gegenüber einem herkömmlichen Gassack nicht vergrößert werden muss, der aber dennoch wirkungsvoll den Kopf des Insassen bei einem Fahrzeugüberschlag zurückhält.task the invention is to show an inflatable head protection system, in which the gas bag in its dimensions compared to a conventional Gas bag does not need to be enlarged, but still effective the head of the occupant in a vehicle rollover restrains.
Diese Aufgabe wird durch die kennzeichnenden Merkmale der Ansprüche 1 und 3 gelöst. Eine vorteilhafte Ausgestaltung der beanspruchten Lehre nach Anspruch 1 ergibt sich aus dem Unteranspruch 2.These The object is achieved by the characterizing features of claims 1 and 3 solved. An advantageous embodiment of the claimed teaching according to claim 1 results from the dependent claim 2.
Nach der Erfindung ist demnach im Gassack eine längliche, waagrecht ausgerichtete Ausnehmung oder ein länglicher Gewebestreifen vorgesehen. Überraschenderweise hat sich gezeigt, dass diese Maßnahmen bei einem Fahrzeugüberschlag in einem weit größeren Maße als herkömmliche Schutzsysteme den Kopf des Insassen zurückhalten vermögen. Dadurch können bereits in Kraftfahrzeugbau verwendete Kopfschutzsysteme nahezu kostenneutral für diesen zusätzlichen Anwendungsfall angepasst werden.To Accordingly, the invention is an elongated, horizontally oriented in the gas bag Recess or an elongated one Tissue strips provided. Surprisingly It has been shown that these measures in a vehicle rollover to a much greater extent than conventional ones Protective systems can restrain the occupant's head. Thereby can Already used in motor vehicle head protection systems almost cost neutral for this extra Use case to be adapted.
Durch die Maßnahme, die Ausnehmung bis zur vorderen Karosseriesäule zu verlängern und so den Gassack in diesem Bereich in einen unteren und oberen Abschnitt zu teilen, ergibt sich eine weitere Gestaltungsmöglichkeit. Der obere Abschnitt, er ist nicht an der Karosseriesäule festgelegt, lässt sich in seiner Geometrie nahezu frei auslegen und zwar in der Weise, dass er nach der Entfaltung die vordere Karosseriesäule abdeckt und somit verhindert, dass der sich nach seitlich vorne bewegenden Kopf des Insassen auf diesen Karosserieabschnitt aufschlägt.By the measure, extend the recess to the front body pillar and so the gas bag in to divide this area into a lower and upper section, This results in a further design option. The upper section, he is not at the body pillar set, lets to lay out in his geometry almost freely and in such a way, that he covers the front body pillar after unfolding and thus prevents it from moving laterally forward Head of the occupant hits this body section.
