Abstract
Description
Die Erfindung betrifft eine airbagbestückte Sicherheitsvorrichtung gemäß dem Oberbegriff des Patentanspruchs 1.The The invention relates to an airbag-equipped safety device according to the generic term of claim 1.
Der Einsatz von Airbags in Kraftfahrzeugen zum Schutz der Insassen ist seit langem bekannt. Dabei sind die Airbags so angeordnet, dass sie bei einem auftretenden Crash zwischen der kräftebeaufschlagten Stelle des Fahrzeuges einerseits und dem Fahrzeuginsassen, insbesondere dessen Kopf, andererseits liegen. Dadurch verringern sie relativ weich, nämlich über einen bestimmten Deformationsweg, die in Folge des Crashs auftretende Relativgeschwindigkeit zwischen dem Fahrzeug einerseits und insbesondere dem Kopf des Fahrzeuginsassen andererseits.The Use of airbags in motor vehicles to protect occupants known for a long time. The airbags are arranged so that in the event of a crash between the point of the Vehicle on the one hand and the vehicle occupant, especially his Upside down, on the other hand. This makes them decrease relatively softly, namely about one certain deformation path that occurs as a result of the crash Relative speed between the vehicle on the one hand and in particular the head of the vehicle occupant, on the other hand.
Der Erfindung liegt die Aufgabe zugrunde, eine gattungsgemäße Sicherheitsvorrichtung zu schaffen, die in erster Linie dazu geeignet ist, bei einem Crash auftretende Beschleunigungen und Verlagerungen von Ladegut, insbesondere auf einer Ladefläche des Fahrzeuges, für davorsitzende Fahrzeuginsassen praktisch ungefährlich zu machen.The The invention is based on the object of a generic safety device to create, which is primarily suitable for a crash Accelerating and relocating loads, in particular on a loading area of the vehicle, for make vehicle passengers sitting in front practically harmless.
Die erfindungsgemäße Lösung der Aufgabe besteht in einer gattungsgemäßen Sicherheitsvorrichtung mit den kennzeichnenden Merkmalen des Hauptanspruchs, vorteilhafte Ausgestaltungen der Erfindung beschreiben die Unteransprüche.The solution of the invention The task consists in a generic safety device with the characterizing features of the main claim, advantageous Embodiments of the invention describe the subclaims.
In der einfachsten Ausführung ist die Materialbahn ein „Doppeltuch", das wie ein Sack aufblasbar ist zum Airbag.In the simplest version the material web is a "double cloth" that is like a sack is inflatable to the airbag.
Da sich bei der Erfindung die einen wesentlichen Bestandteil der Sicherheitsvorrichtung bildende Materialbahn mit ihren Airbags nur im Crashfall – und wenn sie bewusst von Hand entsprechend bewegt worden ist – in ihrer Betriebslage befindet, in der sie gleichsam eine Querwand im Fahrzeuginnenraum bildet, stört die erfindungsgemäße Sicherheitsvorrichtung den Fahrkomfort bei normalem Fahrbetrieb nicht. Die Verwendung von Airbags, sei es in Gestalt von Kammern in der Materialbahn, sei es in Gestalt von an der Materialbahn äußerlich festgelegten Airbags, sorgt dafür, dass insbesondere bei einem Frontcrash in Richtung nach vorn kraftbeaufschlagte Ladungsgüter über einen durch die aufgeblasenen Airbags definierten Deformationsweg abgebremst werden, sie also nie mit voller Wucht insbesondere den Kopf vor ihnen befindlicher Fahrzeuginsassen treffen und gefährliche Verletzungen hervorrufen.There the invention is an essential part of the safety device forming material web with its airbags only in the event of a crash - and when she has been deliberately moved accordingly by hand - in her Operating position, in which it forms, as it were, a transverse wall in the vehicle interior, disturbs the safety device according to the invention the driving comfort during normal driving is not. The use of Airbags, be it in the form of chambers in the material web it in the form of airbags externally attached to the material web, ensures that especially in the event of a front crash in the direction of forwardly loaded goods over a are slowed down by the deformation path defined by the inflated airbags, so they never with full force especially the head in front of them Vehicle occupants meet and dangerous Cause injury.
Die erfindungsgemäße Sicherheitsvorrichtung kann jedoch auch zum Schutz auf vorderen Sitzen befindlicher Fahrzeuginsassen gegen gefährliche Berührungen durch hinter ihnen sitzende Fahrzeuginsassen bei einem Frontalcrash dienen, indem nämlich die Materialbahn mit den Airbags sich in ihrer Betriebslage vor den hinteren Fahrzeuginsassen, insbesondere ihren Köpfen und ihren Oberkörpern, befindet. Entsprechend kann die Erfindung dem Kopfschutz der hinteren Fahrzeuginsassen dienen.The safety device according to the invention can also be used to protect vehicle occupants in front seats against dangerous touches by vehicle occupants sitting behind them in a frontal crash serve by namely the web of material with the airbags is in its operating position the rear vehicle occupants, especially their heads and their upper bodies. According to the invention, the head protection of the rear vehicle occupants serve.
Im folgenden werden Ausführungsbeispiele der Erfindung anhand der Zeichnung erläutert. In dieser zeigen:in the the following are embodiments of the Invention explained with reference to the drawing. In this show:

Auch hier stehen die verschiedenen Airbags bei einem Crash mit hier nicht gezeichneten Gasgeneratoren in Verbindung.Also here the various airbags are not in the event of a crash drawn gas generators in connection.
Bei
einem Frontalcrash bietet Airbag
Um mit Sicherheit unerwünschte Berührungen der Materialbahn mit einer Sitzrückenlehne oder einer darauf angebrachten Kopfstütze bei einem Crash zu vermeiden, kann es zweckmäßig sein, bei einer längsverstellbaren Rückenlehne, wobei die Längsverstellung durch Längsverstellung des gesamten Sitzes oder aber durch Änderung der Lehnenneigung erzeugt sein kann, eine die jeweilige Position der Rückenlehne erfassende Sensierung vorzusehen, die bei extremen rückwärtigen Lagen der Rückenlehne den Bewegungsantrieb der Materialbahn wirkungslos macht.Around certainly undesirable touches the material web with a seat back or avoid having a headrest attached to it in the event of a crash, it can be useful with a length adjustable Backrest, being the longitudinal adjustment through longitudinal adjustment of the entire seat or generated by changing the backrest angle can be a sensation sensing the respective position of the backrest to be provided for extreme rear positions the backrest makes the movement drive of the material web ineffective.
Mit der Erfindung ist demgemäss eine gattungsgemäße Sicherheitsvorrichtung geschaffen, die in Folge ihrer dachnahen Lage in ihrer Ruhestellung den Fahrkomfort im normalen Fahrbetrieb nicht beeinträchtigt.With the invention is accordingly a generic safety device created, which due to their position close to the roof in their rest position Driving comfort is not impaired in normal driving.
