Abstract
Description
Die Erfindung betrifft ein Seitenairbagmodul für ein Kraftfahrzeug nach dem Oberbegriff des Patentanspruches 1.The The invention relates to a side airbag module for a motor vehicle according to the preamble of claim 1.
Abgestimmt auf den jeweiligen Unfalltyp können unterschiedliche Airbagsysteme im Kraftfahrzeug eingebaut sein. Frontairbags und auch Seitenairbags für Fahrer und Beifahrer gehören dabei zur Standardausstattung von Kraftfahrzeugen. Frontairbags sind im Lenkrad oder in der Instrumententafel integriert und schützen bei einem Frontalaufprall den Kopf oder die Brust der Fahrzeuginsassen. Seitenairbags entfalten sich demgegenüber bei Seitenkollisionen zwischen dem Fahrzeugsitz und der Türverkleidung und reduzieren so das Verletzungsrisiko im Brustkorbbereich.Voted Different airbag systems can be adapted to the respective type of accident be installed in the vehicle. Front airbags and also side airbags for driver and passenger are standard equipment of motor vehicles. Front airbags are integrated in the steering wheel or in the instrument panel and protect the head or the head in a frontal impact Chest of the vehicle occupants. Side airbags unfold in contrast in side collisions between the vehicle seat and the door panel and thus reduce the risk of injury in the ribcage area.
Zusätzlich zum Seitenairbag kann im Dachrahmen des Kraftfahrzeuges ein Kopfairbag integriert sein. Der Kopfairbag entfaltet sich bei einer Seitenkollision entlang der seitlichen Fensterfront nach unten und schützt den Kopf des Fahrzeuginsassen bei einem Seitenaufprall oder einem Überschlag des Fahrzeuges.additionally To the side airbag can in the roof frame of the motor vehicle, a head airbag be integrated. The head airbag unfolds in a side collision down along the side window and protects the head of the vehicle occupant in a side impact or rollover of the vehicle.
Alternativ dazu kann der Kopfairbag in einem sogenannten Kopf-Thorax-Airbag unmittelbar als eine Kopfkammer im Luftsack integriert sein. So weist ein gattungsgemäßes Seitenairbagmodul einen Luftsack auf, der sich bei einer Seitenkollision zwischen dem Fahrzeugsitz und der Türverkleidung entfaltet. Der Luftsack ist mit einer Brustkammer und einer Kopfkammer ausgebildet, die mittels einer Überströmöffnung strömungstechnisch miteinander verbunden sind. Derartige kombinierte Kopf-Thorax-Airbags kommen insbesondere auch bei Cabriolets zum Einsatz, bei denen eine Kopfairbag-Montage im Dachrahmen nicht möglich ist.alternative In addition, the head airbag in a so-called head-thorax airbag be integrated directly as a head chamber in the airbag. So points a generic side airbag module an airbag on, resulting in a side collision between the vehicle seat and the door panel unfolds. The airbag is with a chest chamber and a head chamber formed by means of an overflow opening fluidically connected to each other. Such combined head-thorax airbags come especially with convertibles are used, in which a Head airbag installation in the roof frame is not possible.
Bei Aktivierung eines solchen Seitenairbags entfaltet sich zunächst die Brustkammer in Fahrzeuglängsrichtung nach vorne entlang des Brustbereiches des Fahrzeuginsassen. Anschließend schießt die Kopfkammer in Fahrzeughochrichtung nach oben bis auf Höhe des Kopfes des Fahrzeuginsassen. Bei Kopfaufprall-Simulationen hat sich allerdings eine genaue Abstimmung auf die richtige Luftsackhärte im Kopfkammerbereich des Luftsackes als schwierig erwiesen.at Activation of such a side airbag unfolds first the chest chamber in the vehicle longitudinal direction along the front the chest area of the vehicle occupant. Then shoot the head chamber in vehicle vertical direction up to height the head of the vehicle occupant. In head impact simulations has However, an exact vote on the right airbag hardness proved to be difficult in the head chamber area of the airbag.
Aus
der
Die Aufgabe der Erfindung besteht darin, ein Seitenairbagmodul bereitzustellen, dessen Luftsack im entfalteten Zustand insbesondere in seiner Kopfkammer eine für einen Kopfaufprall geeignete Luftsackhärte aufweist.The The object of the invention is to provide a side airbag module, the airbag in the deployed state, especially in his head chamber an air bag hardness suitable for a head impact having.
Die Aufgabe ist durch die Merkmale des Patentanspruches 1 gelöst. Vorteilhafte Weiterbildungen der Erfindung sind in den Unteransprüchen offenbart.The The object is solved by the features of claim 1. Advantageous developments of the invention are in the dependent claims disclosed.
Gemäß dem kennzeichnenden Teil des Patentanspruches 1 weist die Kopfkammer des Luftsacks zumindest eine Entlüftungsöffnung auf, mittels der bei ausgelöstem Seitenairbagmodul die Luftsackhärte im Bereich der Kopfkammer einstellbar ist. Die Luftsackhärte im Kopfkammerbereich kann hierbei unabhängig von der Luftsackhärte im Brustkammerbereich abgestimmt werden.According to the Characterizing part of claim 1, the head chamber of the airbag at least one vent opening on, by means of the triggered side airbag module the Air bag hardness in the head chamber is adjustable. The airbag hardness in the head chamber area can be independent matched by the airbag hardness in the chest area become.
Demgegenüber kann in Kombination zur Entlüftungsöffnung in der Kopfkammer auch in der Brustkammer eine Entlüftungsöffnung vorgesehen werden. Auf diese Weise können sowohl in der Kopf- als auch Brustkammer unabhängig voneinander jeweils die Luftsackhärten eingestellt werden.In contrast, Can be used in combination with the vent in the head chamber also in the chest chamber a vent be provided. In this way, both in the Head and chest independent of each other the air bag hardnesses are adjusted.
Bei Aktivierung des Seitenairbagmoduls entfaltet sich zunächst üblicherweise der Luftsack im Brustkammerbereich. Anschließend entfaltet sich dessen Kopfkammer nach oben. Das Gasgemisch strömt dabei durch eine Überströmöffnung von der Brustkammer in die Kopfkammer.at Activation of the side airbag module initially unfolds usually the airbag in the chest area. Then unfolded his head chamber upwards. The gas mixture flows thereby through an overflow opening of the chest chamber into the head chamber.
In der Kopfkammer kann durch eine flächige Vernähung von gegenüberliegenden Gewebeabschnitten der Luftkammer ein Strömungsleitabschnitt, das heißt ein sogenanntes Fangband, gebildet werden, das das einströmende Gas unmittelbar zu einem theoretisch vorbestimmten Kopfaufschlagbereich der Kopfkammer führt.In The head chamber can be made by a flat suturing from opposite tissue sections of the air chamber a Strömungsleitabschnitt, that is a so-called Tether, are formed, which the inflowing gas directly to a theoretically predetermined head impact area of the head chamber leads.
Bevorzugt ist dabei die Strömungsführung in der Kopfkammer derart, dass das einströmende. Gas zunächst weg von der Entlüftungsöffnung geleitet wird, um ein vorzeitiges Entweichen aus der Luftabströmöffnung zu vermeiden. Bevorzugt kann daher der oben genannte Strömungsleitabschnitt zwischen dem theoretisch vorbestimmten Kopfaufschlagbereich und der Entlüftungsöffnung angeordnet sein.Prefers is the flow guide in the head chamber such that the incoming. Gas away first from the vent is routed to a premature escape from the air outlet to avoid. Preferably, therefore, the above-mentioned Strömungsleitabschnitt between the theoretically predetermined head impact area and be arranged the vent.
Eine unmittelbare Anordnung der Entlüftungsöffnung im Bereich des wahrscheinhichen Kopfaufschlages würde demgegenüber zu einer geringeren Luftsackhärte der Kopfkammer führen. In diesem Fall wäre das Risiko eines Kopfdurchschlages gegeben.A immediate arrangement of the vent in the area of probscheinhichen head impact would in contrast lead to a lower airbag hardness of the head chamber. In that case, there would be a risk of head-bleeding given.
In einer bevorzugten Ausführungsform kann die Entlüftungsöffnung in Fahrzeuglängsrichtung im hinteren Bereich der Kopfkammer angeordnet sein, während der wahrscheinliche Kopfaufschlagbereich im vorderen Bereich der Kopfkammer angeordnet ist.In In a preferred embodiment, the vent opening in the vehicle longitudinal direction in the rear of the head chamber be arranged while the probable head impact area in the front portion of the head chamber is arranged.
Demgegenüber kann die Entlüftungsöffnung der Brustkammer in Fahrzeuglängsrichtung in deren vorderem Bereich angeordnet sein.In contrast, can the vent of the chest chamber in Vehicle longitudinal direction arranged in the front area be.
