Abstract
Description
Die Erfindung betrifft eine Fahrzeuginsassen-Rückhaltevorrichtung mit einem Gassack, einer Befüllvorrichtung zur Bereitstellung eines Füllgases für den Gassack, einem im Gassack angeordneten Fangband und einer Einrichtung zur selektiven Änderung des Gassackinnendrucks.The The invention relates to a vehicle occupant restraint device having a Airbag, a filling device for providing a filling gas for the gas bag, an arranged in the airbag tether and a device for selective change the gas bag interior pressure.
Zur Anpassung des Gassackinnendrucks sind viele verschiedene Maßnahmen bekanntgeworden, z.B. der Einsatz aktiver Ventile, um ein Abströmen des Füllgases zu ermöglichen, oder sogenannte Bi-Volume-Airbags, die unter bestimmten Umständen ihr Volumen vergrößern, so daß sich der Gassackinnendruck verringert. Nachteilig bei diesen Maßnahmen ist, daß eine Sensierung bestimmter Parameter (z.B. des Gewichts des Fahrzeuginsassen) und eventuell zusätzliche Zündkreise zur Aktivierung der Ventile oder anderer pyrotechnischer Hilfsmittel erforderlich sind.to Adaptation of the gas bag interior pressure are many different measures have become known, e.g. the use of active valves to prevent the filling gas to enable or so-called bi-volume airbags that under certain circumstances her Increase volume, so that yourself the gas bag pressure decreases. A disadvantage of these measures is that one Sensing certain parameters (e.g., the weight of the vehicle occupant) and possibly additional ignition circuits required to activate the valves or other pyrotechnic aids are.
Eine Fahrzeuginsassen-Rückhaltevorrichtung der eingangs genannten Art ist aus der DE 10 2004 027 703 A1 bekannt. Bei dieser Vorrichtung ist ein Gassack an einem Halteblech eines Gassackmoduls befestigt, das auch den Gasgenerator trägt. In dem Halteblech sind zwischen den Befestigungsstellen des Gassacks und dem Gasgenerator Klappen vorgesehen, die Abströmöffnungen im Halteblech für das Füllgas schließen oder freigeben. Die Klappen sind jeweils mit einem Ende eines Fangbands verbunden, dessen anderes Ende an der gegenüberliegenden Gassackwand befestigt ist. Bei unbehinderter Entfaltung des Gassacks dehnen sich die Fangbänder im Laufe der Entfaltung, so daß die Klappen die Abströmöffnungen schließen und der Gassack mit vollem Druck aufgeblasen wird. Trifft der sich entfaltende Gassack aber auf ein Hindernis, oder kommt ein sehr nahe am Gassackmodul befindlicher Insasse während der Entfaltungsphase in Kontakt mit dem Gassack, bleiben die Fangbänder in einem lockeren Zustand, so daß die Klappen in ihrer Öffnungsstellung verbleiben und die Abströmöffnungen freigeben. In diesem Fall wird der Gassack nicht mit vollem Druck aufgeblasen.A Vehicle occupant restraint device of the aforementioned type is known from DE 10 2004 027 703 A1. In this device, an airbag to a retaining plate of a Gas bag module attached, which also carries the gas generator. By doing Bracket are between the attachment points of the gas bag and provided the gas generator flaps, close the outflow openings in the holding plate for the filling gas or release. The flaps are each with one end of a tether connected, the other end attached to the opposite gas bag wall is. In unobstructed deployment of the gas bag, the tethers stretch in Course of unfolding, so that the Fold the outflow openings shut down and the gas bag is inflated at full pressure. Meets that unfolding gas bag but on an obstacle, or comes a very Inmate near the airbag module during the deployment phase in contact with the gas bag, the tethers remain in a loose state, So that the Flaps in their open position remain and the outflow openings release. In this case, the gas bag will not be at full pressure inflated.
Die Erfindung schafft eine Fahrzeuginsassen-Rückhaltevorrichtung, die eine situationsspezifische, insbesondere vom Entfaltungsverhalten des Gassacks abhängige Anpassung des Gassackinnendrucks erlaubt.The The invention provides a vehicle occupant restraint device comprising a situation-specific, in particular the deployment behavior of the gas bag dependent Adaptation of the gas bag internal pressure allowed.
Erfindungsgemäß wird dies durch eine Fahrzeuginsassen-Rückhaltevorrichtung der eingangs genannten Art erreicht, bei der das Fangband an eine vorzugsweise elektrische Steuerung gekoppelt ist, mit der die Einrichtung zur selektiven Änderung des Gassackinnendrucks betätigt wird. Während der Entfaltung des Gassacks gibt die Dehnung des Fangbands an, inwieweit sich der Gassack in eine bestimmte Richtung frei entfaltet oder behindert wird. Nach einer vollständigen Entfaltung des Gassacks kann eine Verminderung der Zugkraft im Fangband das Eintauchen eines Insassen mit hoher kinetischer Energie bedeuten. Die Kopplung des Fangbands an die elektrische Steuerung ermöglicht in all diesen Fällen eine optimale Anpassung des Gassackinnendrucks.According to the invention this is by a vehicle occupant restraint reaches the type mentioned, in which the tether to a preferably electrical control is coupled with which the device for selective change of the gas bag interior pressure is actuated becomes. While the development of the gas bag indicates the expansion of the tether, to what extent the airbag unfolds freely in a certain direction or is hampered. After a complete deployment of the gas bag can a reduction of the tensile force in the tether the immersion of a Inmates with high kinetic energy mean. The coupling of the Tether to the electric control allows in all these cases optimal adaptation of the gas bag internal pressure.
Je nach Auslegung der grundsätzlich vorgesehenen Füllgasmenge für den Gassack kann für die Anpassung des Gassackinnendrucks ein Druckabbau oder eine Druckerhöhung sinnvoll sein. Die Einrichtung zur selektiven Änderung des Gassackinnendrucks kann entsprechend dem ersten Fall ein Ventil zur selektiven Freigabe einer Abströmöffnung für das Füllgas oder eine Einrichtung zur Vergrößerung des effektiven Gassackvolumens umfassen. Entsprechend dem zweiten Fall kann die Einrichtung zur selektiven Änderung des Gassackinnendrucks eine weitere Füllgasquelle umfassen. Es können auch zwei (oder mehr) Einrichtungen vorgesehen sein – eine zum Druckabbau und eine zur Druckerhöhung.ever after interpretation of the principle provided filling gas for the Airbag can for the adaptation of the gas bag interior pressure makes a pressure reduction or an increase in pressure meaningful be. The device for selectively changing the gas bag internal pressure can according to the first case, a valve for selective release a discharge opening for the filling gas or a device for increasing the effective Gas bag volume include. According to the second case, the Selective change facility the gas bag internal pressure comprise a further filling gas source. There can also be two (or more) facilities are provided - one for pressure reduction and one for pressure increase.
Bei der bevorzugten Ausführungsform der Erfindung greift das Fangband an einem elektrischen Schalter an. So kann die Einrichtung zur selektiven Änderung des Gassackinnendrucks auf einfache Weise elektrisch betätigt werden.at the preferred embodiment the invention engages the tether on an electrical switch at. Thus, the means for selectively changing the gas bag internal pressure be electrically operated in a simple manner.
Der Begriff „Fangband" ist allgemein als Oberbegriff für alle geeigneten mechanischen, im Gassackinneren angeordneten Verbindungen zwischen der dem Fahrzeuginsassen zugewandten Gassackwand und einem festen Bauteil des Gassackmoduls zu verstehen.Of the The term "tether" is generally used as a generic term for all suitable mechanical, arranged in the gas bag interior compounds between the vehicle occupant facing gas bag wall and a to understand solid component of the gas bag module.
