Abstract
Description
Die Erfindung betrifft ein Gassackmodul für eine Fahrzeuginsassen-Rückhaltevorrichtung, mit einem Gassack, einem Gasgenerator und einer steuerbaren Einrichtung, mit der der effektive Querschnitt von Einströmöffnungen veränderbar ist, durch die das vom Gasgenerator erzeugte Gas in den Gassack strömen kann.The The invention relates to a gas bag module for a vehicle occupant restraint device, with a gas bag, a gas generator and a controllable device, with the effective cross section of inlet openings changeable is, through which the gas generated by the gas generator can flow into the gas bag.

Die Erfindung schafft ein Gassackmodul, das eine effektivere Anpassung der in den Gassack einsströmenden Gasmenge ermöglicht.The The invention provides an airbag module that provides a more effective adaptation the air flowing into the gas bag Gas volume allows.
Gemäß der Erfindung ist bei einem Gassackmodul der eingangs genannten Art vorgesehen, daß mit der steuerbaren Einrichtung auch der effektive Querschnitt von Abströmöffnungen veränderbar ist, durch die das Gas in einen Freiraum außerhalb des Gassacks entweichen kann. Die Erfindung bietet somit erweiterte Möglichkeiten zur Anpassung der in den Gassack einzubringenden Gasmenge.According to the invention is provided in an airbag module of the type mentioned, that with the controllable device and the effective cross-section of outflow openings variable is, through which the gas escape into a space outside the gas bag can. The invention thus offers extended possibilities for the adaptation of in the gas bag to be introduced gas.
Eine besonders effiziente Veränderung der einströmenden Gasmenge kann durch eine Auslegung der steuerbaren Einrichtung dahingehend erreicht werden, daß eine Verringerung des effektiven Querschnitts der Einströmöffnungen gleichzeitig eine Vergrößerung des effektiven Querschnitts der Abströmöffnungen bewirkt. Durch das Schließen der Einströmöffnungen und die gleichzeitige Freigabe der Abströmöffnungen kann der Gassackinnendruck geringgehalten bzw. rasch abgebaut werden. Dies ist insbesondere dann von Bedeutung, wenn der Gassack beim Entfalten auf ein Hindernis oder auf einen sehr nahe am Gassackmodul befindlichen Insassen trifft.A particularly efficient change the inflowing Gas quantity may be due to a design of the controllable device be achieved that a Reduction of the effective cross section of the inlet openings at the same time an enlargement of the effective cross section of the outflow openings causes. By the Shut down the inflow openings and the simultaneous release of the outflow openings, the gas bag internal pressure can be kept low or degraded rapidly. This is especially important if the gas bag when unfolding on an obstacle or on a very meets occupant located near the gas bag module.
Die steuerbare Einrichtung kann einen Antrieb mit einem Elektromotor aufweisen, der eine stufenlose und reversible Einstellung ermöglicht, oder einen pyrotechnischen Antrieb, der eine besonders schnelle einmalige Einstellung ermöglicht.The controllable device can drive with an electric motor having a stepless and reversible adjustment, or a pyrotechnic drive, which is a particularly fast allows one-time adjustment.
Eine bevorzugte Ausführungsform der Erfindung sieht vor, daß das Gassackmodul einen Käfig zur Verteilung des vom Gasgenerator erzeugten Gases aufweist und daß die steuerbare Einrichtung einen Verdrehmechanismus aufweist, mit dem eine Blende relativ zum Käfig verdrehbar ist.A preferred embodiment the invention provides that the Airbag module a cage for Distribution of the gas generated by the gas generator and that the controllable Device having a twisting mechanism with which a diaphragm relative to the cage is rotatable.
Vorzugsweise sind im Käfig Einströmöffnungen und in einem festen Bauteil des Gassackmoduls Abströmöffnungen gebildet, deren effektive Querschnitte durch die Blende einstellbar sind.Preferably are in the cage inflow and in a solid component of the gas bag module outlet openings formed, whose effective cross-sections through the aperture adjustable are.
Die Erfindung schafft auch eine Fahrzeuginsassen-Rückhaltevorrichtung mit einem erfindungsgemäßen Gassackmodul, die eine elektronische Steuereinheit umfaßt, welche mit der steuerbaren Einheit des Gassackmoduls verbunden ist.The The invention also provides a vehicle occupant restraint with a gas bag module according to the invention, which comprises an electronic control unit connected to the controllable unit the gas bag module is connected.
Weitere Merkmale und Vorteile der Erfindung ergeben sich aus der nachfolgenden Beschreibung und aus der beigefügten Zeichnung, auf die Bezug genommen wird. In der Zeichnung zeigt die einzige Figur schematisch ein erfindungsgemäßes Gassackmodul.Further Features and advantages of the invention will become apparent from the following Description and from the attached Drawing to which reference is made. In the drawing shows the single figure schematically an inventive gas bag module.
