Abstract
Description
Die Erfindung betrifft ein Gassackmodul nach dem Oberbegriff des Anspruchs 1 und ein Verfahren zu seiner Herstellung nach Anspruch 16.The The invention relates to a gas bag module according to the preamble of the claim 1 and a method for its production according to claim 16.
In nahezu jedem Lenkrad eines modernen Kraftfahrzeuges ist ein Gassackmodul angeordnet, welches dazu dient, einen Gassack im Falle eines Unfalls vor dem Lenkrad aufzublasen und somit den Fahrer bei einem Frontalzusammenstoß zu schützen. In den allermeisten Fällen ist hierbei das Gassackmodul im Nabenbereich angeordnet, wozu der Lenkradkörper eine Ausnehmung aufweist, in welche das Gassackmodul aufgenommen ist. Häufig soll die Oberfläche auch als Betätigungsfläche für die Hupe dienen, so dass das Abdeckelement, welches das Gassackmodul abdeckt, bezüglich des Lenkradkörpers axial niedergedrückt werden kann. Hierzu ist es einerseits bekannt, das Gehäuse des Gassackmoduls starr mit dem Lenkradkörper zu verbinden und das Abdeckelement beweglich bezüglich des Gehäuses anzuordnen. Weiterhin ist es bekannt, das Abdeckelement starr am Gehäuse des Gassackmoduls anzuordnen und das Gehäuse gegen die Kraft wenigstens eines Federelementes beweglich am Lenkradkörper anzuordnen. Hierbei weist das Gassackmodul häufig eine Befestigungsplatte auf, welche über Federn und zumeist auch Führungen mit dem Gehäuse verbunden ist.In Almost every steering wheel of a modern motor vehicle is an airbag module arranged, which serves to a gas bag in the event of an accident inflate in front of the steering wheel and thus protect the driver in a frontal collision. In most of the cases in this case, the gas bag module is arranged in the hub region, including the steering wheel body a Has recess in which the gas bag module is received. Often should the surface also serve as an actuating surface for the horn, so that the cover element, which covers the gas bag module, with respect to the steering wheel body axially depressed can be. For this purpose, it is known on the one hand, the housing of the Gas bag module rigidly connect to the steering wheel body and the cover movable with respect of the housing to arrange. Furthermore, it is known that the cover rigidly on casing to arrange the gas bag module and the housing against the force at least to arrange a spring element movable on the steering wheel body. Hereby points the gas bag module frequently a mounting plate on which springs and usually also guides with the housing connected is.
Das gesamte Modul kann dann bei der Endmontage sehr leicht im Lenkradkörper angeordnet werden. Zur exakten Positionierung des Gassackmoduls im Lenkradkörper weist der Boden des Gassackmoduls zumeist Positionierungselemente und der Lenkradkörper hierzu komplementäre Positionierungselemente auf. Die Positionierungselemente des Modulbodens können beispielsweise in Form von Positionierungszapfen ausgebildet sein. Als Befestigungsmittel dienen zumeist Schrauben.The entire module can then be easily arranged in the final assembly in the steering wheel body. For exact positioning of the gas bag module in the steering wheel body has the bottom of the gas bag module mostly positioning elements and the steering wheel body complementary thereto Positioning elements on. The positioning elements of the module bottom can be formed for example in the form of positioning pin. As fasteners are mostly screws.
Dadurch, dass das Abdeckelement axial beweglich bezüglich des Lenkradkörpers angeordnet ist, ist es notwendig, einen Spalt zwischen Abdeckelement und Lenkradkörper vorzusehen. Der notwendige Spalt soll hierbei so schmal und so gleichmäßig wie möglich sein. Insbesondere wenn das Abdeckelement starr mit dem Gehäuse des Gassackmoduls verbunden ist, wenn also beim Betätigen der Hupe das Gehäuse mit dem Abdeckelement heruntergedrückt wird, besteht hier folgendes Problem: Das Gassackmodul besteht aus einer Mehrzahl aneinander montierter Bestandteile, die jedes für sich und hinsichtlich der Montage aneinander eine gewisse Toleranz aufweisen. Soll der Spalt zwischen Abdeckelement und Lenkradkörper in radialer Richtung sehr klein und gleichmäßig sein, müssen daher sehr hohe Anforderungen an die Maßhaltigkeit der Einzelkomponenten des Gassackmoduls gestellt werden.Thereby, the cover element is arranged to be axially movable with respect to the steering wheel body, it is necessary to provide a gap between cover and steering wheel body. The necessary gap should be as narrow and as even as possible possible be. In particular, when the cover rigidly connected to the housing of the Gas bag module is connected, so if when pressing the horn with the housing pressed down the cover Here is the following problem: The gas bag module consists of a plurality of components mounted together, each for itself and in terms of the assembly to each other have a certain tolerance. Should he Gap between cover and steering wheel body in the radial direction very small and be even have to therefore very high demands on the dimensional accuracy of the individual components the gas bag module are placed.
Hiervon ausgehend stellt sich die vorliegende Erfindung die Aufgabe, ein Gassackmodul dahingehend weiterzubilden, dass sehr kleine und gleichmäßige Spaltmaße zwischen Gassackmodul und Lenkradkörper erreicht werden können, ohne dass es notwendig wird, hohe Anforderungen an die Maßhaltigkeit der Einzelkomponenten des Gassackmoduls zu stellen.Of these, Based on the object of the present invention, a Further developing the gas bag module so that very small and uniform gap dimensions between Airbag module and steering wheel body can be achieved without it becoming necessary, high dimensional stability requirements the individual components of the gas bag module to provide.
Diese Aufgabe wird durch ein Gassackmodul mit den Merkmalen des Anspruchs 1 gelöst.These The object is achieved by an airbag module with the features of the claim 1 solved.
Es ist eine weitere Aufgabe der Erfindung, ein Verfahren zur Herstellung eines solchen Gassackmoduls zur Verfügung zu stellen.It Another object of the invention is a method of preparation to provide such a gas bag module.
Diese Aufgabe wird durch ein Verfahren mit den Merkmalen des Anspruchs 16 gelöst.These The object is achieved by a method having the features of the claim 16 solved.
Der Modulboden des Gassackmoduls weist wenigstens einen, vorzugsweise zwei oder drei Positionierungszapfen auf. Erfindungsgemäß ist der Positionierungszapfen das vordere Ende eines Stiftes, welcher unter Verformung des Modulbodens und/oder unter Verformung des Stiftes in den Modulboden eingepresst ist. Hierdurch wird es möglich, den Positionierungszapfen erst dann anzuordnen und somit seine Position festzulegen, wenn die übrigen Montageschritte zur Herstellung des Gassackmoduls abgeschlossen sind. Hierdurch wird die Position der als Positionierungselemnte dienenden Positionierungszapfen bezüglich des Abdeckelementes erst zu einem Zeitpunkt festgelegt, wenn alle anderen Montageschritte abgeschlossen sind, so dass sich dann Abweichungen vom Idealwert kompensieren lassen. Selbst wenn der ungünstigste Fall auftritt, dass sich bei der Montage alle Toleranzen in eine Richtung aufaddieren, kann dies durch die späte Festlegung der Position der Positionierungszapfen ausgeglichen werden.Of the Module bottom of the gas bag module has at least one, preferably two or three positioning pins on. According to the invention Positioning pin the front end of a pin, which under Deformation of the module bottom and / or deformation of the pin is pressed into the module bottom. This makes it possible, the Positioning pin only then arrange and thus its position set if the rest Completed assembly steps for the production of the gas bag module are. This will change the position of the positioner serving positioning pin with respect to the cover only set at a time when all other assembly steps are completed, so that then deviations from the ideal value compensate. Even if the worst case occurs, that adding up all tolerances in one direction during assembly, This can be done by late fixing be compensated for the position of the positioning pin.
