Abstract
Description
Die Erfindung betrifft ein Gassackmodul zum Einbau in das Lenkrad eines Kraftfahrzeugs nach dem Oberbegriff des Anspruchs 1.The The invention relates to a gas bag module for installation in the steering wheel of a Motor vehicle according to the preamble of claim 1.
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 Gassackmodulbodens können beispielsweise in Form von Positionierungsstiften ausgebildet sein. Als Befestigungsmittel dienen zumeist Schrauben. Grundsätzlich ist es auch möglich, Positionierungs- und Be festigungselemente des Gassackmodulbodens in einem Bauteil zusammenzufassen.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 gas bag module floor can be formed for example in the form of positioning pins. As fasteners are mostly screws. Basically it also possible Positioning and Be fastening elements of the gas bag module floor in a single component.
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 gattungsgemäßes 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 generic airbag module to further develop that very small and uniform gap dimensions between the gas bag 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.
Wie oben bereits erwähnt, weist der Boden des Gassackmoduls Positionierungselemente auf (diese können grundsätzlich gleichzeitig auch als Befestigungselemente dienen, im folgenden wird jedoch der Einfachheit halber ausschließlich von Positionierungselementen gesprochen).As already mentioned above, the bottom of the gas bag module has positioning elements (these can in principle at the same time serve as fasteners, in the following However, for the sake of simplicity, it will be exclusively of positioning elements spoken).
Erfindungsgemäß sind diese Positionierungselemente nun in einem nicht montierten Zustand beweglich bezüglich des Gehäuses mit dem Gassackmodul verbunden und können in einem montierten Zustand arretiert werden. Hierdurch wird es möglich, die endgültige Position der Positionierungselemente erst dann festzulegen, wenn alle übrigen Komponenten des Gassackmoduls zusammengesetzt sind. Die hierbei im Einzelfall ausgetretene Abweichung der Position des Abdekkelements von seiner Sollposition kann durch die Verschiebbarkeit der Positionierungselemente ausgeglichen werden.According to the invention these are Positioning now movable in a non-mounted state in terms of of the housing connected to the gas bag module and can in an assembled state be arrested. This makes it possible to get the final position of the positioning elements only if all other components the gas bag module are composed. The case in each case escaped deviation of the position of the Abdekkelements of his Target position can be determined by the displaceability of the positioning elements be compensated.
Vorzugsweise erfolgt die Justierung der Positionierungselemente in einem Justierwerkzeug, so dass der hierdurch zusätzlich notwendige Arbeitsschritt sehr schnell und präzise – gegebenenfalls auch vollautomatisch – ausgeführt werden kann.Preferably the adjustment of the positioning elements takes place in an adjusting tool, so that in addition necessary step very quickly and precisely - if necessary, also fully automatic - be executed can.
In einer ersten Ausführungsform ist das wenigstens eine Positionierungselement starr mit einer Befestigungsplatte verbunden, welche wiederum axial beweglich am Gehäuse angeordnet ist. Hier ist die Befestigungsplatte im nicht montierten Zustand in nichtaxialer Richtung, d.h. zumeist in radialer Richtung, beweglich am Gehäuse angeordnet und kann an diesem arretiert werden.In a first embodiment the at least one positioning element is rigid with a mounting plate connected, which in turn arranged axially movable on the housing is. Here is the mounting plate in the unassembled state in the non-axial direction, i. mostly in the radial direction, movable on the housing arranged and can be locked to this.
In einer zweiten Ausführungsform sind die Positionierungselemente selbst in ihrer Position veränderbar am Boden des Gassackmoduls angeordnet.In a second embodiment the positioning elements themselves are changeable in their position arranged at the bottom of the gas bag module.
Die Positionierungselemente sind vorzugsweise als Positionierungsstifte ausgebildet.The Positioning elements are preferably as positioning pins educated.
Weitere bevorzugte Ausführungsformen der Erfindung ergeben sich aus den weiteren Unteransprüchen sowie aus den nun mit Bezug auf die Figuren näher dargestellten Ausführungsbeispielen. Hierbei zeigen:Further preferred embodiments of Invention will become apparent from the other dependent claims and from the embodiments now shown in more detail with reference to the figures.
