Abstract
Description
Die Erfindung betrifft ein Airbagmodul mit einem Gehäuse, einem in dem Gehäuse angeordneten Gasgenerator, einem diesen wenigstens teilweise umschließenden und mit dem Gehäuse verbundenen Diffusor und mit einem von einer Gehäuseabdeckung übergriffenen, auf den Diffusor gefalteten Gassack.The The invention relates to an airbag module having a housing, a gas generator arranged in the housing, a latter at least partially enclosing and connected to the housing diffuser and with a housing cover overlapped, Airbag folded on the diffuser.
Ein
Airbagmodul mit den vorgenannten Merkmalen ist in der
Mit dem bekannten Airbagmodul ist der Nachteil verbunden, dass für die Halterung des Gasgenerators neben der Gehäusebaugruppe eine zusätzliche Befestigungsmöglichkeit bereitzustellen ist, so dass Herstellung und Montage der Halterung des Gasgenerators entsprechend aufwendig sind; es kommt hinzu, dass Airbagmodule insbesondere für die Fahrerseite bei verschiedenen Fahrzeugen in unterschiedlichen Einbausituationen eingebaut werden, wobei nur in einem Teil der Einbaufälle die Anordnung von Schwingungstilgern erforderlich ist. Somit sind in Abhängigkeit von den jeweiligen Einbaugegebenheiten unterschiedliche Bauformen von Airbagmodulen vorzuhalten.With the known airbag module has the disadvantage that for the holder of the gas generator next to the housing assembly an additional mounting option to provide, so that manufacture and assembly of the holder the gas generator are correspondingly expensive; it is added that Airbag modules in particular for Driver side on different vehicles in different installation situations be installed, only in a part of the installation cases the Arrangement of vibration absorbers is required. Thus, in dependence from the respective installation conditions different designs of airbag modules.
Der Erfindung liegt daher die Aufgabe zugrunde, ein Airbagmodul mit den gattungsgemäßen Merkmalen derart weiterzubilden, dass Herstellung und Montage des Airbagmoduls vereinfacht und die Bauweise der Airbagmodule standardisierbar ist.Of the Invention is therefore the object of an airbag module with the generic features in such a way that the manufacture and assembly of the airbag module simplified and the design of the airbag modules can be standardized.
Die Lösung dieser Aufgabe ergibt sich einschließlich vorteilhafter Ausgestaltungen und Weiterbildungen der Erfindung aus dem Inhalt der Patentansprüche, welche dieser Beschreibung nachgestellt sind.The solution This object is achieved including advantageous embodiments and further developments of the invention from the content of the claims, which read this description.
Die Erfindung sieht in ihrem Grundgedanken vor, dass der Gasgenerator ohne eine Verbindung mit dem Gehäuse über Halterungen unmittelbar am Diffusor gehaltert ist. Mit der Erfindung ist der Vorteil verbunden, dass aufgrund der Verbindung von Diffusor und Gasgenerator eine Vormontage dieser Bauteile zu einer Baugruppe möglich ist, die anschließend nur noch in an sich bekannter Weise mit dem Gehäuse des Airbagmoduls zu verbinden ist. Im Hinblick auf die wahlweise Auslegung des Airbagmoduls ohne und mit Schwingungstilgern sind keine besonderen konstruktiven Änderungen des Airbagmoduls erforderlich. Damit bleiben die Einbauverhältnisse des Airbagmoduls gleich, und insbesondere tritt keine Änderung bei dem Packen des gefalteten Gassacks in das Gehäuse des Airbagmoduls ein.The The invention provides in its basic idea that the gas generator without a connection to the housing via brackets is held directly on the diffuser. With the invention is the Advantage connected that due to the connection of diffuser and Gas generator a pre-assembly of these components to an assembly possible is that, then only to be connected in a conventional manner with the housing of the airbag module is. With regard to the optional design of the airbag module without and with vibration absorbers are no special constructive changes the airbag module required. Thus the installation conditions of the Airbag module equal, and in particular, no change occurs in the packing of the folded airbag into the housing of the Airbag module on.
Nach einem Ausführungsbeispiel der Erfindung ist vorgesehen, dass der Gasgenerator über entsprechend starr ausgebildete Halterungen fest mit dem Diffusor verbunden ist, wobei beispielsweise durch eine entsprechende Geometrie der Halterungen die erforderliche Steifheit einstellbar ist.To an embodiment The invention provides that the gas generator via accordingly rigidly formed mounts firmly connected to the diffuser, for example, by a corresponding geometry of the brackets the required stiffness is adjustable.
Alternativ kann vorgesehen sein, dass der Gasgenerator über die Halterungen relativ beweglich zum Diffusor angeordnet ist; durch eine bewegliche Aufhängung des Gasgenerators am Diffusor wirkt der Gasgenerator selbst aufgrund seines vergleichsweise großen Gewichts als Schwingungstilger, so dass auf gesonderte Bauteile verzichtet werden kann; hiermit sind Montage und Herstellung des Airbagmoduls vereinfacht.alternative can be provided that the gas generator relative to the brackets is movably arranged to the diffuser; by a movable suspension of the Gas generator on the diffuser affects the gas generator itself due its comparatively large Weight as a vibration absorber, allowing for separate components can be dispensed with; herewith are assembly and production of Airbag module simplified.
Vorzugsweise sind die Halterungen als Federelemente ausgebildet, die nach einem Ausführungsbeispiel die Form von geschwungenen Befestigungsstegen haben können.Preferably the brackets are designed as spring elements, which after a embodiment may have the shape of curved mounting webs.
Soweit nach einem Ausführungsbeispiel der Erfindung die Halterungen bzw. die Federelemente einstückig mit dem Diffusor verbunden sein können, ergibt sich eine vorteilhafte Ausführungsform der Erfindung dadurch, dass die Halterungen als aus der Wandung des Diffusors herausgetrennte Laschen gebildet sind.So far according to an embodiment the invention, the brackets and the spring elements integral with can be connected to the diffuser results an advantageous embodiment the invention in that the brackets as out of the wall formed out of the diffuser tabs are formed.
Alternativ können die Halterungen aber auch als gesonderte Bauteile ausgebildet und an dem Diffusor festlegbar, beispielsweise aufgrund einer entsprechenden Ausbildung von Diffusor und Halterungen miteinander verrastbar sein.alternative can the brackets but also designed as separate components and can be fixed to the diffuser, for example due to a corresponding Training of diffuser and brackets can be locked together.
Zum Anschluss des Gasgenerators an die Halterungen kann der Gasgenerator an seinem äußeren Umfang mit einem Flansch versehen sein, an dem die Halterungen mit ihren vom Diffusor nach innen wegstehenden Enden angreifen und mit dem Gasgenerator vorzugsweise im Wege einer Rastverbindung verbunden sind. Hierbei ist nach einem Ausführungsbeispiel der Erfindung vorgesehen, dass die freien inneren Enden der Halterungen untereinander zu einem Rastkranz verbunden sind, der seinerseits mit dem Umfangsflansch des Gasgenerators verrastet.To connect the gas generator to the brackets, the gas generator may be provided at its outer periphery with a flange on which the brackets engage with their ends projecting inwardly from the diffuser and are preferably connected to the gas generator by way of a snap connection. Here is after an Off guide embodiment of the invention provided that the free inner ends of the brackets are interconnected to a latching ring, which in turn is locked to the peripheral flange of the gas generator.
Vorzugsweise bestehen die Halterungen aus Metall, so dass bei der Herstellung des Airbagmoduls im Gegensatz zum Stand der Technik nicht unterschiedliche Materialien verarbeitet werden müssen, soweit beispielsweise im Stand der Technik die Schwingungstilger aus einem Elastomermaterial bestehen.Preferably The brackets are made of metal, so that in the production the airbag module in contrast to the prior art is not different Materials must be processed, as far as possible For example, in the prior art, the vibration damper from a Elastomer material exist.
In vorteilhafter Weise ist eine Standardisierung des Airbagmoduls dann gegeben, wenn die an dem Diffusor befindlichen Halterungen grundsätzlich beweglich ausgebildet sind und für Anwendungsfälle einer starren Festlegung des Gasgenerators gegenüber dem Diffusor ein gesondertes Bauteil vorgesehen ist, mittels dessen die beweglichen Halterungen gegenüber dem Diffusor festlegbar sind, so dass dadurch die gewünschte starre Verbindung zwischen Gasgenerator und Diffusor verwirklicht wird. Hierbei kann es sich beispielsweise um einen an der Innenwandung des Diffusors einschiebbaren Ring handeln, der die abstehenden Enden der Halterungen untergreift und diese dadurch festlegt.In Advantageously, a standardization of the airbag module is then given when the mounts located on the diffuser basically movable are trained and for Use cases of a rigid definition of the gas generator relative to the diffuser a separate Component is provided, by means of which the movable mounts against the Diffuser are fixable, thereby making the desired rigid Connection between gas generator and diffuser is realized. This may be, for example, one on the inner wall of the diffuser retractable ring acting on the projecting ends engages under the holders and this determines.
Bei einer derartigen beweglichen Aufhängung des Gasgenerators am Diffusor kann die Anpassung der Eigenfrequenz des Systems durch Änderung der Geometrie, der Vorspannung, des Materials oder teilweises Weglassen der Federelemente erfolgen.at such a movable suspension of the gas generator on Diffuser can adjust the natural frequency of the system by changing geometry, preload, material or partial omission the spring elements take place.
