Gemäß dem kennzeichnenden Teil des Patentanspruches 1 ist das Gehäuse des Airbagmoduls mit einem Führungsspalt ausgebildet, in den der dem Gasgenerator zugeordnete Gasverteiler ragt. In Abhängigkeit von seiner Länge und räumlichen Ausrichtung kann der Ort und die Richtung der Airbagentfaltung gezielt beeinflusst werden. Zugleich kann das den Airbag-Stauraum und den Gasgenerator begrenzende Modulgehäuseteil in einem vom Fußraum entfernten, bauraumgünstigen Fahrzeugbereich angeordnet werden, wodurch der Fußraum entsprechend vergrößerbar ist.According to the characterizing one Part of claim 1 is the housing of the airbag module with a guide gap formed in the gas distributor associated with the gas distributor protrudes. Dependent on of his length and spatial Alignment can target the location and direction of airbag deployment to be influenced. At the same time, this can limit the airbag storage space and the gas generator Module housing part in a distance from the footwell, space-low Vehicle area are arranged, whereby the footwell accordingly is enlargeable.
Erfindungsgemäß kann der Airbag mit einer Gewebelage einlagig um den Gasverteiler bzw. um dessen stirnseitige Gasausblasöffnung geführt werden. Bei Aktivierung des Airbagmoduls kann somit der Airbag einlagig aus dem Führungsspalt in den Insassenraum gezogen werden. Dadurch werden die weiteren Gewebelagen des Airbags nacheinander entfaltet, ohne dass das zusammengefaltete Airbagpaket als Ganzes ausgeworfen und entfaltet wird.According to the invention of Airbag with a fabric layer in one layer around the gas distributor or to the latter frontal gas exhaust opening guided become. Upon activation of the airbag module thus the airbag can be single-layered from the guide gap be pulled into the passenger compartment. This will make the others Fabric layers of the airbag unfolded one after another without the folded Airbag package is ejected as a whole and unfolded.
Bevorzugt weist das Modulgehäuse für den zusammengefalteten Airbag einen Stauraum auf, der unmittelbar in den Führungsspalt übergehen kann. Zur Reduzierung des Bauraums sowie für eine sichere Airbag-Entfaltung ist es bevorzugt, wenn der Stauraum des zusammengefalteten Airbags auf der von einem Fußraum abgewandten Seite des Gasverteilers angeordnet ist. Der zusammengefaltete Airbag ist hier zwischen dem langgestreckten Gasverteiler und einer Gehauseinnenwand verstaut. Dabei kann bevorzugt die einlagige Gewebelage des Airbags auf der, dem Fußraum zugewandten Seite des Gasverteilers befestigt sein.Prefers has the module housing for the folded Airbag a storage space, which pass directly into the guide gap can. To reduce the installation space and for a safe airbag deployment it is preferred if the storage space of the folded airbag on the of a footwell remote from the gas distributor is arranged. The folded Airbag is here between the elongated gas distributor and one Housing interior wall stowed. In this case, preferably the single-layer fabric layer of the airbag on the footwell be attached facing side of the gas distributor.
Konstruktiv bevorzugt ist es, wenn das Modulgehäuse zweiteilig aus einem hochbauenden Gehäuseteil für den Stauraum und einem flachbauenden Gehäuseteil für den Führungsspalt ausgebildet ist. Das hochbauende Gehäuseteil kann dabei in einem vom Fußraum entfernten, bauraumgünstigen Bereich angeordnet sein. Bei Aktivierung des Airbagmoduls wird der im hochbauenden Gehäuseteil untergebrachte Airbag durch den Führungsspalt aus dem Modulgehäuse gezogen. Der Führungsspalt ist im deaktivierten Zustand von einem Deckel verschlossen.constructive it is preferred if the module housing in two parts of a high-building housing part for the Storage space and a flat housing part is designed for the guide gap. The high-build housing part can do it in one of the footwell distant, space-saving area be arranged. When the airbag module is activated, it will be in high building housing part housed airbag pulled through the guide gap from the module housing. The guide gap is closed in the deactivated state by a lid.
Für eine kompakte Ausbildung des Airbagmoduls ist es von Vorteil, wenn der Gasgenerator zusammen mit dem Airbag im Stauraum des Gehäuses angeordnet ist. Bei der oben erwähnten zweiteiligen Ausführung des Modulgehäuses mit einem hochbauenden und einem flachbauenden Gehäuseteil kann daher der Gasgenerator zusammen mit dem gefalteten Airbag im hochbauenden Gehäuseteil des Airbagmoduls angeordnet sein.For a compact design of the airbag module, it is advantageous if the gas generator is arranged together with the airbag in the storage space of the housing. In the above-mentioned two-part design of the module housing with a building up and a flat housing part can Therefore, the gas generator may be arranged together with the folded airbag in the high-building housing part of the airbag module.
Der Gasverteiler des Airbagmoduls kann sich für eine Ausrichtung der Airbagentfaltung in eine bestimmte Richtung lanzenförmig in den Airbag hinein erstrecken, der mit einer Gewebelage um die stirnseitige Gasauslassöffnung des Gasverteilers geführt sein kann. Er kann zumindest einen Gaskanal aufweisen, der sich vom Gasgenerator in Richtung des Insassenraums erstreckt. Dabei kann der Gaskanal stirnseitig in ein Gasverteilerrohr münden, in dem auch die zumindest eine Gasausblasöffnung ausgebildet ist.Of the Gas distributor of the airbag module may be for an orientation of the airbag deployment lance-shaped into the airbag in a certain direction, with a fabric layer around the frontal gas outlet of the Gas distributor led can be. He can have at least one gas channel, which is extends from the gas generator in the direction of the passenger compartment. there the gas channel can open into a gas distribution pipe at the front, in which is also formed at least one Gasausblasöffnung.
Der Führungsspalt des Modulgehäuses kann wie erwähnt stirnseitig durch einen Deckel begrenzt sein, der als ein Designelement in der Instrumententafel integrierbar ist. Der Deckel kann dabei derart schwenkbar angelenkt sein, dass er zu einer vom Fußraum abgewandten Seite nach oben öffnet. Auf diese Weise wird eine zielgerichtete Entfaltung des Airbags nach oben unterstützt.Of the guide gap of the module housing can as mentioned bounded on the front by a lid, which serves as a design element can be integrated in the instrument panel. The lid can do this pivoted so hinged that it faces away from the footwell Side up opens. In this way, a targeted deployment of the airbag supported upwards.
Um zu vermeiden, dass die stirnseitig um den Gasverteiler geführte Gewebelage des Airbags bei Airbag-Aktivierung reißt, kann diese Gewebelage mit einer zusätzlichen Verstärkungslage verstärkt sein.Around To avoid that the front side around the gas distributor led fabric layer the airbag ruptures during airbag activation, this fabric layer can with an additional one reinforcing layer be strengthened.
In einem Verfahren zur Herstellung eines Airbagmoduls kann das Gehäuse des Airbagmoduls eine Mehrzahl von Gehäuseteilen aufweisen, die jeweils über ein Filmgelenk einstückig und materialeinheitlich miteinander verbunden sind. Die Funktionselemente des Airbagmoduls werden somit in eines dieser Gehäuseteile eingesetzt. Anschließend wird das Modulgehäuse durch ein Zusammenklappen der Gehäuseteile geschlossen. Zur Bereitstellung eines im Querschnitt geschlossenen Gehäuses können die Endseiten des Gehäuses jeweils über Schnapp- oder Rastelementen verbunden sein, die im geschlossenen Zustand gleichzeitig Sollbruchstellen zur Öffnung eines Gehäusedeckels bilden.In a method for producing an airbag module, the housing of the Airbag module having a plurality of housing parts, each having a Film joint in one piece and are connected to each other in the same material. The functional elements of the airbag module are thus in one of these housing parts used. Subsequently becomes the module housing closed by folding the housing parts. To provide of a housing closed in cross-section, the end sides of the housing can each be latched over or latching elements connected in the closed state at the same time predetermined breaking points for opening a housing cover form.
