Abstract
Description
Die Erfindung betrifft ein Gassack-Modul nach dem Oberbegriff des Anspruchs 1.The invention relates to an airbag module according to the preamble of claim 1.
Die Anordnung von Gassack-Modulen in Kraftfahrzeugen ist fast immer von Platzmangel begleitet. Dies trifft in besonderem Maße auf Gassack-Module zu, die zum Einbau in die Rückenlehne eines Fahrzeugsitzes vorgesehen sind (sogenannte Seitenairbags). Insbesondere bei sportlich ausgelegten Fahrzeugen ist der vorhandene Einbauraum stark begrenzt.The arrangement of gas bag modules in motor vehicles is almost always accompanied by a lack of space. This hits particularly well towards gas bag modules that are to be installed in the backrest of a vehicle seat are provided (so-called side airbags). Especially when it comes to sports designed vehicles, the available installation space is very limited.
Gassack-Module bestehen grundsätzlich aus einer Gasgeneratoreinheit, einem Gassack und einer Gassackhülle, welche den Gassack im Ruhezustand umgibt. Für Gassack-Module, die zum Einbau in die Rückenlehne eines Fahrzeugs geeignet sind, gibt es verschiedene Arten von Gassackhüllen:Airbag modules basically consist of a gas generator unit, an airbag and an airbag cover, which surrounds the gas bag in the idle state. For gas bag modules that are to be installed in the backrest are suitable for a vehicle, there are different types of gas bag covers:
Beispielsweise aus der
Es sind weiterhin Gassackeinheiten bekannt, bei denen die Gassackhülle aus einem zwei Halbschalen aufweisenden Kunststoffelement besteht, wobei die beiden Halbschalen über ein Scharnier miteinander verbunden sind. Eine solche Gassackhülle hat den Vorteil, dass sie den Gassack im eingebauten Zustand sehr gut schützt, nachteilig ist auch hier, dass entweder relativ viel Einbauplatz benötigt wird, oder für jeden Lehnentyp eine spezielle Gassackhülle benötigt wird. Auch dies ist aufwendig , da man für jede Halbschalenform ein separates Spritzgusswerkzeug benötigt.There are still gas bag units known in which the gas bag envelope consists of a two half-shell plastic element, wherein the two half shells over a hinge are connected. Such an airbag cover has the advantage that the gas bag when installed is very good protects Another disadvantage is that either a relatively large amount of installation space needed will, or for a special gas bag cover is required for each backrest type. This is also complex , because one for each Half-shell mold requires a separate injection mold.
Hiervon ausgehend ist es Aufgabe der Erfindung ein Gassack-Modul zu schaffen, das wenig Einbauplatz benötigt, einen guten Schutz des Gassacks im eingebauten Zustand bietet und eine grosse Flexibilität hinsichtlich des zur Verfügung stehenden Einbauraums aufweist.Based on this, it is the task the invention of creating an airbag module that has little installation space needed provides good protection for the gas bag when installed and great flexibility regarding the available has standing installation space.
Diese Aufgabe wird durch ein Gassack-Modul mit den Merkmalen des Anspruchs 1 gelöst.This task is carried out by an airbag module solved with the features of claim 1.
Die Gassackhülle des Gassack-Moduls besteht aus zwei über einen Randbereich miteinander verbundenen Elementen, die zwischen sich einen Hohlraum ausbilden, in dem der Gassack aufgenommen ist. Erfindungsgemäß besteht das eine Element aus Kunststoff. Dieses Element kann relativ steif ausgeführt sein und weist im eingebauten Zustand nach außen, so dass die gewünschte Schutzwirkung erzielt wird. Dieses Element kann ein Spritzgussteil oder ein Zuschnitt aus einer Konststofffolie oder einer Kunststoffplatte sein. Das andere Element besteht aus einem flexiblen Gewebe, hat also keine fest vorgegebene Form. Dieses Element weist nach innen und kann sich der gegebenen Struktur bis zu einem gewissen Grad anpassen. Somit wird der vorhandene Einbauraum optimal genutzt, ohne für jede Geometrie des Einbauraums eine separate Spritzgussform für dieses Element der Gassackhülle herstellen zu müssen.The airbag cover of the airbag module is there out of two over an edge area connected elements that between form a cavity in which the gas bag is received. According to the invention the one element made of plastic. This element can be relatively stiff accomplished be and points in the installed state to the outside, so that the desired protective effect is achieved. This element can be an injection molded part or a blank be made of a plastic film or a plastic sheet. The other element consists of a flexible fabric, so it has none fixed form. This element points inwards and can adapt to the given structure to a certain extent. Thus, the available installation space is used optimally, without any geometry of the installation space to produce a separate injection mold for this element of the gas bag envelope have to.
In einer bevorzugten Ausführungsform nach Anspruch 2 sind die beiden Elemente in einem Scharnierbereich dauerhaft miteinander verbunden und der übrige Randbereich ist so ausgestaltet, dass sich die Gassackhülle dort bei Expansion des Gassacks öffnet.In a preferred embodiment according to claim 2, the two elements are in a hinge area permanently connected to each other and the remaining edge area is designed that the gas bag envelope opens there when the gas bag expands.
In einer alternativen Ausführungsform gemäß Anspruch 3 bleiben die beiden Elemente auch bei expandiertem Gassack entlang des gesamten Randbereichs miteinander verbunden. Hier weist eines der Elemente einen von einer in der Regel U-förmigen Sollbruchlinie umgebenen Bereich auf, aus dem der expandierende Gassack austritt.In an alternative embodiment according to claim 3 the two elements remain along even when the gas bag is expanded the entire edge area connected. Here one points of the elements is surrounded by a generally U-shaped predetermined breaking line Area from which the expanding gas bag emerges.
Weitere bevorzugte Ausführungsformen ergeben sich aus den Unteransprüchen sowie aus den nun mit Bezug auf die Figuren näher erläuterten Ausführungsbeispielen. Hierbei zeigen:Further preferred embodiments result from the subclaims and from the exemplary embodiments now explained in more detail with reference to the figures. Here show:
