Abstract
Description
Die vorliegende Erfindung betrifft einen Fahrzeugsitz mit integriertem Airbag-Modul gemäß dem Oberbegriff des Anspruchs 1.The The present invention relates to a vehicle seat with integrated Airbag module according to the preamble of claim 1.
In Kraftfahrzeugsitze eingebaute Airbags gehören heute zur Standardausrüstung von Kraftfahrzeugen. In aller Regel sind sie als sogenannte Seiten-Airbags in die Rückenlehne des Fahrzeugsitzes integriert, wobei dafür Sorge zu tragen ist, dass sich der Airbag im Bedarfsfall ungehindert aus der Rückenlehne heraus in die gewünschte Richtung entfalten kann. Dazu ist eine entsprechende Austrittsöffnung für den Airbag in der Rückenlehne erforderlich, die den ästhetischen Gesamteindruck des Sitzes stört. Es gibt daher verschiedene Lösungen, deren Ziel es ist, Optik und Funktionalität verträglich miteinander zu verbinden.In Motor vehicle seats built-in airbags are now standard equipment of Motor vehicles. As a rule, they are called so-called side airbags in the backrest integrated vehicle seat, taking care that If necessary, the airbag unhindered from the backrest out into the desired one Can develop direction. For this purpose, a corresponding outlet opening for the airbag in the backrest necessary that the aesthetic Overall impression of the seat disturbs. There are therefore different solutions whose aim is to combine optics and functionality in a compatible way.
Eine
häufig
zu findende Lösung,
zu der auch die vorliegende Erfindung zu zählen ist, besteht darin, den
Austritt mit dem Bezugsstoff der Polsterung zu überziehen (EP 07 51 047 A1,
Ein Airbag-Modul besteht aus einem Gehäuse, welches einen Gasgenerator und den Airbag beherbergt. Das Gehäuse weist eine Gehäuseschale aus Hartplastik auf, die an der Tragstruktur des Sitzes befestigt ist, sowie einen sie verschließenden Deckel. Überwiegend sind diese Deckel, wie auch die Gehäuseschale, als Spritzgussteile aus Hartplastik gefertigt. Derartige Modulgehäuse haben den Nachteil, dass sowohl für die Gehäuseschale, als auch für den Deckel Spritzgussformen zur Verfügung stehen müssen. Das erhöht die Teile- und Werkzeugkosten. Nachteilig ist auch das relativ hohe Gewicht des als Hartschale ausgebildeten Deckels.One Airbag module consists of a housing containing a gas generator and the airbag is housed. The housing has a housing shell Hard plastic, which is attached to the supporting structure of the seat, as well as a closing it Cover. Mostly These covers, as well as the housing shell, as injection molded parts made of hard plastic. Such module housing have the disadvantage that as well as the housing shell, as well as for the Lid injection molds available have to stand. That increases the parts and tool costs. Another disadvantage is the relatively high Weight of the designed as a hard shell lid.
Neben
den oben beschriebenen Airbag-Modulen mit „Hartdeckeln" sind auch Airbag-Module
mit „Softdeckeln" bekannt (
Mit diesen bekannten Airbag-Modulen mit Softabdeckungen werden die oben genannten Nachteile von Modulen mit Hartdeckeln beseitigt.With These known airbag modules with soft covers are the above mentioned disadvantages of modules with hard covers eliminated.
Aufgabe der vorliegenden Erfindung ist es, einen weiteren Fahrzeugsitz mit einem integriertem Airbag-Modul zur Verfügung zu stellen, welches eine Softabdeckung aufweist.task The present invention is to provide a further vehicle seat an integrated airbag module to provide, which is a soft cover having.
Erfindungsgemäß wird diese Aufgabe mit einem Fahrzeugsitz gelöst, der die Merkmale des Anspruchs 1 aufweist.According to the invention this Task solved with a vehicle seat, the characteristics of the claim 1 has.
Demnach ist die Abdeckung der Gehäuseschale des Airbag-Moduls ein filmartiges Flächengebilde, d. h., die Abdeckung ist im Vergleich zur Gehäuseschale dünnhäutig ausgeführt. Als Material für die Abdeckung kommt beispielsweise Vlies, Gewebe, eine Metallfolie oder eine Kunststofffolie in Frage. Die Abdeckung ist einstückig ausgeführt und am Rand der Gehäuseschale umlaufend befestigt. Die Verbindung zwischen der Abdeckung und der Gehäuseschale kann durch Vibrationsschweißen, Ultraschallschweißen, durch Kleben oder aber über einen Mikroklettverschluss realisiert werden. Obwohl die Abdeckung relativ dünnwandig ausgeführt ist, kann durch eine entsprechende Materialschwächung des Flächengebildes bzw. durch eine entsprechende Schwächung der Verbindung zwischen dem Flächengebilde und der Gehäuseschale eine bevorzugte Austrittsrichtung für den sich entfaltenden Airbag festgelegt werden.Therefore is the cover of the housing shell of the airbag module a film-like sheet, d. h., The cover is designed thin-skinned compared to the housing shell. As material for the cover comes for example fleece, fabric, a metal foil or a plastic film in question. The cover is made in one piece and on the edge of the housing shell attached all around. The connection between the cover and the shell can by vibration welding, Ultrasonic welding, by gluing or over a micro Velcro fastener can be realized. Although the cover relatively thin-walled accomplished is, by a corresponding material weakening of the fabric or by a corresponding weakening of the connection between the fabric and the housing shell set a preferred exit direction for the unfolding airbag become.
Das filmartige Flächengebilde bringt eine große Gewichtsersparnis und ist als Stanzteil bzw. Ausschnittteil kostengünstig herstellbar.The film-like fabrics brings a big one Weight savings and is inexpensive to produce as a stamped part or cut-out.
In einer vorteilhaften Ausführungsform der Erfindung ist die Gehäuseschale mit einem umlaufenden flanschartigen Rand versehen, der die Befestigung des filmartigen Flächengebildes erleichtert.In an advantageous embodiment The invention is the housing shell provided with a circumferential flange-like edge, the attachment of the film-like sheet facilitated.
Die Erfindung wird nachstehend anhand eines Ausführungsbeispiels näher erläutert. In der dazu gehörigen Zeichnung zeigt:The Invention will be explained in more detail with reference to an embodiment. In the corresponding one Drawing shows:
