Abstract
Description
Die vorliegende Erfindung betrifft eine Airbaganordnung für Fahrzeuge gemäß dem Oberbegriff des Patentanspruches 1.The The present invention relates to an airbag assembly for vehicles according to the preamble of Claim 1.
Die meisten Fahrzeuge sind standardmäßig mit Lenkradairbags, Beifahrerairbags und teilweise auch mit Sitz-, Tür- und anderen Seitenairbags ausgestattet. Die Airbagmodule von Beifahrerairbags sind in die Instrumententafel integriert. Die Austrittsöffnung für den Beifahrerairbag ist bei vielen Fahrzeugen durch einen Airbagdeckel abgedeckt, der vom Fahrgastraum aus als separates Bauteil erkennbar ist. Ein solcher vom Fahrgastraum aus erkennbarer Airbagdeckel wird vor allem bei hochpreisigen Fahrzeugen aus Designgründen als störend empfunden. Bei modernen hochpreisigen Fahrzeugen ist der Airbagdeckel des Beifahrerairbags daher häufig „nahtlos" in die Instrumententafelabdeckung integriert. Die Dekorschicht der Instrumententafel erstreckt sich dabei nahtlos über die Austrittsöffnung des Airbags. Somit ist die Lage des Beifahrerairbags vom Fahrgastraum aus nicht ersichtlich. Um ein zuverlässiges und kontrolliertes Aufreißen der Instrumententafelabdeckung bei der Airbagauslösung sicherzustellen, muss die Airbagabdeckung üblicherweise an den Aufreißstellen geschwächt wer den, was bei jeder Fahrzeugneuentwicklung mit einem beträchtlichen Entwicklungsaufwand verbunden ist.The Most vehicles are standard with Steering wheel airbags, passenger airbags and sometimes also with seat, door and other Side airbags equipped. The airbag modules of passenger airbags are integrated into the instrument panel. The outlet opening for the front passenger airbag is covered in many vehicles by an airbag cover from the Passenger compartment is recognizable as a separate component. Such a From the passenger compartment recognizable airbag cover is especially at high-priced vehicles for design reasons as bothersome. In modern high-priced vehicles is the airbag cover of the passenger airbag therefore often "seamless" in the instrument panel cover integrated. The decorative layer of the instrument panel extends seamlessly over the outlet of the Airbags. Thus, the position of the passenger airbag from the passenger compartment from not apparent. For a reliable and controlled ripping of the Instrument panel cover to ensure the airbag deployment must the airbag cover usually at the breakpoints weakened who, what with every new vehicle development with a considerable Development effort is connected.
Aufgabe der Erfindung ist es, eine Airbaganordnung zu schaffen, die hinter einer aufreißbaren Verkleidung angeordnet ist und die eine hohe Funktionssicherheit aufweist.task The invention is to provide an airbag assembly which is behind a tearable disguise is arranged and has a high reliability.
Diese Aufgabe wird durch die Merkmale des Patentanspruches 1 gelöst. Vorteilhafte Ausgestaltungen und Weiterbildungen der Erfindung sind den Unteransprüchen zu entnehmen.These The object is solved by the features of claim 1. advantageous Refinements and developments of the invention are the dependent claims remove.
Die Erfindung geht von einer Airbaganordnung mit einem Airbagmodul aus, das hinter einer Fahrgastraumverkleidung angeordnet ist. Die Verkleidung ist aus mehreren Schichten aufgebaut. Sie weist eine Tragschicht auf, die aus einem Kunststoffmaterial im Spritzgussverfahren hergestellt ist. Die Tragschicht wiederum weist eine Ausnehmung auf, welche sich in einem „Austrittsbereich" befindet, der für den Austritt des Airbags in den Fahrgastraum hinein vorgesehen ist. Die Ausnehmung ist durch ein Deckelelement verschlossen, das einen umlaufenden seitlichen Rand aufweist. Die Verkleidung weist ferner eine Schaumschicht auf, die auf die Tragschicht und auf das Deckelelement aufgebracht ist. Auf die Schaumschicht wiederum ist eine Dekorschicht aufgebracht. Die Dekorschicht erstreckt sich nahtlos über den Austrittsbereich des Airbags. Somit ist vom Fahrgastraum aus die Lage des Austrittsbereichs bzw. die Lage der in der Tragschicht vorgesehenen Ausnehmung nicht zu erkennen. Bei einer Auslösung des Airbags reißen die Schaumschicht und die Dekorschicht auf und öffnen sich zum Fahrgastraum hin.The Invention is based on an airbag arrangement with an airbag module, which is arranged behind a passenger compartment lining. The costume is made up of several layers. It has a base course on, made of a plastic material by injection molding is. The support layer in turn has a recess, which is in an "exit area" that is for exit of the airbag is provided in the passenger compartment inside. The recess is closed by a lid member having a circumferential has lateral edge. The cladding further comprises a foam layer on, which is applied to the base layer and on the lid member is. In turn, a decorative layer is applied to the foam layer. The decorative layer extends seamlessly over the exit area of the Airbags. Thus, from the passenger compartment is the location of the exit area or the position of the recess provided in the support layer not to recognize. At a trip of the airbag tear the foam layer and the decorative layer on and open to the passenger compartment out.
Der Kern der Erfindung besteht darin, dass die Tragschicht unmittelbar an den Rand des Deckelelements angespritzt ist, wobei das Deckelelement ausschließlich aufgrund der Rauhigkeit der aneinander anliegenden Flächen des Deckelelements und des Tragteils an dem Tragteil fixiert ist. „Ausschließlich aufgrund der Rauhigkeit" ist in der folgenden Beschreibung und in den Patentansprüchen so zu verstehen, das zwischen dem Deckelelement und der Tragschicht auch ein Formschluss bestehen kann. Das Deckelelement und die Tragschicht können auch stoffschlüssig miteinander verbunden sein. Im Unterschied zu vielen bekannten Airbaganordnungen handelt es sich bei dem Deckelelement nicht um einen entlang seines Rands geschwächten integralen Bestandteil der Tragschicht, sondern um ein separates Bauteil.Of the Core of the invention is that the support layer directly is molded onto the edge of the lid member, wherein the lid member solely due the roughness of the abutting surfaces of the lid member and the Support member is fixed to the support member. "Exclusively due to the roughness" is in the following Description and in the claims to be understood as between the cover element and the support layer also have a positive connection can. The cover element and the support layer can also cohesively with each other be connected. In contrast to many known airbag arrangements is the lid member not one along its Rands weakened integral part of the base layer, but a separate component.
Das Deckelelement kann aus einem anderen Material hergestellt sein als die Tragschicht. Vorzugsweise ist es aus einem Material hergestellt, das eine geringere Dichte aufweist als die Tragschicht, wodurch sich die Verletzungsgefahr für die Fahrgäste beim Aufreißen des Airbags verringert. Das Deckelelement kann beispielsweise aus einem Polyurethanhartschaum oder aus einem expandiertem Polypropylen hergestellt sein. Das Tragteil kann aus einem thermoplastischen Werkstoff, z. B. aus Polypropylen, oder aus einem ABS-Kunststoff hergestellt sein. Bei der Herstellung der Airbagabdeckung wird das Deckelelement in ein Spritzgusswerkzeug eingelegt und mit dem Tragteilmaterial umspritzt. Vorzugsweise „liegt" das Tragteilmaterial ausschließlich an den seitlichen Rändern des Deckelelements an. Zwischen dem Deckelelement und dem Tragteil entsteht keine chemische Verbindung sondern eine rein mechanische Verbindung. Das Deckelelement ist also ausschließlich aufgrund der Rauhigkeit der aneinander anliegenden Flächen an dem Tragteil fixiert. Der „Rand" des Deckelelements stellt gleichzeitig die Aufreißlinie der Verkleidung dar.The Cover element may be made of a different material than the base course. Preferably, it is made of a material which has a lower density than the base layer, whereby the risk of injury for the passengers at the Rip of the airbag reduced. The lid member may for example a rigid polyurethane foam or an expanded polypropylene be prepared. The support member may be made of a thermoplastic Material, eg. B. of polypropylene, or of an ABS plastic be prepared. In the manufacture of the airbag cover is the Lid element inserted in an injection mold and with the support member material molded. Preferably, the support material is "lying" exclusively at the side edges of the lid member. Between the lid member and the support member does not create a chemical compound but a purely mechanical Connection. The cover element is therefore solely due to the roughness the adjoining surfaces fixed to the support part. The "edge" of the cover element At the same time, it represents the tear line the disguise dar.
