Abstract

The application relates to a cover for an inflatable gas bag which is arranged in a vehicle, is used to protect the occupants and has a layer of foamed plastic or the like which is provided with a weakened predetermined breaking line. In order to ensure perfect operation when this foamed plastic layer is covered by a film, and at the same time to achieve a stylistic freedom to a substantial extent, provision is made for the plastic layer to be covered by a multi-part film on its outside facing the occupant of the vehicle, which film has a welded seam along the predetermined breaking line, with the strength of the said seam being less than the resistance to tearing of the film.

Description

Abdeckung für ein aufblasbares GaskissenCover for an inflatable gas cushion

Die Erfindung betrifft eine Abdeckung für ein in einem Fahrzeug angeordnetes, dem Schutz der Insassen dienendes aufblasbares Gaskissen, die eine mit einer geschwächten Sollbruchlinie ausgestattete geschäumte Kunststoffschicht aufweist.The invention relates to a cover for a arranged in a vehicle, Inflatable gas pillows that protect the occupants, one with a weakened one Has a predetermined breaking line equipped foamed plastic layer.

Eine derartige Abdeckung ist bereits der DE-OS 31 16 538 als bekannt zu entnehmen.Such a cover is already known from DE-OS 31 16 538 refer to.

Der vorliegenden Erfindung lag die Aufgabe zugrunde, einen einwandfreien Öffnungsvorgang der Abdeckung auch dann sicherzustellen, wenn die Oberfläche der Kunststoffschicht z.B. aus optischen Gründen mit einer Folie überzogen ist, die üblicherweise eine hohe Reißfestigkeit aufweist und bei der Sollbruchstellen durch Schwächung der Folie zu einer unbefriedigenden Dauerhaltbarkeit führen könnten.The present invention was based on the object of a flawless Ensure opening operation of the cover even if the surface of the Plastic layer, e.g. for optical reasons, is covered with a film that usually has a high tear strength and at the predetermined breaking points through Weakening of the film could lead to unsatisfactory durability.

definierten Gattung erfindungsgemäß dadurch gelöst daß die Kunststoffschicht auf ihrer dem Fahrzeuginsassen zugewandten Außenseite von einer mehrteilígen Folie abgedeckt ist, die entlang der Sollbruchlinie eine Schweißnaht aufweist, deren Festigkeit geringer als die Reißfestigkeit der Folie ist.defined genus according to the invention in that the plastic layer on the outside facing the vehicle occupant from a multi-part film is covered, which has a weld seam along the predetermined breaking line, the strength of which is less than the tear strength of the film.

Besonders vorteilhaft ist es dabei, wenn die Schweißnaht im Bereich von nach innen zur geschäumten Kunststoffschicht hin abgewinkelten Randbereichen der Folie liegt. In diesem Falle wird die Schweißnaht beim Entfalten des Gaskissens auf Schälung beansprucht, wodurch eine relativ geringe Festigkeit der Schweißnaht, die einer Funktion als Sollbruchlinie entgegenkommt, erreichbar ist.It is particularly advantageous if the weld seam is in the area edge areas angled inwards towards the foamed plastic layer the slide lies. In this case, the weld seam is when the gas cushion is unfolded stressed to peeling, whereby a relatively low strength of the weld seam, which meets a function as a predetermined breaking line, can be achieved.

In weiterer Ausgestaltung der Erfindung ist vorgesehen, daß die Schweißnaht Folienteile unterschiedlicher Farbe, Oberflächenstruktur od. dgl. verbindet. Auf diese Weise können vorteilhaft optisch ansprechende Gestaltungen einer Armaturentafel od. dgl. erzielt werden.In a further embodiment of the invention it is provided that the weld seam Foil parts of different colors, surface structures or the like. Connects. on In this way, visually appealing designs of a dashboard can be advantageous or the like. Can be achieved.

Der Gegenstand der Erfindung soll im folgenden anhand eines in der Zeichnung dargestellten Ausfünrung8beispiels näher erläutert werden.The object of the invention is to be based on one in the Ausfünrung8beispiels shown in the drawing are explained in more detail.

In der Zeichnung zeigen Fig. 1 einen Blick auf eine Armaturentafel eines Kraftwagens mit einer beifahrerseitig im Bereich eines Handschuhkastens angeordneten Abdeckung für ein hier nicht sichtbares Gaskissen, und Fig. 2 einen Schnitt nach der Linie II - II in Fig. 1.In the drawing, FIG. 1 shows a view of an instrument panel of a motor vehicle with one arranged on the passenger side in the area of a glove box Cover for a gas cushion not visible here, and Fig. 2 a Section along the line II - II in FIG. 1.

Die in Fig. 1 der Zeichnung dargestellte Armaturentafel 1 weist beifahrerseitig eine integrierte Abdeckung 2 für ein dahinterliegendes, hier mischt sichtbares aufblasbares Gaskissen auf, das im Falle eines Unfalls dem Schutz des Beifahrers dient.The dashboard 1 shown in Fig. 1 of the drawing has the passenger side an integrated cover 2 for an underlying, here mixed, inflatable one Gas cushion, which serves to protect the passenger in the event of an accident.

Die Abdeckung 2 besteht aus einer geschäumten Kunststoffschicht 3, die auf ihrer Außenseite durch eine Folie 4 abgedeckt ist. Um ein Entfalten des nicht dargestellten Gaskissens zu ermöglichen, weist die Abdeckung 2 eine Sollbruchlinie 5 auf, deren Verlauf folgend die geschäumte Kunststoffschicht 3 mit einer Materialschwächung 6 versehen ist.The cover 2 consists of a foamed plastic layer 3, which is covered on its outside by a film 4. In order to develop the To enable the gas cushion (not shown), the cover 2 has a predetermined breaking line 5, the course of which follows the foamed plastic layer 3 with a material weakening 6 is provided.

Gleichfalls der Sollbruchlinie 5 folgend weist die zweiteilige Folie 4 eine Schwei(3naht 7 auf, die im Bereich von flanschartig nach innen abgewinkelten Randbereichen der Folie liegt, so daß die Schweißnaht 7 beim Aufreißen der Abdeckung 2 auf Schälung beansprucht wird.The two-part film also follows the predetermined breaking line 5 4 a weld (3seam 7, which is angled inwardly in the area of a flange Edge areas of the film lies so that the weld seam 7 when the cover is torn open 2 is claimed for peeling.

Die verschiedenen Teile der Folie können eine unterschiediiche Farbe, Oberflächenstruktur od. dgl. aufweisen, so dali für eine stilistisch ansprechende Gestaltung der Armaturentafel od. dgl. ein weiter Spielraum besteht.The different parts of the film can have a different color, Surface structure or the like, so dali for a stylistically appealing Design of the dashboard or the like. There is a wide scope.
