The support piece is built from injection moulded plastics and the capture hoop may be braced in sections. In both of the work tool halves in the capture hoops length direction, the support pieces may formed as connected to an alternative cavity (5). The capture hoop in the lower tool half of the horizontal piece of the injection mould tool is fixed using a peg clip.

Description

Die Erfindung betrifft ein Herstellverfahren für ein Kunststoff-Trägerteil eines Fahrzeug-Airbagsystemes, an welchem ein Fangband, insbesondere für ein Airbag-Deckelteil, befestigt ist. Zum bekannten Stand der Technik wird bei­ spielshalber auf die DE 43 15 853 A1 verwiesen, in welcher eine Armaturen­ tafel für einen Personenkraftwagen mit einem Beifahrer-Airbag beschrieben ist und worin auch die der vorliegenden Erfindung zugrundeliegenden Bau­ teile, nämlich ein Trägerteil eines Airbag-Faches, welches ein Airbag-Deckel­ teil trägt, sowie das genannten Fang band gezeigt sind.The invention relates to a manufacturing method for a plastic carrier part Vehicle airbag system on which a tether, especially for a Airbag cover part is attached. The known prior art is at For game's sake, reference is made to DE 43 15 853 A1, in which a fitting described for a passenger car with a passenger airbag is and in which also the construction on which the present invention is based parts, namely a carrier part of an airbag compartment, which an airbag cover part carries, as well as the mentioned tether are shown.

Es bestehen verschiedene Möglichkeiten, das Fang band am Trägerteil zu befestigen, beispielsweise durch Verschrauben oder durch ein separates Befestigungselement anlog der oben genannten Schrift, jedoch ist dies rela­ tiv aufwendig. Eine demgegenüber einfachere und dennoch äußerst stabile Befestigung des Fangbandes am Trägerteil aufzuzeigen bzw. anzugeben, wie ein derartiger Verband aus Trägerteil und Fang band auf einfache Weise hergestellt werden kann, hat sich die vorliegende Erfindung zur Aufgabe ge­ stellt.There are various ways to catch the tether on the carrier part attach, for example by screwing or by a separate Fastening element analogous to the above-mentioned font, but this is rela tivly complex. In contrast, it is simpler and yet extremely stable To show or indicate attachment of the tether to the carrier part, such a bandage made of carrier part and tether in a simple manner  can be produced, the present invention has ge task poses.

Zur Lösung dieser Aufgabe ist vorgesehen, daß in ein Spritzgieß-Werkzeug das Fang band abwechselnd mit seiner Oberseite und Unterseite an einer Werkzeug-Formhälfte anliegend eingelegt wird, und daß das als Kunststoff- Spritzgußteil ausgebildete Trägerteil das Fang band abschnittsweise umgrei­ fend geformt wird.To solve this problem it is provided that in an injection molding tool the muzzle alternately tied to one side with its top and bottom Tool mold half is inserted, and that as a plastic Injection molded part formed carrier part, the catch tape in sections fend is formed.

Dies sowie die in den Unteransprüchen angegebenen vorteilhaften Weiter­ bildungen der Erfindung wird im folgenden anhand eines bevorzugten Aus­ führungsbeispiels näher beschrieben. Dabei ist in den beigefügten Prin­ zipskizzen in Fig. 1 eine Teil-Aufsicht auf das Trägerteil mit integriertem Fangband gezeigt, während in Fig. 2 dieser Trägerteil-Fangband-Verbund im Spritzgieß-Werkzeug dargestellt ist, und zwar entsprechend dem Schnitt A-A aus Fig. 1.This and the advantageous further developments of the invention specified in the subclaims are described in more detail below with reference to a preferred exemplary embodiment. Here, in the accompanying Prin zipskizzen in Fig. 1 partial plan view shown one on the support member with an integrated tether, whereas in Fig. 2 this support part-tether composite in the injection molding tool is shown, corresponding to the section AA in FIG. 1.

Das Trägerteil für ein Airbag-Deckelteil eines Fahrzeug-Airbagsystemes ist mit der Bezugsziffer 1 bezeichnet. An diesem Trägerteil 1 soll ein Fang band 2 auf einfache Weise absolut sicher befestigt werden. Hierzu wird das Trä­ gerteil 1 als Kunststoff-Spritzgußteil in einem Spritzgieß-Werkzeug 3 ge­ formt, das wie üblich zwei Formhälften aufweist, nämlich eine obere Form­ hälfte 3a sowie untere Formhälfte 3b. Die Herstellung des Trägerteil-Fang­ band-Verbandes läuft dabei derart ab, daß zunächst das Fangband 2 in die untere Formhälfte 3b des geöffneten Spritzgieß-Werkzeuges 3 eingelegt wird. Hierin ist das Fangband 2 durch mehrere Aufsteckstifte 4 fixiert. An­ schließend wird das Werkzeug 3 wie üblich geschlossen, wobei - wie er­ sichtlich - das Fangband 2 abwechselnd mit seiner Oberseite 2a und seiner Unterseite 2b an einer Werkzeug-Formhälfte 3a bzw. 3b anliegt. Hierzu wei­ sen die beiden Werkzeug-Formhälften 3a, 3b in Fangband-Längsrichtung abwechselnd miteinander in Verbindung stehende Hohlräume 5 auf. An­ schließend wird das Kunststoff-Material für das Trägerteil 1 in das Spritz­ gieß-Werkzeug 3 bzw. in die Hohlräume 5 zwischen der oberen Formhälfte 3a und der unteren Formhälfte 3b eingebracht. Nach Aushärten der Kunst­ stoffmasse kann der Trägerteil-Fangband-Verband dem dann geöffneten Spritzgieß-Werkzeug 3 entnommen werden.The carrier part for an airbag cover part of a vehicle airbag system is designated by the reference number 1 . On this carrier part 1 , a tether 2 is to be fastened absolutely securely in a simple manner. For this purpose, the Trä gerteil 1 as a plastic injection molded part in an injection mold 3 ge forms, which, as usual, has two mold halves, namely an upper mold half 3 a and lower mold half 3 b. The manufacture of the carrier part-catch band association runs in such a way that first the tether 2 is inserted into the lower mold half 3 b of the opened injection molding tool 3 . Herein, the tether 2 is fixed by a plurality of pins 4 . At closing the tool 3 is closed as usual, whereby - as he can see - the tether 2 alternately bears with its top 2 a and its bottom 2 b on a mold half 3 a or 3 b. For this purpose, the two tool mold halves 3 a, 3 b alternately have interconnected cavities 5 in the longitudinal direction of the tether. At closing the plastic material for the carrier part 1 is introduced into the injection molding tool 3 or into the cavities 5 between the upper mold half 3 a and the lower mold half 3 b. After the plastic material has hardened, the carrier part tether bandage can be removed from the then opened injection molding tool 3 .

Durch die beschriebene Gestaltung der Werkzeug-Formhälften 3a, 3b ergibt sich die dargestellte Gestalt des Trägerteiles 1, in welche das Fangband 2 sicher und absolut fest integriert ist. Das Fangband 2 ist nämlich quasi in das Trägerteil 1 eingefädelt bzw. das Trägerteil 1 umgreift das Fangband 2 ab­ schnittsweise. Im ersten Abschnitt l befindet sich das Fangband 2 auf der Unterseite des Trägerteiles 1, durchdringt dieses dann im zweiten Abschnitt II, gelangt im Abschnitt III an die Oberseite des Trägerteiles 1, um im Ab­ schnitt IV das Trägerteil 1 wieder zu durchdringen und im Abschnitt V, der dem Abschnitt I entspricht, wieder auf der Unterseite des Trägerteiles 1 um­ griffen zu werden. Hierdurch ergibt sich eine innige Verbindung zwischen Fangband 2 und Trägerteil 1, welche auf die beschriebene Weise äußerst einfach hergestellt werden kann.The described design of the mold halves 3 a, 3 b results in the illustrated shape of the carrier part 1 , in which the tether 2 is securely and absolutely firmly integrated. The tether 2 is quasi threaded into the carrier part 1 or the carrier part 1 engages around the tether 2 from sections. In the first section l is the limiting strap 2 on the underside of the support member 1, then passes through this in the second section II, reaches the section III to the upper surface of the support part 1, to cut in the Ab IV, the carrier part 1 penetrate again and the section V , which corresponds to section I, again to be gripped on the underside of the carrier part 1 . This results in an intimate connection between the tether 2 and the carrier part 1 , which can be produced extremely simply in the manner described.

Das Spritzgieß-Werkzeug 3 bzw. die Spritzgieß-Maschine weist eine sog. vertikale Schließe auf, d. h. es handelt sich um ein horizontal geteiltes Spritzgieß-Werkzeug 3 mit einer oberen Formhälfte 3a sowie einer unteren Formhälfte 3b. Hierdurch ist sichergestellt, daß das Fangband 2 einfach auf die untere Formhälfte 3b aufgelegt werden kann und hierbei nicht von dieser Formhälfte 3b abfallen kann. Damit das Fangband 2b nicht in die Hohlräume 5 der unteren Formhälfte 3b hineinrutscht, ist das Fangband 2 zusätzlich durch die Aufsteckstifte 4 fixiert. Die Spritzgieß-Maschine kann dabei eine Werkzeug-Dreheinheit mit mehreren unteren Formhälften 3b aufweisen, so daß ein Werker in eine im Moment offene Formhälfte 3b ein Fangband 2 einlegen kann, solange in einer anderen unteren Formhälfte 3b, die mit einer oberen Formhälfte 3a ein geschlossenes Werkzeug 3 bildet, das Trägerteil 1 durch Kunststoff-Spritzgießen geformt wird. Dabei wird wie erläutert insbesondere mit Hilfe der speziellen Werkzeug-Geometrie das Fangband 2 beim Spritzgießprozeß so umspritzt, daß es von der Thermoplastmatrix des Trägerteiles 1 umschlossen und gegen Herausziehen aus demselben gesi­ chert ist. Dabei kann das Fang band 2 an jeder gewünschten Stelle aus dem Trägerteil 1 herausgeführt sein, es ist nicht erforderlich, diese Stelle - wie gezeigt - in die Trennebene des Werkzeuges 3 zu legen. Daneben können selbstverständlich auch noch eine Vielzahl weiterer Details durchaus abwei­ chend vom gezeigten Ausführungsbeispiel gestaltet sein, ohne den Inhalt der Patentansprüche zu verlassen. Stets ergibt sich ein äußerst einfaches Herstellverfahren, da keine Vormontage und nur lediglich geringe Hand­ lingsumfänge erforderlich sind, wobei gleichzeitig die Stabilität des Träger­ teil-Fangband-Verbandes gegen Herausreissen des Fangbandes 2 aus dem Trägerteil 1 extrem hoch ist.The injection molding tool 3 or the injection molding machine has a so-called vertical clasp, ie it is a horizontally divided injection molding tool 3 with an upper mold half 3 a and a lower mold half 3 b. This ensures that the tether 2 can simply be placed on the lower mold half 3 b and cannot fall off this mold half 3 b. So that the tether 2 b does not slip into the cavities 5 of the lower mold half 3 b, the tether 2 is additionally fixed by the push-on pins 4 . The injection molding machine can have a tool rotating unit with a plurality of lower mold halves 3 b, so that a worker in an open at the moment mold half 3 b a tether 2 can engage, while in another lower mold half 3 b, the top with a mold half 3 a forms a closed tool 3 , the carrier part 1 is molded by plastic injection molding. In this case, as will be explained in particular by means of special tool geometry, the tether 2 during injection molding so encapsulated that it is enclosed by the thermoplastic matrix of the support part 1 and gesi chert against withdrawal therefrom. The tether 2 can be guided out of the carrier part 1 at any desired point, it is not necessary to place this point - as shown - in the parting plane of the tool 3 . In addition, of course, a variety of other details can be designed deviating from the embodiment shown without departing from the content of the claims. There is always an extremely simple manufacturing process, since no preassembly and only a small amount of handling are required, and at the same time the stability of the carrier part-tether bandage against tearing out of the tether 2 from the carrier part 1 is extremely high.
