Description

Die Erfindung betrifft eine Steuergerät für einen Airbag gemäß Oberbegriff von Patentanspruch 1.The invention relates to a control device for an airbag according to the preamble of claim 1.

Ein bekanntes Steuergerät (WO 91/11745) weist ein Gehäuse auf, in dem eine Leiterplatte befestigt ist. Auf der Lei­ terplatte ist eine Schaltung mit ihren elektrischen Bauele­ menten angeordnet. Ein Steckerteil ist mit der Leiterplatte verlötet.A known control device (WO 91/11745) has a housing in which a circuit board is attached. On the lei terplatte is a circuit with its electrical components elements arranged. A plug part is with the circuit board soldered.

Ein solches Steuergerät hat den Nachteil, daß die Verbin­ dungswege zwischen den einzelnen Bauelementen und auch zur Fahrzeugkarosserie recht weit sind, da die Bauelemente auf die "zweidimensionale" Leiterplatte gelötet sind.Such a control device has the disadvantage that the connection paths between the individual components and also for Vehicle body are quite wide because the components are on the "two-dimensional" circuit board are soldered.

Der Erfindung liegt das Problem zugrunde, ein Steuergerät für einen Airbag zu schaffen, das kompakt aufgebaut ist, bei dem die elektrischen Verbindungen zwischen den Bauele­ menten kurz sind und das störsicher ist.The invention is based on the problem of a control unit for an airbag that is compact, where the electrical connections between the components elements are short and that is interference-proof.

Das Problem wird durch die Merkmale des Patentanspruchs 1 gelöst.The problem is solved by the features of claim 1 solved.

Bei dem Steuergerät wird eine "dreidimensionale" Leiter­ platte verwendet, deren Herstellung bereits bekannt ist ("Integration mit SIL-Technik", Siemens-Zeitschrift Spe­ cial, FuE, Herbst 1992, S. 4-9). Solche Leiterplatten sind der Fachwelt auch unter der Bezeichnung MID-Leiterplatten (Molded Interconnect Device) ein Begriff.The control unit uses a "three-dimensional" ladder plate used, the manufacture of which is already known ("Integration with SIL technology", Siemens magazine Spe cial, R&D, autumn 1992, pp. 4-9). Such circuit boards are to the professional world also under the name MID printed circuit boards (Molded Interconnect Device) a term.

Für das Airbag-Steuergerät ist die Leiterplatte wannenför­ mig ausgebildet und dient zugleich als Gehäuse. Die Bauele­ mente sind an seiner Innenwand angelötet. Die Außenwand ist ganzflächig mit einer Metallschicht zur elektromagnetischen Abschirmung versehen. Ein Deckel verschließt das Gehäuse.The circuit board for the airbag control unit is trough-shaped mig trained and also serves as a housing. The Bauele elements are soldered to its inner wall. The outside wall is  all over with a metal layer for electromagnetic Provide shielding. A cover closes the housing.

Vorteilhafte Ausgestaltungen sind in den Unteransprüchen gekennzeichnet. Dadurch daß das Gehäuse aus Kunststoff hergestellt ist, werden kleine Erschütterungen gedämpft und führen nicht zu einer unbeabsichtigten Auslösung des Air­ bags. Kunststoff und seine Metallschichten können voneinan­ der getrennt und damit wiederverwendet werden.Advantageous embodiments are in the subclaims featured. Characterized in that the housing made of plastic small vibrations are damped and do not cause the Air to trigger unintentionally bags. Plastic and its metal layers can coexist which can be separated and reused.

Durch ein Spritzgußteil können beliebige Raumformen herge­ stellt werden, so daß alle elektrischen Verbindungswege zwischen den Bauelementen sehr kurz sind. Außerdem kann der Gehäuseinnenraum optimal ausgenutzt werden, so daß die Bauform des Steuergeräts klein wird, um es beispielsweise in ein Lenkrad eines Kraftfahrzeugs zu montieren.Any shape of space can be achieved using an injection molded part poses so that all electrical connection paths between the components are very short. In addition, the Housing interior can be optimally used so that the Design of the control unit becomes small, for example to mount in a steering wheel of a motor vehicle.

Ein Steckerteil und Befestigungselemente können einstückig mit dem Gehäuse hergestellt werden. Somit entfallen Befe­ stigungsmittel und zusätzliche elektrische Verbindungen. Die Teilezahl und der damit verbundene Aufwand bei der Montage und Lagerung reduziert sich dadurch.A plug part and fastening elements can be in one piece be made with the housing. Thus there are no bees cleaning agents and additional electrical connections. The number of parts and the associated effort at This reduces assembly and storage.

Durch zusätzliche Zwischenwände mit Leiterbahnen kann die Packungsdichte der Schaltung erhöht werden.With additional partitions with conductor tracks, the Packing density of the circuit can be increased.

Ein Ausführungsbeispiel der Erfindung ist nachfolgend unter Bezugnahme auf die schematische Zeichnung näher erläutert. Es zeigtAn embodiment of the invention is below Reference to the schematic drawing explained in more detail. It shows

Fig. 1 eine Draufsicht auf das erfindungsgemäße Steuerge­ rät und Fig. 1 advises a top view of the Steuerge invention and

Fig. 2 einen Schnitt durch das Steuergerät entlang der Linie II-II in Fig. 1. FIG. 2 shows a section through the control device along the line II-II in FIG. 1.

Ein Steuergerät für ein Airbag eines Kraftfahrzeugs weist ein wannenförmiges Gehäuse 1 (Fig. 1) auf, in dem eine Schaltung zum Detektieren eines Aufpralls oder Crashs un­ tergebracht ist. Das Gehäuse 1 ist durch einen Metall-Dec­ kel 2 (Fig. 2), der mit dem Gehäuse 1 verschraubt ist, dicht verschlossen.A control unit for an airbag of a motor vehicle has a trough-shaped housing 1 ( FIG. 1) in which a circuit for detecting an impact or crash is accommodated. The housing 1 is tightly sealed by a metal Dec 2 ( Fig. 2) which is screwed to the housing 1 .

Das Gehäuse 1 ist mit Hilfe der SIL-Technologie (Spritzgußteil mit integrierten Leiterzügen) hergestellt. Dabei wird Kunststoff, z. B. ein hochwertiger Thermoplast, zum Spritzgießen des dreidimensionalen, d. h. räumlich ge­ formten Gehäuses 1 verwendet. Ein Metallisierungsverfahren sorgt für eine gut haftende Metallschicht 3 sowohl auf der Außen- als auch auf der Innenwand. Anschließend wird die Metallschicht 3 auf der Innenwand strukturiert, d. h. mit Hilfe eines Lasers werden nicht dargestellte Leiterbahnen und Massepotentialflächen erzeugt.The housing 1 is manufactured with the help of SIL technology (injection molded part with integrated conductor tracks). Plastic, e.g. B. a high quality thermoplastic, used for injection molding the three-dimensional, ie spatially shaped housing 1 ge. A metallization process ensures that the metal layer 3 adheres well to both the outer and the inner wall. The metal layer 3 is then structured on the inner wall, ie conductor tracks and ground potential surfaces (not shown) are generated with the aid of a laser.

Der Kunststoff des Gehäuses 1 tritt an die Stelle des Die­ lektrikums oder der elektrische Isolierung der herkömmli­ chen, zweidimensionalen Leiterplatte. Außerdem hat der Kunststoff den Vorteil, daß Crash-Sensoren 4, die einen Aufprall detektieren sollen, direkt an dem Gehäuse 1 befe­ stigt werden können. Durch den thermoplastischen Kunststoff werden die Sensoren 4 bereits bei Qualitätsprüfungstests, wie Falltest, geschützt.The plastic of the housing 1 takes the place of the dielectric or electrical insulation of the conventional two-dimensional circuit board. In addition, the plastic has the advantage that crash sensors 4 , which are intended to detect an impact, can be attached directly to the housing 1 . The thermoplastic material protects the sensors 4 during quality inspection tests such as drop tests.

Somit hat das Gehäuse 1 einerseits eine Gehäuseträgerfunk­ tion und andererseits übernimmt es die elektrischen Eigen­ schaften einer herkömmlichen "zweidimensionalen Leiter­ platte". Das Gehäuse 1 kann auch als "dreidimensionale Leiterplatte" bezeichnet werden.Thus, the housing 1 on the one hand a housing carrier function and on the other hand it takes over the electrical properties of a conventional "two-dimensional circuit board". The housing 1 can also be referred to as a "three-dimensional circuit board".

Ein Steckerteil 5 ist einstückig mit dem Gehäuse 1 herge­ stellt. Seine Steckerstifte 6 können in dem Kunststoff eingebettet sein. Nach dem Metallisieren des Gehäuses 1 und Strukturieren der Metallschicht sind die Steckerstifte 6 elektrisch mit der Schaltung verbunden. Die Steckerstifte 6 brauchen dann nicht mehr mit den Leiterbahnen verlötet zu werden. Die Steckerstifte 6 können aber auch nachträglich durch in einem Raster angeordnete Löcher im Gehäuse 1 ge­ steckt und durch Löten mit den Leiterbahnen elektrisch verbunden werden.A plug part 5 is in one piece with the housing 1 Herge provides. Its connector pins 6 can be embedded in the plastic. After metallizing the housing 1 and structuring the metal layer, the connector pins 6 are electrically connected to the circuit. The connector pins 6 then no longer need to be soldered to the conductor tracks. The connector pins 6 can also be inserted subsequently through holes arranged in a grid in the housing 1 and be electrically connected to the conductor tracks by soldering.

Halterungen 8 und Befestigungselemente 9 sind ebenfalls einstückig mit dem Gehäuse 1 hergestellt. Somit entfallen sämtliche nachträgliche Befestigungsvorgänge innerhalb des Gehäuses 1. Damit das Steuergerät an seinem Einsatzort durch Schrauben befestigt werden kann, weisen die Befesti­ gungselemente 9 Bohrungen 10 auf. Um diese Bohrungen 10 sind umlaufend Durchgangsbohrungen 11, die mit Metall, beispielsweise Hohlnieten ausgefüllt sind, angeordnet. Dadurch werden die Befestigungselemente 9 stabilisiert und gestützt, wenn beim Befestigen des Steuergeräts mit Schrau­ ben die Befestigungselemente 9 einem hohen Preßdruck ausge­ setzt werden. Der Kunststoff würde ansonsten ein Fließver­ halten aufweisen.Brackets 8 and fasteners 9 are also made in one piece with the housing 1 . All subsequent fastening processes within the housing 1 are thus omitted. So that the control unit can be fastened at its place of use by screws, the fastening supply elements 9 have bores 10 . Through-holes 11 , which are filled with metal, for example hollow rivets, are arranged all around these holes 10 . As a result, the fasteners 9 are stabilized and supported when the fasteners 9 are put out a high pressing pressure when attaching the control unit with screw ben. The plastic would otherwise have a flow behavior.

Die ganz flächig auf der Außenwand befindliche Metallschicht 3 ist im Betrieb des Steuergeräts mit Masse elektrisch verbunden und dient zusammen mit dem Deckel 2 zur EMV-Ab­ schirmung des Steuergeräts sowie zur Wärmeabfuhr. Der Dec­ kel 2 muß ferner das Gehäuse 1 staub- und/oder feuchtig­ keitsdicht verschließen. Hierzu kann der Rand des Gehäuses 1 auf unterschiedliche Weise ausgebildet sein, beispiels­ weise mit einer nicht dargestellten, umlaufenden Nut, die mit einer Dichtmasse gefüllt wird. Anschließend wird der Deckel 2 auf die Nut gesetzt und mit dem Gehäuse 1 ver­ schraubt.The very flat on the outer wall metal layer 3 is electrically connected to ground during operation of the control unit and is used together with the cover 2 for EMC shielding of the control unit and for heat dissipation. The Dec kel 2 must also close the housing 1 dust and / or moisture-tight. For this purpose, the edge of the housing 1 can be designed in different ways, for example with a circumferential groove, not shown, which is filled with a sealing compound. Then the lid 2 is placed on the groove and screwed to the housing 1 ver.

In der Schaltung können verschiedenste Bauelemente 12, wie diskrete Bauelemente, SMD-Bauelemente oder auch ungehäuste Halbleiterbauelemente verwendet werden. Die Bauelemente 12 können an den entsprechenden Halterungen 8 - bedingt durch die dreidimensionale Leiterplatte - in verschiedenen Ebenen befestigt und auf bekannte Weise mit den Leiterbahnen elek­ trisch verbunden werden.A wide variety of components 12 , such as discrete components, SMD components or unhoused semiconductor components, can be used in the circuit. The components 12 can be attached to the corresponding brackets 8 - due to the three-dimensional circuit board - in different planes and electrically connected to the conductor tracks in a known manner.

Durch die Möglichkeit, die Bauelemente 12 räumlich anzuord­ nen, werden kurze elektrische Verbindungswege erzielt, die weniger störanfällig sind. EMV-kritische Leiterbahnen kön­ nen zudem sehr kurz gehalten werden. Dadurch wird auch eine sehr kompakte Bauform erreicht mit einer hohen Packungs­ dichte der Schaltung.Due to the possibility of spatially arranging the components 12 , short electrical connection paths are achieved which are less susceptible to faults. EMC-critical traces can also be kept very short. This also results in a very compact design with a high packing density of the circuit.

Die Bauelemente 12 und Sensoren 4 sind in den Figuren der Übersichtlichkeit halber geschnitten dargestellt.The components 12 and sensors 4 are shown in section in the figures for the sake of clarity.

Das Gehäuse 1 kann auch mit mindestens einer beiderseitig Leiterbahnen tragenden, nicht dargestellten Zwischenwand ausgebildet sein. Diese ist dann einstückig mit dem Gehäuse 1 hergestellt. Dadurch wird das Gehäuse 1 in voneinander getrennte, wannenförmige Kammern geteilt ist, in denen verschieden Teile der Schaltung untergebracht werden kön­ nen, die sich gegenseitig nicht stören sollen.The housing 1 can also be formed with at least one intermediate wall, not shown, which carries conductor tracks on both sides. This is then made in one piece with the housing 1 . As a result, the housing 1 is divided into separate trough-shaped chambers in which different parts of the circuit can be accommodated, which should not interfere with one another.

Die Verwendung einer dreidimensionalen Leiterplatte bei einem Airbag-Steuergerät hat zudem den Vorteil, daß das Gehäuse 1 einfach recycelt werden kann. Bei einem ausge­ dienten Steuergerät können die elektrischen Bauelemente 12 und Sensoren 4 durch entsprechende Wärmebehandlung auf einfache Art und Weise vom Gehäuse 1 getrennt werden. Die Metallschichten und der Kunststoff sind trennbar und wie­ derverwertbar.The use of a three-dimensional circuit board in an airbag control unit also has the advantage that the housing 1 can be easily recycled. When a control device is used, the electrical components 12 and sensors 4 can be separated from the housing 1 in a simple manner by appropriate heat treatment. The metal layers and the plastic are separable and reusable.
