Description

Die Erfindung betrifft einen in einem Gehäuse angeordneten Schalter gemäß den Merkmalen des Oberbegriffes des Patentan­ spruches 1.The invention relates to a arranged in a housing Switch according to the features of the preamble of the patent saying 1.

Ein derartiger in einem Gehäuse angeordneter Schalter ist be­ reits bekannt (DE 81 03 264 U1), wobei das Gehäuse im Bereich seiner Einstecköffnung für eine Schloßzunge elektrische Kon­ taktfedern - vorzugsweise als Reed-Schalter ausgebildet - trägt, welche durch einen an der Schloßzunge befestigten Dauermagneten bei im Gurtschloßgehäuse verriegelter Schloßzunge schaltbar sind.Such a switch arranged in a housing is be already known (DE 81 03 264 U1), the housing in the area its insertion opening for a lock tongue electrical Kon clock springs - preferably designed as reed switches - carries, which by a permanent magnet attached to the lock tongue switchable when the tongue is locked in the buckle housing are.

Aufgabe der Erfindung ist es, einen gattungsgemäßen Schalter hinsichtlich seiner Kompaktheit und Funktionssicherheit sowie seiner einfachen Montierbarkeit weiterzubilden.The object of the invention is a generic switch with regard to its compactness and functional reliability as well to further develop its simple assembly.

Diese Aufgabe wird bei einem in einem Gehäuse angeordneten Schalter mit den Merkmalen des Anspruches 1 gelöst, wobei vor­ teilhafte Aus- und Weiterbildungen durch die Merkmale der Un­ teransprüche gekennzeichnet sind.This task is arranged in a housing Switch with the features of claim 1 solved, before partial education and training through the characteristics of the Un claims are marked.

Ein Ausführungsbeispiel der Erfindung ist in der Zeichnung dargestellt und wird im folgenden anhand eines Gurtschloß­ schalters näher beschrieben. Es zeigtAn embodiment of the invention is in the drawing shown and is shown below using a belt buckle described in more detail. It shows

Fig. 1 den in einem Gehäuse angeordneten Schalter und Fig. 1, the switch arranged in a housing and

Fig. 2 die im Gehäuse angeordneten zugehörigen Leiter­ bahnen der Schaltkreise. Fig. 2 arranged in the housing associated conductor tracks of the circuits.

In bekannter Weise ist das Gurtschloß an der Karosserie oder dem Fahrzeugsitz befestigt, hingegen die Schloßzunge am an der B-Säule aufrollbar angeordneten Gurt.In a known manner, the belt buckle is on the body or attached to the vehicle seat, while the lock tongue on the B-pillar arranged belt.

Am Gurtschloß oder in dieses integriert ist ein Gehäuse 1 mit Schalter(n) 2, welche als kompakte Einheit ausgebildet sind. Für eine multifunktionelle Kontaktschaltung ist das Gehäuse in etwa U-förmig ausgebildet und in beiden Schenkeln 1.1 und 1.2 sind Schalterteile angeordnet. So dient beispielsweise der im rechten Schenkel 1.1 angeordnete Schalterteil zur Ansteuerung einer Schaltung einer Gurtwarnung, des Gurttragekomforts, des Gurtbringers, des Gurtstraffers etc. und der im linken Schenkel 1.2 angeordnete Schalterteil zur Ansteuerung einer Schaltung des Airbags. An jedem Schenkel 1.1, 1.2 ist in Gehäuseführungen 3.1, 3.2 ein Schieber 4.1, 4.2 beweglich geführt, welcher in seiner einen Stellung aus der Gehäuseführung herausragt und in seiner anderen Stellung in die Gehäuseführung eintaucht. Im rechten Schenkel 1.1 ist der Schieber in seiner herausragenden Stellung dargestellt, welche die Schieber beispielsweise ein­ nehmen, wenn die Schloßzunge in das Gurtschloß gesteckt ist; im linken Schenkel 1.2 ist der Schieber in seiner eingetauchten Stellung dargestellt, welche die Schieber einnehmen, wenn die Schloßzunge nicht gesteckt ist. Mit den Schiebern 4.1, 4.2 fest verbunden sind Dauermagnete 5.1, 5.2, an welchen sich wiederum gehäuseseits abgestützte Federn 6.1, 6.2 anlegen, welche über die Dauermagnete die Schieber in ihre herausragende Stellung vorspannen. Des weiteren ist in jedem Schenkel 1.1, 1.2 ein Kontaktfederelement 7.1, 7.2 aus nichtmagnetischem Werkstoff gehäusefest eingespannt, wobei die Einspannstellen 1.1.1, 1.2.1 weit oberhalb der Stellung der Dauermagnete bei herausragender Stellung der Schieber liegen. Dies deshalb, um eine ausrei­ chende Feder-Länge der Kontaktfederelemente zu erzielen, welche an ihrem freien Ende eine ferromagnetische Masse 7.1.1, 7.2.1 - vorzugsweise als Reineisenteil - tragen. Diese Masse ist zum einen auf dem Kontaktfederelement so angeordnet, daß es dem Dauermagnet zugewandt liegt, und zum anderen erstreckt sich das Kontaktelement mit der Masse von seiner Einspannstelle so weit nach unten, daß bei herausragender Stellung des Schiebers das Magnetfeld des Dauermagneten keinen Einfluß auf die Masse hat, hingegen bei eingetauchter Stellung des Schiebers der Dauerma­ gnet in etwa der Masse gegenüber liegt und somit dessen Ma­ gnetfeld Einfluß auf die Masse ausübt und diese anziehen kann. Diese Konfigurationen sind im linken und rechten Schenkel dar­ gestellt. Selbstverständlich nehmen beide Schieber entweder die eine oder die andere Stellung ein, da beide stets gemeinsam und gleichsinnig bewegt werden.On the belt buckle or integrated therein is a housing 1 with switch (s) 2 , which are designed as a compact unit. For a multifunctional contact circuit, the housing is approximately U-shaped and switch parts are arranged in both legs 1.1 and 1.2 . Thus, for example, the switch part arranged in the right leg 1.1 serves to control a circuit of a belt warning, the belt wearing comfort, the belt feeder, the belt tensioner etc. and the switch part arranged in the left leg 1.2 serves to control a circuit of the airbag. On each leg 1.1 , 1.2 , a slide 4.1 , 4.2 is movably guided in housing guides 3.1 , 3.2 , which in one position protrudes from the housing guide and, in its other position, plunges into the housing guide. In the right leg 1.1 , the slider is shown in its outstanding position, which the slider take, for example, when the lock tongue is inserted into the buckle; in the left leg 1.2 , the slide is shown in its immersed position, which the slide occupies when the lock tongue is not inserted. Permanent magnets 5.1 , 5.2 are fixedly connected to the sliders 4.1 , 4.2 , on which in turn springs 6.1 , 6.2 supported on the housing side, which bias the slides into their outstanding position via the permanent magnets. Furthermore, a contact spring element 7.1 , 7.2 made of non-magnetic material is clamped fixed to the housing in each leg 1.1 , 1.2 , the clamping points 1.1.1 , 1.2.1 being far above the position of the permanent magnets when the slide is in an outstanding position. This is in order to achieve a sufficient spring length of the contact spring elements, which carry a ferromagnetic mass 7.1.1 , 7.2.1 at their free end - preferably as a pure iron part. This mass is arranged on the one hand on the contact spring element so that it faces the permanent magnet, and on the other hand the contact element extends with the mass from its clamping point so far down that the magnetic field of the permanent magnet has no influence on the outstanding position of the slide Mass has, however, when the slide is immersed, the permanent magnet is approximately opposite the mass and thus its magnetic field exerts influence on the mass and can attract it. These configurations are shown in the left and right leg. Of course, both sliders take either one or the other position, since both are always moved together and in the same direction.

Zwischen der Einspannstelle und der Masse trägt jedes Kontakt­ federelement des weiteren noch elektrische Kontakte 7.1.2, 7.1.3 bzw. 7.2.2, 7.2.3, welche mit gehäusefesten Kontaktele­ menten 8.1, 8.2 bzw. 8.3, 8.4 korrespondieren, wobei das Kon­ taktelement 8.4 beispielsweise nicht belegt ist.Between the clamping point and the mass, each contact spring element also carries electrical contacts 7.1.2 , 7.1.3 or 7.2.2 , 7.2.3 , which correspond to elements 8.1 , 8.2 or 8.3 , 8.4 fixed to the housing , the con Clock element 8.4 is not occupied, for example.

Hat nun beispielsweise der Fahrer seinen Gurt nicht angelegt, d. h., die Schloßzunge ist nicht in das Gurtschloß gesteckt, so drückt die im Gurtschloß angeordnete Halteplatte 9 die Schieber 4.1, 4.2 und mit diesen auch die Dauermagnete 5.1, 5.2 gegen die Kraft der Federn 6.1, 6.2 nach unten. Hierbei gelangt jede Masse 7.1.1, 7.2.1 in das Magnetfeld der Dauermagnete 5.1, 5.2 und werden von diesen angezogen. Hierbei wird die Kontaktpaa­ rung 7.1.3-8.1 geöffnet und die Kontaktpaarung 7.1.2-8.2 geschlossen, ebenso wird die Kontaktpaarung 7.2.2-8.3 geöff­ net und das Kontaktelement 7.2.3 auf den Blindkontakt 8.4 ge­ legt. Kommen die Massen beim Verschieben der Dauermagnete in den Einflußbereich deren Magnetfelder geschieht der Schaltvor­ gang sehr schnell, da das Kontaktfederelement als ein langes Pendel mit an dessen Ende angeordneter Masse zu betrachten ist. Auf Grund der Hebelübersetzung zwischen Einspannstelle und Masse einerseits und Einspannstelle und Kontaktelementen ande­ rerseits ist deshalb eine sichere Kontaktgabe und ein sicherer Kontaktdruck gewährleistet.If, for example, the driver has not put on his belt, ie the buckle is not inserted into the buckle, the retaining plate 9 arranged in the buckle presses the sliders 4.1 , 4.2 and with them also the permanent magnets 5.1 , 5.2 against the force of the springs 6.1 , 6.2 down. Each mass 7.1.1 , 7.2.1 enters the magnetic field of the permanent magnets 5.1 , 5.2 and is attracted by them. Here, the Kontaktpaa tion is open and the contact pair 7.1.3-8.1 7.1.2-8.2 closed, as well as the contact pair is 7.2.2-8.3 geöff net and the contact element defines ge to the dummy contact 7.2.3 8.4. If the masses move when moving the permanent magnets into the sphere of influence whose magnetic fields occur, the switching operation takes place very quickly, since the contact spring element is to be regarded as a long pendulum with mass arranged at its end. Because of the leverage between the clamping point and the mass on the one hand and the clamping point and contact elements on the other hand, a safe contact and a safe contact pressure is therefore guaranteed.

Legt nun der Fahrer seinen Gurt an und steckt die Schloßzunge in das Gurtschloß, so wird die Halteplatte 9 freigegeben und mit ihr können sich auch die Schieber 4.1, 4.2 und die Dauer­ magnete 5.1, 5.2 unter der Kraft der Federn 6.1, 6.2 nach oben bewegen. Hierbei gelangen die Massen 7.1.1, 7.2.1 aus dem Ein­ flußbereich der Magnetfelder, so daß die Vorspannkraft der Kontaktfederelemente 7.1, 7.2 dominiert, wodurch die zuvor ge­ schalteten Kontaktpaarungen unterbrochen werden und die Kon­ taktpaarungen 7.1.3-8.1 und 7.2.2-8.3 geschaltet werden.Now the driver puts on his belt and puts the buckle tongue in the buckle, so the holding plate 9 is released and with it the slider 4.1 , 4.2 and the permanent magnets 5.1 , 5.2 move up under the force of the springs 6.1 , 6.2 . Here, the masses 7.1.1 , 7.2.1 flow from a magnetic field, so that the biasing force of the contact spring elements 7.1 , 7.2 dominates, whereby the previously switched contact pairs are interrupted and the contact pairs 7.1.3-8.1 and 7.2.2 -8.3 can be switched.

Wie Fig. 2 zeigt, sind sämtliche gehäusefesten Kontaktelemente, die elektrisch kontaktierten Einspannstellen der Kontaktfeder­ elemente sowie Kontaktpunkte 10.1 bis 10.4 für in die Schalt­ kreise geschaltete Widerstände zur Erzeugung unterschiedlicher Schaltsignalpegel über Leiterbahnen 11 mit einem Anschlußkabel 12 verbunden. Das Gehäuse 1 besteht hierbei aus Kunststoff - vorzugsweise Polyetherimiol - und sämtliche Leiterbahnen der Schaltkreise sind durch Metallisierung - beispielsweise in ei­ ner Stärke von 25 µm als Sudzinnauflage - auf dasselbe aufge­ bracht, wobei die Leiterbahnen dreidimensional verlaufen kön­ nen. As shown in FIG. 2, all contact elements fixed to the housing, the electrically contacted clamping points of the contact spring elements and contact points 10.1 to 10.4 for resistors connected in the circuits for generating different switching signal levels are connected via conductor tracks 11 to a connecting cable 12 . The housing 1 is made of plastic - preferably polyetherimiol - and all the conductor tracks of the circuits are brought up to the same by metallization - for example in a thickness of 25 µm as a tin coating - the conductor tracks can be three-dimensional.

Mit der Erfindung ist also ein kompakter, funktionssicherer und einfach montierbarer Schalter geschaffen, welcher sämtliche Schalterelemente in einem gemeinsamen Gehäuse vereint.So with the invention is a compact, reliable and easy-to-install switch created, which all Switch elements combined in a common housing.

Obwohl der Schalter als Gurtschloßschalter beschrieben wurde, kann dieser selbstverständlich auch für andere Verwendungs­ zwecke, beispielsweise als Fahrzeugverdeckschalter, eingesetzt werden.Although the switch has been described as a buckle switch, this can of course also be used for other purposes purposes, for example as a convertible top switch become.

Gleichermaßen kann der Schalter auch noch variiert werden, in dem beispielsweise nur in einem Schenkel ein Schalter angeord­ net wird, der andere Schenkel hingegen nicht belegt wird.Similarly, the switch can also be varied in which, for example, arranged a switch only in one leg net, the other leg, however, is not occupied.

Auch kann der Schalter so ausgebildet sein, daß er statt U- förmig gestaltet nur einen Schenkel aufweist.The switch can also be designed so that instead of U- shaped only has one leg.
