Description

Wippenschalter für jeweils einen zweistufigen Betatigungshub Rocker switch for one two-stage actuation stroke each
Beschreibungdescription
Die Erfindung bezieht sich auf einen Wippenschalter für jeweils einen zweistufigen Betatigungshub, insbesondere als Fensterheberschalter für ein Kraftfahrzeug, mit einer in einem Gehäuse gelagerten Wipptaste, der eine Betatigungsplatte zur Beaufschlagung von mit Anschlußkontakten m Verbindung stehenden Schaltkontakten zugeordnet ist.The invention relates to a rocker switch for a two-stage actuation stroke, in particular as a window switch for a motor vehicle, with a rocker button mounted in a housing, which is assigned an actuation plate for acting on switching contacts connected to m contacts.
Aus der DE 195 37 296 AI ist eine Wippenschaltvorrichtung für einen zweistufigen Betatigungshub bekannt, die Teil einer Be- tatigungsemheit für elektrische Fensterheber eines Kraftfahrzeugs ist und ein Paar Betatigungsplatten unterhalb einer Langsmittell nie einer Wipptaste aufweist. Die Betatigungsplatten sind mittels elastischer Verbindungsarme gekoppelt und bilden so ein Betatigungsglied. Jede Betatigungsplatte beaufschlagt zwei Druckschalter, die durch eine hohle Vorsprunge aufweisende Schaltmatte mit darin angeordneten Kon- taktstucken und durch eine Basisplatte mit den beweglichen Kontaktstucken zugeordneten festen Kontaktstucken gebildet werden. Bei Betätigung der Wipptaste schwenkt diese um Tra- gerachsstum el eines Gehäuses, so daß sich die betätigte Sei- te der Wipptaste nach unten bewegt. Diese abwärts gerichtete Bewegung wird über die zugeordnete Betatigungsplatte auf die darunter angeordneten, rechten und linken Vorsprunge der Schaltmatte übertragen. Die Vorsprunge sind so angeordnet, daß sich aufgrund unterschiedlich einwirkender Drehmomente zuerst der linke Vorsprung verformt und durch die Berührung der hier angeordneten Kontaktstucke ein Stromkreis geschlossen wird, und nach einer weiteren Abwarts-Betatigung der Wipptaste auch der rechte Vorsprung durch die Betatigungsplatte nach unten gedruckt und ein weiterer Stromkreis geschlossen wird. Nach dem Loslassen der Wipptaste erfolgt e ne selbsttätige Ruckstellung derselben, wodurch die geschlossenen Stromkreise unterbrochen werden. Die Wippenschaltvorrich- tung umfaßt sonach eine Vielzahl von Kontaktstucken und Betatigungsplatten, die die entsprechenden Schaltfunktionen zur Ansteuerung der elektrischen Fensterheber bewirken, was einen äußerst komplexen Aufbau der Wippenschaltvorrichtung bedingt.From DE 195 37 296 AI a rocker switch device for a two-stage actuation stroke is known, which is part of an actuation unit for electric windows of a motor vehicle and a pair of actuation plates below a long-range never has a rocker button. The actuation plates are coupled by means of elastic connecting arms and thus form an actuation link. Each actuating plate acts on two pressure switches, which are formed by a switching mat having hollow projections with contact pieces arranged therein and by a base plate with fixed contact pieces assigned to the movable contact pieces. When the rocker button is pressed, it swivels around the support shaft of a housing so that the actuated side the rocker button is moved down. This downward movement is transmitted via the assigned actuating plate to the right and left projections of the safety mat arranged below it. The projections are arranged in such a way that the left projection deforms due to different torques and a circuit is closed by touching the contact pieces arranged here, and after another downward actuation of the rocker button, the right projection is also pressed down by the actuating plate and another circuit is closed. After releasing the rocker button, it is reset automatically, thereby interrupting the closed circuits. The rocker switch device accordingly comprises a multiplicity of contact pieces and actuating plates which bring about the corresponding switching functions for controlling the electric window regulators, which necessitates an extremely complex structure of the rocker switch device.
Des weiteren ist aus der DE 196 00 657 Cl ein mehrstufiger Wippenschalter bekannt, der im wesentlichen aus einer schwenkbar am Gehäuse gelagerten Wipptaste und vier von einer Fuhrungsplatte aufgenommenen Stoßein besteht, die unterhalb der Wipptaste angeordnet sind, wobei die Fuhrungsplatte innerhalb des Gehäuses parallel zu einer Leiterplatte angeordnet ist. Jeder Stößel wirkt mit einem Dom einer Schaltmatte zusammen, der ein Kontaktstuck aufnimmt, das bei einer Beauf¬ schlagung des Domes mit dem zugeordneten Stößel nach einem Einknicken des Domes auf einem festen Kontaktstuck zur Anlage kommt und einen Strompfad schließt. Jeweils zwei benachbarte Dome weisen eine unterschiedliche Stabilität auf, die ein Einknicken bei einer unterschiedlichen Krafteinwirkung zur Folge hat. Die zwei im Bereich jeder Stirnseite der Wipptaste angeordneten, die entsprechenden benachbarten Dome beaufschlagenden Stößel werden von einem zugeordneten Ansatz der Wipptaste betätigt, der auf ein in der Fuhrungsplatte schwenkbar sowie vertikal verschiebbar gelagertes Zwischenelement einwirkt. Hierzu weist das Zwischenelement waagerechte Fuhrungszapfen auf, die in korrespondierenden Nuten der Fuhrungsplatte emliegen. Das Zwischenelement ist als zweiarmiger Hebel ausgeführt, wobei jedem Hebelarm ein Stößel zugeordnet ist. Beim Betatigen der Wipptaste wird das zugeordnete Zwischenelement über den Ansatz der Wipptaste mit einer Druckkraft beaufschlagt, der die unterschiedlichen Druckkräfte der Dome entgegenstehen. Der Dom, der einem Betatigungshub einer ersten Stufe zugeordnet ist, knickt ein, wobei das Zwischenelement sowohl vertikal verschoben als auch verschwenkt wird, da der zugeordnete Hebelarm aufgrund der wirkenden Kräfte stets an dem entsprechenden Stößel anliegt. Bei einem Betatigungshub einer zweiten Stufe knickt auch der dem ersten Dom benachbarte Dom ein, wobei die beiden Hebelarme sich m einer waagerechten Lage befinden und das Zwischenelement um eine weitere Wegstrecke vertikal m Richtung der Dome verschoben wurde. Der Wippenschalter ist insofern nachteilig, als eine sehr aufwendige Schaltmechanik zur Realisierung eines zweistufigen Betatigungshubes vorgesehen ist.Furthermore, a multi-stage rocker switch is known from DE 196 00 657 Cl, which essentially consists of a rocker button pivotally mounted on the housing and four bumpers received by a guide plate, which are arranged below the rocker button, the guide plate inside the housing parallel to one Printed circuit board is arranged. Each ram cooperates with a dome of a keypad which receives a contact piece that comes at a Beauf ¬ suppression of the dome with the associated plunger for a buckling of the dome onto a fixed contact piece of the plant and includes a current path. Two adjacent domes each have a different stability, which prevents them from buckling under different forces Consequence. The two plungers arranged in the area of each end face of the rocker button, which act on the corresponding adjacent domes, are actuated by an associated attachment of the rocker button, which acts on an intermediate element which is pivotably and vertically displaceably mounted in the guide plate. For this purpose, the intermediate element has horizontal guide pins which rest in corresponding grooves in the guide plate. The intermediate element is designed as a two-armed lever, with a plunger being assigned to each lever arm. When the rocker button is actuated, the associated intermediate element is acted upon by a pressure force via the attachment of the rocker button, which opposes the different pressure forces of the domes. The dome, which is assigned to an actuation stroke of a first stage, buckles, the intermediate element being both vertically displaced and pivoted, since the associated lever arm always bears against the corresponding tappet due to the acting forces. During an actuation stroke of a second stage, the dome adjacent to the first dome also buckles, the two lever arms being in a horizontal position and the intermediate element being displaced a further distance vertically in the direction of the dome. The rocker switch is disadvantageous in that a very complex switching mechanism is provided for realizing a two-stage actuation stroke.
Es ist Aufgabe der Erfindung, einen Wippenschalter der eingangs genannten Art zu schaffen, der sich durch eine kompakte Bauweise mit möglichst geringer Anzahl von Bauteilen bei einer zuverlässigen Funktion auszeichnet.It is an object of the invention to provide a rocker switch of the type mentioned at the outset which is distinguished by a compact design with the smallest possible number of components and a reliable function.
Erfmdungsgemaß wird die Aufgabe dadurch gelost, daß dem Be- tatigungshub der ersten Stufe in jeder Richtung jeweils ein Schaltkontakt und dem Betatigungshub der zweiten Stufe in jeder Richtung ein gemeinsamer Schaltkontakt zugeordnet ist.According to the invention, the object is achieved in that the loading Actuation stroke of the first stage in each direction is assigned a switch contact and the actuation stroke of the second stage is assigned a common switch contact in each direction.
Aufgrund dieser Maßnahmen umfaßt der Wippenschalter für einen jeweils zweistufigen Betatigungshub lediglich drei Schaltkontakte, wodurch eine kompakte Bauweise und eine relativ geringe Anzahl von Bauteilen gegeben ist. Der jeweilige Schaltkontakt des Betatigungshubes der ersten Stufe liefert ein Signal über die Richtung, in der die Wipptaste beaufschlagt wurde, und lost eine erste Schalterfunktion aus. Die Betätigung des Schaltkontaktes, der dem Betatigungshub der zweiten Stufe zugeordnet ist, bewirkt eine weitere Signalgebung, die eine zweite Schalterfunktion, die der ersten Schalterfunktion zugeordnet ist, auslost. Beispielsweise lost der jeweilige Schaltkontakt, der dem Betatigungshub der ersten Stufe zugeordnet ist, eine Aufwärts- oder Abwartsbewegung eines zugeordneten Kraftfahrzeugfensters aus, die nach dem Loslassen der Wipptaste beendet ist. Der gemeinsame Schaltkontakt für den Betatigungshub der zweiten Stufe steuert eine Bewegung des entsprechenden Kraftfahrzeugfensters bis in dessen Endlage, deren Richtung durch den jeweils zuerst betätigten Schaltkontakt vorgegeben wird. Aufgrund des Zuschaltens der zweiten Schal-terfunktion zu der ersten Schalterfunktion ist eine zuverlässige Funktionsweise des Wippenschalters gew hrleistet. Die Kopplung der Funktion des jeweils zuerst beaufschlagten Schaltkontaktes mit der Funktion des gemeinsamen Schaltkontaktes kann elektrisch oder über eine entsprechende Ansteuerung einer Bordelektronik realisiert werden.Because of these measures, the rocker switch comprises only three switch contacts for a two-stage actuation stroke, which results in a compact design and a relatively small number of components. The respective switching contact of the actuation stroke of the first stage supplies a signal about the direction in which the rocker button was pressed and triggers a first switch function. The actuation of the switch contact, which is assigned to the actuation stroke of the second stage, causes further signaling, which triggers a second switch function, which is assigned to the first switch function. For example, the respective switching contact that is assigned to the actuation stroke of the first stage triggers an upward or downward movement of an assigned motor vehicle window, which is ended after the rocker button is released. The common switch contact for the actuation stroke of the second stage controls a movement of the corresponding motor vehicle window into its end position, the direction of which is predetermined by the switch contact that is actuated first. The connection of the second switch function to the first switch function ensures that the rocker switch functions reliably. The coupling of the function of the switch contact acted upon first with the function of the common switch contact can be realized electrically or by means of a corresponding control of an on-board electronics.
Nach einer vorteilhaften Ausgestaltung der Erfindung sind die drei Schaltkontakte in Form eines gleichschenkligen Dreiecks zueinander angeordnet, wobei die Schaltkontakte des Betatigungshubes der ersten Stufe jeweils an einem Eckpunkt der Basis und der Schaltkontakt des Betatigungshubes der zweiten Stufe an der Spitze des Dreiecks angeordnet ist. Zweckmaßi- gerweise verlauft die Basis des gleichschenkligen Dreiecks parallel zu einer Seitenwand des Gehäuses, wobei dessen Spitze unterhalb einer Achse der Wipptaste der gegenüberliegenden Seitenwand zugeordnet ist. Aufgrund dieser Anordnung der Schaltkontakte ist ein kompakter Aufbau des Wippenschalters sowie ein taktlies Erfassen der ersten und zweiten Stufe des Betatigungshubes gegeben. Die der ersten Stufe des Betatigungshubes zugeordneten Schaltkontakte sind m einem relativ großen Abstand zu der Achse der Wipptaste angeordnet, so daß ein entsprechender Hebelarm zu deren Beaufschlagung zur Verfugung steht, weshalb die Betätigung dieser Schaltkontakte eine geringere Kraft gegenüber der Betätigung des an der Spitze angeordneten Schaltkontaktes, zu dessen Beaufschlagung kein Hebelarm zur Verfugung steht, erfordert.According to an advantageous embodiment of the invention three switching contacts in the form of an isosceles triangle to each other, the switching contacts of the actuating stroke of the first stage being arranged at a corner point of the base and the switching contact of the actuating stroke of the second stage being arranged at the tip of the triangle. The base of the isosceles triangle expediently runs parallel to a side wall of the housing, the tip of which is assigned to the opposite side wall below an axis of the rocker button. Due to this arrangement of the switch contacts, the rocker switch is compact and there is a tactless detection of the first and second stages of the actuation stroke. The switching contacts assigned to the first stage of the actuation stroke are arranged at a relatively large distance from the axis of the rocker switch, so that a corresponding lever arm is available for acting on them, which is why the actuation of these switching contacts requires less force than the actuation of the switching contact arranged at the top , for the application of which no lever arm is available.
Vorteilhafterweise stutzt sicn die Betatigungsplatte über zugehörige Nocken auf den Schaltkontakten unter seitlichem Spiel relativ zu dem Gehäuse ab. Die Betatigungsplatte und die Nocken bilden eine Einheit, um die Bewegung der Wipptaste auf den oder die entsprechenden Schaltkontakte zu übertragen. Im weiteren ist keine Lagerung für die frei bewegliche Betatigungsplatte vorgesehen.Advantageously, the actuating plate is supported by associated cams on the switching contacts with lateral play relative to the housing. The actuation plate and the cams form a unit in order to transmit the movement of the rocker button to the corresponding switch contact or contacts. Furthermore, there is no storage for the freely movable actuating plate.
Um der Betatigungsplatte eine entsprechende Stabilit t zu verleihen und eine von der Betatigungsrichtung der Wipptaste abhangige Schwenkbewegung der Betatigungsplatte sicherzustel- len, ist zweckmaßigerweise die Betatigungsplatte mit einem außermittig zur Schalterlangsachse in Richtung des an der Spitze des Dreiecks liegenden Schaltkontaktes versetzten Steg versehen, an dem beidseitig zur Achse der Wipptaste jeweils ein Ansatz der Wipptaste anliegt. Aufgrund der außermittigen Anordnung des Steges verschwenkt die Betatigungsplatte bei einer einseitigen Krafteinleitung über den zugeordneten Ansatz um die entsprechende Seite des Dreiecks, m der die Schaltkontakte angeordnet sind. Im weiteren ist die Betatigungsplatte zwischen den Schaltkontakten und den Ansätzen der Wipptaste gehalten, so daß ein Verschieben der Betatigungsplatte durch Vibration nicht erfolgt.In order to give the actuation plate a corresponding stability and to ensure a pivoting movement of the actuation plate which is dependent on the actuation direction of the rocker button. len, the actuator plate is expediently provided with a web offset off-center to the longitudinal axis of the switch in the direction of the switching contact lying at the tip of the triangle, on each side of which there is an attachment of the rocker button to the axis of the rocker button. Due to the eccentric arrangement of the web, the actuating plate pivots when the force is applied on one side via the associated attachment around the corresponding side of the triangle, on which the switching contacts are arranged. Furthermore, the actuating plate is held between the switch contacts and the lugs of the rocker button, so that the actuating plate is not displaced by vibration.
Bevorzugt weist der Steg der Betatigungsplatte eine halbkreisförmige Freimachung für die Achse der Wipptaste auf. Die Freimachung ermöglicht die Schwenkbewegung der Betatigungsplatte, die nicht senkrecht zur Achse sondern um die entsprechende Seite des Dreiecks erfolgt, weshalb sich die Betatigungsplatte hierbei leicht verdreht.The web of the actuating plate preferably has a semicircular clearance for the axis of the rocker button. The franking enables the actuating plate to pivot, which is not perpendicular to the axis but around the corresponding side of the triangle, which is why the actuating plate rotates slightly here.
Zweckmaßigerweise umfaßt die Wipptaste zwei gegenüberliegende Lageraugen zur Aufnahme der Achse. Weiterhin greift zweckmaßigerweise die Achse m Lagerbohrungen in den Seltenwanden des Gehäuses ein, wobei jeweils zwischen der Seitenwand und dem Lagerauge der Wipptaste eine Scheibe angeordnet ist. Hierdurch ist eine zuverlässige Lagerung der Wipptaste gewährleistet. Die zwischen der jeweiligen Seitenwand des Gehäuses und dem entsprechenden Lagerauge der Wipptaste angeordnete Scheibe reduziert die Reibung zwischen diesen Bauteilen be m Verschwenken der Wipptaste.

Der Wippenschalter umfaßt eine in einem Geh use 1 gelagerte Wipptaste 2 mit langsseitig gegenüberliegend angeformte Lageraugen 3 zur Aufnahme einer Achse 4. Im weiteren weist die Wipptaste 2 Ansätze 5, 6 auf, die beidseitig zur Achse 4 angeordnet sind. Die Achse 4 ist in entsprechende Lagerbohrungen 7 m den Seltenwanden 8 des Gehäuses 1 eingesetzt, wobei zwischen den Lageraugen 3 der Wipptaste 2 und der zugeordneten Seitenwand 8 eine Scheibe 9 zur Verringerung der Reibung vorgesehen ist. Die Ansätze 5, 6 der Wipptaste 2 liegen an einem Steg 10 einer Betatigungsplatte 11 an, wobei der Steg 10 außermittig zur Schalterlangsachse 12 versetzt ist und eine halbkreisförmige Freimachung 13 für die Achse 4 der Wipptaste 2 aufweist. Die Betatigungsplatte 11 ist unter seitlichem Spiel m das Gehäuse 1 eingesetzt und stutzt sich über zugehörige Nocken 14, 15, 16 auf als Schnappscheiben ausgebildeten Schaltkontakten 17, 18, 19 des Wippenschalters ab, die m Form eines gleichschenkligen Dreiecks 20 zueinander angeordnet sind. Die Basis 21 des gleichschenkligen Dreiecks mit den jeweils end- seitigen Schaltkontakten 17, 19 verlauft parallel zu der entsprechenden Seitenwand 8 des Gehäuses 1. Der Schaltkontakt 18 an der Spitze 22 des Dreiecks 20 ist unterhalb der Achse 4 der Wipptaste 2 der gegenüberliegenden Seitenwand 8 zugeordnet .The rocker switch comprises a rocker button 2 mounted in a housing 1 with bearing eyes 3 formed on the long side opposite to accommodate an axis 4. Furthermore, the rocker button 2 has approaches 5, 6, which are arranged on both sides of the axis 4. The axis 4 is inserted into corresponding bearing bores 7 m in the rare walls 8 of the housing 1, a disk 9 being provided between the bearing eyes 3 of the rocker button 2 and the associated side wall 8 to reduce the friction. The lugs 5, 6 of the rocker button 2 rest on a web 10 of an actuating plate 11, the web 10 being offset off-center from the longitudinal axis 12 of the switch and having a semicircular clearance 13 for the axis 4 of the rocker button 2. The actuating plate 11 is inserted into the housing 1 with lateral play and is supported by associated cams 14, 15, 16 on switching contacts 17, 18, 19 of the rocker switch designed as snap disks, which are arranged in the form of an isosceles triangle 20 to one another. The base 21 of the isosceles triangle with the respective end-side switching contacts 17, 19 runs parallel to the corresponding side wall 8 of the housing 1. The switching contact 18 at the tip 22 of the triangle 20 is assigned to the rocker button 2 of the opposite side wall 8 below the axis 4 ,
Jeder Schaltkontakt 17, 18, 19 ist durch gegenüberliegende Ausnehmungen 23, die korrespondierende Arretierungsbolzen 24 aufnehmen, gehalten, wobei die Arretierungsbolzen 24 in einem Boden 25 des Gehäuses 1 angeordnet sind. Auf dem Boden 25 befindet sich eine Leiterplatte 26 mit den den Schaltkontakten 17, 18, 19 zugeordneten Kontaktbahnen, deren AnschlußkontakteEach switch contact 17, 18, 19 is held by opposite recesses 23, which receive corresponding locking bolts 24, the locking bolts 24 being arranged in a base 25 of the housing 1.

Bei einem Verschwenken der Wipptaste 2 in Richtung des PfeilsWhen the rocker switch 2 is pivoted in the direction of the arrow
28 um einen Betatigungshub erster Stufe 29 wirkt der Ansatz 6 der Wipptaste 2 auf den Steg 10 der Betatigungsplatte 11. Da dieser m Richtung der Spitze 22 des Dreiecks 20 versetzt zur Schalterlangsachse 12 angeordnet ist und die Nocken 16 der Betatigungsplatte 11 auf den zugeordneten Schaltkontakten 17, 18, 19 aufliegen, verschwenkt die Betatigungsplatte 11 um den Schenkel 30 des Dreiecks 20. Aufgrund der wirkenden Hebelverhaltnisse druckt der dem Schaltkontakt 17 zugeordnete Nocken 16 diesen nieder, so daß ein entsprechender erster Stromkreis der Leiterplatte 26 geschlossen wird. Der durch den Schaltkontakt 17 geschlossene erste Stromkreis bewirkt die Ansteuerung eines Fensterhebermotors, der ein zugeordnetes Kraftfahrzeugfenster öffnet. Nach dem Loslassen der Wipptaste 2 wird dieser Stromkreis geöffnet und das Kraftfahrzeugfenster verharrt m der erreichten Position. Durch die Ruckstellbewegung des Schaltkontaktes 17 erfolgt eine Ruckstellung der Wipptaste 2 in die Ausgangslage .28 by an actuation stroke of the first stage 29, the extension 6 of the rocker button 2 acts on the web 10 of the actuation plate 11. Since this is offset in the direction of the tip 22 of the triangle 20 from the longitudinal axis 12 of the switch and the cams 16 of the actuation plate 11 on the associated switching contacts 17 . 18, 19 rest, the actuating plate 11 pivots about the leg 30 of the triangle 20. Because of the effective lever conditions, the cam 16 assigned to the switching contact 17 presses it down, so that a corresponding first circuit of the printed circuit board 26 is closed. The first circuit, which is closed by the switch contact 17, controls a window lift motor which opens an associated motor vehicle window. After releasing the rocker switch 2, this circuit is opened and the motor vehicle window remains in the position reached. The reset movement of the switch contact 17 causes the rocker button 2 to be reset to the starting position.
Das Verschwenken der Wipptaste 2 in Richtung des Pfeils 28 um einen Betatigungshub zweiter Stufe 31 bewirkt die zuvor erläuterte Schwenkbewegung der Betatigungsplatte 11 um den Schenkel 30 des Dreiecks 20 und das Niederdrucken des Schaltkontaktes 17 am Eckpunkt 32 der Basis 21 des Dreiecks 20 sowie das Schließen des ersten Stromkreises, dem die öffnende Bewegung des Kraftfahrzeugfensters zugeordnet ist. Anschließend erfolgt die Betätigung des Schaltkontaktes 18 an der Spitze 22 des Dreiecks 20 durch den Nocken 15 der Betatigungsplatte 11, wobei die Betätigung des Schaltkontaktes 18 wegen der wirkenden Hebelverhaltnisse einen erhöhten Kraftaufwand gegenüber der Betätigung des Schaltkontaktes 17 beansprucht. Das Schließen eines zweiten Stromkreises durch den Schaltkontakt 18 bewirkt ebenfalls eine Ansteuerung des Fensterhebermotors, der das Kraftfahrzeugfenster entweder schnell und/oder in eine geöffnete Endlage verfahrt. Nach dem Loslassen der Wipptaste 2 kehrt diese aufgrund der Ruckstellbewegungen der Schaltkontakte 17, 18 in ihre Ausgangslage zu- ruck und das Kraftfahrzeugfenster bleibt entweder m der erreichten Position stehen oder verfahrt in seine geöffnete Endlage .The pivoting of the rocker button 2 in the direction of arrow 28 by an actuation stroke of the second stage 31 causes the previously explained pivoting movement of the actuation plate 11 around the leg 30 of the triangle 20 and the depression of the switching contact 17 at the corner point 32 of the base 21 of the triangle 20 and the closing of the first circuit to which the opening movement of the motor vehicle window is assigned. The switching contact 18 at the tip 22 of the triangle 20 is then actuated by the cam 15 of the actuating plate 11, the actuation of the switching contact 18 requiring an increased force compared to the actuation of the switching contact 17 because of the lever ratios acting. The closing of a second circuit by the switch contact 18 also causes the window lift motor to be actuated, which either moves the motor vehicle window quickly and / or into an open end position. After releasing the rocker switch 2, it returns to its starting position due to the reset movements of the switch contacts 17, 18. jerk and the motor vehicle window either stops in the position reached or moves to its open end position.
Wird die Wipptaste 2 in Richtung des Pfeils 33 um einen Betatigungshub erster Stufe 29 verschwenkt, beaufschlagt der Nokken 5 die Betatigungsplatte 11, wodurch diese um den Schenkel 34 des Dreiecks 20 verschwenkt wird. Der Nocken 16 der Betatigungsplatte 11 druckt den zugeordneten Schaltkontakt 19 auf die Leiterplatte 26, wodurch ein Stromkreis geschlossen wird, der den entsprechenden Fensterhebermotor ansteuert, der eine schließende Bewegung des Kraftfahrzeugfensters verursacht. Das Loslassen der Wipptaste 2 bewirkt ein Offnen des Stromkreises und das damit verbundene Verharren des Kraftfahrzeugfensters m der erreichten Position. Die Ruckstellung der Wipptaste 2 erfolgt durch die Ruckstellbewegung des Schaltkontaktes 19, der die mit der Wipptaste 2 über den Ansatz 5 in Verbindung stehende Betatigungsplatte 11 in eine zum Boden 25 des Gehäuses 1 parallele Lage verschwenkt.If the rocker switch 2 is pivoted in the direction of the arrow 33 by an actuation stroke of the first stage 29, the cam 5 acts on the actuation plate 11, as a result of which the latter is pivoted about the leg 34 of the triangle 20. The cam 16 of the actuating plate 11 presses the associated switch contact 19 onto the printed circuit board 26, as a result of which a circuit is closed which controls the corresponding window motor, which causes the motor vehicle window to close. Releasing the rocker button 2 causes the circuit to open and the associated motor vehicle window to remain in the position reached. The rocker button 2 is reset by the reset movement of the switching contact 19, which pivots the actuating plate 11 connected to the rocker button 2 via the extension 5 into a position parallel to the bottom 25 of the housing 1.
Das Verschwenken der Wipptaste 2 m Richtung des Pfeils 33 um einen Betatigungshub zweiter Stufe 31 hat die zuvor erläuterte Schwenkbewegung der Betatigungsplatte 11 um den Schenkel 34 des Dreiecks 20 und das Niederdrucken des Schaltkontaktes 19 am Eckpunkt 35 der Basis 21 des Dreiecks 20 sowie die damit verbundene schließende Bewegung des Kraftfahrzeugfensters zur Folge. Nachdem der Schaltkontakt 19 seine Endlage auf der Leiterplatte 26 erreicht hat, wird der Schaltkontakt 18 durch den entsprechenden Nocken 15 der Betatigungsplatte 11 beaufschlagt und der zweite Stromkreis auf der Leiterplatte 26 geschlossen. Hierdurch verfahrt der angesteuerte Fensterheber- motor das Kraftfahrzeugfenster entweder schnell und/oder in eine geschlossene Endlage. Das Loslassen der Wipptaste 2 bewirkt, daß das Kraftfahrzeugfenster entweder in der erreichten Position stehen bleibt oder in seine geschlossene Endlage verfahrt. Ferner kehrt die Wipptaste 2 aufgrund der Ruckstellbewegungen der Schaltkontakte 18, 19 in ihre Ausgangslage zurück.The pivoting of the rocker button 2 m in the direction of arrow 33 by an actuation stroke of the second stage 31 has the previously explained pivoting movement of the actuation plate 11 around the leg 34 of the triangle 20 and the depression of the switching contact 19 at the corner point 35 of the base 21 of the triangle 20 and the associated closing movement of the motor vehicle window result. After the switch contact 19 has reached its end position on the printed circuit board 26, the switch contact 18 is acted upon by the corresponding cam 15 of the actuating plate 11 and the second circuit on the printed circuit board 26 is closed. As a result, the controlled window lift motor the motor vehicle window either quickly and / or in a closed end position. Releasing the rocker switch 2 causes the motor vehicle window to either remain in the position reached or to move into its closed end position. Furthermore, the rocker button 2 returns to its initial position due to the reset movements of the switching contacts 18, 19.
Das Zusammenwirken der m den Eckpunkten 32, 35 des Dreiecks 20 angeordneten Schaltkontakte 17, 19 der jeweils ersten Stufe 29 mit dem der Spitze 22 des Dreiecks 20 zugeordneten Schaltkontakt 18 ist durch eine entsprechende elektrische Schaltung oder durch die Ansteuerung einer Bordelektronik realisiert. Die Bordelektronik speichert m der jeweils ersten Stufe eine Richtungsinformation, ausgelost durch den Schaltkontakt 17 oder den Schaltkontakt 19 für das Offnen oder das Schließen des Kraftfahrzeugfensters, und ordnet der Richtungsinformation gegebenenfalls nach dem Erreichen der jeweils zweiten Stufe 31 eine weitere, durch den Schaltkontakt 18 bewirkte Information zu. Diese Information der jeweils zweiten Stufe 31 des Betatigungshubes veranlaßt das Kraftfahrzeugfenster zu einer schnellen Bewegung und/oder zu einer Bewegung in eine der Endlagen, wobei die Bewegung in Abhängigkeit von der zuvor gespeicherten Information das Kraftfahrzeugfenster entweder öffnet oder schließt. BezugszeichenlisteThe interaction of the switching contacts 17, 19 of the respective first stage 29 arranged at the corner points 32, 35 of the triangle 20 with the switching contact 18 assigned to the tip 22 of the triangle 20 is realized by a corresponding electrical circuit or by the control of on-board electronics. The on-board electronics store direction information in the first stage in each case, triggered by the switch contact 17 or the switch contact 19 for opening or closing the motor vehicle window, and if necessary after the second stage 31 has been reached, assigns the direction information to further one caused by the switch contact 18 Information about. This information of the respective second stage 31 of the actuation stroke causes the motor vehicle window to move quickly and / or to move into one of the end positions, the movement either opening or closing the motor vehicle window depending on the information previously stored.
