Fig. 1 zeigt eine Draufsicht und Fig. 2 eine Seitenansicht einer Bedientastatur 1, insbesondere
für eine Kraftfahrzeug-Klimaanlage, die frontseitig in ein Armaturenbrett 2 einbaubar ist,
bestehend aus einem Gehäuse 3, in dem elektrische und elektronische Bauteile angeordnet
sind, wobei mehrere Tasten 4 der Tastatur auf Schalter 5 (Fig. 9) einwirken, die auf einer
Leiterplatte 6 (Fig. 9) angeordnet sind.Fig. 1 shows a plan view and Fig. 2 shows a side view of a
Es ist vorgesehen, daß die Tasten 4, in Fig. 5 und 6 dargestellt, von der Bedienseite her mit
Führungsansätzen 7 auf Führungsstempel 10 aufgeschoben und innerhalb einer Verrastung
11 gehalten sind, die eine Verstellung der Taste 4 innerhalb zweier Anschläge 12, 13 begrenzt,
wobei der von der Taste 4 betätigte Schalter 5 innerhalb der Verstellung ein- und

Es ist vorteilhaft, wenn Führungsstempel 10 und Tastenführungsansatz 7 eine Schwalbenschwanzführung
14 bilden (Fig. 13), die durch Ausnehmungen 15, 16 der Leiterplatte 6 und
einer Trägerplatte 17 hindurchragt (Fig. 9). Diese Maßnahme ermöglicht die Anordnung der
Leiterplatte 6 sehr dicht an den Tasten 4, wobei der sogenannte Schubladeneffekt, d. h.
Kippen der Tasten 4, nicht auftreten kann. It is advantageous if the
Die Verrastung 11 ist durch einen Sperransatz 20 auf dem Führungsstempel 10 und eine
Ausnehmung 21 in dem Führungsansatz 7 gebildet, wie aus Fig. 9 erkennbar ist, wobei der
Sperransatz 20 unter elastischer Verformung der Führungsansatzwandung in die Ausnehmung
21 einrastet. Hierdurch entfallen Verbindungs- bzw. Sicherungselemente.The
Dadurch, daß mit dem Schalter 5 kontaktierende Tastenfiächen 22 der Tasten 4 in einem
Tastenrahmen 23 bestehen, ergibt sich ebenfalls eine flache Bauweise, wobei der Tastenrahmen
23 die Taste 4 selbst gegen Verformung sichert (Fig. 5 und 6).Characterized in that with the
Es ist vorgesehen, daß die frontseitig sichtbaren Tastenflächenwände 24 den Tastenrahmen
23 überragen (Fig. 5 und 6) und in Tastenführungsausnehmungen 25 einer Gehäusefrontwandung
26 geführt sind (Fig. 4). Hierdurch ist ein gefälliges Aussehen erreicht worden und
ein Lichtausfall von nicht dargestellten Leuchtelementen aus dem Inneren der Bedientastatur
1 verhindert.It is envisaged that the
Es ist vorteilhaft, wenn die Leiterplatte 6 von der Trägerplatte 17 getragen wird, die mit
Klippsansätzen 27 in einen Gehäuserahmen 30 eingesetzt und in Klippsschlitzen 31 des
Gehäuserahmens 30 gehalten ist (Fig. 3). Hierdurch ist eine wirtschaftliche Montage der
Bedientastatur 1 erreicht worden (Fig. 9).It is advantageous if the
Zur Anzeige der gewünschten, eingestellten Regeldaten weist die Bedientastatur 1 eine bekannte
LCD-Anzeige auf (Fig. 10), wobei die Trägerplatte 17 mit umgebogenen Greifansätzen
32 ein LCD-Element 33 hält, das über verspannte Leitgummistücke 34 mit Leitern der
Leiterplatte 3 kontaktiert ist. Durch die verspannten Leitgummistücke 34 ist eine dauerelastische
Halterung des LCD-Elements 33 erreicht worden.To display the desired, set control data, the
Für eine einfache Montage der Bedientastatur 1 in eine Öffnung des Armaturenbretts 2 ist
vorgesehen, daß die Trägerplatte 17 einen den Gehäuserahmen 30 umgreifenden Federansatz
35 aufweist (Fig. 7 und 8), der in das Armaturenbrett 2 bei eingesetzter Bedientastatur
1 durch die Armaturenbrettwandung eingefedert ist und diese Armaturenbrettwandung
mit einer komplementären Hakenausbildung 36 umklammert, wobei die entgegengesetzte
andere Seite des Gehäuserahmens 30 (Fig. 2) mit einem Steckeraufnahmeteil 37 und der
Gehäusefrontwandung 26 eine Aufnahmenut 38 für die Armaturenbrettwandung bildet.
Somit braucht die Bedientastatur 1 nur mit der Aufnahmenut 38 in die Öffnung des Armaturenbretts
2 bzw. über die Armaturenbrettwandung gesteckt und mit der anderen Seite in die
Öffnung eingedrückt zu werden, so daß der Federansatz 35 einfedert und die Armaturenbrettwandung
mit der Hakenausbildung 36 umklammert. Damit ist eine einfache Befestigung
der Bedientastatur erreicht.For easy assembly of the
Wie in Fig. 9 bis 11 dargestellt, die Querschnitte der Bedientastatur 1 zeigen, ist vorgesehen,
daß die umgebogenen Greifansätze 32 an beiderseits der Trägerplatte 17 angebogene
Winkelansätze 40 bestehen, wobei Ausnehmungen 41 im Biegebereich 42 (Fig. 7 und 8) so
angeordnet sind, daß Schenkelansätze 43, 44 oberhalb und unterhalb des Biegebereichs 42
bestehen, so daß die Schenkelansätze 43, 44 die Winkelansätze 40 gegenüber den Gehäuserahmenwänden
45 parallel ausrichten können.As shown in FIGS. 9 to 11, which show cross sections of the
Zusätzlich zu diesen Maßnahmen kann die Trägerplatte 17 in den Ausnehmungen 16, durch
welche die Führungsstempel 10 hindurchragen, angebogene Arretierflächen 46 aufweisen,
an denen sich die Leiterplatte 17 maßgenau abstützen kann.In addition to these measures, the
Fig. 12 zeigt eine Ausschnittsvergrößerung aus Fig. 11, aus der ersichtlich ist, wie der
Klippansatz 27 der Trägerplatte 17 in den Klippschlitz 31 eingerastet hat, und ebenso wie die
Schenkelansätze 43 und 44 die Winkelansätze 40 gegenüber den Gehäuserahmenwänden
45 parallel ausrichten.FIG. 12 shows an enlarged detail from FIG. 11, from which it can be seen how the
