  10. Vorrichtung nach Anspruch 9, dadurch gekennzeichnet, daß in dem entriegelten Betriebszustand der erste Hebel (421) durch den Übertragungsmechanismus (41) der gegen die dritte elastische Kraft (Feder 53) in eine zweite relative Drehposition bezüglich des Schiebers (32) positioniert ist, in welchem die Öse (320) durch wegrücken relativ zum Freischnitt (420) des ersten Hebels und zur ersten Schräge (323) offen ist und es dem Zwischenglied (313) erlaubt, von dessen Eingriffszustand in dessen Freigabezustand durch Gleiten dessen zweiten Endes (213b) an der ersten Schräge (323) und durch freies Gleiten am diesem zweiten Ende (313b) in der Bohrung (322) des Schiebers (32) auf einem Teil wenigstens der Bahn zu gelangen, die der Schiebers (32) zwischen dessen aktiven Position und dessen inaktiven Position nimmt.
  11. Vorrichtung nach einem der vorangegangnen Ansprüche, dadurch gekennzeichnet, daß beim Verlauf des Betätigungsteils (311) von dessen Ruheposition in dessen Eingriffsposition und beim Eingriffszustand des Zwischenglieds (313) dieses Zwischenglied eine Zwischenposition passiert, in der das Zwischenglied der ersten Achse (Z) durch dessen erstes und zweites Ende (313a, 313b) aufgerichtet ist.
  12. Vorrichtung nach einem der vorangegangenen Ansprüche in Kombination mit Anspruch 9, dadurch gekennzeichnet, daß der Ausschnitt (420) des ersten Hebels (421) eine zweite Schräge (420a) aufweist und daß in der Eingriffsposition des Betätigungsteils (311) und im Eingriffszustand des Zwischenglieds (313) das zweite Ende (313b) das Zwischenglied (313a) an der ersten und der zweiten Schräge (323, 420a) eine erste bzw. eine zweite Abstützkraft ausübt, wobei die erste Abstützkraft größer als die zweite Abstützkraft ist und beispielsweise gleich oder doppelt so groß wie die zweite Abstützkraft ist.
  13. Vorrichtung nach einem der vorgegangenen Ansprüche in Kombination mit Anspruch 9, dadurch gekennzeichnet, daß das Betätigungsteil in Richtung dessen Ruheposition durch eine vierte elastische Kraft (Feder 54) vorgespannt ist, so daß der Ausschnitt (420) des ersten Hebels (421) durch eine dritte Schräge (420b) geringer Neigung bezüglich des Zwischenglieds (313) in dem Freigabezustand umgeben ist, und daß in der Eingriffsposition des Betätigungsteils (311) und dem freigegebenen Betriebszustand des Zwischenglieds (313) das zweite Ende (313b) des Zwischenglieds (313) translatorisch den ersten Hebel (421) von dessen erster relativer Drehposition in dessen zweite relative Drehposition unter dem Einfluß der dritten elastischen Kraft (Feder 54) passieren läßt, indem an der dritten Schräge (420b) abgestützt wird.
  14. Vorrichtung nach einem der vorangegangen Ansprüche in Kombination mit Anspruch 6, dadurch gekennzeichnet, daß das Zwischenglied (313) durch einen U-förmigen Träger gebildet ist, der einen ersten lateralen Schenkel (313a) und einen zweiten lateralen Schenkel (313b) aufweist, die jeweils das erste und das zweite Ende dieses Zwischenglieds (312) bilden und die miteinander durch eine gemeinsame Basis (313c) verbunden sind.
  15. Vorrichtung nach einem der vorangegangenen Ansprüche, dadurch gekennzeichnet, daß der Übertragungsmechanismus (41) einen zweiten Hebel (411) umfaßt, der schwenkbar an dem Gehäuse (1) angebracht ist und eine Hebung (411a) aufweist, die selektiv angetrieben ist, beispielsweise durch einen externen beweglich Vorsprung, der in dem Gehäuse quer zu einem ersten Fenster (11) vorsteht, das in diesem Gehäuse (1) ausgebildet ist, und eine kinematische Verbindung aufweist, die die Drehposition des ersten Hebels (421) in Abhängigkeit von wenigstens einer Drehposition des zweiten Hebels (411) bestimmt, wobei diese kinematische Verbindung wenigstens einen Antriebszapfen (411b) umfaßt, der an diesem zweiten Hebel (411) getragen ist.
  16. Vorrichtung nach Anspruch 15, dadurch gekennzeichnet, daß die kinematische Verbindung außerdem einen dritten Hebel (412) umfaßt, der schwenkbar an dem Gehäuse (1) angebracht ist, wobei dieser dritter Hebel (412) selektiv durch den zweiten Hebel (411) angetrieben ist und einen Antriebsfinger (412a) in Abstützung an dem zweiten Hebel (421) sowie eine Nut (421b) umfaßt, in die der Antriebszapfen (411b) des zweiten Hebels (411) verschiebbar aufgenommen ist, wobei der erste und der zwei te Hebel (411, 412) jeweils Drehbewegungen geringer Winkelamplitude und größere Winkelamplitude ausführen, wenn der erste Hebel (421) von seiner ersten relativen Drehposition in seine zweite relative Drehposition übergeht.
