Unter„verrasten" soll insbesondere eine rein formschlüssige Verbindung verstanden werden, die zur Abstützung der von dem zumindest einen Energiespeicherelement ausgeübten Kraft vorgesehen ist und die durch eine Relativbewegung zwischen dem Gate element to be understood. By "latching" should be understood in particular a purely positive connection, which is provided to support the force exerted by the at least one energy storage element and force by a relative movement between the
Rastelement und dem Kulissenelement in einer Richtung, die zumindest im Wesentlichen senkrecht zu einer Richtung, entlang der die Kraft orientiert ist wirkt, gelöst werden kann. Unter„zumindest im Wesentlichen senkrecht" soll dabei insbesondere verstanden werden, dass die Richtung, in der die Kraft wirkt, mit der Richtung, entlang der die Relativbewegung erfolgt, einen Winkel von zumindest 80 Grad einschließt.  Locking element and the link element in a direction which acts at least substantially perpendicular to a direction along which the force is oriented, can be solved.

Freigabeelement 18 unbetätigt ist. Das erste Rastelement 21 ist einstückig mit dem Gehäuse 19 ausgeführt. Release element 18 is unconfirmed. The first latching element 21 is designed in one piece with the housing 19.
Das zweite Rastelement 22 ist fest mit dem Freigabeelement 18 verbunden. Es ist, äquivalent zu dem ersten Rastelement 21 , ebenfalls nach innen gerichtet und für einen Eingriff in die Rastkulisse des Kulissenelements 20 vorgesehen. Wenn das erste Rastelement 21 in Eingriff mit der Rastkulisse ist, ist das zweite Rastelement 22 zwischen zwei Zähnen der Rastkulisse angeordnet. Ein Abstand, den die beiden Rastelemente 21 , 22 zueinander aufweisen, weicht von einem Vielfachen des Abstands zweier Zähne ab. The second latching element 22 is firmly connected to the release element 18. It is, in accordance with the first latching element 21, also directed inwards and provided for engagement in the latching backdrop of the link element 20. When the first detent element 21 is in engagement with the detent gate, the second detent element 22 is arranged between two teeth of the detent gate. A distance which the two latching elements 21, 22 have relative to one another deviates from a multiple of the distance between two teeth.
Durch eine Betätigung des Freigabeelements 18 ist das Rastelement 22 in einer Richtung senkrecht zu der Erstreckungsrichtung 14 der Kolben 12, 13 bewegbar. Bei einer Betätigung des Freigabeelements 18 wird das By an actuation of the release element 18, the latching element 22 is movable in a direction perpendicular to the extension direction 14 of the pistons 12, 13. Upon actuation of the release element 18 is the
Rastelement 22 nach innen ausgelenkt. Das Freigabeelement 18 ist senkrecht zu der Erstreckungsrichtung 14 um einen Weg bewegbar, der größer ist als eine Tiefe der Rastkulisse, wodurch bei einer Betätigung des Freigabeelements 18 das Kulissenelement 20 nach innen gedrückt wird.

Das Detent element 22 deflected inwards. The release member 18 is movable perpendicular to the extension direction 14 by a distance which is greater than a depth of the detent gate, whereby upon actuation of the release member 18, the link element 20 is pressed inwards. As a result of the movement of the release element 18, the gate element 20 is deflected by the latching gate, whereby the latching connection between the first latching element 21 and the gate element 20 is released. The
Freigabeelement 18 ist somit dazu vorgesehen, die Rastverbindung zwischen dem ersten Rastelement 21 und dem Kulissenelement 20 zu lösen. Release element 18 is thus provided to release the latching connection between the first latching element 21 and the link element 20.
Gleichzeitig während des Lösens, d.h. bevor die Rastverbindung zwischen dem ersten Rastelement 21 und dem Kulissenelement 20 vollständig gelöst ist, wird das zweite Rastelement 22 in die Rastkulisse hineinbewegt.  At the same time during release, i. before the locking connection between the first locking element 21 and the link element 20 is completely dissolved, the second locking element 22 is moved into the detent gate.
Das zweite Rastelement 22 ist für eine Rastverbindung nach dem Lösen der Rastverbindung zwischen dem Kulissenelement 20 und dem ersten The second latching element 22 is for a latching connection after releasing the latching connection between the link element 20 and the first
Rastelement 21 vorgesehen. Nach dem Lösen der Rastverbindung zwischen dem ersten Rastelement 21 und dem Kulissenelement 20 werden die Kolben 12, 13 durch die Kraft der Energiespeicherelemente 16, 17 bewegt, bis das zweite Rastelement 22 an einem Zahn der Rastkulisse des Kulissenelements 20 anliegt. Ein Weg, um den die Kolben 12, 13 mit dem Betätigen des  Detent element 21 is provided. After releasing the latching connection between the first latching element 21 and the link element 20, the pistons 12, 13 are moved by the force of the energy storage elements 16, 17 until the second latching element 22 rests against a tooth of the latching backdrop of the link element 20. A way by which the pistons 12, 13 with the actuation of the
Freigabeelements 18 bewegt werden, ist kleiner als der Abstand, den die Zähne aufweisen. Release member 18 is moved, is smaller than the distance that have the teeth.
Wird das Freigabeelement 18 wieder losgelassen, wird das mit dem If the release element 18 is released again, that will be with the
Freigabeelement 18 verbundene Rastelement 22 aus der Rastkulisse hinausbewegt. Die Kolben 12, 13 werden dadurch wieder für eine Bewegung freigegeben, wodurch die Energiespeicherelemente 16, 17 die Kolben 12, 13 weiterbewegen, bis das erste Rastelement 21 am nächsten Zahn der Release element 18 connected locking element 22 is moved out of the detent gate. The pistons 12, 13 are thereby released again for movement, whereby the energy storage elements 16, 17, the pistons 12, 13 continue to move until the first locking element 21 on the next tooth
Rastkulisse anliegt. Die Kolben 12, 13 sind somit durch das Betätigen des Freigabeelements 18 und das nachfolgende Loslassen des Freigabeelements 18 um einen durch die Rastkulisse definierten Weg bewegbar, wobei die Kraft zur Bewegung der Kolben 12, 13 lediglich von den Energiespeicherelementen 16, 17 bereitgestellt wird. Rastkulisse rests. The pistons 12, 13 are thus movable by actuation of the release element 18 and the subsequent release of the release element 18 about a path defined by the detent gate, wherein the force for movement of the pistons 12, 13 is provided only by the energy storage elements 16, 17.
