It can be seen that with the drawn Position of the upper plate 16 of the stop pin 33 in the recess 24 is received. At the other end position there is the stop pin 33 in the recess 23rd

    Ein Steuerarm 34 ist bei einem Ende über einen Zapfen 35 an der unteren Platte 17 an einer Stelle angelenkt, der mit der Längsmittellinie des Langloches 25 ausgerichtet ist. Diese Stelle, ein Loch 43, befindet sich neben einem Seitenrand der unteren Platte 17, wobei noch die Lagerbuchse 36 und die Stopmutter 37 dargestellt sind. A control arm 34 is over at one end a pin 35 on the lower plate 17 at one point articulated with the longitudinal center line of the elongated hole 25 is aligned. This point, hole 43, is located itself next to a side edge of the lower plate 17, wherein still the bearing bush 36 and the stop nut 37 shown are.

    Beim entgegengesetzten Ende ist dieser Steuerarm 34 über das Gleitelement 19 an der oberen Platte 16 angelenkt, also an einer Stelle seitlich der Längsmittellinie des Langloches 25.At the opposite end is this control arm 34 via the sliding element 19 on the upper plate 16 articulated, i.e. at a point to the side of the longitudinal center line of slot 25.

    Vom Steuerarm 34 steht nach unten ein Kugelzapfen 38 ab, der durch eine bogenförmige Öffnung 39 hindurch verläuft und mit dem einen Ende einer Gasdruckfeder 40 verbunden ist. Diese Gasdruckfeder 40 ist bei ihrem entgegengesetzten Ende über einen Stift 41, der in ein Loch 42 der unteren Platte 17 eingesteckt ist an derselben angelenkt. Es ist ersichtlich, dass dieses Loch 42 mit der verlängerten Längsmittellinie des Langloches 25 ausgerichtet ist, mit welcher Längsmittellinie auch das Loch 43 zur Aufnahme des Zapfens 35 des Steuerarmes 34 ausgerichtet ist.From the control arm 34 is a ball pin down 38 from that through an arcuate opening 39 runs and with one end of a gas pressure spring 40 is connected. This gas pressure spring 40 is at her opposite end via a pin 41 which is in a Hole 42 of the lower plate 17 is inserted on the same hinged. It can be seen that this hole 42 with the elongated longitudinal center line of the elongated hole 25 is aligned with which longitudinal center line that too Hole 43 for receiving the pin 35 of the control arm 34 is aligned.

    Die Funktionsweise dieser Steuervorrichtung ist wie folgt.The operation of this control device is as follows.

    Wird die obere Platte 16 (die mit einem Sitzpolsterteil verbunden ist) basiert auf der Darstellung gemäss Figur 2 im Gegenuhrzeigersinn gedreht, bewirkt dies eine Schwenkbewegung des Steuerarmes 34, der folglich die Platte 16 entlang des Langloches 25 wegstösst. Somit bewirkt die Drehbewegung der oberen Platte 16 über den Steuerarm 34 eine zwangsweise, der Drehbewegung überlagerte geradlinige Verschiebebewegung der Platte 16. Das heisst, bezogen auf die Figuren 3A-3D, der Sitzpolsterteil wird von der beschriebenen Gerade 15 wegverschoben, und durch eine entsprechende Wahl der Dimensionen der einzelnen Teile der Steuervorrichtung 8 genau um eine solche Strecke, dass in jeglicher Drehstellung des Sitzpolsterteils 3 dessen Eckstelle 14 auf der Geraden 15 verbleibt.If the upper plate 16 (the one with a seat cushion part is connected) based on the representation rotated counterclockwise according to FIG this is a pivoting movement of the control arm 34, which consequently the plate 16 pushes away along the elongated hole 25. Thus, the rotational movement of the top plate 16 causes the control arm 34 a forced, the rotational movement superimposed rectilinear shifting movement of the plate 16. Das means, based on the figures 3A-3D, the seat cushion part is moved away from the straight line 15 described, and by an appropriate choice of the dimensions of the individual parts of the control device 8 exactly by one such a route that in any rotational position of the seat cushion part 3 whose corner point 14 on the straight line 15 remains.

    Während der ersten Phase der Drehbewegung der oberen Platte 16 wird die Gasdruckfeder 40 entgegen ihrer elastischen Rückstellkraft gespannt.During the first phase of the rotary movement of the upper plate 16, the gas pressure spring 40 against it elastic restoring force tensioned.

    Die Gasdruckfeder 40 ist in der maximal gespannten, d.h. zusammengedrückten Stellung, wenn die obere Platte 16 um 45° gedreht worden ist. Diese Stellung entspricht einer Totpunktstellung der Drehbewegung. Nach einem weiteren Drehen über die 45°-Stellung hinaus wird die obere Platte 16 mit dem betreffenden Sitzpolsterteil durch die Gasdruckfeder 40 in die andere Endlage gedrückt und dort gehalten. Für den Benützer ist dieses sehr bequem, weil er den Sitzpolsterteil nur ein wenig mehr als 45° drehen muss, weil danach die weitere Drehbewegung von selbst erfolgt.The gas pressure spring 40 is in the maximum tensioned i.e. compressed position when the top Plate 16 has been rotated by 45 °. This position corresponds to a dead center position of the rotary movement. To a further turn beyond the 45 ° position the upper plate 16 with the relevant seat cushion part pressed by the gas pressure spring 40 into the other end position and kept there. This is very convenient for the user, because he's just a little more than the seat cushion part 45 ° because then the further rotation of done itself.

    Die Wirkungsweise der Führungsvorrichtung ist insbesondere in den Figuren 3A-3G verdeutlicht.The operation of the guide device is particularly illustrated in Figures 3A-3G.

    Figur 3A zeigt eine Endstellung, d.h. Grundstellung des zweiten Sitzpolsterteiles 3, in der Sitzkonfiguration. Wird nun der Sitzpolsterteil 3 von der Stellung 3A in die Stellung 3B gedreht, wird er bzw. die obere Platte 16 aufgrund des Steuerarmes 34 im Langloch vorgeschoben, so dass die Eckstelle 14 trotz der Drehung auf der Geraden 15 verbleibt. Die Gasdruckfeder 40 wird gegen ihre elastische Rückstellkraft gespannt, d.h. zusammengedrück. Währen der fortgeführten Drehbewegung von der Stellung nach Fig. 3B zur Stellung nach Fig. 3C wird die obere Platte 16 noch weiter im Langloch 25 vorgeschoben, die Gasdruckfeder 40 noch weiter zusammengedrückt.Figure 3A shows an end position, i.e. initial position of the second seat cushion part 3, in the seat configuration. Now the seat cushion part 3 from the position 3A rotated to position 3B, it becomes the upper one Plate 16 advanced due to the control arm 34 in the slot, so that the corner point 14 despite the rotation on the straight line 15 remains. The gas pressure spring 40 is against their elastic restoring force is tensioned, i.e. together amount oppressive. During the continued rotation of the Position according to FIG. 3B to the position according to FIG. 3C upper plate 16 advanced further in slot 25, the gas spring 40 further compressed.

    Danach wird die Stellung nach Fig. 3D erreicht, welche eine 45°-Stellung ist. In dieser Stellung sind das Langloch 25, der Steuerarm 34 und die Gasdruckfeder 40 miteinander ausgerichtet. Die Gasdruckfeder 40 befindet sich in ihrer maximal gespannten Stellung.Then the position according to FIG. 3D is reached, which is a 45 ° position. In this position are the slot 25, the control arm 34 and the gas pressure spring 40 aligned with each other. The gas pressure spring 40 is in its maximum cocked position.

    Beim weiteren Drehen des Sitzpolsterteiles 3 in der Richtung gemäss Fig. 3E, wird nun die obere Platte 16 durch den Steuerarm 34 entlang dem Langloch 25 zurückgezogen, so dass sich die Eckstelle 14 immer noch entlang der Geraden 15 bewegt. Jedoch ist für diese weitergeführte Bewegung keine weitere manuelle Kraftaufwendung notwendig, weil nun die elastische Rückstellkraft der Gasdruckfeder 40 auf den Steuerarm 34 einwirkt. Somit bewegt sich der Sitzpolsterteil 3 über die Stellung nach Fig. 3F in die Endstellung nach Fig. 3G und damit befindet sich der Sitzpolsterteil 3 in der Liegekonfiguration. Dabei wird die Ausnehmung 23 in der oberen Platte 16 durch die Gasdruckfeder 40 gegen den Anschlagzapfen 33 gepresst gehalten, d.h. der Sitzpolsterteil 3 ist nun in dieser Stellung arretiert.When turning the seat cushion part 3 3E, the top plate is now 16 withdrawn through the control arm 34 along the elongated hole 25, so that corner 14 is still along the straight line 15 moves. However, this is continued for Movement no further manual effort required, because now the elastic restoring force of the gas pressure spring 40 acts on the control arm 34. So moved the seat cushion part 3 over the position according to Fig. 3F in the end position according to Fig. 3G and is thus the seat cushion part 3 in the lying configuration. there the recess 23 in the upper plate 16 through the Gas pressure spring 40 held pressed against the stop pin 33, i.e. the seat cushion part 3 is now in this Position locked.

    Beim Zurückdrehen des Sitzpolsterteiles 3 von der Liegekonfiguration nach Fig. 3G in die Sitzkonfiguration nach Fig. 3A, erfolgen dieselben Wirkungen der einzelnen Bauteile der Führungsvorrichtung 8 wie dieses beim vorgängigen Drehen der Fall war.When turning back the seat cushion part 3 of the lying configuration according to Fig. 3G in the seat configuration 3A, the same effects of each occur Components of the guide device 8 like this one previous turning was the case.
