8 greift ein säbelförmiges Ende eines an der Grundplatte 6 gelagerten Kipnhebels^. 10, der parallel zur Grundplatte 6 und im wesentlichen zur Platte 1 verläuft und an seinem anderen Ende einen nicht gezeigten Handgriff für die Höhenverstellung hat. Durch Betätigen des Hebels 10 wird die eigentliche Rückenlehne mit der Platte 1, der Lasche 2 mit Führungsschiene 4 und der Lasche 3 mit Führungsschiene 5 höhenverstellt, ohne daß die beiden Laschen eine Abstandsänderung erfahren.8, a saber-shaped end of a grips on the base plate 6 mounted rocker arm ^. 10, which is parallel to the base plate 6 and runs essentially to the plate 1 and at its other end a handle, not shown, for height adjustment Has. By actuating the lever 10, the actual backrest with the plate 1, the bracket 2 with the guide rail 4 and the bracket 3 with guide rail 5 adjusted in height without the two brackets experiencing a change in distance.
Die Wölbungsverstellvorrichtung der Rückenlehne ist in Form eines Eowdenzuges ausgebildet. Der Mantel 11 des Bowdenzuges ist mit Durchhang bzw. Spiel mit einem Ende in senkrechter Richtung am oberen Abschnitt der Führungsschiene 5 und mit dem anderen Ende in horizontaler Richtung an der Grundplatte 6 befestigt. Die Drahtseele 12 des Bowdenzuges ist mit ihrem oberen Ende an der Lasche 2 am oberen Ende der Führungsschiene 4 und mit ihrem anderen Ende an einem Gewindestift 13 befestigt, der mit einer Gewindebohrung eines verdrehbar und axial an der Grundplatte 6 festgelegten Drehgriffs 14 in Eingriff steht. Der Gewindestift 13 ist mit einem an der Grundplatte 6 abgestützen Querstück 16 am Verdrehen verhindert, so daß durch Drehen des Drehgriffs 14 der Gewindestift 13 aus dem Griff herausbewegt bzw. in dem Griff hineinbewegt und somit der obere Abschnitt der Drahtseele 12 gegenüber dem oberen Ende des Mantels 11 verlängert bzw. verkürzt wird. Da die Platte 1 auch bei in größtem Abstand stehenden Laschen 2 und 3 noch etwas verwölbt ist, werden die beiden Laschen ständig auseinandergedrückt und somit die Drahtseele 12 ständig auf Zug beansprucht. Durch Verkürzen der Drahtseele entgegen dieser Zugkraft kann die Verwölbung der Platte 1 vergrößert werden; durch Verlängern der Drahtseele kann sich die Platte entspannen und nimmt einen Zustand geringerer Verwölbung ein, indem die Laschen 2 und 3 in einen größeren Abstand gedrückt werden. Eine selbständige Verstellung kann durch geeignete Mittel, wie beispielsweise selbsthemmendes Gewinde zwischen Gewindestift und Drehgriff, verhindert werden.The curvature adjustment device of the backrest is designed in the form of an Eowden cable. The jacket 11 of the Bowden cable is with slack or play with one end in the vertical direction on the upper portion of the guide rail 5 and with the other end is attached to the base plate 6 in the horizontal direction. The wire core 12 of the Bowden cable is with her upper end attached to the tab 2 at the upper end of the guide rail 4 and at its other end to a threaded pin 13, which engages with a threaded hole of a rotatable and axially fixed rotary handle 14 on the base plate 6 stands. The threaded pin 13 is prevented from rotating with a crosspiece 16 supported on the base plate 6, so that through Turning the rotary handle 14 moves the threaded pin 13 out of the handle or into the handle and thus moves the upper section the wire core 12 is lengthened or shortened relative to the upper end of the jacket 11. Since plate 1 is also used with in tabs 2 and 3 that are at the greatest distance are still slightly arched, the two tabs are constantly pushed apart and thus the wire core 12 is constantly under tension. By shortening the wire core against this tensile force, the Warpage of the plate 1 can be increased; by lengthening the wire core, the plate can relax and take you A state of less warping by pressing tabs 2 and 3 a greater distance apart. An independent one Adjustment can be made by suitable means, such as a self-locking thread between the threaded pin and the rotary handle, be prevented.
