Description
Die Erfindung betrifft einen Stuhl mit nachgiebig gelagerter Rückenstütze, deren Tragarm an einer SteUe am StuhlgesteU angelenkt und an einer zweiten Stelle durch eine einsteUbare Feder gegen das StuhlgesteU abgestützt ist. Durch Veränderung der Einstellung der Feder kann nur der Widerstand, welchen die Rückenstütze der Veränderung ihrer Neigung entgegengesetzt, verändert, nicht aber die Neigung der Lehne verstellt werden, was aber vielfach erforderlich ist.The invention relates to a chair with resiliently mounted backrest, the support arm of which is hinged to a control on the chair gesture and at a second point is supported against the chair gesture by an adjustable spring. Through change the adjustment of the spring can only be the resistance of the back support Change of its inclination opposite, changed, but not the inclination of the backrest can be adjusted, but this is often necessary.
Gemäß der Erfindung ist die zweite StützsteUe des Tragarmes vermittels eines am Stuhl· ig gesteU oder Tragarm befestigten Gewindebolzens und einer darauf einstellbaren, am anderen Teil drehbar gelagerten Gewindehülse in ihrer Lage zum Sitz veränderbar, um die Neigung des Tragarms verstellen zu können. Ein Äusführungsbeispiel des Erfindungsgegenstandes ist in der Zeichnung dargesteUt, und zwar zeigtAccording to the invention, the second support part of the support arm is arranged on the chair by means of a ig gesteU or support arm attached threaded bolt and one adjustable on the other Part rotatably mounted threaded sleeve in its position to the seat can be changed to the To be able to adjust the inclination of the support arm. An embodiment of the subject matter of the invention is shown in the drawing, namely shows

Die Rückenstütze 1 sitzt am oberen Ende eines Tragarmes 2, der unten rechtwinklig abgebogen ist und mit seinem unteren Ende bei 3 gelenkig am Stuhlgestell oder an der Sitzplatte 4 befestigt ist. Bei der Neigungsverstellung der Lehne schwingt der Arm 2 um die Achse des Bolzens 3. Ein zweiter Abstützungspunkt für den Tragarm wird durch folgende Einstellmittel gebildet: Am StuhlgesteU oder unterhalb der Sitzplatte ist ein Augbolzen 5 am Zapfen 6 angelenkt. Auf den Augbolzen ist eine mit Innengewinde verse· hene Gewindehülse 7 aufgeschraubt, welche oben einen Flansch 8 trägt, der auf dem Tragarm 2 aufruht, und unten eine Flügelmutter 9. Die Gewindehülse 7 ist von einer Schraubenfeder 10 umgeben, welche sich einerends auf den Tragarm 2 und anderends auf ein Handrad 11 abstützt, das auf dem mit Außengewinde versehenen unteren Teil der Gewindehülse 7 aufschraubbar ist. Mittels des Handrades 11 wird die Federspannung eingestellt. Die Neigung der Rückenstütze wird durch einfaches Drehen der Flügelmutter eingestellt, indem beim Auseinanderschrauben von Gewindehülse 7 und Bolzen S der durch die Einstellmittel gebildete zweite Unterstützungspunkt des Tragarmes weiter vom Sitz abrückt, und umgekehrt beim Zusammenschrauben. Die Feder 10 bewirkt eine federnde Abstützung der Rückenstütze, und zwar in jeder verstellten Lage derselben.The back support 1 sits at the upper end of a support arm 2, which is at right angles below is bent and with its lower end at 3 articulated on the chair frame or on the Seat plate 4 is attached. When the backrest is inclined, arm 2 swings around the axis of the bolt 3. A second support point for the support arm is through The following adjustment means are formed: On the chair gesture or below the seat plate is a Eye bolt 5 hinged on pin 6. There is an internal thread on the eye bolt. hene threaded sleeve 7 screwed, which above carries a flange 8 on the Support arm 2 rests, and below a wing nut 9. The threaded sleeve 7 is of a Coil spring 10 surround, which one end on the support arm 2 and at the other end supported on a handwheel 11, which is on the externally threaded lower part the threaded sleeve 7 can be screwed on. The spring tension is adjusted by means of the handwheel 11 set. The incline of the backrest is adjusted by simply turning the wing nut set by the screwing apart of threaded sleeve 7 and bolt S formed by the adjustment means second support point of the support arm moves further away from the seat, and vice versa when screwing together. The spring 10 provides a resilient support for the back support, in every misaligned position of the same.
