  Vorrichtung zum selbsttätigen Lösen und Feststellen eines in verschiedenen Höhenlagen einstellbaren und verdrehbaren Stuhisitzes. 



   Die Erfindung betrifft einen Stuhl mit drehbarem, der Höhe nach verstellbaren) Sitz, bei dem eine Sperrklinke beim Anheben des Sitzes ein Verstellen einer Zahnstange nach oben gestattet, sie jedoch gegen   Rückwärtsbewegung   so lange sichert, bis die Sperrklinke in der höchsten Stellung der Zahnstange aus der Bahn ihrer Zähne gebracht ist und hierauf den Niedergang der Zahnstange bis in ihre tiefste Lage gestattet, in welcher die Sperrklinke wieder in die Bahn der Zähne der Zahnstange tritt.   Ähnlich wirkende Ein-   richtungen sind an verstellbaren   Rückenteiles   von Matratzen bekannt geworden. Die Erfindung wird daher in der Übertragung dieser Einrichtung auf einen Stuhl mit drehbarem und verstellbarem Sitz in der dadurch hervorgerufenen Abänderung gesehen.

  Device for the automatic release and locking of a chair seat that can be adjusted and rotated at different heights.



   The invention relates to a chair with a rotatable, height-adjustable seat, in which a pawl allows a rack to be adjusted upwards when the seat is raised, but secures it against backward movement until the pawl is in the highest position of the rack The path of their teeth is brought and then the decline of the rack is allowed to its lowest position, in which the pawl enters the path of the teeth of the rack again. Devices with a similar effect have become known on adjustable back parts of mattresses. The invention is therefore seen in the modification caused thereby in the transfer of this device to a chair with a rotatable and adjustable seat.



   In the drawing, FIG. 1 is a sectional view of the upright chair, FIG. 2 is a plan view of the mechanism, and FIGS. 3 and 4 are sectional and elevational views of the locking arrangement
 EMI1.1
   The ring c also serves to guide the rack a and is adapted to the cross section of the same at the top.



   A sheet metal disc is attached to the column, which has the adjusting device in the foot
 EMI1.2
 higher altitudes are brought. If the seat is to be lowered again, the following device comes into effect: On both sides of the rack a are embedded in the ring e Ilei) el b, the guidance of which is so tight that it is stiffened when the rack
 EMI1.3
 is held in the desired positions.
