Wegfall kommen, dieselben vielmehr unmittelbar durch den Zug der Schnüre 21, 22 aus den Zahnstangen 19 gehoben werden, so dafs die ruckweise Bewegung beim Niedrigerstellen vermieden und eine vollständig geräuschlose, sowie ruckfreie Abwärtsbewegung durch Anordnung eines blasebalgä'hnlichen Luftkissens zwischen Kopfpolster und Rahmen erzielt wird.Elimination come, the same rather directly by pulling the cords 21, 22 from the racks 19 are raised, so that the jerky movement when lowering avoided and a completely noiseless, as well as jerk-free downward movement by arrangement a bellows-like air cushion between the head cushion and frame is achieved.

Fig. 3 einen Schnitt nach Linie χ'-λγ1 von Fig. ι undFig. 3 shows a section along line χ'-λγ 1 of Fig. Ι and
Fig. 4 die Hinteransicht.4 shows the rear view.
Um ein vollständig geräuschloses und ruckfreies Abwärtsbewegen des Kopfpolsters 1 zu erzielen, sind die keilförmigen Zähne 171 des Rahmens 16, sowie die in diese Zähne eingreifenden Stifte 91 der Bügel 9 in Wegfall gekommen.In order to achieve a completely noiseless and jerk-free downward movement of the head pad 1, the wedge-shaped teeth 17 1 of the frame 16, as well as the pins 9 1 of the bracket 9 engaging in these teeth, have been omitted.
An deren Stelle tritt nunmehr ein Blasebalg <z, dessen unterer Theil am Rahmen 2 befestigt ist, während der obere Theil durch Gurte d mit den Spiralfedern 4 verbunden ist, die zwischen Kopfpolster und Blasebalg angeordnet sind. Durch Schnüre c (Fig. 4) ist der Blasebalg aufserdem noch mit dem Kopfpolsterrahmen verbunden.In their place there is now a bellows, the lower part of which is fastened to the frame 2, while the upper part is connected by straps d to the spiral springs 4 which are arranged between the head cushion and the bellows. The bellows is also connected to the headrest frame by cords c (Fig. 4).
Die Wirkungsweise ist ähnlich derjenigen der Vorrichtung nach dem Haupt-Patent. Um das Polster höher zu stellen, drückt man den durch eine Schnur 28 mit dem Kopfpolster verbundenen Hebel 27 abwärts, wobei die Rollen 10 unter Einwirkung ihrer federnden Stützen 9 in den Zahnstangen 19 nach vorn gedrückt werden, während der Blasebalg sich gleichzeitig ausdehnt.The mode of operation is similar to that of the device according to the main patent. Around To raise the cushion, press the head cushion by a cord 28 connected lever 27 downward, the rollers 10 under the action of their resilient Supports 9 in the racks 19 are pushed forward while the bellows is expands at the same time.
Die Schnüre 21,22, welche das Niedrigerstellen bewirken, sind durch Oesen im Rahmen 16 geleitet und mit den in die Zahnstangen 19 greifenden Stutzen 9 verbunden, so dafs nach Anziehen dieser Schnüre die Stützen 9 aus den Zahnstangen herausgehoben werden.The cords 21:22, which are the lowering cause are passed through eyelets in the frame 16 and with the in the racks 19 gripping connecting pieces 9, so that after tightening these cords the supports 9 be lifted out of the racks.
Infolge des Druckes, welchen der Kranke auf das Kopfpolster ausübt, wird nun der Blasebalg zusammengeprefst und das Kopfpolster senkt sich unter Vermeidung jeglicher Stöfse langsam abwärts.As a result of the pressure which the patient exerts on the head-cushion, now becomes the The bellows are compressed and the head cushion lowers avoiding any Slowly push down.
Damit der Rahmen 16 beim Niedrigerstellen kein Geräusch verursacht, sind an demselben Stifte b (Fig. 2) angebracht, welche auf am Rahmen 2 befestigte Blattfedern c einwirken.So that the frame 16 does not cause any noise when lowering, pins b (FIG. 2) are attached to the same, which act on leaf springs c attached to the frame 2.
