  Schutzblock für   kopfstützen   von Operationsstühlen. 



   Die Erfindung besteht aus einem Block von Papierblättern, welcher mit geeigneten   Vorrichtungen   versehen ist, um an der eigenartig geformten Kopfstütze von zahnärztlichen   Operationsstühlon   angebracht zu worden, zwecks hygienischen Schutzes insofern, als nach jeder Benutzung das gebrauchte Blatt abgerissen werden kann, um ein frisches Blatt zu präsentieren. 



   Die Eigenart der   zahnärztlichen   Kopfstützen besteht darin, dass zwei seitliche Backen, welche die hintere   Kopihilfte   zwischen sich zu fassen haben, durch einen Steg miteinander verbunden sind. Hierauf gründet sich die Befestigungsvorrichtung der Erfindung. Dieselbe besteht darin, dass der Block mit zwei Bändern versehen wird, deren eines oberhalb, deren anderes unterhalb des Steges verläuft, damit der Block durch die Bewegungen des Kopfes oder der Hände des Operateurs nicht zum Verrutschen gebracht werden kann. Der zwischen beiden Bändern befindliche Steg verhindert dies. Zweckmässig wird man   elastibche Bänder   wählen, um, falls der Block über beide Backen hinweggespannt werden soll, ein Einsinken des Kopfes zwischen die Backen zu ermöglichen. 



   Die untenstehende schematische Zeichnung erläutert die Erfindung in einer   Hinteransicht   des auf der   Kopfstütze   befestigten Blockes. a ist der Block,   b und b'sind   die Backen der Kopfstütze, c und d die beiden Gummibänder,   e der Backonsteg.

  Protective block for headrests of operating chairs.



   The invention consists of a block of paper sheets, which are provided with suitable devices to be attached to the peculiarly shaped headrest of dental operating chairs, for the purpose of hygienic protection in that after each use the used sheet can be torn off in order to get a fresh sheet present.



   The peculiarity of the dental headrests is that two side jaws, which have to hold the rear copier between them, are connected to one another by a web. The fastening device of the invention is based on this. The same consists in that the block is provided with two straps, one above and the other below the web so that the block cannot be caused to slip by the movements of the surgeon's head or hands. The bridge between the two bands prevents this. It is advisable to choose elastic straps in order to allow the head to sink in between the jaws if the block is to be stretched across both jaws.



   The schematic drawing below explains the invention in a rear view of the block attached to the headrest. a is the block, b and b 'are the jaws of the headrest, c and d are the two rubber bands, e the backon bridge.
