   Die Aufweitbarkeit des Schalenringes kann beispielsweise dadurch erreicht sein, dass der Bodenrand entsprechende innenseitige Einschlitzungen bzw. winkelige Ausschnitte aufweist. Auch kann der Bodenrand innenseitig durch sich beim Aufschieben nach aussen umlegende Zungen gebildet sein. Eine andere Möglichkeit besteht darin, den Schalenring aus aufweitbarem Werkstoff zu bilden und die Aufweitbarkeit   z. B.   durch entsprechende Stärkenbemessung nach dem den Haltering bildenden Teil zu bzw. in diesem Teil aufzuheben bzw. nahezu aufzuheben. 



   PATENTANSPRÜCHE : 
1. Elastische Dichtung in Balgform für allseitig bewegliche Gelenke, insbesondere Kugelgelenke, deren einer Rand zur Festlegung am Gelenkgehäuse und deren anderer, die vom sich konisch nach der dem Gelenkgehäuse abgewandten Seite verjüngenden Gelenkzapfen durchgriffene öffnung begrenzender Rand zum dichten Umfassen des Gelenkzapfens bestimmt ist sowie aussenseitig eine Umfangsnut zur 
 EMI3.1 
 Gelenkzapfens (2) bestimmte und die Durchgriffsöffnung für diesen begrenzende Balgrand (7) vor dem Aufbringen der Dichtung auf den Gelenkzapfen (2) einen grössten Aussendurchmesser von geringerer Grösse als die Grösse des Innendurchmessers des Halteringes (9) und einen beim Aufschieben der Dichtung auf den Gelenkzapfen zusammen mit der Gesamtheit des Balgrandes aufzuweitenden Innendurchmesser aufweist,

   so dass beim Aufschieben und dem damit verbundenen Aufweiten des gesamten Balgrandes der Haltering (9) in die Umfangsnut (8) gelangt und den Balgrand gegen den Zapfen verspannt.

   The shell ring can be expanded, for example, in that the bottom edge has corresponding slots or angled cut-outs on the inside. The bottom edge can also be formed on the inside by tongues that fold outwards when it is pushed on. Another possibility is to form the shell ring from expandable material and the expandability z. B. by appropriate strength measurement after the part forming the retaining ring to or in this part to be canceled or almost to be canceled.



   PATENT CLAIMS:
1.Elastic seal in bellows form for joints that move in all directions, in particular ball and socket joints, one edge of which is intended to be fixed to the joint housing and the other edge delimiting the opening through which the conically tapering joint pin extends to the side facing away from the joint housing is intended for tightly enclosing the joint pin and on the outside a circumferential groove for
 EMI3.1
 Hinge pin (2) and the passage opening for this delimiting bellows edge (7) before the seal is applied to the hinge pin (2) has a largest outer diameter of smaller size than the size of the inner diameter of the retaining ring (9) and one when the seal is pushed onto the Has pivot pin together with the entirety of the bellows edge to be expanded inside diameter,

   so that when the entire bellows edge is pushed on and the associated widening, the retaining ring (9) enters the circumferential groove (8) and braces the bellows edge against the pin.
 EMI3.2
