Abstract
The invention relates to a tilt-stable rotating joint suitable for technical orthopedic components, including a forked external joint part with two limbs whose parallel inner walls pointing towards each other form a slit of a given width and are provided with flush continuous holes. A flat inner joint part protrudes into the slit and a continuous hole, and a shaft arrangement protruding through the continuous holes forms a rotating bearing surface with a cover surface. The tilt-stability is increased because the shaft arrangement is formed by sections protruding from the inner joint part, having an external diameter corresponding to the internal diameter of the continuous holes of the limbs. Stability is also increased by the fact that the shaft arrangement is rotationally fixed to the inner joint part and sliding bearings are formed between the walls of the continuous holes of the limbs and the sections of the shaft arrangement.
