• leadthroughs on the single-joint regions of each of the two hinge halves concentric to one another and to the hinge axis and further, the leadthroughs from one hinge half to the other having different diameters, such that the leadthroughs of the two hinge halves can be inserted one into the other in the manner of a male and female plug part;
• and
• bearing bushes made of a maintenance-free bearing material are interposed between the leadthroughs of the two hinge halves.
