The sleeves thus have a multiple function. They not only form the holder and guide of the bearing element, but also its attachment to the band pocket with the aid of the cover.

An embodiment of the hinge provides that the bearing part is formed by webs projecting on both sides from the end region of the tab engaging in the bearing element, which webs have one of the cross-sectionally curved surfaces. The free end of the flap is so on the two opposite level boundary surfaces supported with the arcuate surfaces and therefore can act in this embodiment, in the same way as a bearing with a pivot pin.

A variant in this context provides that the two arcuate surfaces are a total of sections of a single circular arc. It is thereby ensured that the arcuate surfaces always and thus rest at each pivotal position on the flat boundary surfaces.

It is therefore also possible that the entire bearing part is formed as a cylindrical thickening of the free end of the tab. However, it can then require a little more material, but the production is made simpler.

It is also proposed that for adjusting the flap relative to the bearing element transversely to the hinge axis an inserted into an opening in the flap threaded rod is provided, which engages in a rotatably, but immovably held in the bearing element threaded nut. As a result, this adjustment can be made possible with simple technical means and above all, a simple adjustment is possible even after the installation of the hinge. Furthermore, a self-locking adjustment is given, which does not solve itself.

A simple structural design provides in this context that the threaded nut has at its outer boundary radial bores for applying an adjusting tool.

It is further provided that the adjusting screw for pivoting and fixing of the tab in the bearing element passes through the tab and is supported by their ends on the opposite boundary surfaces of the bearing element. Also, this adjustment can be done in a simple manner after the installation of the hinge, the desired simple construction and especially the required self-locking are guaranteed.

In connection with the adjustment in various directions, it is particularly advantageous if both the threaded nut and the adjusting screw are freely accessible via openings in the cover.
