  • the upper bearing shell 3 according to FIG. 4a does not necessarily have to be semicircular but can also be angular for manufacturing reasons.
  • the lower bearing shell 9 can also be dispensed with (FIG. 7b), so that the pin 6 of the tilting flap 7 is only held from above by the upper bearing shell 3 or by the lugs 30, while the lower bearing of the pin 6 by the Top of the plate 1 or the film 22 glued to the plate is formed outside the bearing blocks 2.
