  • other fastening means such as screws or locking means omitted at least partially.
  • the radiation source used may comprise only a single laser radiation-radiating element, so that only one laser beam always acts on the adjustment unit during assembly and the adjustment unit, on the one hand, and the radiation source, on the other hand, are to be successively positioned during assembly in such a way that one laser beam successively illuminates the one laser beam makes necessary connections between components of the adjustment.
  • the radiation source used may also comprise several elements emitting laser radiation, so that during the assembly of the adjustment unit, the laser radiation impinges on the adjustment unit simultaneously at several locations (from different, spaced-apart space locations) in order to connect components there as intended.

  • components in or on the housing can also be fixed to the ground by the laser welding in order to avoid rattling noises.
  • an elastic element (spring element) may be arranged, which acts on at least one of the functional components to be fastened to the housing under pretension, that this functional component is biased in its intended position on or in the housing.
