  • the screw is secured against rotation about the axis of rotation relative to the hinge housing and preferably relative to the drive housing, so that translational movement of the screw member relative to the hinge housing is effected by means of a relative rotation about the axis of rotation relative rotation between the threaded spindle and the screw, whereby the pivot arm is pivotable relative to the hinge housing by means of the screw.
  • the threaded spindle in a first direction of rotation rotated about the axis of rotation relative to the hinge housing, so for example, thereby the screw is translationally moved in a first direction relative to the hinge housing.
  • the swivel arm is pivoted in a first pivoting direction relative to the hinge housing. If, for example, the threaded spindle is rotated about the axis of rotation relative to the hinge housing by means of the electric motor in a direction opposite to the first direction of rotation, the screw element is thereby moved translationally in a second direction opposite the first direction relative to the hinge housing.
