Head-up Display in Which a Concave Mirror Is Optimized and/or Lowered into the Park Position by Way of an Eccentric Bearing With a Separate Drive

A projector unit for a transparent display for a vehicle, the projector unit comprising:

• an imaging unit for generating light beams containing desired display content;
• a concave mirror placed in a beam path of the light beams, such that the light beams exit the projector unit in a specific shape and direction, to subsequently be reflected by a partially transparent reflective panel in a user's field of vision into an eyebox, thus showing the user content of the display in a form of a virtual image behind the reflective panel;
• wherein:
• the concave mirror is rotatable about a mirror shaft connected to the concave mirror by a mirror shaft drive to adjust the eyebox position, which is rotatably supported for this in a primary bearing;
• and
• the primary bearing on one end of the mirror shaft is supported off-center in a secondary bearing, which is drivable by an independently controlled eccentric drive such that the second bearing can be rotated about its eccentric axis, which is fixed in place in relation to the projector unit, to obtain a translatory transversal movement of the mirror shaft, and thus the concave mirror.
