Abstract
A head up display mirror holder arrangement for a motor vehicle includes a picture generation unit producing a light field. A mirror reflects the light field such that the light field is visible to the driver as a virtual image. A mirror holder has two opposite ends and an activation feature. The two opposite ends are aligned along a rotational axis of the mirror. The mirror holder retains the mirror. Each of two bushings is coupled to a respective opposite end of the mirror holder. A calibration switch has minimum proximity to the activation feature of the mirror holder.

A head up display arrangement for a motor vehicle, the arrangement comprising:
- a first body including:
- a picture generation unit configured to produce a light field that is reflected off of a windshield of the motor vehicle such that the light field is visible to a human driver of the motor vehicle as a virtual image;
- and
- at least one arcuate recess and/or at least one projection;
- and
- a second body configured to be fixed to a frame of the motor vehicle, the second body including:
- at least one recess positioned and sized to receive a respective said projection of the first body;
- and/or
- at least one projection positioned and sized to be received in a respective said arcuate recess of the first body.
A head up display method for a motor vehicle, said method comprising:
- using a picture generation unit to produce a light field that is reflected off of a windshield of the motor vehicle such that the light field is visible to a human driver of the motor vehicle as a virtual image;
- providing a first body including:
- the picture generation unit;
- and
- at least one arcuate recess and/or at least one projection;
- fixing a second body to a frame of the motor vehicle, the second body including:
- at least one arcuate recess if the first body includes the at least one projection;
- and/or
- at least one projection if the first body includes the at least one recess;
- mating the first body and the second body together such that each said projection is received in a respective said arcuate recess;
- rotating the first body relative to the second body until the virtual image is in a desired rotational position;
- and
- fixing the first body relative to the frame of the motor vehicle after the rotating step.
A head up display arrangement for a motor vehicle, the arrangement comprising:
- at least one mirror;
- a windshield;
- a first body including:
- a picture generation unit configured to produce a light field that is reflected off of the at least one mirror and the windshield such that the light field is visible to a human driver of the motor vehicle as a virtual image;
- and
- at least one arcuate recess and/or at least one projection;
- and
- a second body configured to be fixed to a frame of the motor vehicle, the second body including a window configured to allow the light field to pass through the window before the light field is reflected by the at least one mirror, the second body further including:
- at least one arcuate recess positioned and sized to receive a respective said projection of the first body;
- and/or
- at least one projection positioned and sized to be received in a respective said arcuate recess of the first body.
