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 mirror holder arrangement for a motor vehicle, the arrangement comprising:
- a picture generation unit configured to produce a light field;
- a mirror configured to reflect the light field such that the light field is visible to the driver as a virtual image;
- a mirror holder having two opposite ends and an activation feature, the two opposite ends being aligned along a rotational axis of the mirror, the mirror holder being configured to retain the mirror;
- two bushings, each said bushing being coupled to a respective said opposite end of the mirror holder;
- and
- a calibration switch having minimum proximity to the activation feature of the mirror holder.
A head up display mirror holding method for a motor vehicle, said method comprising:
- producing a light field;
- reflecting the light field such that the light field is visible to the driver as a virtual image;
- retaining the mirror by use of a mirror holder;
- activating a switch when the mirror holder is at a predetermined position;
- and
- in response to the activation of the switch, transmitting a feedback signal to calibrate and record the predetermined position in a memory device.
A head up display mirror holder arrangement for a motor vehicle, the arrangement comprising:
- a picture generation unit configured to produce a light field;
- a mirror configured to reflect the light field such that the light field is visible to the driver as a virtual image;
- a mirror holder having two opposite ends aligned along a rotational axis of the mirror, the mirror holder being configured to retain the mirror;
- a first bushing and a second bushing, each said bushing being coupled to a respective said opposite end of the mirror holder;
- and
- a bracket configured to couple the first bushing to a housing, the bracket including a mechanical stop configured to limit rotation of the mirror relative to the bracket.
