ABSTRACT:
A head up display (HUD) mounting assembly (MA) enables the secure, yet flexible mounting of major HUD components within vehicles and particularly within the cockpit of an aircraft. Flexibility is desirable because of slight movement of airframe members during maneuvers and changing temperature and air pressure conditions, yet stability must be maintained in order to preserve optical alignment between the HUD projector and image combiner components. The inventive MA provides an integrated support for the HUD projector and image combiner thus improving optical stability over discretely mounted systems. The MA has a relatively rigid support arm attached to two end brackets, where one is a spring bracket and the other is an anti-twist bracket. The brackets are mounted to the ceiling of an aircraft cockpit to support the arm and to resiliently hold the HUD components in optical alignment.
