Abstract: A mount for adjusting a mounting plane is disclosed. The mount comprises a first adjustable device, a second adjustable device and a third adjustable device. A first intersection between the first adjustable device and the second adjustable device forming a first principal axis and a second intersection between the second adjustable device and the third adjustable device forming a second principal axis substantially perpendicular to the first principal axis. The first adjustable device, second adjustable device and third adjustable device rigidly coupled together. The first adjustable device is configurable to be adjusted in a first translational degree of freedom, and substantially constrain the first adjustable device in remaining translational degrees of freedom, wherein adjustment of the first adjustable device in the first translational degree of freedom causes a rotation of the mounting plane about the second principal axis.

Abstract: A combiner assembly for a ceiling mounted projection head up display system for an aircraft cabin has an optical combiner (10), and a support mechanism (30, 32, 35) for supporting the optical combiner to be movable between an operational position and a stowage position, above the user, and laterally displaced, and facing an underside of the projector assembly by means of a lateral component of movement and a rotation component to reach the stowage position under the projector assembly (20). Such a two axis movement can make better use of limited headroom in cabins such as those of small aircraft, by enabling a stowage location offset to one side of the line of sight, while providing sufficient clearance from the user's head and from cabin structure, during the movement and/or when in the storage position.

Abstract: A wearable head-up display which allows for convenient and safe stowage when not in use. A hinge component is positioned within the optical path from an image projector to a display component which ensures optical alignment for projection. A detection means is provided to signal when the wearable device is in a folded position in order to deactivate the projector.
