Retractable holographic combiner

A retractable holographic combiner comprising a movable holographic mirror positioned in front of a user, wherein said holographic mirror presents light images collimated to infinity, said light images being superimposed over an external image and originating in a projector disposed upstream of said combiner, said holographic mirror being connected to an immovable portion of a vehicle in which said combiner is disposed by an articulated support for holding and positioning said holographic mirror, said articulated support comprising:

• a single lateral connecting arm, said connecting arm comprising a first hinge connecting a first end of said arm to said immovable portion of said vehicle, and a second hinge connecting said arm at a second end to a lateral side of the holographic mirror, said first and second hinges being positioned such that an axis of rotation of said first hinge is parallel to an axis of rotation of said second hinge, said axes of rotation of said first and second hinges being perpendicular to a longitudinal axis of said arm;
• said second hinge being adapted to provide retraction of said articulated support by rotation of the holographic mirror about said second hinge of said arm, wherein said rotation is performed prior to, or simultaneously with, rotation of said arm about said first hinge;
• and
• a manipulating handle for manually adjusting a position of said holographic mirror, wherein said manipulating handle is adapted to be operated using only one hand, said manipulating handle being connected to said holographic combiner.
