Abstract: A mirror assembly deployment system of a display unit includes an imaging mirror and an extension link assembly coupled to the imaging mirror. The extension link assembly includes an extension spring coupled to a housing of the display unit. The deployment system includes a compression link assembly coupled to the extension link assembly, wherein the compression link assembly comprises a compression spring. The system also includes a fold mirror coupled to the compression link assembly. The extension spring is configured to at least partially unload when the imaging mirror is released from a recessed position to cause the imaging mirror to rotate to an at least partially deployed position. The compression spring is configured to unload when the extension spring at least partially unloads to cause the fold mirror to rotate from a recessed position to a deployed position.

Abstract: A friction hinge assembly for an imaging mirror of a display unit includes a mounting base coupled to a housing of the display unit. The mounting base comprises a longitudinal pin portion. The assembly includes a hinge member coupled to the imaging mirror. The hinge member is positioned substantially around the pin portion, and the hinge member comprises a support portion. The pin portion is configured to apply a friction caused by contact of the pin portion with the support portion of the hinge member. The hinge member is configured to rotate about the pin portion from a first position to a second position without the friction, and the hinge member is configured to rotate about the pin portion from the second position to a third position with the friction.
