ABSTRACT:
A display retract mechanism for moving a display between a retracted position and a deployed position is disclosed and explained. The display retract mechanism is useful, for example, in mounting a liquid crystal display within the cabin of a passenger vehicle, such as an aircraft or bus. A geared chain drive supplies torque necessary for rotating a pivot shaft on which the display is attached. The display is biased toward a retracted position by a gas spring with a substantially linear force curve between the retracted position and the deployed position. Also disclosed are an infrared sensor for detecting when the display is in the deployed position, a solenoid latch for holding the display in the retracted position, and an electromechanical clutch for maintaining the display in a particular position.
