Abstract
A display unit that rotates a video monitor between a stowing cavity and an exposed position so that viewers can see the monitor. The monitor is attached to a frame which is typically mounted into the ceiling of the passenger cabin of an airplane. Also attached to the frame is an electric motor that rotates the monitor into the stowed and exposed positions. Attached to the output shaft of the electric motor is a slip clutch that allows the monitor to rotate up from the exposed position when a predetermined force is applied to the viewing device. A spring is operatively connected to the monitor and electric motor, that pulls the monitor up into the stowed position if the electric motor becomes disabled. An electric brake is also attached to the output shaft of the electric motor to hold the monitor in the exposed position.
