ABSTRACT:
A video monitor is deployed from an aircraft overhead storage compartment via a monitor-drive shaft selectively connected to an electric motor and retracted back into the compartment by a spring connected to the shaft. The monitor has limited rotational movement in both directions relative to the shaft. A bump sensor detects when the monitor has moved from its deployed position relative to the shaft as a result of being struck by a passenger and trips a solenoid. The solenoid, in turn, disengages the monitor-drive shaft from the motor and allows the spring to return the monitor to its stores position.
