Abstract
Examples provide a door assembly including a dual operation slide device for a sliding privacy door associated with a seat unit. The door assembly includes a sliding door movably mounted to a door support member of a seat unit. The door slides laterally between a retracted position and a deployed or partially deployed position. The dual operation slide device includes a trigger and release mechanism for switching the door assembly from a primary track system used during a normal operation mode to a secondary track system used during a backup operation mode if the primary track becomes jammed or otherwise malfunctions based on manual activation of a release lever or force applied activation. The dual operation slide device enables a user to return the sliding door to a retracted position after a failure of the primary slide units to operate in the normal operational mode.
