A tray table assembly capable of automatically deploying from a stowed position in a vehicular seat back towards a use position within a passenger compartment of a vehicle is provided. The assembly includes a support structure adapted to be coupled to the seat back, a tray support and a tray subassembly supported for rotation about a rotational axis by the tray support. A bi-directional, electrically-powered linear actuator subassembly is mounted on the support structure and includes a motor-driven screw-drive and a threaded member mounted on the screw-drive to linearly move along a longitudinal axis of the screw-drive upon rotation of the screw-drive. The threaded member is connected to the tray support to lift the tray support to deploy the tray subassembly along a predetermined non-linear path upon rotation of the screw-drive in a first direction from the stowed position to the use position based on a deployment command signal.
