Abstract
Abstract Seat back tray table is pivotally mounted to the frame of a seat, and preferably an aircraft passenger seat, so as to be stowable in a recess in the back of the seat but easily movable to a horizontal use position. The table is formed in two hinged sections including an outer thicker section which is fixed to a pair of side support frame members and an inner thinner section which can be pivoted 180* toward the seat back to be supported by the side support frame members in their horizontal use position. The compact table provides more passenger knee room than nonfolding prior art tray tables and also permits the table assembly to be of less weight since the pivoted portion of the table would not be expected to receive the loading applied to the fixed table portion which is more accessible to a seat occupant.
