US Patent 9643727 Airplane seatback tray table cover system

A sanitary airplane seat back barrier system with contiguous material forming a tray table cover, and contiguous material to form a seatback pocket protector and seatback cover. The components are packaged in a folded state to allow positioning as a sleeve on an airline tray table, providing complete coverage of the table with subsequent unfolding of contiguous material to reveal a seatback pocket protector and seatback cover. This creates a contiguous sanitary barrier for an airline tray table and the surrounding surfaces known to commonly have microorganism contamination.
