FLEXIBLE HEADREST ASSEMBLY

Described are passenger seat headrest assemblies and seats including head-rest assemblies having a semi-rigid flap fixedly connected with an upper portion of the seat back or headrest assembly at a first location and movably connected with the seat back or headrest assembly at a receiving element separated from the first location. The distance of the movable connection from the first location can be adjusted to cause the flexible head-rest assembly to flex outward from the seat to provide a greater or lesser degree of support for a passenger.
