ABSTRACT:
A reclining legless chair comprising an interlocking headrest constructed from a framework composed of a seat frame, back materials, and a headrest frame, which allows users to automatically set the inclining angle of the headrest which is interlocked to the angle between the seat and the back of the chair wherein the latter angle can be set in one of several steps at will by a user. The framework is made from a U-shaped seat frame, back materials and a headrest frame, in which both opening ends of the seat frame are connected to the straight rods of the back materials through a ratchet and the other ends of the rods are connected to both ends of a U-shaped headrest frame through interlocking mechanisms. The framework is suitably covered with elastic materials, is finished by covering the elastic materials with external cloth and permits the headrest frame to move interlockingly with the inclining angle of the back materials against the seat frame.
