ABSTRACT:
A headrest with a closed frame consisting of a U-shaped support piece with the two arms of the support piece connected by a crossbar. Two stay bars designed for insertion in a backrest extend from the frame. The frame is covered by a foam-filled, hose-like, protective covering which leaves a central opening in the headrest. The invention also pertains to a method for producing a headrest of this type. The U-shaped support piece is threaded through an opening in the protective covering. The crossbar is inserted into the opening in the protective covering and locked between the arms of the U-shaped support piece. The space between the U-shaped support piece and the crossbar and the protective covering is filled with the foam.
