US Patent 7201438 Two-position arm chair

A chair has a frame, a seat on the frame, a back on the frame, and a link between the seat and the back for shifting the seat and back between a sitting position with the back generally vertical and the seat generally horizontal and a relaxed position with the back less vertical and the seat shifted forward on the frame. A pivot defines a horizontal pivot axis carrying the headrest for pivoting between a generally horizontal position extending rearward from the pivot axis and an erect position extending upward from an upper end of the back. A linkage connected between the headrest and the back pivots the headrest about the axis into the erect position on shifting of the back and seat into the relaxed position and pivots the headrest about the axis into the horizontal position on shifting of the back and seat into the sitting position.
