摘要： A shell chair construction comprising a shell of molded rigid polyurethane shaped to define seat and back portions in which the seat portion has applied to same a seat assembly comprising a contoured seat pan of plate like construction, to the upper side of which is applied seat padding covered by fabric material that is brought around the rim of the pan and stapled thereto on the underside of the pan. The pan carries spaced fastener elements made fast thereto for reception in correspondingly located holes in the shell seat portion to receive fastener screws that secure the seat subassembly and the chair iron in place on the chair shell. The shell includes compression inserts embedded in the shell portion through which the said shell seat portion holes are formed, and against which the seat pan is clamped by the fastener screws that make the seat assembly and chair iron fast to the chair shell. The seat pan defines a downturned marginal rim which is clamped against the shell seat portion by the action of the fastener screws, to clamp the seat padding covering fabric in place.
