发明名称 HEATED STADIUM SEAT
摘要 A heated seat assembly especially suitable for outdoor use. A heater insert is positioned in the hollow of the seat cushion and includes a substrate member and a thin film heating element positioned on the substrate member. The heater insert is inserted into the hollow of the cushion through a slot in the rear edge of the cushion to position the thin film heating element within the hollow of the cushion beneath the seating surface. The heater insert is held in position by positioning of the forward edge of the substrate member in a crevice defined interiorly of the cushion proximate the front end of the cushion and by adhesive securement of a handle portion of the heater insert against an outer face of the rear edge of the cushion. Leads extend from terminals of the heating element to a plug in the handle portion of the insert which may be accessed by a plug of a pigtail cord extending from a junction box positioned on a riser surface of a grandstand immediately behind the seat assembly. Expanded foam is delivered into the hollow of the cushion beneath the substrate member to fill the area beneath the substrate member to discourage downward migration of heat generated by the heater insert and direct the generated heat upwardly to the seating surface. A similar heater insert is positioned in the seat back of the seat assembly and includes an exterior plug which may be connected by a further pigtail cord emanating from the junction box.
