A chair is formed from two side frame sections each including a tubular frame and leg assembly with expanded metal secured to it. The side sections are encapsulated in foam which adheres to and completely encompasses the expanded metal. A seat cushion and foamed front skirt are added to the foamed side frame sections. A flat skirt is provided to completely follow the periphery of the chair just above the floor; and two chairs may be joined at any desired orientation relative to each other by a doubly-grooved joinder member coupling the lower peripheral metal skirts together.

Seating furniture

A seating system having a number of rows which may be extended for use or retracted for storage is provided with individual chairs. As each row is moved forwardly relative to the next higher row, the chair backs pivot to the upright or use position where they are latched. As each row is moved rearwardly relative to the next higher row, the latches holding the chair backs in the use position are released and the chair backs are engaged by the deck of the next higher row to fold the chair backs downwardly and forwardly to the closed or storage position so that they may be stored in the space between adjacent decks.

Telescoping seating system with automatically folding chairs

A flame-resistant cushion includes a frame, an inner core of foamed polyurethane material carried by the frame, and an exterior layer of foamed neoprene bonded to and completely covering the entire surface area of the top, front, back and both sides of the core material. A metal pan is also secured to the seat frame to enclose the bottom of the cushion. In making the cushion, a latex water emulsion of neoprene is foamed and deposited in a thin layer on a carrier sheet. This composite lines a mold with the foam side engaging the mold; and unreacted polyurethane foam is poured into the mold. The adhesive properties of the polyurethane cause it to bond to the carrier sheet as it gels forming an integral cushion material with a covering of neoprene for greater fire resistance.
