A beam-mounted, foldaway chair. The seat tips up, the back reverts to an upright position and the armrests fold up out of the way in a single, automatic movement. The seat tips up about its axis while the backrest moves forward until they are flat against one another. When folded away, the depth of the seat and backrest together is 245 mm (9.7”). As the seat and backrest fold away, the armrests rotate into an upright position within this 245 mm space (9.7”). The sequence of movements described here occurs automatically whenever the seat is vacated. The folding mechanism relies on gravity and involves no springs. Furthermore, the application of the SOFT SYSTEM cushions the closure of the seat. This ensures maintenance free, extended durability. Cast aluminium sides, with polished or powder epoxy paint finish, support the seat, back and armrest assembly. The seat and back pivot on polyamide bushings that require no maintenance. The seat and backrest consist of two moulded polyurethane blocks about an internal structure and upholstery without any seams or stitching that is fully integrated with the foam by means of the INTEGRAL FORM system. Between the upholstery and the foam of both the seat and the back, there is a 5 mm-thick TS System fire curtain that prevents fire reaching the foam, thus preventing down the emission of toxic gases and flames. The sides supporting the seat and back are attached to a rectangular aluminium tube structure. The underneath of this structure is in turn attached to a foot made of aluminium tube that ends in a circular base that is anchored to the floor by means of metal expansion plugs. The structures come in modules of 2, 3 or 4 seats with a 70-80 micron black epoxy paint finish. Curved rows can be formed by joining several beams, each at a slight angle from the last. The seat has holes at the rear to ensure appropriate acoustic absorption when it is tipped up and not in use. In conjunction with the F-45 table or F-1000 table, this is an ideal solution for long working sessions and conferences.
