Abstract

A stackable chair has a frame with a tubular crosspiece (18), to each end of which a monolithic casting (FC) having a leg (12l, 12r, 14l, 14r) and a backrest support (16l, 16r) - and, optionally, armrests (122l, 122r) - is attached by means of an integral connecting boss (100) received within the crosspiece and held in place by a connector pin (30).
The backrest supports receive a backrest (50) that pivots about a pivot pin (62) between an upright position, to which it is biased by a spring (54), and a rearwardly tilted position. The range of tilting motion is limited by a stop pin (68) on the backrest and a stop groove (64) in the backrest support. A seat (24) is mounted on the crosspiece, either in a fixed position or for tilting to an upright position. Chairs with tilting seats include seat supports (28) having diametrically opposite slots (38, 40) that receive projecting portions of the connecting pins. The connector pins slidably engage the sides of the slots to hold the seat supports in place on the crosspiece axially.
The ends of the slots engage the connector pins in the down and tilted-up positions of the seat.
