Abstract (en)
[origin: WO0238010A1] A collapsible chair (10) has a first (110) and second (112) front leg, a rear leg (120), a seat support rod (130), and a backrest is attached to the front legs. The legs and the seat support rod are coupled via cross braces (140, 150) such that the seat support rod pivots in one direction while the rear leg pivots in the opposite direction when the front legs are approximated to each other. Preferred chairs comprise a seat that is tensioned when the front legs move apart, and the seat remains substantially tensioned when the seat supports a person.
