Abstract

La chaise pliable (10) possède un siège (12) et plusieurs paires d'entretoises (20, 22, 24, 26, 28, 30, 32, 34) reliées de manière pivotante au niveau de leurs points médians. Les entretoises possèdent des extrémités aplaties. Les paires d'entretoises sont reliées de manière pivotante par plusieurs éléments de connexion (36) suivant une configuration en bout-à-bout pour former une structure en treillis sans fin. Le siège (12) est rattaché aux éléments de connexion (36) semblables le long d'un bord supérieur de la structure en treillis. La chaise pliable est mobile entre un état replié dans lequel les extrémités des éléments sont rapprochées et sollicitées les unes vers les autres en resserrant et comprimant les entretoises et le siège, et un état ouvert ou déployé dans lequel le siège (12) empêche les extrémités de s'écarter afin de présenter une surface d'assise. Chaque connecteur (36) possède une fente de réception d'une extrémité des éléments et un rivet est utilisé pour coupler le connecteur dans la fente. Les éléments possèdent une section médiane décalée et aplatie de sorte que leurs extrémités se déplacent pratiquement dans le même plan de rotation par pivotement lorsque la chaise passe d'un état replié à un état déployé.
