Abstract

L'invention concerne une chaise pliante comprenant des tiges de dossier (1), une poignée de préhension (2), des tiges de traction supérieures (3) et des éléments télescopiques (4). Une extrémité de chaque tige de traction supérieure (3) est disposée de manière rotative au niveau de la portion supérieure de chaque tige arrière (1), et l'autre extrémité de chaque tige de traction supérieure est disposée de manière rotative sur la poignée de préhension (2). Une extrémité de chaque élément télescopique (4) est disposée de manière rotative sur la poignée de préhension (2), et l'autre extrémité de chaque élément télescopique est disposée de manière rotative au niveau de la portion inférieure de chaque tige arrière (1). Deux tiges arrière (1), deux tiges de traction supérieures (3) et deux éléments télescopiques (4) sont disposés symétriquement sur les côtés gauche et droit de la ligne centrale de la poignée de préhension (2). La tige arrière gauche (1) et la tige arrière droite (1) forment le dos de la chaise pliante. Les éléments télescopiques (4) comprennent des tiges télescopiques (41) et des manchons télescopiques (42) et, lorsque la chaise pliante se trouve dans un état déplié, les éléments télescopiques (4) sont à la longueur la plus courte. Dans la chaise pliante, le dossier de la chaise pliante peut être efficacement déplié et plié ; et lorsque la chaise pliante se trouve dans l'état déplié, chaque composant mobile se trouve dans dans un état protégé et n'est pas perturbé par l'environnement externe, de sorte que la structure globale est plus stable et le taux de défaillance est réduit.
