Abstract

L'invention concerne un châssis de chaise pivotante comportant un couvercle supérieur (1), un couvercle inférieur (2), et un ressort en caoutchouc disposé dans un espace formé par le couvercle supérieur et le couvercle inférieur. Le ressort en caoutchouc comporte un arbre principal (3), une couche de caoutchouc (4) étant disposée de manière fixe le long de la circonférence sur l'arbre principal (3), et un logement cylindrique (5) entourant de manière fixe la couche de caoutchouc (4). Le logement cylindrique (5) comporte un tenon de raccord (6), le tenon de raccord (6) étant raccordé à une extrémité d'une tige de raccord (11), et l'autre extrémité de la tige de raccord (11) pénétrant dans le couvercle supérieur (1) et étant raccordée à un bouton de réglage (12). Le châssis de la présente invention adopte un ressort en caoutchouc servant d'élément central. Deux extrémités de l'arbre principal (3) du ressort en caoutchouc sont raccordées sur un dossier par le biais de la tige de raccord, et quand une personne prend appui contre le dossier, le dossier exerce une certaine force sur l'arbre principal (3) par le biais de la tige de raccord pour entraîner l'arbre principal (3) à tourner selon un certain angle de rotation, et le logement cylindrique (5) du ressort en caoutchouc est fixe et immobile, de sorte que la rotation de l'arbre principal (3) permet à la couche de caoutchouc de générer un couple. Un plus grand angle de rotation de l'arbre principal (3) donne lieu à un plus grand couple. Le couple peut entraîner l'arbre principal (3) et le dossier à restaurer les positions de ceux-ci, pour ainsi permettre le réglage de n'importe quel angle.
