Abstract

L'invention porte sur une chaise comprenant un mécanisme de liaison à roulement-coulissement libre, laquelle chaise comprend un support (1), un dossier (2) et une plaque de siège (3), tous deux montés sur le support (1). Le dossier (2) et la plaque de siège (3) sont articulés entre eux, et le dossier (2) est relié de façon à pouvoir pivoter à un arbre fixe (4) sur le support (1). Au moins un moyen de roulement pour régler le mouvement vers l'avant et vers l'arrière de la plaque de siège (3) et des moyens de guidage correspondant aux moyens de roulement sont disposés entre la plaque de siège (3) et le support (1). La chaise peut réduire efficacement la force de frottement entre le dossier et la plaque de siège lorsque l'angle entre ceux-ci est réglé, de façon à la régler de façon plus pratique et plus souple et à éviter une détérioration des pièces.
