A chair particularly useful for an auditorium utilizes spherical bearings (22) to mount the seat bottom (18) of the chair to uprights standards. The spherical bearing (22) includes a first race portion (20) integral with the bottom of the chair and a removable cap portion (24) that is secured to the chair bottom to hold the spherical bearing. An axle (28) extends through each standard to engage the bearings to support adjacent chairs. The axles are threaded to receive a nut to secure the axles to the standards.

L'invention porte sur un siège qui convient particulièrement pour un auditorium, et pour lequel des roulements à rotule sont utilisés pour fixer le fond du siège à des tiges verticales. Un roulement à rotule comprend une première partie de roulement formant bloc avec le fond du siège, et une partie capuchon rattachée au fond du siège pour retenir le roulement à rotule. Chaque tige est traversée d'un axe qui entre en prise avec les roulements pour servir de support à des sièges adjacents. Ces axes sont filetés pour recevoir un écrou servant à fixer les axes aux tiges.
