A base for a chair, the base comprising a chassis (11), at least one landing (20) operatively connected to the chassis; a carrier (32) for reduced friction sliding along the landing transverse to the forward facing direction of the occupant; the carrier being adapted to support a pedestal (40) upon which the chair is operatively mounted. The base may include a foot rest (14), brake means (49) to prevent sliding when the seat is not occupied and wheels between the chassis and floor to permit movement of the seat transverse to the sliding of the carrier. The wheels may be lockable. The landing may comprise an inverted U channel in which rollers slide from which the carrier may suspend underneath the chassis.

L'invention concerne une base pour une chaise, la base comprend un châssis (11), au moins une barre d'appui (20) reliée de manière opérationnelle au châssis; un support (32) servant à réduire le frottement coulissant le long de la barre d'appui de manière transversale dans le sens frontal avant de l'occupant; le support étant adapté pour supporter un socle (40) sur lequel la chaise est montée de manière opérationnelle. L'assise peut comprendre un repose-pieds (14), un organe de frein (49) permettant d'éviter un glissement lorsque le siège n'est pas occupé et des roues placées entre le châssis et le sol pour assurer un mouvement du siège transversal par rapport au glissement du support. Les roues peuvent être bloquées. La barre d'appui peut comprendre un canal en U inversé dans lequel les rouleaux glissent et à partir duquel le support peut être suspendu sous le châssis.
