Tiltable chair, including a seat structure (18) for supporting a person; a seat carriage (24) on which the seat structure (18) is mounted for tilting about an essentially horizontal first axis; a base structure (12) on which the seat carriage (24) is mounted for linear movement between two end positions along a second axis substantially perpendicular to the first axis; and means (26) for coupling tilt movement of the seat structure (18) and linear movement of the seat carriage (24) whereby the center of gravity of a person when seated in the seat structure (18) upon its tilting will remain substantially fixed at a point in space or within a small locus thereof through linear movement of the seat carriage (24) on the base structure (12). The means for coupling the two movements preferably comprises a mechanical gear (261, 262, 263 and 264) facilitating construction and synchronization of both movements. |
