Fundamentals of Chair guidance systems. The heart of the system is a high precision rail guiding a sled, both mounted in a cuboid-like housing. As the rail is mounted on the angular-milled surface, the sled is forced by gravity to return to its intended position. To avoid placing undue tension on the moving sled, only one rail is used. To solidly connect the chair leg socket to the carriage sled, it is sufficient to simply stick the stem into the conical aperture and fix it with a screw.
The chair - either with fixed leg or multifunctional leg with integrated twist mechanism - can now be mounted onto the chair leg socket. A special feature of this multifunction leg is the height adjuster and the twist mechanism that always rotates back to its starting position as the seat moves back to its initial position.
The chair guidance system is being mounted on a firm ground like a steel construction, concrete or wooden floor. Usually an adapter plate is used between the floor and the chair system. The solid aluminium housing lines up precisely with the floor and is closed with a magnetic cover plate. It is possible to use a designed cover plate or to cover the plate with the flooring like carpet or veneer.
