  • Patent number: 4181281
    Abstract: An articulated multi-swivel chair operable for access to stations disposed within a 360 degree circular range about the chair, includes a mechanism composed of at least two friction loadable pivots each supporting a corresponding link and, in combination, acting to support, with universal motion in two lateral axes, a chair body. Each of the pivots are preferably formed utilizing a tapered roller bearing or thrust bearing or bushing which are adjustable to provide a predetermined level of pivot friction by tightening an adjustment device such as an adjusting nut associated with each bearing. The first or lowest pivot is supported in a base which is of appropriate design to prevent tipping or which may be bolted or otherwise secured to the floor.To prevent pivot lock-up and provide shock absorbtion when the links are fully extended, repulsion devices are provided in the links.
