A chair action features a movable seat frame (11), a drive frame (12) for effecting seat frame movement, and an underpinning yoke frame (13), intervening pivot slides operative between frames, with guideway slots (14, 14, 16) and followers (19) variously in frames, to contrive a combined pivot swing and translational slide action, and free-floating seat frame mobility, whilst conforming to virtual pivot geometry; operable under a potential energy function in an inter-relationship between back recline and seat movement, for a common or harmonious experience between different occupancy weights |
