The present invention is directed to a suspension mechanism (10, 310, 410, 510 and 610) utilized to interconnect the seating portion (16) as well as the back supporting portion (18) of a chair assembly (12, 312, 412, 512 or 612) to a pedestal assembly (14). A support means (30, 430 or 530) is fastened to the upper end portion of the pedestal assembly (14). A connecting means, in the form of a primal seat spring (40), or a rigid, connecting plate (513), is secured to the support means (30, 430 or 530) and extends generally upwardly and rearwardly therefrom to be secured to the underside of a seating portion (16). An interactive spring (60 or 660) may also be secured to the support means (30, 430 or 530). The interactive spring (60 or 660) extends outwardly from the support means (30, 430 or 530) in generally parallel relation with the connecting means (40 or 513) to he disposed in a cantilevered fashion therebetween. The back supporting portion (18) may include a back cushion assembly (102) that is structurally carried by a stanchion (90, 390, 490, 490 or 690) that may be fixedly, or pivotally, secured to the seating assembly (16). When the stanchion (90, 390, 590 or 690) is pivotally mounted, a follower (130) may be presented from the stanchion (90, 390, 590 or 690) operatively to engage the interactive spring (60 or 660). A main back spring (140) may also be secured to the stanchion (90 or 590) to interact against the undersurface (146) on the seating pan (72) of the seating portion (16). One or more lock-out assemblies (150) may be utilized to effect immobilization of the back supporting portion (18) with the seating portion (16) and/or the seating portion (16) with respect to the pedestal assembly (14) if those components are not permanently affixed to each other or are not manually adjustable with respect to each other.
