Abstract: 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 (30, 430, or 530) is fastened to the upper end portion of the pedestal assembly (14). A connector, in the form of a primary seat spring (40), or a rigid, connecting plate (513), is secured to the support (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 (30, 430 or 530). The interactive spring (60 or 660) extends outwardly from the support (30, 430 or 530) in generally parallel relation with the connector (40 or 513) to be disposed in a cantilevered fashion therebetween.

Abstract: The present invention is directed to a suspension mechanism (10) utilized to interconnect the seating portion (16) as well as the back supporting portion (18) of a chair assembly (12) to a pedestal assembly (14). A spring support (30) is fastened to the upper end portion of the pedestal assembly (14). At least one primary seat spring (40) is secured to the spring support (30) and extends generally upwardly and rearwardly therefrom to be secured to the underside of a seating portion (16). Preferably, the primary seat spring (40) comprises a pair of laterally spaced, leaf springs (40). Also secured to the spring support (30), and preferably between the pair of laterally spaced primary seat springs (40), is an interactive spring (60). The interactive spring (60) extends outwardly from the spring support (30) in generally parallel relation with the primary seat springs (40) to be disposed in a cantilevered fashion therebetween.
