1. A multi-position chair assembly permitting the support and comfort of a user thereof, in a plurality of sitting positions, comprising:

  • a lower chair support panel attached to an adjustable tilt support mechanism, which adjustable tilt support mechanism is carried by a vertically maintained hub; and

    a frame attached to said hub for supporting a chair back support panel;

    said back support panel being pivotably attached to said frame to permit tilting of said back support panel relative to the center of gravity of a user of said chair assembly with respect to said adjustable tilt support mechanism under said lower support panel;

    said lower support panel and said back support panel being connected by a single pair of slidable pivotable linkages which effects pivoting of said back support panel about a horizontal axis when said lower support panel is tilted about said adjustable tilt support mechanism;

    said back support panel including a lowermost member having a carrier pin extending transversely from each corner thereof, and said lower support panel having a frame with a slot therein adjacent its rearward edge, each said carrier pin being in a cammed slidable linkage relationship with said slot to effect said single slidable pivotable linkage correction between said lower panel and said back support panel; and

    an arm rest disposed on each side of said chair assembly, said arm rest being pivotably connected at an upper end thereof, to said back support panel, and being pivotably connected at a lower end thereof, to said lower support panel, to permit limited articulation between said back and lower support panels and said arm rests.
