ABSTRACT:
A high density stacking chair having a unique construction permits interaction between a frame member and a chair shell. The frame member is formed of a unitary construction, and the chair shell is formed of a singled piece of molded plastic material. The chair shell includes a seat portion and a back portion joined integrally to the seat portion and extends upwardly therefrom. Fastening members are provided for securing the support straps joined to the frame member to the seat portion of the chair shell. Locking devices are provided for securing the support straps to the back portion of the chair shell. The locking devices define pivot points about which the back portion rotate outwardly when the seat portion of the chair shell is deflected forwardly and the back portion of the chair shell is deflected rearwardly so as to force outwardly under stress the frame member. The frame member including front and rear leg portions resiliently urge the chair shell back to its original position when the outward force is removed.
