Abstract
Abstract A flexible unitary seat shell is disclosed to include: a base section defining a base section plane, the base section including two frame sockets for engaging, along axes that are substantially parallel to the base section plane, projections on a seat frame, each of the two frame sockets protruding from a back of said base section and including an encircling aperture that defines a plane that is nonparallel to the base section plane; a back section in angular relationship to the base section; and an intermediate section connecting the base section to the back section, the intermediate section forming a hinge between the base section and the back section to permit changes in the angular relationship between the base section and the back section.
