ABSTRACT:
To permit use of injection-molded plastic parts in chairs which, otherwise, have a wide variety of coverings or shapes of the seats and/or the chair backs, the seats and chair backs are upholstered with material such as fabric or leather or imitation leather in accordance with selected colors, and made in shapes determined by designers; the back of the chair, and where the coverings are attached to a chair core (45), typically of plywood or the like, is then covered by injection-molded plastic shells or panels (51, 54) which can be snap-in attached by an interengaging attachment means to support brace (27) for the chair back, which support brace may form part of a synchronous seat-back tilting mechanism (15). The seat adjustment tilting mechanism (15) can be identical for any numbers of seats or chair backs, of respectively different shapes (FIGS. 3, 4, 5, 6), thereby permitting inexpensive modular construction and reducing stocking requirements for spare parts.
