Abstract:
1. A seat back, comprising an integral sheet material having a front and a back and having a top, a bottom, a pair of side edges, and a center portion between the side edges, the sheet material having rigidity sufficient to maintain a shape in an absence of a deforming force, the sheet material having side portions extending from proximity to respective side edges at least part way toward the center portion, the side portions curved concave relative to a forward direction from an area proximate the center portion toward the respective edges, the sheet material having upper and lower portions considered in a direction from the top toward the bottom, an area of the sheet material approximately at a juncture of the upper and lower portions protruding more forwardly than the major extent of the upper and lower portions, the sheet material being resiliently flexible to permit limited deformation during use generally in a prescribed manner in response to force applied thereto by a user tending to bend the upper portion of the sheet material relative to the lower portion of the sheet material in a direction front to back while supporting the back of the user, wherein such force causes the upper portion of the sheet to deform from concave relative to a forward direction from an area proximate the center portion toward the respective edges to convex relative to the forward direction from an area proximate the center portion toward the respective edges, and a mounting support that is more rigid than the resiliently flexible sheet material, the mounting support attached to the back of the sheet material in proximity to the respective side edges.
