Abstract
An aircraft seat frame including a seat back portion, having a pair of side rails secured to a seat foundation portion so as to transfer a load thereto, the seat foundation portion coupled to a seat base portion that is substantially strong so as to resist yielding. The seat base portion includes a pair of base rails having mount segments extending downwardly therefrom for coupling to an underlying support surface, and at least one spar rail secured between the base rails. The base rails also include an upper edge, a lower edge, and an interior base segment, each having a flat, planar configuration, with the upper edge base segment disposed at a top edge of the interior base segment in perpendicular relation thereto and the lower edge base segment disposed at a bottom edge of the interior base segment in perpendicular relation thereto, so that the upper edge, lower edge, and interior base segments are disposed to maximize a resistance of the base rail to vertical bending across a plane of the upper and lower edge base segments, while minimizing an overall weight of the base rails. Further, the base rails and spar rail are structured to be coupled to one another to define a pluralit…
