Abstract
An aircraft seat frame including a seat back portion, a seat foundation portion, and a seat base portion, the seat back portion having a pair of generally vertically disposed side rails composed of three interconnected segments, a leading and a trailing edge segments of which are perpendicularly disposed on opposing sides of an interior segment, thereby substantially minimizing an overall weight of the side rails and maximizing the side rails resistance to horizontal bending across a plane of the leading and trailing segments. Further, the seat frame includes a load transference member spanning the side rails so as to evenly distribute a load exerted on only a single of the side rails over both side rails and over the corresponding seat side rails to which the seat back side rails are connected. Further, the frame includes a seat base portion having a pair of seat side rails with support members pivotally secured at opposite ends thereof, the support members being fixedly secured to an underlying support surface.
