Abstract: A spreader and leg assembly for the base frame of an aircraft passenger seat including spaced saddles on the spreader and spaced stirrups on the leg assemblies that encircle a plurality of quadrants of the stretcher tubes to form a base frame.

Abstract: A saddle assembly for securing an aircraft seat to a seat leg assembly wherein the seat leg assembly has a pair of elongated openings and a chamber formed therein. A compression tube extends through the chamber formed in the seat leg such that opposite ends of the tube extend outwardly to be engaged by a pair of slide blocks mounted on opposite sides of the leg. A saddle, having spaced legs, supports the pair of slide blocks adjacent end portions of the compression tube such that an upward force on the saddle moves the slide blocks into engagement with opposite ends of the compression tube for dissipating energy.

Abstract: A seatback fitting assembly is provided with means to allow the complete forward rotation of the seatback, while remaining anchored to the seat structure, upon an excessive dynamic load or force impact on the seatback. This is accomplished by the use of a structural "breakover" device operating within the fitting assembly, which restrains the seatback within a limited, "forward tilt" range of motion under normal conditions, but allows complete forward rotation once load forces above an allowable level act on the seatback to cause a restraining pin to shear. A friction brake or clutch arrangement is provided to inhibit tilting of the seatback at all times but does not prevent the complete forward rotation of the seatback.
