Abstract: Described is a frame component for a passenger seat assembly. The frame includes a tubular frame component having a first portion and a second portion. The bent portion bends the frame at a non-zero angle within a plane. The tubular frame component includes a variable inner diameter such that the first portion of the tubular frame component has a first wall thickness and the bent portion of the tubular frame component has a second wall thickness that is different from the first wall thickness.

Abstract: A passenger seat includes a seat frame, a plurality of legs extending down from the seat frame where each of the plurality of legs includes an upper end attached to the seat frame and a lower end, and at least one tube attached to the lower end of at least one of the plurality of legs. The at least one tube includes at least two attachments to a floor structure. The at least one tube includes at least one bent portion.

Abstract: Described are passenger seat bottom assemblies that include a layered seat bottom assembly formed of a first face sheet, a lightweight core layer, and a second face sheet bonded together, preferably in a flat or substantially flat arrangement. The core layer can be a honeycomb structure, e.g. a metal or aluminum honeycomb, or a foam, that confers a high strength and stiffness to the seat bottom assembly with minimal forming and minimal weight.

Abstract: A system for securing a passenger seat to a track can include a fitting coupled with or forming a portion of the passenger seat; a shear plunger coupled with the fitting including a shear plunger body defining a shear plunger locking surface; a guide pin assembly that may include a guide pin movable along a lift axis between a retracted state and an extended state and a locking member extending laterally from the guide pin that may travel in response to a movement of the guide pin from the retracted state to the extended state and may engage the shear plunger locking surface in response to a rotation of the guide pin in the extended state; and a quick install tool operable to raise and twist the guide pin assembly such that the locking member is held in tension against the shear plunger locking surface.

Abstract: Described are seat backs for passenger seats. The seat back includes a frame, and the frame includes an upper portion and a lower portion. The upper portion includes a top end of the seat back, and the lower portion is adjacent to the upper portion. A thickness of the upper portion of the frame may be less than a thickness of the lower portion of the frame.
