ABSTRACT:
A passenger seat leg assembly with an energy absorbing zone. The seat includes fore and aft located legs for being fastened to a seating track mounted on a floor and fore and aft located seat-bottom support for supporting a seat bottom assembly including a cushion. The seat legs and the seat bottom supports are integrally formed with each other to define a unitary seat leg assembly. The seat leg assembly is characterized in that the fore located leg and the fore located seat bottom support diverge from each other to define an intermediate concavity and includes an integrally-formed, peripherally enclosed and laterally-extending through chamber formed in the area of the concavity to define an energy-absorbing zone. An auxiliary crush-resisting member having predetermined magnitude of resistance to crushing cooperates with the chamber to provide additional resistance to crushing. The member may be a cover plate positioned over the chamber, inserts of various designs positioned within the chamber, or both. The chamber may have two lobes, one of which holds the insert and the other of which provides an expansion zone for the insert to occupy as it is crushed.
