Segmented beam aircraft passenger seat

A passenger seat frame assembly comprising:

• first and second spaced-apart seat frames, each of said seat frames defining a curved shape corresponding to a profile of an anatomically-appropriate seat bottom and defining first and second beam mounting points respectively;
• a seat base for being attached to a supporting surface, said seat base having a central beam mounting point disposed centrally between and lower than said first and second beam mounting points;
• and
• a beam comprising a hollow body having a first end defining a first cross-section, a second end defining a second cross-section, and a central portion disposed between said first and second ends and defining a central cross-section, wherein said body is curved such that said central portion is laterally downwardly offset from said first and second ends, and wherein said first end is attached to said first beam mounting point, said second end is attached to said second beam mounting point, and said central portion is attached to said central beam mounting point.
