Abstract
A beam for a passenger seat has a hollow body including several spaced-apart frame mounting portions each defining a cross-section for being mounted to a seat frame. Seat portions are disposed between consecutive ones of the frame mounting portions and define a second cross-section for being mounted to a seat base disposed centrally below adjacent pairs of seat frames. The body is curved such that the seat portions are laterally downwardly offset from the frame mounting portions.
Claims20
A beam for a passenger seat, comprising:
- a hollow body having at least three spaced-apart mounting portions each defining a first cross-section for being mounted to spaced-apart seat frames, and at least two seat portions disposed between consecutive ones of said frame mounting portions and defining a second cross-section for being mounted to a seat base disposed centrally below consecutive ones of said seat frames, said body being curved such that said seat portions are laterally downwardly offset from said mounting portions.
A passenger seat frame assembly comprising:
- at least three spaced-apart seat frames, each of said seat frames defining a curved shape corresponding to the profile of an anatomically-appropriate seat bottom and defining a frame mounting point;
- at least one seat base for being attached to a supporting surface, each of said seat bases having a beam mounting point disposed centrally between and lower than said first and second frame mounting points;
- and
- a beam comprising a hollow body having at least three mounting portions spaced along the length thereof, each of said beam mounting portions defining a first cross-section, and at least two seat portions disposed between consecutive ones of said mounting portions and defining a second cross-section, wherein said body is curved such that said seat portions are laterally downwardly offset from said mounting portions, and wherein each of said mounting portions is attached to one of said seat mounting points and at least one of said seat portions is attached to one of said beam mounting points.
