Abstract
A head-pan diaphragm structure attachable to or an integral part of a seat back structure, the head-pan diaphragm structure including high-performance fibers and the head-pan diaphragm structure positionable in a head strike target area of the seat back structure. A seat back assembly including a seat back frame member including spaced portions, a torsion bar attached between the spaced portions, a head-pan diaphragm structure positioned in a framed opening formed by the torsion bar and a portion of the seat back frame member, the head-pan diaphragm structure positioned in a head strike target area, and the head-pan diaphragm member including integrated high-performance fibers.

1-5. (canceled)
A seat back assembly, comprising:
- a continuous perimeter frame including spaced apart side members and an interconnecting top member;
- a torsion bar attached to and extending between the spaced apart side members at a predetermined position spaced apart from the interconnecting top member to divide the seat back assembly into a upper portion above the torsion bar corresponding to a headrest portion of the seat back assembly and a lower portion below the torsion bar corresponding to a backrest portion of the seat back assembly;
- and
- a head-pan diaphragm structure filling a framed opening of the upper portion, the head-pan diaphragm structure positioned in a head strike target area on a backside of the upper portion, and the head-pan diaphragm member including integrated high-performance fibers.
An aircraft passenger seat assembly, comprising:
- a seat frame assembly;
- a seat pan attached to the seat frame assembly;
- and
- a seat back pivotally attached to the seat frame assembly, the seat back including:
- i) a U-shaped frame member including spaced apart side members and an interconnecting top member;
- ii) a torsion bar attached to and extending between the spaced apart side members at a predetermined distance spaced apart from the interconnecting top member to divide the seat back into an upper portion above the torsion bar corresponding to a headrest portion and a lower portion below the torsion bar corresponding to a backrest portion;
- and
- iii) a head-pan diaphragm structure mounted within and filling a framed opening of the headrest portion, the head-pan diaphragm structure including high-performance fibers.
