1. A seat pan assembly, comprising:
- a fixed seat pan frame defining a substantially horizontal forward portion and a rear portion at an angle to horizontal; and
a seat pan pivotally supported on the fixed seat pan frame, the seat pan having a pivot axis established through a width of the seat pan such that the seat pan is free to pivot relative to the fixed seat pan frame between substantially horizontal and an angle to horizontal;
wherein a forward end of the seat pan directly engages the substantially horizontal forward portion of the fixed seat pan frame when the seat pan is substantially horizontal and a rearward end of the seat pan directly engages the rear portion of the fixed seat pan frame when the seat pan is at an angle to horizontal, and wherein the rear portion of the fixed seat pan frame dictates the seat pan angle to horizontal and the substantially horizontal forward portion of the fixed seat pan frame prevents the forward end of the seat pan from pivoting downward past substantially horizontal.

13. An aircraft passenger seat, comprising:
-
a fixed seat frame including parallel, spaced left-side and right-side rails each defining a substantially horizontal forward portion and a rear portion at an angle to horizontal; a seatback pivotally attached at one end to the fixed seat frame, the seatback configured to pivot relative to the fixed seat frame between upright and reclined positions; and a seat pan frame configured to pivot relative to the underlying fixed seat frame independent of pivoting motion of the seatback, the seat pan frame having a pivot axis established through a width thereof such that the seat pan frame is free to pivot relative to the fixed seat frame between substantially horizontal and an angle to horizontal; wherein a forward end of the seat pan frame directly engages the substantially horizontal forward portion of the fixed seat frame when the seat pan frame is substantially horizontal and a rearward end of the seat pan frame directly engages the rear portion of the fixed seat frame when the seat pan frame is at an angle to horizontal, and wherein the rear portion of the fixed seat frame dictates the seat pan frame angle to horizontal and the substantially horizontal forward portion of the fixed seat frame prevents the forward end of the seat pan frame from pivoting downward past substantially horizontal. - View Dependent Claims (14, 15, 16, 17, 18, 19)
