a seat pan plate having a front side, a rear side, a left side, a right side, a top surface, and a bottom surface; wherein the seat pan plate is configured to move between stowed and deployed positions;
a pair of beam braces configured to directly engage laterally-oriented portions of a seat frame of a seat bottom portion of a seat, wherein the seat includes the seat bottom portion and a seat back portion, wherein the laterally-oriented portions are perpendicular to the beam braces, and wherein the seat bottom assembly moves between stowed and deployed configurations independent of the seat back portion of the seat;
a pair of front links operationally connecting the beam braces and the seat pan plate;
a pair of rear links operationally connecting the beam braces and the seat pan plate;
wherein each of the front links is disposed on an opposite side of the seat pan plate from the other front link; and wherein each of the rear links is disposed on an opposite side of the seat pan plate from the other rear link; and
a seat cushion having a first top portion, a second top portion, and a bottom portion; wherein the bottom portion of the seat cushion is generally disposed on the top surface of the seat pan plate; wherein the bottom portion of the seat cushion and the seat pan plate are equally inclined when the seat pan plate is in the stowed and deployed positions; and wherein the second top portion is generally horizontal when the seat bottom assembly is in the deployed configuration, and negatively inclined relative to horizontal when the seat bottom assembly is in the stowed configuration.
