ABSTRACT:
The present invention generally relates to a force dissipation seat pedestal that is particularly useful in aircraft seat design. The seat includes two rear supports having multi-strip legs, two front supports having unibody legs, and two gussets located proximal the front legs. One end of each leg is pivotally secured to the pedestal. An other end of each leg is pivotally secured to the floor of the aircraft via a hinged floor mount assembly. The front and rear supports and gussets are designed to maintain their shape during normal operation of the aircraft, but to deform during an emergency landing to reduce the forces transmitted to an occupant of the aircraft seat.
