1. An aircraft seat pan assembly, comprising:

  • left and right spreaders;

    a seat pan including left and right seat pan members each pivotably attached proximate a forward end to the left and right spreaders and free of attachment at a rearward end to the left and right spreaders such that the left and right seat pan members are configured to pivot to adjust seat pan angle;

    a first transverse beam interconnecting the left and right spreaders;

    a second transverse beam interconnecting the left and right seat pan members;

    a third transverse beam arranged to travel along guide slots of the left and right spreaders;

    a link interconnecting the second and third transverse beams; and

    a gas spring connected between the first and third transverse beams;

    wherein seat pan recline in response to passenger body weight drives the third transverse beam toward the first transverse beam to compress the gas spring, and removal of passenger body weight from the seat pan causes the gas spring to unload to drive the third transverse beam apart from the first transverse beam to assist in returning the seat pan from a reclined position to an upright position.
