Abstract
A seat pan includes a break over function. The break over enables downward motion of a portion of the seat pan. The downward motion of the portion of the seat pan allows a distance between passenger seats to be reduced while maintaining a minimum required egress distance between the passenger seats. The breakover seat pan assists in egress. The portion of the seat pan may be actuated upwards to increase the length of the seat pan while a passenger is seated. The seat pan thus creates a supported seat surface when an occupant sits on the seat while presenting with a reduced surface when not occupied.
