Patent ID: 8113573

Claim:
A seat articulation mechanism, comprising: first and second seat pan members each having first and second opposed ends and including a seat pan roller positioned about the second end of the first and second seat pan members; first and second seat pan articulation linkages each defining an articulation control pathway along which the seat pan rollers travel as the seat articulation mechanism translates between an upright and a sleeping configuration through a lounge configuration; first and second main translation linkages pivotally connected to the first and second seat pan members, the first and second seat pan articulation linkages, and first and second stationary frame members, respectively; first and second secondary translation linkages pivotally connected to the first and second seat pan articulation linkages and the first and second stationary frame members; and an actuator for driving the motion of at least one of the first and second main and secondary translation linkages to drive the mechanism between the upright and sleeping configurations through the lounge configuration.
