Patent ID: 8727433

Claim:
A seating unit having a chassis, a seat, a backrest, and at least one foot-support ottoman, the seating unit being adapted to move between a closed, an extended, a reclined, and a seat-lift position, the seating unit comprising: a lift-base assembly; a pair of base plates in substantially parallel-spaced relation; a pair of lift assemblies, wherein each of the lift assemblies is attached to a respective base plate and raises and lowers the respective base plate directly above the lift-base assembly; a pair of seat-mounting plates in substantially parallel-spaced relation, wherein the seat-mounting plates suspend the seat over the lift assemblies; a pair of generally mirror-image linkage mechanisms each moveably interconnecting each of the base plates to a respective seat-mounting plate, wherein each of the linkage mechanisms comprise: a footrest assembly that extends and retracts the at least one foot-support ottoman; a cam control link that includes a front end and a rear end, wherein the front end of the cam control link is pivotably coupled with the footrest assembly; a sequence cam that includes a contact edge and is rotatably coupled to the seat-mounting plate, wherein the rear end of the cam control link is pivotably coupled to the sequence cam; and a sequence element extending outwardly from a respective linkage mechanism; and a linear actuator that provides automated adjustment of the seating unit between the closed position, the extended position, the reclined position, and the seat-lift position, wherein the contact edge of the sequence cam engages the sequence element in the closed position to maintain the seat-mounting plates inside a footprint of the lift-base assembly when adjusting to the seat-lift position.
