Claim Text:
1. 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 that rests on an underlying surface; 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 first linear actuator that provides automated adjustment of the seating unit between the closed position and the seat-lift position, wherein the first linear actuator is configured to move the lift assemblies into and out of the seat-lift position while consistently maintaining the seat-mounting plates inside a footprint of the lift-base assembly; and a second linear actuator that provides automated adjustment of the seating unit between the extended position, the reclined position, and the closed position, wherein in the reclined position, the backrest is reclined and the footrest assembly is extended, wherein in the extended position the backrest is inclined and the footrest assembly is extended, and wherein in the closed position the backrest is inclined and the footrest is retracted.
