Abstract:
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 for supporting the seating unit on underlying surface; a pair of base plates in substantially parallel-spaced relation, wherein each base plate includes a tubular portion, a first plate coupled to a forward portion of the tubular portion, and a second plate that is coupled to a rearward portion of the tubular portion; 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 and wherein each seat-mounting plate is attached to a respective second plate of a respective base plate; 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, the extended 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 maintaining the linkage mechanisms in the closed position and 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 and the reclined position.
