Abstract: A seating unit that includes a linkage mechanism adapted to move the seating unit between seat-lift, closed, extended, reclined, and seat-lift positions is provided. The linkage mechanism includes a seat-mounting plate mounted to a footrest assembly, a base plate fixedly mounted to a lift assembly, a back-mounting link rotatably coupled to the seat-mounting plate, a seat-adjustment assembly with a bellcrank, and a linear actuator for automating adjustment of the linkage mechanism. In operation, a stroke in a first phase of the linear actuator generates a force on the bellcrank that translates the seat-mounting plate rearward in a consistent angle of inclination and rotates the back-mounting link from a reclined to an upright orientation. A stroke in a second phase acts to collapse the footrest assembly. A stroke in a third phase causes the lift assembly to raise and tilt the seating unit, thereby accommodating egress and ingress of an occupant.
