Abstract
A seating unit that includes a linkage mechanism adapted to move the seating unit between closed, extended, reclined, and seat-lift positions is provided. The linkage mechanism includes a footrest assembly, a back-mounting link coupled to a seat-mounting plate, a base plate coupled to a lift-base assembly via a lift assembly, a motor tube, and two linear actuators for automating adjustment of the linkage mechanism. A first phase involves a second linear actuator rotating the motor tube angularly within a first range of degrees, causing the seat-adjustment assembly to bias the seat-mounting plate. A second phase involves the second linear actuator rotating the motor tube angularly within a second range of degrees, causing the footrest assembly to extend or retract without affecting the back-mounting link bias. A third phase involves a first linear actuator causing the lift assembly to raise and tilt the base plate directly over the lift-base assembly.
