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 and a back-mounting link coupled to a seat-mounting plate, a base plate coupled to a lift-base assembly via a lift assembly, a seat-adjustment assembly including a drive bracket, and a linear actuator for automating adjustment of the linkage mechanism. In operation, a stroke in a first phase of the linear actuator rotates the drive bracket a first angular increment causing the seat-adjustment assembly to bias the seat-mounting plate. A stroke in a second phase rotates the drive bracket a second angular increment causing the footrest assembly to extend or retract without affecting the bias of the back-mounting link. A stroke in a third phase causes the lift assembly to raise and tilt the base plate directly over the lift-base assembly.
