摘要:
A seating unit that includes a linkage mechanism adapted to adjust between closed, extended, and reclined positions is provided. The linkage mechanism includes a seat-mounting plate mounted to a footrest assembly, a back-mounting link and a rear bellcrank both rotatably coupled to the seat-mounting plate, an activator bar that controls a footrest drive link, and a linear actuator for carrying out automated adjustment of the linkage assembly. In operation, a stroke in a first phase of the linear actuator generates a torque on the activator bar. The footrest drive link converts the torque into a laterally-directed force that pushes the footrest assembly into the extended position. A stroke in the second phase acts to push the activator bar forward and translate the seat-mounting plate forward at a consistent inclination angle. The forward translation causes the rear bellcrank to rotate, thereby biasing the back-mounting link rearward into the reclined position.
