Zero-wall clearance linkage mechanism for providing additional layout

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.

主权项

1. A reclining mechanism for a seating unit, the reclining mechanism comprising:
a base plate; a seat-mounting plate that is spaced apart from the base plate and that includes a stop extending from a rearward portion of the seat-mounting plate; and a linkage mechanism that moveably interconnects the base plate to the seat-mounting plate and that is adapted to move between a closed position, an extended position, and a reclined position, wherein the linkage mechanism comprises a back-mounting link that is usable to support a backrest and that is pivotably coupled to a rearward portion of the seat-mounting plate, the back-mounting link comprising a portion that engages the stop; and wherein the portion of the back-mounting link engages the stop to limit an amount of incline achievable in the closed position and an amount of recline achievable in the reclined position.
