A seating unit that includes a linkage mechanism adapted to move the seating unit between extended and reclined positions, and a chassis is provided. The linkage mechanism includes a seat-mounting link, a base plate fixedly mounted to the chassis, a back- mounting bracket rotatably coupled to the seat-mounting link, a back drive link in generally laterally-spaced relation to the seat-mounting link, and a front-lift assembly that is rotatably coupled to the seat-mounting link. In operation, a rearward occupant force on the back- mounting bracket generates a rearward bias that is converted to a laterally-directed force through the back drive link to the front-lift assembly. Upon receiving this force, the front- lift assembly translates the seat- mounting link forward and upward in relation to the base plate, such that, the seat-mounting link is consistently biased in a particular inclination angle with respect to the base plate throughout adjustment. |
