A seating unit, comprising: a pair of base plates in substantially parallel-spaced relation; a pair of seat-mounting plates in substantially parallel-spaced relation, wherein each of the seat-mounting plates is disposed in an inclined orientation in relation to each of the base plates, respectively; and a pair of generally mirror-image linkage mechanisms each moveably interconnecting each of the base plates to a respective seat-mounting plate, and adapted to adjust between a closed position, an extended position, and a reclined position, wherein each of the linkage mechanisms comprise: (a) a back-mounting link that supports a backrest, wherein the back-mounting link is rotatably coupled to a respective seat-mounting plate; (b) a member that extends downward from a rear portion of a respective seat-mounting plate; (c) a rear pivot link that includes an upper end and a lower end, wherein the lower end of the rear pivot link is rotatably coupled to a respective base plate; (d) a back control link that includes an upper end and a lower end, wherein the upper end of the back control link is pivotably coupled to the back-mounting link; (e) a rear bellcrank that is rotatably coupled to the member and pivotably coupled to the lower end of the back control link and to the upper end of the rear pivot link; (f) a front lift assembly that moveably interconnects a forward portion of a respective base plate and a forward portion of a respective seat-mounting plate, wherein the front lift assembly includes a front lift link that is rotatably coupled to a respective seat-mounting plate; (g) a rear control link that includes a front end and a rear end, wherein the front end of the rear control link is pivotably coupled to the front lift link and the rear end of the rear control link is pivotably coupled to the rear bellcrank, wherein the interaction of the front lift assembly and the rear bellcrank via the rear control link maintains a substantially consistent angle of inclination between a respective seat-mounting plate and a respective base plate when adjusting the linkage mechanisms between the closed position, the extended position, and the reclined position. (a) a back-mounting link that supports a backrest, wherein the back-mounting link is rotatably coupled to a respective seat-mounting plate; (b) a member that extends downward from a rear portion of a respective seat-mounting plate; (c) a rear pivot link that includes an upper end and a lower end, wherein the lower end of the rear pivot link is rotatably coupled to a respective base plate; (d) a back control link that includes an upper end and a lower end, wherein the upper end of the back control link is pivotably coupled to the back-mounting link; (e) a rear bellcrank that is rotatably coupled to the member and pivotably coupled to the lower end of the back control link and to the upper end of the rear pivot link; (f) a front lift assembly that moveably interconnects a forward portion of a respective base plate and a forward portion of a respective seat-mounting plate, wherein the front lift assembly includes a front lift link that is rotatably coupled to a respective seat-mounting plate; (g) a rear control link that includes a front end and a rear end, wherein the front end of the rear control link is pivotably coupled to the front lift link and the rear end of the rear control link is pivotably coupled to the rear bellcrank, wherein the interaction of the front lift assembly and the rear bellcrank via the rear control link maintains a substantially consistent angle of inclination between a respective seat-mounting plate and a respective base plate when adjusting the linkage mechanisms between the closed position, the extended position, and the reclined position.
