Linkage mechanism for a high-leg seating unit

A seating unit having a seat and at least one ottoman, the seating unit being adapted to move between a closed, an extended, and a reclined position, the seating unit comprising:

• a pair of base plates in substantially parallel-spaced relation, wherein the base plates are mounted to one or more legs that are adapted to vertically raise and support the base plates above an underlying surface;
• a pair of seat-mounting plates in substantially parallel-spaced relation, wherein the seat-mounting plates translatably carry the seat over the base plates;
• and
• a pair of the generally mirror-image linkage mechanisms each moveably interconnecting each of the base plates to a respective seat-mounting plate, and wherein each of the linkage mechanisms include a footrest assembly for extending the at least one ottoman as well as a seat-adjustment assembly comprising:
• (a) an ottoman drive link having a front end and a rear end, wherein the front end of the ottoman drive link is pivotably coupled to the footrest assembly;
• (b) a connecting link having a front end, a mid section, and a rear end, wherein the mid section of the connecting link is pivotably coupled to the rear end of the ottoman drive link, while the front end of the connecting link is rotatably coupled to a forward portion of a respective base plate;
• (c) a rear pivot link having an upper end, a mid section, and a lower end, wherein the upper end of the rear pivot link is pivotably coupled to a rearward portion of a respective seat-mounting plate, while the lower end of the rear pivot link is rotatably coupled to the rear end of the connecting link;
• (d) a front bellcrank having an upper end, a mid section, and a lower end, wherein the upper end of the front bellcrank is rotatably coupled to a forward portion of a respective seat-mounting plate;
• and
• (e) a support link having a front end, a mid section, and a rear end, wherein the rear end of the support link is pivotably coupled to a rearward portion of a respective base plate, while the front end of the support link is pivotably coupled to the mid section of the front bellcrank.

A linkage mechanism adapted to adjust a recliner seating unit between closed, extended, and reclined positions, the linkage mechanism comprising:

• a seat-mounting plate configured to accommodate a seat of the recliner seating unit;
• a base plate that includes a forward portion and a rearward portion, wherein a sequence element extends outward from the forward portion of the base plate;
• a footrest assembly adapted to extend and retract at least one ottoman when the recliner seating unit is adjusted between the extended and closed positions, respectively;
• and
• a seat-adjustment assembly comprising:
• (a) a front bellcrank that is rotatably coupled to a forward portion of the seat-mounting plate;
• (b) a support link that includes a front end and a rear end, wherein the rear end of the support link is pivotably coupled to a rearward portion of the base plate, while the front end of the support link is pivotably coupled to the front bellcrank;
• (c) a sequence link that includes a first end and a second end, wherein the first end is pivotably coupled to the front bellcrank, while the second end includes a guide slot formed therein for rotatably and slidably engaging with the sequence element;
• (d) an ottoman drive link having a front end and a rear end, wherein the front end of the ottoman drive link is pivotably coupled to the footrest assembly;
• and
• (e) a connecting link having a front end, a mid section, and a rear end, wherein the mid section of the connecting link is pivotably coupled to the rear end of the ottoman drive link, while the front end of the connecting link is rotatably coupled to a forward portion of the base plate.
