a pair of oppositely disposed sidewall mounting brackets;
a front support tube and a rear support tube;
a first set of bolt fasteners fixedly securing a first pair of said plurality of support legs to said front support tube while simultaneously fixedly securing said front support tube to front portions of said pair of oppositely disposed sidewall mounting brackets; and
a second set of bolt fasteners fixedly securing a second pair of said plurality of support legs to said rear support tube while simultaneously fixedly securing said rear support tube to rear portions of said pair of oppositely disposed sidewall mounting brackets.
11. A powered furniture seating piece, comprising:
a base or foundation;
a seat rail, for supporting a seat section of said furniture piece, operatively connected to said base or foundation;
a back support bracket, fixedly connected to said seat rail, for supporting a back section of said furniture piece;
a footrest mounting bracket for supporting a footrest section of said furniture piece;
an ottoman drive link pivotally mounted upon said seat rail and operatively connected to said footrest mounting bracket;
a linear actuator connected to said ottoman drive link; and
a control link pivotally mounted upon said seat rail such that when said linear actuator is extended to a first predetermined position, said control link will permit said ottoman drive link to move said footrest mounting bracket from a retracted closed position to an extended open position, but will prevent said back support bracket from being moved from an upright position to a reclined position whereby said actuating mechanism will be disposed at a TV position, and when said linear actuator is extended to a second predetermined position, said control link will permit said back support bracket to move from said upright position to a reclined position whereby said actuating mechanism will be disposed at a fully RECLINED position.
12. The powered furniture seating piece as set forth in claim 11 , wherein:
a pivot link is operatively connected to said back support bracket;
said control link comprises a control link slot; and
a control link slot follower pin fixedly mounted upon said pivot link and operatively disposed within said control link slot of said control link for controlling said movements of said back support bracket between said upright position and said reclined position.
