Patent number: 11266245Abstract: A linkage for use in reclining furniture may include a back bracket supported by forward and rear back pivot links. The bottom of the rear back pivot link may be pivotably coupled to a rear lift link and the bottom of the forward back pivot link may be pivotably coupled to the rear lift link in a different location. A control link may be pivotably coupled on one end to one of the forward back pivot link and the rear back pivot link. The control link may pull the pivoting linkage of the back bracket and the forward and back pivot links as the overall linkage is moved from a closed to a TV to a full-recline position. The resulting pivot point for the back is projected upwardly and forwardly, to a point where an upholstered back and seat meet on a finished chair.Type: GrantFiled: May 18, 2020Date of Patent: March 8, 2022Assignee: LEGGETT & PLATT, INC.Inventors: Gregory Mark Lawson, Walter Clark Rogers, Jr., Cheston Brett Crawford

Patent number: 11229290Abstract: A seating unit is provided with a glider linkage and a powered reclining mechanism, supported on a pedestal base. The glider linkage allows the seating unit to move to and fro in a gliding motion when the seating unit is in the closed position. The powered reclining mechanism allows independent operation of the footrest and back recline, utilizing a two-motor design. As the seating unit moves from the closed position to the TV position, with the footrest extended, a locking linkage prevents the glider linkage from moving. Additionally, the locking of the glider linkage provides at least a portion of the change in pitch of the seat. The recliner linkage provides the remaining portion of the change in pitch of the seat as the mechanism moves from the closed to the TV position. Because the back recline is independent from the footrest extension, the back can be at least partially reclined even when the seating unit is in the closed position.Type: GrantFiled: July 20, 2020Date of Patent: January 25, 2022Assignee: LEGGETT & PLATT, INC.Inventor: Jason Allan Bryant
