Patent number: 11622629Abstract: A furniture member includes a base assembly, a frame assembly, a legrest mechanism, a support rod, and a sync mechanism. The frame assembly is movable relative to the base assembly among an upright position, a partially reclined position, and a fully reclined position. The legrest mechanism is movable relative to the frame assembly between a retracted position and a fully extended position. The support rod is supported by the frame assembly. The sync mechanism is coupled to and supported by the support rod. The sync mechanism is configured to prevent the frame assembly from moving from the upright position to the partially reclined position until the legrest mechanism reaches the fully extended position.Type: GrantFiled: December 13, 2021Date of Patent: April 11, 2023Assignee: La-Z-Boy IncorporatedInventors: Larry P. LaPointe, Jaime A. McPherson, Christopher A. Larsen, Randy Loper, Richard D. Hartford, Chandrasekar Ramasubramanian

Patent number: 10568428Abstract: A furniture member may include a stationary frame assembly and a seatback cushion. The stationary frame assembly may include a stationary base frame, a pair of stationary armrest frames and a stationary seatback frame that is fixed relative to the stationary base frame and the stationary armrest frames. The seatback cushion may include upholstery attached to at least one of the armrest frames. The upholstery may include a portion disposed between the at least one of the armrest frames and the seatback cushion. The portion of the upholstery may be expandable to allow movement of the seatback cushion relative to the stationary base frame, the stationary armrest frames and the stationary seatback frame between an upright position and a reclined position.Type: GrantFiled: December 5, 2017Date of Patent: February 25, 2020Assignee: LA-Z-BOY INCORPORATEDInventors: Richard E.

Patent number: 10537178Abstract: A furniture member may include a stationary seatback frame, a seat bottom assembly, a legrest mechanism, and a backrest support spring. The seat bottom assembly is movable relative to the seatback frame between a nominal position and a tilt position. The legrest mechanism is movable among a retracted position, a first extended position and a second extended position. A portion of the legrest mechanism contacts the seat bottom assembly when the legrest mechanism is in the first extended position and pushes the seat bottom assembly from the nominal position to the tilt position as the legrest mechanism moves from the first extended position to the second extended position. The backrest support spring includes a first end attached to the seatback frame and a second end attached to the seat bottom assembly and movable with the seat bottom assembly relative to the seatback frame.Type: GrantFiled: April 7, 2017Date of Patent: January 21, 2020Assignee: La-Z-Boy IncorporatedInventors: Richard E. Marshall, Eugene O. Cole, II, Chandrasekar Ramasubramanian, Stephen Andrew Brown, Jason Rains, Jason Bryson

Patent number: 9986835Abstract: A furniture member may include a base frame and a seat assembly mounted on the base frame. The seat assembly may include a seat frame, a seatback, a seat bottom, a rocker member, a legrest mechanism, and a tilt mechanism. The rocker member is attached to the seat frame and rollingly contacts the base frame. The rocker member supports the seat assembly relative to the base frame such that the seat assembly is movable between a rocked-back tilt position and a rocked-forward tilt position. The legrest mechanism is mounted to the seat frame and attached to a legrest platform. The legrest mechanism may include a drive rod coupled to a pantograph linkage that is movable relative to the seat frame between retracted and extended positions. The tilt mechanism selectively locks the seat assembly in one of an infinite number of tilt positions between the rocked-back and rocked-forward tilt positions.Type: GrantFiled: September 22, 2016Date of Patent: June 5, 2018Assignee: La-Z-Boy IncorporatedInventors: Larry P. Lapointe, Chad E. Adams, Chandrasekar Ramasubramanian
