摘要： A seatback member cam adjustment system includes a seat link having a first bore and a seatback link rotatably connected to the seat link. The seatback link includes an arm portion and a leg portion connected to the arm portion. The leg portion is angularly oriented to the arm portion, and includes a second bore smaller than the first bore. A cam member cam body is positioned in the first bore. A cam body obround cam surface has oppositely facing first and second cam contact points both in direct contact with a first bore inner wall. A cam mount shaft is rotatably supported in the cam member including and extends through the second bore rotatably supporting the cam mount shaft in the second bore. Cam member rotation displaces the cam contact points along the first bore inner wall changing an arm portion orientation angle and a seatback member orientation angle.

摘要： 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.

摘要： An article of furniture may include a seat link and a seatback link. The seat link may include first, second and third apertures. The seatback link may be rotatably coupled to the seat link and may include fourth, fifth and sixth apertures. The seatback link and a seatback frame may be rotatable relative to the seat link and a seat-bottom frame among a first position in which only the first and fourth apertures are coaxially aligned, a second position in which only the second and fifth apertures are coaxially aligned, and a third position in which only the third and sixth apertures are coaxially aligned. The seatback link may be rotationally locked relative to the seat link by inserting a fastener in the first and fourth apertures in the first position, the second and fifth apertures in the second position, and the third and sixth apertures in the third position.
