US Patent 10537178 Furniture member having flexible seatback

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.
