A transformable seat assembly , comprising: a seat support structure ; a back support structure is connected to the seat support structure with a hinge wherein the hinge defines an axis of rotation ; an actuator assembly comprising a cylinder and a piston positioned within the cylinder , wherein: the cylinder is secured to one of the back support structure or the seat support structure ; the piston is secured to other of the one of the back support structure or the seat support structure ; and a blocking member positioned within and adjustable along the cylinder wherein: with the blocking member in a first position , the blocking member limits linear travel of the piston in a first direction to a first limit position of the piston such that rotational travel of the back support structure about the axis of rotation is limited from rotating the back support structure beyond a first reclined position (FR); and with the blocking member in a second position , the blocking member permits linear travel of the piston in the first direction beyond the first limit position of the piston such that rotational travel of the back support structure about the axis of rotation is permitted to rotate beyond the first reclined position (FR) to a second reclined position (SR). a seat support structure ; a back support structure is connected to the seat support structure with a hinge wherein the hinge defines an axis of rotation ; an actuator assembly comprising a cylinder and a piston positioned within the cylinder , wherein: the cylinder is secured to one of the back support structure or the seat support structure ; the piston is secured to other of the one of the back support structure or the seat support structure ; and the cylinder is secured to one of the back support structure or the seat support structure ; the piston is secured to other of the one of the back support structure or the seat support structure ; and a blocking member positioned within and adjustable along the cylinder wherein: with the blocking member in a first position , the blocking member limits linear travel of the piston in a first direction to a first limit position of the piston such that rotational travel of the back support structure about the axis of rotation is limited from rotating the back support structure beyond a first reclined position (FR); and with the blocking member in a second position , the blocking member permits linear travel of the piston in the first direction beyond the first limit position of the piston such that rotational travel of the back support structure about the axis of rotation is permitted to rotate beyond the first reclined position (FR) to a second reclined position (SR). with the blocking member in a first position , the blocking member limits linear travel of the piston in a first direction to a first limit position of the piston such that rotational travel of the back support structure about the axis of rotation is limited from rotating the back support structure beyond a first reclined position (FR); and with the blocking member in a second position , the blocking member permits linear travel of the piston in the first direction beyond the first limit position of the piston such that rotational travel of the back support structure about the axis of rotation is permitted to rotate beyond the first reclined position (FR) to a second reclined position (SR). <EOS>
