Abstract: A seating arrangement includes a seat arrangement that includes first, second, third and fourth link members coupled to one another, a back arrangement movable between an upright position and a reclined position and coupled to the seat arrangement such that the first link member moves between forward and rearward positions as the back arrangement is moved between the upright and reclined positions, and a stop arrangement including a stop link coupled to at least one of the first link member, the third link and the fourth link member such that the stop link moves with the associated link member as the back assembly moves between the upright and reclined positions, wherein travel of the stop link is limited with respect to the second link member thereby limiting a rearward movement of the back arrangement toward the reclined position.
