A reduced shear reclining seat back assembly employs a single rotary actuator for reclining a seat back relative to a seat portion and controlling movement of a seat back member in response to the reclining operation. A rotary actuator includes a first arm pivotally secured to the seat back, preferably through a link which is connected to the movable back member. A second arm of the actuator is pivotally secured to the seat portion. As the angle between the first and second arms decreases, the seat back reclines and the movable seat back member is drawn toward a seat pivot axis. Likewise, when the angle between the arms increases, the seat back is brought to an upright position and the movable seat member travels away from the seat pivot axis. |
