A reduced shear reclining seat back assembly employs a single rotary actuator (56) to recline a seat back (34) relative to a seat portion (32) and to control movement of a seat back member (74) in response to the reclining operation. The rotary actuator (56) includes a first arm (58) pivotally secured to the seat back (34), preferably through a link (70) which is connected to the movable back member (34). A second arm (80) of the actuator (56) is pivotally secured to the seat portion (32). As the angle between the first and second arms (58, 80) decreases, the seat back (34) reclines and the movable seat back member (74) is drawn toward a seat pivot axis (42). Likewise, when the angle between the arms (58, 80) increases, the seat back (34) is brought to an upright position and the movable seat member (74) travels away from the seat pivot axis (42). <IMAGE> |
