| Driver restraints and dummy kinematics Dummy movement wasn't well controlled. During rebound, the dummy moved toward the driver door, which had bowed outward, and its head hit the window sill. Then the head moved up and back and hit the B-pillar. Plus there was too much upward movement of the steering wheel. |
