| 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. |
Action shot taken during the frontal offset crash test.
The dummy's position in relation to the steering wheel and instrument panel after the crash test -- plus footwell intrusion and door sill crushing -- indicate the driver's survival space wasn't maintained well.
Smeared greasepaint indicates where the dummy's head hit the B-pillar during rebound, producing a high head acceleration.
Footwell intrusion contributed to the possibility of injury to the lower right leg.
