Driver restraints and dummy kinematics Dummy movement was reasonably well controlled. There was far too much upward movement of the steering wheel, which contributed to the dummy's head bottoming out the airbag and hitting 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, together with the footwell intrusion, indicate that the driver space wasn't maintained well.
Upward movement of the steering wheel contributed to the dummy's head bottoming out the airbag and hitting the wheel.
Intrusion into the footwell area caused separation of the floor, which trapped the dummy's left foot under the brake pedal and contributed to high crash forces near the ankle.
