Restraints and dummy kinematics

Action shot taken during the small overlap frontal crash test.

The dummy's position in relation to the door frame, steering wheel, and instrument panel after the crash test indicates that the driver's survival space was maintained very well.

The dummy's head contacted the frontal airbag but slid partway off the left side, allowing the head to move toward the gap in coverage between the frontal and side curtain airbags.

The driver's space was maintained well, and risk of injuries to the dummy's legs and feet was low.
