| Driver restraints and dummy kinematics The dummy’s head barely contacted the frontal airbag before sliding off the left side as the steering column moved 12 cm to the right. Additionally, the seat belt allowed excessive forward excursion of the dummy’s head and torso, contributing to the head hitting the instrument panel. The side curtain airbag deployed but does not have sufficient forward coverage to protect the head from contact with forward side structure and outside objects, and the driver's seat tipped forward and toward the B-pillar. The side torso airbag deployed. |
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 not maintained well.
During the crash, the dummy's head and torso barely contacted the airbag before sliding off to the left as the steering column moved to the right, and the driver's seat pitched forward and tipped outward.
Door hinge pillar and instrument panel intrusion was extensive and contributed to a high risk of injury to the left lower leg.
