Driver restraints and dummy kinematics
The dummy’s head barely contacted the frontal airbag before sliding off the left side, leaving the head vulnerable to contact with forward structure. Additionally, the seat belt allowed excessive forward excursion of the dummy’s head and torso to the extent the head hit the steering wheel rim. The side curtain airbag deployed and has sufficient forward coverage to protect the head from contact with side structure and outside objects. |
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 well.
During the crash, the dummy's head barely contacted the frontal airbag before sliding off to the left as the steering column moved to the right, and the seat belt allowed far too much forward movement of the dummy.
The driver's space was maintained well, and risk of injuries to the dummy's legs and feet was low.
