Wheel deflector for a small overlap crash
A system for managing wheel kinematics during a small overlap collision event includes a deflector apparatus. The deflector is configured to direct a wheel away from an occupant compartment of a vehicle. The deflector includes a first section arranged at an inside wall of a wheel well facing a wheel, near the base of a hinge-pillar. The first section includes a hollow structure configured to absorb energy from the collision event by plastically deforming. The deflector also includes a second section arranged at an angle to the wheel and configured to deflect the wheel laterally outwards from the vehicle away from an occupant compartment during the small overlap collision event. The deflector may be formed of extruded aluminum. The system may include an absorber arranged behind the first section and configured to further absorb energy from the collision event by plastically deforming.
