| A CRASH
There are 3 collisions in a crash.
Vehicle Collision: This
is the first collision, the vehicle begins to stop as soon as it collides
with a stationary object.
As the vehicle slows, the front of the vehicle crushes,
absorbing some of the energy of the crash.
Human Collision: At the moment of
impact, people in the car are still traveling forward. Occupants
will continue to move toward until they are stopped by something.
For restrained occupants that is the seat belt. For unrestrained
occupants that is usually the steering wheel, dashboard or front
windshield.
Air bags slow the body's movement rather than stopping
it abruptly reducing the likelihood of injury in the second
collision.
Internal Collision: After impact, the brain and internal
organs continue to move forward, or in the direction of travel, tearing
corrective tissue or being bruised by the collision with the skeleton,
including the skull.
Seat belts and air bags also reduce the severity of
these types of injuries.
