Why Safety Belts? :: Car collisions

Why Safety Belts?To understand the assess of safety belt use, its important to understand or so of the dynamics of a crash. Every motor vehicle crash is actually comprised of three impacts. The Cars encounterThe first collision is known as the cars collision, which causes the car to buckle and avoid as it hits something and comes to an abrupt stop. This occurs in approximately one-tenth of a second. The devastating of the scarer end absorbs some of the force of the crash and cushions the rest of the car. As a result, the passenger compartment comes to a more gradual stop than the front of the car. The Human impactThe second collision occurs as the cars occupants hit some part of the vehicle. At the moment of impact, unbelted occupants are still travelling at the vehicles original speed. Just after the vehicle comes to a stark(a) stop, these unbelted occupants will slam into the steering wheel, the windshield, or some another(prenominal) part of the vehicle interior. This is the human collision. Another form of human collision is the person-to-person impact. Many serious injuries are caused by unbelted occupants colliding with to each one other. In a crash, occupants tend to move toward the point of impact, not outside(a) from it. People in the front seat are much soft on(p) by unbelted rear-seat passengers who have become high-speed projectiles. The Internal CollisionEven after the occupants body comes to a complete stop, the internal variety meat are still moving forward. Suddenly, these organs hit other organs or the skeletal system. This third collision is the internal collision and often causes serious or fatal injuries. So, Why Safety Belts?During a crash, justly fastened safety belts distribute the forces of rapid deceleration over large and stronger parts of the persons body, such as the chest, hips and shoulders.
