What is the science behind the seat belt? [Answered!]

WebAir bags do not just reduce the impact force by elongating the time factor, they also spread the impact over a larger contact area. By doing this, the force is not all concentrated in one small area of your body and the pressure on your body is reduced. This in turn will cause the seriousness your injuries to be reduced. WebApr 9, 2002 · A seatbelt's job is to spread the stopping force across sturdier parts of your body in order to minimize damage. A typical seatbelt consists of a lap belt, which rests over your pelvis, and a shoulder belt, which extends across your chest. The two belt sections are tightly secured to the frame of the car in order to hold passengers in their seats. port greenwich limited
