WebSep 28, 2024 · In a typical seatbelt system, the belt webbing is connected to a retractor mechanism. The central element in the retractor is a spool, which is attached to one end of the webbing. Inside the retractor, a spring applies a rotation force, or torque, to the spool. How do seat belts keep people safe during collisions? WebIn terms of physics, a seat belt increases the stopping distance of an occupant during a car crash. According to the work-energy principle, this lessens the impact force applied to the occupant. Work = Δ Kinetic Energy. (Force) (distance) = Δ½ (mass) (velocity) 2. Since the change in K remains the same, an increase in distance decreases the ...
