WebJul 18, 2024 · Think of the crumple zone as a buffer around your vehicle that helps absorb and cushion the blow of a collision by extending your deceleration time, so your car stops (relatively) slowly, rather than suddenly, to minimize the force that you and your passengers are subjected to. While the crumpling may cause more damage to your vehicle, the ... WebSep 25, 2024 · Crumple zones, crush zones or crash zones, are structural safety features used in vehicles, mainly in automobiles. These zones increase the time of the impact during a collision by controlling deformation. Thus, they reduce the effect of the impact or absorb the inertia forces as a result of the impact of a crash. Car Body Shell.

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. Since the change in K remains the same, an increase in distance decreases the force acted on the occupant of the vehicle.
