Why are crumple zones useful

Crumple zones are areas of a vehicle that are designed to crush in a controlled way in a collision. They increase the time taken to change the momentum of the driver and passengers in a crash, which reduces the force involved. Car safety features When there is a car crash, the car, its contents and the passengers decelerate rapidly. These typically include: seat belts air bags crumple zones These features reduce injuries to the people in the car by absorbing energy from the impact.

Seat belts Seat belts stop you tumbling around inside the car if there is a collision. Safety specialists must find the right balance between too much and too little resistance. Many simple crumple zone designs involve frames that bend or collapse into themselves upon impact. Advanced designs may use different metals and other materials that, when used together, absorb more kinetic energy. While crumple zones can help lessen injuries and save lives, there are other safety features to consider when purchasing a new car.

Crumple zones add time to the crash by absorbing energy. The front of the vehicle effectively acts as a cushion that slows the time it takes for the vehicle to come to a complete stop, applying less force on passengers, which could help save their lives.

But in actuality, such construction proved deadly to passengers, because the force from impact went straight inside the vehicle and onto the passenger. These features reduce injuries to the people in the car by absorbing energy from the impact.

These features absorb energy when they change shape. This reduces injuries to the people in the car. They increase the time taken for the change in momentum on the occupants' bodies, and so reduce the forces involved and any subsequent injuries.
