Crumple Zones Inertia

There are many people who do not understand the importance of seat belts for safety. They do not wear their seat belts even though they know the mortality statistics. Most of them think that seat belts do not help when an accident occurs. We have all made the excuse that the seat belt is uncomfortable. Driving is a dangerous duty that should always be practiced with more caution and care. Some people think that not wearing a seatbelt is rebellious. Other people think that they will never get into accident. Some of the consequences of not wearing a seat belt is that you could die, you can get injured and many more. So far, the only way to avoid these consequences from happening is to wear a seatbelt.

Crumple zones are structural areas in the front, sometimes rear of a vehicle that are designed to absorb energy upon impact in a predictable way.

In the past years, car accidents are the leading cause of death. In 2009 alone, crashes killed over 33,000 people and injured another 2.2 million. More than half of the people killed in car crashes were not restrained at the time of the crash. I know most of you guys probably don’t want to hear me talk about statistics or about seatbelts and why you should wear them and listen to some boring speech you have heard time and time again. But please hear me out. You might have excuses that sound logical in your mind, but what are you going to do when your excuses get you killed? First of all, I know most people think that seat belt laws are ridiculous and keep you from having fun.

1.Wearing seat belt saves many people.Seat belt use virtually eliminates the possibility of ejection from the vehicle.Wearing seat belt keeps you from being thrown from your vehicle..It keeps you from banging against parts of your car such as the door.It can also keep you not to hit to steering and the thing in front of you.Seat belts keep the driver and passengers from banging each other, a cause of real injury in some accidents.Airbags are some times useless if you are not wearing seat belt,you can be thrown from your car.If you has thrown from the car, you can be hit some parts of car.So people wearing seat belts can be illegal.

Racing seats have shoulder straps that hold the driver snugly to the seat. A crash at these speeds can rip a

Crumple zones are designed to absorb the energy from the impact during a traffic collision by controlled deformation. This energy is much greater than is commonly realized. A 2,000 kg (4,409 lb) car travelling at 60 km/h (37 mph) (16.7 m/s), before crashing into a thick concrete wall, is subject to the same impact force as a front-down drop from a height of 14.2 m (47 ft) crashing on to a solid concrete surface. Increasing that speed by 50% to 90 km/h (56 mph) (25 m/s) compares to a fall from 32 m (105 ft) - an increase of 125%. This is because the stored kinetic energy (E) is given by E = (1/2) mass × speed squared. It increases by the square of the impact velocity.

According to NHTSA, 13,941 lives were saved by seat belts in 2015 while an additional 2,814 could have been saved if properly restrained (2017). One impact of seat belt usage is reducing the risk serious or fatal injuries by about half. The CDC reported in 2009, 53% of occupants killed in crashes in the U.S. were not wearing seat belts (2014). According to data collected in 2008 by NHTSA, seat belts have saved an estimated 225,000 lives (2009). The benefit of wearing a seat belt can help increase chances of surviving a crash with little or no

Inertia is the quality of being unchanged. If a person is not wearing a seatbelt during a collision they will not stop, the seatbelt does it so that after the collision and the car stops, the person involved could stop too.

According to the National Highway Traffic Safety Administration (NHTSA), “in 2015, seat belt use in passenger vehicles saved an estimated 13,941 lives” (1). The NHTSA goes on to say that almost 30 million Americans still don’t use seat belts on a daily basis. Since vehicle accidents are among the leading causes of death in the United States and even the world, the argument to improve seat belt technology has increased dramatically. Researchers are often more concerned with whether or not people are wearing their seat belts, not the effectiveness of them, until now, although both are incredibly important. Seat belt safety, which is directly related to seat belt technology, has been shown to be increasingly ineffective because of the high severity

When the car is moving at 70 mph, the passenger/driver is moving at 70 mph. if the car suddenly hits a wall. the car stops moving, but the passenger is still moving at 70 mph... the seat belt prevents the passenger from flying out of the windshield / cutting their head open on the windshield. (this is based on inertia)

For the people who use the excuse that "They are just going around the corner" should realize that 80% of traffic fatalities occur within a 25-mile radius of your home and at a speed of 40 miles an hour. Buckling up to drive around the block is probably the best time to do so. Everyone knows that car crashes can cause death; yet because people do not buckle up all the time thousands of people still die in traffic crashes yearly. Seatbelts can save your life in a crash and can reduce your risk of a serious injury. Seat belts keep drivers and passengers from being ejected through windows or doors. This is important because your chances of being killed are five times greater if you are thrown from the vehicle. Thousands of people who die in car crashes each year might still be alive today if they had only been wearing their seat belts.

Seat Belts keep drivers and passengers in the car from being tossed around like rag dolls. “Buckling up is the single most effective thing you can do to protect yourself and your passengers in a crash,” the California Highway Patrol explains. Its impetrative that you always wear them before you start driving. If you have any children, it important to have them in car seats so that seat belts can help protect children in crashes. “The rate of motor vehicle crash deaths per million children younger than 13 is less than a quarter of what it was in 1975,” the Insurance Institute for Highway Safety reports, “The rate at which children die as passenger vehicle occupants has decreased 60 percent, while the rates at which they are killed as pedestrians and bicyclists are each about one-tenth of 1975 rates.” The number of deaths among young children has declined since 1975 and parents contributed to decline by buckling up their kids in the backseat. The decline is also the result of many states laws that have took

Seat belts worn correctly can reduce the chances of death in a collision by 47% and the chances of serious injury by 52% (Stewart et al., 1997). All new vehicles sold in Canada today are equipped with three-point seat belts in all positions. Many vehicles are also equipped with seat belt pretensioners,

Every day, thousands of individuals fall victim to motor vehicle accidents and obtain serious injuries. But in regards to innovations such as seat belts and airbags, this number has decreased. Safety innovations have changed throughout history. In the 1930’s, individuals were required to wear safety glasses in their vehicles, in the late 1950’s, occupants were allowed to choose whether they wanted headrests on the front seats, which we know understand to be a crucial part of a car as it prevents whiplash. More recently there have been new innovations such as tire pressure monitors and traction control which further contributes to reducing the number of roadside accidents. However, it is clear that there is still a large area for improvement.

Seat belts although they are the most effective safety device on cars must be made safer. Out of all people who died in car accidents, 63% of those were not wearing seat belts (seatbelts). This goes to show you the effectiveness of seat belt. Therefore automotive manufactures must mandate the installation of 5-point seatbelt on all cars. In all major race car organization such as NASCAR (National Association Stock Car Automotive Racing) they require these 5-point seat belt. Which is nothing more than a seatbelt that is buckled in 5 spots rather that the conventional 3.
