Independent Study Project: The Chemistry Behind The Airbag

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.

The headrest was invented by Benjamin Katz in 1921. He created the headrest to prevent movement of a person's head during collisions. It was found that the headrest eliminated whiplash or several injuries to the cervical vertebrae during a car crash. Katz also created the headrest as an emergency device to break a window and get out of the car in case of an accident where you cannot get out of the doors. This invention soon reached worldwide popularity due to the comfort and safety they provided to automobile users. After January 1st, 1969, the National Highway Traffic Safety Administration (NHTSA) mandated the use of headrests in all new cars sold. Since Katz's invention, the headrest has gone through many changes, including safety, comfort,

Have you ever wondered why we need airbags? Cars have been around for multiple years now and have had many flaws. Many tests have been done to prevent these flaws. People are debating on if airbags are one of those flaws. People may believe that they don’t stop people from getting hurt. This is incorrect because of Newton's first law.

Manufacturing issue with the police vehicle extra equipment’s holes are not properly seal up with foam and sealant which consequently allow the carbon monoxide from the exhaust to enter through the unsealed seams in the rear of the SUV [1] (Follow the money & fact)

Front air bags have been on all new cars since 1998 and light trucks since 1999. Most vehicles had them before. Crash sensors connect to a computer and can detect a front collision and trigger the bags. The bags inflate in a few milliseconds then it starts deflating.

A passive restraint device is very important for any driver whether they are advanced or a beginner. They can save you in the time of a car crash, giving you and others in the car a chance to survive. Although, you can still be injured from the collision since the air bag will burst from the wheel to cushion the impact. You can prevent from using it by following basic driving laws, and staying aware of your

The airbags purpose is to move out quickly enough for a head-on collision, to prevent any harm to the individuals in the vehicle during a car accident. The airbag system consists of a crash sensor(accelerometer),that detects when a car decelerates very quickly, which then causes the ball(crash sensor) to move forward and turn on the electrical circuit which causes the process of inflation to occur. The gas generator in the airbag contains a mixture of NaN3, KNO3, and SiO2.The current pulse heats up the sodium Azide, which then decomposes it into sodium and nitrogen gas. Silicon dioxide, sodium oxide, and potassium oxide formed then turn into glass. That fire triggered the chemical reaction that filled the nylon fabric airbag

So, the latest Toyota Corolla iM is no different. It comes with curtain airbags, driver’s knee airbag, side airbags and seat cushion airbag to keep the front passenger safe during a collision.

The airbags have a sensor that contains a steel ball attached to a permanent magnet or a stiff spring. The spring or magnet holds the ball in place through minor accidents when an airbag is not needed—for example, if a car is slightly bumped by another car in a parking lot. When a car goes through a severe collision, a series of three chemical reactions inside the gas generator produces nitrogen gas (N2) that fills the airbag and decomposes the sodium azide (NaN3). The role of the potassium nitrate (KNO3) and silicon

Air bags are made out of a fabric, like nylon. They saved around 15,000, inside the car pedestrians, over the last 20 years. They are in about every car in the world. They save a lot of people involved in crashes inside the car, but don’t help the people outside of the car. Many people get in a car accident and there are surrounding pedestrian who are in harm’s way. They may be injured or killed during these vehicular accidents. There is nothing protecting these people walking on the sidewalks, in the cross walk, biking, or are just near the roads. That is why many companies are looking to add new airbags, not only on the inside off cars, but on the outside.

An airbag is a vehicle safety device. The airbag like seatbelts are occupant restraint system that consists of a flexible fabric bag, also known as an airbag cushion. The airbag module is designed to inflate rapidly then quickly deflate during a collision or impact with another object or a sudden deceleration. The purpose of the airbag is to provide occupant protection and restraint during a crash event.

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.

Airbags are safety features that are designed to save passengers from harm in a head-on collision. Airbags react within milliseconds of a crash, and the folded nylon bag quickly becomes inflated with nitrogen gas. The inflated airbag has the role of being a cushion for passengers and prevents them from hitting into the steering column and dashboard, which can cause painful injuries for passengers.

Airbags want to slow the speed of the passengers’ forward motion with little or no damage within a fraction of a second. The law that applies here is inertia, Newton’s first law. It states that an object wants to keep on doing what it’s doing and will do so unless an outside force is acted upon it.
