The safety features of a car are crucial in preventing accidents and minimizing the impact of crashes. One of the most critical safety features is the airbag system, which is designed to deploy in the event of a collision to protect the occupants of the vehicle. Airbags are designed to absorb the impact of a crash, reducing the risk of injury or fatality. But have you ever wondered what gas is used in airbags of cars? In this article, we will delve into the world of airbags and explore the type of gas used in these life-saving devices.

The History of Airbags
Airbags have been around since the 1950s, but they were not widely used until the 1980s. The first airbag was invented by an American inventor named John W. Hetrick, who patented a “safety cushion” in 1951. However, it wasn’t until the 1980s that airbags became a standard feature in many cars. The first production airbag was introduced in 1984 by the Ford Motor Company, and it was designed to deploy in the event of a frontal collision.
The Science Behind Airbags
Airbags are designed to deploy in a matter of milliseconds in the event of a collision. This is made possible by a complex system of sensors, wiring, and electronic control units. The airbag system is designed to detect the severity of a crash and deploy the airbag accordingly. The airbag itself is made up of a flexible material that inflates with gas when the system deploys.
The Gas Used in Airbags
The gas used in airbags is a critical component of the system. The gas must be able to inflate the airbag quickly and safely, while also providing sufficient cushioning to protect the occupants of the vehicle. The most common gas used in airbags is nitrogen (N2), which is a colorless, odorless, and tasteless gas. Nitrogen is used because it is non-toxic and non-flammable, making it a safe choice for use in airbags.
| Properties of Nitrogen | Description |
|---|---|
| Nitrogen (N2) | A colorless, odorless, and tasteless gas |
| Non-toxic | Safe for use in airbags |
| Non-flammable | Prevents fires in the event of a crash |
How Airbags Work
Airbags work by deploying in a matter of milliseconds in the event of a collision. The deployment process is triggered by a complex system of sensors and electronic control units. Here’s a step-by-step explanation of how airbags work: (See Also: Car Leaks Gas When Filling? Stop The Spill)
- Sensors detect the severity of a crash and send a signal to the electronic control unit.
- The electronic control unit determines whether the crash is severe enough to deploy the airbag.
- If the crash is severe enough, the electronic control unit sends an electrical signal to the airbag inflator.
- The airbag inflator uses a propellant to inflate the airbag with nitrogen gas.
- The airbag inflates in a matter of milliseconds, providing a cushion of air to protect the occupants of the vehicle.
Types of Airbags
There are several types of airbags used in cars, including:
- Frontal airbags: These airbags deploy in the event of a frontal collision to protect the driver and passenger.
- Side airbags: These airbags deploy in the event of a side collision to protect the occupants of the vehicle.
- Rear airbags: These airbags deploy in the event of a rear-end collision to protect the occupants of the vehicle.
- Knee airbags: These airbags deploy in the event of a frontal collision to protect the driver’s knees.
- Curtain airbags: These airbags deploy in the event of a side collision to protect the occupants of the vehicle.
Conclusion
Airbags are a critical safety feature in cars, designed to protect the occupants of the vehicle in the event of a collision. The gas used in airbags is a critical component of the system, and nitrogen is the most common gas used due to its non-toxic and non-flammable properties. Understanding how airbags work and the types of airbags used in cars can help drivers appreciate the importance of this safety feature.
