Information about Airbags: How They Work and Common Faults

The life and safety of individuals are the top priorities when designing and building any car. Therefore, car companies continuously work on developing and updating a package of safety systems that enhance protection for drivers and passengers on the road. One of the most crucial systems that has become a standard in cars is the Airbag system.

Information about Airbags

Motorcoaster consistently provides you with information about potential car issues and how to handle them. However, we also aim to offer information that guides you to maximum safety on the road. Today, we will share information about airbags, including how they work and the faults that may affect them.

What is an Airbag?

Simply put, an airbag is a specially crafted bag made of durable materials. This bag inflates automatically at an extremely high speed in front of the passengers to protect them from colliding with the solid parts of the car, which could result in serious injuries, including fatalities.

Airbags are strategically placed in various locations to protect passengers from different angles. The number of airbags may vary by the manufacturer, but generally, cars include:

  • Front airbags to protect front-seat passengers from colliding with the front windshield.
  • Side airbags to protect passengers from side collisions.
  • Curtain airbags located at the car’s ceiling to protect passengers’ heads in the event of a rollover.
  • Knee airbags to protect passengers’ legs, particularly the knees, which are most susceptible to injuries in accidents.

When Does the Airbag Deploy?

These airbags are connected to precise sensors that determine the severity of the collision. Upon detecting an impact, a small explosion of nitrogen gas occurs, rapidly inflating the airbags. The airbags are activated within 0.025 seconds for moderate-impact collisions and within 0.015 seconds for severe-impact collisions. Once the airbags inflate in a traffic accident, they become unusable and should be replaced with new ones.

Common Airbag Faults

Airbag faults can result from various reasons, and drivers should be aware of them through regular inspections. Some of the main causes include:

  • Damage to the wires and connections of the airbag system.
  • Malfunctions in the sensors connected to the system.
  • Issues with the computer governing the system.
  • Damage to the airbags themselves.
  • Problems with seat belts.
  • Disconnection of the iron wire inside the steering wheel connected to the airbag.

These faults can be detected during regular inspections by connecting a specific device to the car’s computer and examining various faults in the car, including the airbag system. Drivers may also be alerted to a malfunction by the illumination of the airbag light on the instrument panel. In such cases, drivers should visit a maintenance center to address the issue and avoid serious injuries in accidents.

In this article, we provided you with a set of information about airbags that may be useful in the future. We discussed the types of airbags in cars, explained when airbags deploy, and answered some common questions related to airbags, focusing on the airbag light in the car and faults in this system.
