When Do Car Airbags Deploy? Your Safety Guide

“Traffic accidents are like death knocking at your door,” a quote from Mr. Nguyen Van A, a long-time truck driver in Cau Giay, Hanoi, reminds us of the importance of road safety. One of the most crucial safety features in a car is the airbag. So, when do car airbags deploy and how do they work? Let’s delve into the details with Hanoi Truck.

Car Airbags – The Silent Guardians

What is a Car Airbag?

A car airbag is part of the vehicle’s passive safety system, designed like an inflatable cushion that automatically deploys in the blink of an eye during a sufficiently strong collision. It creates a protective barrier between the occupants and the car’s interior, minimizing injuries.

When Do Car Airbags Deploy?

Many people mistakenly believe that airbags are a “lifesaver” in all accident scenarios. However, in reality, airbags only deploy in moderate to severe frontal or angled collisions, specifically:

• Frontal Collisions: The car directly hits a wall, electric pole, tree, etc.
• Angle Collisions: The car is hit hard from the front left or right, creating a specific collision angle.

Note: Airbags will not deploy in the following cases:

• Minor Collisions: The impact force is insufficient to activate the airbag sensors.
• Rear or Side Impacts: Airbags are designed to protect occupants in frontal collisions.
• Vehicle Rollovers: Unless the rollover occurs after a frontal or angle collision.

The “Lightning-Fast” Mechanism of Car Airbags

Car airbags operate based on the principle of a “rapid chemical reaction” triggered by impact sensors. When a sufficiently strong collision occurs, the sensors transmit a signal to the airbag control unit. The control unit analyzes the data and activates the inflator to inflate the airbag in an extremely short time, only about 20-30 milliseconds, faster than the blink of an eye!

Types of Airbags in Cars

Currently, cars are equipped with various types of airbags, the most common being:

• Driver and Front Passenger Airbags: These are basic airbags, mandatory in cars.
• Side Airbags: Protect the sides of occupants during side impacts.
• Curtain Airbags: Protect the heads of occupants during rollovers.
• Knee Airbags: Reduce leg injuries for the driver and front passenger.

Car Airbags – Important Considerations

Airbag Placement

• Driver airbags are usually located in the steering wheel.
• Front passenger airbags are located in the dashboard in front of the passenger seat.
• Side airbags are integrated into the seatbacks or door panels.
• Curtain airbags are concealed in the car’s ceiling.

Airbag Safety

To ensure safety when airbags deploy, keep in mind:

• Always wear your seatbelt while the car is in motion.
• Adjust your seat to a safe distance from the steering wheel.
• Do not allow children to sit in the front seat or place a rear-facing child seat in the front passenger seat with an active airbag.
