In Simple Terms
What it is
A service airbag is a safety feature in cars designed to protect passengers during a collision. Think of it like a cushion that instantly inflates when a crash happens, creating a soft barrier between you and the hard parts of the car, like the steering wheel or dashboard. It’s part of a larger system that includes sensors and a mechanism to fill the bag with gas in a split second.
Why people use it
The main reason is safety. Without an airbag, a sudden stop in a crash could throw you forward, leading to serious injuries. The airbag acts like a catcher’s mitt in baseball—it softens the impact and spreads out the force, reducing the risk of harm. It’s especially helpful in head-on collisions or side impacts where your body might hit something hard.
Basic examples
If a car hits a tree, the airbag pops out to prevent the driver’s head from slamming into the steering wheel.
In a side collision, side airbags (often in the doors or seats) inflate to protect your torso from the door or window.
For passengers in the front seat, the dashboard airbag stops them from hitting the windshield or hard surfaces.
Airbags work alongside seatbelts, which keep you in place, while the airbag cushions the blow. Together, they’re like a team—one holds you back, the other catches you. Modern cars even have airbags for knees or rear passengers, making rides safer for everyone.

Technical Details
What it is
A service airbag is a specialized type of airbag designed for use in automotive repair and maintenance environments. It falls under the category of safety and lifting equipment, primarily used to support or lift vehicle components during servicing. Unlike conventional airbags in vehicles, which are safety devices for crash protection, service airbags are pneumatic tools that provide controlled lifting force.
How it works
Service airbags operate using compressed air to inflate a durable rubber or polyurethane bladder. When connected to an air supply, the bladder expands, creating a lifting force that raises or stabilizes heavy vehicle parts. The inflation is controlled via a regulator or valve, allowing precise adjustment of height and pressure. Some advanced models include pressure sensors or automatic shut-off mechanisms to prevent overinflation.
