Buick 2006 manual What Makes an Airbag Inflate?, How Does an Airbag Restrain?

Your vehicle may or may not have a side impact airbag. See Airbag System on page 1-57. Side impact airbags are intended to inflate in moderate to severe side crashes. A side impact airbag will inflate if the crash severity is above the system’s designed “threshold level.” The threshold level can vary with specific vehicle design. Side impact airbags are not intended to

inflate in frontal or near-frontal impacts, rollovers or rear impacts. A side impact airbag is intended to deploy on the side of the vehicle that is struck.

In any particular crash, no one can say whether an airbag should have inflated simply because of the damage to a vehicle or because of what the repair costs were. For frontal airbags, inflation is determined by what the vehicle hits, the angle of the impact, and how quickly the vehicle slows down. For side impact airbags, inflation is determined by the location and severity of the impact.

What Makes an Airbag Inflate?

In an impact of sufficient severity, the airbag sensing system detects that the vehicle is in a crash. The sensing system triggers a release of gas from the inflator, which inflates the airbag. The inflator, the airbag and related hardware are all part of the airbag modules. Frontal airbag modules are located inside the steering wheel and instrument panel. For seating positions with side impact airbags, there are also airbag modules in the side of the seatbacks closest to the door.

How Does an Airbag Restrain?

In moderate to severe frontal or near frontal collisions, even belted occupants can contact the steering wheel or the instrument panel. In moderate to severe side collisions, even belted occupants can contact the inside of the vehicle. The airbag supplements the protection provided by safety belts. Airbags distribute the force of the impact more evenly over the occupant’s upper body, stopping the occupant more gradually. But the frontal airbags would not help you in many types of collisions, including rollovers, rear impacts, and many side impacts, primarily because an occupant’s motion is not toward the airbag. Side impact airbags would not help you in many types of collisions, including many frontal or near frontal collisions, and rear impacts, primarily because an occupant’s motion is not toward those airbags.
