Learn about airbags and airbag safety
Since their development in the late 1980s, air bags have saved thousands of lives by protecting drivers and passengers during frontal crashes.
Front air bags are located in the steering wheel to protect the driver, and in the dashboard of most cars to protect passengers. Front air bags are not designed to protect vehicle occupants in side and rear impact or rollover collisions. Because air bags (and seat belts) were designed to protect average-sized adult males and NOT children, they can be extremely dangerous to infants or young children seated in front of them. According to research conducted by CHOP, children exposed to air bags during a crash are twice as likely to suffer a serious injury.
Children younger than 13 years are safest when placed in the back seat of a vehicle, according to the American Academy of Pediatrics (AAP). Other air bag safety rules to follow include:
Find out what you need to know about air bags when buying a used car.
Side torso airbags, designed to protect the pelvis, abdomen and rib cage, usually come out of the seat between the seat occupant and the door. Side air bags designed to protect the head, also known as curtain airbags, come out of the roof above the windows.
While side air bags are more common in the front seats of a vehicle, some newer cars also have side air bags in the rear seats. Check your car owner’s manual and look for labels on the sides of the seats.
Side air bags can help prevent injuries to adults in side crashes, but may be dangerous to children who are not properly restrained or are leaning against the door. Although side air bags are smaller than front air bags and inflate with much less force, injury could occur if your child’s head is too close to the air bag.
The automotive industry has developed specific test protocols to minimize the risk of injury from side air bags to children seated next to them. Although this testing is voluntary, vehicles that complete it successfully receive a special designation in NHTSA’s Buying a Safer Car for Child Passengers brochure. Access this brochure, and see if your vehicle was tested for and meets side air bag standards.
Here are some suggestions to help protect your child if your car has front- or rear-seat side air bags:
The government requires that vehicles without a back seat, such as pickup trucks, have an air bag on/off switch. If a child must ride in this type of vehicle, be sure to turn the air bag off. It’s important to remember to turn the air bag on again when an adult or teenager rides as a passenger.
In addition, some consumers with special circumstances may need to have an air bag on/off switch installed in their cars. The National Highway Traffic Safety Administration (NHTSA) has made some exceptions for these consumers. Learn more about NHTSA’s recommendations for deactivating air bags.
The air bag system includes the air bag itself, a crash sensor, and a diagnostic unit that controls the system. In a head-on crash, the vehicle's front-end crushes, absorbing crash energy and creating a softer stop for restrained occupants. An unrestrained or loosely restrained person will continue to move forward at the same speed until hitting the car's interior. Properly restrained occupants come to a more gradual stop, along with the vehicle. Air bags also help drivers and passengers come to a more gradual stop, preventing contact with a vehicle’s interior and spreading crash forces more broadly across the body.
As the crash occurs, sensors send a signal to the air bag. A chemical reaction produces harmless nitrogen gas that fills the bag and pushes it out of its compartment. The whole process takes only about 1/20th of a second. (Half the time it takes you to blink!) The air bag then starts to deflate as the gas disappears, absorbing crash energy.
Engineers have worked hard to improve air bags to increase safety. These improved versions, known as second generation or depowered air bags, are still not designed for children. Children are best protected in the rear seat. Having advanced air bags in your vehicle does not mean kids can ride in the front seat. Children younger than 13 years are best protected in the rear seat.
The newest type of "advanced" air bags further reduces the risk of an airbag-related injury or death for adults. When a front-end crash occurs, advanced air bags inflate according to the seriousness of the crash, passenger size, sitting position, and distance from the air bag. Sensors note these conditions and automatically deploy or release the air bag at a higher or lower force or perhaps not at all.
