How the air bag system in cars protect the driver and the front passenger from injuries?

Injuries from car accidents result when this force is very large. Airbags protect you by applying a restraining force to the body that is smaller than the force the body would experience if it hit the dashboard or steering wheel suddenly, and by spreading this force over a larger area.

How do crumple zones protect people?

Crumple zones work by managing crash energy and increasing the time over which the deceleration of the occupants of the vehicle occurs, while also preventing intrusion into or deformation of the passenger cabin. This better protects car occupants against injury.

Where are the airbags on the steering wheel?

The driver airbag is the one mounted in the steering wheel that protects the driver in most crashes, including front, rear and side impacts [source: Autoliv: Driver ]. If the driver is flung forward in a crash, chances are that they will be up close and personal with the driver airbag.

When did side impact airbags become mandatory in cars?

Fatalities in head-on collisions have declined dramatically since the government mandated front airbags as standard equipment in 1991. That means side impacts have increased in relative importance as a vulnerability for drivers and passengers.

Are there any side curtain airbags for convertibles?

Recently, though, automakers are finding new ways to adapt side curtain technology specifically for niche applications, especially in high-risk vehicles. Drivers of convertibles and SUVs, for example, currently enjoy the benefits of side curtain protection and rollover-specific security.

How are airbags used to protect both drivers and passengers?

The airbags will protect both drivers and passengers from direct impact. After that, the gas will escape through these holes, which makes the airbag become smaller overtime for driver to get out. The ACU developers also have carefully calculated the inflation time.

Are there any side impact airbags in cars?

Some automotives feature side curtain airbags, but most vehicles offer no protection from side impact crashes besides the car door.

When do side curtain airbags inflate in a rollover?

Sensors that measure a vehicle’s sideways movement and tilting can detect if a rollover is about to occur, triggering deployment. These airbags typically inflate within the first 10-20 milliseconds of a rollover crash and can remain inflated longer than regular side curtain airbags (10 or more seconds) to protect during multiple-roll crashes.

Why do side impact air bags inflate so quickly?

Side-impact air bags inflate even more quickly since there is less space between the driver or passengers and the striking object, whether the interior of the vehicle, another vehicle, a tree, or a pole.
