It cushions the fall.
The airbag reduces the deceleration experienced on impact. In terms of acceleration, this means that the airbag has lowered the rate at which the downward acceleration decreases.If a falling person hits solid ground then their velocity goes from high to zero almost instantaneously. This means that the downward acceleration has changed very quickly. The airbag increases the time in which it takes the velocity to fall to zero. This is the same as saying it reduces the deceleration.Of course an airbag has the additional benefit of being soft relative to the ground, but simply considering acceleration/deceleration, reducing this lessens the harm done to the person. A high rate of acceleration/deceleration by itself can cause death/serious injury as a person's internal organs rupture due to the sudden collision with the other parts of the body (bones for instance). An airbag is helping by reducing the rate of change of the downward acceleration to a more survivable level. The force on the person is therefore lowered on "landing".
Yes, they can kill you. If you are too small, the airbag can suffocate you.
the extremely rapid inflation of airbags. not wearing a seatbelt when an airbag inflates. being positioned incorrectly in the seat when an airbag inflates. if this question is for study island the answer is all of the above.
inertia
An airbag works by increasing the time it takes to reduce the drivers momentum; they are thus actually designed to deflate slowly (in relative terms). A longer change means a lower impulse, and therefore less force acting on the person. This lowers the risk of a serious blunt-force injury and is why an airbag is safer.
To prevent injury by cushioning the driver and passengers from impact.
You need to have someone with a scan tool check the airbag system for trouble codes. The airbag system is not a place for do it your selfers.
A squib is someone who comes from a magical family who is non-magical.
This sounds like the "airbag symbol" to me: http://images.google.com/images?q=airbag symbol
It's a problem with the contact inside the steering wheel. If the vehicle has an air bag, don't touch it. Take it to someone who knows how to prevent an airbag from accidentally going off.
If you mean passenger side airbag? well, you don't have to. Personally, I have my disengaged at all times, unless someone is sitting in the passenger seat.
Airbag code 19 indicates that the RCM has detected a circuit problem with the driver's side airbag circuit. That might mean a connector or a clock spring fault or the airbag or RCM has failed electrically. It is STRONGLY recommend to leave airbag system repairs to someone with the proper training and equipment as it can be hazadrous to your health to try and repair it youself.
Are you trying to kill someone?
There is a problem with the safety restraint system. Fix or have it fixed immediately. The air bags could deploy when not expected or not deploy when needed. There are several airbag sensors (in the bumper and air bag). They usually fail due to a short to power or ground.
The airbag service light is on because it has detected a malfunction. The malfunction may prevent your airbag from deploying properly in a crash, so it is important to trace the cause and repair it. The best approach is to take the vehicle to a competent repair shop where they will connect a scan tool to the airbag module and identify the malfunction. Many airbag system malfunctions are covered by the vehicle warranty, so the dealer may be the best place to start.
Doable in theory but not in reality. Getting a steering wheel with an airbag is no big deal, but then you need the electronics that'll tell the airbag when to deploy. And I haven'ty seen those for sale anywhere. Maybe you can find someone who'd be willing to transplant the whole airbag system from another car if you could pay them enough for it.
No. There is no switch or key lock feature to manually turn off the passenger side airbag. If there is no one in the seat it will automatically turn off.The seat has a sensor that senses when someone is sitting in the seat.
