the inertia switch locks the ignition. this can occur without the airbags being deployed. if your car wont start it is a good possibility that the inertia switch has locked the ignition. the switch is usually located on the passenger side of the vehicle behind the kick panel on the right side
there is no max speed for airbag deployment there is a minimum speed but that speed depends on make of car and airbag
replace them, they are engineered to lock up if air bags are deployed
an electrical signal up to the airbag and it deploys
no protection
Airbag deployment can happen at any speed. It's not about the speed, but rather the impact that the car feels to deploy the bags.
Airbag deployment is a physical change. It involves the rapid release of gas (usually from a chemical reaction) that inflates the airbag, without changing the chemical composition of the materials involved.
In the proper type of collision, the airbag could go off if you are sitting still.
The force of the collision has to be great enough
I don't think they have a maximum, only a minimum.
no protection
There is an airbag assy on the steering wheel and one on the dashboard on passenger side. they are assy. that get replaced.
The force of the collision has to be great enough
