- The sensor is the device that tells the bag to inflate. Inflation happens when there is a collision force equal to running into a brick wall at 10 to 15 miles per hour (16 to 24 km per hour). A mechanical switch is flipped when there is a mass shift that closes an electrical contact, telling the sensors that a crash has occurred. The sensors receive information from an accelerometer built into a microchip.
- The airbag's inflation system reacts sodium azide (NaN3) with potassium nitrate (KNO3) to produce nitrogen gas. Hot blasts of the nitrogen inflate the airbag.

What is a driver airbag squib?
This is an educated guess... A squib is a firework (aka pyrotechnic) and most airbag designs are inflated by pyrotechnic means. Therefore I believe the squib is the charge that triggers airbag inflation.
Can a car be driven right after the airbag has inflated or does it have to be taken to a shop?
It can be driven but unless the airbag is stuffed back in or cut out it will get in the way while steering. Not to mention you won't have an airbag if you get into another front end collision.
What chemical reaction occurs when an airbag is inflated?
When an airbag is inflated, a chemical reaction involving the rapid decomposition of sodium azide (NaN3) occurs. This reaction produces nitrogen gas (N2) which rapidly fills the airbag, causing it to inflate quickly to protect the occupants of the vehicle in the event of a collision.
What is airbag in fish useful for?
A fish's 'swim bladder' can be inflated or deflated depending on if the fish wants to go up or down in the water.
How was the airbag originally used in space?
The airbag was originally used in space to cushion the landing of spacecraft on Mars. The airbag system wrapped around the spacecraft and inflated upon impact to absorb the shock and protect the payload during landing. This technology was first used on the Mars Pathfinder mission in 1997.
How does the size of an airbag affect its performance?
The larger the size of the airbag allows more nitrogen (that's right nitrogen not air) for your head to be able to cushion the impact of the crash. However the airbag is not inflated to the max at the time your head comes in contact with it. This is because the airbag will be hard from the amount of nitrogen in the airbag so it deflates a little to make it softer.
What gas law can be used to calculate the inflation of an airbag?
n = inflated moles of gas n= [p*V] / [R*T] with R = constant, and in an airbag mostly T = constant (25 oC = 298K) meaning: [p1*V1] / n1 = [p2*V2] / n2
Is the US inflated?
yes the US is inflated
Does blood keep your inflated?
Does blood keep you inflated
What does Lung fields hyper inflated means?
Hyper means over normal. Inflated means blown up. The lungs are over-inflated.
When was Airbag created?
Airbag was created in 1973.
How much does an inflated car tire weigh?
The same as a tire that has not been inflated.
