Study Notes

Airbag Mechanics and Functionality

Airbags are mandatory safety devices in all new vehicles, designed to inflate rapidly during collisions.
Inflation occurs within 25 to 50 milliseconds after a collision is detected, providing immediate protection.
They deflate within a matter of seconds to avoid becoming a hazard to vehicle occupants.
During deflation, tiny holes open in the airbag's interior to release gas and facilitate a controlled deflation process.

Impact and Energy Absorption

Airbags effectively act as a brake, counteracting the driver’s momentum when deployed.
They can bring a driver traveling at 60 miles per hour to a complete stop by absorbing forward momentum.
The contracting airbag absorbs kinetic energy, reducing the risk of injury upon impact.

Safety and Injury Prevention

Proper deployment ensures that occupants are protected from injuries to vulnerable body parts such as the forehead, chin, and neck.
Timely inflation is crucial; airbags must be fully inflated before occupants move too close to them to minimize injury risk.
The deployment decision for frontal collisions is made between 15 and 50 milliseconds, emphasizing the system's responsiveness.

Composition and Deployment

Airbags are made of nylon and filled with harmless gas produced from a chemical reaction during deployment.
After contact with a person's head, gas escapes from the edges of the bag, allowing controlled cushioning.
For optimal safety, complete rupture of the airbag is required after a vehicle crash to ensure it cannot reinflate dangerously.
