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.
