Airbags are safety devices installed in vehicles to protect passengers during a collision. They are designed to inflate rapidly upon impact, creating a cushion that reduces the risk of injury by preventing occupants from hitting hard surfaces inside the car. Airbags are typically located in the steering wheel, dashboard, and side panels. When a crash occurs, sensors detect the sudden deceleration and trigger the airbag deployment. The airbag inflates with gas, usually from a chemical reaction, and then deflates quickly after the impact. This technology has significantly improved vehicle safety and is now a standard feature in most modern cars.
