This document discusses the components and basic mechanism of an airbag inflation system. It describes how an airbag consists of a flexible envelope that inflates rapidly during a collision to prevent occupants from hitting hard interior objects. The key components that enable this are an accelerometer sensor, airbag control unit, nylon fabric, and inflation device. Upon impact, the sensor triggers the control unit to release gas from the inflation device, causing the nylon bag in the steering wheel or above the glove compartment to inflate within 0.05 seconds and cushion the occupant from impact.
