Airbag systems are safety devices in vehicles designed to inflate rapidly during a collision, providing a cushion for passengers. They work by using sensors to detect a crash and trigger the airbag deployment, which helps reduce the risk of injury by preventing occupants from hitting hard surfaces inside the car. Typically, airbag systems include front airbags, side airbags, and curtain airbags, each serving a specific purpose. Front airbags protect the driver and front passenger, while side and curtain airbags offer additional protection in side-impact collisions. These systems are an essential part of modern vehicle safety, contributing to overall occupant protection during accidents.
