What is an Airbag?
1 Answers
An airbag is a cushioning device that rapidly inflates when a vehicle experiences a collision and sudden deceleration, protecting occupants from impacting the interior of the vehicle. As a passive safety feature, airbags help reduce injuries caused by frontal impacts. The airbag consists of a flexible rubber capsule filled with compressed air or liquid medium, utilizing the compressibility of air and fluidity of water to provide elasticity. When a vehicle collides with an obstacle (primary collision), and subsequently when occupants collide with interior components (secondary collision), the airbag rapidly deploys a gas-filled cushion between these two events. This allows occupants to land on the cushion during inertial movement, thereby cushioning the impact and absorbing collision energy to mitigate occupant injuries.
