Description

Technical Field

[0001] This utility model belongs to the field of airbag technology, specifically relating to a rotary multi-air-path airbag inflation device. Background Technology

[0002] An airbag is a flexible rubber capsule filled with compressed air or water. It utilizes the compressibility of air and the fluidity of water to achieve elasticity. As an auxiliary feature for passive safety in vehicle vehicles, airbags are receiving increasing attention. A primary collision occurs when a car collides with an obstacle; a secondary collision occurs when the occupants collide with interior components. The airbag rapidly deploys after the primary collision but before the secondary collision, creating a gas-filled cushion that allows the occupants to "land on" the cushion as they move due to inertia, thus mitigating the impact and absorbing collision energy, reducing the severity of injury.

[0003] Currently, airbags need to be inflated during manufacturing, but general inflation equipment cannot effectively inflate multiple air passages, thus affecting their performance. Utility Model Content
