The Airbag Housing serves as the structural foundation that integrates, protects, and rigidly anchors the core components—including the airbag (cushion), inflator (gas generator), and initiator—to designated locations like the steering wheel center or dashboard, ensuring the system's functional reliability by safely containing the explosively generated high-pressure gas upon collision and guaranteeing the precise, controlled deployment of the airbag without structural failure, which is crucial for occupant safety; furthermore, in line with vehicle lightweighting trends, materials are evolving from steel to high-strength, impact-resistant composites and reinforced plastics to maintain optimal performance.
