Durability to the force applied to 240 can be further improved.
이와 같이 구성된 에어백의 작동을 설명하면, 차량이 충돌을 하면 충격센서가 이를 감지하고 제어부에 신호를 보내고, 제어부는 다시 에어백 모듈의 인플레이터에 신호를 보내는데, 인플레이터 내에 있는 화약에 점화 전류가 흐르면 화약이 점화되고 이어 점화제가 연소되며 그 열에 의하여 가스발생제가 연소하면서 가스가 상기 제1가스유입부(220)와 제2가스유입부(221)로 급속히 유입된다. In this case, when the vehicle collides, the impact sensor detects the signal and sends a signal to the controller, and the controller sends a signal to the inflator of the airbag module. After the ignition, the ignition agent is burned, and the gas is burned by the heat, and the gas is rapidly introduced into the first gas inlet 220 and the second gas inlet 221.
가스의 급속한 유입으로 상기 에어쿠션부(230)가 팽창되고, 인스트루먼트패널에 형성된 에어백커버(미도시)가 개방되어 상기 에어쿠션부(230)는 조수석에 있는 탑승객이 관성력에 의하여 앞으로 튀어나와 자동차의 인스트루먼트패널이나 앞 유리에 부딪치는 속도보다 더 빨리 부풀어오르게 되는데 이때 상기 테더부(240)가 상기 에어쿠션부(230)의 형상을 유지시켜 탑승객을 더 안전하게 보호하게 된다.The air cushion unit 230 is expanded due to the rapid inflow of gas, and the air bag cover (not shown) formed in the instrument panel is opened, so that the air cushion unit 230 protrudes forward by the inertia force of the passenger. The swelling faster than the speed that hits the instrument panel or the windshield, the tether portion 240 maintains the shape of the air cushion portion 230 to protect the passengers more securely.
