Abstract

본 발명은 자동차의 에어백에 관한 것으로, 자동차의 조향 핸들 적소에 내설되며 자동차가 주행중 충돌했을 때 충돌의 심한 정도를 감지하여 에어백 전개 알고리즘의 판단에 따라 가스 발생기에 전기적 신호를 발생시켜 생성된 가스로 충만되는 부직포로 구성된 1차 에어백, 상기 1차 에어백의 일측에 구비되며, 상기 1차 에어백으로 충만되는 가스의 일부가 바이패스 되는 바이패스 수단, 상기 바이패스 수단으로 통과하는 일부의 가스로 2차 에어백을 팽창시키며, 상기 1차 에어백이 배기구로 내부 가스 배출에 따른 수축시에도 바이패스 수단에 의해 부풀어진 2차 에어백은 가스의 배출 및 누출이 없이 충만된 상태를 유지하고 있기 때문에 예상치 못한 2차 충돌로부터 운전자를 보호할 수 있다.The present invention relates to an airbag of a vehicle, which is inherent in a steering wheel of a vehicle and detects the severity of a collision when the vehicle collides while driving, and generates an electrical signal to a gas generator according to a decision of an airbag deployment algorithm. A primary air bag composed of a nonwoven fabric to be filled, provided on one side of the primary air bag, the bypass means that a portion of the gas filled with the primary air bag is bypassed, the secondary part of the gas passing through the bypass means Unexpected secondary because the primary airbag inflates, and the secondary airbag inflated by the bypass means even when the primary airbag is deflated due to the discharge of the internal gas into the exhaust port, remains full without the release and leakage of gas. You can protect the driver from collisions.
