The airbag device is provided with a rotation means which allows the steering wheel 20 to rotate downward with respect to the steering shaft 10 while the airbag 30 is deployed to the front of the driver due to the collision during the high speed driving of the vehicle. The airbag 30 is configured to deploy in the chest of the driver seat occupant.

그리고 상기 회전수단은 상기 스티어링축(10)의 단부에 마련되는 제1힌지부(11)와, 상기 스티어링휠(20)의 단부에 제2힌지부(21)가 마련되며, 상기 제1,제2힌지부(11,21)를 회전가능하게 결합시키는 힌지축(21a)에 의해 상기 스티어링축(10)과 스티어링휠(20)이 결합된다.The rotating means may include a first hinge portion 11 provided at an end of the steering shaft 10 and a second hinge portion 21 at an end of the steering wheel 20. The steering shaft 10 and the steering wheel 20 are coupled by a hinge shaft 21a which rotatably couples the two hinge parts 11 and 21.

또한 상기 제1,2힌지부(11,21)에 각각 대응되는 슬라이드홈(40)이 형성되고 그 슬라이드홈(40)에 슬라이딩 가능하게 결합되어 상기 스티어링휠(20)을 스티어링축(10)에 고정시키는 고정핀(50)이 구비되며, 상기 에어백(30)의 전개시 상기 고정핀(50)을 상기 슬라이드홈(40)으로부터 취출시키는 취출수단을 구비하여 이루어진다.In addition, slide grooves 40 corresponding to the first and second hinge parts 11 and 21 are formed and slidably coupled to the slide grooves 40 so that the steering wheel 20 is connected to the steering shaft 10. Fixing pins 50 are provided to fix the air, and the air outlet 30 is provided with a drawing means for taking out the fixing pins 50 from the slide grooves 40.

그리고 상기 취출수단은 상기 스티어링휠(20)에 에어백(30)의 전개와 함께 회전되는 도어(31a)를 가지며, 상기 도어(31a)와 상기 고정핀(50)을 연결시키는 와이어(50a)를 마련하여서, 상기 도어(31a)의 회전시 상기 고정핀(50)이슬라이드홈(40)으로부터 취출되도록 된 구조를 가진다.And the take-out means has a door (31a) that is rotated with the deployment of the airbag 30 in the steering wheel 20, and provides a wire (50a) connecting the door (31a) and the fixing pin (50) Thus, when the door 31a is rotated, the fixing pin 50 has a structure to be taken out from the slide groove 40.

그리고 미설명부호 31b는 에어백 도어의 절개부(31b)로 상기 에어백(30)이 전개되면서 이 도어(31a)가 양쪽으로 열리면서 상기 와이어(50a)를 끌어당기면 상기 고정핀(50)이 상기 슬라이드홈(40)으로부터 분리된다.In addition, the reference numeral 31b indicates that the fixing pin 50 is the slide groove when the airbag 30 is opened to the cutout portion 31b of the airbag door and the door 31a is opened to both sides to pull the wire 50a. Separated from 40.

한편, 상기 고정핀(50)의 일단에 그 일단이 결합되는 와이어(50a)는 그 타단을 상기 에어백(30)의 팽창을 방해하지 않도록 상기 에어백도어(31a) 외의 적당한 위치에 결합시켜서, 상기 에어백(30)의 전개와 함께 상기 고정핀(50)을 상기 슬라이드홈(40)으로부터 용이하게 취출되도록 하는 것이 바람직하다.On the other hand, the wire 50a, one end of which is coupled to one end of the fixing pin 50, couples the other end to a suitable position other than the airbag door 31a so as not to interfere with the expansion of the airbag 30, and thus the airbag. It is preferable that the fixing pin 50 is easily taken out from the slide groove 40 together with the development of the 30.

상기와 같은 구성을 가지는 본 발명에 따른 에어백장치는 다음과 같은 효과를 가진다.The airbag apparatus according to the present invention having the configuration as described above has the following effects.

즉, 차량의 고속주행중 충돌시에 에어백(30)이 전개됨과 동시에 상기 스티어링휠(20)이 상기 스티어링축(10)에 대해 하방으로 회전되도록 한 회전수단에 의해서 상기 에어백(30)이 탑승자의 가슴부분으로 전개되도록 하므로서 운전자의 안전이 보장된다.That is, the airbag 30 is deployed at the time of collision during the high speed driving of the vehicle and the airbag 30 is driven by the rotation means such that the steering wheel 20 is rotated downward with respect to the steering shaft 10. The driver's safety is ensured by being deployed in parts.

한편, 이상에서 설명한 바와 같은 본원 발명은 본원 발명의 기술적 사상의 범위를 벗어나지 아니하고 다양한 변형 실시가 가능하다.On the other hand, the present invention as described above is capable of various modifications without departing from the scope of the technical spirit of the present invention.
