Abstract
본 고안은 삽입식 운전자 에어 백, 특히 보유체를 커버의 지지보스에 탄착결합시킬 수 있는 운전자 에어 백 유니트에 관한 것이다.The present invention relates to an insertable driver air bag, in particular a driver air bag unit capable of rigidly coupling the retainer to the support boss of the cover.
종래에는 커버와 보유체를 리벳트 등의 하드웨어를 사용해 조립하였기 때문에 원가, 중량, 공정, 품질면에서 문제의 소지가 있었는 바 본 고안은 이를 개선하기 위하여 커버(1)의 연결보스(4)하단 양쪽면에 다수개의 탄착구멍(5)을 형성하고, 인플레이터(7)와 에어 백(8)이 중앙에 설치되는 보유체(2)의 플렌지(6) 양쪽면에 다수개의 탄착돌기(9)를 갖느 브래킷(10,10')을 각각 용접하여 상기 탄착돌기(9)가 연결보스(4) 외측에서 상기 탄측구멍(5)에 탄착결합되도록 한 것이다.Conventionally, since the cover and the retainer were assembled using hardware such as rivets, there was a problem in terms of cost, weight, process, and quality. The present invention provides a lower end of the connecting boss 4 of the cover 1 to improve this. A plurality of impact holes 5 are formed on both sides, and a plurality of impact protrusions 9 are provided on both sides of the flange 6 of the retainer 2 in which the inflator 7 and the air bag 8 are installed at the center. Each of the brackets 10 and 10 'is welded so that the impact projection 9 is coupled to the impact hole 5 at the outside of the connecting boss 4.

본 고안은 운전자 에어 백, 특히 보유체를 커버의 지지보스에 탄착결합시킬 수 있는 운전자 에어 백 유니트에 관한 것이다.The present invention relates to a driver airbag unit, in particular a driver airbag unit capable of rigidly coupling the retainer to the support boss of the cover.
종래의 운전자 에어 백 유니트는 제3도에 도시하는 바와 같이 중앙에 인플레이터(21)와 에어 백(22)이 설치되는 보유체(23)의 가장자리를 노치(24)를 중심으로 양측으로 개방될 수 있는 커버(25)의 보스(26)에 리벳트(27) 또는 스크류 등을 사용하여 고정토록 하고 있다.In the conventional driver airbag unit, as shown in FIG. 3, the edges of the retainer 23 in which the inflator 21 and the airbag 22 are installed in the center can be opened to both sides about the notch 24. The bosses 26 of the cover 25 are fixed to each other using a rivet 27 or a screw.
이렇게 할 경우 연결보스(26)와 보유체(23)의 가장자리에 각각 약 10군데의 구멍을 뚫어야 하고 각각의 구멍간을 맞추어 리벳팅 작업을 하여야 하는 등 조립공정이나 원가면에서 불리하고 중량이 늘어나는 문제가 있으며 불량을 상승의 원인이 되고 있었다.In this case, about 10 holes must be drilled at the edges of the connecting boss 26 and the retainer 23, and the riveting work must be carried out in accordance with each hole. There was a problem and the defect was causing the rise.
본 고안은 커버를 조립할 때 리벳트 등 별도의 하드웨어를 사용하지 않고 커버의 연결보스를 보유체에 밀어넣어 빠져나오지 않도록 하는 삽입식 운전자 에어 백 유니트를 제공하는데 그 목적이 있는 것이다.The object of the present invention is to provide an insertable driver airbag unit that does not push out the connecting boss of the cover to the holder without using separate hardware such as rivets when assembling the cover.
본 고안은 상기 목적을 달성하기 위하여 커버의 연결보스하단 양쪽면에 다수개의 탄착구멍을 형성하고, 인플레이터와 에어 백이 중앙에 설치되는 보유체의 플렌지 양쪽면에 다수개의 탄착돌기를 갖는 브래킷을 각각 용접하여 상기 탄착돌기가 연결보스 외측에서 상기 탄착구멍에 탄착결합되도록 한 것이다.The present invention forms a plurality of impact holes on both sides of the lower end of the connecting boss of the cover to achieve the above object, and each of the brackets having a plurality of impact projections on both sides of the flange of the retainer in which the inflator and the air bag are installed in the center By doing so, the impact protrusions are coupled to the impact holes outside the connection boss.
이하 실시예 도면에 의하여 설명한다.A description with reference to the following drawings.
제1도 및 제2도는 본 고안의 실시예를 나타낸 것으로서, 부호 1은 커버이고, 2는 보유체이다.1 and 2 show an embodiment of the present invention, where 1 is a cover and 2 is a retainer.
커버(1)는 중간의 노치(3)를 중심으로 양쪽으로 개방될 수 있는 것으로서 하부의 연결보스(4) 하단 양쪽면에는 사각의 탄착구멍(5)이 다수개 형성되어 있다.The cover 1 is open to both sides of the notch 3 in the middle, and a plurality of square impact holes 5 are formed on both sides of the lower ends of the connecting boss 4.
보유체(2)는 상기 커버(1)의 연결보스(4)내에 끼워질 수 있는 플랜지(6)가 가장자리에 형성된 금속재질로서 중앙에는 인플레이터(7)가 고정설치되고 인플레이터(7)상에는 에어 백(8)이 설치되어 있다. 이 보유체(2)의 플랜지(6) 양쪽외면에는 다수개의 탄착돌기(9)가 각각 판금가공에 의하여 형성되는 브래킷(10,10')이 용접된다.The retainer 2 is made of a metal material having a flange 6 formed at an edge thereof, which can be fitted into the connecting boss 4 of the cover 1, and an inflator 7 is fixedly installed at the center thereof and an air bag is mounted on the inflator 7. (8) is installed. Brackets 10 and 10 ', each of which has a plurality of impact projections 9 formed by sheet metal processing, are welded to both outer surfaces of the flange 6 of the retainer 2.
이 브래킷(10,10')은 탄착돌기(9)가 형성되는 부위가 플랜지(6)면으로 부터 연결보스(4)의 두께만큼 돌출되어 있고 양쪽가장자리는 플랜지(6)면에 용접되어 있다.The brackets 10 and 10 'protrude from the surface of the flange 6 to the thickness of the connecting boss 4 from which the impact projection 9 is formed, and both edges are welded to the flange 6 surface.
따라서 하나의 운전자 에어 백 유니트를 이루기 위해서는 커버(1)를 인플레이터(7)와 에어 백(8)이 설치된 보유체(2)에 조립하여야 한다.Therefore, in order to achieve one driver airbag unit, the cover 1 must be assembled to the retainer 2 provided with the inflator 7 and the airbag 8.
이러한 조립은 커버(1)의 연결보스(4)를 보유체(2)의 플랜지(6)외면과 맞추어 삽입하면 달성된다.This assembly is achieved by inserting the connecting boss 4 of the cover 1 in conformity with the outer surface of the flange 6 of the retainer 2.
이때 연결보스(4)가 브래킷(10,10')과 플랜지(6)사이로 들어가면서 각각의 탄착돌기(9)가 각각의 탄착구멍(5)에 동시에 탄성적으로 끼워져 결합되면 빠져나오지 않게 되는 것이다.At this time, as the connecting boss 4 enters between the brackets 10 and 10 'and the flange 6, each impact protrusion 9 is elastically fitted to each impact hole 5 at the same time so as not to escape.
이와 같은 본 고안은 커버가 보유체에 삽입식으로 조립되기 때문에 종래에 비하여 원가절감. 중량감소. 부품수 감소에 따른 사양관리 및 조립용이 등의 효과가 있는 것이다.The present invention as described above, because the cover is assembled to the holder in the cost reduction compared to the conventional. Weight reduction. It is effective in specification management and assembly as the number of parts decreases.
