7 : 알루미늄라이너 8 : FRP7: aluminum liner 8: FRP

본 고안은 자동차 안전장치인 압축가스식 에어백(Air Bag)용 인플레터(Inflator)구조에 관한 것으로서, 특히 인플레터의 프레셔용기를 경량화 시킬 수 있도록 한 인플레터 구조에 관한 것이다.The present invention relates to an inflator structure for a compressed gas-type air bag which is a vehicle safety device, and more particularly, to an inflator structure capable of lightening the pressure vessel of the inflator.

주지된 바와 같이 자동차의 안전장치인 인플레터는 화학식이나 하이브리드(Hybrid)식의 형태로서 하이브리드식은 센서의 전기적인 신호에 의해 뇌관을 점화로 가스발생제가 가스를 발생시켜 에어백을 팽창시키도록 되어 있다.As is well known, the inflator, which is a safety device of a vehicle, is in the form of a chemical formula or a hybrid, and the hybrid type is configured to inflate an airbag by generating a gas by igniting a primer by an electrical signal of a sensor.

그러나 종래의 하이브리드식 에어백에 사용되는 인플레터(11)는 스틸(Steel)이나 주철재로 프세셔용기를 제작하여 내부에 압착공기와 가스발생제를 저장할 수 있는 형태로서 충돌감지센서의 전기적인 신호에 의해 충돌을 감지하면 스퀴브(15)에 전류가 흘러 점화되면서 가스발생제를 얻어 에어백을 팽창시킨다.However, the inflator 11 used in the conventional hybrid airbag is made of steel or cast iron container to store the compressed air and the gas generator therein, the electrical signal of the collision detection sensor When the collision is detected by the current flows through the squib 15 to ignite to obtain a gas generating agent to inflate the airbag.

상기와 같은 인플레터(11)는 프레셔용기(12)가 주철이나 스틸로 제작되어 있기 때문에 중량이 무겁고, 가스 발생제 연소시 소음과 열이 많이 발생하는 문제점이 야기되었다.Since the pressure vessel 12 is made of cast iron or steel, the inflator 11 has a heavy weight and causes a lot of noise and heat when the gas generator is burned.

본 고안은 상기한 종래의 제문제점을 해결하기 위하여 안출된 것으로 인플레터의 프레셔용기를 FRP와 알루미늄라이너로 형성하여 소음 및 열발생이 적도 경량화 인플레터 제작이 용이하고 고압충진을 가능하게 하려는 것이 그 특징이다.The present invention was devised to solve the above-mentioned problems. The pressure vessel of the inflator is formed of FRP and aluminum liner to make the inflator easy to manufacture and to make high pressure filling with low noise and heat generation. It is characteristic.

상기의 목적을 달성할 수 있는 본고안은 첨부된 도면에 의하여 상세히 설명하면 다음과 같다.The subject matter that can achieve the above object is described in detail by the accompanying drawings as follows.

제2도 및 제3도에서와 같이 프레셔용기(2)의 입구측에 하우징플레트(3)를 결합하되, 하우징플레트(3)의 내부에는 중앙에 충돌감지센서와 연결된 상태로 스퀴브(5)가 설치되고, 전방 주연에 스크린(6)이 설치된 스퀴브 하우징(4)을 설치하여서 된 인플레터(1)에 있어서, 상기 인플레터(1)의 프레셔용기(2)을 얇은 알루미늄라이너(7)위에 FRP(8)를 필라민트 와인당(Filament Winding)하여 압축가스만을 사용할 수 있도록 구성된 것이다.As shown in FIGS. 2 and 3, the housing plate 3 is coupled to the inlet side of the pressure vessel 2, but the squib (with a collision sensor in the center of the housing plate 3) is connected to the center. In the inflator 1, which is provided with a squib housing 4 provided with a screen 6 on the front circumference of the front periphery, the pressure vessel 2 of the inflator 1 is made of a thin aluminum liner. 7) FRP (8) on the Filament Winding (Filament Winding) is configured to use only compressed gas.

이와 같이 구성된 본 고안은 충돌감지센서에서 차량충돌을 감지하면 하우징플레이트(3) 내부에 설치된 스퀴브하우징(4)의, 스퀴브(5)가 전기적 신호를 받아 점화된다.According to the present invention configured as described above, when the collision detection sensor detects a vehicle collision, the squib 5 of the squib housing 4 installed inside the housing plate 3 is ignited by receiving an electrical signal.

이때 스퀴브(5)의 폭발력으로 노치부가 파괴되어 인플레터(1)의 프레셔용기(2)에 충진된 압축가스가 빠져너와 백을 팽창시킨다.At this time, the notch part is destroyed by the explosive force of the squib 5, and the compressed gas filled in the pressure vessel 2 of the inflator 1 escapes and expands the bag.

상기와 같이 압축가스를 저장하는 프레셔용기(2)를 얇은 알루미늄라이너(7)위에 FRP(8)를 팔리민트와인딩하므로서 경량화의 인플레터 제작이 가능하며, 폭음에의한 충격 등을 감소시키게 되는 것이다.As described above, the pressure vessel 2 storing the compressed gas may be manufactured in a lighter inflator by winding the FRP 8 on the thin aluminum liner 7, and the impact caused by the explosion is reduced. .

이상 설명한 바와 같이 프레셔용기를 알루미늄라이너와 FRP로 제작하여 압축가스를 사용하므로서 소음 및 열의 발생이 없어 화상이나 폭음에 의한 손상이 전혀 없게 될 뿐만아니라, 경량화 인플레터 제작이 가능하며, 고압충진을 가능하게 할 수 있는 매우 유용한 고안이다.As described above, the pressure vessel is made of aluminum liner and FRP to use compressed gas, so there is no noise and heat generation, so there is no damage caused by burns or explosions, and it is possible to manufacture a lighter inflator and to charge at high pressure. It is a very useful design that can be done.
