Description
본 발명은 자동차의 에어백 도어에 관한 것으로, 특히 제작이 용이할 뿐만 아니라 에어백 전개가 균형있게 이루어지도록 된 자동차의 에어백 도어에 관한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an airbag door of a motor vehicle, and more particularly to an airbag door of a motor vehicle that is not only easy to manufacture but also has a balanced airbag deployment.
주지된 바와 같이 에어백 시스템은 스티어링휠과 조수석 앞쪽의 크래쉬 패드에 에어백 모듈을 장착하고, 충돌을 감지한 센서가 상기 에어백 모듈 내의 인플레이터를 착화시켜 순간적으로 에어백이 전개되도록 된 것으로서, 운전자나 조수석 승차자의 상해정도를 경감시키기 위해 설치한다.As is well known, the airbag system is equipped with an airbag module on a crash pad in front of the steering wheel and the front passenger seat, and a sensor that detects a collision ignites the inflator in the airbag module so that the airbag is instantaneously deployed. Install to reduce the degree of injury.
한편, 조수석 승차자용 에어백 모듈의 장착상태는 도 1에 도시된 바와 같은바, 에어백 도어(20)가 크래쉬패드(10)의 표면과 동일면을 이루도록 에어백 모듈은 크래쉬패드(10)의 안쪽으로 내장·설치된다.Meanwhile, as shown in FIG. 1, the airbag module is built into the crash pad 10 so that the airbag door 20 forms the same surface as the surface of the crash pad 10. Is installed.
상기 에어백 도어(20)의 단면은 도 2에 도시된 바와 같은데, 힌지고정된 상부를 제외한 좌우 및 아래쪽 부분에 연이어진 장착단(21)이 형성되되, 이 장착단(21)은 에어백 도어(20) 하면에 수직으로 형성된 수직리브(21a)와, 이 수직리브(21a)가 직각으로 외향절곡되어 형성된 수평플랜지(21b)로 이루어지며, 이 수평플랜지(21b)가 크래쉬패드 코어(11)에 부착됨으로써 고정된다.The cross-section of the airbag door 20 is as shown in Figure 2, the mounting end 21 is formed in the left and right and the lower portion except the hinged top is formed, the mounting end 21 is the airbag door 20 A vertical flange 21a formed perpendicular to the bottom surface and a horizontal flange 21b formed by bending the vertical ribs 21a outward at right angles are attached to the crash pad core 11. It is fixed.
한편, 상기 수직리브(21a)에는 테어라인(tear line ; 22)이 형성되어 있어, 에어백 전개시 에어백의 전개력에 의해 이 테어라인(22)이 찢어지면서 에어백 도어(20)가 개방되도록 되어 있다.On the other hand, a tear line 22 is formed in the vertical rib 21a, and the air bag door 20 is opened while the tear line 22 is torn due to the force of the air bag when the air bag is deployed.
그런데, 에어백 도어(20)의 두께가 2.5∼4 mm 인데 반하여 상기 테어라인(22)의 두께는 0.2∼0.3 mm 의 매우 얇은 두께로 성형됨에 따라, 가공이 난해하여 불량률이 높은 문제점이 있었다.By the way, the thickness of the air bag door 20 is 2.5 to 4 mm, whereas the thickness of the tear line 22 is molded into a very thin thickness of 0.2 to 0.3 mm, there is a problem that processing is difficult and high defect rate.
또한, 부풀려지는 에어백의 전개력에 의해 상기 테어라인(22)이 찢겨질 때 최초로 찢어지는 위치가 일정하지 않고, 이에 따라 찢겨지는 상태도 일정하지 않으므로 에어백의 전개가 일정하고 안정감 있게 이루어지지 못할 뿐만 아니라, 이에따라 승차자를 보호하는 성능도 저하되는 문제점이 있었다.In addition, when the tear line 22 is torn by the inflating force of the inflating airbag, the first tearing position is not constant, and thus the tearing state is not constant. Therefore, the deployment of the airbag is not uniform and stable. Accordingly, there is a problem that the performance of protecting the occupant is also reduced.
이에 본 발명은 상기와 같은 문제점을 해결하기 위하여 발명된 것으로, 에어백 도어 가공이 용이하고, 또한 에어백 도어의 개방이 일정하고 안정적으로 이루어짐으로써 에어백이 보다 신속하고 안정적으로 전개되어 승차자 보호성능이 향상될 수 있도록 된 자동차의 에어백 도어를 제공함에 그 목적이 있다.Accordingly, the present invention has been invented to solve the above problems, the airbag door processing is easy, and the airbag door is opened and made stable and stable, the airbag is deployed more quickly and stably to improve the occupant protection performance It is an object of the present invention to provide an airbag door of a vehicle which is made possible.

상기와 같은 목적을 달성하기 위한 본 발명 에어백 도어는 하면의 양측부 및 하부에 연이어진 장착단이 형성되되, 이 장착단의 단부에는 원형단면을 가지는 삽입부가 형성되는 구조로 이루어지며, 이 삽입부는 크래쉬패드 코어에 형성된 수용부에 끼워지게 된다.Air bag door of the present invention for achieving the above object is formed with a mounting end connected to both sides and the lower portion of the lower surface, the end of the mounting end is made of a structure that is formed with an insert having a circular cross-section, the insertion portion It is fitted to the receiving portion formed in the crash pad core.
따라서, 가공이 용이할 뿐만 아니라, 개방이 용이하여 에어백의 전개가 균형있고 안정적으로 이루어질 수 있게 된다.Therefore, not only the processing is easy, but also the opening is easy, so that the deployment of the airbag can be made in a balanced and stable manner.
이하, 본 발명을 첨부된 예시도면을 참조하여 상세히 설명한다.Hereinafter, with reference to the accompanying drawings, the present invention will be described in detail.
도 3은 본 발명에 따른 에어백 도어의 단면도로서, 평판형 에어백 도어(20)의 하면에는 양측부와 하부에 연이어진 장착단(21)이 형성되되, 이 장착단(21)의 단부는 원형단면 형상의 삽입부(21c)가 형성된다.Figure 3 is a cross-sectional view of the airbag door according to the present invention, the lower end of the flat type airbag door 20 is formed with a mounting end 21 connected to both sides and the bottom, the end of the mounting end 21 is a circular cross section The insertion part 21c of a shape is formed.
한편, 에어백 도어(20)가 장착되는 크래쉬패드 코어(11)에는 상기 삽입부(21c)가 끼워지는 수용부(12)가 형성되어 있어서, 이 수용부(12)에 삽입부(21c)가 끼워짐으로써 에어백 도어(20)가 크래쉬패드 코어(11)에 고정된다.On the other hand, the crash pad core 11 to which the airbag door 20 is mounted is formed with a receiving portion 12 into which the inserting portion 21c is fitted, so that the inserting portion 21c is inserted into the receiving portion 12. The airbag door 20 is fixed to the crash pad core 11 by being loaded.
또한, 상기 수용부(12)의 상부 양단은 외측으로 절곡성형된 절곡단(12a)으로 형성되어 있어서, 삽입부(21c)가 삽입되기 용이하도록 되어 있다.In addition, the upper both ends of the receiving portion 12 is formed by the bent end (12a) bent outward, the insertion portion (21c) is easy to insert.
이와 같은 상태로 닫혀 있는 상기 에어백 도어(20)는 에어백의 전개력에 의해 개방될 때 종래와 같이 몸체의 일부가 찢어지면서 열려지는 것이 아니라, 단순 결합되어 있는 삽입부(21)와 수용부(12)가 분리되면서 열려지는 것이기 때문에 개방이 매우 신속하고 일정하게 이루어진다.The airbag door 20, which is closed in such a state, is not opened when a part of the body is torn as in the prior art when opened by the force of deployment of the airbag, but the insertion part 21 and the receiving part 12 are simply coupled. Is opened in isolation, so the opening is very quick and constant.
따라서, 에어백 도어(20)를 밀고 나오는 에어백의 전개 상태 또한 매우 균형있고 안정된 상태로 전체적으로 고르게 부풀게 되며, 이에 의해 승차자의 상체를 받쳐 줄 수 있는 상태가 보다 신속하고 양호한 상태로 준비되어짐으로써 승차자를 보다 효과적으로 보호할 수 있게 된다.Therefore, the airbag deployment state of the airbag pushing out the airbag door 20 is also inflated evenly in a very balanced and stable state as a whole, whereby a state capable of supporting the upper body of the rider is prepared in a faster and better state so that the rider It can effectively protect.
또한, 상기 삽입부(21c)와 수용부(12)는 종래 테어라인에 비하여 매우 두꺼운 두께로 성형되고, 그 형상 또한 복잡한 것이 아니므로 제작이 용이하고, 불량품도 많이 나오지 않게 된다.In addition, the inserting portion 21c and the receiving portion 12 are molded to a very thick thickness as compared to the conventional tear line, the shape is also not complicated, it is easy to manufacture, and not much defective products.
또한, 조립시 종래에는 장착단(21)의 수평플랜지(21b)에 접착재를 바르고, 크래쉬패드 코어(11)에 부착하여야만 했으므로 번거롭고 시간이 오래 걸렸으나, 본 발명에서는 단순히 에어백 도어(20)를 닫고 눌러주면 삽입부(21c)가 수용부(12)에 끼워지면서 고정되므로 작업이 단순용이하고 시간도 적게 걸리게 된다.In addition, when assembling, in the past, the adhesive was applied to the horizontal flange 21b of the mounting end 21 and attached to the crash pad core 11, which was cumbersome and time-consuming, but in the present invention, the airbag door 20 was simply closed. When pressed, the insertion portion 21c is fixed while being inserted into the accommodation portion 12, so that the operation is simple and takes less time.
이상 설명한 바와 같이 본 발명에 따르면, 에어백 도어가 테어라인이 찢기면서 개방되지 않고 삽입부와 수용부가 분리되면서 개방되므로 개방이 부드러우면서도 신속하게 이루어지고, 이에 따라 에어백 도어가 에어백의 전개에 미치는 영향이 최소화됨으로써 에어백이 일정하게 균형잡힌 상태로 신속하게 전개됨으로써 승차자 보호성능이 향상되며, 또한 테어라인 가공이 필요 없게 되므로 가공이 용이하고 불량률이 감소되며, 장착도 수월할 뿐만 아니라 시간도 적게 걸리게 되는 효과가 있다.As described above, according to the present invention, since the airbag door is not opened due to tearing of the tear line but is opened by separating the insertion part and the receiving part, the opening is made smoothly and quickly, and thus the influence of the airbag door on the deployment of the airbag. By minimizing the airbags, the airbags can be deployed in a constant and balanced state, improving the occupant protection performance and eliminating the need for tear line machining, which makes processing easier, reduces the defective rate, facilitates installation, and takes less time. It works.
