본 고안은 차량의 크래쉬패드(CRASH PAD) 상단에 설치되는 승객보호용 에어백에 관한 것으로서, 보다 상세하게는 하우징의 상면에 끼움홀과 걸림편이 형성되고 에어백 도어측 상부의 연장편에 결합홀이 서로 결합되도록 형성되므로써 하우징과 에어백도어의 조립성이개선되고 조립공정수가 절감되며 원가 및 중량절감이 이루어 지도록 한 승객용 에어백에 관한 것이다.The present invention relates to a passenger protective airbag installed on the top of the crash pad (CRASH PAD) of the vehicle, more specifically, the fitting hole and the engaging piece is formed on the upper surface of the housing and the coupling hole is coupled to each other in the extension of the upper side of the airbag door The present invention relates to a passenger airbag that is formed to improve the assembly of the housing and the airbag door, reduce the number of assembly processes, and reduce cost and weight.
일반적으로, 차량의 정면 충돌시 승객을 보호할 수 있도록 차량의 크래쉬패드(CRASH PAD) 상단에 승객의 보호수단(패신져 사이드 에어백 : Passenger Side Air Bag)이 절실히 요구되었는바 상기 패신져 사이드 에어백은 충돌시 충돌후 30/1000초이내에 에어백을 전개시켜야 한다.In general, a passenger's protection means (passenger side air bags) are urgently needed on the top of the crash pad (CRASH PAD) of the vehicle to protect the passengers in front of the vehicle. In a collision, the airbag must be deployed within 30/1000 seconds of the collision.
종래의 패신져 사이드 에어백은 제1도에 나타낸 바와 같이 일측면이 개방된 장방형 하우징(10)과, 이 하우징(10)내에 인플레터(12)에 일체화된 에어백(14)과, 상기 하우징(10)의 개방면에 장착되도록 상하부에 연장편(16)(18)이 연장된 만곡형의 에어백도어(20)로 구성되어 있다.상기 하우징(10)의 하단면에는 다수의 관통걸림단편(22)이 형성되어 있고 에어백도어(20)하부의 연장편(18)에는 관통결합단편(22)이 관통되는 결합홀(24)과 에어백(14)의 가스압력에 의해 에어백(14)이 전개되도록 절취라인(26)이 형성되어 있다.The conventional passenger side airbag includes a rectangular housing 10 having one side open as shown in FIG. 1, an airbag 14 integrated into the inflator 12 in the housing 10, and the housing 10. It is composed of a curved airbag door 20, the extension piece 16, 18 is extended to the upper and lower portions so as to be mounted on the open surface. Is formed therein and the extension piece 18 below the airbag door 20 has a cutting line such that the airbag 14 is developed by the gas pressure of the airbag 14 and the coupling hole 24 through which the through coupling piece 22 penetrates. (26) is formed.
상기와 같이 구성된 종래의 승객용 에어백에 있어서는 하우징(10)과 에어백도어(20)가 리벳(28)에 의해 조립되어 있기 때문에 부품수 및 공정이 증가되고 그 구조가 복잡하여 조립불량이 발생되기 쉬운 것이었으며 이에 따라서 원가상승의 요인이되는 것이었다.In the conventional passenger airbag configured as described above, since the housing 10 and the airbag door 20 are assembled by the rivet 28, the number of parts and the process are increased, and the structure thereof is complicated, so that poor assembly is likely to occur. Therefore, it was a factor of cost increase.
본 고안은 상기와 같은 종래의 제반 문제점을 해결하기 위해 연구개발한 것으로서, 본 고안의 목적은 하우징의 상면에 끼움홀과 걸림편이 형성되고 에어백도어측 상부의 연장편에 결합홀이 서로결합되도록 형성됨으로써 하우징과 에어백도어의 조립성이 개선되고 조립공정 및 부품수가 절감됨은 물론 원가 및 중량절감이 이루어 지도록 한 승객용 에어백을 제공하는데 있다.The present invention has been researched and developed in order to solve the conventional problems as described above, the object of the present invention is to form a fitting hole and the engaging piece on the upper surface of the housing and the coupling hole is formed to be coupled to each other in the extension of the upper side of the airbag door As a result, the assembly of the housing and the airbag door is improved, the assembly process and the number of parts are reduced, as well as the cost and weight of the passenger.
상기와 같은 목적을 달성하기 위한 본 고안의 특징은, 일측면이 개방된 하우징과, 이 하우징내에서 인플레터에 일체화된 에어백과, 상기 하우징의 개방면에 장착되도록 상하부에 연장편이 연장된 만곡형의 에어백도어로 구성된 승객용 에어백에 있어서, 상기 하우징 상면에는 선단에 걸림편을 갖도록 연장편의 두께만큼 성형된 끼움홀이 형성되고 상기 에어백도어 상부의 연장편에 상기 끼움홀의 걸림편에 걸리도록 결합홀이 형성되어 있는 점이 있다.Features of the present invention for achieving the above object, the housing is open on one side, the airbag integrated in the inflate in the housing, the curved type extending the upper and lower parts to be mounted on the open surface of the housing In the passenger airbag consisting of the airbag door of the, the upper surface of the housing is formed with a fitting hole shaped to the thickness of the extension piece to have a locking piece on the front end and the engaging hole to be caught by the locking piece of the fitting hole on the extension of the upper portion of the airbag door This is formed.
이하, 본 고안에 따른 승객용 에어백을 바람직한 일 실시예의 첨부도면을 참조하여 상세히 설명한다.Hereinafter, a passenger airbag according to the present invention will be described in detail with reference to the accompanying drawings of a preferred embodiment.
제2도 및 제3도는 본 고안에 따른 승객용 에어백을 설명하기 위해 나타낸 도면이다.2 and 3 are views for explaining the passenger airbag according to the present invention.
여기에서, 일측면이 개방된 장방형의 하우징(10)이 형성되고 상기 하우징(10)내에 인플레터(12)에 일체화된 에어백(14)이 내장되어 있으며, 상기 하우징(10)의 개방면에 장착되도록 연장편(16)(18)이 형성된 만곡형의 에어백도어(20)가 장착되어 있다.Here, a rectangular housing 10 having one side open is formed, and an air bag 14 integrated into the inflator 12 is built in the housing 10, and is mounted on an open surface of the housing 10. The curved airbag door 20 in which the extension pieces 16 and 18 were formed is attached.
상기 하우징(10)의 상면에는 양측에 걸림편(30)을 갖도록 연장편(16)의 두께만큼 하부로 성형된 끼움홀(32)이 형성되어 있고 그 하단면에는 다수의 관통결합단편(22)이 형성되어 있으며, 상기 에어백도어(20) 상하부의 연장편(16)(18)에는 하우징(10)측 끼움홀(32)선단의 걸림편(30)과 관통결합단편(22)에 상응하여 끼워맞춤되도록 다수의 결합홀(34)(24)이 형성되어 있다The upper surface of the housing 10 is formed with a fitting hole 32 formed downward by the thickness of the extension piece 16 to have a locking piece 30 on both sides and a plurality of through coupling end pieces 22 on the bottom surface thereof. Is formed, and fitted to the extension piece (16, 18) of the upper and lower portions of the air bag door 20 corresponding to the engaging piece 30 and the through-coupled end piece 22 of the tip of the housing 10 side fitting hole (32). A plurality of coupling holes 34 and 24 are formed to fit.
상기 에어백도어(20)하부의 연장편(18)에는 에어백(14)의 가스압력에 의해 에어백(14)이 전개되도록 절취라인(26)이 형성되어 있다.An extension piece 18 under the airbag door 20 has a cutting line 26 formed therein so that the airbag 14 is deployed by the gas pressure of the airbag 14.
상기와 같이 구성된 승객용 에어백은 제2도 및 제3도와 같이 에어백도어(20)측 연장편(16)을 하우징(10)의 끼움홀(32)에 삽입하여 끼우면 연장편(16)의 결합홀(34)에 하우징(10)측 끼움홀(32)선단의 걸림편(30)이 걸리므로 하우징(10)과 에어백도어(20)가 서로 결합되게 된다.The passenger airbag configured as described above has the coupling hole of the extension piece 16 when the extension piece 16 of the airbag door 20 side is inserted into the fitting hole 32 of the housing 10 as shown in FIGS. 2 and 3. Since the locking piece 30 at the tip of the housing 10 side fitting hole 32 is caught by the 34, the housing 10 and the airbag door 20 are coupled to each other.
이러한 상태에서 하우징(10)의 관통결합단편(22)을 에어백도어(20)측 연장편(18)의 결합홀(24)에 끼워맞춘 후 차량의 도어에 설치하여 사용한다.In such a state, the through coupling piece 22 of the housing 10 is fitted to the coupling hole 24 of the extension piece 18 on the airbag door 20 side, and then installed on the door of the vehicle.
상기와 같이 조립되어진 승객용 에어백은 전방 혹은 경사충돌시 차량의 감속도를 프론트패널(FRONT TUNNEL)에 장착된(도시되지 않음)가속도계가 감지하여 전개조건시 밧데리의 전원이 인플레터(12)에 인가하게 된다.The passenger airbag assembled as described above detects the deceleration of the vehicle in the front or incline collision (not shown) by the accelerometer mounted on the front panel (FRONT TUNNEL), and the battery power is supplied to the inflator 12 in the deployment condition. Will be authorized.
이때, 상기 인플레터(12)가 점화됨에 따라 순간적으로 부풀어 올라 에어백(14)이 전개되려는 에어백(14)내의 가스압력에 의해서 에어백도어(20)측 연장편(18)의 절취라인(26)이 절취되면서 에어백도어(20)가 제2도의 가상선과 같이 개방됨과 동시에 에어백(14)이 차량의 내부로 전개되는 것이다.At this time, as the inflator 12 is ignited, the cutting line 26 of the extension piece 18 of the airbag door 20 side is cut by the gas pressure in the airbag 14 to be inflated instantaneously. As the airbag door 20 is cut off, the airbag door 20 is opened as shown in FIG. 2 and the airbag 14 is deployed inside the vehicle.
그러므로, 상기와 같은 본 고안에 다른 승객용 에어백은 걸림편(30)을 갖는 하우징(10)의 끼움홀(32)과 에어백도어(20)의 결합홀(34)에 의해 간단하게 서로 결합고정됨으로써 하우징(10)과 에어백도어(20)의 조립성이 개선되고 조립공정 및 부품수가 절감됨은 물론 원가 및 중량절감이 이루어 지는 것이다.Therefore, the passenger airbag according to the present invention as described above is simply fixed to each other by the fitting hole 32 of the housing 10 having the locking piece 30 and the coupling hole 34 of the airbag door 20. The assembly of the housing 10 and the airbag door 20 is improved, and the assembly process and the number of parts are reduced, as well as cost and weight.
이상에서와 같이 본 고안에 다른 승객용 에어백에 의하면, 하우징 상면에 끼움홀과 걸림편이 형성되고 에어백도어측 상부의 연장편에 결합홀이 서로 결합되도록 형성됨으로써 하우징과 에어백도어의 조립성이 개선되고 조립공정수가 절감됨은 물론 원가 및 중량절감이 이루어 지는 효과가 있다.According to the passenger airbag according to the present invention as described above, the fitting hole and the engaging piece is formed on the upper surface of the housing and the coupling hole is formed to be coupled to each other on the extension of the upper portion of the airbag door side to improve the assembly of the housing and the airbag door The assembly process is reduced, as well as cost and weight can be reduced.
