커튼에어백 {CURTAIN AIRBAG}Curtain airbag {CURTAIN AIRBAG}

본 발명은 탑승자 전방에어백과 커튼에어백의 사이로 머리가 이탈되는 현상을 방지할 수 있는 커튼에어백에 관한 것이다.
The present invention relates to a curtain airbag capable of preventing head detachment between a passenger front airbag and a curtain airbag.

차량의 에어백은 전방에어백과 커튼에어백을 들 수 있다. 전방에어백은 스티어링휠 또는 크래쉬패드에 설치되어 탑승자의 전방을 보호하는 것이고, 커튼에어백의 경우 루프측면에 설치되어 하방으로 전개됨으로써 탑승자의 측면을 보호하는 것이다.The airbags of a vehicle include a front airbag and a curtain airbag. The front airbag is provided on the steering wheel or the crash pad to protect the front of the occupant. In the case of the curtain airbag, the front airbag is installed on the side of the roof and is deployed downward to protect the occupant's side.

그러나 이러한 커튼에어백의 존재로 인하여 차량의 옵셋충돌시에는 탑승자의 머리가 전방에어백과 커튼에어백의 사이로 들어가 다치는 경우가 발생하는바, 이러한 현상은 옵셋충돌시험에서도 확인될 수 있다.
However, due to the existence of such a curtain airbag, when the offset collision of the vehicle occurs, the occupant's head may get caught between the front airbag and the curtain airbag, and this phenomenon may be confirmed in the offset collision test.

종래의 KR10-2012-0079695 A "커튼 에어백 장치"는 "인플레이터에서 발생한 가스에 의해 팽창하는 쿠션과; 상기 쿠션의 내부에 배치되고 가스를 상기 쿠션의 내부로 공급하는 내부포켓을 포함하고, 상기 쿠션에는 상기 쿠션의 길이방향으로 팽행한 복수의 수평챔버부가 형성되고, 상기 내부포켓에는 상기 수평챔버부에 상기 가스를 공급하기 위해 상기 수평챔버부에 대응하는 복수의 토출홀이 형성되는 커튼 에어백 장치"를 제시하였다. 그러나 이러한 커튼에어백의 기술에도 불구하고 탑승자의 머리가 커튼에어백과 전방에어백의 사이로 들어가는 현상을 방지할 수는 없었다.
Conventional KR 10-2012-0079695 A "curtain airbag device" includes a "cushion that is inflated by a gas generated in an inflator, an inner pocket disposed inside the cushion and supplying gas to the interior of the cushion, And a plurality of discharge holes corresponding to the horizontal chamber portion for supplying the gas to the horizontal chamber portion are formed in the inner pocket. The curtain airbag device " Respectively. However, despite the technology of the curtain airbag, it was not possible to prevent the occupant's head from entering between the curtain airbag and the front airbag.

상기의 배경기술로서 설명된 사항들은 본 발명의 배경에 대한 이해 증진을 위한 것일 뿐, 이 기술분야에서 통상의 지식을 가진자에게 이미 알려진 종래기술에 해당함을 인정하는 것으로 받아들여져서는 안 될 것이다.

Fig. 2 is a view showing a manufacturing process of the curtain airbag shown in Fig. 1. Fig.
Figs. 3 to 4 are views showing a process of manufacturing a curtain airbag according to still another embodiment of the present invention. Fig.

이하에서는 첨부된 도면을 참조하여 본 발명의 바람직한 실시 예에 따른 커튼에어백에 대하여 살펴본다.Hereinafter, a curtain airbag according to a preferred embodiment of the present invention will be described with reference to the accompanying drawings.

도 1은 본 발명의 일 실시예에 따른 커튼에어백이 전개된 상태를 나타낸 도면이고, 도 2는 도 1에 도시된 커튼에어백의 제작과정을 나타낸 도면이며, 도 3 내지 4는 본 발명의 또 다른 실시예의 커튼에어백의 제작과정을 나타낸 도면이다.FIG. 1 is a view showing a state in which a curtain airbag according to an embodiment of the present invention is developed, FIG. 2 is a view showing a manufacturing process of the curtain airbag shown in FIG. 1, 1 is a view showing a manufacturing process of a curtain airbag of an embodiment.

본 발명의 커튼에어백은, 메인챔버(100)와 메인챔버(100)에서 연장된 보조챔버(200)로 구성되고, 보조챔버(200)는 메인챔버(100)와 연통된 상태에서 메인챔버(100)측으로 접힌 후 단부(240)가 메인챔버(100)에 고정된다.The curtain airbag according to the present invention comprises a main chamber 100 and an auxiliary chamber 200 extending from the main chamber 100. The auxiliary chamber 200 communicates with the main chamber 100 And then the end portion 240 is fixed to the main chamber 100.

즉, 본 발명의 커튼에어백은 메인챔버(100)의 전단부에서 보조챔버(200)만큼 더 연장하여 형성하고, 이를 메인챔버(100)로 접어 결합함으로써 보조챔버(200)에 의해 메인챔버(100)의 전단부가 더 폭이 두꺼워지도록 하는 것이다.That is, the curtain airbag according to the present invention is extended from the front end of the main chamber 100 by as much as the auxiliary chamber 200 and is folded into the main chamber 100 to be connected to the main chamber 100 So that the front end portion of the front end portion becomes thicker.

그리고, 이러한 구성을 통해 탑승자의 전방에어백과 커튼에어백의 사이의 공간을 메우도록 하는 것이다.In this way, the space between the front airbag of the occupant and the curtain airbag is filled up.

이러한 구성은 쉽게 보면, 메인챔버(100)의 전방의 폭을 더 두껍게 설계하는 것으로도 대체할 수 있을 것이나, 메인챔버(100)의 폭을 두껍게 설계할 경우에는 에어백 전방부의 전개성이 떨어지고 더 많은 가스도 요구된다.Such a configuration may be replaced with a design of a larger width in front of the main chamber 100. However, when the width of the main chamber 100 is designed to be large, the frontability of the airbag 100 is poor, Gas is also required.

따라서, 에어백의 메인챔버(100) 전방부의 폭을 키우는 것보다는 이를 더 길게 한 후 전어서 폭을 키우는 것이 필요 가스의 양도 적고 전개성도 좋은 것이다.
Therefore, rather than increasing the width of the front portion of the main chamber 100 of the airbag, it is preferable to increase the width of the front portion of the airbag and to increase the width thereof.

한편, 상기 보조챔버(200)는 전개시 탑승자 전방에어백(10)과 메인챔버(100)의 사이에 위치될 수 있도록 한다. 따라서, 메인챔버(100)의 전방으로 길게 한 후 접어서 보조챔버(200)를 형성할 경우에는 본래의 메인챔버(100)가 위치되어야 하는 전방에어백(10)의 측부까지는 연장하고, 해당 지점에서 더 연장하여 접음으로써 전방에어백(10)의 측부와 보조챔버(200) 및 메인챔버(100)가 측방으로 나란히 위치될 수 있도록 해야 한다.Meanwhile, the auxiliary chamber 200 can be positioned between the passenger airbag 10 and the main chamber 100 during deployment. Therefore, when the auxiliary chamber 200 is formed by lengthening the front side of the main chamber 100 and then extending to the front side of the main chamber 100, it extends to the side of the front air bag 10 where the original main chamber 100 is to be positioned, So that the side of the front airbag 10 and the auxiliary chamber 200 and the main chamber 100 can be positioned laterally side by side.

또한, 상기 탑승자 전방에어백(10), 보조챔버(200) 및 메인챔버(100)는 전개시 상호 밀착되도록 형성됨으로써 옵셋 충돌시에도 탑승자의 머리를 완전히 지지하도록 하고, 상기 탑승자 전방에어백(10), 보조챔버(200) 및 메인챔버(100)는 전개시 전방에어백(10)의 측면에 보조챔버(200)와 메인챔버(100)가 중첩적으로 위치되도록 함으로써 최소한의 보조챔버(200) 부피로도 최대의 효과를 낼 수 있도록 한다.
The passenger's front air bag 10, the auxiliary chamber 200 and the main chamber 100 are formed so as to be in close contact with each other when they are deployed, thereby fully supporting the occupant's head in the event of an offset collision, The auxiliary chamber 200 and the main chamber 100 are arranged in such a manner that the auxiliary chamber 200 and the main chamber 100 are positioned at the side of the front air bag 10 at the time of deployment, So that the maximum effect can be obtained.

한편, 도 2는 도 1에 도시된 커튼에어백의 제작과정을 나타낸 도면으로서, 도시된 바와 같이 (a)상태처럼 보조챔버(200)는 메인챔버(100)의 전단에서 연장되고 (b)상태처럼 보조챔버(200)는 후방으로 접혀 메인챔버(100)와 중첩되며 단부(240)가 메인챔버(100)에 고정되도록 할 수 있다.1, the auxiliary chamber 200 extends from the front end of the main chamber 100 as shown in (a), and (b) The auxiliary chamber 200 may be folded rearward to overlap the main chamber 100 and the end portion 240 may be fixed to the main chamber 100. [

또한, 도 3의 경우에는 보조챔버(200)는 메인챔버(100)의 전단부 상단에서 연장되고 보조챔버(200)는 하방으로 접혀 메인챔버(100)와 중첩되며 단부(240)가 메인챔버(100)에 고정되도록 하는 경우이다.3, the auxiliary chamber 200 is extended from the upper end of the front end of the main chamber 100 and the auxiliary chamber 200 is folded downward to be overlapped with the main chamber 100, 100).

그리고 도 4의 경우는 보조챔버(200)는 메인챔버(100)의 전단부 하단에서 연장되고 보조챔버(200)는 상방으로 접혀 메인챔버(100)와 중첩되며 단부(240)가 메인챔버(100)에 고정되도록 하는 경우이다.
4, the auxiliary chamber 200 is extended from the lower end of the front end of the main chamber 100 and the auxiliary chamber 200 is folded upward to overlap the main chamber 100 and the end portion 240 is overlapped with the main chamber 100 As shown in Fig.

한편, 상기 보조챔버(200)와 메인챔버(100)의 사이의 접히는 지점에는 쿠션의 양면을 접합하는 접합선(220)이 형성되고 보조챔버(200)는 접합선(220)을 기준으로 접혀 메인챔버(100)와 중첩되도록 할 수 있다. 즉, 메인챔버(100)와 보조챔버(200)는 접합선(220)으로 구분되고, 이를 기준으로 접어 보조챔버(200)를 중첩시킬 수 있다. 이러한 접합선(220)의 상하로는 일정 간격 공간이 형성되어 가스가 서로 유통할 수 있도록 한다.
A fixing line 220 joining the both sides of the cushion is formed at a folding point between the auxiliary chamber 200 and the main chamber 100 and the auxiliary chamber 200 is folded on the basis of the fixing line 220, 100). That is, the main chamber 100 and the auxiliary chamber 200 are divided into the joining lines 220, and the auxiliary chamber 200 can be folded on the basis of this. Upper and lower spaces of the fixing line 220 are formed at regular intervals to allow gas to flow therethrough.

상술한 바와 같은 구조로 이루어진 커튼에어백에 따르면, 탑승자 전방에어백과 커튼에어백의 사이로 머리가 이탈되는 현상을 방지할 수 있다.
According to the curtain airbag having the above-described structure, it is possible to prevent the head from being separated from the curtain airbag between the occupant front airbag and the curtain airbag.
