Description

승객보호용 에어백Passenger Protective Air Bag

본 발명은 승객보호용 에어백에 관한 것으로서, 보다 상세하게는 쿠션백의 내부압력에 따라 사이즈가 가변되도록 이중의 내/외부 쿠션백으로 구성되어져 있는 승객보호용 에어백에 관한 것이다.The present invention relates to a passenger protection airbag, and more particularly to a passenger protection airbag consisting of a double inner / outer cushion bag to vary in size depending on the internal pressure of the cushion bag.

일반적으로, 에어백(Air Bag)은 차량의 충돌시 승객을 보호할 수 있도록 차량의 크래쉬 패드나 도어 등에 설치되어진다.In general, an air bag is installed in a crash pad or a door of a vehicle so as to protect a passenger in a crash of the vehicle.

이러한 기술과 관련된 종래의 전형적인 승객보호용 에어백에 대하여 참고적으로 도 1 및 도 2에 나타내었다.A typical passenger protective airbag associated with this technique is shown in FIGS. 1 and 2 for reference.

에어백은 카울 크로스 멤버(10)와 크래쉬 패드(12)의 상부에 복수의 체결부재(14)로 장착되어 있으며, 이는 일측면이 개바된 장방형의 하우징(16)과, 이 하우징(16)내에서 충돌시 점화되어 가스를 발생하는 인플레이터(18)와, 이 인플레이터(18)에 일체화되고 승객의 상체를 향해 전개되도록 형성된 쿠션백(20a)과, 상기 하우징(16)의 개방면에 쿠션백(20a)의 전개시 일측단이 절단되어 개방되도록 장착된 만곡형의 에어백도어(22)로 구성되어 있다.The airbag is mounted on the cowl cross member 10 and the crash pad 12 with a plurality of fastening members 14, which are rectangular housings 16 with one side open and within the housings 16. An inflator 18 that ignites upon collision and generates gas, a cushion bag 20a that is integrated with the inflator 18 and is formed to extend toward the upper body of the passenger, and a cushion bag 20a on the open surface of the housing 16. It is composed of a curved airbag door 22 mounted so that one side end is cut open when it is deployed.

상기와 같이 구성된 종래의 승객보호용 에어백에 있어서는 차량이 충돌되게 되면 점화수단(도시되지 않았음)에 의해 인플레이터(18)가 점화됨에 따라 순간적으로 부풀어 올라 쿠션백(20)이 전개되려는 쿠션백(20)내의 가스압력에 의해서 에어백도어(22)측 절취라인이 끊어지면서 에어백도어(22)가 개방됨과 동시에 도 2와 같이 쿠션백(20)이 승객을 향하여 전개되므로 승객을 보호하게 된다.In the conventional passenger protective airbag configured as described above, when the vehicle collides, the inflator 18 is swelled instantaneously as the inflator 18 is ignited by an ignition means (not shown). The airbag door 22 is opened while the airbag door 22 side cutting line is disconnected by the gas pressure in the c), and the cushion bag 20 is deployed toward the passenger as shown in FIG. 2 to protect the passenger.

그러나, 상기와 같은 종래의 승객보호용 에어백은 차량 충돌시 쿠션백(20)이 일정한 크기로 정하여져 있으므로 쿠션백(20)내의 가스압력이 설계치대로 유지되어야만 에어백도어(22)가 개방되고 이어서 쿠션백(20) 또한 전개되므로 단시간내에 가스가 충진되지 않을 수 있으며, 이와같이 쿠션백(20)내의 압력이 설계치 압력보다 낮으면 충돌시 승객보호를 위한 에어백으로서의 제기능을 기대할 수 없는 문제점이 있었다.However, in the conventional passenger protective airbag as described above, the cushion bag 20 is determined to have a predetermined size during a vehicle collision, so that the airbag door 22 is opened only after the gas pressure in the cushion bag 20 is maintained at a design value. 20) Also, the gas may not be filled in a short time because it is deployed, and if the pressure in the cushion bag 20 is lower than the design value pressure, there is a problem in that it cannot be expected to function as an airbag for passenger protection in the event of a collision.

본 발명의 목적은 상기한 바와같은 종래의 제반 폐단 및 문제점을 해결하기 위해 연구 개발한 것으로서, 내부 쿠션백의 가스압력이 낮으면 소형으로 전개되고 가스압력이 높으면 대형으로 전개되므로 내부 쿠션백의 가스압력에 따라 사이즈가 가변되며, 이로 인하여 상황에 적합한 에어백 형상을 얻을 수 있어 승객 대응성이 향상되도록 한 승객보호용 에어백을 제공하는데 있다.An object of the present invention has been researched and developed in order to solve the conventional closed end and problems as described above, because the gas pressure of the inner cushion bag is developed in a small size and the gas pressure is developed in a large size, so the gas pressure of the inner cushion bag According to the present invention, the size of the vehicle is variable, and thus, an airbag shape suitable for a situation can be obtained, thereby providing a passenger protective airbag for improving passenger responsiveness.

상기와 같은 목적을 구현할 수 있도록 본 발명은 일측면이 개방된 장방형의 하우징과, 이 하우징내에서 충돌시 점화되어 가스를 발생하는 인플레이터와, 이 인플레이터에 일체화되고 승객의 상체를 향해 전개되도록 형성된 쿠션백과, 상기 하우징의 개방면에 쿠션백 전개시 일측단이 절단되어 개방되도록 장착된 만곡형의 에어백 도어를 포함하고 있는 승객보호용 에어백에 있어서, 상기 쿠션백은 가스압력에 따라 가변되는 복수의 벤트홀이 형성되어진 내부 쿠션백과, 이 내부 쿠션백의 압력에 벤트홀이 개방되어 그 외부측으로 충진되도록 씌워져 있는 외부 쿠션백으로 형성됨을 특징으로 한다.In order to achieve the above object, the present invention provides a rectangular housing having one side open, an inflator ignited upon collision with the housing, and a cushion formed to be integrated with the inflator and deployed toward the upper body of the passenger. In the airbag for passenger protection comprising a bag and a curved airbag door is mounted so that one end is cut open when the cushion bag is deployed on the open surface of the housing, the cushion bag is a plurality of vent holes varying according to the gas pressure The inner cushion bag is formed, and the outer cushion bag is covered with a vent hole is opened to the outside of the pressure is filled in the pressure of the inner cushion bag.

이하에서 본 발명에 따른 승객보호용 에어백을 좀더 구체적으로 설명하여 봄으로써 본 발명의 특징들이 쉽게 이해될 것이다.The features of the present invention will be readily understood by describing the airbag for passenger protection according to the present invention in more detail below.

도 3은 본 발명에 따른 승객보호용 에어백이 전개된 상태를 나타낸 단면도이고 도 4는 본 발명에서 가스압력에 따른 쿠션백의 전개상태를 나타낸 단면도이다.Figure 3 is a cross-sectional view showing a state of deployment of the passenger protective airbag according to the present invention and Figure 4 is a cross-sectional view showing the deployment state of the cushion bag according to the gas pressure in the present invention.

도면에 도시한 바와같이, 일측면이 개방된 장방형의 하우징(16)에는 충돌시 점화되어 가스를 발생하는 인플레이터(18)가 설치되어져 있으며, 이 인플레이터(18)에 일체화되어 승객의 상체를 향해 전개되도록 형성된 이중의 쿠션백(20a)이 형성되어져 있다.As shown in the figure, the rectangular housing 16 with one side open is provided with an inflator 18 that ignites upon collision and generates gas. The inflator 18 is integrated with the inflator 18 and extends toward the upper body of the passenger. The double cushion bag 20a is formed so that it may be formed.

또, 상기 하우징(16)의 개방면에 쿠션백(20a)의 전개시 일측단이 절단되어 개방되도록 만곡형의 에어백도어(22)로 장착되어져 있다.In addition, a curved airbag door 22 is mounted on the open surface of the housing 16 so that one end of the cushion bag 20a is cut and opened.

그리고, 상기 쿠션백(20a)은 가스압력에 따라 쿠션백(20a)의 전개 사이즈가 가변되도록 이중으로 형성되어져 있으며, 이는 내부의 가스압력에 따라 개방되는 사이즈가 다르도록 복수의 벤트홀(25)이 형성되어진 내부 쿠션백(23)과, 이 내부 쿠션백(23)의 압력에 벤트홀(25)이 개방되어 그 외부측으로 충진되도록 외부 쿠션백(24)으로 씌워져 있다.In addition, the cushion bag 20a is formed in a double so that the deployment size of the cushion bag 20a is variable according to the gas pressure, which is a plurality of vent holes 25 so that the size of the cushion bag 20a is different according to the gas pressure therein. The inner cushion bag 23 formed therein and the outer cushion bag 24 are covered with a vent hole 25 to be opened and filled to the outside thereof by the pressure of the inner cushion bag 23.

상기와 같이 구성된 본 발명에 따른 승객보호용 에어백은 종래와 마찬가지로 차량이 충돌되게 되면 점화수단(도시되지 않았음)에 의해 인플레이터(18)가 점화됨에 따라 순간적으로 부풀어 올라 쿠션백(20a)이 전개되려는 쿠션백(20a)내의 가스압력에 의해서 에어백도어(22)측 절취라인이 끊어지면서 에어백도어(22)가 개방됨과 동시에 쿠션백(20)이 승객을 향하여 전개되므로 승객을 보호하게 된다.The passenger protection airbag according to the present invention configured as described above is inflated instantaneously as the inflator 18 is ignited by an ignition means (not shown) when the vehicle collides as in the prior art, and thus the cushion bag 20a is to be deployed. As the cutting line of the airbag door 22 is cut off by the gas pressure in the cushion bag 20a, the airbag door 22 is opened and the cushion bag 20 is deployed toward the passenger, thereby protecting the passenger.

이때, 쿠션백(20a)은 도 3에 나타낸 바와 같이 가스압력에 따라 쿠션백(20a)의 사이즈가 가변적으로 전개된다.At this time, as shown in Fig. 3, the cushion bag 20a is variably developed in size in accordance with the gas pressure.

좀더 구체적으로 설명하면, 가스발생이 적어 가스압력이 낮으면 내부 쿠션백(23)의 벤트홀(25)이 개방되지 않아 도 3a와 같이 내부 쿠션백(23)의 사이즈로 전개되고, 가스압력이 설계치 압력보다 약간 낮으면 내부 쿠션백(23)의 벤트홀(25)이 미약하게 일부반 개방되므로 도 3b와 같이 내부 쿠션백(23) 외측의 외부 쿠션백(24)에도 약간의 가스가 충진상태로 전개된다.More specifically, if the gas pressure is low because the gas generation is low, the vent hole 25 of the inner cushion bag 23 is not opened, and as shown in FIG. 3A, the size of the inner cushion bag 23 is developed. When the pressure is slightly lower than the designed value, the vent hole 25 of the inner cushion bag 23 is slightly half-opened, so that some gas is filled in the outer cushion bag 24 outside the inner cushion bag 23 as shown in FIG. 3B. Is developed.

또, 가스압력이 설계치대로 높은 가스압력이면 내부 쿠션백(23)의 벤트홀(25)이 충분히 개방되므로 도 3c와 같이 내/외부 쿠션백(21,22)이 모두 최대로 전개되게 된다.In addition, if the gas pressure is a high gas pressure as designed, the vent hole 25 of the inner cushion bag 23 is sufficiently opened, so that the inner and outer cushion bags 21 and 22 are fully developed as shown in FIG. 3C.

따라서, 인플레이터(18)에서 발생되는 가스압력에 따라 적합한 사이즈의 내/외부 쿠션백(20a)이 전개되므로 상황에 적합한 에어백 형상을 얻을 수 있으며, 결과적으로 승객 대응성이 향상되는 것이다.Therefore, since the inner / outer cushion bag 20a of a suitable size is developed according to the gas pressure generated in the inflator 18, an airbag shape suitable for a situation can be obtained, and as a result, passenger responsiveness is improved.

이상에서 상세하게 설명한 바와 같이 본 발명에 다른 승객보호용 에어백은 인플레이터로부터 발생되는 가스압력이 낮으면 내부 쿠션백 사이즈의 소형으로 전개되고 그 가스압력이 높으면 외부 쿠션백 사이즈의 대형으로 전개되므로 내부 쿠션백의 가스압력에 따라 사이즈가 가변되는 특유의 효과가 있다.As described in detail above, the passenger protective airbag according to the present invention has a small inner size of the inner cushion bag when the gas pressure generated from the inflator is low, and a large inner size of the outer cushion bag size when the gas pressure is high. There is a unique effect that the size is variable according to the gas pressure.

또한, 인플레이터로부터 발생되는 가스압력에 따라 쿠션백의 사이즈가 가변되므로 상황에 적합한 에어백 형상을 얻을 수 있고, 이로 인하여 승객 대응성이 향상되는 특유의 효과가 있다.In addition, since the size of the cushion bag is variable according to the gas pressure generated from the inflator, it is possible to obtain an airbag shape suitable for a situation, thereby improving the passenger responsiveness.

끝으로, 본 발명은 특정한 일 실시예에 관련하여 도시하고 설명하였지만 이하의 특허청구의 범위에 의해 마련되는 본 발명의 정신이나 분야를 이탈하지 않는 한도내에서 다양하게 개조 및 변화시켜도 본 발명의 기술범주에 속함을 밝혀두고자 한다.Finally, although the present invention has been shown and described with respect to one particular embodiment, various modifications and changes can be made without departing from the spirit or field of the invention as set forth in the following claims. I want to make sure that it belongs to the category.
