이하, 첨부한 도면에 의거하여 본 발명의 구성에 대하여 상세히 설명한다.EMBODIMENT OF THE INVENTION Hereinafter, the structure of this invention is demonstrated in detail based on an accompanying drawing.
도 3은 본 발명에 따른 내압조절수단을 갖는 에어백의 구성 상태를 보인 도면이고, 도 4는 본 발명에 따른 내압조절수단을 갖는 에어백의 사용상태를 보인 도면이다.Figure 3 is a view showing the configuration of the airbag having a pressure-resistant control means according to the invention, Figure 4 is a view showing a state of use of the airbag having a pressure-resistant control means according to the invention.
본 발명의 구성을 살펴 보면, 측면부분에 내부의 가스를 외부로 일정량 배출하여 내압을 조절하도록 하는 가스배출공(15)을 갖는 에어백(10)에서, 상기 가스배출공(15)의 주변에 내압의 크기에 따라 절개되도록 형성된 절개부(20)와, 상기 절개부(20)의 절개 상태의 진행을 정지시키도록 절개부(20)의 끝단부에 원형으로 형성된 절개차단공(25)으로 구성된다.Looking at the configuration of the present invention, in the airbag 10 having a gas discharge hole 15 to control the internal pressure by discharging a predetermined amount of the gas inside to the outside, the internal pressure around the gas discharge hole 15 It is composed of a cutout portion 20 formed to be cut according to the size of the cutout hole 25 formed in a circular shape at the end of the cutout portion 20 to stop the progress of the cut state of the cutout portion 20 .
그리고, 상기 절개부(20)는 일정한 압력이상에서 절개부(20)가 벌려지도록 구성된 것으로서, 가스배출공(15)으로 배출되는 가스의 량이 충분하지 못하여 에어백(10)의 내압이 탑승객(30)에게 반발력을 심하게 가할 정도로 지나치게 큰 경우 가스배출량을 늘려주기 위하여 절개부(20)가 일정량 절개되어지도록 구성된다.In addition, the cutout 20 is configured to open the cutout 20 at a predetermined pressure or more, and the amount of gas discharged to the gas discharge hole 15 is not sufficient, so that the internal pressure of the airbag 10 may be increased. If too large enough to apply a strong repulsive force to the incision is configured to be cut a certain amount in order to increase the amount of gas discharged.
한편, 본 발명의 절개차단공(25)에 절개부(20)를 형성하는 방법을 살펴보면, 절개차단공(25)의 주위에 레이저 커팅방법(Laser Cutting Method)으로 두께에 대하여 일정한 깊이로 절개부(20)를 미리 절개시킨 상태로 두어서 절개차단공(25)에 강한 압력이 가하여지는 경우 전단력이 약한 절개부(20)가 먼저 절개되도록 구성한다.On the other hand, looking at the method of forming the incision 20 in the incision blocking hole 25 of the present invention, the incision to a certain depth with respect to the thickness with a laser cutting method (Laser Cutting Method) around the incision blocking hole 25 Leave (20) in a state in which the incision in advance when a strong pressure is applied to the incision blocking hole 25 is configured so that the incision 20 is weak shear force first.
이하, 본 발명의 작용을 상세하게 살펴보도록 한다.Hereinafter, the operation of the present invention will be described in detail.
먼저, 본 발명의 사용 상태를 살펴보게 되면, 본 발명에 따른 에어백(10)을 인스트루먼트패널의 적절한 위치에 설치하여 자동차를 운행하다가 정면충돌사고가 발생하는 경우 충돌 상태를 미도시된 센서에서 감지하여 화약을 폭발시켜 가스를 발생하게 된다.First, looking at the state of use of the present invention, while installing the airbag 10 according to the present invention in an appropriate position of the instrument panel to drive the car while the front collision accident occurs by detecting the collision state in the sensor not shown Explosives explode to produce gas.
그리고, 화약의 폭발에 의하여 가스가 발생되어 도 4에 도시된 바와 같이, 에어백(10)의 내부로 가스가 급속하게 유입되어 팽창되어진다. 이와 동시에 탑승객(30)의 몸은 전방으로 쏠리면서 에어백(30)과 접촉되어지면서 완충작용에 의하여 신체의 손상을 방지하게 된다.In addition, the gas is generated by the explosion of the explosive, and as shown in FIG. 4, the gas is rapidly introduced into the airbag 10 and expanded. At the same time, the body of the passenger 30 is in contact with the air bag 30 while being moved forward to prevent damage to the body by the buffer action.
이때, 상기 에어백(30) 내부의 내압이 지나치게 높은 경우에 절개부(20)가압력에 의하여 분리되면서 절개부(20)가 절개된다. 따라서, 도 4에 도시된 바와 같이, 가스배출공(15)의 크기는 크게 확대되어 내부의 가스배출량이 증가하게 되어 에어백(10)의 내압은 탑승객(30)을 효과적으로 보호할 정도로 유지되어진다.At this time, when the internal pressure of the inside of the airbag 30 is too high, the cutout portion 20 is separated by the pressure and the cutout portion 20 is cut off. Therefore, as shown in FIG. 4, the size of the gas discharge hole 15 is greatly enlarged to increase the amount of gas discharged therein, so that the internal pressure of the airbag 10 is maintained to effectively protect the occupant 30.
그리고, 상기 절개부(20)의 절개가 진행되다가 절개차단공(25)에 이르러 절개를 멈추게 되므로 절개 상태를 제어하게 되는 것이다.Then, the incision of the incision 20 proceeds to reach the incision blocking hole 25 so that the incision is stopped to control the incision state.
따라서, 상기한 바와 같이 본 발명에 따른 내압조절수단을 구비한 에어백을 사용하게 되면, 에어백의 팽창시에 에어백의 측면부분에 에어백 내부의 압력을 조절하기 위하여 형성시킨 가스배출공에 십자형상으로 절개부를 형성하고, 이 절개부의 끝단부분에 절개를 차단시킬 수 있는 절개차단공을 형성하여 에어백이 불규칙적으로 찢어지는 것을 방지하고, 에어백의 내압조절을 용이하게 하여 탑승객에 손상을 가하는 것을 방지하도록 하는 매우 유용하고 효과적인 발명인 것이다.Therefore, when using the air bag provided with the pressure-resistant control means according to the present invention as described above, incision in the cross-shaped gas discharge hole formed to adjust the pressure inside the air bag on the side portion of the air bag when the air bag is inflated Forming an incision and forming an incision blocking hole at the distal end of the incision to prevent the airbag from tearing irregularly, and to easily control the internal pressure of the airbag to prevent damage to the passengers. It is a useful and effective invention.
