본 고안은 차량실내의 조수석전방에 설치되는 승객에어백의 도어열림장치에 관한 것이다.The present invention relates to a door opening device for a passenger airbag installed in the passenger seat front of the vehicle cabin.
종래의 승객에어백은 제4도와 같이 백과 인플레이터가 내장된 하우징(41)전방에서 가스에 의하여 팽창하는 백(42)의 압력에 의하여 노치부분이 떨어져 나가도록 하우징(41)에 도어양단이 체결되고, 또 이 도어(43)외면은 크래쉬 패드(44)외면과 일치되도록 설치하고 있다. 이러한 승객에어백의 도어(43)는 전개시 하단이 상향으로 젖혀지도록 하고 있기 때문에 도어가 윈드 쉴드 글래스(45)를 때려서 파편이 비산되는 경우가 발생할 수 있고, 어린이가 서 있거나 승객이 에어백에 너무 가까이 있는 경우 약 300KPH(시간당 키로미터)의 속도로 열리는 도어에 맞아 치명적인 부상을 입을 우려가 있었던 것이다. 또한 도어로 인해 백의 전개공간을 방해하므로 에어백의 성능이 저하되는 문제가 있었던 것이다.In the conventional passenger airbag as shown in FIG. 4, both ends of the door are fastened to the housing 41 so that the notch portion is separated by the pressure of the bag 42 expanding by the gas in front of the housing 41 in which the bag and the inflator are built, The outer surface of the door 43 is provided to coincide with the outer surface of the crash pad 44. Since the door 43 of such a passenger airbag has its bottom lowered upward when deployed, the door may hit the windshield glass 45 so that debris may be scattered and a child may stand or the passenger may be too close to the airbag. If there were any, the door would open at a speed of about 300 KPH (kilometres per hour), which could have been fatal. In addition, since the door interferes with the deployment space of the bag, there is a problem that the performance of the air bag is degraded.
본 고안은 도어가 윈드 쉴드 글래스를 때리지 않도록 하고 비정상자세의 승객이 맞지 않도록 하여 백의 전개시 방해가 되지 않도록 할 수 있는 승객에어백 도어열림장치를 제공하는데 그 목적이 있는 것이다.The object of the present invention is to provide a passenger airbag door opening device that can prevent the door from hitting the windshield glass and prevents passengers of abnormal postures from being disturbed when the bag is deployed.
본 고안은 상기 목적을 달성하기 위하여 하단이 떨어져 나가도록 하우징에 장착되는 도어 상단에 노치를 형성하고, 크래쉬 패드와 하우징 상면간에 유동공간을 형성하며, 인플레이터의 일측에 가스압에 의해 밀릴 수 있는 피스톤이 설치된 실린더를 형성하고, 충돌시 상기 노치를 꺾어 상기 유동공간내로 도어가 딸려 들어갈 수 있도록 상기 피스톤과 도어 상단 중앙을 줄로 연결한 것이다.The present invention forms a notch in the upper end of the door mounted to the housing so that the lower end is separated to achieve the above object, to form a flow space between the crash pad and the upper surface of the housing, the piston which can be pushed by gas pressure on one side of the inflator The piston is formed, and the piston is connected to the center of the upper end of the door in a row so as to bend the notch when colliding so that the door can enter the flow space.
이하 실시예 도면에 의하여 설명한다.A description with reference to the following drawings.
제1도 및 제2도에 있어서 부호 1은 도어이고, 2는 하우징, 3은 인플레이터이다.In FIG. 1 and FIG. 2, reference numeral 1 is a door, 2 is a housing, and 3 is an inflator.
도어(1)의 하단은 통상과 같이 하우징(2)하단의 절곡된 플랜지에 끼워져 있고, 그 전방이 도어(1)모서리 부분에는 전개시 백(4)의 팽창압에 의하여 떨어져 나갈 수 있는 절단노치(5)가 횡방향으로 형성되어 있는 바, 이러한 도어(1)의 상단은 통상의 경우보다 길게 형성하여 중간에 노치(6)를 횡방향으로 형성하고, 또 노치(6)하부의 도어(1)양쪽에는 돌기(7,7')를 형성시킨 것이다. 하우징(2)상면과 크래쉬 패드(8)저면간에는 상기 도어(1)가 꺾여 들어갈 수 있는 유동공간(9)이 형성되고 또 인플레이터(3)에서 돌출하는 2개의 실린더(10,10')가 관통할 수 있도록 구멍이 뚫려 있다.The lower end of the door 1 is fitted to the bent flange at the bottom of the housing 2 as usual, and the front notch is cut off to the corner of the door 1 by the expansion pressure of the bag 4 when deployed. Bar 5 is formed in the transverse direction. The upper end of the door 1 is formed longer than usual, and the notch 6 is formed in the transverse direction in the middle, and the door 1 below the notch 6 is formed. On both sides, projections 7 and 7 'are formed. Between the upper surface of the housing 2 and the bottom of the crash pad 8, a flow space 9 through which the door 1 is bent is formed, and two cylinders 10 and 10 'protruding from the inflator 3 pass therethrough. There is a hole for it.
인플레이터(3)는 압축가스식으로서 내부의 가스가 폭발시 피스톤(11,11')을 밀 수 있도록 연관되는 실린더(10,10')가 호상으로 형성되어 있다. 상기 피스톤(11,11')과 도어(1)의 돌기(7,7')간에는 각각 줄(12,12')이 연결되어 있다.The inflator 3 is a compressed gas type and has cylinders 10 and 10 'associated with each other so as to push the pistons 11 and 11' when the gas inside explodes. Rows 12 and 12 'are connected between the pistons 11 and 11' and the projections 7 and 7 'of the door 1, respectively.
상기 인플레이터(3)는 실린더(10,10')와 연통되어 있을 뿐만 아니라 백(4)으로 가스를 내보내기 위한 구멍(13,13')이 각각 형성되어 있다.The inflator 3 is not only in communication with the cylinders 10, 10 ′, but also with holes 13 and 13 ′ for venting gas into the bag 4, respectively.
따라서 제1도와 같은 상태에서 정면충돌에 의하여 인플레이터(3)가 폭발하면 가스가 구멍(13,13')을 통하여 배출되면서 백(4)을 팽창시켜 이 팽창압에 의하여 절단노치(5)를 떨어뜨림과 동시에 피스톤(11,11')을 밀어 줄(12,12')을 당기므로서 노치(6)부분은 꺾어지고 도어(1)상단이 제3도와 같이 유동공간(9)내로 딸려 들어가게 되는 것이다.Therefore, when the inflator 3 explodes by the frontal collision in the state as shown in FIG. 1, the gas is discharged through the holes 13 and 13 'and the bag 4 is expanded to drop the cutting notch 5 by this expansion pressure. At the same time, the notch 6 is bent and the upper part of the door 1 comes into the flow space 9 as shown in FIG. 3 by pulling the strings 12 and 12 'while pushing the pistons 11 and 11'. will be.
이와 같은 본 고안은 도어가 상향으로 젖혀지지 않고 크래쉬 패드와 하우징 사이로 딸려 들어가는 것이기 때문에 윈드 쉴드 글래스를 때릴 염려가 없으며, 어린이가 서 있거나 승객이 크래쉬 패드면에 가까이 있다고 하더라도 어린이나 승객에게 영향을 주지 않아 도어로 인한 부상을 방지하게 되고, 백의 전개시 일단 도어하단이 떨어져 나가면 백에 영향을 주지 않기 때문에 백의 전개시간이 단축되는 효과가 있는 것이다.This invention does not have to worry about hitting the windshield glass because the door does not lean upwards and falls between the crash pad and the housing, and does not affect the child or passenger even if the child is standing or if the passenger is close to the crash pad face. This prevents injuries due to the door, and the deployment time of the bag is shortened because it does not affect the bag once the bottom of the door falls off during deployment of the bag.
