Description

자동차용 조수석 에어백과 그 전개 방법{Air Bag For Vehicle And Unfolding Method}Passenger's seat airbag for automobile and its deployment method {Air Bag For Vehicle And Unfolding Method}

본 발명은 자동차 충돌시 정면으로부터의 충격을 완화하기 위한 에어백에 관한 것으로, 특히 에어백 쿠션의 전개를 유도하여 승객에게 압력이 가해지지 않도록 유도부재를 갖는 자동차 조수석용 에어백과 그 전개 방법에 관한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an airbag for mitigating an impact from the front when a vehicle crashes, and more particularly, to an automobile passenger seat airbag having an induction member so that pressure is not applied to a passenger by inducing the deployment of an airbag cushion and a method of deploying the same.

일반적으로, 에어백은 자동차에 쓰이는 것으로 충돌사고가 났을 때 생기는 충격력이나 고속주행중의 급정거를 감지할 수 있는 센서를 구비하여, 사고시 충격 강도에 따른 센서의 신호에 따라 에어백 속에 팽창가스를 주입하여 급속히 팽창시킴으로써 운전자는 물론 탑승자를 부상으로부터 최대한 보호하기 위한 안전장치이다.In general, the airbag is used in automobiles and has a sensor that can detect the impact force generated in a crash accident or sudden stop during high-speed driving, and inflate rapidly by injecting an inflation gas into the airbag according to the signal of the sensor according to the impact intensity in case of an accident. This is a safety device to protect the driver as well as the passenger from injury.

또한, 자동차를 사용함에 있어 에어백은 한번도 작동하지 않을 수도 있지만 사고시에는 정상적으로 작동해야 하며, 작동하지 않아야 할 때 오작동 되는 일이 없어야 하므로 장치의 높은 신뢰도가 요구되는 안전장치이다.In addition, in using a car, the airbag may never operate, but in case of an accident, the airbag should operate normally, and when it should not operate, it should not malfunction so it is a safety device that requires high reliability of the device.

이러한 에어백은 통상적으로 운전석의 스티어링휠과 조수석의 인스트루먼트패널에 각각 설치되고, 차량의 충돌시 충돌감지센서와 전자제어유닛에 의해 안전벨 트와 같이 연동되어 탑승자를 부상으로부터 최대한 보호하게 된다.These airbags are typically installed on the steering wheel of the driver's seat and the instrument panel of the passenger seat, respectively, and interlocked together with seatbelts by a collision detection sensor and an electronic control unit in the event of a vehicle collision to protect the occupant from injury as much as possible.

즉, 차량의 충돌시, 충돌감지센서가 이의 감지신호를 전자제어유닛(ECU)으로 출력하고, 상기 전자제어유닛(ECU)은 충격강도에 따라 에어백의 작동 여부를 판단하여 에어백을 작동시킬 필요가 있을 때에는 인플레이터를 작동시켜 에어백을 팽창시킨다.That is, in the event of a collision of the vehicle, the collision detection sensor outputs its detection signal to the electronic control unit (ECU), and the electronic control unit (ECU) needs to determine whether the air bag is operated according to the impact strength to operate the air bag. If present, operate the inflator to inflate the airbag.

이때, 인플레이터는 에어백에 연결되어 있어, 전자제어유닛(ECU)에 의해 그 내부의 점화장치에 의해 화약을 착화시키고 가스 발생제를 연소시킴으로써, 순간적으로 발생된 다량의 가스가 에어백으로 주입되어 에어백을 급속하게 팽창시키게 된다.At this time, the inflator is connected to the airbag, and the electronic control unit (ECU) ignites the gunpowder by the ignition device therein and burns the gas generating agent. It expands rapidly.

이때, 에어백은 접혀진 순서에 따라 순차적으로 전개되고, 에어백 쿠션 내측에 봉제된 테더에 의해 에어백 쿠션이 전개되었을 때 그 형상을 제한하며, 전개된 쿠션에 의해 탑승자를 보호할 수 있도록 한다.At this time, the airbags are sequentially deployed in the folded order, and the airbag cushion is limited when the airbag cushion is deployed by the tether sewn inside the airbag cushion, and the occupant is protected by the deployed cushion.

그러나 종래의 자동차용 조수석 에어백은 전개가 거의 이루어진 후 에어백 쿠션의 내부에 고정된 테더에 의해 에어백 형상이 제한되고, 앞 유리의 각도에 따라 전개성을 유도하고 제한하는 데는 어려움이 있었다.However, the conventional passenger front airbag is limited to the airbag shape by a tether fixed inside the airbag cushion after the deployment is almost completed, and there is a difficulty in inducing and limiting the deployability according to the angle of the windshield.

즉, 스포츠카와 같은 경우 앞유리의 각도가 일반 승용차의 각도보다 작아 에어백 전개시 앞유리에 의해 가스의 압력이 앞유리와 맞닿은 반대편에 집중되어 하향전개된다.That is, in the case of a sports car, the angle of the windshield is smaller than that of a general passenger car, so that the pressure of the gas is concentrated downward on the opposite side of the windshield when the airbag is deployed.

이에 따라, 에어백 쿠션의 초기 전개에 의해 발생되는 충격으로 에어백에 근접하게 탑승한 탑승객 즉, 인스트루먼트 패널에 근접하게 탑승한 탑승객이나 비정상적인 자세로 탑승한 어린이, 유아가 상해를 입는 것을 방지하는 데 어려움이 있었다. Accordingly, it is difficult to prevent injuries of passengers who are in close proximity to the airbag due to the impact caused by the initial deployment of the airbag cushion, that is, passengers who are in close proximity to the instrument panel, children in an abnormal posture, or infants. there was.

본 발명의 목적은 상술한 바와 같은 문제점을 해결하기 위한 것으로서, 에어백 쿠션이 전개될 때 하측에서 유도부재가 함께 배출되어 하향전개를 방지하고, 에어백 쿠션의 초기 전개성을 유도할 수 있어 탑승객을 보호하는 자동차용 조수석 에어백과 그 전개 방법을 제공하는 것이다.An object of the present invention is to solve the problems as described above, when the airbag cushion is deployed, the induction member is discharged together from the lower side to prevent downward development, induce the initial deployment of the airbag cushion to protect the passengers To provide a passenger passenger airbag and its deployment method.

상기 목적을 달성하기 위해 본 발명의 자동차용 조수석 에어백과 그 전개 방법은 자동차용 조수석 에어백에 있어서, 상기 에어백을 구성하는 에어백 쿠션 일측에는 유도부재가 설치된 것을 특징으로 한다.In order to achieve the above object, the passenger seat airbag for automobile and the deployment method thereof of the present invention are characterized in that the induction member is installed on one side of the airbag cushion constituting the airbag in the passenger seat airbag for automobile.

또한, 상기 유도부재는 에어백 쿠션보다 먼저 전개되는 것을 특징으로 한다.In addition, the guide member is characterized in that it is deployed earlier than the airbag cushion.

또한, 상기 유도부재는 에어백 쿠션의 앞쪽에서 전개되도록 에어백 쿠션이 전개되는 방향 앞쪽에 설치되는 것을 특징으로 한다.In addition, the induction member is characterized in that it is installed in the front of the airbag cushion deployment direction to be deployed in front of the airbag cushion.

또한, 상기 유도부재는 코팅된 패브릭 원단인 것을 특징으로 한다.In addition, the induction member is characterized in that the coated fabric fabric.

또한, 상기 유도부재는 봉제 또는 본딩을 통해 고정되는 것을 특징으로 한다.In addition, the guide member is characterized in that it is fixed through sewing or bonding.

그리고, 자동차용 에어백 쿠션의 전개 방법에 있어서 에어백 쿠션은 유도부재에 의해 상부로 전개되어 차량의 앞쪽 유리와 맞닿는 제1단계, 탑승객을 타고 넘 어 전개되는 제2단계로 이루어진 것을 특징으로 한다.In the deployment method of the airbag cushion for automobiles, the airbag cushion is developed by the guide member upwardly, and is made of a first step of contacting the front glass of the vehicle and a second step of being deployed over the passenger.

상술한 바와 같이, 본 발명에 따른 자동차용 조수석 에어백과 그 전개 방법에 의하면, 유도부재에 의해 에어백 쿠션의 초기 전개성을 유도하여 하향전개되지 않고 상부로 전개되도록 조절하여 에어백 쿠션의 초기 팽창력에 의해 탑승자가 상해를 입는 것을 방지한다.As described above, according to the passenger seat airbag for a vehicle according to the present invention and the method of deploying the same, the induction member induces the initial deployment of the airbag cushion by adjusting it to be deployed upwards without downward development by the initial inflation force of the airbag cushion. Prevent passengers from getting injured.

또한, 인스트루먼트 패널에 근접하게 탑승한 탑승객의 반동으로 인해 상해를 입지 않도록 자세를 구속하여 탑승객을 보호한다.In addition, it protects the passengers by restraining their postures so as not to be injured by the recoil of the passengers in close proximity to the instrument panel.

이하, 첨부한 도면에 의거하여 본 발명의 양호한 실시예들을 상세히 설명한다.Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

또한, 본 발명에 따른 에어백은 조수석의 탑승자를 보호하기 위한 에어백을 그 일례로 들어 설명하나, 이에 한정되는 것은 아니다.In addition, the airbag according to the present invention is described as an example of an airbag for protecting a passenger of a passenger seat, but is not limited thereto.

본 발명에 따른 에어백 모듈은 도 2에 도시된 바와 같이, 에어백 쿠션(10)의 하측에 브릿징 플랩(이하, '유도부재(20)'라 한다)을 고정하여 조수석(60) 앞에 위치한 인스트루먼트 패널(50)에 설치한다.Air bag module according to the present invention, as shown in Figure 2, the instrument panel located in front of the passenger seat 60 by fixing the bridging flap (hereinafter referred to as "induction member 20") to the lower side of the airbag cushion 10 Install in 50.

상기 유도부재(20)는 에어백 하우징(40) 내측에 안착하는 에어백 쿠션(10) 일측에 고정되고, 패브릭을 소재로 하며, 에어백 쿠션(10)이 미끄러지기 용이하도록 코팅 원단을 사용한다.The induction member 20 is fixed to one side of the airbag cushion 10 seated inside the airbag housing 40, made of a fabric, and using a coated fabric so that the airbag cushion 10 is slippery.

또한, 유도부재(20)는 에어백 쿠션(10)의 하측에 고정되어 에어백 쿠션(10) 이 전개되었을 때 유도부재(20)가 에어백 쿠션(10)의 아래쪽에 위치하도록 한다.In addition, the induction member 20 is fixed to the lower side of the airbag cushion 10 so that the induction member 20 is positioned below the airbag cushion 10 when the airbag cushion 10 is deployed.

그리고, 접혀져 있는 에어백 쿠션(10)이 전개되는 방향 쪽에 유도부재(20)가 접혀져 있어 에어백 쿠션(10)이 전개될 때 에어백 쿠션(10)보다 앞서 펼쳐질 수 있도록 한다.Then, the induction member 20 is folded in the direction in which the folded airbag cushion 10 is deployed so that the airbag cushion 10 may be deployed before the airbag cushion 10 when the airbag cushion 10 is deployed.

상기와 같은 구조로 형성된 본 발명에 따른 자동차용 에어백의 작동은 다음과 같다.Operation of the vehicle airbag according to the present invention formed in the above structure is as follows.

우선, 사고 등과 같은 상황에서 차량의 충돌을 감지하여 에어백(A)이 작동하고, 인플레이터(30)에 의해 에어백 쿠션(10) 내로 가스가 주입되며, 이에 따라 에어백 쿠션(10)이 팽창한다.First, the airbag A is activated by detecting a collision of the vehicle in a situation such as an accident, and gas is injected into the airbag cushion 10 by the inflator 30, thereby expanding the airbag cushion 10.

이때, 도 2에 도시된 바와 같이 탑승자가 비정상적인 자세로 인스트루먼트 패널(50)에 근접하게 앉아있거나, 조수석에서 인스트루먼트 패널(50)에 근접하게 앉은 어린이일 경우 탑승자는 인스트루먼트 패널(50)에 부딪히게 되더라도 큰 충격이 가해지지 않게 된다.In this case, as shown in FIG. 2, when the occupant is a child sitting close to the instrument panel 50 in an abnormal posture or a child seated close to the instrument panel 50 in the passenger seat, the occupant may bump into the instrument panel 50. No big impact will be applied.

이와 같이, 인스트루먼트 패널(50)에 근접하게 앉은 탑승자를 충격으로부터 보호하기 위해서는 탑승자가 인스트루먼트 패널(50)에 부딪힌 후 충격에 따른 반동으로 뒤로 젖혀진 후 다시 인스트루먼트 패널(50)에 부딪히지 않도록 탑승자의 자세를 구속하고, 에어백 쿠션(10)이 초기 팽창에 의해 인스트루먼트 패널(50)에 근접한 탑승객이 다치지 않게 초기에 상측으로 전개되도록 하는 것이 탑승자를 보다 효과적으로 보호할 수 있게 된다.As described above, in order to protect the occupant sitting close to the instrument panel 50 from impact, the occupant's posture so that the occupant does not collide with the instrument panel 50 after being bumped back by the recoil according to the impact after hitting the instrument panel 50. It is possible to more effectively protect the occupant so that the airbag cushion 10 is initially deployed upward so that the occupant close to the instrument panel 50 is not injured by the initial inflation.

이를 위해 본 발명의 에어백 쿠션(10)은 제1단계로 에어백 쿠션(10)이 초기 에 상부로 전개되고(도 2a) 그 후, 제2단계로 탑승객을 타고 넘어 전개되도록(도 2 b-e) 에어백 쿠션(10)의 앞쪽 즉, 에어백 쿠션(10)이 전개되는 방향으로 유도부재(20)를 설치한다.To this end, the airbag cushion 10 of the present invention is an airbag such that the airbag cushion 10 is initially deployed upward in a first step (FIG. 2A) and then deployed over the passengers in a second step (FIG. 2B). The guide member 20 is installed in front of the cushion 10, that is, in the direction in which the airbag cushion 10 is deployed.

따라서, 접혀진 에어백 쿠션(10)의 앞쪽에 위치하여 접혀있던 유도부재(20)는 에어백 쿠션(10)이 팽창함에 따라 밀려 에어백 쿠션(10)보다 먼저 전개되어 펼쳐지고, 상기 전개된 유도부재(20)에 의해 에어백 쿠션(10)이 미끄러지며 전개된다.Therefore, the induction member 20, which is folded and positioned in front of the folded airbag cushion 10, is pushed as the airbag cushion 10 expands to be deployed and deployed before the airbag cushion 10, and the deployed induction member 20 is The airbag cushion 10 slides and is deployed.

즉, 에어백 쿠션(10)보다 앞서 전개되는 유도부재(20)는 에어백 쿠션(10)이 전개되는 초기에 에어백 쿠션(10)이 하향전개되지 않고 상부로 전개되도록 유도하여 에어백 쿠션(10)이 하향전개되어 비정상적으로 탑승한 탑승객과 충돌하여 탑승객이 상해를 입는 것을 방지한다.That is, the induction member 20 deployed in advance of the airbag cushion 10 induces the airbag cushion 10 to be deployed upward without downward development at the initial stage when the airbag cushion 10 is deployed so that the airbag cushion 10 moves downward. It will collide with an abnormally occupant and prevent passengers from getting injured.

상기와 같은 유도부재(20)가 전개되고 에어백 쿠션(10)이 전개되는 것은 매우 빠른 시간 안에 일어나므로 유도부재(20)가 패브릭 원단으로 형성되었다 하여도 에어백 쿠션(10)이 유도부재(20)를 따라 미끄러져 전개된다.Since the induction member 20 is deployed and the airbag cushion 10 is developed in a very fast time, the airbag cushion 10 is the induction member 20 even if the induction member 20 is formed of a fabric fabric. Slide along.
