Description

차량의 조수석 에어백 전개장치{Passenger's air bag developing device in vehicle}Passenger's air bag developing device in vehicle

본 발명은 차량의 조수석 에어백에 관한 것으로, 보다 상세하게는 작동시 에어백에 의해 분리·전개되는 도어의 충격 흡수 성능을 높여 부딪히더라도 파손이나 파편등이 발생되지 않도록 된 차량의 조수석 에어백 전개장치에 관한 것이다.The present invention relates to a passenger seat airbag of a vehicle, and more particularly, to a passenger seat airbag deploying apparatus of a vehicle in which damage or debris is not generated even when it is bumped up to increase the shock absorption performance of a door that is separated and developed by an airbag during operation. It is about.

일반적으로 에어백 시스템은 충돌시의 충격을 차체에 설치된 센서로 검출하여 마이컴에 입력하면 충격의 강도에 따라 에어백을 전개시킬지 여부를 판정해 전개 필요시 전기신호를 인플레이터로보내 가스 발생재를 연소시켜서 에어백을 팽창시켜 탑승자를 보호하는 안전장치이다.In general, the airbag system detects the impact of a collision with a sensor installed in the vehicle body and inputs it to the microcomputer to determine whether to deploy the airbag according to the strength of the impact, and if necessary, sends an electrical signal to the inflator to burn the gas generating material by burning the gas generating material. It is a safety device to protect the occupants by inflating them.

이러한 에어백은 승개의 머리 및 흉부를 보호하여 스티어링 휠 또는 윈드글래스에 2차 충돌하는 것을 방지하게 되는데, 차량의 충돌의 형태 및 충돌속도에 의해서 각각 다르지만 통상적으로 충돌로부터 충돌판정까지의 시간은 10ms이고 전기신호가 출력되어 에어백이 완전하게 팽창하기까지의 시간은 30-40ms로 극히 짧은 시간에 이루어져야만 한다. These airbags protect the head and chest of the passengers to prevent secondary collisions with the steering wheel or windglass, which are different depending on the type of collision and the speed of the vehicle. The time for the electrical signal to be output and the airbag to fully inflate should be 30-40ms in a very short time.

즉, 이와 같은 극히 짧은 순간에 에어백은 승객을 멈추게 하여 보호하며 동시에 가스에 배출되는 것에 의해서 에너지를 흡수하면서 줄어드는데, 이러한 모든 작동 완료시간은 약 0.100.15초 정동의 짧은 시간에 이루어진다.That is, at such a very short moment the airbag is reduced by absorbing energy by stopping and protecting the passengers and at the same time being discharged into the gas, all of which are completed in a short time of about 0.100.15 seconds.

또한, 에어백 시스템은 자동차의 일생 동안 한번도 작동하지 않은 경우도 있지만 사고시 확실하게 작동하지 않으면 안되고 반대로 작동이 필요치 않을 때에는 작동하지 않도록 해야 되기 때문에 장치의 높은 신뢰도가 요구됨은 물론이다. In addition, although the airbag system may never operate during the lifetime of the vehicle, it is of course required to operate reliably in the event of an accident and, conversely, when the operation is not necessary, high reliability of the device is required.

한편, 차량 충돌 사고시 조수석에 탑승한 사람은 상체부위가 관성에 의해 전방 윈드 글래스측으로 쏠리게 되므로 크래시패드(crash pad)에 부딪치거나 심한 경우에 앞 유리창에 부딪치는 사고가 발생하게 된다.On the other hand, the person in the passenger seat during the vehicle crash accident is inclined to the front windshield side by the inertia, the crash pad (crash pad) (crash pad) or in case of severe accidents hit the windshield.

이러한 사고로부터 인명을 보호하기 위한 수단으로 조수석용 에어백 장치를 설치하게 되는데 즉, 공기가 주입되지 않은 상태로 접혀져 조수석 전방의 크래시패드 내측으로 내장되어 있다가, 차량이 충돌하게 되면 가스가 에어백 내로 공급되면서 부풀어져 운전석이나 조수석 탑승자의 상체 전면에 전개된다. As a means of protecting human life from such accidents, a passenger airbag device is installed, which is folded without air injection and built into the crash pad in front of the passenger seat. When the vehicle crashes, gas is supplied into the airbag. As it expands, it expands to the front of the driver's or front passenger's upper body.

그러나, 이와 같은 조수석용 에어백은 그 전개 특성상 크래시패드의 일부분인 도어부위가 전개되는 에어백에 의해 분리되면서 전방 윈도 글래스쪽으로 빠르게 이동되는데, 이때 상기 도어가 전방 윈드 글래스에 부딪히게 되는 경우에는(특히 어드밴스드 에어백 타입의 조수석용 에어백의 경우 빈번하게 발생됨)도어의 전개 속도로 인해 도어가 균열되거나 파손되면서 그 파편(PPF 재질임)으로 인해 승객에게 2차 부상을 입히는 현상이 있게 된다.However, such a passenger seat airbag is rapidly moved toward the front window glass while being separated by the airbag in which the door part, which is a part of the crash pad, is deployed, in which case the door hits the front windglass (especially the advanced). Airbag-type passenger airbags are frequently generated.) The door is cracked or broken due to the speed of the door, which causes secondary injury to passengers due to the fragments (PPF material).

또한, 전개되는 에어백에 의해 분리되면서 펼쳐지는 크래시패드의 도어부위는 전개시 크래시패드로부터 용이하게 분리될 수 있도록 티어선(Tear Line)이 그 단면에 수직하게 형성되는데, 이와 같은 티어선은 조수석 에어백이 충족되어야 만 하는 법규를 불 만족시키는 요인 즉, 헤드 임펙트 테스트(Head Impact Test)시와 같이 외부로부터 티어선부위로 충격을 가했을 때 티어선이나 그 형성부위에 파손이 형성되지 않아야 함에도 불구하고 단면에 수직하게 형성된 티어선이 파단되는 현상이 있어 법규를 만족시키기가 매우 어려운 한계를 갖게 된다.In addition, a tear line is formed perpendicular to the cross-section so that the door portion of the crash pad that is separated by the deployed air bag can be easily separated from the crash pad at the time of deployment. This impairs the law that must be met, i.e. when the impact is applied to the tier line from the outside, such as in the Head Impact Test, no damage should be made to the tier line or its formation. There is a phenomena of breaking the vertically formed tier line has a very difficult limit to satisfy the law.

이에 본 발명은 상기와 같은 점을 감안하여 발명된 것으로, 에어백 전개시 분리되면서 전개되는 도어의 충격에 대한 흡수·완충 정도를 높여 파편에 의한 승객의 2차 부상을 방지함은 물론 헤드 임펙트 테스트시에도 티어선의 파손을 방지해 조수석 에어백에 대한 법규를 만족함에 그 목적이 있다.Accordingly, the present invention has been in view of the above-mentioned matters, and it is possible to prevent secondary injury of passengers due to debris by increasing the degree of absorption and cushioning against the impact of the door that is developed while the airbag is deployed, as well as during the head impact test. Its purpose is to satisfy the legislation for passenger seat airbags by preventing damage to the tier ship.

상기와 같은 목적을 달성하기 위한 본 발명은, 운전석을 이루는 크래시패드내에 수용된 에어백의 전개수단이 크래시패드로부터 분리되도록 티어부가 형성됨과 더불어 그 내부로 보강부재를 구비한 전개도어와, The present invention for achieving the above object is a deployment door having a reinforcing member in addition to the tier formed so that the deployment means of the airbag accommodated in the crash pad forming the driver's seat from the crash pad,

이 전개도어의 하부에 위치되어 에어백을 가려주면서 에어백전개시 전개도어를 밀어 분리시켜주는 도어플레이트, Located at the bottom of the deployment door to cover the air bag while pushing the deployment door to release the air bag, the door plate,

에어백전개시 분리되는 도어플레이트를 잡아 주도록 일단이 도어플레이트의 하부에서 고정되면서 타단이 크래시패드내부에서 고정된 도어브라켓, Door bracket fixed at the inside of the crash pad while the other end is fixed at the bottom of the door plate to hold the door plate to be separated during the air bag deployment,

상기 크래시패드내부에서 도어플레이트의 측면 둘레를 감싸면서 전개도어의 티어부부위를 지지하는 도어슈트 및 A door suit supporting the tier of the deployment door while surrounding the side circumference of the door plate in the crash pad;

이 도어슈트에 스크류등을 매개로 고정되면서 에어백을 수용하는 에어백모듈하우징으로 이루어진 것을 특징으로 한다. The door chute is fixed via a screw or the like, characterized in that made of an airbag module housing for receiving the airbag.

이하 본 발명의 실시예를 첨부된 예시도면을 참조로 상세히 설명한다.Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

도 1은 본 발명에 따른 차량의 조수석 에어백 장치 구성도이고, 도 2는 본 발명에 따른 조수석 에어백 전개장치의 단면 구성도를 도시한 것인바, 본 발명은 운전석을 이루는 크래시패드(2)의 조수석부위에 조향휠(1)에 장착된 운전자용 에어백(1')과 연결되어 작동되는 조수석용 에어백(10)과, 이 에어백(10)을 감싸 지지하면서 에어백(10)전개시 에어백 쿠션의 압력으로 인해 찢어지면서 크래시패드(2)로부터 분리되어 에어백 쿠션이 크래시패드(2)로부터 팽창되어 승객을 보호하는 전개수단으로 이루어지게 된다.1 is a configuration diagram of a passenger seat airbag device of a vehicle according to the present invention, Figure 2 is a cross-sectional configuration diagram of a passenger seat airbag deployment device according to the present invention, the present invention is a passenger seat of a crash pad (2) forming a driver's seat Passenger's seat airbag 10, which is connected to the driver's airbag 1 'mounted on the steering wheel 1, and the airbag 10 while being wrapped and supported by the airbag cushion at the time of the airbag 10 deployment. Due to the tearing, the airbag cushion is separated from the crash pad 2 and is expanded from the crash pad 2 to form a deployment means for protecting the passenger.

여기서, 상기 전개수단은 도 2에 도시된 바와 같이 에어백(10)의 전개시 에어백 쿠션의 압력으로 인해 찢어지면서 크래시패드(2)로부터 분리되도록 티어(Tear)부(11")가 형성됨과 더불어 그 내부로 연질 재질(EX.TPO(Thermo Plastic Olefin)로 이루어진 보강부재(11')를 구비한 PPF(Polypropylene 계열의 복합PP수지)재질인 전개도어(11)와, 이 전개도어(11)의 하부에 위치되어 에어백(10)을 가려주면서 에어백(10)전개시 전개도어(11)를 밀어 분리시켜주는 도어플레이트(14), 에어백(10)전개시 분리되는 도어플레이트(14)를 잡아 주도록 일단이 도어플레이트(14)의 하부에서 고정되면서 타단이 크래시패드(2)내부에서 고정된 도어브라켓(13), 상기 크래시패드(2)내부에서 도어플레이트(14)의 측면 둘레를 감싸면서 전개도어(11)의 티어부(11")부위를 지지하는 도어슈트(12) 및 이 도어슈트(12)에 스크류등을 매개로 고정되면서 에어백(10)을 수용하는 에어백모듈하우징(15)으로 이루어진다.Here, as shown in FIG. 2, a tear part 11 ″ is formed to be separated from the crash pad 2 while being torn due to the pressure of the airbag cushion when the airbag 10 is deployed. A development door 11 made of a PPF (polypropylene-based composite PP resin) material having a reinforcement member 11 'made of EX.TPO (Thermo Plastic Olefin) and a lower part of the development door 11 The door plate 14, which covers the air bag 10 and slides the deployment door 11 at the time of deployment of the air bag 10, is closed at one end to hold the door plate 14 that is separated when the air bag 10 is developed. The door bracket 13 fixed at the bottom of the door plate 14 and the other end is fixed inside the crash pad 2, and the deployment door 11 while surrounding the side circumference of the door plate 14 inside the crash pad 2. Door chute 12 supporting the tier 11 " It is made of airbag module housing (15) for accommodating the airbag 10 while being fixed via a screw or the like.

그리고, 상기 전개도어(11)의 티어부(11")는 에어백(10)전개시 크래시패드(2)로부터 분리시켜주는 기능을 하게 되므로 바깥쪽으로 경사지게 소정각도(a)를 갖고 크래시패드(2)에 형성되는데, 이와 같이 상기 티어부(11")가 밖으로 경사지게 형성되는 것은 에어백 전개시 전개도어(11)의 안정적인 작용을 확보하는 역할을 하게 된다.Further, since the tier part 11 "of the deployment door 11 functions to separate from the crash pad 2 when the air bag 10 is developed, the crash pad 2 has a predetermined angle a to be inclined outward. In this case, the tier 11 ″ is formed to be inclined out so as to secure a stable action of the deployment door 11 when the airbag is deployed.

즉, 상기 전개도어(11)의 티어부(11")에 법규상으로 적용되는 HIT(Head Impact Test)시험을 하게 되는데 이는, 차량 충돌시 승객의 머리부위가 상기 전개도어(11)의 티어부(11")를 형성하는 크래시패드(2)부위에 부딪힐 때 가해지는 헤드충격력(F)에 의해 변형되어 에어백의 작동 불량등을 방지하기 위한 것임은 물론이다.That is, a HIT (Head Impact Test) test is applied to the tier part 11 "of the deployment door 11 in accordance with the law. In this case, the passenger's head part of the deployment door 11 is tier part of the deployment door 11. Of course, it is deformed by the head impact force F applied when it hits the portion of the crash pad 2 forming the " 11 "

또한, 상기 전개도어(11)의 내부에 구비된 보강부재(11')는 에어백(10)전개시 크래스패드(2)로부터 분리되면서 전방 글래스에 부딪힐 때 가해지는 글래스충격력(P)을 흡수하게 되는데 즉, 상기 전개도어(11)재질인 PPF에비해 상대적으로 연질재인 보강부재(11')가 글래스충격력(P)을 흡수·완충해 전개도어(11)의 파손을 방지하여 파손시 발생될 수 있는 승객의 2차 부상을 방지하게 됨은 물론이다.In addition, the reinforcing member 11 ′ provided in the deployment door 11 absorbs the glass impact force P applied when the airbag 10 is hit by the front glass while being separated from the crash pad 2 when the airbag 10 is opened. That is, the reinforcing member 11 ', which is a relatively soft material, absorbs and buffers the glass impact force P to prevent the breakage of the deployment door 11, compared to PPF, which is a material of the development door 11, so that it may be generated when it is broken. Of course, it prevents secondary injuries of passengers.

그리고, 상기 도어슈트(12)와 도어플레이트(14)는 각각 크래시패드(2)의 하부에서 진동용접(Vibration Welding)되고, 상기 도어플레이트(14)와 도어브라켓(13)은 서로 진동용접(Vibration Welding)이나 초음파 융착 방식으로 고정되어진다.In addition, the door chute 12 and the door plate 14 are vibration welding at the bottom of the crash pad 2, respectively, and the door plate 14 and the door bracket 13 are vibration welding with each other. It is fixed by welding or ultrasonic welding method.

이하 본 발명의 작동을 첨부된 도면을 참조로 상세히 설명한다.Hereinafter, the operation of the present invention will be described in detail with reference to the accompanying drawings.

본 발명의 조수석용 에어백(10)은 통상적으로 차량의 충돌시 이를 감지한 콘트롤러로부터 제어신호를 받아 폭발하는 인플레이터의 분사 가스에 의해 에어백 쿠션이 크래시패드(2)로부터 팽창되면서 전개되면서 승객을 보호하게 됨은 물론이다.The passenger seat airbag 10 of the present invention typically receives a control signal from a controller that detects a collision of the vehicle, and protects the passenger while the airbag cushion is inflated from the crash pad 2 by the injection gas of the inflator that explodes. Of course.

이때, 본 발명의 에어백(10)은 전개시 전개도어(11)가 승객의 보호 작용에 방해될 수 있는 문제없이 크래시패드(2)로부터 초기 설계된 상태로 절단되면서 분리되도록 함은 물론, 또한 에어백(10)이 급격하게 전개될 때 크래시패드(2)로부터 분리된 전개도어(11)의 파편에 의한 2 차적인 승객 부상을 방지하게 됨은 물론이다.At this time, the airbag 10 of the present invention is to be separated from the crash pad 2 in the initial designed state without the problem that the deployment door 11 may interfere with the protective action of the passenger during deployment, as well as the airbag ( Of course, the secondary passenger injury caused by the fragmentation of the deployment door 11 separated from the crash pad 2 is prevented when 10) is rapidly deployed.

즉, 본 발명의 전개도어(11)는 에어백 전개시 전개도어(11)의 안정적인 작용을 확보하도록 크래시패드(2)로부터 전개도어(11)를 분리시켜주는 티어부(11")부위에 대해 HIT(Head Impact Test)시험인 크래시패드(2)부위로 가해지는 헤드충격력(F)에 의한 전개도어(11)의 티어부(11")부위가 변형여부를 판단하게 되고, 이와 같은 HIT(Head Impact Test)시험을 통해 전개도어(11)의 티어부(11")부위를 소정각도(a)로 경사지게 형성시켜 만약, 에어백(10)의 작동전 승객등에 의해 전개도어(11)의 티어부(11")부위에 충격이 가해지더라도 에어백의 안정적인 작동을 유지 할 수 있게 됨은 물론이다.That is, the deployment door 11 of the present invention has a HIT for the tier portion 11 ″ which separates the deployment door 11 from the crash pad 2 so as to secure a stable action of the deployment door 11 when the airbag is deployed. (Head Impact Test) It is determined whether the tier portion 11 "of the deployment door 11 is deformed by the head impact force F applied to the crash pad 2, which is a test, and such HIT (Head Impact Test). Tear part 11 "of the deployment door 11 is formed to be inclined at a predetermined angle (a) by a test, and if the tier part 11 of the deployment door 11 is operated by a passenger or the like before operation of the airbag 10 Even if an impact is applied to the part, the airbag can maintain stable operation.

또한, 에어백(10)작동시 크래시패드(2)로부터 도어플레이트(14)와 함께 급격하게 분리되는 전개도어(11)가 전면 글래스에 부딪혀 글래스충격력(P)을 받는 경우에도, 상기 전개도어(11)의 내부에 구비된 보강부재(11')가 전개도어(11)재질인 PPF에비해 상대적으로 연질재로 이루어져 가해지는 글래스충격력(P)을 흡수·완충해 전개도어(11)의 파손을 방지하게 되고 이에 따라, 상기 전개도어(11)와 전방 글래스간의 충돌로 인한 파손을 방지해 전개도어(11)의 파편에 의해 발생될 수 있는 승객의 2차 부상을 방지하게 됨은 물론이다.In addition, even when the deployment door 11 that is suddenly separated from the crash pad 2 together with the door plate 14 during the operation of the airbag 10 hits the front glass and receives the glass impact force P, the deployment door 11 ), The reinforcing member 11 'provided inside the absorber absorbs and buffers the glass impact force P applied by the soft material relatively to the PPF, which is a material of the development door 11, to prevent damage of the development door 11. As a result, the secondary door may be prevented from being damaged by the collision between the deployment door 11 and the front glass to prevent secondary injuries of passengers, which may be caused by the fragmentation of the deployment door 11.

이상 설명한 바와 같이 본 발명에 의하면, 에어백 전개시 크래시패드로부터 분리되는 전개도어가 유연성이 서로 다른 이종재질로 이루어지면서 전개도어 분리를 위한 티어부도 경사지게 형성시켜,에어백 전개시 분리되면서 전개되는 도어의 충격에 대한 흡수·완충 정도를 높여 파손시 발생되는 파편에 의한 승객의 2차 부상을 방지함은 물론 헤드 임펙트 테스트시에도 티어선의 파손을 방지해 조수석 에어백에 대한 법규를 만족과 함께 안정적인 작동 성능을 유지할 수 있는 효과가 있게 된다.As described above, according to the present invention, the deployment door separated from the crash pad when the airbag is deployed is made of a different material with different flexibility, so that the tier for separating the deployment door is also formed to be inclined, and the impact of the door that is developed while separating the airbag is deployed. It prevents the passenger from secondary injury due to debris generated during breakage by increasing the degree of absorption and buffering, and also prevents damage to the tier wire during the head impact test, and maintains stable operation performance while satisfying the regulations for the passenger seat airbag. It can be effective.
