차량용 커튼에어백{Curtain Air Bag for Vehicle}Curtain Air Bag for Vehicle {Curtain Air Bag for Vehicle}

본 발명은 커튼에어백의 하단부가 도어 트림의 길이 방향을 따라 밀착된 상태로 유지되어 탑승객의 머리 상해를 예방하기 위한 차량용 커튼에어백에 관한 것이다.The present invention relates to a curtain airbag for a vehicle for keeping the lower end of the curtain airbag in close contact with the longitudinal direction of the door trim to prevent head injuries of the passengers.

일반적으로 자동차의 기능성 및 편의성과 더불어 탑승객의 안전에 대한 관심이 높아지면서, 자동차 사고시 탑승객을 안전하게 보호할 수 있는 안전과 관련된 장치들의 중요성이 점차 증대되고 있는 추세이다. In general, as the interest in the safety of the passengers as well as the functionality and convenience of the vehicle is increasing, the importance of safety-related devices that can safely protect the passengers in the event of an automobile accident is increasing.

이러한 안전장치들 중에서, 특히 에어백 시스템은 안전밸트와 함께 사용되어 자동차의 정면충돌이나 측면충돌시 탑승객이 상해를 방지하는 기능을 수행하고 있다.Among these safety devices, in particular, the airbag system is used together with the safety belt to prevent passengers from injuring in the front or side collision of the vehicle.

상기와 같은 에어백 시스템 중에서, 커튼에어백(Curtain Air-bag)은 일반적으로 차실내의 측상단을 따라 설치되어 차량 충돌시 커튼식으로 전개되는 구조를 취하고 있다.Among such airbag systems, curtain airbags (Curtain Air-bag) is generally installed along the top side in the interior of the vehicle has a structure that is deployed in a curtain type when the vehicle crashes.

특히, 자동차의 측면 충돌뿐만이 아니라 자동차의 전복 사고시에도 그 효과를 발휘하여 탑승자에게 고도의 안전성을 제공하고 있다.In particular, not only the side collision of the car but also the effect of overturning the car to provide a high level of safety to the occupants.

종래의 커튼에어백은 자동차 실내의 루프레일을 따라 일정구간에 걸쳐서 에어쿠션이 배치되고, 상기 에어쿠션을 루프레일상에 고정하도록 상기 에어쿠션의 상단을 따라 쿠션홀더가 구비되며, 상기 에어쿠션의 일측에 연결 설치되어 상기 에어쿠션을 전개 작동시키는 인플레이터를 포함하여 구성된다.Conventional curtain airbags are disposed in the air cushion over a certain section along the roof rail of the vehicle interior, cushion holder is provided along the top of the air cushion to fix the air cushion on the roof rail, one side of the air cushion It is connected to is configured to include an inflator installed to operate the air cushion.

상기와 같이 구성되는 종래의 커튼에어백은 차량사고 발생시에 인플레이터에서 공급된 작동가스가 상기 에어쿠션 내부로 주입되면서 상기 에어쿠션이 일정형상으로 팽창되어 차량에 탑승한 탑승객을 보호하게 된다.In the conventional curtain airbag configured as described above, the operating gas supplied from the inflator is injected into the air cushion in the event of a vehicle accident, and the air cushion is expanded in a predetermined shape to protect passengers in the vehicle.

그러나, 종래의 커튼에어백은 인플레이터에서 작동가스가 에어쿠션 내부로 주입되면서 상기한 커튼에어백이 전개 작동될 때 하단부의 텐션력이 약하여 탑승자의 머리가 커튼에어백의 외측으로 이탈되어 상기한 탑승자의 심각한 상해를 유발할 수 있는 문제점을 안고 있었다.However, the conventional curtain airbag has a low tension force at the bottom when the curtain airbag is deployed and operated by injecting the working gas into the air cushion. Had a problem that could cause.

이러한 커튼에어백 하단부의 텐션력 저하에 따른 탑승자의 상해를 최소화하기 위해 업체에서는 다양한 방도로 노력 중에 있으며, 일부 국가에서는 법규로 규정하여 탑승자의 머리 이탈이 발생할 경우에 불합격 처리하는 경우가 있어 이에 대한 대책을 필요로 하였다.In order to minimize the injuries of the occupants due to the decrease in tension of the lower part of the curtain airbag, companies are making various efforts, and in some countries, regulations are required in case of departure of the occupant's head due to regulations. It was necessary.

첨부된 도 1 내지 도 3을 참조하면, 차량의 사이드 레일부에 설치되어 차 실내를 향해 커튼에어백(1)이 전개 작동되되,1 to 3, the curtain airbag (1) is installed in the side rail portion of the vehicle toward the vehicle interior deployment operation,

상기한 커튼에어백(1)의 에어쿠션(2) 하단부 내측에 길이방향을 따라 자성체(110)가 구비된 접착부(100); 및 도어 트림(3)의 길이 방향 내측에 설치되며 상기한 접착부(100)가 설치된 에어쿠션(2)이 차 실내를 향해 전개 작동될 때 전원이 인가되어 상기한 에어쿠션(2)의 접착부(100)와 자화(磁化)되는 자력부(200)에 의해 상기한 에어쿠션(2)의 접착부(100)가 도어 트림(3)의 길이 방향에 밀착되도록 구성된다.An adhesive part 100 provided with a magnetic material 110 along a length direction inside the lower end of the air cushion 2 of the curtain air bag 1; And when the air cushion 2 is installed inside the longitudinal direction of the door trim (3) and the adhesive portion 100 is installed deployed toward the interior of the car, power is applied to the adhesive portion 100 of the air cushion (2). ) And the adhesive portion 100 of the air cushion 2 is in close contact with the longitudinal direction of the door trim 3 by the magnetic force portion 200 to be magnetized.

본 발명에 의한 자력부(200)는 제어부에 의해 전원이 인가되도록 구성되며, 차량 충돌시 커튼에어백(1)의 작동과 함께 전원이 인가되도록 구성된다.The magnetic force unit 200 according to the present invention is configured such that power is applied by the control unit, and is configured such that power is applied together with the operation of the curtain airbag 1 in a vehicle crash.

본 발명에 의한 자성체(110)는 분말 형태의 철가루인 것을 특징으로 한다.Magnetic body 110 according to the present invention is characterized in that the powder of iron powder.

상기 자성체(110)가 설치된 에어쿠션(2)의 접착부(100)는 에어쿠션(2)의 두께에 비해 상대적으로 적은 두께를 유지하도록 구성된다.The adhesive part 100 of the air cushion 2 in which the magnetic body 110 is installed is configured to maintain a relatively small thickness compared to the thickness of the air cushion 2.

이와 같이 구성되는 본 발명에 의한 차량용 커튼에어백의 작동 상태를 도면을 참조하여 설명한다.The operation state of the vehicular curtain airbag according to the present invention configured as described above will be described with reference to the drawings.

첨부된 도 4를 참조하면, 차량에 운전자가 탑승한 상태에서 도로를 따라 차량 주행이 이루어지다가 상기한 차량이 전복되거나 측면에 충돌되는 사고가 발생되 면서 상기한 차량에 설치된 감지센서가 충격을 감지한다.Referring to FIG. 4, while the vehicle is driven along the road while the driver is in the vehicle, an accident in which the vehicle is overturned or a collision occurs on the side of the vehicle detects an impact. .

상기한 감지센서는 감지한 충격 신호를 제어부에 전송하고, 상기한 제어부는 이를 연산하여 차량에 설치된 커튼에어백(1)이 작동 가능한지를 연산하고, 커튼에어백(1)의 작동이 필요할 경우에는 인플레이터에 제어 신호를 전송한다.The detection sensor transmits the detected shock signal to the control unit, and the control unit calculates this to calculate whether the curtain airbag 1 installed in the vehicle is operable, and if necessary to operate the curtain airbag 1 to the inflator. Send a control signal.

인플레이터는 제어부의 제어 신호에 의해 고압의 인플레이터 가스를 커튼에어백(1)에 구비된 에어쿠션(2)의 내부 영역으로 공급하여 상기한 커튼에어백(1)을 전개시켜 운전자를 보호하되,The inflator supplies the high pressure inflator gas to the inner region of the air cushion 2 provided in the curtain airbag 1 according to the control signal of the controller to expand the curtain airbag 1 to protect the driver.

차량 전복 사고가 발생될 경우에는 차량에 탑승한 운전자의 머리가 차량 외측으로 이탈될 수 있으므로 본 발명에 의한 자력부(200)에 전원이 인가되어 차 실내를 향해 하향 작동되는 에어쿠션(2)이 이동되면서 상기한 자력부(200)에 접착부(100)가 자화되면서 밀착이 이루어지게 된다.When the vehicle overturning accident occurs, the head of the driver in the vehicle may be separated out of the vehicle, the air cushion 2 is applied to the magnetic force unit 200 according to the present invention and operated downward toward the interior of the vehicle. As the adhesive part 100 is magnetized to the magnetic force part 200 while being moved, a close contact is made.

본 발명에 의한 접착부(100)의 자성체(110)는 분말 형태의 철가루로 이루어저 있어서 도면에 도시된 바와 같이 에어쿠션(2)의 하단부가 도어 크림(3)에 밀착되게 된다.The magnetic body 110 of the adhesive portion 100 according to the present invention is made of iron powder in the form of powder so that the lower end of the air cushion 2 is in close contact with the door cream 3.

따라서, 이와 같이 작동되는 에어쿠션(2)에 의해 탑승자의 머리 부분이 보호되고, 외부에서 별도의 이물질 침입이 방지된다.Thus, the head of the occupant is protected by the air cushion 2 operated as described above, and separate foreign matter from the outside is prevented.

자력부(200)에 인가되는 전원은 제어부에 의해 일정시간동안 유지되며, 이와 같이 작동되는 에어쿠션(2)에 의해 탑승객의 상해가 저감된다.Power applied to the magnetic force unit 200 is maintained by the control unit for a predetermined time, the injury of the occupants is reduced by the air cushion (2) operated in this way.

이상에서는 본 발명의 바람직한 실시예에 대하여 도시하고 또한 설명하였으나, 본 발명은 상기한 실시예에 한정되지 않으며, 특허청구범위에서 청구된 본 발 명의 요지를 벗어남이 없이 당해 본 발명이 속하는 기술분야에서 통상의 지식을 가진 자라면 누구든지 다양한 변형 실시가 가능한 것은 물론이고, 그와 같은 변경은 기재된 청구범위 내에 있게 된다.Although the above has been illustrated and described with respect to the preferred embodiments of the present invention, the present invention is not limited to the above-described embodiments, but in the art to which the present invention pertains without departing from the spirit of the invention as claimed in the claims. Various modifications can be made by those skilled in the art, and such changes will fall within the scope of the claims set forth.
