일반적으로 자동차는 주행성과 더불어 안전성을 고려하여 차량의 실내에 에어 백을 많이 장착하고 있다.In general, automobiles are equipped with a lot of airbags in the interior of the vehicle in consideration of driving safety.
이러한 에어 백은 스티어링 휠의 중앙과 크래쉬 패드의 좌측, 그리고 앞좌석 등받이의 뒷면에 각각 하나씩 4개가 설치되며, 이렇게 설치된 에어 백은 차량의 전방에 설치된 감지센서가 충격에 대한 입력신호를 전자제어유니트에 제공하게 되면 이 전자에어유니트의 제어에 의하여 선택적으로 전개된다.Four airbags are installed in the center of the steering wheel, the left side of the crash pad, and the back of the front seat back, respectively, and the airbags installed in this way are electronically controlled by the sensor installed in front of the vehicle. When provided to, it is selectively developed under the control of this electronic air unit.
그러나, 기존의 에어 백은 차량의 추돌/충돌 사고 발생으로 충격감지센서가 일정한 충격량 이상을 감지하게 되면 작동하도록 회로가 구성되어 있어서, 어린이가 탑승한 경우 이 에어 백이 전개로 상해를 입는 경우가 종종 발생하게 되어, 이에 대한 개선이 필요하게 되었다.However, the existing airbag is configured to operate when the impact sensor detects a certain amount of impact due to a collision / collision of the vehicle, so that the airbag is often injured when deployed by a child. This has occurred, and there is a need for improvement.
본 고안은 상기와 같은 점을 감안하여 안출한 것으로, 웨빙 리트렉터의 내부에 설치되어 웨빙이 권취된 스풀에 감지수단을 설치하고, 이 감지수단이 풀려진 웨빙의 길이에 대한 입력신호를 전자제어유니트에 제공하여서, 에어 백이 그 길이에 비례하여 전개가능하게 함으로써, 탑승자가 어린이와 같이 체형이 작은 경우 에어 백이 전개되는 압력을 약하게 하여서, 에어 백의 전개되면서 발생하는 신체적 상해를 미연에 방지할 수 있도록 한 자동차의 에어 백 전개를 제어하는 장치를 제공하는데 그 목적이 있다.The present invention has been devised in view of the above, and is provided inside the webbing retractor and installs a sensing means in a spool in which webbing is wound, and electronically controls an input signal for the length of the webbing in which the sensing means is released. Provided with the unit, the air bag can be deployed in proportion to its length, thereby reducing the pressure that the air bag deploys when the occupant is small, such as a child, so as to prevent physical injuries occurring when the air bag is deployed. It is an object of the present invention to provide a device for controlling the deployment of an air bag in a vehicle.

이하, 첨부도면을 참조하여 본 고안의 구성에 대하여 살펴보면 다음과 같다.Hereinafter, the configuration of the present invention with reference to the accompanying drawings.
본 고안은 웨빙 리트렉터(10)를 포함하는 자동차의 에어 백 전개를 제어하는 장치에 있어서, 상기 웨빙 리트렉터(10)는 그 내부에 웨빙(12)이 권취된 스풀(11)의 회전량을 감지가능한 감지수단이 구비되어 있되, 상기 감지수단은 발광다이오드(13)와 포토다이오드(14)로 이루어져서, 전자제어유니트(20)의 입력신호를 제공하여 상기 웨빙(12)의 길이에 비례로 에어 백이 전개가능하도록 한 것을 특징으로 한다.The present invention is a device for controlling the air bag deployment of a vehicle including a webbing retractor (10), the webbing retractor (10) is the amount of rotation of the spool (11) in which the webbing (12) is wound therein A sensing means is provided, wherein the sensing means comprises a light emitting diode 13 and a photodiode 14 to provide an input signal of the electronic control unit 20 to provide air in proportion to the length of the webbing 12. The bag is made deployable.
이를 첨부도면을 참조하여 보다 상세하게 설명하면 다음과 같다.This will be described in more detail with reference to the accompanying drawings.
첨부도면 1은 본 고안에 따른 시트 벨트의 요부를 개략적으로 나타낸 측면도로서, 도면부호 10은 웨빙 리트렉터를, 20은 전자제어유니트를 각각 나타낸다.1 is a side view schematically showing the main part of the seat belt according to the present invention, wherein 10 is a webbing retractor and 20 is an electronic control unit, respectively.
본 고안은 상기 웨빙 리트렉터(10)의 내부에 웨빙(12)이 일정길이만큼 탄성지지를 받아 권취된 스풀(11)의 회전량을 감지할 수 있도록 감지수단을 설치하고, 이 감지수단이 시트 벨트를 착용함에 따라 착용길이를 감지하여 상기 전자제어유니트(20)에 제공함으로써, 상기 전자제어유니트(20)가 웨빙(12)의 길이와는 비례로 에어 백을 전개시킬 수 있도록 한 것이다.The present invention is installed in the webbing retractor 10, the sensing means to detect the rotation amount of the spool 11 wound by the webbing 12 is elastically supported by a predetermined length, the detection means is a seat The wearing length of the belt is detected and provided to the electronic control unit 20 so that the electronic control unit 20 can deploy the air bag in proportion to the length of the webbing 12.
여기서, 상기 감지수단은 스풀(11)의 회전궤적과 일부 구간이 겁쳐지도록 설치된 발광다이오드(13)와 포토다이오드(14)로 구성되어 있으며, 이때 상기 스풀(11)은 그 외주면에 기어부와 같이 요홈(15)이 연속하여 반복형성하여 상기 감지수단이 스풀(11)의 회전량을 용이하게 파악할 수 있도록 유도하게 된다.Here, the sensing means is composed of a light emitting diode 13 and a photodiode 14 installed so as to scare the rotational trajectory and some sections of the spool 11, wherein the spool 11 is like the gear portion on the outer peripheral surface The groove 15 is continuously formed repeatedly so that the sensing means can easily grasp the amount of rotation of the spool 11.
따라서, 상기 시트에 착좌한 탑승자의 신체적 조건에 따라 웨빙(12)의 길이가 달라지는 경우, 예를 들면 어린이가 탑승하게 되면 웨빙(12)의 길이가 짧아지기 때문에 이에 비례하여 에어 백이 전개되는 정도를 줄일 수 있게 되는 것이다.Therefore, when the length of the webbing 12 is changed according to the physical condition of the occupant seated on the seat, for example, the length of the webbing 12 is shortened when a child rides, so that the degree of the air bag is deployed in proportion thereto. It will be reduced.
이상에서 본 바와 같이 본 고안은 웨빙 리트렉터의 내부에 스풀이 회전량을 감지하여 풀려진 웨빙의 길이를 알 수 있도록 감지수단을 설치하고, 이 감지수단의 입력신호를 받은 전자제어유니트는 웨빙의 길이에 비례하여 에어 백의 전개되는 정도를 조절할 수 있게 함으로써, 어린이가 탑승한 경우 에어 백의 전개되는 압력을 줄여, 신체가 상해를 입게 되는 것을 사전에 막아 안전성을 높여 주게 되는 효과가 있다.As seen from the above, the present invention installs a sensing means in the inside of the webbing retractor so as to know the length of the released webbing by detecting the amount of rotation of the spool, and the electronic control unit receiving the input signal of the sensing means By being able to adjust the degree of deployment of the airbag in proportion to the length, it is effective in reducing the pressure of the deployment of the airbag when a child rides, preventing the body from being injured in advance, thereby increasing safety.
