Description
본 발명은 에어 백에 관한 것이고, 보다 상세하게는 탑승자의 체형을 감지하여, 체형이 작은 탑승자의 경우에 자동차의 시트가 리프팅되어 에어 백에 의하여 보호될 수 있는 리프팅 시트를 이용한 에어 백 제어 방법에 관한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an air bag, and more particularly, to an air bag control method using a lifting seat capable of sensing the occupant's body shape and protecting a seat of an automobile when the occupant is a small- .
통상적으로, 자동차의 에어 백은 자동차 전방에서의 충돌시 전방 시트에 탑승한 운전자와 조수석에 탑승한 사람을 보호하기 위하여 자동차의 조향 핸들과 자동차의 인스트루먼트 패널에 설치되는 콘솔 박스에 장착된다. 자동차 전방에 대한 충돌시 충돌 감지 센서가 자동차의 충돌을 감지하여, 감지된 충돌 신호를 전자 제어 장치로 보내면, 전자 제어 장치는 에어 백 모듈에 전류를 공급하여, 자동차에 설치된 에어 백을 작동시킨다.BACKGROUND OF THE INVENTION [0002] Conventionally, an air bag of an automobile is mounted on a steering wheel of a car and a console box installed in an instrument panel of an automobile in order to protect a driver who rides on a front seat and a passenger in a passenger seat in a collision in front of the automobile. In the event of a collision against the front of the automobile, the collision detection sensor senses the collision of the vehicle and sends the detected collision signal to the electronic control unit, which supplies current to the airbag module to operate the airbag installed in the vehicle.
따라서, 자동차의 조향 핸들과 자동차의 인스트루먼트 패널에 설치되는 콘솔 박스에 장착된 에어 백은 자동차의 충돌시 운전석 및 조수석에 탑승한 승객이 안전 벨트의 착용에도 불구하고, 자동차의 주행에 따른 관성에 의하여 자동차의 전방부에 부딪쳐 발생할 수 있는 상해의 정도를 감소시켜 승객을 보호한다.Therefore, the airbag mounted on the steering wheel of the vehicle and the console box installed on the instrument panel of the automobile is not affected by the inertia due to the running of the vehicle, despite the wearing of the seatbelt in the driver's seat and the passenger's seat, It protects the passengers by reducing the degree of injury that may occur in the front part of the car.
자동차에 5명 이상이 탑승한 경우, 종래의 에어 백은 상기된 바와 같이 자동차의 조향 핸들과 인스트루먼트 패널에 설치되는 콘솔 박스에 장착되므로, 후방 시트의 중앙에 탑승한 사람이 안전 벨트를 착용하고 있지 않을 때, 전방 시트의 운전석과 조수석이 서로 분리되어 있기 때문에, 후방 시트의 중앙에 탑승한 사람은 자동차의 충돌시 자동차의 관성에 의하여 전방 시트 사이로 퉁겨 나가 자동차의 전방 유리와 머리가 충돌하여, 생명에 치명적인 영향을 줄 수 있는 상해를 당하거나 사망하게 될 수 있다.In the case where more than five persons are aboard the automobile, the conventional airbag is mounted on the steering wheel of the automobile and the console box installed on the instrument panel as described above, so that the person who rides in the center of the rear seat wears the seatbelt The driver and the passenger seat of the front seat are separated from each other. Therefore, a person who rides in the center of the rear seat collides with the front seat between the front seats due to inertia of the vehicle when the vehicle collides, You may be injured or killed.
특히, 어린이를 동반하는 경우에, 자동차의 후방 시트는 어린이가 탑승하는 경우가 많고, 어린이의 경우 안전 벨트를 착용하지 않는 일이 많기 때문에, 자동차의 충돌시 후방 시트 중앙에 탑승한 어린이의 안전 문제는 더욱 심각하게 된다.Particularly, in the case of accompanying a child, since the rear seat of a vehicle is often carried by a child and a child does not often wear a seatbelt, a safety problem of a child who rides in the center of the rear seat Becomes more serious.
한편, 근래에 들어 자동차의 운전석 외에도 조수석에도 에어 백이 장착되는 경우가 많으며, 상기와 같은 이유 때문에, 탑승 인원이 5명 이하이고 어린이의 연령이 자기의 몸을 지탱할 수 있는 경우, 어린이를 에어 백이 장착된 조수석에 탑승시키는 경우가 있다.On the other hand, in recent years, airbags are often mounted on passenger seats in addition to the driver's seat of automobiles. For the above reasons, when the number of passengers is less than 5 and the age of the child can support the self body, Passengers may be boarded in the passenger seat.
그러나, 조수석에 장착되는 에어 백은 조수석의 전방에 위치되는 인스트루먼트 패널에 설치되며, 에어 백은 작동시에 어른의 가슴 부위에 작동되도록 설치되어, 어린이의 체형이 어른의 체형 보다 작으므로, 에어 백이 작동할 때, 에어 백이 조수석에 탑승한 어린이의 머리 또는 머리 위로 작동되며, 에어 백은 320km/h의 속도로 작동하기 때문에, 가슴 부위가 아닌 머리에 에어 백이 작동되는 것에 의한 어린이가 에어 백의 작동 충격에 의하여 심한 상해를 당할 수 있다는 문제점이 있었다.However, the airbag mounted on the passenger seat is installed in an instrument panel located in front of the passenger seat. Since the airbag is installed to operate on the chest area of an adult during operation, the child's body shape is smaller than that of an adult, In operation, the airbag is operated on the head or head of a child aboard the passenger seat, and the airbag operates at a speed of 320 km / h, so that when the airbag is actuated on the head, There is a problem in that it can be seriously injured.
따라서, 본 발명의 목적은 조수석에 탑승한 어린이의 가슴 부위에 에어 백이 작동될 수 있도록 에어 백의 작동과 동시에 조수석이 리프팅되어, 조수석에 탑승한 어린이를 보호할 수 있는 리프팅 시트를 이용한 에어 백 제어 방법을 제공하는 데 있다.SUMMARY OF THE INVENTION Accordingly, it is an object of the present invention to provide an air bag control method using a lifting seat capable of protecting a child aboard a passenger seat by lifting a passenger seat simultaneously with the operation of the air bag so that the air bag can be operated on a chest area of a child aboard the passenger seat .

[실시예][Example]
이하, 명세서에 첨부된 도면을 참조하여 본 발명의 바람직한 실시예를 보다 상세하게 설명한다.Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the drawings attached hereto.
도 1은 본 발명에 따른 리프팅 시트를 이용한 에어 백 제어 방법을 실행하기 위한 흐름도이다. 도 1로부터, 본 발명에 따른 리프팅 시트를 이용한 에어 백 제어 방법을 구체적으로 설명하면, 조수석의 안전 벨트의 착용 여부를 감지하여(ST1), 안전 벨트를 착용하였을 때, 도 2, 도 3, 및 도 4에 도시된 바와 같이, 인스트루먼트 패널(1)에 설치된 적외선 감지 센서(2)를 작동시켜(ST2), 조수석(3)의 탑승자의 체형을 체크하는 한다(ST3).1 is a flowchart for executing an air bag control method using a lifting sheet according to the present invention. 1, a method of controlling an air bag using a lifting sheet according to the present invention will be described in detail. First, it is detected whether a passenger seat is worn (ST1). When a seat belt is worn, The infrared sensor 2 installed in the instrument panel 1 is operated (ST2) to check the body shape of the occupant of the passenger seat 3 (ST3), as shown in Fig.
ST3 단계에서, 적외선 감지 센서(2)에 의하여 감지된 조수석(3)에 탑승한 탑승자의 체형(P)은 ECU에 입력된 각도(B)의 범위와 비교되고(ST4), 탑승자의 체형(P)이 각도(B)와 P⊂B의 관계이면, 자동차에 설치된 ECU는 조수석(3) 리프팅 기구를 작동시키는 것에 의하여 탑승자가 각도 B의 범위의 범위에 놓이도록 조수석(3)이 다수의 단계, 바람직하게는 10개의 단계 중에서 1단계로 리프팅 되고(ST5), ST4의 단계를 반복적으로 수행하여, 바람직하게는 10개의 단계별로 일정 높이로 리프팅시킨다(ST5 내지 ST8). 한편, ST5 단계에서, 에어 백 시스템은 온 상태로된다(ST10). 이 때, 조수석(3)의 리프팅 단계에서, 조수석(3)이 최대의 높이로 리프팅되더라도, 탑승자가 각도(B)의 범위에 놓일 때, 에어 백 시스템은 오프되고(ST9), 경고등이 점등하여 사용자가 인식되도록 한다. 따라서, 도 4에 도시된 바와 같이, 어린이와 같이 체형이 작은 탑승자가 각도 범위(B)에 놓이게 된다.The body shape P of the occupant aboard the passenger seat 3 sensed by the infrared ray sensor 2 is compared with the range of the angle B input to the ECU in ST3, The ECU installed in the vehicle is operated in a plurality of steps such that the passenger 3 is in the range of the angle B by operating the lifting mechanism of the front passenger seat 3, Preferably, one of the ten steps is lifted to one step (ST5), and the step of ST4 is repeatedly performed, preferably lifted to a predetermined height by ten steps (ST5 to ST8). On the other hand, in ST5, the air bag system is turned on (ST10). At this time, even if the passenger seat 3 is lifted to the maximum height in the lifting step of the front passenger seat 3, when the occupant is in the range of the angle B, the air bag system is turned off (ST9) Let the user be recognized. Therefore, as shown in Fig. 4, a passenger with a small body, such as a child, is placed in the angular range B.
한편, 도 2에 도시된 바와 같이, 감지 각도(B)는 조수석(3)이 접혀지는 각도(A)반비례하고, 또한 조수석(3)의 전후 이동 거리(L)과도 반비례하여 다음과 같은 관계가 성립된다:2, the sensing angle B is inversely proportional to the angle A at which the passenger seat 3 is folded, and inversely proportional to the back-and-forth travel distance L of the front passenger seat 3, Established:
A ∝ 1/B ∝ L.A? 1 / B? L.
즉, A = 1/(B+C) · 1/B = L + D,That is, A = 1 / (B + C) 1 / B = L + D,
고로, B = C/( L +D - A)의 관계가 성립된다. 상기에서, L,C,D는 상수이다.Therefore, the relationship of B = C / (L + D - A) is established. In the above, L, C, and D are constants.
상기된 바와 같이, 본 발명에 따른 리프팅 시트를 이용한 에어 백 제어 방법에 의하면, 에어 백이 장착된 조수석에 어린이 또는 체형이 작은 사람이 탑승한 경우에도, 에어 백이 가슴 부위에 작동하여 에어 백의 작동으로 인한 제 2 차 사고를 방지하여, 탑승자의 체형에 따른 에어 백에 의한 상해를 방지할 수 있다.As described above, according to the airbag control method using the lifting sheet according to the present invention, even when a child or a person with a small body is aboard the passenger seat equipped with the airbag, the airbag operates on the chest area, It is possible to prevent the second accident and to prevent the injury caused by the airbag according to the body shape of the occupant.
