Description

자동차 뒷좌석용 에어백Car Back Seat Air Bag

본 고안은 자동차의 에어백에 관한 것으로, 구체적으로는 탑승자의 뒷좌석 승차여부를 판단하는 판단수단을 구비하고 차량 루프 중앙부에 에어백을 장착하여 충격신호와 탑승감지 신호에 의해서만 에어백이 루프로부터 하방으로 전개되도록 하는 뒷좌석용 에어백에 관한 것이다.The present invention relates to an airbag of a vehicle, and in particular, has a determining means for determining whether the occupant is in the rear seat, and the airbag is mounted at the center of the vehicle roof so that the airbag is deployed downward from the roof only by the impact signal and the boarding detection signal. It relates to a rear seat airbag.

일반적으로 자동차에 장착된 에어백은 주행 도중의 자동차가 충돌이나 기타의 돌발적인 사고로 충격력을 받으면 이 충격력에 따라 고압의 가스가 에어백에 급속히 충진되도록 하여 전개 팽창되는 에어백이 탑승자의 신체를 충격력으로부터 보호할 수 있도록 하고 있다.In general, an airbag mounted on a vehicle is provided with a high-pressure gas rapidly filled in the airbag according to the impact force when the vehicle is impacted by a collision or other accident while driving. I can do it.

이러한 에어백은 신속하게 전개됨은 물론 탑승자의 전신을 보호할 수 있는 구조를 취하도록 하고, 또 가스를 급속히 발생시키는 가스 발생기는 고온 고압의 가스와 함께 찌꺼기를 발생하기 때문에 이를 여과 시킬 수 있는 필터를 장착하고 있으며, 차량의 경량화 추세에 따라 경량의 구조로 이루어지도록 하고 있다.Such airbags can be deployed quickly and have a structure that can protect the entire body of the occupant, and a gas generator that generates gas rapidly generates debris together with high-temperature, high-pressure gas, and is equipped with a filter that can filter them. And, according to the trend of light weight of the vehicle is to be made of a lightweight structure.

상기한 바와 같은 에어백은 일반적으로는 자동차의 스티어링 휠에 전개 가능하도록 장착되어 자동차의 전후방 충돌로 인하여 관성에 따라 탑승자가 전방으로부터의 부딪힘을 받쳐주어 탑승자의 신체를 보호할 수 있도록 하고 있다.The airbag as described above is generally mounted to be deployed on the steering wheel of the vehicle to protect the occupant's body by supporting the occupant from the front due to the inertia due to the front and rear collision of the vehicle.

또한, 차량의 뒷좌석에 승차한 탑승자를 보호하기 위하여 장착된 에어백은 도 5 및 도 6 에 도시한 바와 같이 차량의 앞 시트(3) 뒷부분에 장착되어 충돌시 전개되도록 구성하고 있으나, 이와 같은 경우에는 에어백(1)이 전개되더라도 양 시트(3) 사이의 중앙부는 공간(31)이 비게되어 어린이 등 체구가 작은 탑승자의 경우에는 양 시트(3) 중앙부 공간(31)을 통하여 전방으로 이탈되는 위험이 있으며, 에어백(1)의 팽창으로 인한 반발력으로 탑승자가 피해를 당하는 문제점이 보고된 바 있다.In addition, the airbag mounted to protect the occupant in the rear seat of the vehicle is mounted on the rear part of the front seat 3 of the vehicle as shown in Figs. Even if the airbag 1 is deployed, the center 31 between the two seats 3 is empty, so that in the case of a small passenger, such as a child, there is a risk of being separated forward through the center space 31 of both seats 3. In addition, a problem has been reported that the occupant is damaged by the repulsive force due to the expansion of the airbag (1).

본 고안은 상기와 같은 종래의 에어백의 문제점을 보완하기 위한 것으로, 자동차의 에어백에 있어서, 차량의 뒷좌석(2)에 장착하여 하중을 감지하여 승차 여부를 감지하는 승원 감지센서(10)와, 차량의 전방부에 장착되어 차량의 충돌을 감지하는 충돌 감지센서(20)와, 루프(4) 중앙부에 장착되며 상기 승원 감지센서(10)와 충돌 감지센서(20)의 신호에 의하여 하방으로 전개되는 천정 부착형 에어백(30)으로 구성되어지는 것을 특징으로 하는 것이다.The present invention is to compensate for the problems of the conventional air bag as described above, in the airbag of the vehicle, mounted on the rear seat (2) of the vehicle to detect the load by detecting the occupancy of the occupant and the vehicle, Collision detection sensor 20 is mounted to the front of the collision detection sensor 20 for detecting a collision of the vehicle, and is mounted in the central portion of the loop (4) is deployed downward by the signal of the occupant detection sensor 10 and the collision detection sensor 20 It is characterized by consisting of a ceiling-mounted airbag (30).

이하 본 고안을 첨부도면을 참조하여 상세히 설명하면 다음과 같다.Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

도 1 은 본 고안의 뒷좌석용 에어백의 장착 위치도로서, 도시한 바와 같이 본 고안의 에어백은 승원 감지센서(10), 충돌 감지센서(20) 및 천정 부착형 에어백(30)으로 구성되어진다.1 is a mounting position of the rear seat airbag of the present invention, as shown, the airbag of the present invention is composed of a passenger sensor 10, the collision detection sensor 20 and the ceiling-mounted airbag (30).

상기 승원 감지센서(10)는 차량의 뒷좌석(2) 내부에 장착되어 하중을 감지하여 탑승자의 승차여부를 추정하는 것으로 센서(10)의 감지량이 일정하중 이상이면 충돌 감지센서(20)로 제어 신호를 신호를 입력하고 일정하중 이하이면 제어신호를 발생하지 않도록 구성되어 진다.The occupant detection sensor 10 is mounted inside the rear seat 2 of the vehicle to detect a load and estimate whether the occupant is riding. If the amount of detection of the sensor 10 is equal to or greater than a predetermined load, the control signal is transmitted to the collision detection sensor 20. It is configured not to generate a control signal when inputting a signal and below a certain load.

상기 충돌 감지센서(20)는 차량의 전방에 장착되는 것으로 차량의 충돌사고 등에 의하여 차량에 가해지는 충격량을 감지하여 루프(4) 중앙부에 장착된 에어백 유니트(30)에 작동신호를 입력하는 것이다.The collision sensor 20 is mounted at the front of the vehicle and detects an impact amount applied to the vehicle by a collision accident of the vehicle and inputs an operation signal to the airbag unit 30 mounted at the center of the loop 4.

상기 천정 부착형 에어백(30)은 차량 루프(4)의 중앙부에 장착되어지며, 헤드 라이닝(head-lining)을 포함하여 구성하거나 혹은 별도로 구성되는 것으로, 승원 감지센서(10)의 신호와 충돌 감지센서(20)의 두 센서(10,20)의 신호를 입력 받아 에어백(1)을 하방으로 전개되어 지도록 구성하는 것이다.The ceiling-mounted airbag 30 is mounted at the center of the vehicle roof 4 and includes a head-lining or is configured separately, and detects a collision with a signal of the occupant detecting sensor 10. The airbag 1 is configured to be deployed downward by receiving signals from the two sensors 10 and 20 of the sensor 20.

도 2 와 도 3 은 에어백 전개시의 측면도와 배면도를 개략적으로 도시한 것으로, 차량의 승원 감지센서(10)와 충돌 감지센서(20)의 제어신호가 입력되면 루프(4) 천정으로 부터 하방으로 전개되는 것으로, 에어백(1)이 완전히 전개되어지면 도 3 에 도시한 바와 같이 앞좌석(3)의 공간부(31)를 완전히 커버할 수 있어 뒷좌석(2)에 승차한 탑승자가 좌석(3)의 앞쪽으로 이탈되어지는 것을 보호하는 것이다.2 and 3 schematically illustrate a side view and a rear view when the airbag is deployed, and when the control signals of the occupant sensor 10 and the collision sensor 20 of the vehicle are input, are lowered from the ceiling of the roof 4. When the airbag 1 is fully deployed, the airbag 1 can fully cover the space 31 of the front seat 3, as shown in FIG. Is to protect it from going forward.

도 4 는 본 고안의 에어백 작동 순서도로서, 먼저 승원 감지센서(10)에 의하여 하중을 감지하여 뒷좌석의 탑승자 존재여부를 판단하는 제 1 단계(101);FIG. 4 is a flowchart illustrating an operation of the airbag according to the present invention. First, a first step 101 of detecting a presence of a occupant in the rear seat by detecting a load by an occupant detecting sensor 10;

차량의 전방부에 장착된 센서(20)에 의하여 차량의 충돌 여부를 판단하는 제 2 단계(201);A second step 201 of determining whether or not the vehicle is collided by the sensor 20 mounted at the front of the vehicle;

제 1 단계(101) 및 제 2 단계(201)에 의하여 차량의 승원 및 충돌이 감지되면 에어백(1)이 차량의 루프(4)로 부터 하방으로 전개되어지는 제 3 단계(301)로 구성되어진다.When the occupancy and collision of the vehicle is detected by the first stage 101 and the second stage 201, the airbag 1 is configured as a third stage 301 which is deployed downward from the roof 4 of the vehicle. Lose.

상술한 바와 같은 본 고안의 자동차 뒷좌석용 에어백은 충돌사고시 뒷좌석 탑승 승객을 효과적으로 보호 할 수 있으며, 뒷좌석에 탑승자가 있을 경우에만 에어백이 작동되므로 종래와 같은 후방 전개시의 반발력에 의한 승원의 피해를 줄일 수 있는 효과는 물론 앞 시트 보다 상대적으로 저렴한 헤드 라이닝 또는 에어백 유니트 만의 교환이 가능해 운전자의 재산상의 손실을 줄일 수 있는 효과가 있는 것이다.As described above, the airbag for the rear seat of the present invention can effectively protect the passengers in the rear seats in the event of a crash, and the airbags operate only when there are occupants in the rear seats, thereby reducing the damage of the occupants due to the repulsive force in the conventional rear deployment. In addition, the replacement of the head lining or the airbag unit, which is relatively cheaper than the front seats, is possible, thereby reducing the driver's property loss.

본 고안의 목적은 첫째; 차량의 뒷좌석의 에어백을 루프에서 전개되도록하여 충돌시 앞 시트의 중앙부 공간을 커버하도록 하여 뒷좌석 탑승자를 보호할 수 있도록 하는 것이며, 둘째; 센서에 의해 뒷좌석 탑승자를 감지하여 탑승시에만 에어백이 전개되도록 구성하여 후방으로 팽창되는 반발력을 억제할 수 있도록 하는 자동차 뒷좌석용 에어백을 제공하는 것이다.The purpose of the present invention is first; The airbags of the rear seats of the vehicle are deployed in the roof so that the rear seat occupants can be protected by covering the center space of the front seat in the event of a collision; It is to provide an airbag for the rear seat of the car to detect the rear seat occupant by the sensor so that the airbag is deployed only during the boarding to suppress the repulsive force inflated to the rear.
