Description

자동차와 비행기용 상반신 에어백 장치{Airbag system for automobile and airplane}Airbag system for automobile and airplane

본 발명은 자동차나 비행기의 탑승자를 보호하기 위해 사용되는 상반신 에어백 장치에 관한 것으로, 자동차나 비행기에 장착된 시트의 양측에 각각 상반신을 감싸는 형태의 에어백이 접혀져 수납되어, 충돌 등의 사고 발생시 상기 각각의 에어백이 상반신의 좌우측의 반반씩을 감싸도록 내측이 오목한 형상으로 펼쳐짐으로써, 사고시 가장 치명적인 머리 등을 포함한 상반신을 효과적으로 보호함으로써 각종 사고로부터 인명 피해를 줄일 수 있는 자동차와 비행기용 상반신 에어백 장치에 관한 것이다.The present invention relates to an upper body airbag device used to protect occupants of an automobile or an airplane, wherein airbags each having a form surrounding the upper body are folded and stored on both sides of a seat mounted on an automobile or an airplane, respectively, when an accident such as a collision occurs. It is related to the upper body airbag device for automobiles and airplanes which can reduce the human injury from various accidents by effectively protecting the upper body including the most fatal head in case of accident by spreading the inside of the upper half of the upper and lower half of the upper body. .

자동차나 비행기에 설치된 에어백은 충돌 등의 사고시 운전자 및 승객들을 보호하기 위하여 설치되는 것으로, 주로 핸들, 데시보드, 도어의 내측 등 승객과 가까운 곳에 장착된 수납함에 에어백이 접혀 수납되고, 사고 발생시 감지센서가 감지하여 작동기체 발생장치를 작동시키는 구조를 가진다. 즉 감지센서에 의해 충돌 이 감지되면 작동기체 발생장치가 폭발되고, 폭발가스가 가스공급관을 따라 에어백으로 이동되어 순간적으로 에어백이 부풀어 오르면서 수납함의 외부로 튀어나오게 된다.Airbags installed in cars or airplanes are installed to protect drivers and passengers in the event of an accident. Airbags are folded and stored in a box mounted near the passengers such as a handle, a dashboard and the inside of a door. Has a structure to detect and operate the working gas generator. That is, when a collision is detected by the sensor, the working gas generator is exploded, and the explosive gas is moved to the airbag along the gas supply pipe, and the airbag inflates instantly and pops out of the storage box.

이와 같은 종래의 에어백은 주로 운전대나 데쉬보드 또는 도어의 내측 등에서 부풀어 올라 운전자나 승객이 기물과 부딪쳐 받게 되는 충격을 완화시키는 구조이다. 특히 에어백의 구조를 보면, 운전대에 장착된 경우는 둥근 원형으로 부풀어 오르는 구조이고, 데쉬보드나 도어 등에 설치되는 경우는 넓은 매트와 같이 펼쳐지는 구조이다. 따라서 이와 같은 에어백은 운전자나 승객이 충돌에 의해 순간 이동되어 차체에 부딪힐 때의 충격을 완화시켜 주는 역할을 하도록 하고 있다.Such a conventional airbag is a structure that mitigates the impact that the driver or passenger is bumped into the object mainly by inflating the steering wheel, the dashboard or the inside of the door. In particular, the structure of the airbag, when mounted on the steering wheel is a rounded swelling structure, and when installed on the dashboard or door, such as a wide mat unfolding structure. Therefore, such an airbag is intended to mitigate the impact when a driver or passenger is momentarily moved by a collision and hits the vehicle body.

상기와 같은 종래의 에어백 장치는 승객이 사고로 인한 충격으로 운전대 방향으로 튕겨져 충돌할 때 그 충격을 완화시켜 주는 정도에 그치고, 상체의 급격한 움직임은 안전벨트가 방지하게 된다. 안전벨트를 착용하더라도 상반신의 급격한 움직임을 방지할 수 없어 운전대 등의 에어백이 필수적이라 할 수 있다.The conventional airbag device as described above is only to mitigate the impact when the passenger is bounced toward the steering wheel due to the impact of the accident, and the sudden movement of the upper body is prevented by the seat belt. Even if a seat belt is worn, a sudden movement of the upper body cannot prevent the airbag such as a steering wheel.

따라서 종래의 경우는 상반신을 안전벨트에만 의지하는 구조이고, 사고의 발생시 가장 치명적인 손상은 머리를 비롯한 상반신에서 일어나게 된다.Therefore, in the conventional case, the upper body is structured to rely only on the seat belt, and in the event of an accident, the most fatal damage occurs in the upper body including the head.

이와 같이 본 발명은 안전벨트와 같이 상반신의 급격한 움직을 방지함과 동시에 상반신에 가해지는 충돌로부터 충격을 방지하기 위하여 상반신을 감싸도록 에어백 장치를 제공함에 목적이 있다.Thus, an object of the present invention is to provide an airbag device to wrap the upper body to prevent the sudden movement of the upper body like the seat belt and to prevent the impact from the collision applied to the upper body.

상기와 같은 에어백을 제공하기 위하여, 상반신을 감쌀 수 있는 위치인 시트의 상부의 좌우측에 각각 에어백을 설치하고, 팽창되어 펼쳐졌을 때 각각의 에어백이 상반신의 좌우측을 감싸도록 하는 구조를 가진다.In order to provide the airbags as described above, airbags are respectively installed on the left and right sides of the upper part of the upper body to which the upper body can be wrapped, and when inflated and deployed, each airbag surrounds the left and right sides of the upper body.

상기와 같이 시트의 상부 양측에 각각 설치된 에어백이 충동시 팽창하게 되면, 승객의 상반신 전방에서 펼쳐져 에어백과 시트의 등받이 사이에 승객을 에워싸 게 되어, 가장 치명적인 손상을 입는 상반신을 효과적으로 보호함으로써 교통사고로부터 인명을 보호할 수 있게 된다.As described above, when the airbags respectively installed on the upper both sides of the seat are inflated at the time of impulse, the airbag is deployed in front of the upper body of the passenger and surrounds the passenger between the back of the airbag and the seat, effectively protecting the most deadly upper body of the traffic accident. It can protect lives.

본 발명은 일반적인 에어백 장치의 구성을 가진다. 즉, 사고 발생을 감지하는 감지센서와, 감지센서에 의해 작동기체를 발생시키는 작동가스 발생장치와, 발생된 작동가스를 에어백으로 이송시키는 가스공급관과, 에어백(1)이 접혀져 수납된 수납함(2)을 포함하여 구성된 자동차와 비행기용 에어백 장치에 관한 것이다.The present invention has a configuration of a general airbag apparatus. That is, a sensor for detecting an accident, a working gas generator for generating a working gas by the sensing sensor, a gas supply pipe for transferring the generated working gas to the airbag, and a storage box in which the airbag 1 is folded and received (2). It relates to an airbag device for automobiles and airplanes, including.

본 발명은 상기와 같은 종래의 구성을 공유하고, 이에 본 발명의 특유한 효과를 달성하는 에어백(1)의 구조와, 이의 설치 위치를 특징으로 한다.The present invention is characterized by the structure of the airbag 1 and its installation position which share the conventional configuration as described above, thereby achieving the unique effects of the present invention.

따라서 상기 수납함(2)은 시트(3)의 상부 좌우측에 각각 설치되고; 상기 각각의 에어백(1)은 팽창되었을 때 시트(3)의 등받이에서 일정거리 앞쪽에서 펼쳐져 승객의 상반신의 좌우 절반씩 감쌀 수 있는 공간을 형성시킴;을 특징으로 하는 자동차와 비행기용 상반신 에어백 장치이다.Thus, the holder (2) is respectively installed on the upper left and right sides of the sheet (3); Each of the airbags (1) is inflated in front of the back of the seat (3) when inflated to form a space for wrapping the left and right halves of the upper body of the passenger; .

이와 같은 에어백(1)은 도 1에서와 같이 시트(3)의 상부 양측에 삽입되어 설치되는데, 도 2의 수납함(2)에 졉혀져 수납된다. 물론 시트(3)의 양측에는 에어백(1)이 인출되어 나올 수 있는 틈이 형성되어 있고, 개구된 형태거나 얇은 막으로 막혀져 있는 형태 등 다양할 수 있다.Such an airbag 1 is inserted and installed on both sides of the upper portion of the seat 3 as shown in FIG. 1, and is stowed by the storage box 2 of FIG. 2. Of course, a gap in which the airbag 1 may be drawn out is formed at both sides of the seat 3, and may have various shapes such as an open form or a thin film.

상기의 에어백(1)이 팽창된 상태가 도 3과 내지 도 6에 도시되어 있다. 즉, 시트(3)의 등받이 전방으로 상반신이 위치될 정도의 공간을 두고 시트(3)의 등받이 전방에서 펼쳐지는 구조이다. 따라서 도 6과 같이 시트(3)와 에어백(1)의 사이에 승객의 상반신이 위치된다. 그리고 도 5와 같이 양측 각각의 에어백(1)은 승객의 머리에서부터 가슴까지를 좌우 양분하여 그 각각을 감싸도록 내측에 공간이 형성된 구조이다.The inflated state of the airbag 1 is shown in FIGS. 3 and 6. That is, it is a structure which unfolds in front of the back of the seat | board 3 with the space to which an upper body is located in front of the back of the seat | board 3, and is located. Therefore, the upper body of the passenger is located between the seat 3 and the airbag 1 as shown in FIG. 6. And each airbag 1 on both sides as shown in Figure 5 is a structure formed inside the space to surround each of the left and right by dividing from the head of the passenger to the chest.

사고가 발생하게 하면, 감지센서가 충돌을 인식하고 작동가스 발생장치를 폭발시켜 질소 가스 등의 작동 가스를 발생시켜 에어백(1)을 팽창시킨다. 작동가스는 가스공급관을 통하여 수납함(2)에 접혀져 수납된 에어백(1)으로 송출된다. 작동가스에 의하여 에어백(1)은 도 3의 상태로 팽창하게 된다. 여기서 작동가스 발생장치와 감지센서 및 가스공급관은 도면에 도시되어 있지는 않은데, 이는 에어백 장치의 일반적인 구성 및 작용이므로 생략한 것이다.When an accident occurs, the sensor recognizes the collision and explodes the working gas generator to generate working gas such as nitrogen gas to inflate the airbag 1. The working gas is sent to the airbag 1, which is folded in the holder 2 through the gas supply pipe and accommodated therein. The airbag 1 is inflated in the state of FIG. 3 by the working gas. Here, the operating gas generating device, the sensor and the gas supply pipe are not shown in the drawing, which is omitted since it is a general configuration and operation of the airbag device.

에어백(1)이 팽창하면 수납함(2)의 배출부(4)를 찢거나 확장시키면서 외부로 부풀어 나오게 된다. 여기서 수납함(2)과 배출부(4)의 구조 및 작용 또한 공지의 기술과 같다.When the airbag 1 is inflated, it will bulge outward while tearing or expanding the outlet 4 of the holder 2. Here, the structure and action of the holder 2 and the discharge part 4 are also the same as the known art.

양측의 에어백(1)이 팽창하여 나오게 되면, 승객의 머리와 가슴 등의 상반신을 감싸게 된다. 에어백(1)은 승객 쪽으로 머리와 가슴 등의 상반신을 감쌀 수 있도록 오목한 홈의 형상으로 팽창되고, 마주보는 두 개의 에어백(1)에 의해 형성된 가운데 공간부는 승객의 머리와 가슴 등의 상반신을 완전하게 감쌀 수 있게 된다. 물론 팽창된 에어백(1)과 시트(3)의 등받이 부분과는 승객의 가슴 두께만큼의 공간을 형성하도록 팽창되는 형상을 가진다.When the airbags 1 on both sides are inflated, they wrap around the upper body such as the passenger's head and chest. The airbag 1 is inflated in the shape of a concave groove so as to cover the upper body such as the head and the chest toward the passenger, and the center space formed by the two opposing air bags 1 completely covers the upper body such as the head and the chest of the passenger. I can wrap it. Of course, the inflated airbag 1 and the back portion of the seat 3 have a shape that is inflated to form a space equal to the thickness of the passenger's chest.

따라서 충돌 등의 사고가 발생되면 몸은 안전벨트에 의해 시트(3)에 어느 정 도 고정됨과 동시에, 에어백(1)이 팽창하여 상반신을 감쌈으로써, 차량 내부의 물건이나 유리창 파편 등으로부터 보호함은 물론이고 가슴, 얼굴, 머리 등 치명적인 외상이 우려되는 부분을 보다 효과적으로 보호할 수 있다.Therefore, when an accident such as a collision occurs, the body is fixed to the seat 3 by a seat belt and the air bag 1 is inflated and wrapped around the upper body to protect it from an object inside the vehicle or glass fragments. Of course, you can more effectively protect areas of concern for fatal trauma, such as your chest, face and head.
