본 발명은 도면에 도시된 바와 같이, 차체(10)의 전/후방의 각 모서리의 저부에 장착되어 차체(10)와 노면과의 이격거리를 감지하도록 된 차량고도감지센서(11,12,13,14)와, 상기 차체(10)의 전/후방측 저부에 각각 설치된 에어백유니트(21,22) 및, 상기 차량고도감지센서(11,12,13,14)로부터 감지된 차체(10)와 지면과의 높이차에 따라 에어백유니트(21,22)의 작동을 선택적으로 제어하는 제어유니트(30)로 구성되어져, 차량의 추락사고시 에어백유니트(21,22)의 작동으로 차체(10)가 받게 되는 충격을 일부 흡수하여 탑승자가 받게 되는 충격량을 완화시킬 수 있도록 되어 있다.As shown in the drawing, the vehicle elevation sensor 11, 12, 13 mounted on the bottom of each corner of the front / rear of the vehicle body 10 to detect the separation distance between the vehicle body 10 and the road surface And 14, the airbag units 21 and 22 installed at the front and rear bottoms of the vehicle body 10, and the vehicle body 10 detected by the vehicle altitude detection sensors 11, 12, 13 and 14, respectively. The control unit 30 selectively controls the operation of the airbag units 21 and 22 according to the height difference from the ground, so that the vehicle body 10 may receive the operation of the airbag units 21 and 22 in the event of a vehicle crash. By absorbing some of the shocks, the amount of impact the passengers will receive is alleviated.
여기서, 상기 차량고도감지센서(11,12,13,14)는 예컨대 초음파센서 내지 적외선센서로서, 주행중 차체(10)의 저부에 장착된 차량고도감지센서(11,12,13,14)와 노면과의 사이의 높이차이를 연속적으로 검출할 수 있도록 된 것이다.Here, the vehicle altitude detection sensors 11, 12, 13, and 14 are ultrasonic sensors or infrared sensors, for example, the vehicle altitude detection sensors 11, 12, 13, and 14 mounted on the bottom of the vehicle body 10 while driving. The difference in height between and can be detected continuously.
그리고, 상기 에어백유니트(21,22)는 내부에 접혀진 상태로 수용된 에어백과, 작약과 점화제 및, 가스발생제, 그리고 디퓨저 스크린(이상 도시안됨) 등을 구비한 인플레이터(23,24)를 각각 갖추고 있어, 에어백의 전개시에는 상기 작약에 의해 점화제가 점화되어 가스발생제를 연소시킴에 따라 에어백의 내부로 연소로 발생된 가스가 유입되어 팽창되게 된다.The airbag units 21 and 22 each include an airbag housed in a folded state, and an inflator 23 and 24 including a peony, an ignition agent, a gas generator, and a diffuser screen (not shown). When the airbag is deployed, the gas generated by the combustion flows into the airbag as the ignition agent is ignited and burns the gas generating agent.
또한, 상기 제어유니트(30)는 도 3에 도시된 바와 같이, 차체(10)의 전/후방의 각 모서리의 저부에 장착된 차량고도감지센서(11,12,13,14)로부터 차체(10)와 지면과의 이격거리를 감지받아 이격거리가 기준치이상으로 큰 경우에 상기 인플레이터(23,24)에 작동신호를 입력하도록 된 것으로, 상기 제어유니트(30)는 차량고도감지센서(11,12,13,14)로부터 입력신호를 검출받아 하이레벨과 로우레벨의 출력신호를 선택적으로 발생시키는 비교기(31)와, 상기 에어백유니트(21,22)의 전개를 위한 기준데이터값이 입력된 테이터롬(32) 및, 상기 비교기(31)로부터 입력받은 값을 테이터롬(32)에 입력된 값과 비교하여 차체(10)의 전/후방으로 장착된 에어백유니트(21,22)의 인플레이터(23,24)에 각각 전개신호를 시간적 차이를 두고 선택적으로 인가하는 마이컴(33)으로 구성된다.In addition, the control unit 30 is the vehicle body 10 from the vehicle altitude detection sensor (11, 12, 13, 14) mounted on the bottom of each corner of the front and rear of the vehicle body 10, as shown in FIG. ) And when the separation distance between the ground and the ground is greater than the reference value to input the operation signal to the inflator (23, 24), the control unit 30 is the vehicle altitude detection sensor (11, 12) And a comparator 31 for selectively generating high and low level output signals from input signals 13 and 14, and a data ROM to which reference data values for deployment of the air bag units 21 and 22 are input. And the inflator 23 of the airbag units 21 and 22 mounted to the front and rear of the vehicle body 10 by comparing the value input from the comparator 31 with the value input to the data rod 32. 24 is composed of a microcomputer 33 for selectively applying the development signal to each other with a time difference.
따라서, 차량이 주행중 노면을 이탈하여 노면과 높이차가 있는 지면으로 추락할 경우에는, 먼저 상기 차체(10)의 전/후방측 모서리부위로 각각 장착된 차량고도감지센서(11,12,13,14)가 차체(10)와 노면과의 사이의 높이차를 연속으로 검출하여 제어유니트(30)의 비교기(31)로 입력하게 되고, 이후 상기 마이컴(33)은 비교기(31)로부터 입력받은 현재의 값과 테이터롬(32)에 입력된 기준값 및 현재의 차속을 대비해 차량의 낙하완료시점을 연산하고서 차체(10)의 전/후방에 각각 장착된 에어백유니트(21,22)의 인플레이터(23,24)에 시간차를 두고 전개신호를 보내게 된다.Therefore, when the vehicle leaves the road while driving and falls to the ground having a height difference from the road surface, first, the vehicle altitude detection sensors 11, 12, 13, and 14 mounted to the front and rear corners of the vehicle body 10, respectively. ) Continuously detects the height difference between the vehicle body 10 and the road surface and inputs the same to the comparator 31 of the control unit 30. Then, the microcomputer 33 receives the current input from the comparator 31. Inflators 23 and 24 of the airbag units 21 and 22 mounted on the front and rear of the vehicle body 10, respectively, by calculating the drop completion time of the vehicle in comparison with the reference value and the reference value input to the data ROM 32 and the current vehicle speed. ), The deployment signal is sent with time difference.
이와 같이, 상기 인플레이터(23,24)에 제어유니트(30)로부터의 전개신호가 인가되면, 상기 인플레이터(23,24)내에서 작약과 점화제가 순차적으로 점화되어 가스발생제를 연소시키게 되고, 이 가스발생제의 연소과정에서 발생되는 질소가스가디퓨저 스크린을 거쳐 에어백의 내부로 유입되어 접혀져 내장되어 있던 에어백이 외부로 팽창하면서 전개되게 된다.In this way, when the deployment signal from the control unit 30 is applied to the inflators 23 and 24, the charge and the ignition agent are sequentially ignited in the inflators 23 and 24 to burn the gas generating agent. Nitrogen gas generated during the combustion of the gas generating agent flows into the inside of the airbag through the diffuser screen and is folded and developed while expanding.
이에 따라, 상기 에어백유니트(21,22)내의 에어백이 차체(10)의 하부로 전개되면, 추락하는 차체(10)가 지면과의 충돌을 하게 될 때 받게 되는 충격량이 전개되는 에어백에 의해 일부 흡수될 수 있어 차실내에 탑승한 승객이 받게 되는 충격의 정도는 완화될 수 있어 탑승자의 안전이 도모될 수 있게 된다.Accordingly, when the airbags in the airbag units 21 and 22 are deployed to the lower portion of the vehicle body 10, the impact amount received when the crashed vehicle body 10 collides with the ground is partially absorbed by the airbag that is deployed. Thus, the degree of impact received by passengers in the cabin can be mitigated, thereby enhancing the safety of the occupants.
한편, 본 발명의 실시예에서는 상기 에어백유니트(21,22)가 차체(10)의 전/후방으로 각각 단일개소로 구비된 경우에 한정해서 설명하였으나, 이와 같은 에어백유니트(21,22)는 경우에 따라 다수개소로 구비될 수도 있음은 물론이며, 이때에도 상기 제어유니트(30)는 각각의 에어백유니트(21,22)에 전개신호를 보낼 수 있도록 구성됨은 물론이다.Meanwhile, in the embodiment of the present invention, the air bag units 21 and 22 have been described as being limited to the case where each of the air bag units 21 and 22 is provided at the front and rear of the vehicle body 10, respectively. Of course, it may be provided in a number of places, of course, the control unit 30 is also configured to send a deployment signal to each airbag unit (21, 22) of course.
또한, 상기 차량고도감지센서(11,12,13,14)의 경우도 상기와 마찬가지로 차량에 필요한 부위로 다수개소로 구비될 수 있음은 물론이고, 본 발명에서의 에어백장치는 본 실시예에서와 같이 동일한 작용 및 그에 따른 효과를 발휘할 수 있는 다양한 형태로 변형실시가 가능할 것이다.In addition, the vehicle altitude detection sensor (11, 12, 13, 14) as well as the above may be provided in a number of places necessary for the vehicle, of course, the airbag device in the present invention is Modifications can be made in various forms to achieve the same effect and effects.
이상 설명한 바와 같이 본 발명에 따른 자동차의 에어백장치에 의하면, 자동차가 주행중 추락하는 사고의 발생시 차체의 저부에 장착된 에어백이 전개될 수 있음에 따라, 차체가 지면과의 충돌후 받게 되는 충격량의 정도가 저감될 수 있으므로 탑승자의 안전성을 보다 더 확실하게 보장할 수 있는 효과가 있게 된다.As described above, according to the airbag apparatus of a vehicle according to the present invention, the amount of impact received after the collision with the ground, as the airbag mounted on the bottom of the vehicle can be deployed in the event of an accident that the vehicle falls while driving Since it can be reduced, there is an effect that can more surely ensure the safety of the occupants.
