본 발명은 자동차의 안전에 중요한 역할을 하는 에어백의 갑작스런 폭발 팽창시에 밀폐된 차량내부에 급상승하는 압력을 저하시켜 이로인해 발생하는 안전사고의 위험성을 방지되게한 에어백 팽창시의 내부압력 감소장치에 관한 것이다.The present invention is directed to a device for reducing the internal pressure during inflation of an airbag that reduces the sudden pressure rising inside the sealed vehicle during sudden explosion inflation of an airbag that plays an important role in the safety of a vehicle. It is about.
에어백이 장치된 자동차의 경우 갑작스런 충격등에 의하여 에어백이 폭발하여 급팽창할시에 밀폐된 차량 내부공간에서 핸들등중에 내장되어 있던 에어백이 큰 부피로 급팽창하면서 그 부피만큼 차량내부의 압력이 급상승하여 이로 인해 탑승객에게 중요한 상해를 입히게 되는 문제점이 있었다.In the case of a vehicle equipped with an airbag, when the airbag explodes due to a sudden impact, the airbag built in the steering wheel expands to a large volume in a sealed interior space, and the pressure inside the vehicle rapidly increases by that volume. This caused a serious injury to the passengers.
본 발명은 에어백의 급팽창시에 전기한 바와 같은 문제점을 제거코저 자동차 리어시트 후방에 장착된 트레이판을 회동되게 축설하여 이를 압력감소기에 의해 지지되게 하여 충격감지센서가 충격을 감지하여 그 신호를 에어백에 보낼시에 압력감소기에도 동시에 보내게 하여 그 자체의 하중 및 스프링의 탄발력으로 그 롯드를 하강시켜 트레이판을 다운시켜 자동차 실내공간을 트렁크 공간과 관통시켜 그만큼 실내공간을 넓히게 하여 그만큼 압력을 감소시키므로서 에어백의 급팽창에도 실내공간의 압력에 큰 변화를 주지 않게한 에어백 팽창시의 내부압력 감소 장치를 발명한 것이다.The present invention eliminates the problems as described above during the inflation of the airbag by rotating the tray plate mounted on the rear seat of the car to be rotated to be supported by a pressure reducer so that the shock sensor detects the shock to detect the signal When sending it to the airbag, it is sent to the pressure reducer at the same time, and the load is lowered by its own load and the spring force. The present invention has been invented to reduce the internal pressure during airbag inflation, thereby reducing the pressure of the indoor space even when the airbag is inflated.
이하, 본 발명의 실시예를 첨부도면의 의하여 상세히 설명한다.Hereinafter, embodiments of the present invention will be described in detail by the accompanying drawings.
리어시트(1) 후방에 장착되는 트레이판(2)의 일측부를 힌지(3)에 의해 축설되게 하고, 그 타측부는 압력감소기(4)에 의해 지지축설되게 하되, 압력감소기(4)는 실린더(5) 내부공간에 롯드(6)를 스프링(7)으로 탄설하여 그 선단을 전기한 트레이판(2)에 축설되게 하고, 하방에는 개폐밸브(8)를 설치하여 통상의 충격감지센서(9)과 연결하여 그 전기적 신호에 의해 작동되게 한 것이다.One side of the tray plate 2 mounted behind the rear seat 1 is built up by the hinge 3, and the other side thereof is supported by the pressure reducer 4, and the pressure reducer 4 The rod 6 is installed in the inner space of the cylinder 5 with a spring 7 so that the tip thereof is built up on the tray plate 2, and an opening / closing valve 8 is installed below the ordinary shock sensor. In connection with (9), it is operated by the electric signal.
도면중 미설명 부호 10은 에어백, 11 은 공기재 공급용 에어펌프이다.In the figure, reference numeral 10 denotes an air bag, and 11 denotes an air pump for supplying air.
이와같은 본 발명의 작용효과를 상세히 설명하면 다음과 같다.Referring to the effect of the present invention in detail as follows.
본 발명의 내부압력 감소장치를 장착한 자동차는 평상시에는 그 트레이판(2)이 일측이 힌지(3)에 의해 축설된채 타측은 공기압력에 의해 롯드(6)가 전진되어 있는 압력감소기(4)의 선단에 축설지지되어 있으므로 통상의 자동차와 마찬가지로 트레이판(2)이 리어시트(1)의 후방에서 평형을 유지한채 물건등을 올려 놓은 트레이판(2)으로서의 역할을 하는 것이다.A vehicle equipped with the internal pressure reducing device of the present invention is a pressure reducer in which the rod 6 is advanced by air pressure while the tray plate 2 is normally built up by the hinge 3 on one side thereof. Since it is erected and supported at the tip of 4), the tray plate 2 serves as the tray plate 2 on which objects and the like have been placed on the rear of the rear seat 1 in the same manner as in a normal car.
이와같은 자동차가 갑자기 타물체와의 충돌로 충격을 받을시에는 충격감지센서(9)가 이를 감지하여 그 전기적 신호를 에어백(10)과 마그네틱 개폐밸브(8)에 동시에 보내게 되므로 에어백(10)이 폭발팽창되는 순간에 압력감소기(4)의 개폐밸브(8)가 오픈되어 그 내부의 공기가 배출되면서 그 트레이판(2)의 자체 무게 및 스프링(7)의 탄발력으로 압력감소기(4)의 롯드(6)가 후진하여 그 선단에 축설되어 있는 트레이판(2)을 다운(Down)시켜 자동차의 실내공간을 트렁크의 내부공간과 관통시켜 자동차의 실내공간을 그만큼 일시적으로 넓히게 되는 효과를 갖는 것이다.When such a vehicle is suddenly impacted by a collision with another object, the shock sensor 9 detects this and sends an electrical signal to the airbag 10 and the magnetic on / off valve 8 at the same time. At the moment when the explosion expands, the on / off valve 8 of the pressure reducer 4 is opened and the air therein is discharged, thereby reducing the pressure reducer by the self-weight of the tray plate 2 and the elasticity of the spring 7. The rod 6 of 4) moves backwards and downs the tray plate 2 arranged on the tip of the rod 6 to penetrate the interior space of the car with the interior space of the trunk, thereby temporarily widening the interior space of the car. To have.
그러므로, 에어백(10)이 폭발하여 급팽창하더라도 에어백에 의해 급상승하는 압력을 흡수하여 결과적으로 에어백이 팽창하기전의 공기압력과 동일한 공기압력을 유지할 수 있는 것이다.Therefore, even if the airbag 10 explodes and expands, it can absorb the pressure rising by the airbag and consequently maintain the same air pressure as the air pressure before the airbag expands.
그러므로 갑작스런 압력의 증가로 발생되는 승객의 상해를 방지할 수 있는 것이며, 이의 재 설치시에는 공기 재공급용 에어펌프(11)등에 의해 공기를 실린더(5)내에 재충진하게 되면 다시 롯드(6)가 전진하여 트레이판(2)을 상승시켜 원래의 구성으로 복원되는 것이다.Therefore, it is possible to prevent injuries of passengers caused by sudden increase in pressure, and when it is re-installed, if air is refilled into the cylinder 5 by an air pump 11 for resupply of air, the rod 6 again. Is advanced to raise the tray plate 2 to be restored to its original configuration.
이상과 같은 본 발명은 자동차의 충돌시에 안전을 보장하는 에어백의 기능을 유지하면서도 에어백의 폭발 팽창시에도 그 압력변화로 인한 사고 위험성까지 없앤 매우 효과적인 고안이라 하겠다.The present invention as described above will be a very effective devise to maintain the function of the airbag to ensure safety in the event of a crash of the vehicle, even when the explosion of the airbag, even the risk of accidents due to the pressure change.
