Description

자동차의 에어백 시스템Car airbag system

본 고안은 자동차의 에어백 시스템에 관한 것으로, 좀더 상세하게는 하나의 메인에어백에 복수의 인플레이터에서 발생한 가스에 의해서 각각 팽창되는 복수의 에어백을 내장시켜 작동시간의 단축으로 신뢰도를 높이며 소용량의 인플레이터를 적용할 수 있도록 하는 자동차의 에어백 시스템에 관한 것이다.The present invention relates to an airbag system of an automobile, and more particularly, a plurality of airbags that are inflated by gas generated from a plurality of inflators are embedded in one main airbag, thereby increasing reliability by shortening operation time and applying a small capacity inflator. It relates to a car airbag system that allows.

도 1 에 도시된 바와같이, 종래의 에어백 시스템은 차체에 설치되는 다수의 가속도센서(SR)의 검출신호를 인가받는 에어백제어모듈(ACM)이 차량의 충돌상태를 감지하여 점화전류를 운전석 및 조수석 에어백의 임플레이터(11)로 인가함으로써 상기 임플레이터(11)가 가스발생제를 연소시킴에 따라 운전석 및 조수석의 에어백(12)이 팽창되도록 구성된다.As shown in FIG. 1, in the conventional airbag system, an airbag control module (ACM) that receives detection signals of a plurality of acceleration sensors (SR) installed in a vehicle body detects a collision state of a vehicle and supplies an ignition current to a driver's seat and a passenger seat. The airbag 12 of the driver's seat and the passenger seat is inflated as the impeller 11 burns the gas generating agent by applying the airbag to the platen 11 of the airbag.

그러나, 종래에는 상기 에어백(12)의 부피가 안전규격을 만족하는 일정부피로 되어야 하는데, 상기 에어백(12)이 단일구조로 이루어지기 때문에 부피가 큰 상기 에어백(12)에 일정시간 내에 가스를 주입하기가 어려워 급속히 가스를 확산시킬 수 있는 인플레이터(11)를 제작하여야 하므로 전체적인 에어백 시스템의 코스트를 상승시키게 되는 문제점이 있었다.However, in the related art, the volume of the airbag 12 should be a constant volume that satisfies safety standards. Since the airbag 12 has a single structure, gas is injected into the bulky airbag 12 within a predetermined time. Since it is difficult to manufacture the inflator 11 capable of rapidly diffusing gas, there is a problem in that the cost of the overall airbag system is increased.

또한, 기존의 에어백 시스템의 신뢰성은 뛰어나지만, 혹시나 발생할 지 모르는 작동불량시에는 탑승자의 안전을 전혀 보장할 수 없게 된다는 문제점이 있었다.In addition, although the reliability of the existing airbag system is excellent, there is a problem in that it can not guarantee the safety of the occupants at all in case of a malfunction that may occur.

전술한 문제점을 해결하기 위해 안출된 본 고안은 하나의 메인에어백 내에 복수의 에어백을 구비시키고 상기 복수의 에어백을 복수의 인플레이터에서 발생한 가스에 의해서 각각 팽창시키도록 함으로써, 인플레이터에 소용량의 것을 적용할 수 있고 에어백의 팽창시간을 단축할 수 있도록 하려는 목적이 있다.The present invention devised to solve the above problems is to provide a plurality of airbags in one main airbag and to inflate the plurality of airbags by gas generated from a plurality of inflators, respectively, so that a small amount can be applied to the inflator. And to shorten the inflation time of the airbag.

전술한 목적을 달성하기 위한 본 고안에 따르면, 차체에 설치되어 차량충돌시의 충격력을 검출하는 다수의 가속도센서와, 상기 다수의 가속도센서의 신호로 차량충돌을 감지하여 점화전류를 출력하는 에어백제어모듈과, 상기 에어백제어모듈의 출력에 따라 팽창가스를 발생하는 복수의 인플레이터와, 상기 각각의 인플레이터에서 발생한 가스에 의해 각각 팽창되며 메인에어백 내에 구비되는 복수의 에어백으로 구성되는 것을 특징으로 하는 자동차의 에어백 시스템이 제공된다.According to the present invention for achieving the above object, a plurality of acceleration sensors installed on the vehicle body for detecting the impact force when the vehicle crash, and airbag control for detecting the vehicle collision with the signals of the plurality of acceleration sensors to output the ignition current A module, a plurality of inflators for generating an inflation gas according to the output of the airbag control module, and a plurality of airbags respectively inflated by the gas generated in the respective inflators and provided in the main airbag. An airbag system is provided.

이하, 도면을 참조하여 본 고안의 바람직한 실시예를 더욱 상세히 설명하며 종래와 동일한 부분에 대해서는 동일한 도면부호를 부여하기로 한다.Hereinafter, with reference to the drawings will be described a preferred embodiment of the present invention in more detail and will be given the same reference numerals for the same parts as in the prior art.

도 2 는 본 고안에 의한 에어백 시스템의 구성도이고, 도 3 은 본 고안에 의한 에어백의 작동상태도로서, 차체에 설치되어 차량충돌시의 충격력을 검출하는 다수의 가속도센서(SR)와, 상기 다수의 가속도센서(SR)의 신호로 차량충돌을 감지하여 점화전류를 출력하는 에어백제어모듈(ACM)이 구비되는 것은 종래의 에어백 시스템과 동일하다.2 is a configuration diagram of the airbag system according to the present invention, Figure 3 is an operating state diagram of the airbag according to the present invention, a plurality of acceleration sensors (SR) installed on the vehicle body for detecting the impact force when the vehicle crash, The airbag control module (ACM) for detecting a vehicle collision with the signal of the acceleration sensor SR and outputting the ignition current is provided as in the conventional airbag system.

그러나, 본 고안은 상기 에어백제어모듈(ACM)의 출력된 점화전류로 가스발생제를 연소시켜 팽창가스를 발생하는 복수의 인플레이터(21,22)가 구비되고, 상기 각각의 인플레이터(21,22)에서 발생한 가스가 주입되어 각각 팽창되는 복수개의 에어백(31,32)이 구비되고, 상기 두 에어백(31,32)이 메인에어백(30)에 내장되어 구성되는 특징이 있다.However, the present invention is provided with a plurality of inflators (21, 22) for generating an expansion gas by burning a gas generator with the output ignition current of the airbag control module (ACM), each of the inflators (21, 22) A plurality of airbags 31 and 32 are provided which are inflated by injecting the gas generated in the air, and the two airbags 31 and 32 are built in the main air bag 30.

상기 메인에어백(30)의 부피를 종래의 에어백(12)의 부피와 동일하게 한다면 상기 메인에어백(30)에 내장된 두 에어백(31,32)은 상기 종래의 에어백(12)에 비해 반 정도의 부피로 구성함으로도, 종래의 에어백(12)과 동일한 충격흡수 효과를 기대할 수 있음은 당연하다. 또, 상기 두 에어백(31,32)의 부피가 종래의 에어백(12)의 부피보다 절반임에 따라 상기 본 고안의 임플레이터(21,22)의 가스가 주입되는 시간도 절반으로 단축되므로, 상기 두 에어백(31,32)의 팽창에 따른 메인에어백(30)의 팽창시간은 종래의 에어백(12)이 팽창되던 시간보다 절반으로 단축할 수 있게 된다.If the volume of the main air bag 30 is equal to the volume of the conventional air bag 12, the two air bags 31 and 32 embedded in the main air bag 30 are about half of the size of the conventional air bag 12. Even if the volume is configured, it is natural that the same shock absorbing effect as the conventional airbag 12 can be expected. In addition, since the volume of the two airbags 31 and 32 is half the volume of the conventional airbag 12, the time for injecting the gas of the inflator 21 and 22 of the present invention is also shortened by half. The inflation time of the main airbag 30 according to the inflation of the two airbags 31 and 32 can be shortened by half than the time when the conventional airbag 12 is inflated.

또한, 상기 두 에어백(31,32)에 각각 주입되는 가스량도 종래의 에어백(12)에 비해서 절반정도이면 되므로, 상기 본 고안의 두 인플레이터(21,22)에 종래의 인플레이터(11)에 비해 절반정도의 소용량의 것을 적용할 수 있게 된다.In addition, since the amount of gas injected into each of the two airbags 31 and 32 may be about half of that of the conventional airbag 12, the two inflators 21 and 22 of the present invention are half of those of the conventional inflator 11. It is possible to apply a small amount of precision.

또, 본 고안은 차량충돌사고시, 상기 두 에어백(31,32) 중의 하나가 인플레이터의 작동불량 등에 의해 팽창되지 않더라도 다른 하나의 에어백이 팽창하여 승객을 보호하게 된다.In addition, the present invention is to protect the passenger by inflating the other airbag even if one of the two airbags (31,32) is not inflated due to malfunction of the inflator or the like during a vehicle crash accident.

이상에서 설명한 바와같이 본 고안은 하나의 메인에어백 내에 복수의 인플레이터에서 발생한 가스에 의해서 각각 팽창되는 복수의 에어백을 구비시킴으로써 에어백의 팽창시간을 단축시켜 승객을 보호하는 신뢰도를 높이게 됨은 물론이고 인플레이터에 소용량의 것을 적용할 수 있게 되어 전체적인 에어백 시스템의 코스트를 낮춰 실용화시킬 수 있게 되는 효과가 있는 것이다.As described above, the present invention includes a plurality of airbags that are each inflated by gases generated by a plurality of inflators in one main airbag, thereby shortening the inflation time of the airbag to increase the reliability of protecting passengers, as well as a small capacity in the inflator. 'S can be applied to reduce the cost of the overall airbag system has the effect that can be put to practical use.
