Description
본 발명은 차량용 다단팽창 에어백에 관한 것으로, 보다 상세하게는 양 측면을 먼저 팽창시킨 후 중앙부분을 팽창시킬 수 있도록 된 차량용 다단팽창 에어백에 관한 것이다.The present invention relates to a multistage inflated airbag for a vehicle, and more particularly, to a multistage inflated airbag for a vehicle that is capable of inflating both sides and then inflating a central portion.
일반적으로 고속으로 주행하는 차량의 경우 탑승객의 안전을 위한 여러 장치들이 장착되는바, 이러한 장치들 중 에어백은 차량의 충돌 시 충돌에 의한 충격력을 감지하여 가스를 고속으로 분사하면서 소정 크기로 쿠션을 부풀려서 관성에 의해 이동되는 탑승객의 가슴 위쪽 부위의 충격을 흡수하도록 된 것으로 이와 같이, 탑승객의 충격을 흡수하여 부상을 방지하는 에어백은 도 1에 도시된 바와 같이 가스의 폭발을 통해 부풀려지면서 소정크기로 빠르게 팽창하여 충격을 완화·흡수하여 부상을 방지하게 되어 있다.In general, a vehicle driving at high speed is equipped with a number of devices for the safety of the passenger. Among these devices, the airbag inflates the cushion to a predetermined size while injecting gas at a high speed by detecting the impact force caused by the collision during the collision of the vehicle. In this way, the airbag that absorbs the impact of the upper part of the passenger's chest moved by inertia, and thus absorbs the passenger's shock and prevents an injury, is inflated through a gas explosion as shown in FIG. It is inflated to alleviate and absorb shocks to prevent injury.
즉, 상기 에어백은 차량의 전방부위에 구비된 충격감지센서의 신호를 전달받아 설정된 로직에 따라 판단하는 제어기(도시되어 있지 않음)로부터 신호를 받아 빠르게 폭발하여 가스를 분출하도록 차량의 소정부위에 고정플레이트(10)를 매개로 장착되는 인플레이터(20)와, 이 인플레이터(20)에 형성된 다수의 배출구(21)를 통해 분사되는 가스에 의해 빠르게 부풀려지면서 팽창하는 쿠션으로 이루어지되, 이 쿠션은 상기 인플레이터(20)에 고정되어 팽창되는 로워쿠션(30)과, 이 로워쿠션(30)에 바느질로 결합되어 팽창되는 어퍼쿠션(40)으로 이루어진다.That is, the airbag is fixed to a predetermined part of the vehicle to explode quickly by receiving a signal from a controller (not shown) that receives the signal of the shock sensor provided in the front part of the vehicle and judges it according to a set logic. An inflator 20 mounted through a plate 10 and a cushion that expands rapidly while being inflated by a gas injected through a plurality of outlets 21 formed in the inflator 20 are expanded. It is composed of a lower cushion 30 is fixed and inflated to 20, and the upper cushion 40 is expanded by stitching coupled to the lower cushion 30.
그러나, 이와 같은 에어백의 쿠션은 인플레이터(20)의 작동 시 전방위로 형성된 인플레이터(20)의 배출구(21)를 통해 가스가 분사 즉, 도 1에 도시된 바와 같이 되는 모든 방향으로 고압의 가스가 급격하게 분사되면서 순식간에 상·하·좌·우방향으로 균등하게 팽창됨에 따라 근접위치의 승객이나 신체가 작은 여성 탑승객의 경우 고압·고속분출가스에 의한 상해를 유발하는 문제가 있게 된다.However, the cushion of the airbag such that the gas is injected through the outlet 21 of the inflator 20 formed in all directions during the operation of the inflator 20, that is, the high-pressure gas suddenly in all directions as shown in FIG. As it is rapidly sprayed in the up, down, left, and right directions, it is rapidly inflated, so that a passenger or a small female passenger in a close position may cause injury due to high pressure and high velocity jet gas.
이에 본 발명은 상기와 같은 점을 감안하여 발명된 것으로, 인플레이터에서분출되는 가스를 쿠션의 양 측면으로 보내 1차적으로 양 측면부를 팽창시킨 후 중앙부위를 팽창시켜 고압가스의 고속분사에 의한 근접 탑승객의 신체부상을 방지함에 그 목적이 있다.Accordingly, the present invention has been invented in view of the above-mentioned point, and the gas ejected from the inflator is sent to both sides of the cushion to inflate both side portions first, and then to expand the central portion so that the close passengers by the high-speed injection of high pressure gas. The purpose is to prevent body injury.
상기와 같은 목적을 달성하기 위한 본 발명은, 에어백이 차량에 가해지는 충격을 감지·판단하는 제어기로부터 신호를 받아 고압·고속가스를 분출하는 인플레이터와, 이 인플레이터의 측면을 따라 형성된 다수의 배출구를 통해 분사되는 가스에 의해 팽창하는 쿠션으로 이루어지되, 이 쿠션은 상기 인플레이터에 고정되면서 양 측면으로 팽창되는 로워쿠션과, 이 로워쿠션에 바느질로 결합되면서 로워쿠션이 충진된 후 가스가 유입되도록 상기 인플레이터의 상부에 고정된 분리수단을 매개로 분리된 어퍼쿠션으로 이루어진 것을 특징으로 한다.The present invention for achieving the above object is an inflator for ejecting high-pressure, high-speed gas in response to a signal from the controller for detecting and determining the impact applied to the vehicle, and a plurality of outlets formed along the side of the inflator Consists of a cushion that is expanded by the gas injected through, the cushion is fixed to the inflator and the lower cushion is expanded to both sides, the lower cushion is coupled to the lower cushion by sewing the lower cushion is filled so that the gas flows in Characterized in that the upper cushion separated by a separation means fixed to the upper portion of the.

이하 본 발명의 실시예를 첨부된 예시도면을 참조로 상세히 설명한다.Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.
도 2는 본 발명에 따른 차량용 다단팽창 에어백의 구성도를 도시한 것인바, 본 발명의 에어백은 차량에 가해지는 충격을 감지·판단하는 제어기로부터 신호를 받아 고압·고속가스를 분출하는 인플레이터(20)와, 이 인플레이터(20)의 측면을 따라 형성된 다수의 배출구(21)를 통해 분사되는 가스에 의해 팽창하는 쿠션으로 이루어지되, 이 쿠션은 상기 인플레이터(20)에 고정되면서 양 측면으로 팽창되는 로워쿠션(30)과, 이 로워쿠션(30)에 바느질로 결합되면서 로워쿠션(30)이 충진된 후 가스가 유입되도록 상기 인플레이터(20)의 상부에 고정된 분리수단(50)을 매개로 분리된 어퍼쿠션(40)으로 이루어진다.Figure 2 shows a block diagram of a multi-stage inflating airbag for a vehicle according to the present invention, the airbag of the present invention receives a signal from the controller for detecting and determining the impact applied to the vehicle inflator 20 for ejecting high-pressure, high-speed gas ) And a cushion that expands by a gas injected through a plurality of outlets 21 formed along the side of the inflator 20, the cushion being fixed to the inflator 20 and expanding to both sides. The cushion 30 and the lower cushion 30 are separated by means of a separating means 50 fixed to the upper portion of the inflator 20 so that the gas is introduced after the lower cushion 30 is filled. It consists of an upper cushion 40.
여기서, 상기 로워쿠션(30)에는 어퍼쿠션(40)에 대해 상대적으로 튀어올라 팽창되어 양 측면에서 승객의 얼굴을 감싸도록 서브쿠션(30')이 형성되어진다.Here, the lower cushion 30 is formed with a sub-cushion 30 'so as to spring up and expand relative to the upper cushion 40 to cover the passenger's face on both sides.
또한, 상기 분리수단(50)은 인플레이터(20)의 상부에 고정부재(51)를 매개로 일 단이 고정되어 상기 로워쿠션(30)과 어퍼쿠션(40)의 공간을 분리하면서 격막(52)이 구비되되, 이 격막(52)에는 상기 로워쿠션(30)으로 유입된 가스가 어퍼쿠션(40)으로 유입되는 흐름통로인 벤트홀(52')이 형성되어진다.In addition, the separating means 50 is one end is fixed to the upper portion of the inflator 20 via the fixing member 51 to separate the space between the lower cushion 30 and the upper cushion 40, the diaphragm 52 Is provided, the diaphragm 52 is formed with a vent hole (52 ') which is a flow path for the gas introduced into the lower cushion (30) flows into the upper cushion (40).
이에 따라, 차량의 충돌에 의해 인플레이터(20)가 폭발하여 고압·고속의 가스를 인플레이터(20)의 측면으로 형성된 배출구(21)를 통해 배출하게 되면, 상기 인플레이터(20)의 상부부위에 고정된 분리수단(50)의 격막(52)에 의해 어퍼쿠션(40)으로의 유입이 차단되면서 로워쿠션(30)과 이에 일체로 형성된 서브쿠션(30')을 팽창시키게 된다.Accordingly, when the inflator 20 is exploded due to the collision of the vehicle and the high pressure and high speed gas is discharged through the outlet 21 formed at the side of the inflator 20, the inflator 20 is fixed to the upper part of the inflator 20. The inflow into the upper cushion 40 is blocked by the diaphragm 52 of the separating means 50, thereby expanding the lower cushion 30 and the sub cushion 30 ′ integrally formed therewith.
이어, 상기 로워쿠션(30)과 서브쿠션(30')을 팽창시킨 고압·고속의 가스는 분리수단(50)의 격막(52)에 형성된 벤트홀(52')을 통해 상기 로워쿠션(30)의 중앙부위에 형성된 어퍼쿠션(40)에 유입되어 팽창시키게 된다.Subsequently, the high-pressure and high-speed gas in which the lower cushion 30 and the sub cushion 30 'are inflated is passed through the lower hole 30 through a vent hole 52' formed in the diaphragm 52 of the separating means 50. It is introduced into the upper cushion 40 formed in the central portion of the inflated.
즉, 본 발명의 에어백은 쿠션의 양측을 먼저 팬창시킨 후 그 중앙 부위를 팽창시키게 되므로 전술한 종래의 경우와 같이 빠르게 팽창되는 중앙부위의 쿠션에 의한 신체부상이 방지되어 진다.That is, since the airbag of the present invention first expands both sides of the cushion and then expands the central portion thereof, body injuries caused by the cushion of the central portion that are rapidly inflated as in the conventional case described above are prevented.
이상 설명한 바와 같이 본 발명에 의하면, 에어백의 쿠션이 순식간에 상·하·좌·우방향으로 균등하게 팽창되지 않고 양 측면부위가 1차적으로 팽창된 후 그중앙부위를 2차적으로 팽창되므로 근접위치의 승객이나 신체가 작은 여성 탑승객의 경우에도 고압·고속분출가스에 의한 상해를 유발하지 않는 효과가 있게 된다.As described above, according to the present invention, the airbag cushion is not inflated in the up, down, left, and right directions in an instant, and both side portions are inflated first, and then the central portion thereof is inflated secondly so that the cushion is in close proximity. In the case of passengers or small female passengers, there is an effect that does not cause injury by high-pressure and high-speed jet gas.
또한, 본 발명은 어퍼쿠션을 로워쿠션이 감싸 상대적으로 돌출 높이를 낮추는 서브쿠션을 형성하므로 상기 어퍼쿠션부위로 충돌하는 신체부위를 측면에서 감쌀 수 있으므로 충격의 흡수·분산을 더욱 효과적으로 하게 됨은 물론이다.In addition, since the lower cushion wraps the upper cushion to form a sub-cushion that relatively lowers the height of the protrusion, the present invention can wrap the body part colliding with the upper cushion part from the side, thereby more effectively absorbing and dispersing the impact. .
