차량의 동승석 에어백장치{PASSENGER AIRBAG APPARATUS IN VEHICLE}Passenger seat airbag device in vehicle {PASSENGER AIRBAG APPARATUS IN VEHICLE}

본 발명은 차량의 동승석 에어백장치에 관한 것으로서, 더 상세하게는 차량 충돌 사고 발생시 동승석 탑승자의 목상해를 최소화한 차량의 동승석 에어백장치에 관한 것이다.The present invention relates to a passenger airbag apparatus of a vehicle, and more particularly, to a passenger airbag apparatus of a vehicle which minimizes the injury to the occupant of a passenger in the event of a vehicle crash.

일반적으로 차량용 에어백 시스템은 충돌 사고 발생시 에어백쿠션을 전개시켜 충격을 완화하고, 승객이 차체 밖으로 튕겨 나가는 것을 방지하는 안전장치이다. 차량용 에어백 시스템은 정면 충돌시 앞좌석 승객을 보호하는 운전석 에어백(Driver Air-Bag, DAB)과 동승석 에어백(Passenger Air-Bag, PAB), 측면 충돌시 승객의 옆을 보호하는 사이드 에어백(Side Air-Bag, SAB) 및 커튼 에어백(Curtain Air-Bag, CAB) 등으로 구분된다.In general, an airbag system for a vehicle is a safety device that mitigates shock by deploying an airbag cushion in the event of a collision and prevents a passenger from being thrown out of the vehicle body. In-vehicle airbag systems include Driver Air-Bag (DAB) and Passenger Air-Bag (PAB) to protect front passengers in frontal collisions, and Side Airbags to protect passengers' sideways in side collisions. -Bag, SAB) and curtain air bag (Curtain Air-Bag, CAB) and the like.

도 1 및 도 2에 도시된 바와 같이, 동승석 에어백은 탑승자의 머리 및 상체의 에어백쿠션 접촉 부위에 따라 목상해 크기의 변동이 심하다는 특성을 갖는다. 목상해치를 최소화함과 동시에, 안정성을 최대화하기 위해서는 탑승자의 머리 및 상체가 이상적으로 거동하여야 하는데, 이러한 거동을 구현하는 것은 쉽지 않은 일이다. 즉, 차량의 충돌 사고 발생시 탑승자의 목이 에어백쿠션에 의해 과도하게 전방(도 2참조) 또는 후방(도 1참조)으로 회전하는 것을 방지하는 것이 상술한 탑승자의 이상적 거동 여부를 결정짓은 가장 중요한 요소인 것이다.As shown in Figure 1 and 2, the passenger seat airbag has a characteristic that the size of the neck injury is severe depending on the airbag cushion contact portion of the occupant's head and upper body. In order to minimize wooden hatches and maximize stability, the head and upper body of the occupant should ideally behave, which is not easy to implement. In other words, preventing the occupant's neck from rotating excessively forward (see Fig. 2) or backward (see Fig. 1) by the airbag cushion during the collision of the vehicle is the most important factor in determining the ideal behavior of the above-mentioned passenger. will be.

차량의 북미 수출을 위해서는 NCAP(북미 충돌 안전도 평가) 테스트를 통과하여야 한다. 이러한 동승석 NCAP 상품성 평가에서 가장 가중치가 높은 요소가 목상해 테스트인 바, 목상해 저감 기술은 필수적으로 개선이 필요한 기술 분야이다.The vehicle must pass the North American Collision Safety Assessment (NCAP) test to export to North America. As the most weighted factor in the evaluation of Dong-Seok NCAP's marketability is the visual inspection, the visual reduction technique is an essential technical field that needs improvement.

차량의 충돌 사고 발생시, 탑승자의 목상해치와 관련된 Y축 방향의 모멘트(MY)이다. 이러한 MY 때문에 탑승자의 전,후방 목꺽임 현상이 발생되는 바, 이러한 MY 형성에 기여하는 힘이 FX(차량의 전후 방향 힘) 및 FZ(차량의 상하 방향 힘)이다. 즉, 차량의 전후 또는 상하 방향에서 전달되는 힘에 의해서 탑승자의 목은 Y축(차량의 측면 방향 축)을 중심으로 과도하게 회전하게 되고, 이로 인하여 탑승자의 목상해치는 증가하는 문제점이 발생되는 것이다. The moment in the Y-axis relative to the occupant's neck hatch (M Y ) in the event of a vehicle crash. Because of this M Y , the front and rear crutches of the occupant are generated. The forces contributing to the formation of the M Y are F X (forward and backward force of the vehicle) and F Z (up and down force of the vehicle). That is, the neck of the occupant is excessively rotated about the Y-axis (lateral axis of the vehicle) by the force transmitted in the front and rear or up and down direction of the vehicle, thereby causing a problem of increasing the neck injury of the occupant.

상기한 배경기술로서 설명된 사항들은 본 발명의 배경에 대한 이해 증진을 위한 것일 뿐, 이 기술분야에서 통상의 지식을 가진 자에게 이미 알려진 종래기술에 해당함을 인정하는 것으로 받아들여져서는 안 될 것이다.It should be understood that the foregoing description of the background art is merely for the purpose of promoting an understanding of the background of the present invention and is not to be construed as adhering to the prior art already known to those skilled in the art.

본 발명은 이러한 종래의 문제점을 해결하기 위해 차량의 전후 또는 상하 방향에서 전달되는 힘에 의해서 탑승자의 목이 차량의 측면 방향 축을 중심으로 과도하게 회전되는 것을 방지한 차량의 동승석 에어백장치를 제공하는데 그 목적이 있다.The present invention provides a passenger seat airbag device for preventing the passenger's neck from being excessively rotated about the lateral axis of the vehicle by the force transmitted in the front and rear or up and down direction of the vehicle to solve the conventional problems. There is a purpose.

이러한 목적을 달성하기 위한 본 발명에 따른 차량의 동승석 에어백장치는 인플레이터; 차량의 전후 방향 힘(FX)과 차량의 상하 방향 힘(FZ)에 의해 발생되는 모멘트(MY)를 차량의 측면 방향 힘(FY)에 의한 모멘트(MZ)로 전환시킬 수 있도록 전개되는 에어백쿠션을 포함한다.A passenger seat airbag device for a vehicle according to the present invention for achieving the above object is an inflator; The moment M Y generated by the front and rear force F X of the vehicle and the vertical force F Z of the vehicle can be converted into the moment M Z by the lateral force F Y of the vehicle. Airbag cushions that are deployed.

상기 에어백쿠션은 좌측챔버와, 우측챔버와, 상기 좌측챔버 및 우측챔버를 분할하는 내부격막을 포함하고, 상기 좌측챔버와 우측챔버의 내부 압력이 다르게 형성될 수 있도록 상기 좌측챔버 및 우측챔버에 상기 인플레이터에서 발생된 가스를 분배하여 공급하는 디퓨저를 더 포함하는 것을 특징으로 한다.The airbag cushion includes a left chamber, a right chamber, and an inner diaphragm dividing the left chamber and the right chamber, and the left and right chambers may have different internal pressures. It further comprises a diffuser for distributing and supplying the gas generated in the inflator.

상기 디퓨저는 상기 내부격막을 관통하여 상기 좌측챔버 및 우측챔버와 연결되며, 상기 좌측챔버 및 우측챔버로 각각 연결되는 상기 디퓨저의 좌측유출구와 우측유출구의 크기는 서로 다른 것을 특징으로 한다.The diffuser penetrates through the inner diaphragm and is connected to the left and right chambers, and the sizes of the left and right outlets of the diffuser connected to the left and right chambers are different from each other.

본 발명은 상기한 기술적 구성으로 인해 차량의 충돌 사고 발생시 차량의 동승석 탑승자의 목상해치가 감소된다.According to the present invention, the neck hatch of the passenger occupant of the vehicle is reduced when the collision of the vehicle occurs.

이하에서는 첨부된 도면을 참조하여 본 발명의 바람직한 실시 예에 따른 차량의 동승석 에어백장치에 대하여 설명한다.Hereinafter, with reference to the accompanying drawings will be described with respect to the passenger seat airbag apparatus of a vehicle according to an embodiment of the present invention.

본 발명에서 언급되는 X방향 축은 차량의 전후 방향 축, Y방향 축은 차량의 좌우 방향 축, Z방향 축은 차량의 상하 방향 축을 의미한다.In the present invention, the X-direction axis refers to the front and rear direction axis of the vehicle, the Y-direction axis refers to the horizontal axis of the vehicle, and the Z-direction axis refers to the vertical axis of the vehicle.

NCAP의 동승석 상품성 평가에 있어서, 목상해 성능과 관련된 힘은 차량의 전후 방향 힘(FX)과 차량의 상하 방향 힘(FZ) 및 이로부터 발생되는 모멘트(MY)이다. 즉, MY는 동승석 탑승자 목을 차량의 전,후 방향으로 꺽이게 하는 모멘트인데, 이러한 모멘트 생성에 영향을 미치는 인자가 바로, FX 및 FZ인 것이다.In the evaluation of the passenger seat marketability of the NCAP, the forces associated with the neck injury performance are the front and rear force F X of the vehicle and the vertical force F Z of the vehicle, and the moment M Y generated therefrom. That is, M Y is a moment that causes the passenger's neck to be bent in the forward and backward directions of the vehicle. The factors influencing the moment generation are F X and Is F Z.

이러한 MY를 감소시키기 위해서는 FX 와 FZ를 감소시켜야 하는데, 실질적으로 목상해치 계산에 있어서, 고려되지 않는 요소가 FY인 바, 상대적으로 이를 증가시킴으로써 FX 와 FZ를 감소시키는 것이 본 발명의 중요한 개념이라 할 수 있다. FY의 증가는 MZ의 증가를 의미한다. 결국, FY 및 MZ를 증가시킴으로써, 차량의 충돌 사고 발생시 MY의 크기를 감소시킬 수 있는 바, 차량의 동승석 탑승자의 목상해를 최소화할 수 있다.Such M Y To reduce F X and To be reduced to F Z, according to a substantially poles hatch calculated, it does not take into account factors F Y the bars, to increase this relative by F and X Reducing F Z is an important concept of the present invention. The increase in F Y Means an increase in M Z. In the end, F Y and By increasing M Z , it is possible to reduce the size of M Y in the event of a crash of the vehicle, thereby minimizing the visual injury of the occupant of the vehicle.

도 3은 상술한 개념을 구현하기 위한 본 발명의 차량의 동승석 에어백장치를 나타낸 도면이다.3 is a view showing a passenger seat airbag device of the vehicle of the present invention for implementing the above-described concept.

도 3에 도시된 바와 같이, 본 발명은 인플레이터(10), 에어백쿠션(20) 및 디퓨저(30)를 포함한다. 차량의 충돌 사고 발생시 인플레이터(10)에서 발생된 가스가 에어백쿠션(20)에 공급됨으로써, 차량의 동승석 탑승자(P)를 보호한다.As shown in FIG. 3, the present invention includes an inflator 10, an airbag cushion 20, and a diffuser 30. The gas generated in the inflator 10 is supplied to the airbag cushion 20 when the collision of the vehicle occurs, thereby protecting the passenger occupant P of the vehicle.

에어백쿠션(20)은 좌측챔버(22), 우측챔버(24) 및 내부격막(26)을 포함한다. 내부격막(26)은 에어백쿠션(20)의 공간을 좌측챔버(22)와 우측챔버(24)로 구분한다. 또한, 디퓨저(30)는 인플레이터(10)로부터 공급되는 가스를 좌측챔버(22) 및 우측챔버(24)로 공급하는 바, 좌측챔버(22)와 우측챔버(24)의 내부 압력은 서로 달리 형성된다.The airbag cushion 20 includes a left chamber 22, a right chamber 24, and an inner diaphragm 26. The inner diaphragm 26 divides the space of the airbag cushion 20 into the left chamber 22 and the right chamber 24. In addition, the diffuser 30 supplies the gas supplied from the inflator 10 to the left chamber 22 and the right chamber 24, and internal pressures of the left chamber 22 and the right chamber 24 are different from each other. do.

즉, 좌측챔버(22)와 우측챔버(24)의 내부 압력이 서로 다르기 때문에, 차량의 충돌 사고가 발생한 경우, 동승석 탑승자(P)의 머리는 내부압력이 높은 측의 챔버로부터 내부압력이 낮은 측의 챔버 방향으로 회전하게 된다. 이러한 방향으로의 회전은 목상해치 계산에 있어서 고려되지 않는 방향의 회전인 바, 차량의 동승석 탑승자(P)의 목상해치는 최소화될 수 있고, NCAP 동승석 상품성 평가에서 좋은 결과를 얻을 수 있다.That is, since the internal pressures of the left chamber 22 and the right chamber 24 are different from each other, in the event of a collision of the vehicle, the head of the passenger occupant P has a low internal pressure from the chamber of the high internal pressure side. It rotates in the chamber direction of the side. The rotation in this direction is a rotation in a direction that is not considered in the calculation of the wooden hatch, so that the wooden hatch of the passenger occupant P of the vehicle can be minimized and a good result can be obtained in the NCAP passenger marketability evaluation.

디퓨저(30)는 좌측챔버(22)와 우측챔버(24) 내부 압력이 서로 다르게 형성될 수 있도록 좌,우측챔버(22,24)에 서로 다른 양의 가스를 공급한다.The diffuser 30 supplies different amounts of gas to the left and right chambers 22 and 24 so that the pressure inside the left chamber 22 and the right chamber 24 may be different from each other.

이를 위하여, 디퓨저(30)는 내부격막(26)을 관통하여 좌측챔버(22) 및 우측챔버(24)를 연결시키되, 좌측챔버측과 우측챔버측으로 형성된 좌측유출구(32)와 우측유출구(34)는 서로 다른 크기로 형성된다. 즉, 좌측유출구(32)와 우측유출구(34)의 크기를 달리하여, 인플레이터(10)에서 각각 좌측챔버(22) 및 우측챔버(24)로 공급되는 가스양을 조절함으로써, 좌,우측챔버(22,24)의 내부 압력을 달리 형성하는 것이다.To this end, the diffuser 30 penetrates the inner diaphragm 26 to connect the left chamber 22 and the right chamber 24, and the left outlet 32 and the right outlet 34 formed on the left chamber side and the right chamber side, respectively. Are formed in different sizes. That is, by varying the size of the left outlet 32 and the right outlet 34, by adjusting the amount of gas supplied from the inflator 10 to the left chamber 22 and the right chamber 24, the left and right chamber 22 The internal pressure of (24) is differently formed.

도 4 내지 도 6을 참조로 본 발명의 차량의 동승석 에어백장치의 작동 메커니즘을 설명한다.An operation mechanism of the passenger airbag device of the vehicle of the present invention will be described with reference to FIGS. 4 to 6.

도 4에 도시된 바와 같이, 차량의 충돌 사고가 발생되면, 에어백쿠션(20)의 좌측챔버(22)와 우측챔버(24)의 내부 압력을 서로 달리 형성된다. 차량의 동승석 탑승자(P)의 머리가 에어백쿠션(20)에 접촉하기 이전이므로, FY 및 MZ에 의한 충격은 거의 없다.As shown in FIG. 4, when a collision accident of the vehicle occurs, internal pressures of the left chamber 22 and the right chamber 24 of the airbag cushion 20 are different from each other. Since the head of the passenger occupant P of the vehicle is before contacting the airbag cushion 20, there is little impact by F Y and M Z.

도 5에 도시된 바와 같이, 좌측챔버(22)보다 우측챔버(24) 내부 압력이 더 고압인 경우, 차량의 동승석 탑승자(P)의 머리는 에어백쿠션(20)에 접촉하면서 좌측으로 회전하게 된다. 즉, Z축 방향을 중심으로 반시계 방향으로 회전하는 바, FY 및 MZ는 증가하고, FX 및 MY는 감소한다.(FZ는 차량의 상하 방향으로 전달되는 힘인데, 실질적으로 이는 미미하다.)As shown in FIG. 5, when the pressure inside the right chamber 24 is higher than that of the left chamber 22, the head of the passenger occupant P of the vehicle rotates to the left while contacting the airbag cushion 20. do. That is, as it rotates counterclockwise around the Z axis direction, F Y and M Z increase and F X and M Y decrease (F Z is a force transmitted in the up and down direction of the vehicle. This is minor.)

도 6에 도시된 바와 같이, 차량의 동승석 탑승자(P)의 머리가 Z축 방향을 중심으로 반시계 방향으로 더 회전하면, FY 및 MZ는 더 증가하고, 상대적으로 FX 및 MY는 더 감소하는 바, 목표로 하는 감소된 목상해치를 얻을 수 있다.As shown in FIG. 6, when the head of the passenger occupant P of the vehicle is further rotated counterclockwise around the Z axis direction, F Y and M Z are further increased, and relatively F X and M Y Is further reduced, so that the targeted reduced wooden hatch can be obtained.

본 발명은 특정한 실시예에 관련하여 도시하고 설명하였지만, 이하의 실용신안등록청구범위에 의해 제공되는 본 발명의 기술적 사상을 벗어나지 않는 한도 내에서, 본 발명이 다양하게 개량 및 변화될 수 있다는 것은 당 업계에서 통상의 지식을 가진 자에게 있어서 자명할 것이다.While the invention has been shown and described with respect to specific embodiments, it will be appreciated that the invention can be variously modified and modified without departing from the spirit thereof provided by the following utility model registration claims.
