Description

사이드 에어백{Side air bag}Side air bag}

본 발명은 에어백의 보호영역을 구분하고 상해의 민감도에 따라 내압을 상이하게 전개시켜 승객을 안전하게 보호하는 사이드 에어백에 관한 것이다.The present invention relates to a side airbag that safely protects an occupant by dividing the protection area of the airbag and differently developing internal pressure according to the sensitivity of an injury.

사이드 에어백은 시트의 측면에 장착되는 것으로, 차량에 충돌이 감지되면 시트 측면에서 에어백쿠션이 전개되어 승객의 측면을 보호한다.The side airbag is mounted on the side of the seat, and when a vehicle collision is detected, an airbag cushion is deployed on the side of the seat to protect the passenger's side.

다만, 신차 충돌 안전도테스트가 강화됨에 따라 측면 충돌 평가방법이 달라지고 있고, 이에 강화된 안전도테스트에 대응하기 위해 사이드 에어백의 쿠션형상, 벤트, 격막/가스분배 구조 등이 변경되고 있다.However, as the new car crash safety test is strengthened, the side impact evaluation method is changing, and the cushion shape, vent, diaphragm/gas distribution structure, etc. of the side airbag are being changed to respond to the reinforced safety test.

한편, 기존의 사이드에어백은 내부공간이 상하로 구획됨으로써, 인플레이터에서 제공되는 가스가 상하부 챔버 내에 동시에 분배되면서 승객을 보호하게 된다.Meanwhile, the interior space of the existing side airbag is partitioned vertically, so that gas supplied from the inflator is simultaneously distributed into the upper and lower chambers to protect passengers.

하지만, 상하부 챔버로 구획된 사이드 에어백을 강화된 안전도테스트에 적용시, 가슴 흉부 상해 및 복부 상해 위험이 높은 문제가 있고, 특히 흉부는 상중하부의 변형량이 균일하지 못하여 상해가 특정부위에 집중될 수 있는 문제도 있다.However, when a side airbag divided into upper and lower chambers is applied to an enhanced safety test, there is a problem with a high risk of chest injury and abdominal injury. There is also a problem.

상기의 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.The matters described as the background art above are only for improving understanding of the background of the present invention, and should not be taken as an admission that they correspond to prior art already known to those skilled in the art.

도 1은 본 발명에 따른 사이드 에어백의 측면도이고, 도 2는 본 발명에 따른 사이드 에어백의 배면 형상을 개략적으로 도시한 도면이다.1 is a side view of a side airbag according to the present invention, and FIG. 2 is a view schematically showing the rear shape of the side airbag according to the present invention.

도면을 참조하면, 본 발명은 승객의 골반부분에 대응하는 쿠션(100)의 하부영역에서 전개되는 하부챔버(130); 승객의 복부부분에 대응하는 쿠션(100)의 중간영역에서 하부챔버(130)보다 작은 내압으로 전개되는 중간챔버(120); 및 승객의 흉부부분에 대응하는 쿠션(100)의 상부영역에서 중간챔버(120)보다 작은 내압으로 전개되는 상부챔버(110);를 포함하여 구성이 된다.Referring to the drawings, the present invention includes a lower chamber 130 deployed in a lower region of the cushion 100 corresponding to the pelvis of a passenger; an intermediate chamber 120 deployed with a smaller internal pressure than the lower chamber 130 in the middle region of the cushion 100 corresponding to the passenger's abdomen; and an upper chamber 110 deployed at an internal pressure smaller than that of the intermediate chamber 120 in an upper region of the cushion 100 corresponding to the passenger's chest.

즉, 사이드 에어백의 상하방향 기준으로 승객의 흉부, 복부, 골반에 대응하는 위치에 상부챔버(110), 중간챔버(120), 하부챔버(130)를 각각 구성하고, 각 챔버가 지지하는 신체 부위의 상해 민감도에 따라 각 챔버 내압의 크기가 다르게 전개되도록 구성한다.That is, the upper chamber 110, the middle chamber 120, and the lower chamber 130 are respectively configured at positions corresponding to the chest, abdomen, and pelvis of the passenger in the vertical direction of the side airbag, and the body parts supported by each chamber It is configured so that the magnitude of the pressure in each chamber is developed differently according to the sensitivity of the injury.

구체적으로, 하부챔버(130)는 승객의 골반을 보호하는 챔버로서, 흉부 및 복부보다 둔감하며 3개의 챔버 중 가장 강한 압력으로 전개되는 챔버이다.Specifically, the lower chamber 130 is a chamber that protects the passenger's pelvis, is less sensitive than the chest and abdomen, and is deployed with the strongest pressure among the three chambers.

중간챔버(120)는 승객의 복부를 보호하는 챔버로서, 흉부 대비 상해가 적게 발생하지만 골반보다는 상해에 민감한 부분으로 하부챔버(130)보다 낮은 압력으로 전개된다.The middle chamber 120 is a chamber that protects the passenger's abdomen, and is less prone to injury than the chest, but is more susceptible to injury than the pelvis, and is deployed at a lower pressure than the lower chamber 130.

It becomes a structure through which gas is distributed.

예컨대, 시트백에 고정되는 에어백 후단 내부에 디퓨저(200)가 내장되고, 상기 디퓨저(200) 내부에 인플레이터(300)의 가스가 공급된다.For example, a diffuser 200 is built into the rear end of an airbag fixed to a seatback, and gas from the inflator 300 is supplied to the inside of the diffuser 200 .

그리고, 상기 디퓨저(200)의 상단, 중간, 하단에 상부챔버(110), 중간챔버(120), 하부챔버(130)와 각각 연통되는 상부토출구(210), 중간토출구(220), 하부토출구(230)가 각각 형성됨으로써, 디퓨저(200) 내부의 가스가 상부챔버(110), 중간챔버(120), 하부챔버(130) 내에 분배되어 채워지게 된다.In addition, the upper discharge port 210, the middle discharge port 220, and the lower discharge port ( 230) are formed, respectively, so that the gas inside the diffuser 200 is distributed and filled in the upper chamber 110, the middle chamber 120, and the lower chamber 130.

더불어, 상기 하부토출구(230)의 단면적이 중간토출구(220) 및 상부토출구(210)의 단면적보다 넓게 형성될 수 있다.In addition, the cross-sectional area of the lower discharge port 230 may be formed wider than the cross-sectional areas of the middle discharge port 220 and the upper discharge port 210 .

그리고, 상기 중간토출구(220)의 단면적이 상부토출구(210)의 단면적보다 넓거나 같게 형성될 수 있다.Also, the cross-sectional area of the middle discharge port 220 may be formed to be equal to or larger than the cross-sectional area of the upper discharge port 210 .

즉, 인플레이터(300)의 가스가 디퓨저(200)에 형성된 토출구를 통해 각 챔버에 분배됨으로써, 하부챔버(130)와 연통된 하부토출구(230)의 크기를 나머지 토출구보다 크게 형성하여 하부챔버(130)의 내압을 나머지 챔버 대비 상대적으로 높게 전개시킬 수 있게 된다.That is, as the gas of the inflator 300 is distributed to each chamber through the outlet formed in the diffuser 200, the size of the lower outlet 230 communicating with the lower chamber 130 is made larger than the other outlets so that the lower chamber 130 ) of the internal pressure can be developed relatively higher than the rest of the chamber.

그리고, 승객의 흉부와 복부를 보호하는 상부챔버(110)와 중간챔버(120) 모두 상해 민감도가 높은 보호영역으로서, 상부토출구(210)와 중간토출구(220)의 크기는 동일하게 형성될 수 있지만, 상해 민감도가 상대적으로 더 높은 상부챔버(110)의 내압을 중간챔버(120)보다 낮추도록 상부토출구(210)의 크기를 중간토출구(220)의 크기보다 더 작게 형성할 수도 있다.In addition, both the upper chamber 110 and the middle chamber 120, which protect the chest and abdomen of passengers, are protection areas with high injury sensitivity, and the upper discharge port 210 and the middle discharge port 220 may have the same size, but , The size of the upper discharge port 210 may be smaller than that of the middle discharge port 220 so that the internal pressure of the upper chamber 110, which has a relatively higher injury sensitivity, is lower than that of the middle chamber 120.

더욱이, 본 발명은 상기 하부챔버(130)와 중간챔버(120) 사이와, 중간챔버(120)와 상부챔버(110) 사이가 격막(S)에 의해 구획되고, 상기 격막(S)이 디퓨저(200)의 외면을 덮는 형상으로 재봉되어 각 챔버 간 가스가 직접적으로 연통되지 않도록 구성이 된다.Furthermore, in the present invention, between the lower chamber 130 and the middle chamber 120 and between the middle chamber 120 and the upper chamber 110 are partitioned by a diaphragm (S), and the diaphragm (S) is a diffuser ( 200) is sewn in a shape covering the outer surface, so that the gas between each chamber is not directly communicated.

즉, 하부챔버(130)의 상단과 중간챔버(120) 하단 사이에 격막(S)이 형성되어 재봉되면서 재봉선이 디퓨저(200)의 외면을 감싸는 형상으로 형성되어, 하부챔버(130)와 중간챔버(120) 간 가스가 연통되지 않고, 디퓨저(200)를 통해서만 가스가 연통되는 구조가 된다.That is, while a diaphragm (S) is formed and sewn between the upper end of the lower chamber 130 and the lower end of the middle chamber 120, a seam line is formed in a shape surrounding the outer surface of the diffuser 200, and the lower chamber 130 and the middle chamber The gas is not communicated between (120), and the gas is communicated only through the diffuser (200).

또한, 중간챔버(120)의 상단과 상부챔버(110)의 하단 사이에도 격막(S)이 형성되어 재봉되면서 재봉선이 디퓨저(200)의 외면을 감싸는 형상으로 형성되어, 중간챔버(120)와 상부챔버(110) 간 가스가 연통되지 않고, 디퓨저(200)를 통해서만 가스가 연통되는 구조가 된다.In addition, a diaphragm (S) is formed and sewn between the upper end of the middle chamber 120 and the lower end of the upper chamber 110, and a seam line is formed in a shape surrounding the outer surface of the diffuser 200, so that the middle chamber 120 and the upper Gas is not communicated between the chambers 110, and gas is communicated only through the diffuser 200.

더불어, 상기 인플레이터(300)가 디퓨저(200)의 하부토출구(230)를 향해 분사되도록 구성이 된다.In addition, the inflator 300 is configured to be injected toward the lower discharge port 230 of the diffuser 200.

더 나아가, 상기 인플레이터(300)의 분사구가 디퓨저(200)의 하부토출구(230)에 인접하여 위치하게 된다.Furthermore, the spray hole of the inflator 300 is positioned adjacent to the lower discharge hole 230 of the diffuser 200 .

이에, 인플레이터(300)의 가스가 디퓨저(200)의 하부토출구(230)를 통해 하부챔버(130) 내에 우선 공급됨으로써, 하부챔버(130)의 내압이 나머지 챔버 대비하여 큰 내압으로 전개시킬 수 있게 된다.Accordingly, the gas of the inflator 300 is first supplied into the lower chamber 130 through the lower discharge port 230 of the diffuser 200, so that the internal pressure of the lower chamber 130 can develop to a higher internal pressure than the other chambers. do.

특히, 위와 같은 구조의 챔버 및 디퓨저(200) 구조와, 인플레이터(300)의 배치 형태에 따라 하부챔버(130)가 나머지 챔버 대비 가장 빠르게 전개될 수 있다.In particular, according to the structure of the chamber and diffuser 200 as described above, and the arrangement of the inflator 300, the lower chamber 130 may be deployed most rapidly compared to the other chambers.

구체적으로, 상기 인플레이터(300)의 가스가 하부토출구(230)를 통해 하부챔버(130) 내에 먼저 채워지고; 상기 하부챔버(130) 내의 가스가 디퓨저(200) 내의 중간토출구(220)를 통해 중간챔버(120) 내에 채워지며; 상기 중간챔버(120) 내의 가스가 디퓨저(200) 내의 상부토출구(210)를 통해 상부챔버(110) 내에 채워지게 된다.Specifically, the gas of the inflator 300 is first filled into the lower chamber 130 through the lower discharge port 230; The gas in the lower chamber 130 is filled in the middle chamber 120 through the middle discharge port 220 in the diffuser 200; The gas in the intermediate chamber 120 is filled in the upper chamber 110 through the upper discharge port 210 in the diffuser 200.

따라서, 골반을 보호하는 하부챔버(130)가 우선 전개되고, 복부를 보호하는 중간챔버(120)가 전개된 후, 흉부를 보호하는 상부챔버(110)가 전개됨으로써, 챔버의 내압을 상이하게 전개시킬 수 있게 된다.Therefore, the lower chamber 130 for protecting the pelvis is first deployed, the middle chamber 120 for protecting the abdomen is deployed, and then the upper chamber 110 for protecting the chest is deployed, so that the internal pressure of the chamber is differently developed. be able to do

계속해서, 본 발명은 상기 중간챔버(120)와 상부챔버(110)에 벤트홀이 형성될 수 있다.Subsequently, in the present invention, vent holes may be formed in the middle chamber 120 and the upper chamber 110 .

이에, 상기 벤트홀을 통해 중간챔버(120)보다 상부챔버(110)의 내압을 낮출 수 있게 된다.Accordingly, the internal pressure of the upper chamber 110 can be lowered than that of the intermediate chamber 120 through the vent hole.

일례로, 상기 상부챔버(110)에 형성된 상부벤트홀(112)이 중간챔버(120)에 형성된 중간벤트홀(122)보다 단면적이 넓게 형성될 수 있다.For example, the upper vent hole 112 formed in the upper chamber 110 may have a larger cross-sectional area than the intermediate vent hole 122 formed in the middle chamber 120 .

다른 예시로서, 상기 상부챔버(110)에 형성된 상부벤트홀(112)이 중간챔버(120)에 형성된 중간벤트홀(122)보다 개수가 많이 형성될 수 있다.As another example, the number of upper vent holes 112 formed in the upper chamber 110 may be larger than the number of middle vent holes 122 formed in the middle chamber 120 .

즉, 중간챔버(120)와 상부챔버(110)가 전개되는 과정에서 상부벤트홀(112)을 통해 배출되는 가스유량이 중간벤트홀(122)을 통해 배출되는 가스유량보다 많이 배출됨으로써, 상부챔버(110)의 내압을 중간챔버(120)보다 낮출 수 있게 된다.That is, in the course of the middle chamber 120 and the upper chamber 110 being deployed, the gas flow rate discharged through the upper vent hole 112 is greater than the gas flow rate discharged through the middle vent hole 122, so that the upper chamber The internal pressure of the 110 can be lower than that of the intermediate chamber 120.

즉, 승객의 흉부와 맞닿는 상부챔버(110)의 내측부분에 압력분배구조물(140)이 별도 보강됨으로써, 압력분배구조물(140)에 로딩되는 승객의 하중을 고르게 분배시키게 된다. 따라서, 승객의 흉부에 가해지는 하중을 전체적으로 낮추어 승객을 안전하게 보호하게 된다.That is, the pressure distribution structure 140 is separately reinforced in the inner portion of the upper chamber 110 that comes into contact with the passenger's chest, so that the passenger's load loaded on the pressure distribution structure 140 is evenly distributed. Accordingly, the load applied to the passenger's chest is lowered as a whole to safely protect the passenger.

또한, 승객의 복부와 맞닿는 중간챔버(120)의 내측부분에도 압력분배구조물(140)이 별도 보강될 수 있고, 압력분배구조물(140)에 로딩되는 승객의 하중을 고르게 분배시켜 승객을 보호하게 된다.In addition, the pressure distribution structure 140 can be separately reinforced in the inner part of the intermediate chamber 120 that comes into contact with the passenger's abdomen, and the load of the passengers loaded on the pressure distribution structure 140 is evenly distributed to protect the passengers. .

아울러, 상기 압력분배구조물(140)의 일례로서, 상기 압력분배구조물(140)은 복수의 직물재가 승객로딩면(100a)의 일부를 덮는 형상으로 겹쳐져 재봉될 수 있다.In addition, as an example of the pressure distribution structure 140, the pressure distribution structure 140 may be sewn by overlapping a plurality of fabric materials to cover a portion of the passenger loading surface 100a.

그리고, 상기 압력분배구조물(140)은 상하로 다수 재봉될 수 있다.In addition, the pressure distribution structure 140 may be sewn a plurality of up and down.

또한, 봉제 형태가 상하로 여러번 추가되어 압력을 상하로 더욱 고르게 분배시킬 수 있게 된다.Also, the stitched shape can be added multiple times up and down to more evenly distribute the pressure up and down.

상기 압력분배구조물(140)의 다른 예시로서, 상기 압력분배구조물(140)은 플라스틱재가 사출 성형되어 승객로딩면(100a)의 일부를 덮는 형상으로 접합될 수 있다.As another example of the pressure distribution structure 140, the pressure distribution structure 140 may be bonded to a shape covering a part of the passenger loading surface 100a by injection molding a plastic material.

즉, 압력분배구조물(140)이 별도의 사출물로 성형되어, 상부챔버(110) 또는 중간챔버(120)에 접합될 수 있다.That is, the pressure distribution structure 140 may be molded as a separate injection molding and bonded to the upper chamber 110 or the middle chamber 120 .

한편, 도 7은 본 발명에 따른 중간챔버(120)의 다른 실시예 구조를 도시한 도면이다.On the other hand, Figure 7 is a view showing the structure of another embodiment of the intermediate chamber 120 according to the present invention.

도면을 참조하면, 상기 중간챔버(120)의 좌우 폭방향 너비가 상부챔버(110)의 좌우 폭방향 너비보다 길게 형성될 수 있다.Referring to the drawings, the width of the middle chamber 120 in the left and right width directions may be longer than the width of the upper chamber 110 in the left and right width directions.

즉, 도어트림에 위치한 암레스트의 돌출된 부분과 복부 사이에 대응되는 중간챔버(120)의 크기를 상부챔버(110) 또는 하부챔버(130) 대비하여 좌우 폭을 크게 형성함으로써, 측면 충돌시 복부의 충격 흡수구간을 크게 만들어 승객의 복부 상해를 보호하게 된다.That is, the size of the middle chamber 120 corresponding between the protruding part of the armrest located on the door trim and the abdomen is formed to have a larger left and right width compared to the upper chamber 110 or the lower chamber 130, so that the abdomen in case of a side collision By making the shock absorption section large, it protects passengers from abdominal injuries.

이 경우, 상기 중간챔버(120)에 형성된 중간벤트홀(122)은 차실 내부의 트림과 맞닿는 차체로딩면(100b)을 벗어나는 위치에 형성될 수 있다.In this case, the intermediate vent hole 122 formed in the intermediate chamber 120 may be formed at a position outside the vehicle body loading surface 100b in contact with the trim inside the vehicle compartment.

즉, 압력조절을 위해 형성된 중간벤트홀(122)이 암레스트에 의해 막히지 않도록 중간벤트홀(122)이 암레스트와 마주하는 위치에서 벗어나도록 형성할 수 있다.That is, the middle vent hole 122 may be formed to deviate from a position facing the armrest so that the middle vent hole 122 formed for pressure control is not blocked by the armrest.

이하에서, 본 발명에 따른 사이드 에어백의 전개 작동에 대해 설명하면, 차량의 충돌신호가 입력되는 경우, 인플레이터(300)가 폭발하여 디퓨저(200) 내에 가스가 공급된다.Hereinafter, the deployment operation of the side airbag according to the present invention will be described. When a vehicle collision signal is input, the inflator 300 explodes and gas is supplied into the diffuser 200.

이때에, 인플레이터(300)의 분사구가 하부토출구(230)와 인접한 위치에서 하부토출구(230)를 향하도록 구비됨으로써, 인플레이터(300)의 가스가 하부토출구(230)를 통해 하부챔버(130) 내에 우선하여 채워지게 되고, 이에 하부챔버(130)가 강한 내압으로 우선 전개된다.At this time, the injection hole of the inflator 300 is provided to face the lower discharge port 230 from a position adjacent to the lower discharge port 230, so that the gas of the inflator 300 enters the lower chamber 130 through the lower discharge port 230. It is filled first, and thus the lower chamber 130 is first deployed with a strong internal pressure.

이어서, 하부챔버(130)에 채워지는 가스와 함께 디퓨저(200) 내부의 가스가 디퓨저(200)의 중간토출구(220)를 통해 중간챔버(120) 내에 채워지게 됨으로써, 중간챔버(120)가 전개된다.Subsequently, the gas inside the diffuser 200 together with the gas filled in the lower chamber 130 is filled in the intermediate chamber 120 through the intermediate discharge port 220 of the diffuser 200, so that the intermediate chamber 120 is deployed. do.

이 후, 중간챔버(120)에 채워지는 가스와 함께 디퓨저(200) 내부의 가스가 디퓨저(200)의 상부토출구(210)를 통해 상부챔저 내에 채워지게 됨으로써, 상부챔버(110)가 전개된다.Thereafter, the gas inside the diffuser 200 together with the gas filled in the intermediate chamber 120 is filled in the upper chamber through the upper discharge port 210 of the diffuser 200, so that the upper chamber 110 is deployed.

이와 같이, 본 발명은 골반을 보호하는 하부챔버(130)가 우선 전개되고, 복부를 보호하는 중간챔버(120)가 전개된 후, 흉부를 보호하는 상부챔버(110)가 전개된다.As such, in the present invention, the lower chamber 130 for protecting the pelvis is first deployed, the middle chamber 120 for protecting the abdomen is deployed, and then the upper chamber 110 for protecting the chest is deployed.

즉, 승객의 흉부, 복부, 골반에 대응하여 에어백의 보호영역을 3개의 챔버로 구분하고, 상해의 민감도가 큰 챔버 영역일수록 내압을 작게 전개함으로써, 상해 민감도가 높은 신체 부위에 대한 부상 위험을 방지하여 승객을 안전하게 보호하게 된다.In other words, the protection area of the airbag is divided into three chambers corresponding to the chest, abdomen, and pelvis of the passenger, and the internal pressure is developed smaller in the chamber area with greater injury sensitivity, thereby preventing the risk of injury to body parts with higher injury sensitivity. This will keep passengers safe.
