Description

자동차의 파 사이드 에어백 장치far side airbag device in car
본 발명은 자동차의 파 사이드 에어백 장치에 관한 것으로, 더욱 상세하게는 자동차의 측면 충돌시 탑승자 간의 충돌을 방지해서 탑승자를 보호하는 자동차의 파 사이드 에어백 장치에 관한 것이다. The present invention relates to a far side airbag device for a vehicle, and more particularly, to a far side airbag device for a vehicle that protects an occupant by preventing a collision between occupants during a side collision of the vehicle.
일반적으로, 자동차 에어백 장치는 자동차 충돌 시 충격 감지 센서의 신호에 따라 에어백에 가스를 주입하여 급속히 에어백을 팽창시킴으로써 탑승자를 보호하는 안전장치이다. In general, an automobile airbag device is a safety device that protects occupants by rapidly inflating the airbag by injecting gas into the airbag according to a signal from an impact sensor when a vehicle crashes.
이러한 에어백 장치는 자동차에 마련되는 스티어링 휠이나 데쉬보드, 시트, 측벽 등에 설치되고, 자동차의 충돌시 탑승자의 전면이나 측면을 향해 팽창되어 탑승자를 보호한다. Such an airbag device is installed in a steering wheel, dashboard, seat, sidewall, etc. provided in a vehicle, and inflates toward the front or side of the occupant when the vehicle collides to protect the occupant.
즉, 자동차에는 운전석 및 동승석 전방에서 전개되는 정면 에어백, 측면 충돌이 발생한 방향(이하 '충돌측'이라 함)에서 전개되어 승객을 보호하는 커튼 에어백 및 사이드 에어백, 승객의 무릎을 보호하기 위한 무릎에어백 등이 마련될 수 있다.That is, in automobiles, front airbags deployed in front of the driver's seat and passenger's seat, curtain airbags and side airbags deployed in the direction in which a side collision occurred (hereinafter referred to as 'impact side') to protect passengers, and knee airbags to protect passengers' knees An airbag or the like may be provided.
사이드 에어백에는 승객과 도어 등의 차체 구성 부재 사이에 팽창 전개하고, 측면 충돌의 충격으로 내측으로 돌출되는 차체의 구성 부재로부터 탑승자를 보호하는 이른바 니어 사이드 에어백(near side airbag)과, 측면 충돌의 반동으로 차량의 내측으로 이동하는 탑승자의 이동을 제한하는 파 사이드 에어백(far side airbag) 또는 센터 사이드 에어백(center side airbag)이 있다.Side airbags include a so-called near side airbag that inflates and deploys between a passenger and a vehicle body component such as a door and protects an occupant from a vehicle body component that protrudes inward due to the impact of a side collision, There is a far side airbag or a center side airbag that restricts the movement of passengers moving inside the vehicle.
상기 파 사이드 에어백은 자동차의 충돌 사고 발생시, 탑승자와 그 옆에 착석한 탑승자 사이에서 전개되어 탑승자의 상호 충돌을 방지하고, 탑승자에게 가해지는 충격을 감소시키며, 탑승자가 충격에 의해 자동차 외부로 튕겨져 나가는 것을 방지하는 기능을 한다. The far side airbag is deployed between an occupant and a occupant seated next to the occupant in the event of a car crash, preventing mutual collision between the occupants, reducing the impact applied to the occupant, and the occupant being thrown out of the car by the impact function to prevent
예를 들어, 본 출원인은 하기의 특허문헌 1 및 특허문헌 2에 파 사이드 에어백 장치 구성을 개시하여 특허 출원한 바 있다. For example, the present applicant has applied for a patent by disclosing the configuration of a far side airbag device in Patent Document 1 and Patent Document 2 below.
상기한 바와 같은 기능을 수행하기 위해, 파 사이드 에어백은 탑승자와 부딪힐 때 안정적으로 탑승자를 지지하며 그 충격을 흡수할 수 있어야 한다. In order to perform the above functions, the far side airbag should be able to stably support the occupant and absorb the impact when colliding with the occupant.
그러나 종래기술에 따른 파 사이드 에어백은 설치되는 위치의 특성상 에어백이 회전되거나 이동되지 않도록 하는 그 어떠한 구조물에 의해 지지되지 못하기 때문에, 탑승자가 충돌되는 경우 충돌되는 탑승자를 충분히 지지하기 어려운 문제점이 있었다. However, since the far side airbag according to the prior art cannot be supported by any structure that prevents the airbag from rotating or moving due to the nature of the installed position, it is difficult to sufficiently support the occupant who is collided when the occupant collides.
또한, 탑승자는 자동차의 측면 충돌 발생시, 자동차의 측면 방향을 따라 이동하면서 전개된 파 사이드 에어백에서 빠져나가는 슬립이 발생하는 문제점이 있었다. In addition, there is a problem in that the occupant slips out of the deployed far side airbag while moving along the side of the vehicle when a side collision of the vehicle occurs.
이로 인해, 종래기술에 따른 파 사이드 에어백은 다른 탑승자와 충돌을 방지해서 탑승자를 안전하게 보호하는데 한계가 있었다. For this reason, the far side airbag according to the prior art has limitations in safely protecting the occupants by preventing collisions with other occupants.

특히, 에어백 쿠션(20)의 상부와 하부는 각각 중앙부를 중심으로 탑승자의 머리 부위와, 복부 또는 골반 부위를 향해 접어질 수 있다. In particular, the upper and lower portions of the airbag cushion 20 may be folded toward the occupant's head and abdomen or pelvis, respectively, centering on the central portion.
이를 위해, 에어백 쿠션(20)은 복수의 챔버로 구획되고, 대략 중앙부를 중심으로 서로 접어질 수 있다. To this end, the airbag cushion 20 is partitioned into a plurality of chambers, and can be folded to each other about a central portion.
예를 들어, 에어백 쿠션(20)은 탑승자의 가슴 부위를 중심으로 탑승자의 가슴 상부와 목 및 머리 부위에 대응되는 상부 챔버(21)와, 탑승자의 가슴 하부와 복부 부위에 대응되는 하부 챔버(22)를 포함할 수 있다. For example, the airbag cushion 20 includes an upper chamber 21 corresponding to the upper chest, neck and head of the occupant centered on the occupant's chest, and a lower chamber 22 corresponding to the lower chest and abdominal area of the occupant. ) may be included.
하부 챔버(22)는 탑승자의 상체 전체와 함께 골반 부위까지 보호할 수 있도록 하방으로 연장될 수도 있다. The lower chamber 22 may extend downward to protect the entire upper body of the occupant and up to the pelvis.
상부 챔버(21)와 하부 챔버(22)는 팽창하지 않는 비팽창 영역을 형성하는 챔버월(23)에 의해 단면이 대략 '<' 형상으로 접어질 수 있다.The upper chamber 21 and the lower chamber 22 may be folded into a substantially '<' shape in cross section by the chamber wall 23 forming a non-expandable region that does not expand.
챔버월(23)은 도 2에 도시된 바와 같이, 측면에서 보았을 때 대략 '┘' 형상을 이루도록 에어백 쿠션(20)의 전단에서 후측을 향해 수평하게 배치되는 수평부(24)와, 수평부(24)의 후단에서 상방을 향해 수직하게 배치되는 수직부(25)를 포함할 수 있다. 수평부(24)와 수직부(25)는 각각 직선이나 곡선 형상, 원 형상이나 타원 형상, 다각 형상 등 다양한 형상으로 형성될 수 있다. As shown in FIG. 2, the chamber wall 23 includes a horizontal portion 24 horizontally disposed from the front end of the airbag cushion 20 toward the rear to form an approximate '┘' shape when viewed from the side, and a horizontal portion ( 24) may include a vertical portion 25 vertically disposed upward toward the rear end. The horizontal portion 24 and the vertical portion 25 may be formed in various shapes, such as a straight or curved shape, a circular or elliptical shape, or a polygonal shape, respectively.
따라서 에어백 쿠션(20)의 상부 챔버(21)와 하부 챔버(22)는 챔버월(23)의 수평부(24)를 중심으로 서로 겹쳐지도록 접어질 수 있다.Accordingly, the upper chamber 21 and the lower chamber 22 of the airbag cushion 20 may be folded to overlap each other around the horizontal portion 24 of the chamber wall 23 .
예를 들어, 상부 챔버(21)와 하부 챔버(22)는 대략 60° 내지 120°의 각도를 이루면서 접어질 수 있다. For example, the upper chamber 21 and the lower chamber 22 may be folded while forming an angle of approximately 60° to 120°.
그리고 에어백 쿠션(20)의 상부 챔버(21)는 챔버월(23)의 수직부(25)에 의해 팽창되지 않고 오목하게 팽창 전개될 수 있다. 여기서, 수직부(25)는 탑승자의 팔과 어깨 부위에 대응되는 위치에 배치될 수 있다. In addition, the upper chamber 21 of the airbag cushion 20 is not inflated by the vertical portion 25 of the chamber wall 23 and can be expanded and deployed concavely.
