Description

차량용 사이드 에어백 시스템 {SIDE AIR BAG SYSTEM FOR VEHICLE}Side air bag system for vehicle {SIDE AIR BAG SYSTEM FOR VEHICLE}

본 발명은 차량용 사이드 에어백 시스템에 관한 것이며, 상세하게는 사이드 에어백 시스템의 에어백 쿠션의 전개 구조에 관한 것이다.The present invention relates to a vehicle side airbag system, and more particularly, to a deployment structure of an airbag cushion of a side airbag system.

주지하는 바와 같이 차량은 시트 백의 사이드 볼스터에 사이드 에어백 모듈을 내장하여 측면 충돌시에 탑승객의 옆구리 측으로 팽창 전개시킴으로써 안전성을 증대하고 있다.As is well known, the vehicle increases safety by incorporating a side airbag module in the side bolster of the seat back and expanding and expanding it to the side of the passenger at the time of side collision.

종래의 사이드 에어백 시스템은 도 1에서 참조되고 도 4 및 도 5에 도시한 바와 같이, 시트백(10)의 사이드 볼스터(11)를 볼스터 표피재(12)와 측면 표피재(13)를 측면 전방에서 봉제부(14)로 연결하여 형성 함과 아울러 상기 볼스터 표피재(12) 및 측면 표피재(13)의 내면에 내피재(15a)(15b)를 적층하고, 상기 사이드 볼스터(11)의 내부에는 패드(16)를 설치한 것이다.The conventional side airbag system is referred to in FIG. 1 and as shown in FIGS. 4 and 5, the side bolster 11 of the seatback 10 with the bolster skin 12 and the side skin 13 at the side front. It is formed by connecting to the sewing portion 14, and the inner skin material (15a) 15b laminated on the inner surface of the bolster skin material 12 and the side skin material 13, the inside of the side bolster 11 The pad 16 is installed.

한편 상기 패드(16)에는 수납부(19)를 형성함과 아울러 상기 수납부(19)에 봉제부(14) 방향으로 삼각형의 전개 유도홈(20)을 형성하여서, 상기 수납부(19)에 에어백 쿠션(22´)을 접어넣은 에어백 모듈(22)을 프레임(17)에 고정하여 내장한 것이다. On the other hand, the pad 16 is provided with an accommodating portion 19, and in the accommodating portion 19 to form a triangular development guide groove 20 in the direction of the sewing portion 14, to the accommodating portion 19 The airbag module 22 having the airbag cushion 22 'folded therein is fixed to the frame 17 and built therein.

그리고 상기 에어백 모듈(22)은 비닐 또는 부직포 등으로 된 모듈 커버(23)에 넣음과 아울러 상기 모듈 커버(23)의 에어백 전개 유도홈(20) 측에는 슬릿(미도시)을 형성하고, 또한 상기 측면 표피재(13)의 내면에 적층하는 내피재(15b)는 상기 측면 표피재(13)의 물성치(강성, 신율, 마찰력 등)와 동등 이상의 물성치를 가지도록 하여서 측면 충돌시 에어백 쿠션(22´)이 팽창 전개될 때 모듈 커버(23)의 슬릿이 파손되면서 전개 유도홈(20)으로 유도 전개되면서 봉제부(14)를 파손시키고 사이드 볼스터(11)의 전방으로 팽창 전개되도록 한 것이다. The airbag module 22 is placed in a module cover 23 made of vinyl or nonwoven fabric, and a slit (not shown) is formed on the airbag deployment guide groove 20 side of the module cover 23. The inner skin material 15b laminated on the inner surface of the skin material 13 has a property value equal to or higher than that of the side skin material 13 (stiffness, elongation, friction force, etc.) so that the airbag cushion 22 'at the time of side impact. When the expansion and expansion of the module cover 23, the slit is broken while being guided to the deployment guide groove 20 to damage the sewing portion 14 and to expand and deploy in front of the side bolster (11).

그러나 상기한 차량용 사이드 에어백은 측면 표피재(13)의 내면에 내피재(15b)를 적층하고 에어백 모듈(22)은 모듈 커버(23)에 넣은 것임으로 구조가 복잡하여 원가가 상승하고, 그리고 에어백 모듈(22)을 넣는 모듈 커버(23)는 연질이고 강성이 취약한 비닐 또는 부직포 등이며, 또한 상기 모듈 커버(23)는 에어백 모듈(23) 만을 감싸는 형상임으로 수납부(19)와 전개 유도홈(20) 사이는 공간부가 형성됨으로 에어백 쿠션(22´)이 팽창 전개될 때 방향 유도가 양호하지 못하고, 부풀음의 제한 기능이 없음으로 에어백 쿠션(22´)이 정확한 위치로 전개되지 못하는 문제점이 있게 되는 것이다.However, the vehicle side airbag is laminated with the inner skin material 15b on the inner surface of the side skin material 13 and the airbag module 22 is placed in the module cover 23, which is complicated in structure and the cost increases. The module cover 23 into which the module 22 is placed is made of soft and weak rigid vinyl or nonwoven fabric, and the module cover 23 surrounds only the airbag module 23 so that the housing 19 and the deployment guide groove ( 20) there is a problem that the induction of the direction is not good when the airbag cushion 22 'is inflated and deployed because the space portion is formed, and the airbag cushion 22' is not deployed to the correct position because there is no limit function of inflation. will be.

본 발명은 상기한 문제점을 시정하여, 구조를 단순화하고, 에어백 쿠션의 전개 방향 유도를 양호하게 한 차량용 사이드 에어백 시스템을 제공하는 것을 목적으로 한다. SUMMARY OF THE INVENTION An object of the present invention is to provide a vehicle side airbag system in which the above-mentioned problems are corrected, to simplify the structure, and to improve the induction direction of the airbag cushion.

한편 상기 패드(16)에는 수납부(19)를 형성함과 아울러 상기 수납부(19)에 봉제부(14) 방향으로 삼각형의 전개 유도홈(20)을 형성하여서, 상기 수납부(19)에 에어백 쿠션(22´)을 접어넣은 에어백 모듈(22)을 프레임(17)에 고정하여 내장한 것이다. On the other hand, the pad 16 is provided with an accommodating portion 19, and in the accommodating portion 19 to form a triangular development guide groove 20 in the direction of the sewing portion 14, to the accommodating portion 19 The airbag module 22 having the airbag cushion 22 'folded therein is fixed to the frame 17 and built therein.

그리고 상기 에어백 모듈(22)을 상기 측면 표피재(13)와 강성, 신율, 마찰력 등의 물성치가 동등하거나 동등 이상의 물성치를 가진 모듈 커버(자루)(30)에 넣음 과 아울러 상기 모듈 커버(30)의 출구에 상기 전개 유도홈(20)에 위치되는 전개 유도편(31a)(31b)을 일체로 형성하여서 된 것이며, 상기 모듈 커버(30)는 강성은 양호하고, 신율 및 마찰력은 적은 재질의 것으로 선정하는 것이다.In addition, the airbag module 22 is placed in a module cover (bag) 30 having the same physical properties as the side skin material 13 and the physical properties such as rigidity, elongation, friction, and the like, and the module cover 30. The induction guide pieces 31a and 31b positioned in the deployment guide groove 20 are integrally formed at the exit of the module guide, and the module cover 30 is made of a material having good rigidity and low elongation and frictional force. Is to select.

상기 전개 유도편(31a)(31b)은 상기 전개 유도홈(20)과 동일한 단면 형상인 삼각형으로 형성하여 전개 유도홈(20)의 벽에 지지함으로써 에어백 쿠션(22´)의 전개 유도를 더욱더 양호하게 한 것이다.The deployment guide pieces 31a and 31b are formed in a triangle having the same cross-sectional shape as the deployment guide groove 20 to support the wall of the deployment guide groove 20 to further guide deployment of the airbag cushion 22 '. It is made.

그리고 상기 전개 유도편(30a)(31b)에는 전개성능 조절 수단(32)을 설치함으로써 전개 성능을 양호하게 조절할 수 있으며, 상기 전개 성능 조절 수단(32)은 훅(똑딱이 단추) 벨크로, 지퍼락 등으로 형성할 수 있다.And by deploying the deployment performance adjusting means 32 to the deployment guide piece (30a) (31b) it is possible to satisfactorily adjust the development performance, the development performance adjustment means 32 is hook (tick button) Velcro, zipper lock, etc. Can be formed.

이상과 같은 본 발명은 측면 충돌시 에어백 쿠션(22´)이 팽창될 때 에어백 모듈(22)을 넣은 측면 표피재(13)와 그 물성치가 동등하거나 동등 이상의 물성치를 가진 모듈 커버(30)에 의하여 에어백 쿠션(22´)의 부풀음이 방지되고, 또한 에어백 쿠션(22´)이 전개 유도홈(20) 측으로 전개될 때 모듈 커버(30)의 출구에 일체로 형성한 전개 유도편(31a)(31b)에 의하여 봉제부(14) 방향으로 정확하게 유도됨으로 에어백 쿠션(22´)이 사이드 볼스터(11)의 측면 전방으로 양호하게 전개되는 것이다.As described above, according to the present invention, when the airbag cushion 22 'is inflated during side impact, the side cover material 13 having the airbag module 22 and the module cover 30 having the same or more than the physical properties are provided. Inflation of the airbag cushion 22 'is prevented, and when the airbag cushion 22' is deployed toward the deployment guide groove 20, the deployment guide pieces 31a and 31b integrally formed at the outlet of the module cover 30. The airbag cushion 22 'is well deployed to the front side of the side bolster 11 by being guided precisely in the direction of the sewing portion 14 by the < RTI ID = 0.0 >

그리고 본 발명은 종래 측면 표피재(13)의 내면에 적층하던 내피재(14)와, 에어백 모듈(22)을 넣던 모듈 커버(23)를 제거하고 에어백 모듈(22)을 상기 측면 표피재(13)와 그 물성치가 동등하거나 동등 이상의 물성치를 가진 모듈 커버(30)에 넣음으로써 구조가 단순화되어 원가를 절감할 수 있는 것이다.In addition, the present invention removes the inner skin material 14 and the module cover 23 into which the air bag module 22 is placed, and the air bag module 22 is removed from the side skin material 13. ) And the physical properties of the module cover 30 having the same or more than the equivalent physical properties to simplify the structure can be reduced cost.
