본 발명은 에어백의 결합부 재봉방법에 관한 것으로, 더욱 상세하게는 고정브라켓과 체결되는 결합부의 재봉방법을 개선시킨 에어백의 결합부 재봉방법에 관한 것이다.The present invention relates to a method of sewing the coupling portion of the airbag, and more particularly, to a coupling portion sewing method of the airbag improved the sewing method of the coupling portion is fastened to the fixing bracket.

일반적으로 차량에는 충돌 및 추돌 사고시에 운전자와 탑승자를 안전하게 보호하기 위한 에어백 어셈블리가 장착되어 있어, 차량이 일정한 속도 이상으로 주행하던 중에 정면 또는 측면 충돌하게 되면, 에어백 시스템의 작동에 따라 에어백이 팽창되면서 탑승자가 차체에 직접적으로 부딪히는 것을 막아 인명 피해를 최소화한다. In general, the vehicle is equipped with an airbag assembly to protect the driver and passengers in the event of a collision and a collision accident, if the front or side collision while the vehicle is traveling at a certain speed, the airbag is inflated according to the operation of the airbag system Minimizes human injury by preventing passengers from directly hitting the body.

특히 운전석용 에어백 어셈블리는, 도 1에 도시된 바와 같이, 전자제어유닛(ECU)에서 전달되는 신호에 따라 가스를 방출하는 인플레이터(inflater)(300)가 장착된 케이지(400)와, 이 케이지(400)와 결합되며 혼(horn)을 작동시키는 마운팅 어셈블리(500)와, 상기 마운팅 어셈블리(500)에 결합되는 고정브라켓(200)이 내부에 구비되어, 소정의 외부커버(600) 내에 접힌 상태로 내장되는 에어백(100)으로 구성된다. In particular, the driver's seat airbag assembly, as shown in Figure 1, the cage 400 is equipped with an inflator (300) for discharging gas in accordance with the signal transmitted from the electronic control unit (ECU), and the cage ( 400 is coupled to the mounting assembly 500 to operate the horn (horn) and the fixing bracket 200 coupled to the mounting assembly 500 is provided therein, in a state folded in a predetermined outer cover 600 It is composed of a built-in airbag (100).

여기서, 상기 에어백(100)은, 도 2에 도시된 바와 같이, 일측에 통공(24)이 형성되고 상기 통공(24)의 외측에 다수개의 결합공(20)이 형성된 결합부(2)가 구비되며, 상기 통공(4)을 통해서 고정브라켓(200)을 삽입한 후 볼트(206)를 결합공(20)과 외부커버(600)의 고정판(610)을 통과해서 돌출시킨 다음 마운팅 어셈블리(500)를 체결시킴으로써 결합을 완료하게 된다.Here, the airbag 100, as shown in Figure 2, the through hole 24 is formed on one side and the coupling portion 2 formed with a plurality of coupling holes 20 on the outside of the through hole 24 is provided After inserting the fixing bracket 200 through the through hole 4, the bolt 206 protrudes through the fixing plate 610 of the coupling hole 20 and the outer cover 600, and then the mounting assembly 500. The coupling is completed by fastening.

따라서, 인플레이터(300)로부터 방출된 가스가 상기 통공(24)으로 주입됨으로써 에어백(100)이 팽창되어 외부커버(600)가 개방되면서 전개되는데, 이때 상기 결합부(2)가 고정브라켓(200)과 고정판(610)의 사이에 고정되어 있으므로 에어백(100)이 이탈되지 않도록 붙잡아주게 된다.Therefore, the gas discharged from the inflator 300 is injected into the through hole 24, thereby expanding the airbag 100 to open the outer cover 600. In this case, the coupling part 2 is fixed to the bracket 200. Since it is fixed between the fixing plate 610 and to hold the airbag 100 so as not to be separated.

종래에는 상기 결합부(2)를 형성하기 위해 섬유소재를 다수로 적층시켜서 강도를 보강하고, 도 2에서와 같이 통공(24)의 외측을 둘러서 재봉하여 1차 재봉부(21')를 형성하고, 상기 결합공(20)의 외측으로 둘러서 재봉하여 2차 재봉부(22') 를 형성한다.Conventionally, the fiber material is laminated to form a plurality of coupling parts 2 to reinforce the strength, and as shown in FIG. 2, the outer part of the through hole 24 is sewn to form a primary sewing part 21 ′. , And sewn around the outer side of the coupling hole 20 to form a secondary sewing part 22 '.

그런데, 이러한 재봉방법은 시간이 많이 소요될 뿐 아니라, 에어백이 팽창되었을 때 강한 인장력을 받게되는 결합공에 대한 보강효과가 없어 결합공이 파열되는 문제점이 발생되었다.By the way, the sewing method is not only time-consuming, but there is a problem that the coupling hole is broken because there is no reinforcing effect on the coupling hole that receives a strong tensile force when the air bag is inflated.

본 발명은 상기한 종래 기술을 해소하기 위해 안출된 것으로, 통공 및 결합공을 포함하여 1차로 재봉한 후 연속하여 각 결합공을 둘러서 2차로 재봉함으로써 결합공을 보강할 수 있어 파손을 방지할 수 있고, 재봉공정을 단축시킬 수 있도록 한 에어백의 결합부 재봉방법을 제공하는데 그 목적이 있다.The present invention has been made in order to solve the above-described prior art, it is possible to reinforce the coupling hole by sewing the secondary by surrounding each coupling hole in succession after the first sewing including the through hole and the coupling hole can prevent damage In addition, the object of the present invention is to provide a method of sewing the combined portion of the airbag to shorten the sewing process.

상기한 목적을 달성하기 위해 본 발명은,The present invention to achieve the above object,

일측에 통공이 형성되고, 그 외측에 다수개의 결합공이 형성된 결합부를 갖는 에어백에 있어서, 상기 결합공의 둘레에 1차 재봉부를 형성하고, 상기 1차 재봉부를 포함하며 그 외주에 접하도록 2차 재봉부를 형성하는 것을 특징으로 한다.A through-hole is formed on one side, the airbag having a coupling portion formed with a plurality of coupling holes on the outside, forming a primary sewing portion around the coupling hole, including the primary sewing portion and the secondary sewing to contact the outer periphery It is characterized by forming a part.

이하 본 발명의 바람직한 실시예를 첨부된 도 3을 토대로 상세하게 설명하는데, 종래 기술과 동일한 구성에 대해서는 도 1 및 도 2에서 사용한 구성부호를 사용한다.Hereinafter, a preferred embodiment of the present invention will be described in detail with reference to the accompanying FIG. 3, and the same reference numerals are used for the same components as those in the prior art.

상기 결합부(2)를 형성하기 위해 섬유소재를 여러겹으로 덧대고, 적당한 위치에 소정의 통공(24)을 형성시키고, 이 통공(24)의 외측에 등간격으로 다수개의 결합공(20)을 형성시킨 다음 상기 결합공(20)들의 외측을 둘러서 재봉하여 1차 재 봉부(21)를 형성하고, 계속해서 각 결합공(20)마다 그 둘레를 재봉하여 2차 재봉부(22)를 형성한다.In order to form the coupling part 2, the fiber material is padded in several layers, and a predetermined through hole 24 is formed at an appropriate position, and the plurality of coupling holes 20 are disposed at equal intervals on the outside of the through hole 24. And then sew around the outside of the coupling holes 20 to form a primary sewing portion 21, and then sewn the circumference for each coupling hole 20 to form a secondary sewing portion 22. do.

이렇게 결합부(2)가 완성되면 상기 통공(24)을 통해서 고정브라켓(200)을 삽입한 후 볼트(206)를 상기 결합공(20) 및 외부커버(600)의 고정판(610)을 통과시킨 다음 마운팅 어셈블리(500)에 체결시킨다.When the coupling part 2 is completed, the fixing bracket 200 is inserted through the through hole 24, and then the bolt 206 is passed through the fixing plate 610 of the coupling hole 20 and the outer cover 600. Next, to the mounting assembly 500.

따라서, 에어백(100)이 팽창되면서 외부로 당겨지는 인장력이 발생되면, 상대적으로 취약한 결합공(20)이 강하게 당겨지게 되지만, 본 발명은 각 결합공(20)마다 2차 재봉부(22)가 형성되어 있어 인장력에 견딜수 있는 보강력이 제공될 수 있다.Therefore, when the tension force to be pulled to the outside while the airbag 100 is inflated, the relatively weak coupling hole 20 is pulled strongly, the present invention is the secondary sewing unit 22 for each coupling hole 20 It can be formed to provide a reinforcement to withstand the tensile force.

이상에서 살펴본 바와 같이, 본 발명에 따른 에어백의 결합부 재봉방법은 통공 및 결합공을 포함하여 1차로 재봉한 후 연속하여 각 결합공의 둘레를 2차로 재봉함으로써 결합공의 강도를 보강할 수 있어 에어백의 파손을 방지할 수 있고, 재봉공정이 단축될 수 있는 장점이 제공된다.As described above, the method of sewing the coupling portion of the airbag according to the present invention can be reinforcement of the strength of the coupling hole by sewing the circumference of each coupling hole in succession after sewing the first including the through-hole and coupling hole The advantage of being able to prevent breakage of the airbag and shortening the sewing process is provided.
