Description
본 고안은 에어백 하우징 체결구조에 관한 것으로 더욱 상세하게는 에어백 하우징의 체결부 외주연에 숫나사부를 형성하고 이와 체결되는 스티어링 휠 허브(Steering wheel hub)의 내주연에 암나사부를 형성하여 에어백 하우징이 스티어링 휠 허브에 상호 나사결합되는 에어백 하우징 체결구조에 관한 것이다.The present invention relates to an airbag housing fastening structure. More specifically, a male screw part is formed on an outer circumference of a fastening part of an airbag housing, and a female thread part is formed on an inner circumference of a steering wheel hub which is fastened thereto. An airbag housing fastening structure that is mutually screwed to a hub.
일반적으로 자동차의 성능을 가늠하는 기준이 단순한 차량의 성능대비보다는 점차 사고 발생시 탑승자를 얼마나 보호할 수 있느냐 하는 자동차의 안전도로 기준이 바뀌고 있는 추세이다.In general, the standard for measuring the performance of the car is changing the standard of safety of the car, how much can protect the occupant in the event of an accident rather than the performance of the vehicle.
이러한 자동차의 안전도를 향상시키는 장치 가운데 대표적인 예로 에어백을 들 수 있는데 에어백은 운전석의 스티어링 휠 상부의 허브나 조수석의 인스트루먼트 패널 내측에 에어백 하우징이 장착되고 내부에 에어백과 이를 작동시키는 에어백 센서가 설치되어 차량의 정면충돌시 충돌관성의 정도를 감지한 에어백 센서에 의하여 인플레이터(Inflater)에 전원이 통전되어 순간적으로 에어백내에 압축가스가 주입되어 에어백을 부풀리므로써 충돌관성에 의하여 전방으로 쏠리는 탑승자의 신체를 보호하도록 하는 안전장치이다.An example of such a device that improves the safety of the vehicle is an airbag, which is equipped with an airbag housing inside the hub of the steering wheel of the driver's seat or the instrument panel of the passenger seat and an airbag sensor for operating the airbag and the inside of the vehicle. Power is supplied to the inflater by the airbag sensor that detects the degree of collision inertia during frontal collision.The compressed gas is instantaneously injected into the airbag to inflate the airbag to protect the occupant's body that is pushed forward by the collision inertia. It is a safety device to make sure.
상기와 같은 종래의 에어백은 도 1 에서 도시된 바와같이 스티어링 휠(1) 중앙에 형성되는 스티어링 휠 허브(3)의 안착홈(5)에 에어백 하우징(7)의 하측 체결 브라켓(9)이 삽입되고 상기 안착홈(5)과의 체결 브라켓(9)의 결합부 외측에 볼트(11)가 삽입되어 스티어링 휠 허브(3)에 에어백 하우징(7)이 체결된다. 이러한 에어백 하우징(7)의 내측에는 에어백(13)이 형성되고 그 일측에는 에어를 주입하는 인플레이터(15)와 이에 전원을 공급하는 전원선(17)이 형성된다.The conventional airbag as described above is inserted into the lower fastening bracket (9) of the airbag housing (7) in the seating groove (5) of the steering wheel hub (3) formed in the center of the steering wheel (1) as shown in FIG. The bolt 11 is inserted into the outer side of the coupling portion 9 of the fastening bracket 9 with the seating groove 5 to fasten the airbag housing 7 to the steering wheel hub 3. The airbag 13 is formed inside the airbag housing 7, and an inflator 15 for injecting air and a power line 17 for supplying power thereto are formed at one side thereof.
그러나 종래의 스티어링 휠 허브의 안착홈에 에어백 하우징의 체결 브라켓이 삽입되어 볼팅되는 체결구조에서는 스티어링 휠이 엔진의 진동에 장기간 노출되면 이에 의하여 볼트가 느슨해져 상호 체결부위가 이격되므로써 안착홈과 체결 브라켓이 맞부딪쳐 소음이 발생하는 문제점이 있어왔다.However, in a fastening structure in which a fastening bracket of an airbag housing is inserted into a seating groove of a conventional steering wheel hub and bolted, when the steering wheel is exposed to vibration of the engine for a long time, the bolt is loosened and the fastening parts are spaced apart so that the seating groove and the fastening bracket are separated. There has been a problem in that noise is encountered.
또한 안착홈에 에어백 하우징을 체결하는 작업시 스티어링 휠의 안착홈 측면에서 볼트를 삽입하여 탈착하여야 하므로 조립성과 작업성이 저하되는 또 다른 문제점이 있어왔다.In addition, there is another problem that the assembly and workability is deteriorated because the bolt must be inserted and detached from the seating groove side of the steering wheel when the airbag housing is fastened to the seating groove.
본 고안은 이와같은 종래의 문제점을 해결하기 위하여 안출된 것으로 스티어링 휠 허브의 안착홈 내주연에 암나사부를 형성하고 이에 삽입되는 에어백 하우징의 체결 브라켓의 외주연에는 숫나사부를 형성하여 상호 나사결합하므로써 진동에 의한 안착홈과 체결 브라켓의 이격을 미연에 방지하는 것은 물론 스티어링 휠 허브의 상측에서 에어백 하우징을 나사결합하므로써 조립성 및 작업성을 향상시키는 에어백 하우징 체결구조를 제공하는데 그 목적이 있다.The present invention was devised to solve such a conventional problem, and the female screw portion was formed on the inner circumference of the seating groove of the steering wheel hub and the male screw portion was formed on the outer circumference of the fastening bracket of the airbag housing inserted therein, thereby mutually screwing together. It is an object of the present invention to provide an airbag housing fastening structure that improves assembling and workability by screwing the airbag housing on the upper side of the steering wheel hub as well as preventing the separation between the mounting groove and the fastening bracket by the above.
상기와 같은 목적을 달성하기 위해서 본 고안은 내측에 에어백을 형성하고 일측단에 전원선과 연결되는 인플레이터를 형성하며 스티어링 휠 허브의 안착홈에 체결되는 에어백 하우징에 있어서, 안착홈의 내주연에 암나사부를 형성하는 스티어링 휠 허브와, 상기 안착홈에 삽입되는 체결 브라켓의 외주연에 숫나사부를 형성하는 에어백 하우징으로 구성된다.In order to achieve the above object, the present invention forms an airbag on the inner side, forms an inflator connected to a power line at one end, and is provided in the airbag housing which is fastened to the seating groove of the steering wheel hub. The steering wheel hub to be formed, and the airbag housing forming a male screw portion on the outer circumference of the fastening bracket inserted into the seating groove.

이하에서는 첨부도면을 참조하여 본 고안의 바람직한 실시예를 상세히 설명한다.Hereinafter, with reference to the accompanying drawings will be described in detail a preferred embodiment of the present invention.
도 2는 본 고안의 에어백 하우징 체결구조를 개략적으로 도시한 요부측단면도로써 스티어링 휠(1)의 일측에 형성되는 스티어링 휠 허브(3)의 상부면에 에어백 하우징(21)이 설치되는 안착홈(23)이 형성된다. 이러한 안착홈(23)의 내주연에는 암나사부(25)가 형성되고 이에 삽입되는 에어백 하우징(21)의 체결브라켓(29) 외주연에 형성된 숫나사부(27)와 치합되면서 나사결합된다. 상기 에어백 하우징(21)의 내측에는 에어백(13)이 다단으로 접혀 설치되고 그 내측끝단에는 인플레이터(15)가 형성되어 스티어링 휠(1) 내부로 삽입된 전원선(17)과 연결된다. 즉 상기 전원선(17)은 안착홈(23)의 하측을 거쳐 인플레이터(15)에 연결되어 전원을 공급한다.Figure 2 is a main portion side cross-sectional view schematically showing the airbag housing fastening structure of the present invention seating groove in which the airbag housing 21 is installed on the upper surface of the steering wheel hub (3) formed on one side of the steering wheel ( 23) is formed. An internal thread portion 25 is formed on the inner circumference of the seating groove 23 and is screwed while engaged with the male thread portion 27 formed on the outer circumference of the fastening bracket 29 of the airbag housing 21 inserted therein. Inside the airbag housing 21, the airbag 13 is installed to be folded in multiple stages, and an inflator 15 is formed at an inner end thereof to be connected to a power line 17 inserted into the steering wheel 1. That is, the power line 17 is connected to the inflator 15 through the lower side of the mounting groove 23 to supply power.
상기와 같이 구성되는 본 고안의 작용효과를 상세히 설명하면 다음과 같다.If described in detail the effects of the present invention is configured as described above.
도면을 참조하면 에어백(13)이 내장된 에어백 하우징(21)을 스티어링 휠 허브(3)에 장착하기 위해서는 상기 에어백 하우징(21)의 하측에 일체로 형성되는 체결 브라켓(29)의 외주연에 치설된 숫나사부(27)를 스티어링 휠 허브(3)의 안착홈(23) 내주연에 형성된 암나사부(25)에 치합하여 상호 나사결합하므로써 고정한다.Referring to the drawings, in order to mount the airbag housing 21 with the built-in airbag 13 to the steering wheel hub 3, it is installed on the outer circumference of the fastening bracket 29 integrally formed under the airbag housing 21. The male screw portion 27 is engaged with the female screw portion 25 formed at the inner circumference of the seating groove 23 of the steering wheel hub 3 and screwed together.
이상에서 설명한 바와같이 본 고안은 스티어링 휠 허브의 안착홈 내주연에 암나사부를 형성하고 이에 삽입되는 에어백 하우징의 체결 브라켓의 외주연에는 숫나사부를 형성하여 상호 나사결합하므로써 진동에 의한 안착홈과 체결 브라켓의 이격을 미연에 방지하는 것은 물론 스티어링 휠 허브의 상측에서 에어백 하우징을 나사결합하므로써 조립성 및 작업성을 향상시키는 효과가 있다.As described above, the present invention forms a female thread on the inner circumference of the seating groove of the steering wheel hub, and a male thread is formed on the outer circumference of the fastening bracket of the airbag housing to be inserted therein so that the threaded coupling between the seating recess and the fastening bracket is caused by vibration. In addition to preventing the separation in advance, as well as screwing the airbag housing on the upper side of the steering wheel hub has an effect of improving the assembly and workability.
