Abstract

PURPOSE: Structure for installing an airbag of a front passenger's seat is provided to improve the external appearance by integrating an airbag cover with a crash pad and to avoid the injury on an occupant in a front passenger's seat when an airbag is exploded by removing the contaminants in a gap between the airbag cover and the crash pad. CONSTITUTION: An airbag installation bracket(10) is attached on a cowl cross member(11). A boss portion(10a) and a connecting portion(10b) are formed on the airbag installation bracket. An airbag body(100) including an airbag(20) is fitted in the boss portion and fixed on the airbag installation bracket via the connecting portion. The airbag body includes a support bracket(110). The support bracket is connected with an attachment guide bracket(120) via a bolt. The attachment guide bracket is attached to a fixing bracket(130) formed below a crash pad(200). The fixing bracket is connected with a connecting portion(200a) of the crash pad. For smooth destruction of the crash pad, a thin film portion(210) is formed around the crash pad. The airbag is exploded after the crash pad is destructed. Therefore, an occupant of a front passenger's seat is protected.

이하, 첨부된 도면을 참조로 하여, 본 발명의 실시예를 상세히 설명하면 다음과 같다.Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

도 2는 본 발명의 바람직한 실시예에 의한 자동차용 조수석 에어백 장착 구조물을 개략적으로 도시한 단면도이다.Figure 2 is a schematic cross-sectional view showing a passenger seat airbag mounting structure for a vehicle according to a preferred embodiment of the present invention.

도 2에서 도시된 바와 같이, 종래와 마찬가지로 에어백 설치용 브라켓(10)은 카울 크로스 부재(11)에 부착된다. 이 에어백 설치용 브라켓(10) 상에는 보스부(10a)와 체결부(10b)가 구성되어 있다. 에어백(20)을 포함한 에어백 본체부(100)는 보스부(10a)에 끼워지고, 체결부(10b)를 통해 에어백 설치 브라켓(10)에 고정된다. 여기서, 보스부(10a)의 역할을 에어백 본체부(100)가 장착될 때, 장착 위치의 기준을 제공하는 역할을 하며, 체결부(10b)는 에어백 본체부(100)를 에어백 설치용 브라켓 상(10)에 고정하는 역할을 한다. 이와 같은 에어백 본체부(100)는 지지브라켓(110)이 구비되어 있는데, 이 지지브라켓(110)은 에어백 본체부(100)와 일체로 구성된다. 지지브라켓(110)은 부착 안내 브라켓(120)과 바람직하게 볼트로 연결되며, 이 부착 안내 브라켓(120)은 크래쉬 패드(200)의 하부 밑에 제공된 고정 브라켓(130)에 부착되며, 이 고정 브라켓(130)은 크래쉬 패드(200)의 하부에 형성되어 있는 체결부(200a)에 바람직하게 볼트로 체결된다. 여기서 크래쉬 패드(200)는 주행시 한눈에 운행정보를 파악할 수 있도록 각종 계기들이 운전자 중심으로 통상 폴리우레탄 재질의 횡방향으로 배치되어 있는 것을 말한다.As shown in FIG. 2, the airbag mounting bracket 10 is attached to the cowl cross member 11 as in the related art. The boss part 10a and the fastening part 10b are comprised on this airbag mounting bracket 10. As shown in FIG. The airbag main body 100 including the airbag 20 is fitted to the boss portion 10a and fixed to the airbag mounting bracket 10 through the fastening portion 10b. Here, when the airbag body portion 100 serves as the boss portion 10a, it serves to provide a reference of the mounting position, and the fastening portion 10b forms the airbag body portion 100 on the airbag installation bracket ( 10) to fix the role. The airbag main body 100 is provided with a support bracket 110, the support bracket 110 is configured integrally with the airbag body 100. The support bracket 110 is preferably bolted to the attachment guide bracket 120, and the attachment guide bracket 120 is attached to the fixing bracket 130 provided under the crash pad 200, and the fixing bracket ( 130 is preferably bolted to the fastening portion 200a formed in the lower portion of the crash pad 200. Here, the crash pad 200 refers to a variety of instruments are arranged in the transverse direction of the usual polyurethane material around the driver so as to grasp the driving information at a glance when running.

또한, 크래쉬 패드(200)은 에어백(20)이 폭발 할 때, 원활히, 크래쉬 패드(200)를 파괴하여, 폭발할 수 있도록 에어백 본체부가(100) 설치되는 곳 둘레로 박막부(210)가 형성된다.In addition, the crash pad 200 is formed when the airbag 20 is exploded, the thin film portion 210 is formed around the place where the airbag body portion 100 is installed so that the crash pad 200 can be exploded and exploded. do.

위와 같은 구조로, 에어백 본체부(100)의 각 모서리 부근은 지지브라켓(110)과, 부착 안내 브라켓(120)과 고정 브라켓(300)을 통해 크래쉬 패드(200)에 고정되지만, 모서리를 제외한 에어백 본체부(100)는 크래쉬 패드(200)의 바로 하단에 위치되므로, 에어백(20)이 폭발되면, 에어백(20)은 크래쉬 패드(200)의 박막부(210)를 파괴한 다음 부풀려진다.With the above structure, the vicinity of each corner of the airbag body portion 100 is fixed to the crash pad 200 through the support bracket 110, the attachment guide bracket 120 and the fixing bracket 300, but the airbag except the corner Since the main body 100 is located directly below the crash pad 200, when the airbag 20 is exploded, the airbag 20 is inflated after destroying the thin film unit 210 of the crash pad 200.

이상과 같은 본 발명에 따른 조수석용 에어백 장착 구조물은 에어백 덮개와 크래쉬 패드가 일체로 형성되므로 외관미가 향상되고, 또한 종래의 틈새 또는 단차부에 낄 수 있었던 이물질이 제거되므로, 에어백이 폭발할 때, 이물질로 인하여 조수석 탑승자의 부상을 막을 수 있는 장점이 있다.The passenger seat airbag mounting structure according to the present invention as described above, since the airbag cover and the crash pad are integrally formed, the appearance is improved, and foreign matters that may have been trapped in the conventional gap or step are removed, and thus, when the airbag explodes, There is an advantage that can prevent the injury of the passenger occupant due to foreign matter.
