Description

조수석 에어백의 쿠션{cushion of passenger air bag} Cushion of passenger air bag

본 발명은 조수석 에어백에 관한 것으로서, 보다 상세하게는 조수석 에어백의 쿠션에 관한 것이다.The present invention relates to a passenger airbag, and more particularly to a cushion of a passenger airbag.

에어백은 차량의 충돌 사고시 공기 또는 가스가 급속 주입되어 부풀어 오름으로써 탑승자의 상부 몸체를 보호하기 위한 보호 장구로서, 운전자의 보호를 위한 운전석 에어백과 조수석 탑승자의 보호를 위한 조수석 에어백으로 구분된다. 운전석 에어백은 일반적으로 핸들의 내부에 장착되어 있으며, 조수석 에어백은 조수석 앞쪽의 크래쉬 패드에 설치되어 있다.The airbag is a protective device for protecting the upper body of the occupant by inflating air or gas inflated during a crash of the vehicle, and is divided into a driver's seat airbag for the driver's protection and a passenger seat airbag for the passenger's passenger. The driver's seat airbag is typically mounted inside the steering wheel, and the passenger seat airbag is mounted on the crash pad in front of the passenger seat.

도1은 일반적인 조수석 에어백을 나타낸 개략 단면도이고, 도2는 일반적인 조수석 에어백의 쿠션이 접힌 상태를 나타내는 단면도이다. 도1에 도시한 바와 같은 조수석 에어백(1)은 글로브 박스 상측의 크래쉬 패드에 설치되는데, 하우징(2)의 상측에는 쿠션(4)이 결합되고, 하우징(2)의 하측에는 인플레이터(6)가 내장된 구조이다. 상기 쿠션(4)은 도2에 도시한 바와 같이 접혀져서 쿠션 커버(8)에 의해 이탈하지 않게 되어 있다. 상기 쿠션 커버(8)에는 에어백이 작동할 시 찢어지기 쉽도록 도시하지 않은 티어 라인(tear line)이 에어백의 길이방향을 따라 형성되어 있다. 1 is a schematic cross-sectional view showing a general passenger airbag, Figure 2 is a cross-sectional view showing a folded state of the general passenger airbag. The passenger seat airbag 1 as shown in FIG. 1 is installed in a crash pad on the upper side of the glove box. A cushion 4 is coupled to the upper side of the housing 2, and an inflator 6 is disposed below the housing 2. It is a built-in structure. The cushion 4 is folded as shown in FIG. 2 so as not to be separated by the cushion cover 8. The cushion cover 8 has a tear line (not shown) formed along the longitudinal direction of the airbag so as to be easily torn when the airbag operates.

이와 같이 구성된 조수석 에어백(1)은 차량 충돌시 ECU로부터 에어백 작동 신호를 받으면 에어백(1)의 인플레이터(6)에 점화가 이루어져 폭발하면서 쿠션(4)이 부풀게 되고, 이때 상기 쿠션(4)의 팽창력에 의해 쿠션 커버(8)가 티어 라인을 따라 갈라지면서 상기 쿠션(4)은 조수석의 전방으로 크게 부풀게 된다.When the passenger seat airbag 1 configured as described above receives an airbag operation signal from the ECU during a vehicle crash, the inflator 6 of the airbag 1 is ignited and exploded, causing the cushion 4 to swell. In this case, the inflating force of the cushion 4 is increased. As the cushion cover 8 splits along the tier line, the cushion 4 is greatly inflated toward the front of the passenger seat.

도3은 종래 조주석 에어백의 쿠션이 전개된 상태의 형상을 나타내는 단면도인데, 종래 쿠션(14)은 전개상태에서 상기 하우징에 고정된 고정부(14a)와, 탑승자에 닿아 상해를 보호하는 보호부(14b)로 이루어져 있다.Figure 3 is a cross-sectional view showing the shape of the conventional cushion seat airbag deployment state, the conventional cushion 14 is a fixed portion (14a) fixed to the housing in the deployed state, and a protective portion to protect the injury to the occupant (14b).

그런데, 이와 같이 구성된 종래의 조수석 에어백에서는 쿠션(14)이 앞으로 접혀져 있고 별도의 구조물이 없이 쿠션 전개시 승객 쪽으로 쿠션이 향하도록 되어 있으므로, 비정상적으로 착좌된 승객에게는 치명적 상해가 가해질 수 있다는 문제점이 있었다.However, in the conventional passenger seat airbag configured as described above, since the cushion 14 is folded forward and the cushion is directed toward the passenger when the cushion is deployed without a separate structure, a fatal injury may be inflicted on an abnormally seated passenger. .

따라서, 본 발명은 상기 문제점을 해결하기 위해 이루어진 것으로서, 본 발명의 목적은 쿠션의 전개시 그 전개방향을 분산하므로써 비정상적으로 착좌된 승객의 상해를 방지하는 조수석 에어백의 쿠션을 제공하는 데 있다.Accordingly, the present invention has been made to solve the above problems, and an object of the present invention is to provide a cushion of a passenger seat airbag that prevents injuries of passengers seated abnormally by dispersing its deployment direction when the cushion is deployed.

상기 목적을 달성하기 위한 본 발명에 따른 조수석 에어백의 쿠션은, 하우징의 상측에 접혀져 결합되며 쿠션커버에 의해 감싸지는 쿠션을 가지는 조수석 에어백에 있어서, 상기 쿠션은, 전개상태에서 상기 하우징에 고정되는 고정부와, 탑승자에 닿아 상해를 보호하는 보호부로 이루어지되, 상기 보호부에는 전개시 전개방향을 변화시키도록 쿠션의 내측방향으로 요입되는 요입부가 형성되는 한편 상기 요입부의 양측은 이 요입부를 유지시키는 외부 띠에 의해 이어져 있는 것을 특징으로 한다.Cushion of the passenger seat airbag according to the present invention for achieving the above object, in the passenger seat airbag having a cushion folded and coupled to the upper side of the housing and wrapped by a cushion cover, the cushion is fixed to the housing in a deployed state Consists of the government and the protection unit to protect the injury in contact with the occupant, the protection unit is formed with a concave indented in the inner direction of the cushion so as to change the deployment direction during deployment, while both sides of the concave portion is the outer to maintain this indentation It is characterized by being connected by a belt.

상기 외부 띠의 중간에는 쿠션의 전개시 용이하게 끊어지도록 티어 라인이 형성되어 있다.A tier line is formed in the middle of the outer band so as to easily break when the cushion is deployed.

이하, 첨부된 도면을 참조하여 본 발명의 실시예를 상세히 설명한다.Hereinafter, with reference to the accompanying drawings will be described an embodiment of the present invention;

본 발명의 쿠션이 결합되는 조수석 에어백의 전체적 구조 및 쿠션이 접혀져 결합되는 형상은 도1 및 도2에 도시한 바와 같으므로 상세한 설명을 생략한다.The overall structure of the passenger seat airbag to which the cushion of the present invention is coupled and the shape of the cushion to which the cushion is folded are as shown in FIGS. 1 and 2, and thus, detailed description thereof will be omitted.

도4는 본 발명에 의한 조수석 에어백의 쿠션이 반 전개된 상태의 형상을 나타내는 단면도인데, 쿠션은 하우징의 상측에 접혀져 결합되며 쿠션커버에 의해 감싸지게 된다. Figure 4 is a cross-sectional view showing the shape of the cushion of the passenger seat airbag according to the present invention in a half-expanded state, the cushion is folded and coupled to the upper side of the housing is wrapped by the cushion cover.

도4에 도시한 바와 같이 본 발명에 의한 조수석 에어백의 쿠션(24)은, 전개상태에서 도1에 도시한 바와 같은 상기 하우징에 고정되는 고정부(24a)와, 탑승자에 닿아 상해를 보호하는 보호부(24b)로 이루어진다.As shown in Fig. 4, the cushion 24 of the passenger seat airbag according to the present invention has a fixed portion 24a fixed to the housing as shown in Fig. 1 in a deployed state, and protects the occupant from injury. It consists of a part 24b.

상기 보호부(24b)에는 전개시 전개방향을 변화시키도록 쿠션의 내측방향으로 요입되는 요입부(24c)가 형성되는 한편 상기 요입부(24c)의 양측은 이 요입부를 유지시키는 외부 띠(26)에 의해 이어져 있다.The protection part 24b is formed with a concave part 24c concaved in the inward direction of the cushion so as to change the deployment direction at the time of deployment, while both sides of the concave part 24c hold an outer strip 26 for retaining the concave part. Followed by

상기 외부 띠(26)의 중간에는 쿠션의 전개시 용이하게 끊어지도록 티어 라인(26a : tear line)이 형성되어 있다.A tear line 26a is formed in the middle of the outer strip 26 so as to easily break when the cushion is deployed.

상기 외부 띠(26)의 양단은 상기 요입부(24c)의 양측면에 재봉되어 있다. 도면에서 부호 26b, 26c는 재봉선을 나타내고 있다.Both ends of the outer strip 26 are sewn on both sides of the concave inlet 24c. In the drawings, reference numerals 26b and 26c denote sewing lines.

이와같이 구성된 본 발명에 의한 쿠션을 가진 조수석 에어백에서, 차량 충돌시 ECU로부터 에어백 작동 신호를 받으면 에어백의 인플레이터에 점화가 이루어져 폭발하면서 쿠션(24)이 부풀게 되고, 상기 쿠션(24)의 팽창력에 의해 쿠션 커버(도2에 도시)가 도시하지 않은 티어 라인을 따라 갈라지게 되고, 쿠션(24)이 도4에서 도시한 바와 같은 상태로 팽창하게 된다. In the passenger seat airbag having a cushion according to the present invention configured as described above, upon receiving an airbag operation signal from the ECU during a vehicle crash, the inflator of the airbag ignites and explodes, causing the cushion 24 to inflate, and the cushion 24 is inflated by the expansion force of the cushion 24. The cover (shown in FIG. 2) splits along the tier line, not shown, and the cushion 24 expands to the state shown in FIG.

이 상태에서 외부 띠(26)가 쿠션의 전개를 일시적으로 방해하게 되면서 쿠션(24)을 잡아주게 되는데, 이와 같이 외부 띠(26)가 쿠션을 잡아주는 동안 쿠션(24)이 옆으로 전개되면서 외부 띠(26)가 티어 라인(26a)에서 끊어지게 되며, 요입부(24c)가 펴지면서 쿠션(24)은 더욱 부풀어 완전히 전개된다. In this state, the outer belt 26 temporarily holds the cushion 24 while interfering with the cushion's development. As such, while the outer belt 26 holds the cushion, the cushion 24 unfolds to the side and the outside The band 26 is cut off at the tier line 26a, and the cushion 24 is further inflated and fully deployed as the recess 24c is extended.

즉, 상기 외부 띠(26)는 쿠션의 전개시 일정한 압력까지 유지해 주면서 쿠션의 전개방향을 좌, 우로 향하게 진행방향을 분산해 주게 된다. 따라서, 쿠션의 전개방향이 분산되므로 비정상적으로 착좌된 승객의 상해를 방지할 수 있는 것이다.That is, the outer belt 26 distributes the advancing direction so that the cushion deployment direction is left and right while maintaining a constant pressure when the cushion is deployed. Therefore, since the deployment direction of the cushion is dispersed, it is possible to prevent injury of passengers seated abnormally.

본 발명에 의한 조수석 에어백 쿠션에 의하면, 외부 띠가 쿠션의 전개시 일정한 압력까지 유지해 주면서 쿠션의 전개방향을 좌, 우로 향하게 진행방향을 분산하므로써 비정상적으로 착좌된 승객의 상해를 방지하는 효과가 있다.According to the passenger seat airbag cushion according to the present invention, while the outer strap is maintained to a certain pressure during the deployment of the cushion, by dispersing the direction of movement of the cushion toward the left and right, there is an effect of preventing injuries of abnormally seated passengers.
