Abstract

PURPOSE: A structure is provided to prevent the breakage of a windshield and a safety door in case an airbag established in the receiving portion is open-popped up and that a safety door covering a receiving portion is open knocking against a windshield in a vehicle collision. CONSTITUTION: A receiving portion(130) having a bleed groove for an established airbag to bleed is formed on a front part of an instrument panel(110). A safety door(140) opening the bleed groove is rotationally hinge-combined on the upper part of the receiving portion(130). A pair of support brackets(150) having a guide hole(151) is connected to the inner upper side of the receiving portion(130). In the inside safety door(140), a pair of stopper bars(160) not only sliding by inserting into the guide hole(151) of the support bracket(150) but also forming a hanging protrusion(161) hung to the guide hole(151) are connected. When a vehicle collides, the airbag(120) of the receiving portion(130) starts to deploy and then the deployed airbag pushes and enables the safety door to rotate. The airbag popping out from the receiving portion(130) is completely deployed to protect an occupant's face and chest leaned toward the windshield(170) because of inertia. The process of being popped up from the receiving portion(130) and being deployed of the airbag develops as the following. The stopper bar(160) fixedly connected to the inside safety door(140) slides along with the support bracket(150) and the guide hole(151) so that the safety door is pushed by the airbag(120) and conducts hinge-centered rotation in a specific section. When the hanging protrusion(161) formed on the end portion of the stopper bar(160) is hung to the end portion of the guide hole(151) of the support bracket(150), the rotation of the safety door(140) is stopped and the opening of the safety door(140) is ended. Therefore, the collision between the safety door(140) and the windshield(170) is stopped by the stopper bar(160) beforehand.

도 2는 본 발명의 실시예에 의한 자동차 에어백 수납부의 안전도어 개폐구조를 나타낸 단면도이고, 도 3은 본 발명인 자동차 에어백 수납부의 안전도어 개폐구조의 작동 상태도이며, 도 4는 본 발명인 자동차 에어백 수납부의 안전도어 개폐구조를 나타낸 사시도이다.Figure 2 is a cross-sectional view showing a safety door opening and closing structure of the vehicle airbag housing according to an embodiment of the present invention, Figure 3 is an operational state diagram of the safety door opening and closing structure of the vehicle airbag housing of the present invention, Figure 4 is an automobile airbag of the present invention A perspective view showing the safety door opening and closing structure of the housing.

도시한 바와 같이 본 발명의 실시예에 의한 자동차 에어백 수납부의 안전도어 개폐구조는 인스트러먼트패널(110)의 상단에 에어백(120)이 설치되어 취출되도록 취출홈(131)을 갖는 수납부(130)가 형성되고, 상기 수납부(130)의 상측에는 취출홈(131)을 개폐하는 안전도어(140)가 회동 가능하게 힌지(141) 결합되며, 상기 수납부(130)의 상측 내면에는 안내공(151)을 갖는 지지브라켓(150) 한쌍이 결합되고, 상기 안전도어(140)의 내측면에는 상기 지지브라켓(150)의 안내공(151)에 삽입되어 슬라이드됨과 아울러 단부에 상기 안내공(151)에 걸리는 걸림돌기(161)가 형성된 스토퍼바(160) 한쌍이 결합되어 구성된다.As shown, the safety door opening and closing structure of the vehicle airbag storage unit according to an embodiment of the present invention is provided with an air outlet 120 is installed on the upper end of the instrument panel 110 having a blowout groove 131 ( 130 is formed, the safety door 140 for opening and closing the take-out groove 131 is hinged 141 rotatably coupled to the upper side of the housing 130, the guide on the upper inner surface of the housing 130 A pair of support brackets 150 having a ball 151 are coupled to the inner surface of the safety door 140 and inserted into the guide holes 151 of the support bracket 150 and slide the guide holes at the ends. A pair of stopper bars 160 formed with the engaging protrusion 161 caught by the 151 is coupled to each other.

상기 안전도어(140)의 내측면에 결합된 스토퍼바(160)의 길이는 에어백(120)에 의해 밀려 회동되는 안전도어(140)가 윈드실드(170)에 닿기 이전까지 지지브라켓(150)의 안내공(151)을 따라 슬라이드 하다가 스토퍼바(160)의 걸림돌기(161)가 안내공(151) 단부에 걸릴 수 있는 길이로 한다.The length of the stopper bar 160 coupled to the inner side of the safety door 140 is pushed by the airbag 120 until the safety door 140 is touched by the windshield 170 of the support bracket 150. While sliding along the guide hole 151, the locking protrusion 161 of the stopper bar 160 has a length that can be caught by an end of the guide hole 151.

또한, 상기 지지브라켓(150)은 수납부(130)의 상측인 취출홈(131)의 양측부위에 결합하되, 상기 수납부(130)에서 튀어나오는 에어백(120)이 지지브라켓(150)에 걸리지 않고 상기 취출홈(131)을 통해 원활히 취출되도록 결합된다.In addition, the support bracket 150 is coupled to both sides of the outlet groove 131, which is the upper side of the housing 130, the air bag 120 protruding from the housing 130 is caught by the support bracket 150 It is coupled to be taken out smoothly through the take-out groove 131 without.

이와 같이 구성된 본 발명인 자동차 에어백 수납부의 안전도어 개폐구조의 작용은 다음과 같다.The operation of the safety door opening and closing structure of the vehicle airbag housing of the present invention configured as described above is as follows.

자동차가 충돌되면, 상기 수납부(130)에 설치된 에어백(120)이 펼쳐지기 시작하고, 이어 펼쳐지는 에어백(120)이 상기 안전도어(140)를 밀어 회동시키며 수납부(130)의 외부로 튀어나와 완전히 펼쳐져 충돌시 관성에 의해 윈드실드(170) 방향으로 쏠리는 탑승자의 안면 및 가슴 등을 안전하게 받쳐 보호하게 된다.When the car collides, the airbag 120 installed in the accommodating part 130 begins to unfold, and the airbag 120 which is subsequently unfolded pushes the safety door 140 to rotate and bounces out of the accommodating part 130. Completely spread out with me to protect the face and chest of the occupant secured in the direction of the windshield 170 by the inertia during the collision.

이때, 상기 안전도어(140)를 밀며 에어백(120)이 수납부(130)에서 튀어나와 펼쳐지는 과정은 도 2에 도시한 바와 같이 상기 안전도어(140)의 내측면에 고정 결합된 스토퍼바(160)가 지지브라켓(150)의 안내공(151)을 따라 슬라이드 하여 안전도어(140)가 에어백(120)에 밀리며 힌지(141)를 중심으로 소정구간 회동되다가, 스토퍼바(160)의 단부에 형성된 걸림돌기(161)가 지지브라켓(150)의 안내공(151) 단부에 걸리게되면 안전도어(140)의 회동이 정지되며 안전도어(140)의 개방이 멈추게 된다.At this time, the process of pushing the safety door 140 and the airbag 120 pops out of the receiving unit 130, the stopper bar fixedly coupled to the inner surface of the safety door 140 as shown in FIG. 160 slides along the guide hole 151 of the support bracket 150, the safety door 140 is pushed by the airbag 120 and rotated for a predetermined period around the hinge 141, the end of the stopper bar 160 When the formed locking protrusion 161 is caught by the end of the guide hole 151 of the support bracket 150, the rotation of the safety door 140 is stopped and the opening of the safety door 140 is stopped.

따라서, 안전도어(140)가 윈드실드(170)와 충돌되기 이전에 스토퍼바(160)에 의해 정지됨으로 상기 안전도어(140)와 위드실드의 충돌로 인한 윈드실드(170) 또는 안전도어(140)가 파손을 방지할 수 있게된다.Therefore, the safety door 140 is stopped by the stopper bar 160 before the windshield 170 collides with the windshield 170 or the safety door 140 due to the collision between the safety door 140 and the weed shield. ) Can prevent damage.

이상에서 설명한 바와 같이 인스트러먼트패널의 상단에 에어백이 설치되는 취출홈을 갖는 수납부가 형성되고, 상기 수납부에는 취출홈을 개폐하는 안전도어가 힌지 결합되며, 상기 수납부의 상측 내면에는 안내공을 갖는 지지브라켓이 결합되고, 상기 안전도어의 내측면에는 상기 지지브라켓의 안내공에 삽입되어 슬라이드 함과 아울러 단부에 상기 안내공에 걸리는 걸림돌기가 형성된 스토퍼바가 결합되어 구성된 본 고안인 자동차 에어백 수납부의 안전도어 개폐구조는 펼쳐지는 에어백에 밀려 힌지를 중심으로 회동되는 안전도어를 스토퍼바와 지지브라켓에 의해 윈드실드와 충돌되기 직전까지만 회동되어 개방됨으로 안전도어와 위드실드의 충돌로 방지하여 수리,보수시 불필요한 재원의 낭비를 억제하게됨은 물론 상기 안전도어 및 윈드실드의 파손으로 인해 탑승자의 위험요소를 미연에 방지할 수 있는 효과가 있다.As described above, an accommodating part having an ejection groove in which an air bag is installed is formed at an upper end of the instrument panel, and a safety door for opening and closing the ejection groove is hinged to the accommodating part, and a guide hole is provided on the upper inner surface of the accommodating part. The support bracket having a coupling, and the inner side of the safety door is inserted into the guide hole of the support bracket slides and the stopper bar formed with the engaging projection is formed in the end engaging the guide hole in the car air bag receiving portion The safety door opening and closing structure is rotated by the stopper bar and the support bracket by the stopper bar and the support bracket so that the safety door that is rotated around the hinge is opened and opened to prevent the collision between the safety door and the weed shield. In addition, the waste of unnecessary resources can be suppressed as well as the safety door and the windshield. There is an effect that can prevent the risk of occupants due to damage in advance.
