Abstract

PURPOSE: An airbag interlocking with a seat transferring apparatus is provided to deploy an airbag near a passenger with a small inflator and the compact airbag. CONSTITUTION: An airbag module(A) is installed with facing a fixed seat(S). A seat transfer apparatus(20) is adjusted by a seat transfer switch(SW) to place the seat properly to a body of a passenger. The seat transfer apparatus moves forward or backward by operating the switch. The airbag module is moved forward or backward as the same distance in the same direction by a driving unit to be close to the passenger. A rotating rod is turned by rotating a motor(51) according to the switch operation. An external threaded part of the rotating rod rotates with engaging with an internal threaded part of a fixing bracket. The airbag module slides with the fixing bracket along a guide rail(60), and moves forward and backward as the transfer distance of the seat in the same direction.

Description

시트 이송과 연동되는 도어용 에어백 장치Airbag device for doors that interlocks with sheet transport

본 발명은 차량의 도어용 에어백 장치에 관한 것으로서, 더 상세하게는, 시트의 전후 이동에 따라 도어에 장착된 에어백 장치가 동일방향으로 동일 거리만큼 이동되도록 구성함으로써, 에어백이 항상 탑승자와 인접한 최적의 위치에서 전개될 수 있도록 한 시트 이송과 연동되는 도어용 에어백 장치(Door-mounted Air bag Sliding Device Transferred with Seat Sliding Apparatus for Air Bag Module Mounted on Door of Car)에 관한 것이다.The present invention relates to an airbag device for a door of a vehicle, and more particularly, by configuring the airbag device mounted on the door to be moved by the same distance in the same direction as the seat moves forward and backward, so that the airbag is always adjacent to the occupant. Door-mounted Air bag Sliding Device Transferred with Seat Sliding Apparatus for Air Bag Module Mounted on Door of Car.

에어백 장치는, 탑승자를 위한 안전 장치로서, 차량의 충돌시 탑승자와 차량 구조물 사이에 에어백이 펼쳐지도록 함으로써, 탑승자가 차량 구조물에 직접적으로 부딪쳐 부상을 입게 되는 것을 방지하는 장치이다. 이러한 에어백 장치는, 필요에 따라 차량의 각 부위에 설치되는데, 전방 충돌시 탑승자의 상체 및 머리부위를 보호하기 위한 스티어링 휠 내부 및 글로브 박스 상측에 장착되는 에어백 장치와, 측면 충돌시 탑승자와 도어 사이에 펼쳐져 탑승자를 보호하기 위하여 도어 내측에 장착된 에어백 장치를 그 대표적인 예로 들 수 있다.The airbag device is a safety device for the occupant. The airbag device is a device that prevents the occupant from directly injuring the vehicle structure by causing the airbag to be deployed between the occupant and the vehicle structure during a collision of the vehicle. Such an airbag device is installed in each part of the vehicle as needed. The airbag device is mounted inside the steering wheel and the upper side of the glove box to protect the upper body and the head of the occupant in front of the collision, and between the occupant and the door in the side collision. A representative example is an airbag device mounted inside the door to protect the occupant.

그러나, 차량의 시트가 전후로 이동됨에 따라 탑승자의 위치 또한 전후로 이동되는데 반하여, 종래 도어에 장착된 에어백 장치(11)는, 도 1에 도시된 바와 같이, 도어(10)의 내측에 고정 장착되는 구조를 갖는다. 이에 따라, 시트의 이동에 따른 탑승자의 모든 위치에 대하여 전개된 에어백(11)이 그 효력을 발휘할 수 있도록 종래 도어(10)에 장착되는 에어백(11)은 큰 크기로 제작되어야 할뿐만 아니라, 이와 같이 큰 에어백(11)을 전개시키기 위하여 대용량의 인플레이터가 구비되어야 하는 불편함이 있었다.However, as the seat of the vehicle is moved back and forth, the position of the occupant is also moved back and forth, whereas the airbag device 11 mounted to the conventional door is fixedly mounted to the inside of the door 10, as shown in FIG. Has Accordingly, the airbag 11 mounted to the conventional door 10 is not only to be manufactured in a large size so that the airbag 11 deployed in all positions of the occupant according to the movement of the seat can take effect. In order to deploy the large airbag 11 as described above, there was an inconvenience that a large capacity inflator should be provided.

따라서, 본 발명은 상기와 같은 문제점을 해결하기 위하여 안출된 것으로, 시트의 전후 이동에 따라 도어에 장착된 에어백 장치가 동일방향으로 동일 거리만큼 이동되도록 구성하여, 차량의 충돌시 에어백이 항상 탑승자와 인접한 최적의 위치에서 전개될 수 있도록 구성함으로써, 소용량의 에어백과 인플레이터로도 에어백의 전개시 최상의 에어백 전개 효과를 얻을 수 있도록 한 시트 이송과 연동되는 도어용 에어백 장치를 제공하는데 주된 목적이 있다.Therefore, the present invention is devised to solve the above problems, the airbag device mounted on the door according to the forward and backward movement of the seat is configured to be moved by the same distance in the same direction, the airbag is always with the occupant The main purpose is to provide an airbag device for a door that is interlocked with a seat conveying, so that the airbag and the inflator with a small capacity can achieve the best airbag deployment effect when the airbag is deployed.

And to advance or reverse the airbag module A by a distance equal to S). This drive unit is configured to include a motor 51, a rotating rod 52 and a fixing bracket 53. The fixing bracket 53 is a member fixedly attached to the rear surface of the airbag module A, and is configured such that a female screw portion 53a communicating in the direction of the guide rail 60 is formed at the center thereof. In addition, the rotating rod 52 is disposed in the longitudinal direction of the guide rail 60, the outer peripheral surface of the male screw portion 52a engaging with the female screw portion 53a is formed continuously, the motor 51 is According to the input signal to form a structure coupled to the one end of the rotating rod 52 to the forward and reverse rotation of the rotating rod (52).

또한, 이와 같이 장착되는 에어백 모듈(A)의 차 내부 측에는 에어백 전개용 도어(70)가 형성되는데, 이 도어(70)의 내측에는, 에어백의 전개시 도어(70)가 절개될 수 있도록, 에어백 모듈(A)이 슬라이딩되는 구간을 따라 노치부(71)가 형성된다.In addition, an airbag deployment door 70 is formed on the inside of the vehicle of the airbag module A, which is mounted as described above. Inside the door 70, the airbag may be cut when the airbag is deployed. A notch 71 is formed along a section in which the module A slides.

상기와 같은 구성에 의하여, 상기 에어백 모듈(A)의 장착시, 고정된 시트(S)와 대응되는 위치에 에어백 모듈(A)이 위치하도록 설치한다. 이와 같은 상태에서, 탑승자가 자신의 체형 및 취향에 맞도록 시트(S)의 위치를 조절할 경우, 시트 이송용 스위치(SW)를 조작하여 시트 이송장치(20)를 조절하게 되는데, 이 스위치(SW)의 작동에 따라 시트 이송장치(20)가 전진 또는 후진됨과 동시에, 상기 구동부가 작동되어 에어백 모듈(A)을 동일방향으로 동일간격만큼 전진 또는 후진시키게 됨으로써, 에어백 모듈(A)은 항상 탑승자와 인접한 최적의 위치에 있게 되는 것이다. 즉, 상기 스위치(SW)의 작동에 따라 상기 모터(51)가 정역회전됨으로써, 회전봉(52)이 정역회전되게 되는데, 이때, 이 회전봉(52)의 수나사부(52a)가 고정 브래킷(53)의 암나사부(53a)와 맞물려 회전됨으로써, 상기 고정 브래킷(53)과 함께 에어백 모듈(A)이 안내 레일(60)을 따라 슬라이딩되며 상기 시트(S)의 이송거리만큼 동일한 방향으로 전진 및 후진하게 되는 것이다.By the above configuration, when the airbag module A is mounted, the airbag module A is installed at a position corresponding to the fixed seat S. FIG. In this state, when the occupant adjusts the position of the seat (S) to suit his or her body shape and taste, the seat transporting device (SW) is operated to adjust the seat conveying device 20, this switch (SW) As the sheet conveying apparatus 20 moves forward or backward in accordance with the operation of), the driving unit is operated to move the airbag module A forward or backward by the same interval in the same direction, so that the airbag module A always remains with the occupant. It will be in the best position adjacent to it. That is, as the motor 51 is reversely rotated according to the operation of the switch SW, the rotating rod 52 is reversely rotated. In this case, the male screw portion 52a of the rotating rod 52 is the fixing bracket 53. By rotating in engagement with the female thread portion (53a) of the, the airbag module (A) together with the fixing bracket 53 is slid along the guide rail 60 and forward and backward in the same direction by the conveying distance of the seat (S) Will be.

상기 일 실시예에 의하여 알 수 있는 바와 같이, 본 발명을 따른 시트 이송과 연동되는 도어용 에어백 장치에 의하여, 도어에 장착된 에어백이 시트의 위치와 관계없이 항상 탑승자와 인접한 최적의 위치에 있게 됨으로써, 도어용 에어백 및 그 인플레이터를 소용량으로 제작하여도 최상의 에어백 전개 효과를 얻을 수 있는 효과가 있다. 또한 소용량의 에어백의 장착시, 에어백의 전개 소요시간이 단축됨으로써, 차량의 충돌시 빠른 에어백 전개에 의하여 에어백의 신뢰성을 향상시킬 수 있는 효과가 있다.As can be seen by the above embodiment, by the airbag device for the door interlocked with the sheet conveying according to the present invention, the airbag mounted on the door is always in the optimum position adjacent to the occupant regardless of the position of the seat Even if the door airbag and its inflator are manufactured in a small capacity, the best airbag deployment effect can be obtained. In addition, when the small-capacity airbag is installed, the deployment time of the airbag is shortened, thereby improving the reliability of the airbag by rapidly deploying the airbag during a collision of the vehicle.

이상에서 본 발명의 일 실시예에 따른 시트 이송과 연동되는 도어용 에어백 장치에 대하여 설명하였으나, 본 발명은 이에 한정하지 아니하며, 당업자라면 여러 가지로 그 변형과 응용이 가능할 것이다.Although the airbag device for the door interlocked with the sheet conveying apparatus according to an embodiment of the present invention has been described above, the present invention is not limited thereto, and various modifications and applications will be possible to those skilled in the art.
