[산업상 이용분야][Industrial use]
본 고안은 에어백 장착차량에 있어서, 차량 충돌시 탑승자 가슴 충격치를 줄이기 위해 사용되는 시트벨트 리트랙터(Retractor)구조에 관한 것이다.The present invention relates to a seat belt retractor structure that is used to reduce the occupant's chest impact value in a vehicle crash in an airbag mounted vehicle.
[종래 기술][Prior art]
잘 알려진 바와 같이, 운전조작에 불편함이 없고, 긴급시에는 확실하게 승객을 보호한다는 시트벨트 리트랙터는 시트벨트를 풀었을때 자동적으로 시트밸트를 신속히 감아 승객을 보호하는 구조로 되어 있다.As is well known, the seat belt retractor, which has no inconvenience in driving operation and reliably protects the passenger in an emergency, is structured to automatically protect the passenger by quickly winding the seat belt when the seat belt is released.
즉, 스풀에 권취된 시트벨트를 차량 충돌시 신속히 풀어져 승객의 가슴을 조이도록 함으로써, 객실내의 임의부위에 승객의 상,하체가 충돌되지 않도록 의자에 붙잡아 두는 기능을 가지게 되는데, 이때 웨빙(WEBBING: 벨트)이 무한정 조여져 승객의 가슴을 조이게 되므로 가슴압박에 의한 상해를 입는 문제점이 지적되고 있다.In other words, by fastening the seat belt wound on the spool to fasten the passenger's chest in the event of a vehicle crash, it has a function of holding the seat to the chair so that the upper and lower body of the passenger does not collide with any part of the cabin, webbing (WEBBING: Since the belt is tightened indefinitely to tighten the passenger's chest, the problem of injury caused by chest compression is pointed out.
[고안이 해결하고자 하는 과제][Problem to Solve]
본 고안은 상기와 같은 종래 기술의 문제점을 해소하기 위하여 안출한 것으로, 차량이 충돌되면 어느 한도까지만 웨빙이 인출되고, 그 이후에는 웨빙의 인출을 정지시켜 승객의 가슴에 압박을 가하지 않도록 함으로써 웨빙 압박에 의한 가슴상해를 방지하도록 하기 위한 것이다.The present invention has been made in order to solve the problems of the prior art as described above, webbing is drawn out to a certain limit when the vehicle collides, after that webbing pressure by stopping the withdrawal of the webbing so as not to press the passenger's chest It is to prevent the chest injury caused by.
[과제를 해결하기 위한 수단][Means for solving the problem]
상기한 과제를 달성하기 위한 본 고안을 리트랙터 브라켓 내부에 설치한 스풀에 웨빙이 권취되어 있는 것에 있어서, 상기 스풀내에 내설시킨 로킹휠과 일체로 형성시킨 토션바와, 상기 로킹휠을 로크 또는 언로크 시키는 로커와, 상기 로커를 작동시키는 볼센서부로 구성됨을 특징으로 한다.A webbing is wound on a spool provided in the retractor bracket to achieve the above object, and a torsion bar formed integrally with a locking wheel built into the spool, and the locking wheel is locked or unlocked. To rocker, and characterized in that consisting of a ball sensor unit for operating the rocker.
[실시예]EXAMPLE
리트랙터 브라켓(1)내에 설치한 스풀(2)에 웨빙(3)이 권취되어 있고, 일측의 리트랙터 브라켓(1)외측에 설치한 로킹휠(4)에 일체로 형성시킨 토션부(5)를 상기 스풀(2)내에 설치하되, 토션바(5)일측을 연설시켜 리와인드 휠(8)에 끼우고, 토션바(5)일단은 제2도에 도시한 바와 같이 요입부(5A)를 형성하여 스풀(2)의 절곡부(2A)서 서로 맞물리게 결합하도록 한다.Torsion part 5 formed by webbing 3 on the spool 2 installed in retractor bracket 1 and integrally formed on rocking wheel 4 provided on one side of retractor bracket 1. Is installed in the spool (2), and one side of the torsion bar (5) is extended and inserted into the rewind wheel (8), and one end of the torsion bar (5) forms a recessed portion (5A) as shown in FIG. To be engaged with each other at the bent portion 2A of the spool 2.
그리고, 상기 로킹 휠(4)하방에는 볼센서부(6)의 볼(6A)에 의해 작동되는 로커(7)를 설치하여 차량 충돌시 로킹휠(4)을 로킹하도록 구성한다.Then, below the locking wheel 4, a rocker 7 operated by the ball 6A of the ball sensor unit 6 is installed to lock the locking wheel 4 in a vehicle crash.
이와 같은 구성을 가진 본 고안은 차량이 충돌 또는 그에 준하는 충격이 차량에 전달되게 되면, 볼센서부(6)의 충격감지에 의해 볼(6)이 로커(7)를 작동 즉, 로커(7)가 로킹휠(4)에 강하게 면접되어 로킹휠(4)의 회전을 정지시키게 된다.According to the present invention having such a configuration, when a vehicle collides or a shock corresponding thereto is transmitted to the vehicle, the ball 6 operates the rocker 7 by the impact detection of the ball sensor unit 6, that is, the rocker 7. Is strongly interviewed with the locking wheel 4 to stop the rotation of the locking wheel 4.
이에 따라 토션바(5)측과 토션바(5)의 요입부(5A)와 결합된 스풀(2)의 절곡부(2A)에 힘이 전달되어 스풀(2)에 감겨있는 웨빙(3)의 인출이 정지하게 된다.Accordingly, the force is transmitted to the bent portion 2A of the spool 2 coupled with the torsion bar 5 side and the recessed portion 5A of the torsion bar 5, so that the webbing 3 wound around the spool 2 Withdrawal stops.
다시말하면, 차량 충돌시 신속히 웨빙(3)이 인출되어 승객을 붙잡아 두게 되는데, 이때, 로킹휠(4)의 정지에 따라 스풀(2)도 정지되면서 웹이(3)의 인출이 정지되게 된다.In other words, when the vehicle crashes, the webbing 3 is quickly taken out to hold the passenger. At this time, withdrawal of the web 3 is stopped while the spool 2 is also stopped according to the stop of the locking wheel 4.
그러나, 이 상태에서 보다 더 큰 힘 즉, 토션바(5)의 토션힘 이상의 힘이 웨빙(3)에 가해지면 토션바(5)는 스풀(2)일측에 고정된 상태이므로 비틀림이 일어나게 되고, 이로 인해 어느 한도까지 웨빙(3)이 더 인출되나, 토션바(5)의 비틀림 모멘트가 커져서 웨빙(3)의 인출은 중지되게 된다.However, in this state, when a larger force, that is, a force greater than the torsion force of the torsion bar 5 is applied to the webbing 3, the torsion bar 5 is fixed to one side of the spool 2, so that torsion occurs. Due to this, the webbing 3 is further drawn out to a certain extent, but the torsion bar 5 of the torsion bar 5 becomes large, and the withdrawal of the webbing 3 is stopped.
이와 같이 차량 충돌시 웨빙(3)의 인출이 정지됨에 따라 승객의 가슴을 웨빙이 어느정도는 압박하나, 상해를 입힐만큼 압박하지 않게 됨으로써 본 고안은 승객을 안전하게 보호하게 되고 이와 같은 효과에 의해 차량의 신뢰성도 높아지는 실용적인 고안이다.As the withdrawal of the webbing 3 is stopped during the vehicle collision, the webbing of the passenger's chest is pressed to some extent, but not enough to cause injury, so the present invention protects the passengers safely. It is a practical design that also increases reliability.
