FIG. 4 is a cross-sectional view illustrating a post-operational state of the present invention. In this embodiment, the fixing bolt 36 is fitted to an upper portion of the rail 30 fixed to the side pillar 38 of the vehicle body by the fixing bolt 36. A plurality of fixing holes 32a, 32b, and 32c are integrally formed with the fixing member 31 formed in the up and down directions, and between the fixing holes 32a, 32b and 32c of the fixing member 31, the seat belt ( The ribs 34a, 34b, and 34c which are broken when a predetermined tensile force is applied to 10 are formed.

상기 레일(30)에는 안전벨트(10)가 끼워진 벨트고리(12)가 결합된 벨트걸이(14)가 높이조절가능하게 설치되는 것이다.The rail 30 is a belt hanger 14 coupled to the belt ring 12 is fitted with a seat belt 10 is installed to be adjustable height.

또, 상기 레일(30)의 고정부재(31)에 형성되는 고정공(32a,32b,32c)은, 하부에서 상부로 갈수록 점차적으로 좁아지게 형성됨으로써 각 고정공(32a,32b,32c) 사이에 형성되는 리브(34a,34b,34c)의 길이도 상방으로 갈수록 점차적으로 좁아지게 형성되는 것이다.In addition, the fixing holes 32a, 32b, and 32c formed in the fixing member 31 of the rail 30 are gradually narrowed from the lower part to the upper part, and thus, between the fixing holes 32a, 32b, and 32c. The length of the ribs 34a, 34b, and 34c to be formed is also gradually narrowed upward.

이와 같이 구성된 본 발명은 레일(30)을 필라(38)에 장착할 때, 고정볼트(36)를 맨 하단 고정부재(31)의 고정공(32a)에 끼워 고정하면 되는 것이고, 차량의 운행시 안전벨트(10)를 착용하게 될 때에는 벨트걸이(14)를 필라(38)에 부착된 레일(30)의 소정높이에 걸어 안전벨트(10)의 높이조절을 하여 탑승객의 신체에 맞게 사용할 수 있는 것이며, 정상적인 차량운행시에 발생하는 급정거 등의 경우에는 레일(30)의 고정상태가 변하지 않고 일정하게 유지하게 되나, 차량충돌 및 그와 유사한 급감속시의 경우에는 안전벨트(10)에 걸리는 인장력이 커지게 됨으로써 레일(30)에 가해지는 인장력도 높아지게 되어 레일(30)이 하방으로 잡아당겨지게 되는 것이며, 이때 하부의 고정공(32a)에 끼워진 고정볼트(36)는 제4도에 도시한 바와 같이, 상대적으로 이 고정공(32a) 상부의 리브(34a)를 파손시키면서 바로 위의 고정고에(32b)으로 위치 이동을 하게 되는 것이며, 이러한 과정이 순차적으로 반복되면서 안전벨트(10)가 다단계로 신장되는 것이다.When the rail 30 is mounted on the pillar 38, the present invention configured as described above may fix the fixing bolt 36 to the fixing hole 32a of the lowermost fixing member 31 to fix the rail 30. When the seat belt 10 is to be worn, the belt hanger 14 is hooked to a predetermined height of the rail 30 attached to the pillar 38 to adjust the height of the seat belt 10 so that the seat belt 10 can be used to fit the passenger's body. In the case of a sudden stop occurring during normal vehicle driving, the fixed state of the rail 30 remains unchanged, but in the case of a vehicle crash or similar sudden deceleration, the tension applied to the seat belt 10 As the tension is applied to the rail 30, the tension 30 is increased so that the rail 30 is pulled downward, and the fixing bolt 36 fitted into the lower fixing hole 32a is shown in FIG. As shown, the upper part of this fixing hole 32a is relatively Would be to go to the position (32b) in fixed and just above the breakage while the (34a), this process will be repeated as the sequentially seat belt (10) height in multiple stages.

한편, 상기 리브(34a,34b,34c)는 상방으로 갈수록 길이가 짧아지도록 형성하였으므로, 충돌사고시 초기에는 쉽게 파손되나, 그후로는 점차적으로 많은 힘이 가해져야 파손되어지므로 안전벨트(10)에 가해지는 인장력을 효과적으로 흡수하게 되는 것이다.On the other hand, since the ribs 34a, 34b, and 34c are formed to have a shorter length toward the upper side, the ribs 34a, 34b, and 34c are easily broken at the time of a crash accident, but are subsequently applied to the seat belt 10 because they are gradually broken down. It will effectively absorb the tensile force.

이처럼 본 발명은 충돌사고시 레일(30) 상부에 형성된 고정부재(31)의 고정공(32a,32b,32c) 사이에 형성된 리브(34a,34b,34c)가 고정볼트(36)에 의하여 파손되면서 레일(30)이 필라(38)의 하방으로 다단식으로 슬라이드되면서 안전벨트(10)를 신장시킴으로써 안전벨트(10)와 신체와의 접촉시간을 지연시키게 되면서 신체에 가해지는 압박력을 분할시켜 주게 되어 신체에 가해지는 충격을 감소시켜 주게 되는 것이다.As such, the present invention is a rib (34a, 34b, 34c) formed between the fixing holes (32a, 32b, 32c) of the fixing member 31 formed on the rail 30 in the event of a crash while the rail is damaged by the fixing bolt 36 As the 30 slides down the pillar 38 in a multi-stage manner, the seat belt 10 is stretched to delay the contact time between the seat belt 10 and the body while dividing the pressing force applied to the body. It will reduce the impact on.

이상 설명한 바와 같이 본 발명은, 벨트걸이가 고정되는 레일의 상부에 일체로 형성된 고정부재에 다단의 고정공을 형성시키고, 각 고정공 사이에는 안전벨트의 인장력에 의하여 파괴되는 리브를 형성시켜, 차량의 충돌사고시 필라에 부착된 레일이 하방으로 슬라이드되면서 다단계로 걸리도록 한 것으로, 본 발명에 의하면 충돌사고 등의 경우, 안전벨트가 급격히 신장이 정지되면서 신체를 압박하게 될 때, 안전벨트의 일단이 연결된 레일이 필라의 하방으로 슬라이드되면서 안전벨트의 길이를 다단으로 신장시켜줌으로써 안전벨트에 의하여 신체에 가해지는 압박을 최소화하고, 순간적인 충격을 완화시켜 줌으로써 운전자 및 탑승자들이 안전벨트에 의하여 치명적인 부상을 당하게 되는 것을 방지할 수 있는 유용한 효과를 갖는다.As described above, the present invention forms a multi-stage fixing hole in the fixing member integrally formed on the upper portion of the rail on which the belt hanger is fixed, and between each fixing hole is formed a rib that is destroyed by the tension of the seat belt, the vehicle When the crash of the rail attached to the pillar slides downwards to take a multi-step, according to the present invention, in the case of a crash, such as when the seat belt is suddenly stopped elongating to press the body, one end of the seat belt As the connected rail slides down the pillar, the seat belt is extended in multiple stages to minimize the pressure applied to the body by the seat belt and to mitigate momentary shocks, thereby preventing the driver and passengers from being injured by the seat belt. It has a useful effect that can be prevented from getting hit.
