Description

차량의 좌석벨트 충격흡수장치{Shock absorption equipment of cars seat belt}BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a shock absorber for a vehicle,

본 발명은 차량용 좌석벨트의 충격력을 최소화 시켜 차량의 충돌사고 또는 급제동시 인명과 부상을 최대한 감소시킬 수 있음을 특징으로 한 차량의 좌석벨트충격흡수장치에 관한 것이다.The present invention relates to a seat belt shock absorber for a vehicle, which is capable of minimizing the impact force of a seat belt for a vehicle, thereby minimizing the risk of injury or injury to a vehicle or sudden braking of the vehicle.

최근 차량사고의 급증에 의해 운전자 및 탑승객의 안전에 대한 요구가 증가되면서 그 하나의 방편을 운전자 및 탑승객의 좌석벨트(안전벨트) 착용에 대한 필요성이 대두되고 있는 실정이다. 좌석벨트는 차량의 운행 중 사고발생시 외부의 충격으로 운전자 및 탑승객들이 좌석에서 이탈됨으로서 발생되는 인명피해를 최소화하기 위해 좌석 및 그 주변부의 적정위치에 고정되어 탑승자들을 보호하는 것이다.In recent years, there has been a growing demand for safety of drivers and passengers due to a sudden increase in the number of car accidents. Therefore, there is a need for a driver and a passenger to wear seat belts. The seat belt is secured to an appropriate position of the seat and its periphery to protect the passengers in order to minimize the casualties caused by the driver and the passengers being separated from the seat due to an external impact when an accident occurs during operation of the vehicle.

이에 종래의 수동식 또는 자동식 좌석벨트에 있어서는 벨트착용 후 벨트 권취부에 되감기용 스프링의 힘에 의해 벨트에 되감기려는 힘이 작용하여 승원의 가슴 및 복부부위에 압박감을 주게됨에 따라 이러한 압박감을 주지 않도록 장력을 조절되도록 장치하거나 별도의 클립 등을 벨트에 끼워 벨트 권취부에 걸리도록된 정도이었다.Therefore, in the conventional manual or automatic seat belt, a force to rewind the belt by the force of the rewinding spring is applied to the belt winding part after the belt is worn, so that a pressure feeling is given to the chest and the abdomen part of the wing, Or a separate clip or the like is fitted to the belt so as to be caught by the belt winding portion.

이러한 장치는 차량의 충돌사고나 급제동시 좌석벨트 자체가 고정되기 때문에 외부충격에 의해 탑승자들이 좌석에서 이탈되는 것은 방지할 수 있으나 그 충격력이 탑승자들의 가슴이나 복부부위에 그대로 전달되기 때문에 이로 인한 부상 등은 어쩔 수가 없었다.Such a device can prevent the passengers from being separated from the seat due to an external impact because the seat belt itself is fixed when a vehicle collision accident or sudden braking is performed. However, since the impact force is directly transmitted to the chest or abdomen of the passengers, I could not help it.

좌석벨트의 적당위치에 충격력 흡수장치를 접속연결하여 흡수장치 내에는 단부에 연결바가 끼워진 적당길이의 벨트를 절곡시켜 끼워넣고, 흡수장치의 토출구 측에는 고정편과 조절부의 걸림편 사이에 벨트의 정지돌기 내측부위가 적당한 압력으로 끼워져 있어 차량의 신체에 부상을 줄 정도의 충돌이나 급제동시만 순식간에벨트가 약 10cm가량 저항을 하면서 빠져나감에 따라 좌석벨트를 착용한 탑승자의 가슴과 복부부위에 충격을 흡수 경감시켜 충격에 의한 부상을 극소화함을 목적으로 한 것으로 이를 첨부도면에 의거 상세히 설명하면 다음과 같다.A shock absorbing device is connected to a suitable position of the seat belt and the absorbing device is fitted with a belt having an appropriate length in which a connecting bar is fitted in the end portion of the absorbing device, Since the inner part is fitted with a proper pressure, the belt is about 10 cm in resistance instantly when it collides enough to injure the body of the vehicle or suddenly, and impacts on the chest and abdomen of the occupant wearing the seat belt The present invention aims at minimizing the injury caused by impact by reducing the amount of water absorbed, and will be described in detail with reference to the accompanying drawings.

첨부도면에 있어서,In the accompanying drawings,

도1은 본 발명의 설치위치를 표현한 좌석벨트의 사시도로서 좌석벨트(7)의 적당위치에 설치하는 것으로 착용자의 가슴이나 복부부위를 피하는 것이 당연하며 주로 벨트고정부(15a), 또는 권치부 가까이 장치하되 권취부(15)의 작동에 방해를 주어서는 않된다.FIG. 1 is a perspective view of a seat belt representing an installation position of the present invention. It is provided at an appropriate position of the seat belt 7 to avoid the chest or the abdominal region of the wearer and is mainly a belt fixing portion 15a, But it should not interfere with the operation of the winding unit 15. [

도2는 본 발명의 작동상태를 나타낸 단면도이고,2 is a cross-sectional view showing an operating state of the present invention,

도3은 본 발명의 흡수장치 내에 설치된 조절부의 확대 단면도로서, 벨트(7)의 적당부위를 절단하되, 한 벨트(7)부위에는 흡수장치(4)의 케이스(1)에 설치된 고정바(8)에 통상과 같이 연결하고, 타 벨트(7)부위는 흡수장치(4)의 케이스(1)에 구성된 토출구(2)를 통과하여 연결바(9)에 연결하여 벨트(7) 일측에 설치된 정지돌기(12)가 흡수장치(4)의 케이스(1)에 구성된 토출구(2)에 닿을때까지 당긴다음 조절부(14)의 드라이버홈(11)에 드라이버를 끼우고 잠구어주면 고정편(6)과 걸림편(5)에 의하여 벨트(7)를 잡아주게 된다. 이때 고정편(6)과 걸림편(5)의 벨트(7)가 닿는 부위에 다수의 걸림돌기(13)가 돌설되어 있어 벨트(7)를 정확히 잡아주도록 되어있다. 조절부(14)는 흡수장치(4)의 케이스(1) 내측에 고정된 고정너트(2)와 조절부(14)의 나선돌기(10)에 의하여 조여지거나 풀어주도록 되어있다. 이와 같이 구성된 본 발명은 운전자 또는 탑승객 등의 탑승자가 통상의 좌석벨트(7)와 같이 하면 된다.Fig. 3 is an enlarged cross-sectional view of a regulating portion provided in the absorbing device of the present invention, in which a suitable portion of the belt 7 is cut, And the other belt 7 is connected to the connecting bar 9 through the discharge port 2 formed in the case 1 of the absorbing device 4 and is connected to the belt 7 via a stop The protrusion 12 is pulled until the protrusion 12 touches the discharge port 2 formed in the case 1 of the absorber 4 and then the driver is inserted into the driver groove 11 of the regulating portion 14 and locked, And the engaging piece 5 to hold the belt 7 thereon. At this time, a plurality of locking protrusions 13 protrude at a position where the fixing piece 6 and the engaging piece 5 come into contact with the belt 7, so that the belt 7 can be accurately caught. The adjustment portion 14 is adapted to be tightened or loosened by the fixing nut 2 fixed to the inside of the case 1 of the absorption device 4 and the spiral projections 10 of the adjustment portion 14. In the present invention constructed as described above, the occupant of the driver or the passenger may have the same seat belt 7 as the normal seat belt.

상기한 본 발명을 착용한 상태에서 다른 차량에 충돌하거나 추돌당하는 경우 및 급정지하여 탑승자가 정도 이상으로 신체에 충격이 오게되면 조절부(14)의 걸림편(5)과 고정편(6) 사이에 끼워진 벨트(7)가 흡수장치(4)의 케이스(1)에 구성진 토출구(2)가 빠져나가면서 벨트(7)의 내단에 연결된 연결바(9)가 걸림편(5)과 고정편(6) 간에 걸려 더 이상의 토출은 되지 않으나 벨트(7)의 연결바(9)와 정지돌기(12) 사이의 길이가 약 10cm정도 되므로 결국 벨트(7)가 10cm정도 길어지면서 탑승자의 신체적 충격을 흡수하여 밸브(7) 충격에 의한 신체를 보호할 수 있도록 된 것이다.When the vehicle collides with or collides with another vehicle in the state where the present invention is worn, or when the occupant suddenly impacts the vehicle more than the predetermined degree, the locking part (5) of the control part (14) The inserted belt 7 is inserted into the case 1 of the absorbing device 4 so that the connection bar 9 connected to the inner end of the belt 7 as the ejection port 2 is disengaged is engaged with the engaging piece 5 and the fixing piece 6 The length between the connecting bar 9 of the belt 7 and the stopper protrusion 12 is about 10 cm. As a result, the belt 7 is lengthened by about 10 cm to absorb the physical impact of the occupant The valve (7) is designed to protect the body from impact.

이때 조절부(14)의 드라이버홈(11)에 드라이버를 끼워 조절부(14)의 걸림편(5)과 고정편(6) 간에 끼워진 벨트(7)의 조임을 적당히 하여 평상시에는 공지의 벨트(7)와 같이 벨트(7)가 풀려 나오지 않도록 하며 큰 충격을 받을 때만 벨트(7)가 흡수장치(4)의 케이스(1)에 구성된 토출구(2)로 풀려 나오도록 조절하며 조절부(14)와 고정너트(3)의 나선돌기(10)에 의해 조정 가능토록 되어있다.At this time, a screwdriver is fitted to the driver groove 11 of the adjusting portion 14 to appropriately tighten the belt 7 sandwiched between the engaging piece 5 of the adjusting portion 14 and the fixing piece 6, 7 so that the belt 7 is released to the discharge port 2 formed in the case 1 of the absorbing device 4 and only when the belt 7 is subjected to a large impact, (10) of the fixing nut (3).

일단 상기한 바와 같이 흡수장치(4)의 케이스(1)로부터 풀려진 벨트(7)는 도2의 "A"와 같이 원상복구시켜 재차 사용에 대비하는 것이 당연하나 이러한 경우가 드물고 인명이 중요하기 때문에 이에 대한 구체적인 원상복구 시키는 것에 큰 중점을 두지 않았으나 도2의 B상태에서 A상태로 하는 것이 간단하다.As described above, it is natural that the belt 7 released from the case 1 of the absorbing device 4 is restored to the original state as in "A" of FIG. 2 and prepared for use again. However, Therefore, although it is not particularly focused on restoring the original state, it is simple to set the state A to the state B in FIG. 2.
