Description

차량의 좌석벨트 충격흡수장치{Shock absorption equipment of cars seat belt}Shock absorption equipment of cars seat belt

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 of a vehicle, characterized in that it is possible to minimize the impact force of the seat belt for the vehicle to minimize the loss of life and injury during a crash 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.Recently, as the demand for driver and passenger safety has increased due to the rapid increase in vehicle accidents, the necessity of wearing a seat belt (safety belt) for drivers and passengers is emerging. The seat belt is fixed at the proper position of the seat and its periphery to protect the occupants in order to minimize the human injury caused by the driver and passengers being disengaged from the seat due to an external shock during an accident during driving 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.Accordingly, in the conventional manual or automatic seat belts, the force to rewind the belt by the force of the spring for rewinding the belt winding part after the belt is applied acts to give pressure to the thorax and the abdomen of the crew so as not to give such a feeling of tension. The device was adjusted so as to fit the belt or a separate clip was caught to 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 prevents occupants from escaping from the seat due to external impacts because the seat belt itself is fixed during a crash or sudden braking of the vehicle, but the impact force is transmitted to the chest or abdomen of the occupant as it is. 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.Connect the impact force absorber to the proper position of the seat belt and bend the belt of the appropriate length with the connecting bar inserted at the end in the absorber.The belt stop projection between the fixing piece and the engaging piece of the adjusting part on the discharge port side of the absorber. The inner part is fitted with the proper pressure, so the belt will resist about 10cm in an instant when only a collision or a sudden braking will injure the body of the vehicle. It is intended to minimize the injury caused by impact by reducing the absorption, which will be described in detail according 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.1 is a perspective view of a seat belt expressing the installation position of the present invention is to be installed at the proper position of the seat belt (7), it is natural to avoid the wearer's chest or abdomen, mainly the belt fixing portion (15a), or close to the toothed portion The device 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.3 is an enlarged cross-sectional view of a control unit installed in the absorber of the present invention, wherein a suitable portion of the belt 7 is cut off, and one belt 7 is fixed to the case 1 of the absorber 4 at a portion of the belt 7. ) And the other belt (7) part is connected to the connecting bar (9) by passing through the discharge port (2) formed in the case (1) of the absorber (4) and installed on one side of the belt (7). Pull the projection 12 until it reaches the discharge port 2 formed in the case 1 of the absorber 4, and then insert the screw into the driver groove 11 of the adjusting unit 14 and lock the fixing piece 6 ) And the belt 7 by the locking piece 5. At this time, a plurality of locking projections 13 protrude from the contact area of the belt 7 of the fixing piece 6 and the locking piece 5 so as to accurately grasp the belt 7. The adjusting unit 14 is tightened or released by the fixing nut 2 fixed inside the case 1 of the absorber 4 and the spiral protrusion 10 of the adjusting unit 14. According to the present invention configured as described above, a passenger such as a driver or a passenger may have the same form as a normal seat belt 7.

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.In the state of wearing the present invention when the collision or collision with other vehicles and when the occupant is shocked to the body by more than enough to occupy the body between the engaging piece 5 and the fixing piece 6 of the adjusting unit 14 As the fitted belt 7 exits the discharge port 2 formed in the case 1 of the absorber 4, the connecting bar 9 connected to the inner end of the belt 7 is caught by the locking piece 5 and the fixing piece 6. ), But no further discharge is possible, but the length between the connecting bar 9 and the stop projection 12 of the belt 7 is about 10 cm, so that the belt 7 is about 10 cm long and absorbs the physical impact of the occupant. The valve 7 is to protect the body by the 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, the driver is inserted into the driver groove 11 of the adjusting unit 14 to properly tighten the belt 7 sandwiched between the locking piece 5 and the fixing piece 6 of the adjusting unit 14, and a known belt ( As shown in 7), the belt 7 is not released, and the belt 7 is adjusted to be released to the discharge port 2 configured in the case 1 of the absorber 4 only when subjected to a large impact, and the adjusting part 14 And the helix projection 10 of the fixing nut 3 can be adjusted.

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, the belt 7 released from the case 1 of the absorber 4 should be restored to its original state as shown in "A" of FIG. For this reason, the specific restorative restoration is not given a great emphasis, but it is simple to change from the state B to the state A in FIG.

상술한 바와 같이 본 발명은 흡수장치(4)의 케이스(1)를 좌석벨트(7)의 적당부위에 장치하여 타 차량에 충돌하거나 추돌 당한 경우 및 급제동시 탑승자의 좌석벨트(7)에 전달된 충격이 보통 이상의 경우에 본 발명의 흡수장치(4)의 케이스(1)에 내장된 벨트(7)가 서서히 약 10cm정도가 큰 저항을 하면서 빠져 나오도록 하므로 느낌은 순간적이지만 벨트(7)의 조절부(14)에 의하여 상기 전달된 벨트(7)의 충격을 흡수하여 충격력을 경감시켜 부상의 정도를 크게 줄일 수 있도록 하므로 탑승자는 신체의 부담 없이 교통사고의 위험으로부터 신체를 보호할 수 있도록 된 것이다.As described above, according to the present invention, the case 1 of the absorber 4 is installed at an appropriate portion of the seat belt 7 so as to be transmitted to the seat belt 7 of the occupant in case of collision or collision with another vehicle and during sudden braking. When the impact is more than normal, the belt 7 embedded in the case 1 of the absorber 4 of the present invention gradually exits with a large resistance of about 10 cm. By absorbing the impact of the belt (7) transmitted by the part 14 to reduce the impact force to greatly reduce the degree of injuries so that occupants can protect the body from the risk of traffic accidents without burdening the body .
