본 발명은 충돌사고시 안전벨트에 의하여 신체에 가해지는 압박을 최소화 할 수 있도록 한 자동차 안전벨트의 충격흡수장치에 관한 것이다.The present invention relates to a shock absorbing device of a vehicle seat belt to minimize the pressure applied to the body by the seat belt in a crash accident.
종래 자동차의 시트에 장착되어 있는 안전벨트는 충돌사고 등의 경우, 운전자 및 탑승객이 차내 전방의 핸들, 대시패널 및 윈드실드 등의 고형물에 부딪히게 되거나 윈드실드밖으로 튀어나가게 되므로써 받게 되는 2차적인 충돌에 의하여 사망 또는 상해를 입게 되는 것을 방지하는 기능을 갖고 있었으며, 이러한 안전벨트는 정상적인 상태에서의 급정차시나 운전자 및 승객이 차내에서 몸을 가눌때에는 자유자재로 신축가능하고, 비정상적인 급격한 감속 및 충돌사고 등에 의한 급감속시에는 안전벨트의 신장이 정지되어 운전자 등의 신체가 전방으로 밀려나가게 되는 것을 방지할 수 있는 장치가 구비되어 있다.In the case of a crash, a seat belt that is conventionally mounted on a seat of a vehicle is a secondary collision that is caused by a driver or a passenger hitting a solid object such as a steering wheel, a dash panel, and a windshield in front of the vehicle or jumping out of the windshield. It has a function to prevent death or injury due to the accident, and this seat belt can be freely stretched in a sudden stop under normal conditions or when the driver and passengers rest on the vehicle. In the case of sudden deceleration by the back, the device is provided with a device which can prevent the extension of the seat belt to stop the body such as the driver from being pushed forward.
한편, 상기한 종래의 안전벨트에 있어서는 충돌사고시 안전벨트는 신장이 정지되므로 관성력에 의하여 운전자 등의 신체가 전방으로 밀리게 될 때, 신장이 정지된 안전벨트가 운전자 등의 신체 특히, 흉부를 강한 힘으로 압박하게 되므로써 안전을 위한 안전벨트가 역으로 작용하여 안전벨트에 의하여 신체가 치명적인 부상을 당할 우려가 있었다.On the other hand, in the above-described conventional seat belts, the seat belt is stopped in the event of a crash, so when the body of the driver, such as the driver is pushed forward by the inertia force, the seat belt is stopped is strong, especially the chest, such as the driver As a result of the pressure, the seat belt for safety acts inversely and the body could be fatally injured by the seat belt.
본 발명은 상기한 종래의 문제점을 감안하여 안출된 것으로, 본 발명의 목적은 충돌사고시 안전벨트에 의하여 신체에 가해지는 압박을 최소화하고 순간적인 충격을 완화시켜 주므로써 치명적인 부상을 예방할 수 있는 수단을 제공하는 데 있는 것이다.The present invention has been made in view of the above-mentioned conventional problems, and an object of the present invention is to minimize the pressure applied to the body by a seat belt during a crash accident and to mitigate momentary shocks, thereby providing a means for preventing a fatal injury. It is to provide.
이와 같은 목적을 달성하기 위하여 본 발명은 차체에 고정되어 안전벨트의 버클후단에 부착된 걸림구가 장착되는 장착구의 내부에 길이방향으로 외측으로 갈수록 높이가 점차적으로 높아지도록 다단의 걸림편을 형성시키고, 이 걸림편에 걸리는 상기 걸림구의 후단 양측에는 상기 양측 걸림편사이의 폭에 해당하는 위치에 소정의 힘을 받을 때 분리되는 절개부를 좌·우양측에 대칭되게 다단으로 형성시킨 걸림턱을 형성시켜서, 안전벨트가 소정의 인장력을 받을 때, 이 걸림턱이 걸림편에 순차적으로 접촉하면서 파괴되어 장착구에 끼워진 걸림구가 서서히 밀려나오면서 충격을 흡수하고 최종위치에서는 이탈이 방지되도록 하므로써 안전벨트의 길이가 약간 신장되면서 신체와 접촉할 수 있도록 한 자동차 안전벨트의 충격흡수장치를 제공한 것으로, 이하, 본 발명의 바람직한 실시예를 첨부된 도면에 의하여 상세히 설명하기로 한다.In order to achieve the above object, the present invention forms a multi-stage locking piece so that the height is gradually increased toward the outside in the longitudinal direction inside the mounting hole is fixed to the vehicle body is attached to the rear end of the buckle of the seat belt is mounted; On both sides of the rear end of the locking piece that is caught by the locking piece to form a latching jaw formed in multiple stages symmetrically on the left and right sides to separate the cut-off part when a predetermined force is applied at a position corresponding to the width between the two locking pieces. When the seat belt is subjected to a predetermined tension, the latching jaw is destroyed while sequentially contacting the seat, and the seating hole fitted into the mounting hole is gradually pushed out to absorb the shock and prevent the release from the final position. Is to provide a shock absorber of the automobile seat belt that allows the body to come into contact with the body slightly elongated. Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.
제1도는 본 발명의 일 실시예를 도시한 단면도로서, 본 실시예에서는 안전벨트(10)의 일단에 부착된 결합구(12)가 걸리는 버클(14)의 걸림구(15)가 차체(20)에 부착된 장착구(22)의 내부에 끼워져 고정되어지되, 상기 걸림구(15)의 후단에는 양측으로 걸림턱(16)이 형성되고, 장착구(22)의 내부에는 양측벽에 상기 걸림턱(16)이 걸리도록 외측으로 갈수록 높이가 점차적으로 높아지게 다단의 걸림편(24)이 형성된 것이다.1 is a cross-sectional view showing an embodiment of the present invention, in this embodiment, the locking hole 15 of the buckle 14 to which the engaging holes 12 attached to one end of the seat belt 10 is fastened. It is fitted into the inside of the mounting hole 22 attached to the fixed), but the locking jaw (16) is formed on both sides at the rear end of the locking hole 15, the inside of the mounting hole 22 on the both side walls In order to take the jaw 16 toward the outside, the height is gradually increased so that the multi-stage locking piece 24 is formed.
상기, 걸림구(15)의 후단 양측에 형성된 걸림턱(16)에는 상기 양측 걸림편(24)사이의 폭에 해당하는 위치에 소정의 힘을 받을 때 분리되는 절개부(18)를 좌·우양측에 대칭되게 다단으로 형성시킨 것이다.The left and right cutouts 18 which are separated when a predetermined force is applied to a locking jaw 16 formed at both rear ends of the locking port 15 at a position corresponding to the width between the two locking pieces 24 are left and right. It is formed in multiple stages symmetrically on both sides.
상기 걸림턱(16)에 형성된 절개부(18)는 안전벨트(10)에 소정힘 이상의 인장력이 걸릴 때 상기 장착구(22)의 걸림편(24)에 접촉되면서 파괴되도록 형성시켜서 정상적인 운행시에 발생할 수 있는 급정차시에는 파괴되지 않도록 하고, 충돌사고가 발생했을 경우에는 걸림구(15)의 당기는 힘에 의하여 외측으로부터 내측으로 차례대로 파괴되도록 하므로써 안전벨트(10)의 길이가 다단계로 서서히 신장되도록하여 충격을 흡수할 수 있도록 한 것이다.The cutout portion 18 formed on the locking jaw 16 is formed to be destroyed while contacting the locking piece 24 of the mounting hole 22 when a tension force greater than a predetermined force is applied to the seat belt 10. The length of the seat belt 10 is gradually extended in multiple stages by avoiding breakage during sudden stops, and in case of a crash, by breaking force from the outside to the inside by the pulling force of the catch 15. It is to be able to absorb the impact.
이와 같이 구성된 본 발명은 차량충돌직후, 안전벨트(10)의 신장이 정지되면서 운전자 등의 신체가 안전벨트(10)에 접촉하게 될 때, 이 부딪히는 힘이 소정한도를 넘게 되면 안전벨트(10)에 인장력을 부여하게 되는 것이고, 이 때 안전벨트(10)의 일단을 고정하고 있는 버클(14)은 제2도에 도시한 바와 같이, 장착구(22)에 고정된 걸림구(15)를 외측으로 당기게 되는 것이며, 걸림구(15)의 후단 양측에 형성된 걸림턱(16)은 장착구(22)양측에 형성된 걸림편(24)에 접촉하면서 외측의 절개부(18)로부터 내측의 절개부(18)까지 서서히 파괴되면서 외측으로 밀려나가게 되는 것이고, 이때 걸림편(22)에 형성된 절개부(18)은 상기 걸림편(24)에 의하여 차례대로 파괴되면서 시간을 지연시킴과 아울러 안전벨트(10)에 걸리는 인장력을 분할하여 흡수하게 되므로 운전자 등의 신체에 가해지는 압박을 감소시켜줌과 동시에 순간적인 충격을 완화시켜주게 되는 것이다.According to the present invention configured as described above, when the body of the driver or the like comes into contact with the seat belt 10 while the extension of the seat belt 10 is stopped immediately after the collision of the vehicle, the impact force exceeds the predetermined limit of the seat belt 10. In this case, as shown in FIG. 2, the buckle 14 fixing one end of the seat belt 10 has an outer side of the locking hole 15 fixed to the mounting hole 22, as shown in FIG. And the locking jaw 16 formed at both rear ends of the locking hole 15 is in contact with the locking piece 24 formed at both sides of the mounting hole 22, and the inner cutout portion is formed from the outer cutout 18. 18 to be slowly pushed out while being destroyed, and the cutout portion 18 formed on the locking piece 22 is delayed in time while being sequentially broken by the locking piece 24, and the seat belt 10 It absorbs by dividing the tension applied to the body Reducing the applied pressure would be dropped to relieve sikyeojum and momentary shock at the same time.
이처럼 본 발명은 버클이 장착되는 장착구내부에 걸림편을 형성시키고, 버클의 걸림구후단에 형성된 걸림턱에는 상기 걸림편에 접촉하여 다단계로 파손되는 절개부를 형성시켜서 된 것으로, 충돌사고시 버클의 장착구 양측에 형성된 걸림편이 걸림구의 걸림턱을 차례대로 파괴시키면서 외측으로 밀려나오도록 하므로써 안전벨트가 다단계로 신장되면서 순간적인 압박력을 감소시킬 수 있도록 한 것으로, 본 발명에 의하면 충돌사고시 안전벨트에 의하여 신체에 가해지는 압박을 최소화하고, 순간적인 충격을 완화시켜 주므로써 운전자 및 탑승자들이 안전벨트에 의하여 치명적인 부상을 당하게 되는 것을 방지할 수 있는 유용한 효과를 갖는다.As described above, the present invention is to form a locking piece in the mounting hole in which the buckle is mounted, and in the locking step formed at the rear end of the locking hole of the buckle to form a cut in contact with the locking piece in multiple stages. The locking pieces formed on both sides are pushed outwards while destroying the locking jaws of the locking holes in order to reduce the instantaneous pressing force as the seat belt is extended in multiple stages. By minimizing the pressure applied and mitigating momentary shock, the driver and passengers have a useful effect of preventing fatal injuries caused by the seat belt.
