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 버틀후단에 부착된 걸림구가 장착되는 장착구의 내부에 길이방향으로 다단의 걸림편을 형성시켜 안전벨트가 소정의 인장력을 받을 때 이 걸림편이 순차적으로 파괴되면서 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 is fixed to the vehicle body to form a multi-stage locking piece in the longitudinal direction inside the mounting hole to be mounted on the rear end of the seatbelt of the seat belt when the seat belt receives a predetermined tensile force As the latching pieces are sequentially broken, the shock absorber of the seatbelt inserted into the mounting slot is gradually pushed out to absorb the shock and prevent the departure at the final position. With the provision of the device, a preferred embodiment 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 길이방향으로 양측벽에 상기 걸림턱(16)이 걸리는 걸림편(24)이 다단계로 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 is attached to the fixed), the locking end (16) is formed on both sides at the rear end of the locking hole 15, both sides of the mounting hole 22 in the longitudinal direction The catching piece 24 to which the catching jaw 16 is caught is formed in multiple stages.
상기 장착구(22)내벽의 양측에 형성된 걸림편(24)은 안전벨트(10)에 소정힘 이상의 인장력이 걸릴 때 파괴되도록 형성시켜서 정상적인 운행시에 발생할 수 있는 급정차시에는 파괴되지 않도록 하고, 충돌사고가 발생했을 경우에는 걸림구(15)의 당기는 힘에 의하여 차례대로 파괴되도록 하므로써 안전벨트(10)의 길이가 다단계로 서서히 신장되도록하여 충격을 흡수할 수 있도록 한 것이다.The locking pieces 24 formed on both sides of the inner wall of the mounting hole 22 are formed to be destroyed when a tension force greater than a predetermined force is applied to the seat belt 10 so as not to be destroyed during a sudden stop that may occur during normal driving. When a collision accident occurs, the length of the seat belt 10 is gradually extended in multiple stages so as to be destroyed by the pulling force of the locking hole 15 so as to absorb the shock.
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)을 파괴시키면서 외측으로 밀려나가게 되는 것이고, 이때 장착구(22)내면에 다단계로 형성된 걸림편(24)은 상기 걸림턱(16)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. It will be pulled out, the locking jaw 16 formed on both sides of the rear end of the locking hole 15 is to be pushed outward while destroying the locking piece 24 formed on both sides of the mounting opening 22, the mounting opening 22 The locking pieces 24 formed in the inner surface are delayed by the locking jaw 16 in order to be delayed in time, and are divided and absorbed by the tension force applied to the seat belt 10 so as to be applied to a body such as a driver. Reduces pressure and at the same time It will alleviate the shock.
이처럼 본 발명은 버클이 장착되는 장착구내부에 소정의 인장력이 가해질 경우에 파괴되는 걸림편을 길이방향으로 다단계로 형성시켜 충돌사고시 버클의 걸림구 양측에 형성된 걸림턱이 걸림편을 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 such, the present invention forms a multi-stage locking piece that is destroyed when a predetermined tensile force is applied to the inside of the mounting hole to which the buckle is mounted, while the locking step formed on both sides of the locking hole of the buckle in the event of a crash breaks the locking piece in sequence By being pushed outwards, the seat belt can be stretched in multiple stages to reduce the instantaneous pressing force. According to the present invention, the impact belt is minimized by the seat belt during a crash, and the momentary shock is alleviated. The driver and the passengers have a useful effect to prevent the fatal injury to the seat belt.
