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 최소화 하고 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 the seat belt in the event of a crash and to mitigate the instantaneous impact by means of preventing a fatal injury It is to provide.
이와 같은 목적을 달성하기 위하여 본 발명은 좌,우양측에 안전벨트 인출구가 형성되고 내측의 상,하부에는 상호 소정의 간격으로 안전벨트가 끼워지는 걸림고리가 교차되게 형성된 함체의 내부에 안전벨트를 지그재그로 설치하여 안전벨트에 소정힘 이상의 인장력이 걸리게 될 경우, 상기 함체내부의 상,하부에 형성된 걸림고리가 파손되면서 안전벨트가 직선으로 펼쳐지면서 신장되도록 한 것으로, 이하, 본 발명의 바람직한 실시예를 첨부된 도면에 의하여 상세히 설명하기로 한다.In order to achieve the above object, the present invention provides a seatbelt outlet on left and right sides, and a seatbelt inside the enclosure in which upper and lower portions of the inner side of the inner body are formed to intersect a catch ring in which safety belts are fitted at predetermined intervals. When installed in a zigzag to take a tensile force of more than a predetermined force on the seat belt, the locking ring formed in the upper and lower portions of the inside of the enclosure is broken, so that the seat belt is stretched in a straight line, hereinafter, preferred embodiments of the present invention It will be described in detail by the accompanying drawings.
제1도는 본 발명의 일 실시예를 도시한 것으로, 본 실시예에서는 함체(12)의 좌,우 양측에는 인출구(12a,12b)가 형성되고 내측의 상,하부에는 각각 소정의 간격으로 복수의 걸림고리(14,16)가 교차되게 형성된 것이며, 이 함체(12)내부에는 안전벨트(10)가 상기 걸림고리(14,16)에 교차되게 끼워져 지그재그식으로 설치된 것이다.FIG. 1 illustrates an embodiment of the present invention. In the present embodiment, the outlets 12a and 12b are formed at both the left and right sides of the enclosure 12, and the upper and lower portions of the housing 12 are provided at predetermined intervals, respectively. The hooks 14 and 16 are formed to cross each other, and the seat belt 10 is installed in a zigzag manner to fit the seat belt 10 to the hooks 14 and 16.
상기 함체(12)내측의 상,하부에 형성되는 걸림고리(14,16)는 안전벨트(10)에 소정힘 이상의 인장력이 가해지게 되면 파손될 수 있도록 한 것으로, 정상적인 상태에서는 안전벨트(10)가 함체(12)내에서 소정길이만큼 접혀진 상태를 유지하도록 한다.The hooks 14 and 16 formed in the upper and lower portions of the inside of the enclosure 12 are to be damaged when a tensile force of a predetermined force or more is applied to the seat belt 10, and the seat belt 10 is normally in a normal state. It is to maintain the folded state by a predetermined length in the enclosure (12).
이와 같이 구성된 본 발명은 소정길이의 안전벨트(10)를 함체(12)내에 접어 넣은 것과 같은 상태가 되는 것이며, 충돌사고시에는 안전벨트(10)에 순간적으로 큰 장력이 걸리게 되므로써 함체(12)내부의 걸림고리(14,16)가 파손되게 되어 함체(12)내에 접혀져 있던 안전벨트(10)가 밖으로 풀리게 되면서 안전벨트(10)가 소정의 길이만큼 신장되는 것이다.The present invention configured as described above is in a state in which the seat belt 10 of a predetermined length is folded into the enclosure 12, and in the event of a collision, the seat belt 10 is momentarily subjected to a large tension, thereby causing the interior of the enclosure 12 to be closed. The hooks 14 and 16 are damaged so that the seat belt 10 folded in the housing 12 is released and the seat belt 10 is extended by a predetermined length.
이처럼 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, 이때 함체(12)내에 접혀져 보관되어 있던 안전벨트(10)가 풀려 함체(12)밖으로 당겨져 나오게 되어 안전벨트(10)에 걸리는 인장력을 흡수함과 아울러 안전벨트(10)의 길이가 약간 신장되므로써 운전자 등의 신체에 가해지는 압박을 감소 시켜줌과 동시에 순간적인 충격을 완화시켜주게 되는 것이다.As described above, the present invention is a tension force to the seat belt 10 when the impact force exceeds a predetermined limit when the body such as the driver comes into contact with the seat belt 10 while the extension of the seat belt 10 is stopped immediately after the vehicle collision. In this case, the seat belt 10 that is folded and stored in the enclosure 12 is released and pulled out of the enclosure 12 to absorb the tensile force applied to the seat belt 10 and the seat belt 10 of the seat belt 10. As the length is slightly increased, the pressure on the body of the driver and the like is reduced, and at the same time, the momentary shock is alleviated.
이상 설명한 바와 같이 본 발명은, 소정길이의 안전벨트를 함체내의 걸림고리에 끼워 넣어, 정상적인 성태에서는 안전벨트가 밖으로 당겨져나오지 않도록 하고, 충돌사고시에는 안전벨트에 순간적으로 걸리게 되는 큰 장력에 의하여 걸림고리가 파손되면서 함체내에 접혀져 있던 안전벨트가 밖으로 풀리도록 한 것으로, 본 발명에 의하면충돌사고시 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, in the present invention, a seat belt of a predetermined length is inserted into a hook in an enclosure so that the seat belt is not pulled out in a normal state, and caught by a large tension that is momentarily caught by the seat belt in a crash event. Safety belts folded in the enclosure while the ring is broken to be released, according to the present invention minimizes the pressure applied to the body by the seat belt in the event of a crash and mitigates a momentary shock to the driver and passengers It has a useful effect that can prevent the belt from being fatally injured.
