Abstract

PURPOSE: A shock absorbing device of a safety belt is provided to improve the operational performance thereof by smoothly moving a buffer rod and a guide rod upward because oil blocked by the buffer rod moves through a fluid moving hole of the guide rod. CONSTITUTION: A shock absorbing device of a safety belt comprises a body part(10), multiple blocking ribs(14), and a buffer rod(16). Oil(O) is charged in a hollow inside of the body part, and multiple parts are embedded in the body part. The multiple blocking ribs are arranged inside the body part and are protruded toward the inner side of the body part. The buffer rod is installed in the body part and vertically moves. If the buffer rod is positioned in the multiple blocking ribs by external shock, the moving speed of the buffer rod successively decreases. The buffer rod comprises a guide rod(22) and a fluid moving hole(26).

Description

Seat shock absorber {A shock absorber of seat belt}
The present invention relates to a seat belt shock absorber, to a seat belt shock absorber to minimize the pressure applied to the body by the seat belt.
In general, seat belts in a car are subject to secondary collisions when drivers and passengers are hit by solid objects such as steering wheels, dash panels, and windshields in front of the car, or they may come out of the windshield. It has a function to prevent death or injury due to the accident, and such a seat belt is freely stretchable during a sudden stop in a normal state or when a driver and a passenger occupy the body inside, and an abnormal sudden deceleration and crash accident In the sudden deceleration caused by the elongation of the seat belt is stopped is provided with a device that can prevent the body, such as the driver to be pushed forward.
On the other hand, in the seat belt, 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 of which the kidney is stopped is pressed by a strong force, particularly the chest. As a result, the seat belt for safety acts inversely, and the body may be fatally injured by the seat belt.
Therefore, an object of the present invention is to solve the problems of the prior art as described above, the oil-filled seat belt shock absorbing device is operated by hydraulic pressure, a plurality of blocking ribs are installed inside the body portion, When the buffer rod is located between the blocking ribs to provide a seat belt shock absorber to buffer the shock tension of the seat belt by sequentially reducing the moving speed of the buffer rod.
According to a feature of the present invention for achieving the object as described above, the seat belt shock absorbing device according to the present invention, the body portion is filled with a plurality of parts and the oil is filled in the hollow interior, the inside of the body portion It is provided with a plurality of blocking ribs protruding in the inward direction of the body portion, and installed to move up and down inside the body portion and is located in the plurality of blocking ribs by an external impact to sequentially reduce the moving speed It includes a buffer rod.
On both sides of the buffer rod, the guide rod for guiding the up and down movement of the buffer rod, and formed through the lower portion of the guide rod, the fluid transfer hole for guiding the movement of oil when the guide rod is moved up and down It includes.
The upper portion of the body portion, the buffer rod and the guide rod is installed therein further includes an upper cover for guiding the movement of the buffer rod and the guide rod.
The lower part of the body portion, the oil is filled therein and includes a lower cover to cover the lower portion of the body portion.
It is provided between the body portion and the upper, lower cover, characterized in that it further comprises an upper, lower gasket of elastic material to prevent leakage of oil flowing between the body and the upper, lower cover.
Seat belt shock absorber according to the present invention has the following effects.
In the present invention, the oil is filled in the body portion is operated by hydraulic pressure, a plurality of blocking ribs are installed in a position spaced upward in the body portion. When the buffer rod is positioned between the blocking ribs, the movement speed of the buffer rod is sequentially reduced. Therefore, immediately after the collision of the vehicle, the driver's body is pressed by the seat belt while the extension of the seat belt is stopped. When a predetermined or more impact tension is applied to the seat belt, the shock absorbing rod is moved upwards, and the feeding speed is sequentially reduced by the blocking ribs, thereby reducing the pressure applied to the body and simultaneously relieving the instantaneous shock.
In addition, guide rods are installed at both sides of the buffer rod to guide the vertical movement of the buffer rod, and a fluid movement hole is formed in the guide rod so that the oil blocked by the buffer rod is moved through the fluid movement hole. The upper movement of the rod and the guide rod smoothly has the advantage that the operating performance is improved.

To combine.
Mounting and fixing the coupler (3) to the buckle (5). When the vehicle is suddenly stopped or an occupant is bounced forward by inertia, the extension of the belt 2 is stopped by the locking device of the seat belt. Elongation of the belt 2 is stopped and a predetermined or more impact tension is applied.
Therefore, when the oil (O) is filled in the interior of the body portion 10 and a tension below a predetermined pressure is applied by hydraulic pressure, the connecting portion 30 does not move upwards, and when the predetermined or more impact tension is applied, the buckle portion The connecting portion 30 combined with (5) is moved upward. When the connection portion 30 is moved to the upper portion, the buffer rod 16 and the guide rod 22 of the body portion 10 which is operated by hydraulic pressure by filling the oil O are moved upward.
The blocking plate 18 provided at the lower portion of the buffer rod 16 is moved, and the blocking plate is formed in a plurality of blocking ribs 14 formed in the buffer rod hole 12 according to the movement of the upper portion of the blocking plate 18. 18 is located. When the blocking plate 18 is located in the blocking rib 14, the upper movement of the buffer rod 16 is decelerated.
In addition, a plurality of blocking ribs 14 are formed on the inner circumferential surface of the buffer rod hole 12, and the blocking plate 18 is positioned in the blocking rib 14 as the upper portion of the blocking plate 18 moves. In order to reduce the moving speed of the buffer rod 16 in order to tension the belt (2) sequentially.
Therefore, when the vehicle is suddenly stopped or a collision accident of the vehicle occurs, the belt 2 is sequentially tensioned to gradually decelerate the body's bouncing forward to alleviate the impact tension of the belt.
Guide rods 22 are installed on the left and right sides of the buffer rod 16. The guide rod 22 is moved upward when the buffer rod 16 is moved upward to support left and right sides when the buffer rod 16 moves up and down.
The guide rod 22 is provided inside the guide rod hole 20, and the guide rod 22 is moved up and down along the guide rod hole 20. A guide plate 24 is installed below the guide rod 22. The outer diameter of the guide plate 24 is formed to the same size as the inner diameter of the guide rod hole 20 to guide the guide rod 22 to move vertically up and down.
A fluid movement hole 26 is formed on the outer circumferential surface of the guide plate 24 so as to penetrate up and down. When the guide plate 24 is moved up and down, the filled oil O is filled with the fluid movement hole ( 26 to be moved through to smooth the up and down movement of the guide plate 24.
That is, the shock absorbing rod 16 and the guide rod 22 are coupled to the connecting portion 30 and the connecting portion 30 is moved upward when a predetermined or more impact tension is applied to the belt 2. Accordingly, the buffer rod 16 and the guide rod 22 coupled to the connection part 30 are transferred upward, and when the buffer rod 16 is positioned on the blocking rib 14, the fluid movement hole ( The oil O is conveyed from the upper part to the lower part through the 26, and the buffer rod 16 and the guide rod 22 are conveyed upward at a low speed.
After being operated by the collision and sudden stop of the vehicle, the user can press the connection part 30 downward to return to the original position and reuse it.
