Further, two spring plates 44 are attached to one of the indirect portions so that the other is provided with reversibility.

The inner band 38 attached to the seat 41 at one end is connected to the pedestal 12 that supports the entire mechanism described above.

[0026]

When using the seat belt of the present invention constructed as described above, first the projection rod 37 of the unlocking rod 9 is moved to the position shown in FIG.
As shown in FIG. 5, by pulling with a fingertip toward the locking rod 4 against the reducing force of the spring 18, at the same time, the spring stopper 27
The unlocking rod 9 is locked by and the traction force is always maintained.

When a seat belt of the present invention is worn and a collision accident occurs while the vehicle is running or a fall accident occurs in the water,
Alternatively, in the event of an aircraft crash, a strong impact is applied to the seat belt.

At this time, as shown in FIG. 8, the weight 31 of the pendulum oscillates greatly and tilts in the direction of the arrow s against the elastic force of the support by the momentum of the pendulum, and at the same time, the downward protrusion of the spring stopper 27 is caused. The navel 26 and the protruding portion 30 of the weight 31 that has been locked are displaced from each other and separated. At this time, the spring stopper 27 is reversed by the reducing force in the direction of the arrow r to be released from the hanging suspension arm 11 of the unlocking rod 9 and released.

Therefore, the released unlocking rod 9 is connected to the spring 18
It is pulled by the reducing force of t and moves in the direction of arrow t. At the same time, FIG.
As shown by 0 and 11, the piston shaft 21 connected to the unlocking rod 9 and the valve 23 at the tip thereof advance in the cylinder 19 while pushing the half solution 39 in the direction of arrow t.

At this time, the valve 23 is provided with the ultrafine pores 40, or
A gap is provided between the inner surface of the cylinder 19 and the valve 23 to allow the movement of the solution and appropriately control the progress of the piston shaft 21.

May interfere with the progress of the, and sometimes stop. In order to prevent such a situation, the cap 20 bulges outward to prevent an increase in pressure.

In this case, it is possible to prevent an increase in pressure by extending the tip end portion of the piston shaft 21 and providing a projecting guide shaft 45 drawn by an imaginary line and projecting it in the advancing direction. There is a drawback that is impossible. In this respect, the method using the cap 20 of the present invention is effective.

In this way, while the damper is being braked, the unlocking rod 9 is retracted by the tension of the spring 18, and the tip portion 7 is also retracted. At this time, the inclined portion 8 is retracted, as shown in FIG. Since the tip end portion 10 of the locking rod 4 is pushed and rotated in the direction of the arrow d, and when it is lowered by the dimension m, it is detached from the suspension alloy tool 3, so that the seat belt is removed.

In addition, in the case where the wearer mistakenly applies a force to laterally bend the clasp 1 to the plate-shaped inner band 38 of the bearing, even if the wearer bends once, The original natural state can be restored by the elasticity of rubber or the reducing force of the spring plate sandwiching the other side.

[0035]

The method of use of the present invention is to be worn in the same manner as a conventional seat belt when driving or riding in a car.

If the vehicle accidentally encounters a collision accident while the vehicle is running, the vehicle may be seriously damaged, overturned, or fired. At the same time, drivers and passengers often fall into the worst situation of being severely injured or fainted by an impact. Or, if it falls into the water such as the sea or river, it will be in a dangerous state. The same applies in the case of an aircraft crash.

Under the worst conditions as described above, even after the seat belt has stopped moving even if the seat belt is complicatedly entangled with the body or in a confused mental state,
When there is no danger of a secondary disaster, for example, 10
Adjustment is made by the pulling force of the spring 18 and the concentration of the half solution in the cylinder 19 so as to be automatically released after an appropriate time of about 15 seconds from the second.

When the lock 18 is once unlocked due to an accident or the like, as shown in FIG. 9, the protruding rod 37 of the unlocking rod 9 protruding from the retainer 1 is opposed to the reducing force of the spring 18. Then, pull with your fingertip in the P direction where the suspension alloy tool 3 and the locking rod 4 connected to the outer band are located. At this time, as shown in FIG. 7, by pulling the lower end of the hanging suspension arm 11 beyond the position where it is locked by the spring stopper 27 by n dimension, as shown in FIG.
Push the protruding piece 35 of the spring stopper 27 at the lower end of 1,
It causes the burnest top 27 against its elasticity. At the same time, since the weight 31 of the pendulum is no longer in the way, the reducing force of the support 33 returns it to the original position in the y direction.

Therefore, when the finger is removed, the hanging suspension arm 11
Is pulled by the spring 18 contrary to the above, is stopped by being stopped by the n-dimensional return spring stopper 27, and the setting of the unlocking rod 9 is completed with one touch.

In addition, the present invention can be applied and used when the seat belt is used in vehicles other than automobiles and aircraft.

[0041]

Since the present invention is configured as described above, it has the following effects.

Even when a vehicle crashes into a car or falls into the water while the vehicle is traveling, the seat belt is automatically released when the risk of a secondary disaster disappears after the accident.
As a result, it became easier to escape by himself, and it became easier to rescue him regardless of the amount of retained money on the other side of the window, so the situation of fatal accidents due to delayed escape or delayed rescue was eliminated.

Further, after the present invention is activated, there is a convenience that it can be easily set again with one touch in about one second.

In addition, since the present invention does not have a sophisticated electronic device or electric wiring, it does not happen that the seat belt cannot be removed due to a trouble in the event of an accident.

As a result of the above, even a person who has not worn the conventional seat belt due to the fear of wearing it can feel comfortable wearing it.

Adjustment is made by the pulling force of the spring 18 and the concentration of the half solution in the cylinder 19 so as to be automatically released after an appropriate time of about 15 seconds from the second.

When the lock bar is once unlocked due to an accident or the like, as shown in FIG. 9, the projection rod 37 of the unlocking rod 9 protruding from the fastener 1 is opposed to the reducing force of the spring 18. hand,
Pull with your fingertip in the P direction where the suspension alloy tool 3 and the locking rod 4 connected to the outer band are located. At this time, as shown in FIG. 7, by pulling the lower end of the hanging suspension arm 11 beyond the position where it is locked by the spring stopper 27 by n dimension, the lower end of the hanging suspension arm 11 is drawn as shown in FIG. Pushes the projection piece 35 of the spring stopper 27 to cause the spring stopper 27 against the elasticity. At the same time, since the weight 31 of the pendulum is no longer in the way, the reducing force of the support 33 returns it to the original position in the y-arrow direction.

Therefore, when the finger is removed, the hanging suspension arm 11
Is pulled by the spring 18 contrary to the previous step, returned by n dimension, stopped by being stopped by the spring stopper 27, and the setting of the unlocking rod 9 is completed with one touch.

In addition, the present invention can be applied and used when a seat belt is used in vehicles other than automobiles and aircraft.

[0043]

Since the present invention is configured as described above, it has the following effects.

Even in the case of an accident such as a collision or a fall into the water while the vehicle is traveling, the seat belt is automatically released when the danger of the secondary disaster disappears after the accident.
As a result, it became easier to escape by himself, and it became easier to rescue him regardless of the amount of retained money on the other side of the window, so the situation of fatal accidents due to delayed escape or delayed rescue was eliminated.

Further, after the present invention is activated, there is a convenience that it can be easily set again with one touch in about one second.

Next, in the conventional seat belt, when a strong force is accidentally applied to the place where the inner band 38 attached to the seat is plate-shaped, the inner band 38 is folded.
Since it is strong and does not bend, its force inevitably transfers to the fastener 1 and destroys the button 46 and the lock box 5 shown in FIG. 1 that are pushed during unlocking, causing an accident. However, the present invention was able to prevent the occurrence of an accident in such a situation.

In addition, according to the present invention, since there is no sophisticated electronic device or electric wiring, there is no failure such as poor contact, so that there is no problem when an accident occurs and the seat belt does not come off.

As a result of the above, even a person who does not wear a conventional seat belt due to a fear of wearing it can feel comfortable wearing it.

Claims (3)

[Claims] 1. A locking rod for connecting and disconnecting a hanging alloy tool for connecting with an outer band is provided inside a clasp of a seat belt, and a locking rod is provided so as to be freely engaged with and disengaged from the hook. An unlocking rod is provided, which has a claw portion in which an inclined portion is formed by bending the portion into two parts and which is bent, and a suspending arm is hung on the middle abdomen. On the other hand,
A slide holding box is provided at the rear of the unlocking rod, and a hollow portion formed in the slide holding box is slidably inserted back and forth with the rear portion of the unlocking rod facing the locking rod. Also, the spring is tensioned so that the unlocking rod is always pulled in the direction of releasing the locking rod. Further, a cylinder is attached to the inside of the slide holding box, one longitudinal end of the cylinder of the cylinder is perforated, and a flexible cap such as rubber is fitted to the other end. Next, a piston shaft whose one end is connected to the suspension arm of the unlocking rod is provided,
A dish-shaped valve is fitted to the other end of the piston shaft, and this portion is slidably fitted back and forth in the cylinder. On this occasion,
A seatbelt unlocking adjustment device, which is equipped with a damper for decelerating the unlocking speed, which is filled with a half-mixed solution such as silicon oil when the cap is fitted inside the cylinder. 2. A protrusion, which is engageable with and disengageable from a hanging suspension arm of an unlocking rod, is provided above the tip at a suitable position on the base.
A spring stopper with a downwardly projecting navel is fixed at the rear end. Further, a recess is bored in the upper portion, a weight having a protruding portion is provided in the center, a bearing arm having one end fixed at the same position as the spring stopper is provided on the other, and a rubber is provided at the tip of the bearing arm. A cylindrical or columnar support is provided with plastic, a coil spring, or the like, and a pendulum is provided on which the weight is supported so that it can swing freely. At this time, the lower end of the navel protruding downward from the previous spring stopper and the upper end of the protruding portion inside the recess of the weight are butted against each other, and the pendulum swings and separates when an impact is received from the outside. Then, in addition to the mechanism of the spring stopper with the impact sensor that releases and releases the spring stopper that has locked the unlocking rod, the protrusion at the back of the previous spring stopper hits the lower end of the hanging suspension arm of the unlocking rod. On the other hand, a projecting rod is vertically inserted into the back of the unlocking rod so that the head of the upper end protrudes out of the lock box of the clasp. Then
A device that makes it possible to set with a one-touch operation of pulling the protruding rod in the direction of the locking rod against the reducing force of the spring, and at the same time locking the unlocking rod with the spring stopper so that the pulling force is always retained. 3. The other end of the inner band having a plate-shaped cross section supporting a clasp is cut before being attached to a seat and alternately cut and wound,
After combining these, the pins are rotatably inserted and pivotally connected in a hinged manner. Further, the indirect portion is covered with elastic rubber or the like to have reversibility. Further, one of the indirect parts is attached to the other by sandwiching the other with two spring plates to provide reversibility. As a result, the inner belt is restored by an external force even if it bends once. Due to this, the structure of the inner band for preventing the damage of the retainer bearing that prevents damage to the retainer part and eliminates seat belt accidents in advance.
