Abstract

PURPOSE:To facilitate the escape of a crew from a car room when an accident occurs by automatically operating an unlocking bar hooking a clamp on the seat belt side in the unlocking direction with the power of a motor when a collision sensor detects the collision accident or the like of an automobile. CONSTITUTION:When a clamp 45 on the seat belt side is inserted into a lock case 3 while an unlocking bar 19 is protruded so that the tip section of the unlocking bar 19 of an operation mechanism in the lock case 3 does not interfere the operation of a locking bar 10, a locking piece 9 provided on the locking bar 10 is coupled with the hooking hole of the clamp 45, and the seat belt is kept in the fitted state. When a collision accident occurs in this fitted state and a collision sensor 22 generates an output signal, a motor 45 is started after the preset time (about 30sec). The unlocking bar 19 is moved to the left by the rotation of a screw shaft 27, its tip section 18 presses the tip section 7 of the locking bar 10, thus the locking piece 9 is released from the clamp 45, and the seat belt is released.

力による方式をとることもよい。Of the above configuration, the operating mechanism 20 will be described in detail. First, as shown in FIG.
An indexing method is adopted in which a screw shaft 27 is fitted onto the rotating shaft 26 of the locking rod 19 and is threaded through the body 28 of the unlocking rod 19.Secondly, as shown in FIGS. 7 and 8, A mounting bracket 29 is fitted to a shaft rod 30 installed on the partition wall 2 so that the elasticity of a spring 31 applies rotational force to the unlocking rod 32. On the other hand, as before,
A support plate 33 is installed on the lock case 3, a rotary plate 35 with a missing portion 34 cut out on the installation support plate 33, and a worm gear 36 are fitted onto a rotating shaft 39, so that the installation rotation shaft 39 can be freely rotated on the frame 38. Fits and supports. Next, as shown in FIG. 8, the motor 39 is placed on the support plate 33, the worm 41 is fitted onto the rotating shaft 40 of the installation motor 39, and the installation worm 41 is driven quickly by the worm gear 36. A lever system is used in which they are meshed in a rotational manner. In addition, thirdly, although not shown, a method using magnetic force may be used.

上記の作動速度について、使用のモーターを超低速回転
モーターを用いるか、モーターからの速動機構に大きく
減速装置を付加する場合は、タイマー２４は用いなくと
もよい。Regarding the above-mentioned operating speed, the timer 24 may not be used if a very low-speed rotating motor is used or if a large speed reduction device is added to the speed mechanism from the motor.

In the case of the index method, the distal end 18 of the unlocking rod 19 of the operating mechanism 20 is placed in a position that does not interfere with the operation of the locking rod 10.
Leave 9 sticking out.

後に、従来のシートベルトと同様に着用使用する。In addition, as shown in FIG. 7, in the case of the lever type, the tip end 42 of the unlocking rod 32 of the operating mechanism 20 is moved upward against the pressure of the spring 31 to a position that does not hinder the operation of the locking rod 10. As shown in FIG. 8, the protruding locking portion 43 of the unlocking rod 32 is brought into contact with the lower side surface 44 of the rotating plate 35, and the pressure of the spring 31 is suppressed to prevent rotation of the unlocking rod 32. Let it stop. At this time, when the rotary plate 35 rotates, the missing portion 34 of the rotary plate 35 is positioned on the side in the direction of rotation. Afterwards, it is worn and used in the same way as a conventional seat belt.

方向へ自然に離脱する。Next, if you are unfortunate enough to encounter a major collision while driving a car, the car may be seriously damaged, roll over, or catch fire. At the same time, the occupants may be seriously injured or lose their minds. In this case, you must immediately escape from the car or be rescued. Furthermore, when an accident occurs, the impact on the seatbelt worn is as great as the impact on the human body. This large impact is sensed by the sensor 22 of the device of the present invention and is transmitted to the switch 23, which turns on and causes current to flow. First, the motor 25 is started after an appropriate period of time elapses, preferably around 30 seconds, from when current flows through the timer 24 until the actuating mechanism 20 starts operating. First, in the case of the traction method, as shown in Figures 5 and 6, the motor 25
The threaded shaft 27 fitted onto the rotating shaft 26 rotates, and the threaded unlocking rod 19 slides in the direction of arrow R while remaining as it is. At this time, the distal end 18 of the unlocking rod 19 presses the distal end 7 of the locking rod 10, and the locking piece 9 is removed from the clasp 45 to which the belt is tied to the rear, thereby automatically unlocking the lock. Therefore, the clasp 45 naturally separates in the direction of arrow M.

９を外して自動解錠する。In the case of the lever type, as shown in FIGS. 7 and 8, the worm 41 fitted on the rotating shaft 40 of the motor 39 rotates, and at the same time as the worm gear 36 is engaged, the rotating plate is rotated as shown in FIG. 35 also rotates in the O arrow direction. At this time, the missing portion 34 of the rotary plate 35 similarly rotates, and when it comes into contact with the protruding locking part 43 of the unlocking rod 32 after one rotation, the locking force is lost and the locking rod 32 is removed, as shown in FIG. 32 is rotated by the centrifugal force of the spring 31, and the distal end 42 pushes down the distal end 7 of the locking rod 10 against the pressure of the spring 12, thereby removing the locking piece 9 from the clasp 45 and automatically unlocking the lock.

せるなどによる。As mentioned above, if we assume that the time from the occurrence of a collision to the point at which the situation has subsided and there is no risk of secondary disaster occurring is around 20 to 30 seconds, the lock will be automatically unlocked when that time has elapsed. Adjust to The method is 1. Set the timer. 2. Set the motor to extremely low speed. 3
．． This is done by using an intermediate speed reduction device that speeds up the movement from the motor to the unlocking rod.

次口、以上のような大事故の衝突でなく軽微な場合には
、人体は勿論のことシートベルトに加わる衝撃も小さい
ので、センサーは作動しないようにしてあるので自動解
錠されることはない。Next, in the case of a minor collision rather than a major accident like the one mentioned above, the impact on not only the human body but also the seatbelt is small, so the sensor is set not to activate, so the lock will not be automatically unlocked. .

以上のことから、従来のようなシートベルト着用により

し安心して用いられるようになった。Based on the above, we believe that the unfortunate situation where wearing a seatbelt in the conventional manner would result in the loss of precious human life in the event of a major accident where the seatbelt could not be easily released for self-evacuation or rescue, can be avoided. This problem has been solved by the present invention. Therefore, since there is no danger associated with wearing a seatbelt, the effect of wearing a seatbelt can be fully demonstrated, and the anxiety of wearing a seatbelt is eliminated, so that the seatbelt can be used with peace of mind.
