Description

In the present invention, for example, the state of attachment / detachment (attachment or detachment) of a seatbelt for each seat of a vehicle such as a bus can be confirmed from at least the driver side, and further, for each seat in the event of a traffic accident. The seatbelt attachment / detachment status is saved to enable more accurate analysis of the seatbelt attachment / detachment status at the time of an accident and the cause of the accident after the accident, and fulfill the obligation to encourage the driver to fasten the seatbelt. It relates to a new seatbelt attachment / detachment status confirmation device that can confirm the presence / absence.

Buses that cause injuries and deaths, especially traffic accidents of vehicles such as large buses and automobiles, occur frequently and cause serious social problems. Traffic accidents can be reduced by observing road traffic regulations and maintaining safe speeds, but in reality they occur for various reasons and are not completely eliminated.
Therefore, it is necessary to make efforts to eliminate traffic accidents as much as possible, but at the same time, it is also necessary to make efforts to reduce the damage caused by accidental death and injury in the event of a traffic accident, which is the seat belt of passengers. Thorough wearing is extremely effective.

By the way, for example, according to a large bus crash test conducted by the United States Department of Transportation's Highway Traffic Safety Bureau, dummy dolls without seatbelts are blown away and cause serious damage such as death or serious injury. It is clear that there is a strong possibility that the accident will occur, but all the dummy dolls wearing seat belts stayed in the seats, and it became clear that the damage caused by the accident is likely to be minor.
From June 1, 2008, the revised Road Traffic Law requires that all seats of vehicles be fastened with seat belts.

However, when the rear seat belt is not fastened, the administrative sanction is only for those on the highway, and the non-wearing of the seat belt other than the highway is not subject to the administrative sanction. The reality is that they are not thoroughly worn.
In addition, the reality that there are no penalties for passengers who do not fasten their seatbelts even if the driver, tour operator, or other crew member calls for them to wear them is also a cause of incomplete seatbelt wearing. Then, a major accident of 15 fatalities and 26 injured due to the bus crash, which is thought to be the cause, occurred on January 15, 2016 at Usui Bypass on Route 18. That is the so-called "Karuizawa bus tour accident".

Some passengers on the bus testified that "there were passengers who were not wearing (non-fastened) seat belts, and were not instructed to wear them." It was pointed out that there were only a few people with wearing marks, and that if all of them were wearing (wearing) firmly, there would have been more lives saved and more injured.
Therefore, the bus operator, the driver, and other crew members may be liable not only for the occurrence of a fall accident but also for the failure to fulfill the obligation of the driver to wear a seatbelt. Of course, even if other automobiles are responsible for the accident and their own bus is not responsible for the accident, if human damage occurs on the bus, the obligation to urge them to fasten their seat belts will be fulfilled. Failure to prove may result in civil and, in some cases, criminal liability for failure to perform.

However, it is possible to detect the wearing state of the seatbelt (either the wearing state or the non-wearing state) and display the detection output so that the wearing of the seatbelt can be prompted by visually recognizing the detection result. The technology has already begun to be developed.
One of the results is a seatbelt wearing display device that can display the seatbelt wearing state in both the driver's seat and the passenger's seat of the vehicle so that it can be visually recognized from the outside of the vehicle and effectively encourage the occupants to wear the seatbelt. (Japanese Patent Laid-Open No. 11-321562: Patent Document 1).
According to such a seatbelt wearing display device, the state of wearing the seatbelt in the driver's seat and the passenger's seat in the car can be monitored by other people or police officers outside the car, and in the case of not wearing it. It can be said that wearing can be encouraged.

Further, a occupant number detecting means for detecting the number of occupants and a belt wearing number detecting means for detecting the number of seatbelts worn are provided, and the number of occupants detected by the occupant number detecting means is detected by the seatbelt wearing number detecting means. A vehicle seatbelt warning device has also been proposed that recognizes that there are occupants without seatbelts and issues a warning prompting them to fasten their seatbelts when the number of seatbelts is greater than the number of seatbelts worn (Japanese Patent Laid-Open No. 2016-7919). Publication: Patent Document 2).
According to such a vehicle seatbelt warning device, when the number of occupants and the number of seatbelts worn match, the number of non-fastened seatbelts can be recognized as "0", so no warning is issued and the number of occupants increases. When the number of seatbelts is larger than the number of seatbelts worn, it can be recognized that the number of non-fastened seatbelts is "1" or more, so it can be said that the seatbelt wearing number can be warned.

However, in the conventional technique, including the techniques described in Patent Documents 1 and 2, the driver cannot grasp the seatbelt attachment / detachment (attachment / detachment) status for each seat for all seats in the vehicle, and the driver does not wear it. There is a problem that it is not possible to issue a warning to identify a seat and urge you to fasten a seatbelt, and there is a problem that it is not possible to keep a record of the seatbelt attachment / detachment status for all seats in the event of a traffic accident. Was.
First, the problem that it is not possible to issue a warning to identify a non-wearing seat and prompt the user to wear a seatbelt will be described.
Buses, especially large buses, have a large number of seats and it is difficult to distinguish between seats with and without seatbelts, so there is a warning that the driver should identify passengers with non-seat belts and wear seatbelts. Can not. In many cases, a warning that does not involve the identification of a non-wearing seat does not have a sufficient warning effect.

The reason is that, as mentioned above, there are many passengers who do not want to fasten their seat belts even if the crew members such as drivers call for them. Therefore, if there are people who do not fasten their seatbelts, even if the driver announces that "There are people who do not fasten their seatbelts. Please wear them as soon as possible", they do not wear the seatbelts without recognizing themselves. There are many cases where the state of is continued.
In this case, if it is possible to identify a seat in which the seatbelt is not fastened and warn that the seatbelt is not fastened, it is possible to surely encourage the seatbelt to be fastened. For example, if the driver announces, "Customers with seats in rows ○ and □. The seat belts are not properly worn. Please wear them. We will depart when the wearing is confirmed." Most passengers Is to wear a seat belt.
However, in the past, there was no means for the driver to recognize a seat without a seatbelt, and it was not possible to identify the seat and issue a warning to passengers without a seatbelt.

Next, in the unlikely event that a traffic accident occurs, the problem of not being able to keep a record of the seatbelt attachment / detachment status for all seats at the time of the accident will be described.
In the unlikely event that a traffic accident occurs, it is necessary to clarify the cause of the subsequent traffic accident, but in that case, the seatbelt attachment / detachment status for each seat is also an important material for investigating the cause.
In addition, bus operators and bus drivers are pursued not only for their liability for traffic accidents, but also for their negligence regarding the obligation to confirm the wearing of seat belts and the obligation to warn non-wearers.
In that case, there is no means to prove whether or not the obligation has been fulfilled, such as checking the seatbelt attachment / detachment status by the driver, and the passenger's testimony is used as an important material, resulting in excessive criminal and civil liability. There is a possibility of incurring.
In other words, even if the passenger's testimony is based on an ambiguous memory, or if the passenger has a memory error due to the shock of an accident, etc., the bus operator and the bus driver are liable excessively because there is no means of proof. This is because there is a possibility that it will be lost.
In addition, there was a risk that the credibility of bus operators' safety efforts would be lost and the business results would be adversely affected.

Therefore, the first object of the present invention is to enable the driver to grasp the seatbelt attachment / detachment status for all seats of a vehicle such as a bus in association with the seat address, and secondly, in the unlikely event of traffic. Even if an accident occurs, the purpose is to be able to check the seatbelt attachment / detachment status of all seats in each seat immediately before the accident after the accident.
