Generally, a seat belt is installed on the seat of a car to protect the driver from the impact of an accident. Particularly in recent years, with the rapid increase in the number of automobiles, the number of automobile accidents has also continued to increase, and it has been strongly urged that seat belts be fastened. Recently, the use of seatbelts has become mandatory by law to ensure that all vehicles are worn.

However, despite the fact that seatbelts are compulsory to wear, the reality is that many people do not wear them because they are a hassle. has set penalties to ensure that they are worn.

[Problem that the invention attempts to solve]

However, if a car is driven without wearing a seatbelt as described above, it will not be possible to sufficiently ensure the safety of the driver in the event of an accident, but the enforcement side will When encouraging people to fasten their seat belts in order to prevent accidents, there is a problem in that it is difficult to visually confirm whether the seat belt is fastened from outside the vehicle, especially at night.

This invention is an attempt to improve the above-mentioned problems by providing a structure that makes it possible to confirm whether or not the seat belt is fastened from outside the vehicle, thereby ensuring that the seat belt is fastened. The problem to be solved lies in making it possible to do so.

That is, the present invention is characterized in that the wearing state of the seat belt can be confirmed by the light emitting state of the seat belt.The specific means and operation thereof are as follows. be.

[Means for solving problems]

A pair of short belts and long belts are extended from the left and right sides of the seat, and a buckle (receiving metal fitting) is connected to the short belt, and a plate (insertion metal fitting) is connected to the long belt, and the plate is connected to the buckle. In an automobile seat belt that is provided so as to obtain a locked state by being inserted into the belt, optical fibers are woven along the length of a long belt attached to a plate. The optical fiber is made of a transparent material and has a polygonal cross section, and its outer surface is alternately provided with reflective surfaces that reflect light and transmission surfaces that transmit light.

A light emitter is disposed on the plate so as to face the long belt.

A terminal is provided on the buckle so that it can be connected to the light emitting body by attaching and detaching the plate to the buckle, and a power source is connected to the terminal.

consists of a pair of left and right belts, that is, a long belt 6A that connects one end to the right side (door side) of the seat and a short belt 6B that connects one end to the left side (console box side) of the seat. The other end of 6A extends upward and is telescopically connected to the side frame of the automobile, although not shown. Further, an appropriate number of optical fibers 7 are woven into the long belt 6A along its longitudinal direction. The optical fiber 7 is made of a transparent material and has a regular polygonal cross section, and has a reflective surface 7A that reflects light on its outer surface.
Transmissive surfaces 7B that transmit light are provided alternately. More specifically, a reflector 8 that reflects light is fixed to the reflective surface 7A of the optical fiber 7.

Then, one of the lock fittings, that is, the plate 9, is inserted into the middle of the long belt 6A. The same plate 9 is the long belt 6A mentioned above.
A plate main body 9A having insertion holes 10 and 11 and formed in a substantially Japanese letter shape, and an engagement piece 9B extending from the tip of the plate main body 9A and having an engagement hole 12 for a lock piece to be described later. The plate body 9A consists of
A transparent synthetic resin film 13 is applied to the surface of the resin mold by a resin mold, and the synthetic resin film 13
A light emitter 14 is buried inside. More specifically, the light emitting body 14 is disposed along a bracket 9A' extending horizontally in the middle of the plate main body 9A,
The terminals 15 and 16 of the light emitter 14 are connected to the engaging piece 9B.
The synthetic resin film 13 is provided so as to protrude from the synthetic resin film 13 in the extending direction.

Further, the other lock fitting, that is, a buckle 17 is connected to the short belt 6B. The buckle 17 is formed in the shape of a thin rectangular box, and the buckle 17 is provided with an insertion hole 18 formed in the shape of a long hole with an opening at its upper edge.
Further, although not shown in the drawings, a lock piece is attached to the buckle 17 so as to be movable forward and backward in correspondence with the engagement hole 12 of the engagement piece 9B, and the engagement piece 9B can be inserted into the insertion hole 18. Thus, the lock piece is provided so as to be able to engage with the engagement hole 12, that is, to obtain a locked state. And again,
