In order to reduce the number of automobile accidents, it is important to adhere to road traffic regulations and to drive at a safe speed. Nevertheless, traffic accidents are encountered for some reason. There are cases. For this reason, in order to reduce injuries to the occupants of the vehicle in such a traffic accident, the seats of the vehicle must be equipped with seat belts as occupant restraint devices. But it is mandatory.

[0004] However, the wearing rate of the seat belt is not 100% when the vehicle is running. In particular, when the driver wears the seat belt, the wearing display function (lighting of the belt warning lamp) on the instrument panel of the car is required. Although the seat belt is considerably high due to some reasons, the seat belt wearing of the passenger seat is not so high at present because the function of displaying the seat belt of the passenger seat was not provided conventionally.

SUMMARY OF THE INVENTION The present invention has been made in view of the above points, and shows a seat belt wearing state for both a driver's seat and a passenger seat, and can effectively encourage an occupant to wear a seat belt. It is an object to provide a display device.

And a control unit for lighting and displaying the wearing state of the user.

[0007]

In the seat belt wearing display device having such a structure, the belt wearing detecting means detects the wearing of the seat belts in the driver's seat and the passenger seat, and the control means detects the detection signal from the belt wearing detecting means. On the basis of the above, control is performed so that the wearing state of the seat belts of the driver's seat and the passenger's seat is lighted on the belt wearing display means. As a result, the belt-attached display means disposed outside the automobile illuminates and displays the wearing state of the seat belts in the driver's seat and the passenger's seat.

[0008] Since the belt wearing display means can be visually recognized from a remote position outside the automobile, it is possible for a driver or a passenger in a passenger seat to determine whether or not a seat belt is worn by others or the police. The state can be clearly monitored from the outside, and this has the effect of encouraging the driver and the passenger in the passenger seat to wear the seat belt.

A vehicle speed sensor for detecting the vehicle speed of the vehicle is connected to the control means. Based on the vehicle speed signal from the vehicle speed sensor, only when the vehicle speed of the vehicle is equal to or higher than a predetermined speed, the seat belt wearing display is provided. For example, when the vehicle is stopped, the wearing state of the seat belt is not displayed, but can be displayed only when the vehicle is substantially required to travel.

Further, the belt wearing detecting means includes a belt pull-out sensor provided in a retractor of a seat belt of a driver seat and a passenger seat, and a buckle engagement sensor provided in a buckle of a seat belt of a driver seat and a passenger seat. If the belt wearing detection is performed by both the belt pull-out sensor and the buckle locking sensor, the wearing of the seat belt can be more reliably detected.
