Seat belt failure warning apparatus

A seat belt failure warning apparatus comprising:

• a wearing state detection section that detects wearing or non-wearing of a webbing of a seat belt device;
• a drawing-out amount detection section that detects a drawing-out amount of the webbing;
• a failure determination unit that determines whether the seat belt device has had a failure or not;
• a display section that switchingly displays a variety of information including failure information of the seat belt device which indicates that the seat belt device has had a failure as a determination result by the failure determination unit;
• and
• a control unit that controls display of the display section,
• wherein when the wearing state detection section detects non-wearing of the webbing and the drawing-out amount detection section detects drawing-out of the webbing after the failure determination unit determines the seat belt device has had a failure, the control unit causes the display section to display failure information of the seat belt device regardless of a display priority of information.
