Patent ID: 7173522

Claim:
A seatbelt reminder system for outputting a reminder for an occupant when the occupant leaves a seatbelt unfastened, comprising: a seat-belt fastening detecting element which detects a fastened state of said seatbelt; a running-state detecting element which detects a running state of a vehicle; and a reminder element which gives a reminder when an unfastened state of said seatbelt and said running state of said vehicle are detected from results of detection by said seat-belt fastening detecting element and said running-state detecting element, and makes a way of giving said reminder different between a case where said running state of said vehicle is detected while said unfastened state of said seatbelt is being detected and a case where said unfastened state of said seatbelt is detected while said running state of said vehicle is being detected, wherein said reminder element delays start of said reminder for a predetermined period of time from a time when the detected fastened state of said seatbelt changes from a fastened state to said unfastened state while said running state of said vehicle is being detected as compared with that in said case where said running state of said vehicle is detected while said unfastened state of said seatbelt is being detected.
