Technical Field

The invention relates to the technical field of traffic, in particular to a multipoint induction safety belt unfastening reminding system.

Background

The conventional safety belt unfastening reminding system can detect whether a driver seat or a passenger seat wears a safety belt or not, and if the driver seat or the passenger seat does not wear the safety belt, the vehicle can give an alarm. However, most of the vehicle safety belts are not fastened and only stay at the level of meeting the regulations, and the strong requirement that the passengers fasten the safety belts is not really achieved. The correct use of the vehicle safety belt plays a great role in saving the lives of passengers in the event of an accident.

It has been found through extensive search that some typical prior art, such as patent CN1264709C, provides a belting reminder which enables a screen to display warning contents intended that a seat belt should be fastened when the ignition switch is turned on and the belting detection means detects that the seat belt is not fastened. Or as in patent CN109927603A, which focuses on having a seat back and a seat base, and a biosensor, in combination with biotechnology to detect physiological characteristics of a seat occupant. As another example, CN105946787A, a typical case discloses a vehicle seat belt reminder, which can remind passengers and drivers to wear seat belts in time, and when the passengers do not wear seat belts within a set time after receiving the reminder, send local information to a remote control center.
