Description

A method for generating occupant information in a car seat and a occupant safety monitoring system using the same

The present invention relates to a safety monitoring system, and more particularly, to a system for monitoring the safety of an occupant in a vehicle.

A car seat refers to a separate seat used by being fixedly installed on a car seat in a vehicle. Such a car seat is intended to protect an infant or child riding in a vehicle from impact. In general car seats, even when an infant or child is seated and the seat belt is fastened, it is difficult for the body to be fixed, so many guardians install and use a car seat in the car.

However, most infants and children complain of discomfort and stuffiness when they are seated in a car seat and wear a seat belt. In the end, in the absence of a guardian or taking advantage of the distraction of the guardian, loosen the fastened seat belt or escape from the car seat. Unlike general seats in vehicles, car seats do not have a device that can transmit information on whether or not the seat belt is fastened to the driver. There is a problem that is difficult to do.

In particular, in the case of a large vehicle carrying a large number of infants and children, in which it is difficult to manage and supervise each infant and child seated in a car seat and fasten a seat belt, such a problem may cause a major accident.
