ABSTRACT:
An automatic conveying system of a car safety belt that controls various alarm functions and directions of a motor for releasing and fastening of the belt with an electronic controller constituted in such that a control unit scans switch states according to key inputs, and drives an alarm lamp, an alarm buzzer, an alarm chime, a solenoid and a driving motor. The control method provides the users of a car safety belt with convenience, and also solves problems of the prior relay-type control system such as high cost, largely occupied space and difficulty in checking when in trouble.
