ABSTRACT:
The circuit of this invention provides a safety belt system for both shoulder and seat belts which require the driver and any passengers to positively fasten the seat and shoulder harness in a sequential manner in order for the automobile to be started. After the engine is started, disconnection of any belt or harness causes a buzzer or like alarm to be actuated. The circuit is shown as being operable with either of two relay systems. One system uses a latching relay the other uses a stepping relay.
