A system for detecting proper usage of a seatbelt in a vehicle by an operator
of
the vehicle is provided. The seatbelt usage detection system includes a first communication
device arranged on the seatbelt and a second communication device. One of the first
and second communication devices is a transmitter and the other of the first and
second communication devices is a receiver. The receiver and transmitter are capable
of establishing a communication link with each other. The second communication
device is arranged in the vehicle so as to be able to establish a communication
link with the first communication device of a predetermined signal strength upon
proper fastening of the seatbelt around the body of an operator. The system also
includes a processing unit for monitoring the signal strength of the communication
link between the first and second communication devices and for providing a signal
that the seatbelt is unfastened when the signal strength is less than the predetermined
signal strength.
