Abstract
A seatbelt monitoring system is provided for use onboard a vehicle having a seat assembly including at least one seat and corresponding seatbelt. The seatbelt monitoring system includes a wireless seatbelt status detector and a vehicle seatbelt status indicator. The wireless seatbelt status detector includes a seatbelt latch sensor, a first wireless transceiver, and a controller coupled to the seatbelt latch sensor and to the wireless sensor. The controller is configured to send a seatbelt latch signal via the first wireless transceiver when the seatbelt latch sensor indicates a change in seatbelt latch status. The vehicle seatbelt status indicator includes a second wireless transceiver and a processor coupled to the second wireless transceiver. The processor is configured to send a receipt signal to the wireless seatbelt status detector after receiving the seatbelt status signal via the second wireless transceiver.
