Abstract
Systems for indicating the status of a seatbelt buckle prior to a protective response are disclosed herein. An airbag activation system configured in accordance with one embodiment of the disclosure includes a normally closed magnetically operated reed switch. The reed switch is attached to a connector carried on one portion of a seatbelt, and a magnet is attached to a buckle carried on another portion of the seatbelt. Coupling the connector to the buckle causes the magnetic field of the magnet to move the reed switch from the normally closed position to an open position, thereby enabling the activation system to inflate the airbag in the event of an accident.
