  • Indicator sensor for anti-whiplash system
    Patent number: 6333686
    Abstract: A system for alerting a vehicle occupant that an anti-whiplash system has been activated includes a wire disposed within an anti-whiplash system integrated into a vehicle seat. The wire is partially encased in a plastic plug which is easily inserted into a hole in the anti-whiplash system. At one end of the wire, a current generator is attached to provide a current therethrough. Also attached to the wire, at a location downstream of the anti-whiplash system, is a sensor that is configured to detect a change in the current flow through the wire. When the anti-whiplash system is activated, the moving parts shear the plastic plug and the wire contained inside, thus breaking the electrical circuit. The current sensor detects this change in current and then activates a warning signal indicator which provides notice to a vehicle occupant that the anti-whiplash system has been activated.
