Head and Neck Restraint Myths

We've recently noticed the same question arise more and more regarding Head and Neck Restraint Systems: Can my [INSERT MANUFACTURER HERE] device be used in a car with 3-point belts, i.e a car using the manufacturer's shoulder/lap restraints?

Let's first define "USE". You can use any device in any car - the real question is whether or not it will do anything when the time comes!!

The current answer that we have is inconclusive. To this date, and to the best of myknowledge, there has been NO independent testing that attempts to test or rate ANY Head and Neck Restraint in a setting involving a 3-point belt.

I think that this question has been arising due to drivers wanting a head and neck restraint in any environment. There have also been speculation spreading throughout the web (and from a few manufacturers) that certain devices can be used with 3-point harnesses. Remember that SFI 38.1 testing of these devices uses a typical race-car set-up (5-6 point harnesses, racing seat, etc.). The question to ask is Has this device been tested to the same ratings when used with a 3-point seat-belt?
