"Adjustment and release mechanism(s) shall be accessible to both the user and to external personnel such that no additional motion is required, other than the release of the seat belts, to disengage the Head and Neck Restraint System during emergency situations."

I've said it before. I think the Isaac fits this requirement. To disengage the Isaac head and neck restraint system during emergency situations, no additional motion is required other than the release of the seat belts. The spec doesn't differentiate between "releasing the belts from the head and neck restraint system" and "releasing the seat belts from the driver".
And we don't even have to address the notion that a worker cutting the belts with a knife constitutes a "release of the seat belts" and of their attendant head and neck restraint system.
