I have the Safety Solutions D Cell Harness. I chose it because it is independent of the shoulder harness (HANS) or the lap belt (Hutchens) devices. Failure of any of the car mounted restraint belts render the Hans and Hutchens ineffective. Do any of these devices truly perform as claimed? Any crash test engineers out there?
Now, I do believe that all these devices work to somewhat limit head and neck movement...the theory seems sound. Does anyone have any testing data comparing the different systems?
I have seen the HANS device in action on the Hans website (straight forward deceleration), but how does the Hans (and other devices) perform in protecting the user when the deceleration is from the side, or in a spin, or a roll (barrel or endo) before impact?
Food for thought,
