4 Months of brainstorming, 3 major rebuilds, a little help from a mechanical engineer and BAM!
Here is the demo:YouTube - Ironman Helmet Hinge demo‏
Each side has a 3 piece hinge system, with 8 pivot points. I used a few low powered magnets on the faceplate and dome to ensure A nice seal when closed. The helmet is a default size Sharkhead.
