I like that this one is different from existing organizers. It has the more stable design by keeping the hanging load centered instead of on the sides where it would tip over more easily when starting and stopping. As others have mentioned, the first one is too much like existing organizers and not worth our time making.
I think this would be awesome if you could make it generate electricity and store it in order to power/recharge your laptop or run a tv. This might motivate/require kids to get in some exercise, especially during the winter/rainy days they may be couped up inside.
I would think that the latches would be a safety issue in that they would concentrate instead of dissipate the force of a blow if it were to occur on their locations. That is assuming that they are as hard as or harder than the other materials in the helmet. If they were made of softer material, not something similar to a snowboard binding, it might not be an issue. I am hoping both helmets would have venting in the final stages.
