Earlier this week we noted that helmet development continues as research has shown that rotational motion is something needs to be considered as well. Numerous helmets have tried to offer ways to provide additional support, and now we heard about Vacotechnology AG’s Vaco 12 technology, which used vacuum cushions that are comprised of small, round beads – the kind you might find in a stuffed animal or bean bag chair – and the concept here is to provide a snugger helmet that is comfortable and can help absorb impact up to four times more effectively than just a traditional foam helmet.
While it might not seem like brain surgery to come up with the idea of using small foam pellets, the idea hers is that each bead in fact has a limited number of contact points. This magic number is actually 12 (hence why the technology is called Vaco 12), where each bead can receive the kinetic energy and pass it on to its 12 contact points, which are further passed on and thus weaken according.
The helmets do utilize a solid shell on the outside, so it is more than just placing a bean bag on the head, but inside the head can receive a more snug fit as the beads conform to the various contours. The result is a natural fit without pressure points. About the only downside we see is that this could result in a rather warm head as the beads won’t exactly allow for ease of airflow – and the foam will likely insulate quite well. Not bad in some snow sports, but the rest of the time it could be hot.
Interestingly, the Vaco 12 helmet was originally designed for orthopedic rehabilitation use, but is now finding is way to sports – possibly helping prevent the very injuries in the very place.
