Helmet lined with bean bag beans better for your bean
A helmet which self-adapts to the shape of your skull.
The traditional inner foam padding got replaced by a selfadapting vacuum cushion, filled with expanded polypropylene balls in conjunction with a rigid shell.
By putting the helmet onto your head, you automatically press out the air and evacuate the cushion. The balls can’t move anymore, your helmet is moulded around your head.
Conventional Compressed foams react in a similar way to solid materials - they transfer energy in a straight line. Energy is passed on to the structure lying below point by point. The impact energy is reduced and spread over a wide area.
The Vaco 12 Effect Energy uses small polypropylene beads that each make contact with up to 12 other beads so that energy is not transferred in a linear way, but in all directions along random load inverters. The VACO 12 globes give away, causing energy to be undone by friction and deformation.

Hopefully we will see it in bike helmets soon. Self molding should seal all those pesky gaps around our odd shaped heads that make our helmets real noisy
Political correctness: a doctrine which holds forth the proposition that it is entirely possible to pick up a turd from the clean end.
