History of the ,Modern, Motorcycle ,Helmet Helmets have been, around pretty much throughout human history. Examples of ,helmets,, presumably for military use, can be found in the pre-history of more than one culture. ,Helmets, came in a wide variety of shapes and sizes to serve a range of protective functions long before motorcycle ,helmets, were developed.
Battalion Chiefs ,helmets, were solid white with black numbers These ,helmets have, since ,been, discontinued in favor of a more ,modern, style using bright yellow, orange, and red, among other colors to denote rank, though the colored number panels persist. This particular setup ,has been, copied by a number of other California fire services.
Modern military helmet has it’s roots in WWI. Prior to that, since the time guns became common on the battlefield soldiers wore hats that sometimes looked like helmets, but had little protective value. The first steel helmets in WWI were issued by the French.
There ,has been, extraordinary improvements of ,helmets, from the old leather to the modernized-plastic football ,helmets, along with the face mask and energy- absorbent padding. In addition, the concern over preventing concussions, ,have, led to ,helmet, changes, impact testing methods and reconstruction of injuries during play helping to provide insight on concussions(4).
The materials of the ,helmet, must absorb what Miller calls the “deformation” of the ,helmet, when it is ,hit, by the ball – the dent it makes on impact – and settle back into place once the ball ,has, rebounded. “The 10mph gap sounds no big deal, but at those paces it adds a lot of force.”
