Abstract:
1. A helmet protector used in combination with a conventional helmet having a hard helmet outer layer adapted to be exposed to the atmosphere and configured to directly contact with another hard helmet outer layer of another helmet or another helmet protector when being worn by a user, the helmet protector comprising: a helmet protector cover, the helmet protector cover comprising a hard helmet protector layer, the helmet protector cover surrounding at least a portion of the helmet and defining an air space extending between the hard helmet protector cover layer and the hard helmet outer layer when the helmet protector is installed onto the helmet, the helmet protector cover having at least one opening providing an air passageway from the air space to the atmosphere located outside the helmet protector; and a plurality of spacers separating the helmet protector cover away from the helmet when the helmet protector is installed directly on the hard helmet outer layer of the conventional helmet, each of the plurality of spacers being separate discrete spacers spaced apart from each other and located at different positions on the helmet protector cover, and bridging the helmet and helmet protector cover through the air space when the helmet protector is installed on the helmet, wherein the air space surrounds the spacers and is unobstructed between the hard layer of the helmet protector cover and the hard helmet outer layer when the helmet protector is installed on the helmet to allow for propagation of waves generated by an impact to the hard outer layer of the helmet protector cover through the unobstructed air space to the hard helmet outer layer of the helmet, which reflects the waves back through the unobstructed air space and then exiting through the at least one passageway of the helmet protector to the outside atmosphere to dissipate energy from the impact to the helmet protector.
