Patent attributes
A helmet which is to be worn on a head of a wearer. The helmet includes a shell adapted to surround a wearer's head with the inner surface of the shell being spaced from the wearer's head at an initial pre-impact relative position. A subliner in contact with the wearer's head when the helmet is worn prior to an impact and during an impact, includes at least one viscoelastic foam subliner element extending from the inner surface of the shell. The subliner element is radially partitioned into individual and independent panel-shaped segments nested with respect to each other and have major side surfaces. Some of the nested segments have double-sided nano tape positioned between the major side surfaces thereof in direct contacting engagement with the nano tape and at least some of the major side surfaces of the remaining nested segments are in direct facing relation without nano tape therebetween.
