20120036619 | Helmet - The present invention concerns a helmet with reduced weight but improves energy absorbing possibilities and protection against penetration comprising at least a rigi outer shell and an inner portion of energy absorbing material. At least a portion of the rigid outer shell is thin and has a thickness of 0.01-4 mm, preferably 0.1-1.0 mm in order to collapse at a crash and thus absorb energy and that a coated net, coated woven or coated nonwoven material is at least partially provided between the rigid outer shell and the inner portion of energy absorbing material in order to at least compensate for the penetration protection loss due to the thin rigid outer shell. | 02-16-2012 |
