Patent ID: 8615817

Claim:
Protective headgear comprising: a shell having an inwardly facing surface which in use faces the head of a user of the headgear and an outwardly facing surface which in use faces away from the head of a user; an outer layer which overlies at least a portion of the outwardly facing surface of the shell; and rupturing means for fixedly attaching the outer layer to a remainder of the headgear at one or more locations, wherein: the rupturing means is configured so as to fail when a force greater than a selected threshold is received on an outer surface of the headgear which acts in an at least part tangential direction to rotate the headgear and the head of the user, and upon failure of the rupturing means at the one or more locations, the received force causes at least part of the outer layer receiving the force to move relative to the shell in a manner which is similar to the protective movement of the human scalp relative to the skull.
