摘要
The present invention provides protective headgear comprising a shell (26) having an inwardly facing surface which in use faces the head (10) of a user of the headgear and an outwardly facing surface which in use faces away from the head (10) of a user. An outer layer (28) overlies at least a portion of the outwardly facing surface of the shell (26) and rupturing means (30) is provided for fixedly attaching the outer layer (28) to the remainder of the headgear at one or more locations. The rupturing means (30) is configured so as to fail when a force greater than a selected threshold is received on an outer surface (28) of the headgear which acts in an at least part tangential direction to rotate the headgear and the head (10) of the user. Upon failure of the rupturing means (30) at the one or more locations, the received force causes at least part of the outer layer (28) receiving the force to move relative to the shell (26) in a manner which is similar to the protective movement of the human scalp (18) relative to the skull (16). The present invention also relates to protective armour (100) and to a method of modifying protective headgear and protective armour.
