Abstract
A cap arrangement is disclosed for sealing the space between the outer surface of a protective helmet and the upper edge of a pivotally mounted visor carried by the helmet, to prevent, for example, sawdust passing to the space on the inside of the visor during timber sawing operations. The cap arrangement comprises a sheet of fabric having a front edge secured to the upper edge of the visor and a rear edge secured to an elastic ribbon attached at its ends to the mountings which pivotally support the visor at the sides of the helmet.
