摘要
The crash helmet is provided with a swivel-mounted visor attached along its upper edge to a hopped bracket for swivel movement. When raising the visor into its opened position the visor first swivels with the bracket about the points of articulation on the helmet and then swivels again relative to the bracket. Thus, in the open position, the lower edge of the visor adjoins the front edge of the view space of the helmet so that there are no air pockets to cause dangerous wind resistance.
