<p>A visor (4) is mounted on a mounting base plate (7) on a shell (2) of a helmet for rotation or pivotal movement between fully opened and closed positions. the mounting base plate (7) and the visor (4) are provided with two bayonet mechanisms (B1, B2) having their disconnecting positions at different pivoted positions of the visor (4). The visor (4) can be rotatably and reliably mounted on the shell (2) by sequentially bringing the bayonet mechanisms (B1, B2) into the state of connection. <IMAGE></p> |
