A helmet visor system may include a helmet shaped to accommodate a headset, a visor lens and a visor apparatus to pivotally move the visor lens between a stored position and a deployed position. The deployed position may be defined as a majority of the visor lens being extended from the helmet, and the stored position may be defined as the majority of the visor lens being occluded by the helmet within an interior of the helmet. The visor lens may be pivotally moveable between the stored position and the deployed position so as not to interfere with the headset.

The present disclosure relates to a rotating body fixing means for a helmet. The rotating body fixing means for a helmet, according to the present disclosure, is provided at the helmet comprising a helmet body (10) and a rotating body (20) rotatably coupled to the helmet body (10), and comprises a fixing part (100), which is slidably disposed at one side of the helmet body (10), slides such that the protruding degree thereof from the helmet body (10) varies, and comes in contact with the rotating body (20) when protruding from the helmet body (10).

A helmet for a rider of an on-road or off-road vehicle protects the rider's head. The helmet also may include various features for enhancing the riding experience.
