<p>The safety helmet with visor is for a motorcyclist or skier. It has a transverse deflector (4) fixed on a mounting in front of the user's forehead. This has a concave curve so that the air hitting the front of it is deflected downwards and forms a pneumatic screen in front of the user's eyes. The deflector delimits a passage which, in section, has a concave curve. This is open towards the front but closed laterally. The deflector can be a short visor with a slot level with the user's eyes.</p> |
