Abstract

Bei einem Sturzhelm mit einer vorzugsweise annähernd kugelförmigen Kalotte (1) wird bei höheren Geschwindig­ keiten eine Verminderung der am Helm angreifenden Wind­ kräfte dadurch erreicht, daß die äußere Oberfläche der Kalotte (1) eine Verwirbelung der Luftströmung an der Oberfläche produzierende, nebeneinander angeordnete Unebenheiten (5, 5′, 5″) aufweist. For a helmet with a preferably approximately spherical cap (1) becomes faster at higher speeds a reduction in the wind attacking the helmet forces achieved in that the outer surface of the calotte (1) a swirl of air flow on the surface producing bumps arranged side by side (5, 5 ′, 5 ″).
