Abstract
The invention relates to a military safety helmet with a cap resistant to bombardment and an internal band arrangement, connected firmly to the helmet cap at several points and comprised of an approximately horizontally encircling annular supporting band, a plurality of bands extending in a radiating manner from a central fastening piece on the top side of the helmet and bands for connecting the adjacent radiating bands. The internal band arrangement provides all-round impact damping, especially under the effect of shocks, and good ventilation since the bands have formed-on bosses pointing towards the inner face of the helmet cap.
Above the supporting band, fastening strips extends which have no bosses and the ends of which are connected firmly to the helmet cap in such a way that the band arrangement rests against the inner face of the helmet cap via the bosses. The radiating bands are approximately the width of the bosses, and the bosses are preferably designed as hollow cylinders.
