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.

Abstract: Disclosed is a crash helmet with a substantially spherical cap part wherein a reduction of the forces acting on the helmet at high speeds is obtained by providing the surface of the cap with a plurality of topographical irregularities or surface unevennesses arranged adjacently to each other.

Abstract: An inner structure of a protective helmet secured to a helmet shell comprises a head bearing ring, a plurality of belt straps forming a spider and each having an end secured to the helmet shell and a plurality of fasteners each corresponding to the respective belt strap and formed of plastics. Each fastener has a shackle-shaped portion connected to the end of the respective belt strap. The head bearing ring is formed of plastics. Each fastener is connected to the head bearing ring by a hinge joint and formed integrally therewith such that the fastener is pivoted relative to the head bearing ring.
