Abstract: Existing devices for stabilizing a safety helmet such as a hard hat are either unduly complicated or ill adapted as retrofits for existing helmets. A simple restraining device for use on new or existing helmets includes a bracket located at the center of the interior of each side of the helmet for pivotally supporting front and rear headbands. Pins extending through the headbands into arcuate slots in the brackets limit rotation of the front and rear headbands with respect to the brackets. A force tending to lift or rotate the helmet from the wearer's head will cause the headbands to pivot downwardly and inwardly against the wearer's head, thus inhibiting removal thereof from the head of the wearer.

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 extend 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: A suspension element for suspending a load and absorbing energy if the load is increased suddenly above a predetermined minimum includes a normally rigid ring that is permanently deformable under an applied load above said minimum. Diametrically opposite areas of the ring are connected to a support and a load, but the opposite sides of the ring between those areas are free of the connecting means and subject to being pulled toward each other if the load suspended by the ring suddenly increases beyond the predetermined miminum and elongates the ring in the direction of the movement of the load. The energy required to thus deform the ring is absorbed by the ring.

Abstract: A safety cap has an energy absorbing suspension including crown straps for supporting engagement with the crown of a wearer's head connected to elastically deformable, rupturable and controlled plastically deformable portions of connecting means attached to anchor means in the shell of the cap. The connecting means have end portions adapted to be attached to and wedgingly engage the anchor means. The shock or impact of a blow against the shell suspended on the resisting wearer's head is partially absorbed initially by a wedging action which continues until the end portions are fully seated relative to the anchor means. Further, loading causes the crown straps to pull against, deform and bend energy absorbing portions of the connecting means into adjoining apertures of predetermined size and shape. Finally, at a predetermined force, the bending moments at opposite ends of the energy absorbing portions exceed the tensile yield strength of the material and causes the portions to rupture.

Abstract: A hard hat suspension which includes a group of highly curved, narrow and transversely thick suspension legs and a second group of slightly curved, wide and transversely thin suspension legs in angularly spaced relation, arranged so that the more yieldable highly curved suspension legs are initially distended and come into operation upon the application of external force to the hat shell, as by impact from a falling object, before the less yieldable, slightly curved suspension legs come into operation. While the instant suspension is of normally elastic plastic material, which materials become brittle at low temperatures, the highly curved suspension legs are capable of straightening or "uncoiling" even when brittle without breaking to absorb energy and spread load between the highly curved legs without effective operation of the slightly curved legs.
