A safety helmet (10), including a rigid outer shell (11) and an inner part (11.1) made to absorb and deaden any impact endured by said helmet, and comprising an inner padding (14c) which provides a canalisation structure (16) for conducting air between said at least one air intake opening (12.1) and said at least one air extraction opening (13.1), characterized in that it comprises a cap (15), which, when the helmet is worn by said person, cooperates with said padding to provide a plurality of air channels at said canalizations of said padding and covers the head of the person at least at the padding itself.

An integrally formed safety helmet structure includes an assembly of a helmet shell or a shell body, a foam filling body enclosed in the shell body and a structure body. Geometrical array texture structures are disposed at the assembling interfaces between the shell body, the structure body and the foam filling body. In manufacturing, by means of a mold or molding module and solid foaming technique, the foam filling body is integrally formed to bond with the shell body and the structure body and the geometrical array texture structures so as to form a compact and rigid multilayer complex reinforcement structure. The complex reinforcement structure not only can enhance the structural strength of the entire safety helmet, but also has the advantages of material-saving, lightweight, high security and easy manufacturing.

A helmet includes a shell having an interior surface and a padding configured to provide progressive impact resistance. The padding includes a first padding layer and a second padding layer. The first padding layer has a first side configured to conform to the interior surface of the shell and an opposing second side that defines a plurality of first continuous extensions arranged in a spaced configuration defining a plurality of first recesses therebetween. The second padding layer has a third side configured to conform to a head of a wearer of the helmet and an opposing fourth side that defines a plurality of second continuous extensions arranged in a spaced configuration defining a plurality of second recesses therebetween.

A protective helmet, including a hard outer shell, a hard inner shell slidingly connected to, and spaced apart from, the outer shell, and a leaf spring including a center portion, a first end, and a second end, the leaf spring anchored only at the center portion onto the hard outer shell, the first end unattached to, and in sliding contact with the hard inner shell, and the second end unattached to, and in sliding contact with the hard inner shell. In a neutral position, the first end is spaced from the second end by a first distance, and when a force strikes the helmet, the first end is spaced from the second end by a second distance, the second distance being different from the first distance.

A composite geometry structure for the absorption and dissipation of the energy generated by an impact includes a plurality of hollow cells, adjacent and stably connected to each other. On each cell there are identified one or more arc elements which develop starting from two juxtaposed areas of the same perimeter edge of the cell, such arc elements being configured to be elastically deformed.

Helmets and methods for manufacturing a helmet are described. An example helmet includes a shell and a shock absorbing liner attached to the shell. The shock absorbing liner includes a cavity. The helmet a shock absorbing insert formed of a material different than the material of the shock absorbing liner. The cavity is configured to retain the shock absorbing insert.

An impact attenuation liner for a helmet includes an additively manufactured lattice structure configured to be disposed inside the helmet. The lattice structure includes a plurality of cells, each having a plurality of struts and nodes. The lattice structure also includes a top surface having a convex curvature corresponding to an inner surface of helmet and a bottom surface having a concave curvature configured to receive a user's head.

A shield system for protecting a curved object is described. The system comprises at least one flexible pad. The at least one flexible pad comprises a spacing ridge (7) projecting at an angle from a first major surface (3) of the pad for providing a spacing between the first major surface and a support ridge (9) projecting from the first major surface and extending transverse to the spacing ridge. The support ridge comprises a flexure region (11) adapted to unbend in the event that the pad is curved about an axis aligned with the spacing ridge to inhibit strain in the support ridge from causing deflection of the spacing ridge.

A body impact protection system includes an inner layer and an impact force dampening and defusing structure. The inner layer includes a material composition and is adjacent to a body part when the body impact protection system is worn. The impact force dampening and defusing structure is juxtaposed to the inner layer and includes a plurality of components. The components function to reduce pressure on the body part from an impact force on a layer by layer basis. Each layer of the system dampens and defuses the impact force such that, by the time it reaches the body part, it has been substantially attenuated and spread over a large area.
