Helmet for sport activities comprising a lattice structure shaped so to accommodate a part of a user head and comprising empty and full portions arranged so that a continuous network of interconnected air channels runs through the lattice structure. The lattice structure comprises on its inner side at least one pocket permeable to air. The pocket is shaped so to accommodate said at least one permeable energy absorbing pad. Method for manufacturing the helmet comprising the steps of providing a lattice structure shaped so to receive a part of a user head and comprising at least one inner pocket, and inserting at least one energy absorbing pad which is permeable to air into said at least one pocket.

Protective clothing and/or equipment may comprise an impact mitigation layer which comprises a plurality of impact mitigation assemblies positioned between an exterior surface and an interior surface. The plurality of impact mitigation assemblies may comprise an impact absorbing array of impact mitigation structures having at least one filament and a lateral support wall or connecting element. When force is applied to the exterior surface, the structures of the impact absorbing materials deform in a desired and controlled manner, reducing the force received by the interior surface.

Disclosed is a safety helmet including an energy distribution part arranged in a body part of the safety helmet for distributing the energy of an impact in the safety helmet.

There is provided a helmet engageable with a human head portion. The helmet includes an inner shell, an outer shell and a shock absorbing layer. The shock absorbing layer is located between the inner shell and the outer shell, include at least one 3D structure and is defined by a plurality of interconnected 5 surfaces with a plurality of openings defined inbetween. A designing process is provided, including steps of providing a virtual inner shell model and outer shell model of the virtual helmet model, positioning virtual curves on the virtual inner shell/outer shell model, and generating virtual minimal surfaces. A manufacturing process is 10 further provided, including steps of conceiving the virtual helmet model using at least some steps of the designing process and additive manufacturing at least a portion of the helmet.

A combat helmet has a shell made from a ballistic rated material, the shell having an outer surface and an inner surface such that at least a portion of the outer surface is formed as a series of adjoining polygon shaped faceted regions that help distribute any force impacted on such regions across a relatively large portion of the shell. The faceted regions are curvedly contoured, and may extend through to the inner surface of the shell. The faceted regions may cover primarily the crown section of the helmet shell, the lower section, or both.

A helmet includes a helmet shell having an outer surface, an inner surface, and a plurality of slit openings. Each slit opening extends along a portion of the helmet shell. The slit openings include a pair of top slit openings that each extend longitudinally along a top portion of the helmet shell, where each top slit opening has a first length. The pair of top slit opening are spaced apart and define a flexible helmet portion spaced between the pair of top slit openings. The flexible helmet portion extends along the first length from a first end of the flexible helmet portion to a second end of the flexible helmet portion opposite to the first end, and the flexible helmet portion has a stiffness that varies along the first length from the first end to the second end.

A system and method for a protection helmet which has exterior moveable tiles to move upon impact and then retract to their original placements. The system prolongs the impact time by de-accelerating it and minimizing its damaging effects by spreading out the impact force over a larger surface area. A system and method for a helmet's face mask to absorb impact and return back to its original state whether impacted on its bars, interior/exterior assembly, or any part of the face mask. A system and method for a football helmet's padding to be multi-layered and have multiple ancillary cavities that compress and retract back to their original state.

Energy distribution structures provide architectural flexibility in various configurations, materials, and scalability, which enables a vast number of applications. An energy distribution structure or array thereof may include a three-dimensional outer component and a three-dimensional inner component within the outer component. The outer component absorbs and redirects initial energy from an applied energy event, and the inner component absorbs and redirects residual energy from the applied energy event. Such an applied energy event may be caused by a ballistic or non-ballistic impact, an instantaneous or prolonged impact such as atmospheric pressure or decompression, explosive overpressure (shockwave), low-velocity contact, and blunt force trauma. Energy distribution structures can increase the strength, resilience or survivability of such events, and reduce the injury or damage to target objects such as people, vehicles, structures, vessels and surfaces by shielding same from such events.

A bicycle helmet that fits over a surface of a head of a user generally includes at least one segment of flexible cell structures that form a radial honeycomb matrix movable between a folded condition where each side of the at least one segment is disposed generally parallel and an expanded condition where the radial honeycomb matrix of the at least one segment is configured to be expanded at least partially over the head of the user and arranged radially relative to the surface of the head of the user.

An impact attenuation helmet construction having a rigid outer shell, a rigid inner shell adapted to being worn upon a wearer's head and arranged a spatially separated distance from the outer shell. A plurality of resilient plasticized members, each having circular cross sectional profiles, are provided and extend between the inner and outer shells in a three dimensional array in order to spatially support said outer shell a distance from an outer surface of said inner shell. The resilient members include any of disk or sphere shaped components, each having outer and inner flattened mounting locations securing to opposing locations of the inner and outer shells.
