A garment worn by a wearer has an impact absorbing material comprising arrays of various hexagonal or other deformable polygonal-shaped structures positioned between an exterior surface and an interior surface. When force is applied to the exterior surface, the structures of the impact absorbing materials deform (e.g., buckle) in a desired manner, reducing the force received by the interior surface.

The present invention provides a head protection helmet comprising an impact resistant shell comprising: a cavity for accommodating a user's head and an array of crushable bodies having a hollow closed configuration, e.g. flutes in corrugated material 14,16, the crushable bodies each having an axis that extends outwardly from the cavity to absorb impact forces exerted along the direction of the axis.

Various embodiments of a spiral shaped element and embedded wavy materials are disclosed for use in a shock mitigating material to dissipate the energy associated with the impact of an object. The shock mitigating material can be used in helmets, bumpers, bullet proof vests, military armor, and other applications. One embodiment, among others, is a shock mitigating material having a plurality of spiral shaped elements, each having a circular cross section, and each being tapered from a large outside end to a small inside end but also having an embedded wavy material that can induce shear waves to mitigate the shock pressure and impulse.

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.

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.

The invention relates to a multi-step method with a number of processes and sub-processes that interact to allow for the selection, design and/or manufacture of a protective sports helmet for a specific player, or a recreational sports helmet for a specific person wearing the helmet. Once the desired protective sports helmet or recreational sports helmet is selected, information is collected from the individual player or wearer regarding the shape of his/her head and information about the impacts he/she has received while participating in the sport or activity. The collected information is processed to develop a bespoke energy attenuation assembly for use in the protective helmet. The energy attenuation assembly includes at least one energy attenuation member with a unique structural makeup and/or chemical composition. The energy attenuation assembly is purposely engineered to improve comfort and fit, as well as how the helmet responds when an impact or series of impacts are received by the helmet.

A bicycle helmet that fits over a surface of a head of a user generally includes a segment of flexible cell structures that form a radial honeycomb matrix movable between a folded condition where each side of the segment is disposed generally parallel and an expanded condition where the radial honeycomb matrix of the 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. The bicycle helmet includes a first and second side frame disposed respectively at the first and second ends of the honeycomb matrix.

The present disclosure discloses a helmet with a split type skeleton structure. The helmet includes a helmet body; the helmet body is composed of a head guard and a chin guard which are separated; the head guard and the chin guard are mounted through cooperation between a fastened spliced skeleton and a plug pin; the spliced skeleton is composed of two skeleton connection members arranged inside the head guard and a chin skeleton arranged inside the chin guard; and hollows of a surface of the chin skeleton are fixedly connected with a plurality of one-piece structured reinforcing ribs.

Articles including protective gear for a variety of sports and activities provide protection from one or both of linear and angular forces that either directly or indirectly impact the gear when it is donned. The articles include at least two layers of material that provide multimodal energy dissipation to minimize the extent of transmission of impact forces to tissue.
