Custom manufactured headwear for a subject's head is provided. The headwear comprises an inner layer deposited by an additive manufacturing device. The headwear further comprises an outer layer deposited by the additive manufacturing device. The inner layer and the outer layer are each formed by the additive manufacture device utilizing a device data file derived from a subject data file. The subject data file is representative of the shape of the head and the device data file determining the shape of the headwear.

The present invention provides a protective circular band assembly for helmets. The assembly includes a front portion, two side portions and one back portion as a single structure, wherein the front portion and back portion are curved from a top surface to form a curve wherein the two side portions are configured adjust circumference of the assembly for different size helmets.

A plate for an article of footwear includes a substrate, a first strand portion attached to the substrate via first stitching, and a second strand portion disposed on the first layer. The first strand portion includes first segments that each extend between two different locations along the substrate to form a first layer on the substrate. The second strand portion includes second segments that each extend between two different locations along the substrate to form a second layer on the first layer.

The metallic crystal structures inspired edge-to-edge tessellations and a tessellation based lattice structures are disclosed. In accordance with an exemplary embodiment of the invention, basic unit lattice cells are stacked and connected to constitute a three-dimensional tessellations, wherein each of the basic unit lattice cells comprises a multiple flat connecting portions formed on a surface of the basic unit lattice cell and intersecting with a multiple of axes intersecting in a center of the basic unit lattice cell, and the flat connecting portions of one of the basic unit lattice cell is connected to the flat connecting portions of the adjacent basic unit lattice cell to constitute a connection structure of edge-to-edge tessellation. The formed tessellations are periodically tessellated in a design domain to form different tessellated lattice structures. The Functionally Tessellated (FT) lattice structures composed of different tessellations by interlocking into each other are also disclosed.

A modular helmet interface with a mounting cleat, threaded insert, and adhesive layer is provided. In one aspect, a mounting cleat is affixed to a helmet, such as a ballistic helmet, by an adhesive layer, the mounting cleat having an outer portion and a threaded insert within a cavity formed in the outer portion. The outer portion has an inward facing surface configured to receive an adhesive layer for coupling the inward facing surface to the helmet surface. In another aspect, a mounting cleat is secured to a helmet by way of a cleat-receiving securing member, the securing member affixed to the helmet by an adhesive layer. In a more limited aspect, a helmet having multiple mounting cleats configured to support an accessory mounting rail or a helmet mount assembly.

Systems and methods of a safety helmet for protecting the human head against repetitive impacts, moderate impacts and severe impacts so as to significantly reduce the likelihood of both translational and rotational brain injury and concussions can be provided. The helmet can include an outer shell, an omnidirectional liner disposed within and coupled to the outer shell and configured to move relative to the outer shell, and a chinstrap coupled to the omnidirectional liner. The chinstrap coupled to the omnidirectional liner can hold a wearer's head to the omnidirectional liner and prevent the chinstrap from applying forces to the wearer while omnidirectional liner moves relative to outer shell. Other embodiments may include a chinguard with a movable chincup.

A garment worn by a wearer has an exterior shell and an interior shell with various impact absorbing material between the exterior shell and the interior shell. The impact absorbing material includes multiple structures, such as rods or filaments, capable of deforming when force is applied then returning to its state prior to application of the force. In various embodiments, a rate sensitive material (RSM) is positioned in one or more locations relative to the exterior shell and the interior shell of the garment to further attenuate impacts to the garment. The RSM changes its resistance to force based on a rate at which the material is loaded.

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.

A helmet defining an opening for a user's head, the helmet including an outer shell providing a wave guide exit operatively associated with an integrated wave guide layer surrounded by the outer shell, the wave guide layer being adapted to direct sonic waves out the wave guide exit, thereby substantially preventing the sonic waves from penetrating through a remainder of the helmet to the opening. The wave guide layer may be a sonic wave transmission medium composed of acoustic metamaterial, wherein the wave guide layer communicates with the wave guide exit.

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.
