Layered materials and structures for enhanced impact absorption

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.

Rotation damping helmet
11464270 · 2022-10-11 ·

The present invention is a helmet system that reduces concussions by damping rotational force transmitted to a helmet user. The helmet has an exterior shell and an internal body that moves independently from the exterior shell. At least one magnetic source on the exterior shell's interior has a dipole directed axially at the internal body. At least one magnetic source on the internal body has a dipole aligned with the same axis, directed at the exterior shell. In a resting state magnetic sources generate a weak magnetic field. When an impact rotates the exterior shell, it moves off the initial alignment and closer to the internal body. The previously aligned magnetic sources torque. The magnetic source on the internal body torques in the opposite direction of the rotation, as do all initially aligned magnetic sources impacted. Angular momentum is displaced, diffused, offset, damping rotational force transmitted to a helmet user.

SPORT HELMET

A protective sport helmet includes an outer shell, and an inner padding mounted within the outer shell for at least partially covering the wearer's head, the inner padding defining a base face oriented toward the wearer's head and at least one pedestal extending from the base face away from the outer shell, the pedestal defining a pedestal face facing the wearer's head. At least one tangential shock absorber has a first face at least partially covering the pedestal face and a second face opposed the first face and configured for contacting the wearer's head. The tangential shock absorber includes a shearable member that is deformable such that the first face is movable relative to the second face in a direction having a radial component relative to an axis normal to the pedestal face.

The present technology relates to a helmet of a layered and segmented design including impact attenuation structures. The helmet can include a series of layers that individually, or in combination, provide the necessary functions of the helmet. The helmet may feature a layer with a low coefficient of friction to act as a slip layer and slide due to rotational force. The present technology includes impact attenuation structures of predetermined geometries, layers, and materials to allow for an appropriate impact response with a certain degree of control over the buckling process and an adaptive impact response. The present technology of impact attenuation structures may be applicable where impact absorption and controlled buckling is desired, such as bike helmets.

Protective helmet with integrated rotational limiter

A helmet is disclosed for protection during an impact. An inner liner may slidably couple to the outer liner through at least one return spring. The outer liner includes an interior surface with a shelf extending inward. The shelf includes an arresting surface. The inner liner has an exterior surface, an interior surface and an edge connecting the exterior surface to the interior surface. The edge faces the arresting surface of the shelf. The inner liner is slidably movable relative to the outer liner between a first position in which the edge of the inner liner is separated from the arresting surface of the shelf by a first gap, and an arrested position in which a portion of the edge of the inner liner is in contact with a portion of the arresting surface of the shelf.
