A headborne attachment platform includes multiple rigid plates and straps of connecting material connecting the rigid plates in an assembly at independently selectable and pre-set distances apart from each other. The assembly of rigid plates is shaped and connected to sit adjacent to, and surround, the bone regions of a wearer's skull, and define an overall headgear shape and contour. The straps are more flexible than the rigid plates in directions perpendicular to the thickness of the straps, and the straps are inelastic in a direction of a length thereof. A tightening mechanism is configured to adjust a circumference of a headband region, and the rigid plates have mounting features configured to mount an outer helmet shell and/or a headborne device. The rigid plates are sufficiently rigid to support and maintain their three-dimensional shape when subjected to forces exerted upon them by the outer helmet shell or headborne device.

Helmet comprising an outer shell having left and right side portions, inner padding configured to be located between the left and right side portions and a wearer's head, and a lateral adjustment device for adjusting the helmet's fit. The lateral adjustment device is between the outer shell and the inner padding and comprises a first leg with a distal end fixed to the outer shell or the inner padding; a second leg; a connecting leg portion interconnecting the first and second legs; a third leg with a distal end mounted to the second leg; and an actuator for moving the second leg between first and second positions with respect to the third leg while pivoting the connecting leg portion such that the first and second legs are movable from a first orientation to a second orientation. In the second orientation, the first and second legs lie in spaced planes.

In one embodiment, a protective helmet includes an outer shell made of a polyethylene material, wherein the shell is locally deformable when impacted with a strong force and an inner liner provided within the outer shell. A protective helmet comprising: an outer shell made of a polyethylene material, wherein the shell is locally deformable when impacted with a strong force; and an inner liner provided within the outer shell.

A helmet harness with a lace tightening system is disclosed. The helmet harness is configured to be secured to the inside of a helmet shell. The harness includes a lace tensioning system and lace guides for distributing forces arising from tension in the laces to provide a secure and comfortable and adjustable fit. An inner frame and an outer frame are connected by cam slides at their extremities to even out tension applied circumferentially and tension applied over wearer's head, and to absorb rotational forces applied to a helmet shell in which the harness is secured.

Aspects of the subject disclosure may include, for example, a protective shell having an exterior surface and an interior surface and a lever assembly positioned between the interior surface of the protective shell and a portion of a body. The lever assembly includes a lever having an elongated member extending between a first end and a second end and a pivot location. A fulcrum pivotally engages the pivot location of the lever, wherein the lever rotates about the fulcrum in response to an impact force applied along a first direction to the exterior surface of the protective shell. The lever assembly further includes a spring engaging the lever, wherein a rotation of the lever deforms the spring in a second direction to absorb a portion of a kinetic energy of the collision to redirect and reduce a transfer of a portion of force to the body. Other embodiments are disclosed.

An improved headband (12) for a head safety product such as a face shield, hardhat (10) or welding helmet includes a horizontal section (14) configured to encircle the head and an adjustment mechanism (14a) configured to adjust a circumference of the horizontal section. A nape-belt section (16) depends from the horizontal section (14) and is configured to cup the occipital area of the head and has a pivotal movement relative to the horizontal section (14). A flexible section (20) is connected between the horizontal section (14) and the nape-belt section (16). The flexible section (20) spring-biasing the pivotal movement of the nape-belt section (16) relative to the horizontal section (14).

A hardhat shell has a suspension that is secured to the shell by a hanger. The suspension has a horizontal band portion for extending around a user's head, and the suspension is positioned within a hardhat shell. At least one hanger is connected to the suspension for securing the suspension to the shell. Each hanger has a hook at a first end of the hanger, a latching surface located towards the middle of the hanger, and a lever arm at a second end of the hanger. At least one mount is formed on the inner surface of the shell. Each hanger is configured to securely engage a respective one of the mounts, with the latching surface of the respective hanger being in frictional engagement with the respective ledge surface of the mount. By manually pivoting the hanger, a user can cause the latching surface to disengage from the ledge surface.
