A detachable pad fastening structure of a helmet includes a first fastening unit, which includes a first fastening member having a fastening hole formed therein and is disposed at an inner surface of a helmet main body. A second fastening unit includes a through-hole in the form of a slot in a detachable pad and a second fastening member formed to be movable relative to the through-hole, having at least a part protruding toward the outside of the detachable pad so as to be inserted into the fastening hole when the second fastening member is located at one side of the through-hole, and configured to be inserted toward the inside of the detachable pad so as to be removed from the fastening hole when the second fastening member is moved relative to the through-hole toward the other side of the through-hole.

The present invention is directed to a protective sports helmet including a crown energy attenuation assembly positioned within a crown region of the helmet shell. The crown energy attenuation assembly includes: a first energy attenuation element with a plurality of sidewalls arranged to form a hexagonal housing, wherein a first sidewall has a substantially planar configuration; a second energy attenuation element with a plurality of sidewalls arranged to form a hexagonal housing, wherein a first sidewall has a substantially planar configuration; and, a third energy attenuation element with a plurality of sidewalls that are arranged to form a hexagonal housing. A first crown gap is formed between the first and second energy attenuation elements. A second crown gap is formed between the second and third energy attenuation elements. A third crown gap is formed between an extent of the third and first energy attenuation elements. The crown energy attenuation assembly further includes a layer positioned adjacent to the plurality of sidewalls of the energy attenuation elements.

A helmet sizing assembly for adjusting the size of a helmet includes a plurality of helmet liners that each has a dome shape to conform to an inside of a helmet. The plurality of helmet liners has a sequentially increasing size ranging between a minimum size and a maximum size. In this way a selected number of the plurality of helmet liners can be stacked inside each other to accommodate a variety of head sizes. Each of the helmet liners is comprised of a resiliently compressible material to facilitate the user's head to be protected from impact energy when the user wears the helmet.

A sports helmet kit has a shell, attachable face guard, composite helmet liner, and fit pods to improve and customize the fit of the helmet to the wearer. The composite liner consists of a base liner and a selected group of fit elements, for example, fit pods, removably attached to the inner surface of the base liner (i.e., the surface of the base liner facing the wearer's head). The fit pods are selected from a set of fit pods having different properties, for example, different sizes, thicknesses, densities, and cross-sections. The selection of fit pods from the set may be aided by taking anatomical measurements of the wearer's head and analyzing the measurements with respect to the geometry of the helmet to produce a pressure map. The measurements may be taken by physical contact or by non-contact means. The fit pods may be selected to optimize a pressure map, and thus optimize the fit, for a given wearer of the helmet.

A protective helmet with first and second helmet sections each including an outer shell section and an inner layer section of protective material. The first and second helmet sections are displaceable relative to one another to adjust a size of the helmet. Two opposed side protective members are received inwardly of the outer shell sections on opposed sides of the helmet. Means for adjusting a position of the side protective members relative to the inner layer sections of protective material are provided. The means are configured such that, when the protective helmet is adjusted when on the head of the wearer, the protective members remain substantially stationary with respect to the head of the wearer when the inner layer sections are displaced with the first and second helmet sections.

A modular helmet system with a removable/detachable/interchangeable exterior shell, an inner force-absorbing layer releasably connected to the rigid exterior shell layer, and a multiple fastening devices associated with the shell which allow the shell to be interchanged/replaced/reconfigured at will. The shell as a single piece unit, or combinable components bear the fastening devices designed to enable rapid, secure interchange of the helmet system's layers, therefore allowing the helmet to be adapted for climatic, functional, and aesthetic preferences.

A headband with one or more protective inserts. The inserts may be strategically positioned to provide protection for specific areas of a person's head that are most vulnerable to impact, depending on the sport or other activity. The inserts may be directly attached to the headband, or may be enclosed in pouches which are directly attached to the headband. The headband may be worn with or without additional headgear, and may be configured to cooperate with the additional headgear as to form, fit, and functionality.

Helmet padding systems are disclosed. One helmet padding system includes a rigid shell configured to cover a top of a user's head and be worn under a piece of headgear. The rigid shell includes a first pair of slots configured to extend in a direction from a back of the user's head toward a front of the user's head when the rigid shell is worn on the user's head. The first pair of slots define a central portion and opposed side portions of the rigid shell. The central portion includes at least one flap extending from the central portion across one of the first pair of slots and covering a first region of one of the opposed side portions of the rigid shell. A spacing pad is positioned within the rigid shell.

The present disclosure relates to a dual helmet that can be easily converted into two sets of helmets having protective cushioning, and which are comfortable, yet strong, safe, and up to the required standards The helmet includes a first shell and a second shell defining a shell of a first helmet and a second helmet, respectively. The second shell is removably disposed over the first shell such that the helmet can be used as a single combine helmet when the shells are together, and further, the second shell can be separated from the first shell to form two separate helmets. The helmet includes a first cushion disposed within the first shell, and a second cushion for the second helmet being removably configured within the first cushion such that the second cushion can be separated by slightly ending it, and later can be configured with the second shell to form the second helmet and the first helmet, as required.

A helmet pad includes a substrate having first side attachable to an interior surface of a helmet. The helmet pad includes an outer lattice layer peripherally attached to a second side of the substrate. The second side is opposite to the first side. In one embodiment, the outer lattice layer includes fibers attached in one of: (i) a Voronoi lattice unit cells; and (ii) tetrahedral lattice unit cells. The helmet pad includes padding material received in an enclosure between the second surface of the substrate and the outer lattice layer.
