A NOCSAE-certified football helmet having a plastic shell, internal padding attached to an inner surface of the shell, and a face guard attached to the shell, is configured and designed to have a Predictive Concussion Incidence below 1.90, or 0.75 plus or minus 0.25, or in the range of 0.50 to 1.90, as measured by the 2018 Adult Football STAR Methodology. The face guard is attached to the shell at a plurality of attachment points below a line constructed through the midpoint of the height of the helmet and has an upper portion which contacts the shell above the face opening, without being attached to the shell at that point. The internal padding includes a front pad attached within the shell above the face opening, defining a first zone of a first stiffness and, adjacent to and above the first zone, a second zone of a second stiffness lower than the first stiffness. The internal padding also includes helmet liners which are not inflatable, and which contain Poron pads.

A system for protecting a head of a wearer from an impact force includes a helmet defining an interior space for housing the head and at least one damper coupled to the helmet at a first end and extending therefrom along a longitudinal axis to a second end. The damper includes of a plurality compressible energy damper elements concentrically arranged about the longitudinal axis. The plurality of compressible energy damper elements includes an outer damper element and an inner damper element. The outer damper element surrounds the inner damper element and extends to the second end of the damper. The outer damper element has a first uncompressed length and the inner element has a second uncompressed length that is different from the first uncompressed length. Alternatively, the plurality of compressible damper elements are concentrically arranged and are arranged end to end in series.

A helmet including a body, an outer shell having an inner surface and an outer surface and a plurality of shock absorbers, the shock absorbers being positioned internal of the outer shell. A first set of shock absorbers has a first shock absorption characteristic and a second set of shock absorbers has a second shock absorption characteristic, the second shock absorption characteristic being different than the first shock absorption characteristic.

A device (e.g., an article of athletic gear) comprising a cushioning component for absorbing energy when the device is contacted (i.e., impacted or otherwise contacted), in which the cushioning component comprises a core comprising a plurality of zones of different materials (e.g., which may differ in one or more materials properties such as density, stiffness, resilience, etc.) and a covering disposed on the core. In some embodiments, a given one of the zones of different materials may be a zone of expanded microspheres. The cushioning component may provide enhanced protection, comfort, and/or vibration or other shock absorption while being relatively lightweight.

A helmet may be worn on a head of a wearer having a shape and a contour. The helmet may have a plurality of layers coupled together including an energy management layer and an outer shell layer disposed over the energy management layer. The plurality of layers are integrally formed with one another, and the energy management layer is configured to absorb and dissipate energy received by the helmet during an impact by an external force. The outer shell layer is configured to disperse and dissipate impact energy from the external force. Each of the plurality of layers has a density and a geometry, and the density or geometry of at least one layer differs from the density or geometry of at least another layer.

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 football helmet is provided having a one-piece molded shell with an impact attenuation system. This system includes an impact attenuation member formed in an extent of the front shell portion by removing material from the front portion. The impact attenuation member is purposely engineered to change how the front portion responds to an impact force applied substantially normal to the front portion as compared to how other portions of the shell respond to that impact force. In one version, the impact attenuation member is a cantilevered segment formed in the front portion of the shell.

The present invention provides a protective headgear having a multi-layered shell to attenuate amplitude of incident mechanical waves of a blunt trauma to a human head by inducing destructive interference with the incident mechanical waves through phase reversal of reflected mechanical waves reflecting off a boundary between two adjacent layers of the protective headgear, and by coaxially converging the phase-reversed reflected mechanical waves with the incident mechanical waves. The multi-layered shell is configured to equally protect people having a similar size of head but with a range of body weight.

A shock reducing helmet includes a helmet body made of an outer and inner shell, ear openings, and face shield or visor that connects flush to the helmet body.

The outer shell is formed from the strongest and lightest weight materials, such as polycarbonate, or other plastics, Kevlar, carbon fiber, or metal, to provide a high strength to weight ratio and minimize fracture.

The inner chamber includes shock absorbing structures made from materials such as a nickel-titanium shape-memory alloy, polycarbonate, other plastics, Kevlar, carbon fiber, or metal. Some variants have a viscous or gaseous layer around the springs to increase stability upon linear and rotational impact.

The face shield or visor is made of a clear polycarbonate that connects flush with the outer shell to eliminate visibility interference and rotational injuries caused by competitors pulling the metal bars commonly present in football helmets.

A football helmet is disclosed that includes a shell constructed of fiber reinforced epoxy resin, a liner made from expanded polypropylene, an impact absorbing layer situated between the liner and the shell, and a face guard. The impact absorbing layer is constructed from either expanded polypropylene or a viscoelastic polymer encased in a suitable thin yet resilient and elastic membrane. An optional impact absorbing band is also shown disposed around the inner periphery of the liner and encircling the player's head. The impact absorbing band serves to reduce impact forces occurring from side helmet impact with objects or players.
