An energy absorption system is provided with a plurality of energy absorbing panels that may be releasably connected to a helmet. The energy absorbing panels are provided with a plurality of air flow channels defining a plurality of energy absorption chambers. Each of the air flow channels is designed to direct air flow from an anterior of the helmet to a posterior of the helmet when the energy absorbing panels are connected to an outer shell of the helmet.

A helmet for a head of a user with a liner with an outer shell and an energy management layer having an inner surface and a lower edge surrounding the inner surface at a helmet opening, at least two coupling points located on the inner surface proximal to the lower edge, at least one flexible forehead strap following the lower edge of the energy management layer and inwardly offset from the inner surface, at least two prongs comprising a stem and a head, the head having a larger cross-section than a cross-section of the stem, wherein the stem is attached to and projects away from the flexible forehead strap towards the inner surface and the head couples with the inner surface at one of the at least two coupling points, a continuous gap between the inner surface and the flexible forehead strap extending around an entirety of the lower edge.

Helmets and methods for manufacturing a helmet are described. An example helmet includes a shell and a shock absorbing liner attached to the shell. The shock absorbing liner includes a cavity. The helmet a shock absorbing insert formed of a material different than the material of the shock absorbing liner. The cavity is configured to retain the shock absorbing insert.

A ventilated helmet is provided. The helmet includes a shell defining a cavity, the shell having a front section provided with an opening to allow the wearer to see. The helmet also includes a transparent shield adapted having an inner surface and being adapted to substantially close the opening. Finally, the helmet includes a ventilation system having an evacuation subsystem adapted to create an evacuation airflow to evacuate humid air within the cavity to a surrounding environment. The ventilation system further has a pressurizing subsystem adapted to admit a pressurizing airflow within the cavity to create a high-pressure zone and a low-pressure zone within the cavity, wherein when in use, the wearer exhales air within the low-pressure zone, and wherein the high-pressure zone prevents air within the cavity from travelling from the low-pressure zone to the high-pressure zone. A method of evacuating humid air from the cavity is also provided.

A helmet for protecting the head of a user may include at least one liner comprising an inner surface and a lower edge surrounding the inner surface at a helmet opening configured to receive a head of a helmet wearer. At least two coupling points may be located on the inner surface proximal to the lower edge. At least one flexible forehead strap may follow the lower edge of the energy management layer and may be inwardly offset from the inner surface. At least two prongs may be coupled to, and slidably extend between, the flexible forehead strap and the at least two coupling points, respectively. A continuous gap between the inner surface and the flexible forehead strap may be provided by an offset created by the at least two prongs, the at least two prongs flexibly maintaining the offset.

Baseball caps to be worn on a person's head are provided. According to one embodiment, a baseball cap includes a dome configured to be placed on the wearer's head, wherein the dome includes one or more panels and one or more cooling channels. The baseball cap also includes a hub positioned at a top of the dome. The hub comprises a central cavity and one or more conduits in gaseous communication with the one or more cooling channels of the dome. A coolant output port is provided in gaseous communication with the central cavity of the hub. The coolant output port is configured to supply a coolant gas to the one or more cooling channels of the dome via the central cavity of the hub.

A bicycle helmet includes a body, a plurality of air inlets and a plurality of air outlets. The body includes a front portion, an upper portion, a rear portion and an inner portion. The upper portion includes a closed surface. A plurality of dimple structures are formed on the closed surface to produce an aerodynamic effect. The air inlets are formed on the front portion. The air outlets are formed on the rear portion. The inner portion includes a plurality of ribs, the ribs are positioned correspondingly to the air inlet and the air outlet and define air channels therein, an airflow flows through the body due to the airflow entering the body through the air inlets, passing through the air channels and exiting the body through the air outlets.

A chin-bar for a helmet with a crumple zone and an integrated air-flow system formed from passages running internally from the bottom to the top of the chin-bar. A scoop at the bottom of the chin-bar controls air flow. Diffusers at the top provide de-misting and fresh air to the rider.

A bicycle helmet for protecting the head of a wearer includes an outer shell and an energy dissipating inner layer coupled to the outer shell. The inner layer defines an inner surface, and front attachment locations are inwardly offset from the inner surface substantially at a frontal portion of the helmet. Rear attachment locations are inwardly offset from the inner surface substantially at a rear portion of the helmet. An internal ventilation system is supported by the front attachment locations and the rear attachment locations. The internal ventilation system is configured for direct engagement with the head of the wearer for supporting the helmet upon the head of the wearer. The internal ventilation system provides a gap between the head of the wearer and the inner surface. The gap allows ventilating air to flow over a substantial extent of the wearer's head and within the helmet.
