A helmet can include a helmet body comprising an energy-absorbing layer and an outer shell disposed over the energy-absorbing layer. An electronic device can be integrated with the helmet body. A first electrical contact can be formed at an exterior of the outer shell and adapted to be in electrical communication with the electronic device. A helmet visor can be coupled to the helmet body with at least one visor arm, the helmet visor comprising controls integrated within the visor. A second electrical contact can be formed at an inner surface of the at least one visor arm and adapted to be in electrical communication with the controls integrated within the visor. The second electrical contact can be adapted to mateably couple with the first electrical contact such that the electronic device and the controls are adapted to be in electrical contact.

A safety helmet fan system includes a fan housing carrying a fan and configured to be mounted on an exterior of a safety helmet shell above a brim of the safety helmet shell, and an elongate cooling air duct connected to the fan housing to direct cooling air flow from the fan housing around the brim and into an interior of the safety helmet shell. The duct can have a flexible construction that allows the duct to be selectively reshaped to accommodate different safety helmet brim configurations. The duct can have a releasable connector configured to releasably connect the duct to a brim of a safety helmet shell.

A helmet is described herein. The helmet can be configured to hold the arms of a corresponding eyewear piece, such as an eyeglass or sunglass, through one or more features of the helmet. The helmet can further include an air deflector visor. The one or more features, such as one or more channels, allows for the helmet to receive and hold the eyewear of a wearer. Additionally, the helmet visor can utilize deflector vents to redirect airflow around the helmet for lower drag and/or deflect airflow to portions of the helmet to aid in the cooling of the wearer.

A skydiving helmet including a helmet shell having a front opening, is provided. The helmet further includes a visor having a lateral mounting section, where the visor is operable between a lowered position and a raised position. The skydiving helmet also includes a visor mounting system laterally positioned on the helmet shell to pivotally connect the lateral mounting section to the helmet shell. The visor mounting system includes a base plate having a cavity formed therein with a locking slot and a guiding section communicating with one another. The visor mounting system also includes a locking element positioned within the cavity and being operable between an extended configuration for preventing rotation of the visor, and a retracted configuration for allowing a frontward translation of the visor, away from the helmet front opening, and subsequent rotation of the visor, from the lowered to the raised position.

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 type variable helmet includes a half face unit formed to cover an upper part of a user's head, and an under face unit detachably attached to a lower part of the half face unit and configured to cover a lower part of the head of the user.

A helmet that can effectively reduce the rotational acceleration of an impact and at the same time also effectively reduce translational acceleration is provided. A helmet has an outer shell comprising a hard material and a shock absorbing liner (14) disposed inside the shell. The shock absorbing liner (14) comprises a main body liner (16), a recessed portion (30) provided at an inner surface of the main body liner (16), an insert liner (18) fitted into the recessed portion (30), and a central raised portion (42) (central support member) disposed between a bottom surface of the recessed portion (30) and a bottom surface of the insert liner (18). When the helmet receives an impact, the insert liner (18) swings about the central support member as a fulcrum, thereby reducing the impact.

A personal protection and ventilation system is provided. The system includes a gown having front and rear panels, a hood, and visor; a fan; an air tube; and a helmet. The fan is positioned between the wearer and a body-facing surface of the rear panel. The front panel and at least a portion of the hood are formed from a first material including a first spunbond layer, a spunbond-meltblown-spunbond laminate, and a liquid impervious elastic film disposed therebetween. The first material has an air volumetric flow rate of less than about 1 standard cubic feet per minute (scfm). The rear panel is formed from a second material including a nonwoven laminate having an air volumetric flow rate of about 20 scfm to about 80 scfm. Therefore, the fan is able to intake a sufficient amount of air from the environment through the rear panel to provide cooling/ventilation to the hood.
