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 method, equation, system, and device for electrically heating Indium Tin Oxide (ITO) and other transparent conductive materials having a uniform sheet resistivity for defogging and de-icing in a cold environment. The use of nonparallel busbars for connecting the conductive materials reduces excessive and dangerous hot zones. The mathematical analysis and equations provide a means of precisely providing an intermittent electrical connection so that the Watt density and heating is uniform, allowing much higher temperature for de-icing and defogging and more efficient use of energy. This same concept can be used for three dimensional formed heaters to compensate for non uniform sheet resistivity. Also shown are a means of improved busbar designs and an equation and a means of altering sheet resistivity to produce electric heaters with non parallel busbars of various shapes for uniform heating and Watt density.

A headgear device for a user including an integrated face shield, mask and hood. More specifically, the headgear device includes a hood, a face shield, and a moisture barrier fabric to cover the user's mouth when the headgear device is worn and direct air out through a breathable particle filtration fabric.

A helmet has a helmet shell. The helmet shell defines an inner space and a passage. The passage has an open end. The passage fluidly communicates with the inner space via the open end. The helmet further comprises an electrical heating device. The electrical heating device is disposed within the helmet shell for heating the passage.

The present invention provides a laminated substrate for use as an anti-fogging insert for an eye shield, more particularly for use as a heated anti-fogging insert for a visor or goggles.

There is provided a visor assembly (1), preferably for the motorcycle helment, comprising a shield-visor (2) having a surface, an overlay-visor (6) adapted to be releasably attached to the shield-visor, the overlay-visor comprising a viewing area, an integrally formed spacer (7) extending along at least a portion of a periphery of the viewing area, and a gasket (8) upon a distal surface of the spacer; and a mechanical fastening (11) releasably attaching the overlay-visor to the surface of the shield-visor.

A helmet including a visor assembly having a breath guard is provided. The visor assembly includes a visor pivotally connected to the helmet shell and having an inner surface facing the cavity when in the lowered position. The visor assembly further includes a breath guard interface provided below the visor and a breath guard which has a visor interface connected to the breath guard interface of the visor assembly. The breath guard includes a flexible member connected to and extending from the visor interface and a contact surface shaped and configured to engage the wearer's face around the nose and mouth for deflecting humid air away from the inner surface of the visor. The flexible member has a channel extending along the visor interface having a substantially V-shaped cross-section configured to allow the flexible member to be deformed when raising the visor.
