Abstract
A safety helmet includes an outer shell configured for surrounding a head of a user, and an infrared reflective layer disposed in an interior of the outer shell. The infrared reflective layer is configured for reflecting at a least a portion of incident infrared radiation transmitted through the outer shell. The infrared reflective layer has infrared reflectivity of at least 40%. The safety helmet further may have an evaporative cooling pad positioned within a cavity defined by the inner surface of the outer shell. A method of manufacturing a safety helmet is also disclosed.
Claims18
A safety helmet comprising:
- an outer shell configured for surrounding a head of a user comprising one or more vent openings;
- an infrared reflective layer disposed in an interior of the outer shell comprising one or more cutouts corresponding to the one or more vent openings, the infrared reflective layer being configured for reflecting at a least a portion of incident infrared radiation transmitted through the outer shell;
- and
- an evaporative cooling pad positioned within the interior of the outer shell and aligned with the one or more vent openings, the evaporative cooling pad comprising:
- a top waterproof, vapor permeable layer and a bottom waterproof, vapor permeable layer with a cavity defined therebetween, wherein an outside surface of the bottom waterproof, vapor permeable layer is configured to be in contact with the head of the user;
- and
- a liquid absorbing layer positioned within the cavity.
