Description
- This application claims the benefit of U.S. Provisional Application No. 61/084,443 entitled “Protective Headgear System” filed Jul. 29, 2008, which is incorporated by reference in its entirety.
- Protective headgear is required to be worn by workers in particular industries and/or in particular work environments. Typical protective headgear, referred to as a “hard hat”, includes a rigid outer shell having an internal cavity, and a suspension attached to the shell and positioned at least partially within the internal cavity. This protective headgear is designed to protect the wearer's head from injury when an impact is sustained on the headgear.
- A wide variety of protective headgear is currently available, and numerous modifications have been developed to improve the usefulness of the headgear for specific industries or environments. In one example, a flexible cover may be worn over the protective headgear. A flexible cover may be decorative, such as a cover that identifies the wearer or that communicates a message. A flexible cover may be functional, such as a cover that protects the wearer and/or the protective headgear from contaminants. Flexible covers typically include an elastic material along the edge of the cover, to secure the cover to the headgear. In a specific example, a nonwoven fabric cover for protective headgear is typically used in the nuclear power industry to protect both the wearer and the headgear from radioactive contamination. The nonwoven fabric cover can be easily cleaned and disposed of, together with protective clothing made from similar materials.
- A drawback to the use of a flexible cover on a protective headgear is that the headgear may become uncomfortable to the wearer. The elastic material at the edge of the cover can often migrate from the edges of the headgear to the head of the wearer.
FIG. 1 is a bottom view of a conventionalprotective headgear 100 that includes a rigidouter shell 110 having an internal cavity, asuspension 120 attached to the shell and positioned at least partially within the cavity, and aflexible cover 130. Thesuspension 120 provides a space for the wearer's head. Theflexible cover 130 includes anedge 132 and an elastic material along the edge. As illustrated inFIG. 1 , the elastic material of theflexible cover 130 can contract so that theedge 132 is in contact with the wearer's head. Theheadgear 100 can become quite uncomfortable to the wearer if the flexible cover provides significant retention of heat and/or moisture. - One method to decrease the discomfort of protective headgear equipped with a flexible cover includes securing the edge of the cover to the edge of the headgear. For example, mechanical clips or adhesive tapes may be used at various points to keep the edge of the cover from moving away from the edge of the headgear and toward the wearer's head. However, this is a cumbersome approach that also introduces other drawbacks. For example, if the reason for wearing the flexible cover is to localize radioactive contaminants on a disposable cover, then a mechanical clip used to secure the cover may become contaminated, making waste disposal much more complicated and expensive. In another example, adhesive tapes may only secure the cover temporarily. Failure of adhesive tape may distract the wearer from a hazardous environment, and will gradually make the headgear more uncomfortable.
- It would be desirable to provide a protective headgear that can retain the edges of a flexible cover worn on the headgear. Such a protective headgear ideally would provide the necessary protection to the worker's head, while also providing improved comfort relative to conventional covered headgear.
- In one aspect, the invention provides a protective headgear that includes a rigid outer shell including a bottom opening and an internal cavity, a suspension attached to the outer shell and positioned at least partially within the internal cavity, and a rim circumscribing at least a portion of the bottom opening and extending laterally from the outer shell.

FIG. 2 is a representation of a perspective view of aprotective headgear 200 that includes a rigidouter shell 210, asuspension 220, and arim 230. The rigidouter shell 210 includes a bottom opening 212 and aninternal cavity 214. Thesuspension 220 is attached to theouter shell 210 and is positioned at least partially within theinternal cavity 214. Therim 230 circumscribes at least a portion of the bottom opening 212, and extends laterally from theouter shell 210. Therim 230 includes anedge 232, and at least a portion of theedge 232 includes agroove 234. - The rigid
outer shell 210 may include any rigid material. Examples of rigid materials include rigid thermoplastic polymers, thermoset polymers, composite materials, and metals. Examples of rigid thermoplastic polymers include high-density polyethylene, high-impact polystyrene, acrylonitrile-butadiene-styrene copolymer, polyamides (including KEVLAR), polycarbonates, polyesters, polysulfones, poly(phenylene oxide), and mixtures of these. Examples of rigid thermoset polymers include epoxy thermosets, phenolic thermosets, amino thermosets, polyester thermosets, allyl thermosets, polyurethane thermosets, dicyanate thermosets, bismaleimide thermosets, acrylate thermosets, and mixtures of these. A composite material includes a thermoplastic and/or thermoset polymer combined with a filler material. Examples of filler materials include particulate fillers, fibrous fillers, and shaped preforms. Specific examples of composite materials include fiberglass composites, fabric composites and graphite composites. Specific examples of metals include steel, aluminum, titanium, and combinations of these with other metals. - The
suspension 220 includesflexible strips 222, aheadband 224, and anoptional adjustment mechanism 226. Preferably an internal dimension of the suspension can be adjusted. More preferably, the circumference of theheadband 224 can be adjusted. Examples of headgear suspensions are disclosed, for example, in U.S. Pat. Nos. 7,296,305; 7,174,575; 6,862,747; 6,609,254; 6,481,023; 6,317,895; and 5,950,245. - The
flexible strips 222 are attached to the rigidouter shell 210 and/or theheadband 224, and are configured to cross each other. Theflexible strips 222 thus can provide a crown portion of thesuspension 220. Preferably theends 223 of theflexible strips 222 are attached to theouter shell 210 at four or more points around the circumference of theinternal cavity 214, near thebottom opening 212. The lengths of the flexible strips may be fixed, or they may be adjustable so as to adjust an internal dimension of thesuspension 220. - The
headband 224 is attached to the rigidouter shell 210 and/or the flexible strips 222. Theheadband 224 and theflexible strips 222 together can provide a space for receiving a wearer's head. Preferably the circumference of theheadband 224 is adjustable, so that theprotective headgear 200 can be securely positioned on the wearer's head. Theheadband 224 may include anadjustable napestrap 225. Theheadband 224 may include theoptional adjustment mechanism 226, which allows the circumference of the headband to be adjusted by the wearer while theheadgear 200 is on the wearer's head. - The
rim 230 may include any rigid material, such as the materials listed above for the rigidouter shell 210. Therim 230 and theouter shell 210 may be the same material, or they may include different materials. Therim 230 may be integral with theouter shell 210, or it may be formed separately and then attached to theouter shell 210. Preferably therim 230 and theouter shell 230 are integral and are made of the same material. - In one example, the
rim 230 circumscribes the entire bottom opening 212, extending at least one inch from the bottom opening. In another example, therim 230 circumscribes the bottom opening only at the front of theheadgear 200. In another example, therim 230 circumscribes the entire bottom opening, such that the rim at the front of the headgear extends at least one inch from the bottom opening, and the rim at the sides and rear of the headgear extends less than 0.5 inch from the bottom opening. - The
rim 230 includes anedge 232, which includes agroove 234. Thegroove 234 may be present along theentire edge 232, or it may be present only at one or more portions of the edge. In one example, a portion of theedge 232 at the front of the headgear includes a front groove, and a portion of the edge at the rear of the headgear includes a rear groove. In another example, portions of theedge 232 at the sides of the headgear each include a side groove. In another example, a portion of theedge 232 at the front of the headgear includes a front groove, a portion of the edge at the rear of the headgear includes a rear groove, and portions of the edge at the sides of the headgear each include a side groove. - The
groove 234 may have a variety of dimensions. If the groove is present along the entire edge, then the width and depth may be uniform along the edge, or these dimensions may be different at different portions of the edge. If the groove is present only at one or more portions of the edge, then the individual grooves in the edge have lengths, widths and depths that may be the same or may be different from each other. - The
groove 234 may be integral with therim 230. Thegroove 234 instead may be present in a separate material attached to therim 230. Thus, the separate material may form at least a portion of theedge 232. A separate material that includes thegroove 234 may include a rigid material, such as the materials listed above for the rigidouter shell 210, or it may include a flexible material, such as an elastomer. - A rigid material that includes the
groove 234 may be attached to therim 230 by an adhesive. A rigid material that includes thegroove 234 may be attached to therim 230 mechanically. For example, a rigid material that includes thegroove 234 may have a shape that mates with the shape of theedge 232 to provide a compression fit between the material and the rim, thus extending theedge 232. In one specific example, the rigid material may have two concave portions on opposite sides of the material, where one of the concave portions mates with and extends theedge 232, and the other concave portion is thegroove 234. - A flexible material that includes the
groove 234 also may be attached to therim 230, either mechanically or by an adhesive. For example, an elastomeric material that includes thegroove 234 may be shaped as a closed loop. The closed loop may be extended to be positioned around therim 230, and then may be allowed to relax to provide a compression fit between the elastomeric material and therim 230. Preferably, a flexible material that includes thegroove 234 has enough stiffness that it can retain at least a portion of a flexible cover in thegroove 234. -
FIG. 3 is a representation of a partial cross-section view of aprotective headgear 300 that includes a rigidouter shell 310 and arim 330. Therim 330 includes anedge 332, at least a portion of which includes agroove 334, which may be the same asgroove 234 ofheadgear 200. Thegroove 334 has awidth 336 and adepth 338. Preferably the groove has awidth 336 of from 0.5 to 3 millimeters (mm). More preferably, the groove has awidth 336 of from 1 to 2.5 mm, and more preferably of from 1.5 to 2 mm. Preferably the groove has adepth 338 of from 1 to 5 mm. More preferably, the groove has adepth 338 of from 1.5 to 4 mm, and more preferably of from 2 to 3 mm. Preferably the groove has awidth 336 of from 1 to 2.5 mm, and adepth 338 of from 1.5 to 4 mm. More preferably the groove has awidth 336 of from 1.5 to 2 mm, and adepth 338 of from 2 to 3 mm. The preferred configuration and dimensions of the groove may depend on the properties of a flexible cover that is intended to be worn on the headgear. - Referring again to
FIG. 2 , the rigidouter shell 210 and therim 230 may have a variety of shapes, sizes and configurations. For example, the outer shell and/or the rim may include air vents to allow air to flow more readily to and from the wearer's head. The outer shell and/or the rim may include shaped segments for attaching accessories to the headgear. Examples of accessories include face shields, ear protectors, sun shields, visors, head lamps, flashlights, wireless communication devices, cushioning inserts, perspiration absorbers, eye protection retainers, and chin straps. - Preferably the
headgear 200 meets or exceeds the requirements of ANSI Z89.1-2003. Theheadgear 200 may electrically insulate the wearer, or it may provide little or no electrical insulation. The headgear may provide “Class G” protection, in which the headgear can insulate the wearer from 2,200 volts of electricity. The headgear may provide “Class E” protection, in which the headgear can insulate the wearer from 20,000 volts of electricity. The headgear may provide “Class C” protection, in which the headgear cannot insulate the wearer from 2,200 or more volts of electricity. -
FIG. 4 is a representation of a perspective view of aprotective headgear 400 that includes a rigidouter shell 410, asuspension 420, arim 430, and aflexible cover 440.

Therim 430 circumscribes at least a portion of thebottom opening 412, and extends laterally from theouter shell 410. Therim 430 includes anedge 432, and at least a portion of theedge 432 includes a groove (not shown). Theflexible cover 440 includes anedge 442, at least a portion of which is retained by the groove. - The
flexible cover 440 may be any flexible material. Examples of flexible materials include woven fabrics, nonwoven fabrics, flexible plastic sheets, mesh fabrics, and netting. In one example, theflexible cover 440 is a disposable cover for theprotective headgear 400, such as a cover to protect the headgear from dust. In another example, theflexible cover 440 is a decorative cover, such as a cover to identify the wearer as an individual or as part of a particular group of people, or a cover used to communicate a message. For example, the flexible cover could have a camouflage pattern, particularly if the protective headgear is a military helmet. Theflexible cover 440 may include an elastic material at least at a portion of theedge 442 of the cover. Preferably theflexible cover 440 includes an elastic material along theentire edge 442. - In one example, the
flexible cover 440 includes a nonwoven fabric that prevents contaminants from the surrounding environment from contacting the exterior of theprotective headgear 400. The nonwoven fabric may include poly(vinyl alcohol) (PVA). Nonwoven fabrics containing PVA can be designed to dissolve in hot water, and may also be broken down into carbon dioxide and water. An example of such a nonwoven fabric is OREX™ Certified Soluble T fabric, available from Eastern Technologies, Inc. (ETI, Ashford, Ala.). In this example, theflexible cover 440 includes an elastic material along theentire edge 442. An example of such a flexible cover is the OREX™ Hard Hat Cover (#CS1801), available from ETI. -
