Detailed Description
Referring generally to the drawings, various embodiments of a safety helmet are shown that includes a shell material designed to provide improved protection from potential safety hazards (e.g., falling objects). In general, applicants have determined that by constructing the outer shell from one or more of the innovative materials discussed herein, the helmet can exhibit improved characteristics (as discussed and quantified below) over a wide range of temperatures and impact speeds present in a construction environment, thereby providing protection under more extreme environmental conditions. Thus, applicants have identified various innovative materials discussed herein that provide unique and innovative combinations of material properties, and have identified that these materials have significant performance improvements when used in helmet/headpiece applications. Further, in typical headgear designs, the desired structural properties are provided by having a relatively thicker, larger, and/or heavier safety shell. In some embodiments, applicants have devised a helmet shell that employs the innovative materials discussed herein to provide improved structural performance, thereby allowing for the design of a helmet shell with a smaller wall thickness and/or a lighter weight. This design improvement allows the helmet to provide a high level of protection while achieving a higher user comfort, which is particularly important in the case of protective work helmets/helmets, as the user may wear the device for many hours during the work day/shift.
Referring to fig. 1, an exploded view of a headgear 10 according to an exemplary embodiment is shown. The helmet 10 includes an outer shell 12 formed of a rigid material, such as a rigid polymeric material. The outer shell 12 includes a crown portion 13 and a bottom portion or brim portion 15 defining a lower circumference of the helmet 10 extending along an exterior surface of the outer shell 12. The crown portion is positioned in a central region of the helmet about a central point. The housing 12 further includes an interior surface. In one embodiment, the helmet 10 includes a ballistic blanket 14 supported within the outer shell 12 and specifically positioned within an interior surface that defines a cavity sized to receive the head of a wearer or operator. Details of various embodiments of the housing 12 are discussed in more detail below. The headgear 10 includes a suspension system 16 and chin strap 18 for supporting the headgear 10 and securing the headgear to the user's head. The helmet 10 also includes various padding layers 20 for providing increased comfort to the wearer.
Referring to fig. 2-8, various material characteristics of the innovative materials forming the housing 12 are shown (see, e.g., fig. 1). These characteristics are shown in comparison to the selection of conventional safety cap materials. Applicants have determined that designing a helmet shell with an innovative material having one or more of the characteristics discussed herein allows the designed innovative helmet to have the performance improvements discussed herein, including structural performance improvements and/or volume/weight/thickness reductions. In particular embodiments, applicants have determined that the mevalonate material (Milwaukee Material) has one or more of the characteristics discussed herein with respect to fig. 2-3.
As noted above, applicants have determined that improved headgear shells can be achieved using the materials discussed herein while still providing the desired structural properties. In various embodiments, the housing includes a minimum wall thickness. In some embodiments, the total weight of the housing is less than the maximum weight. In such embodiments, the helmet shell has these thicknesses and/or weights while providing one or more of the structural features discussed herein.

The multiaxial impact toughness of Mewokie materials, material A and Material B were measured according to ISO 6603-2 at a temperature of-30 ℃ (+ -2 ℃) and a rate of 4.4 m/s. In certain embodiments, the mewoki material has an impact toughness greater than 27 joules. In particular embodiments, the mewoki material has an impact toughness of between 27 and 90 joules, specifically between 60 and 80 joules, more specifically between 65 and 75 joules.
