[0039] Referring generally to the accompanying drawings, various embodiments of protective work / construction helmets, shown as safety helmets, are illustrated. The various embodiments of the safety helmets discussed herein include various impact layer designs that provide improved shock absorption capabilities (e.g., the impact force of falling objects, lateral impacts of objects, impacts from tripping / falling) while maintaining a light weight. In various embodiments, the impact layer is formed of a rigid material and has protrusions with a generally conical shape. In a specific embodiment, the impact layer includes protrusions with a truncated conical shape. The applicant believes that the shape of the impact layer provides improved energy absorption and increased durability compared to conventional protective layers (e.g., expanded polystyrene (EPS) foam).

[0040] Furthermore, the design of the impact layer, and more specifically, the design having multiple protrusions rather than a uniform layer, provides increased airflow within the helmet, thereby increasing wearer comfort (e.g., reducing temperature). In various embodiments, the impact layer is attached to the helmet via a bracket, shown as a peripheral support. The peripheral support is positioned along the inner surface of the helmet. In various embodiments, a central support is positioned on the side of the impact layer opposite to the peripheral support. The applicant believes that the attachment of the impact layer discussed herein allows for a secure attachment between the helmet and the impact layer, without the use of connectors such as screws, which may make replacing the impact layer difficult, compared to conventional helmet attachments that may require permanent connectors such as screws or hot melt adhesives. Instead, in the various embodiments discussed herein, the peripheral support and the central support have a snap-fit ​​design for attachment to the helmet and / or the impact-absorbing layer.

[0041] Reference Figure 1A perspective view of a protective work or construction helmet, illustrated as a safety helmet 10, according to an exemplary embodiment, is shown.

In a specific embodiment, the second end of the protrusion 242 has a reduced size compared to the first end. In other words, when each of the plurality of protrusions has a tapered shape, the first end of the protrusion 242 has a first size, and the opposite second end of the protrusion 242 has a second size. In such an embodiment, the second size is different from the first size. In a specific embodiment, the second size is smaller than the first size. In a specific embodiment, the first size and the second size are the diameters of the protrusions 242.

[0061] Reference Figures 7 to 8 Details of the impact-absorbing layer 340 located within the helmet 110 are shown according to another exemplary embodiment. Except for the differences discussed herein, the impact-absorbing layer 340 is substantially the same as the impact-absorbing layers 140, 240.
