<p id="p0030" num="0030">An exemplary embodiment of the present invention for a protective headgear 10 is shown in <figref idref="f0001 f0002 f0003">FIGS. 1-6</figref>. The protective headgear device 10 includes a circumferential member 11, or outer shell, that generally conforms to the shape of one's head and covering portions of one's head for protection. The circumferential member 11 includes a front section 14 (or forehead section) for covering the forehead, a back section 15 for covering the back or crown of the head, and a top section 17 for covering a top of the head. In addition, the circumferential member 11 includes two side sections 16A, 16B for covering the top sides of the head, ears, temples, jaws and sides of the head. The sections 14, 15, 16A, 16B and 17 are arranged to form a first opening 12 (<figref idref="f0001">FIGS.1</figref> and <figref idref="f0002">3</figref>) through which a user is capable of viewing, a second opening 48 (<figref idref="f0001">FIG. 1</figref> and <figref idref="f0002">3</figref>) through which a user's neck extends and an interior or internal volume 49 (<figref idref="f0001">FIG. 1</figref> and <figref idref="f0002">3</figref>) in which a head is positioned.</p>
<p id="p0031" num="0031">While the above describes aspects of the invention, the invention is not so limited and may not require all the referenced sections. For example, embodiments may include a circumferential member 11 that does not include the top section 17.</p>
<p id="p0032" num="0032">With respect to the embodiment illustrated herein, the back section 15 includes a central section 32 depending from the top section 17, between and spaced apart from backside sections 43, 44. This configuration, which is known to those skilled in the art, enables the headgear 10 to fit on different size heads. The backside sections 43, 44 have strap openings 37, 38 to receive a strap 39 (<figref idref="f0003">FIG. 6</figref>) to tighten the back section 15 of the circumferential member 11 to a head. However, the invention is not limited to the spaced back section 15 shown in the drawings and may, for example, include a back section that is a single integral section across the back of a user's head or integrally formed with side sections 16A, 16B and top section 17.<!-- EPO <DP n="10"> --></p>
<p id="p0033" num="0033">In addition, sections of the headgear 10 may be perforated for ventilation and hearing. For example, openings 20 at the top section 17 provide and apertures 21 adjacent one's ear on the side sections 16A, 16B provide ventilation, and assist in hearing and/or air pressure relief.</p>
<p id="p0034" num="0034">As shown in <figref idref="f0001">FIGS. 2</figref> and <figref idref="f0003">6</figref>, a chinstrap 18 is secured to each of the side sections 16A, 16B and extends under a user's chin to secure the device 10 on the head. Accordingly, the side sections 16A, 16B include openings 34, 35 for receiving a chin strap. The invention is not limited to the particular strap arrangement shown in the drawings and may include other arrangements. For example, there may be only one opening or a pair of openings on only one side section 16A, 16B and the other side may include a hook and loop substrate attached to an external surface to support a strap or end of strap.</p>
<p id="p0035" num="0035">The circumferential member 11 is preferably fabricated from a suitable foam material that is conformable and resilient, capable of absorbing energy and forces when contacted and deformed by a strike or blow. In an exemplary embodiment, the foam material is a thermoplastic elastomer, or polyolefin based, closed cell foam product that is molded in a foam compression injection molding process. As known to those skilled in the art, such injection processes use a base material in pellet form, which is heated and injected into a mold to form a closed cell foam material.</p>
<p id="p0036" num="0036">The thickness of the headgear 10 may vary at different locations along the circumferential member 11 including the head section 13 and side sections 16A, 16B. Thickness along the circumferential member 11 may range from between about 5 mm to about 30 mm depending on the locations. For example at a forehead area or front section 14 the thickness may be about 40.0 mm, at the back sections 43, 44 the thickness may be about 22.0 mm, and the interconnections 19 between ventilation openings 20 on the top section 17 may have a thickness of about 9.0 mm. Note, these dimensions are provided by way of example only and are not intended to the limit the invention to any particular dimension or combination of dimensions.</p>
<p id="p0037" num="0037">As described further, aspects of the invention include a novel configuration of components of ear or side head impact protection. As shown in <figref idref="f0001">FIGS. 1, 2</figref>, <figref idref="f0004">8</figref>, and <figref idref="f0005">10</figref>, the headgear 10 and/or circumferential member 11 includes a first internal recess 23A and a second internal recess 23B located on the side sections 16A, 16B respectively. More specifically, the first and second recesses 23A, 23B are positioned to cover a user's ears. The first recess 23A<!-- EPO <DP n="11"> --> forms a first lip 24A that defines a geometric outline of the recess 23A. In addition, the second recess 23B forms a first lip 24B that defines a geometric outline of the recess 23B.</p>
<p id="p0038" num="0038">In as much as both sides of the headgear 10 are identical, for purposes of conciseness, the description of a one side shall refer to the components of the other side of the headgear 10. To that end, and as shown in <figref idref="f0005">FIGS. 10</figref>, <figref idref="f0006">11A, 11B</figref>, impact plates 26A, 26B are disposed within respective recesses 23A, 23B. The impact plates 26A, 26B each have a shape conforming to that of the headgear 10, circumferential member 11, or sides sections 16A, 16B at the recesses 23A, 23B. More particularly, each plate 26A, 26B has an outwardly curving or domed-like shape as defined by raised mid-section 50 (<figref idref="f0008">FIG. 13</figref>) to fit within and conform to the curvature of the headgear 10 in the recesses 23A, 23B.</p>
<p id="p0039" num="0039">In addition, each plate 26A, 26B, has a circumferential edge 25A, 25B that defines a geometric outline of the plate 26A, 26B that corresponds to a geometric outline of the respective recess 23A, 23B. In addition, the plates 26A, 26B are dimensioned so the edges 25A, 25B of the plates 26A, 26B abut the lips 24A, 24B of the recesses 23A, 23B. As further shown, the impact plates 26A, 26B may have one or more apertures 36 and preferably have the same number of apertures 21 as that of the side sections 16A, 16B at recesses 23A, 23B. In preferred, aspects of the invention, the apertures 36 and 21 have the same geometric shape and are aligned for purposes of ventilation of air in and out of the headgear 10 during use.</p>
<p id="p0040" num="0040">The impact plates 26A, 26B are comprised of a rigid plastic material that also has sufficient flexibility or resiliency to conform to the configuration of the interior surface 13 of the circumferential member 11 (or internal surface 13 of the recesses 23A, 23B) and flex upon impact from a blow to the side sections 16A, 16B of the headgear 10.</p>
<p id="p0041" num="0041">In an exemplary embodiment, the impact plates 26A, 26B are constructed from an injection molding process using a plastic nylon material; however, other materials may be used. The thickness of the impact plates 26A, 26B may range from about 1.25 mm to about 5.0 mm, and are preferably about 4.0 mm thick, which provides sufficient rigidity and flexibility to absorb and/or disperse force applied by a blow to the head.</p>
<p id="p0042" num="0042">An adhesive, or other fastening mechanisms, may be used to secure the impact plates 26A, 26B to the internal surfaces 13 of the headgear 10 within the recesses. For example, a polyurethane adhesive may be used with a nylon plastic impact plate for securing or affixing purposes.<!-- EPO <DP n="12"> --></p>
<p id="p0043" num="0043">In another aspect of the invention, the headgear 10 may further include pads such as a first pad 27A and second pad 27B inserted into the respective recesses 23A, 23B and covering the impact plates 26A, 26B. Each pad 27A, 27B, has a circumferential edge 29 that defines a geometric outline or shape of the pad 27A, 27B that corresponds to that of the respective recesses 23A, 23B and/or plates 26A, 26B. The pads are preferably composed of the same material as that of the circumferential member 11 and formed using a compression injection molding process; however, other materials and manufacturing processes may be used to fabricate the pads.</p>
<p id="p0044" num="0044">In preferred embodiments, the pads 27A, 27B have one or more apertures 46, and preferably the same number of apertures 21, 36 as that of the recesses 23A, 23B and impact plates 26A, 26B. To that end, each aperture 46 has the same geometric shape as the corresponding aperture 21, 36 with which it is aligned. The pads 27A, 27B, may have a thickness ranging from about 4.0 mm to about 8.0 mm, preferably about 6.0 mm. In preferred embodiments, a combined thickness dimension of the plates 26A, 26B and pads 27A, 27B does not exceed, is less than or is not significantly greater than a thickness dimension of the lips 24A, 24B. An adhesive may be used to affix the pads 27A, 27A to the impact plates 26A, 26B as described above with respect to the attachment of the impact plates 26A, 26B to the circumferential member 11 within recesses 23A, 23B. The pads 27A, 27B are preferably affixed to the impact plates 26A, 26B, but not to surfaces 13 of the circumferential member 11 within the recesses 23A, 23B.</p>
<p id="p0045" num="0045">With respect to <figref idref="f0007">FIGS. 12A, 12B</figref>, an embodiment is illustrated that includes an adaptation of the circumferential member 11 at the respective recesses 23A, 23B. More specifically, first and second undercuts 28A, 28B extend circumferentially around the respective recesses 21A, 21B between the lips 22A, 22B and surface 13 of the recesses 21A, 21B. The impact plates 26C, 26D are adapted relative to impact plates 26A, 26B so that portions of the impact plates are disposed within the undercuts.</p>
<p id="p0046" num="0046">With respect to <figref idref="f0008">FIG. 14</figref>, impact plates 26C and 26D are shown in more detail. As shown, the impact plates 26C, 26D each includes a mid-section 50 that is raised or offset relative to an outer rim 38A, 38A, similar to the impact plates 26A, 26A providing the curvature or domed configuration associated with the circumferential member 11 at the recesses 23A, 23B. Circumferential edges 30 extend along the corresponding outer lips 38; and, in an embodiment<!-- EPO <DP n="13"> --> the edges 30 and at least portions of the outer rims 38 are insertable into undercuts 28A, 28B to position the impact plates 26C, 26D in the headgear device 10, as shown in <figref idref="f0007">FIG. 12B</figref>. The impact plates 26C, 26D are otherwise similar in configuration, shape, dimension, materials as that of impact plates 26A, 26B and may be secured with an adhesive to the surface 13 in the recesses 23A, 23B and to the pads 27A, 27B as described above with respect to the first embodiment.</p>
<p id="p0047" num="0047">In any of the above-described embodiments, the headgear 10 and circumferential member 11 include internal one or more pressure relief channels associated with internal volume 49 of the headgear 10. More specifically, as shown in <figref idref="f0004">FIGs. 8</figref> and <figref idref="f0005">10</figref>, pressure relief channels 42A, 42B, and 42C are positioned adjacent to the recesses 23A, 23B to provide air flow communication between an interior of the headgear 10 and circumferential member 11 and an exterior thereof. The thickness of the circumferential member at the channels 42A, 42B, 42C may vary according to their locations and a depth dimension of each channel 42A, 42B or 42C. For example, the depth of each channel 42A, 42B, 42C may be about 6.0 mm, and the width of the channels may vary and may be from about 15.0 mm to about 25.0 mm wide. For example, channel 42A may be about 25.0 mm wide, and channels 42B, 42C may be about 20.0 mm wide.</p>
<p id="p0048" num="0048">It is noted that channels 42A are disposed on the side sections 16A, 16B at generally an eye level of a user and are capable of receiving eyewear frame members of a user. Accordingly, pressure relief channels 42A may be characterized as eyewear receiving channel</p>
