The present disclosure generally relates to protective headwear and, more particularly, to headgear within protective headwear.
Protective headwear typically includes headgear within the headwear to engage a wearer's head and support the protective headwear upon the wearer's head. Conventional headgear is uncomfortable, unstable on a wearer's head, and poor at accommodating different size heads.
Thus, a need exists for headgear that resolves one or more of these deficiencies.
In one aspect, it is desirable to have headgear that is comfortable, stable, and capable of adequately accommodating heads of varying size.
In one aspect, a headgear for protective headwear is provided and includes a pivotal forehead strap.

With particular reference to
In another example, an outer shell may be coupled to headgear in another manner. In this example, the outer shell may include a track or path defined in both sides thereof and the headgear may include a coupling member on each side thereof to cooperate with the respective track. Each coupling member may include a projection positioned within and slidable along the respective track. A securing member may be coupled to each coupling member and may be selectively engaged and disengaged to lock or secure the coupling members relative to the outer shell. In this example, each securing member may include a threaded member that may be turned in a first direction to tighten or secure the respective coupling member to the outer shell and inhibit movement of the headgear relative to the outer shell, and turned in a second direction to loosen or unsecure the respective coupling member from the outer shell to allow movement of the coupling member relative to the outer shell. This movement allows the wearer to adjust the outer shell relative to the wearer's head as desired. In this example, the coupling member and headgear translate or slide relative to the outer shell. In other examples, the tracks and coupling members may have different shapes, and the coupling members and the headgear may move in different manners than the illustrated translation. For example, the tracks may have arcuate shapes, at least in part, and the coupling members and the headgear 36 may move along an arcuate path relative to the outer shell. It should be understood that the headgear may be moveable relative to the outer shell in any desired manner and all of such possibilities are intended to be within the spirit and scope of the present disclosure. It should also be understood that the headgear may be coupled, locked or secured to the outer shell in any desired manner and all of such possibilities are intended to be within the spirit and scope of the present disclosure.
In another example, an outer shell may be coupled to headgear in another manner. In this example, the headgear allows pivot action between the outer shell and headgear. The headgear has laterally extending arms with a non-pivoting end. The non-pivoting end is coupled to a component which has a track that allows the non-pivoting end of the headgear arms to slide forward and backwards within that track. This allows the user to adjust a distance of the outer shell relative to their face. The component does not rotate and is fixed to the headgear with one degree of freedom allowing the components to slide forwards and backwards. The component is coupled to a second component. The second component is then coupled to the outer shell. The outer shell rotates with respect to the headgear as the second component pivots on the component. This pivot action is guided by posts that rotate within slotted holes. A bushing is coupled to the second component and placed between the component and the second component to reduce the frictional wear as the two components rotate about each other. A third component has a threaded hub through which a screw from the component threads. The third component can be rotated to adjust compressive forces for the pivot mechanism components sandwiched between the first and third components. This allows the user to control the frictional resistance of the pivot mechanism allowing control over angular velocity of the outer shell as it rotates about the headgear. The second component has a multitude of holes allowing fins protruding from the outer shell to slide into these holes locking the second component and the outer shell together preventing them from rotating about one another. The angle at which the second component is coupled to the outer shell is controlled by which the holes and the fins are slid into. This controls the tilt angle of the outer shell relative to the user's face. A fourth component is a snap-on piece that is non-rotatably coupled to the end of a threaded screw. As the first component remains fixed relative to the outer shell and the second component, the coupling of the fourth component to the first component allows it to also remain fixed. So as the third component is rotated to adjust the friction resistance, the fourth component will remain stationary relative to it.

Protective headwear 20 is commonly used in non-level orientations such as, for example, a downward angle (e.g., during welding, the welder is looking downward and forward toward the welding area), an upward angle (e.g., a wearer may be looking upward and overhead), etc. In such non-level orientations, the top strap 72 minimizes shifting of the protective headwear 20 relative to the wearer's head as a result of the top strap 72 extending over the crown or top of the wearer's head. The rear strap 76 is pivotally coupled at its ends 92 to respective side members 64 and is positioned to extend around a rear of a wearer's head. In the illustrated example, the top strap 72 and the rear strap 76 are oriented in a perpendicular manner relative to each other. In other examples, the top strap 72 and the rear strap 76 may be oriented in other manners relative to each other. The ends 88, 92 of the top and rear straps 72, 76, and their associated pivots or pivot points, are located in close proximity to each other on the side members 64, which may also minimize shifting of the protective headwear 20. In other examples, one or both of the top and rear straps 72, 76 may be rigidly and non-pivotally coupled to the side members 64.
In the illustrated example, the headgear 36 may be considered to include a single occipital strap 80 with two portions, one portion on each side of the headgear that are coupled together at a rear of the headgear 36 by the tightening member 84, or the headgear 36 may be considered to include two occipital straps 80, one occipital strap 80 on each side of the headgear and coupled together at a rear of the headgear by the tightening member 84. For purposes of the following description, which is not intended to be limiting one way or the other, but rather to demonstrate principles of the present disclosure, this example will reference two occipital straps 80 with one occipital strap 80 on each side of the headgear 36.
In one example, the occipital straps 80 are pivotally connected at ends 96 to respective side members 64, are positioned under the side members 64 (i.e., between the side members 64 and a wearer's head), extend rearward and downward relative to the side members 64, drop down below the rear strap 76, wrap around or extend along the occipital crest of a wearer, then extend under the occipital crest. The occipital straps 80 have a height or thickness that is smaller than a height or thickness of the top and rear straps 72, 76. The position of the occipital straps 80 allow pressure originating from the protective headwear 20 to be applied to bony structure (e.g., the occipital bone and crest of a skull) of the wearer's head where the wearer has less of a perception of pressure than on soft tissue of the wearer's head.
In the illustrated example, the occipital straps 80 are compliant to the wearer's head. The occipital straps 80 may be made of a variety of different materials and have a variety of shapes, as long as the occipital strap 80 is compliant.
In one example, pivots 98 where the occipital straps 80 pivotally couple at ends 96 to the side members 64 are positioned on a front half 99 of the headgear 36 or protective headwear 20. That is, if a vertical plane 101 was oriented through a center of the headgear 36 or a wearer's head when wearing the protective headwear 20 and extended from one side member 64 to the other side member 64 or from a wearer's ear to ear (rather than front to rear), the pivots 98 would be positioned to a front or front side of such a vertical plane 101. In other words, the pivots 98 would be positioned between the vertical plane 101 and a forward most part of the forehead strap 68. The pivots 98 define a pivot axis 97 about which each end of the occipital straps 80 pivots.
In one example, the pivots 98 of the occipital straps 80 are positioned in front of a pivot axis or shell axis 102 about which the outer shell 24 rotates relative to the headgear 36. In this example, the pivots 98 are located between the pivot axis 102 and a forward most part of the forehead strap 68.
In one example, the pivots 98 of the occipital straps 80 are positioned in front of and above the pivot axis 102 of the outer shell 24. In this example, the pivots 98 are located between the pivot axis 102 of the outer shell 24 and a forward most part of the forehead strap 68, and are between the pivot axis 102 of the outer shell 24 and an upper most part of the top strap 72.
In one example, the pivots 98 may be located above and forward of a wearer's ears (see
With reference to
In one example and with reference to
The high and forward pivots 98 of the occipital straps 80 may allow for a greater range of motion in the occipital straps 80 (see, e.g.,
The headgear 36 further includes a pad 100 coupled to the occipital straps 80 and positioned at a rear of the headgear 36. The pad 100 is capable of engaging a rear of the wearer's head to provide comfort and further support. When the tightening member 84 is tightened by pulling the occipital straps 80 and causing the occipital straps 80 to overlap to a greater extent at a rear of the headgear 36 (see
Referring now to
In this illustrated example, the occipital strap 80 includes a coupling 109 comprised of a hub 110 and an aperture 111 extending through the hub 110. The coupling 109 provides the location for pivots 98 to pivotally couple the occipital strap 80 to the respective side member 64 and provides the pivot axis 97 about which the occipital strap 80 pivots. The occipital strap 80 also includes an adjustment portion 112 and a body 113 extending between the coupling 109 and the adjustment portion 112. In the illustrated example, the adjustment portion 112 defines an adjustment aperture 114 therein including a flat or smooth side 115 and a jagged or saw-tooth side 117. The jagged side 117 of the adjustment aperture 114 includes a plurality of projections 118 engageable by the tightening member 84 to facilitate adjustment of the occipital strap 80. The adjustment aperture 114 may include any number of projections 118 and any size of projections 118. In the illustrated example, the body 113 has a first height or thickness 119, which is smaller or less than heights or thicknesses 121, 122 of both the coupling 109 and the adjustment portion 112.
In one example, the body 113 of the occipital strap 80 is at least partially arcuate. In one example, the body 113 of the occipital strap 80 is at least partially straight or linear and at least partially arcuate. In one example, the occipital strap 80 includes an arcuate portion and a straight or linear portion. In one example, the body 113 has a complex shape. As used herein, an object having a complex shape may refer to the object changing shape at least once. For example, the body 113 of the occipital strap 80 may have a complex shape if the body changes from being linear to being arcuate. In one example and with reference to the illustrated example, the body 113 has a complex shape and includes a first straight or linear portion 126, a first curved or arcuate portion 128, a second straight or linear portion 130 and a second curved or arcuate portion 132. Intersections of dashed lines 134 illustrated in
In one example, the occipital straps 80 extend from a position in a front half 99 of the headgear 36 or protective headwear 20 to a position in a rear half 123 of the headgear 36 or protective headwear 20. In one example, the occipital straps 80 extend from a position in front of the shell axis 102 about which the outer shell 24 rotates relative to the headgear 36 to a position rearward of the shell axis 102 about which the outer shell 24 rotates relative to the headgear 36. In one example, the occipital straps 80 extend from pivots 105 about which the forehead strap 68 rotates to a position rearward of the shell axis 102 about which the outer shell 24 rotates relative to the headgear 36. In one example, the occipital straps 80 extend from a position above the shell axis 102 to a position below the shell axis 102. In one example, the occipital straps 80 extend from a position in front of and above the shell axis 102 to a position rearward of and below the shell axis 102.
With continued reference to
Returning to the illustrated example, the forehead strap 68 includes two ends 104 with both ends 104 pivotally coupled to respective side members 64 adjacent the wearer's forehead. Human heads have a variety of forehead slopes and the pivoting forehead strap 68 accommodates such varying forehead slopes. As a wearer begins to place the headgear 36 on his/her head, the wearer will pull the headgear 36 down onto his/her head, the forehead strap 68 will slide down the wearer's forehead, and will terminate sliding down the wearer's head at an appropriate point on the wearer's forehead based on the slope of the wearer's forehead. It is likely that the remainder of the headgear 36 is not completely down and supported upon the wearer's head when the forehead strap 68 is in this position. The pivoting ends 104 or pivots 105 of the forehead strap 68 allow the remainder of the headgear 36 to continue to move downward until the top strap 72 engages the crown of the head and the headgear 36 is supported on the wearer's head. The pivoting forehead strap 68 will lie flat or substantially flat against a wearer's forward and evenly distribute pressure to the wearer's forehead, rather than apply a significant quantity of pressure at a single point or edge.
In the illustrated example, the pivots 105 of the forehead strap 68 are at the same positions as pivots 98 of the occipital straps 80, thereby causing the forehead strap 68 and the occipital straps 80 to pivot relative to the side members 64 about the same pivot axis. In other words, the pivot axis 106 of the forehead strap 68 and the pivot axis 97 of the occipital straps 80 are co-linear or substantially co-linear.
As can be seen in
In some examples, the pivoting forehead strap 68 may eliminate the need to include a tightening member that provides additional pressure to secure the headgear 36 to a wearer's head. In some examples, the forehead strap 68 may also include padding or other soft material on at least an interior surface thereof (and, alternatively, wrapped around the forehead strap 68) configured to engage a wearer's forehead and provide additional comfort. The pivoting forehead strap 68 also provides a self-adjusting feature that allows a wearer to adjust or move the protective headwear 20 and headgear 36 relative to their head and the pivoting forehead strap 68 accommodates that movement to resettle the headgear 36 and the protective headwear 20 on the wearer's head.
With continued reference to
In one example, by locating the pivots 98 of the occipital straps 80 above and forward of a wearer's ears in conjunction with the forehead strap 68 capable of pivoting about pivots 105, compressive force or pressure is directed to the forehead strap 68, which alleviates or decreases a constricting feeling, oftentimes experienced in conventional headgear, since the pressure or force is directed at major bone structures in a wearer's head and avoids applying compressing forces or pressures to areas of the wearer's head that are more likely to perceive pressure (e.g., soft tissue, concentration of nerves, etc.).
It should be understood that the headgear 36 may have a variety of shapes, sizes, and configurations and all of such possibilities are intended to be within the spirit and scope of the present disclosure.
It should be understood that the use of any orientation or directional terms herein such as, for example, “top”, “bottom”, “front”, “rear”, “back”, “left”, “right”, “side”, etc., is not intended to imply only a single orientation of the item with which it is associated or to limit the present disclosure in any manner. The use of such orientation or directional terms is intended to assist with the understanding of principles disclosed herein and to correspond to the exemplary orientation illustrated in the drawings. For example, the protective headwear 20 and headgear 36 may be utilized in any orientation and use of such terms is intended to correspond to the exemplary orientation of the protective headwear 20 and headgear 36 illustrated in the drawings. The use of these terms in association with the protective headwear 20 and headgear 36 is not intended to limit the protective headwear 20 and headgear 36 to a single orientation or to limit the protective headwear 20 and headgear 36 in any manner.
The Abstract of the disclosure is provided to allow the reader to quickly ascertain the nature of the technical disclosure. It is submitted with the understanding that it will not be used to interpret or limit the scope or meaning of the claims. In addition, in the foregoing Detailed Description, it can be seen that various features are grouped together in various embodiments for the purpose of streamlining the disclosure. This method of disclosure is not to be interpreted as reflecting an intention that the claimed embodiments require more features than are expressly recited in each claim. Rather, as the following claims reflect, inventive subject matter lies in less than all features of a single disclosed embodiment. Thus, the following claims are hereby incorporated into the Detailed Description, with each claim standing on its own as a separately claimed subject matter.
While various embodiments of the disclosure have been described, it will be apparent to those of ordinary skill in the art that other embodiments and implementations are possible within the scope of the disclosure. Accordingly, the disclosure is not to be restricted except in light of the attached claims and their equivalents.
The present application claims the priority benefit of co-pending U.S. Provisional Patent Application Ser. No. 62/012,483, filed Jun. 16, 2014, the content of which is incorporated by reference herein.
