Background

[01] The present specification relates to a headgear or suspension of the type used in a head safety product such as a face shield, hardhat or welding helmet. More

particularly, the specification is directed to a self-adaptive, elastomeric nape belt to improve the fit, function, stability and comfort of the headgear.

Summary of the Disclosure

[02] An improved self-adjusting headgear for a head safety product, such as a face shield, hardhat or welding helmet, includes an elastomeric nape belt to improve the fit, function, stability and comfort of the headgear. The nape belt is elastomeric and has relief openings to facilitate conformation of the nape belt to the shape of the head. The nape belt acts as a conformable tension springto buffer or absorb the tension between the horizontal head band and the head and more equally distribute pressure across the head. In anexemplary embodiment, the nape band is located in the rear of the headgear to engage the occipital area of the head and includes spaced anchor openings to provide a wide range of adjustment.

[03] I n the exemplary embodiment, the head safety product comprises a hard hat having a domed shell and a brim.

[04] The headgear for the head safety product comprises a headband at least

partially encircling the wearer's head and a plurality of hangers extending from the headband to support the headgear within the dome of the hard hat. The headband has a front portion configured to extend across a forehead area of the user and further has opposing rearward ends which are free floating and not connected. The front portion of the headband has opposing straps which are provided with interfitting formations that allow adjustable size positions.

H0047920 The headgear further comprises a crown strap assembly engaged with the headband and extending over the top of the users head. At the rearward ends of the horizontal strap, opposing strap extensions extend downwardly and rearwardly to lower the position of the nape belt and to provide anchor point to for the nape belt.

The nape belt is formed from an elastomeric material and has an elongated central body portion and opposing end portions extending from the central body portion. The opposing end portions are respectively anchored to the opposing strap extensions whereby the elastomeric nape-belt extends across the occipital areas of the wearer's head and elastomerically self-adjusts to the wearer's head.

The opposing end portions of said nape belt include a plurality of longitudinally spaced anchor openings which releasably engage with hooked anchors on the headband extensions. The headband extensions also include slots wherein the end portions of the nape belt extend through the slots and engage the hook anchors. Elastic tension of the nape belt is adjusted by selecting between the anchor openings.

In order to better conform to each individual wearer, the central portion of the nape belt has an upwardly curved upper peripheral edge and a downwardly curved lower peripheral edge. This arrangement displaces tension from the nape belt toward the occipital bone areas of the head rather than centrally at the top of the neck.

Additionally, the central body portion of the nape belt has three vertically extending, longitudinally spaced openings to further facilitate elastomeric conformation of the nape belt to the occipital areas of the wearer's head. In the exemplary embodiment, the central relief opening is generally oval in shape while the two outer relief openings are symmetrically opposing generally trapezoidal openings having longer dimensions extending toward the upper and outer corners.

Accordingly, an objective is to provide a headgear that improves fit, function, stability and comfort.

H0047920 [09] Another objective is to provide a nape belt for a headgear that is flexible and self-adjusting.

[10] Yet another objective is to provide a headgear that conforms to and engages the head below the equatorial region to provide an improved fit.

[11] Still another objective is to provide an elastic nape belt that buffers tension and more equally distributes pressure between the headband and the head.

[12] Finally, it is yet another objective to provide a headgear which is readily

adaptable to both new head safety products and head safety products already deployed in the field.

[13] Other objects, features and advantages shall become apparent as the description thereof proceeds when considered in connection with the accompanying illustrative drawings.

Detailed Description of the Exemplary Embodiment

[25] Generally, an improved headgear with self-adaptive nape belt is illustrated and described hereinto improve the fit, function, stability and comfort of the headgear.The headgear includes an elastomeric, flexible, spring-like nape belt connected across the rear portion of the headband. The elastomeric napebelt adjustably secures the headband in a manner that buffers tension between the headband and the head and more equally distributes pressure across the head resulting in better comfort.

[26] Referring to the drawing figures, the exemplary embodiment of the head safety product is a hard hat assembly 10 comprising a hard hat 12 and the present headgear assembly 14. While the exemplary embodiment is illustrated in conjunction with a hard hat, it should also be understood that the headgear is equally contemplated for use in other head safety products, including but not limited to face shields, welding helmets, head lamps, medical head gear and products, wearable head equipment, and consumer headgear and products.

[27] The hard hat 12 is conventional in the art and generally includes a domed shell

16 and a brim 18. The interior of the hard hat 12 includes various attachment points 20 for securing the headgear 14 within the dome 16 (see Fig. 2).

[28] The headgear 14 for the head safety product comprises a horizontally extending headband 22 at least partially encircling the wearer's head and a plurality of hangers 24 extending from the headband 14 which engage the attachment points 20 to support the headgear 14 within the dome 16 of the hard hat 12. The headband 22 has a front portion configured to extend across a forehead area of the user and further has opposing rearward ends26,28which are free floating and not connected. The front

H0047920 portion of the headband 22 has opposing straps 30,32which are provided with interfitting and interlocking formations 34 that allow user adjustable coarse sizing positions. The headband 22 can be molded or otherwise formed from a flexible plastic material as would be suitable for the purpose.

The headgear 14 further comprises a crown strap assembly 36 engaged with the headband 22 and extending over the top of the users head. The crown strap assembly 36 can be made from plastic or fabric straps, or other suitable material for comfort.

At the rearward ends of the horizontal strap, opposing strap extensions

38,40extend downwardly and rearwardly to lower the position of the elastomeric nape belt 42 and to provide anchor point to for the elastomeric nape belt 42.

The nape belt 42 is formed from an elastomeric material and has an elongated central body portion 44 and opposing end portions 46,48extending from the central body portion 44. The opposing end portions 46,48are respectively anchored to the opposing strap extensions 38,40 whereby the elastomeric nape belt extends across the occipital areas of the wearer's head and elastomerically self-adjusts to the wearer's head.

The opposing end portions 46,48of the nape belt 42 include a plurality of longitudinally spaced anchor openings 50 which releasably engage with hooked anchors 52 on the headband extensions 38,40. The headband extensions 38,40also include slots 54 wherein the end portions 46,48 of the nape belt 42 extend through the slots 54 and engage the hook anchors 52. Elastic tension of the nape belt 42 is adjusted by selecting between the spaced anchor openings 50.

It can also be seen that the end portions 46,48 include an offset shoulder 46A,48A which moves the curvature of the central portion 44 inwardly in relation to the curvature of the end portions 46,48 (see Fig.10). This arrangement moves the central portion 44 of the nape belt 42 inwardly toward the wearer's head and improves comfort by helping to prevent the plastic headband extensions 38,40from rubbing against the

H0047920 wearer's head.

In order to better conform to each individual wearer, the central portion 44 of the nape belt 42 has an upwardly curved upper peripheral edge 56 and a downwardly curved lower peripheral edge58 (See Figs.8 and 9). This arrangement displaces tension from the nape belt 42 toward the occipital bone areas of the head rather than centrally at the middle of the neck. Additionally, the central body portion 44 of the nape belt 42 has three vertically extending, longitudinally spaced relief openings 60,62,64to further facilitate elastomeric conformation of the nape belt 42 to the occipital areas of the wearer's head. In the exemplary embodiment, the central relief opening 60 is generally oval in shape while the two outer relief openings 62,64are symmetrically opposing generally trapezoidal openings having longer dimensions extending toward the upper and outer corners thereof.

In summary, it can be appreciated from the foregoing description and illustrations that the shape and configuration of the elastomeric nape belt42 is such that it conforms to and gently cups the head below the equatorial region and gently grips around the mastoid bone area (occipital area) creating a more secure fit for various shaped heads. The napebelt 42 is completely passive and requires no additional effort by the end user to use or adjustonce the nape belt 42 is initially adjusted by selecting the anchor points to set it to the appropriate width. In use, the nape belt42 self-adjusts and deflects the appropriate amount depending on the shape of the wearer's head. The nape belt 42 is also self-aligning allowing it to gently conform in shape to the user's head and seat itself in a manner that equally distributes contact and pressure on the rear of the user's head. Because the nape belt 42 works in a cupping manner securely below the equatorial region of the head, it provides a secure fit and feeling with far less tension and pressure than a standard headgear arrangement.

For these reasons, the present headgear 14 is believed to represent significant advancements in the art, which have substantial commercial merit.

H0047920 Whi le there is shown and described herein certain specific structure embodying the present headgea r, it will be manifest to those skilled in the art that various modifications and rearrangements of the parts may be made without departing from the spirit and scope of the underlying concept and that the same is not limited to the pa rticu lar forms herein shown and described except insofar as indicated by the scope of the appended claims.
