Crown 100 is configured to couple to safety headwear and a head of a person wearing the safety headwear. Arms 104 of crown 100 couple crown 100 to outer shell, such as at coupling components 36 of outer shell 20. Upper band 106 of crown 100 is fixedly coupled to outer shell 20 via arms 104. Front band 118 of upper band 106 circumferentially surrounds a front a user's head, thereby helping secure crown 100 to the user's head.
1001321 Middle frame 108 is pivotably coupled to upper band 106 and pivots with respect upper band 106 around axis 110. The positioning of axis 110 between middle frame 108 and upper band 106 closer to the back of the user's head (compared to other designs) permits easier rotation of crown 100 with respect to the user's head as the user's head moves.
1001331 Middle frame 108 defines apertures 114, which couple to securing component, shown as ratchets 112. Ratchets 112 can be loosened with respect to middle frame 108 to permit middle frame 108 to be adjusted to the shape of a user's head. When the adjustment has been made to conform to the user's head, ratchets 112 can be tightened to fixedly couple upper band 106 to
-13-middle frame 108 such that upper band 106 no longer pivots with respect to middle frame 108.
If further adjustments need to be made, then ratchets 112 can once again be selectively loosened and tightened.
[00134] Adjustable band 120 is coupled to middle frame 108 and pivots with respect to middle frame 108 about axis 116. The pivotable coupling between adjustable band 120 and middle frame 108 contributes to user comfort by permitting adjustable band 120 to more easily alter its position and/or configuration as the user is moving around. For example, if the user pivots his head back to look straight up, the back of the user's neck will correspondingly arch backwards. When the user's neck is in that configuration, adjustable band 120 pivots downwards with respect to middle frame 108 to match the contours of the user's neck, thereby avoiding and/or mitigating the adjustable band 120 digging into the user's neck and negatively affecting the user's comfort.
1001351 Adjustable band 120 includes first arm 122, which is coupled to middle frame 108, and second arm 124, which is also coupled to middle frame 108. First arm 122 and second arm 124 can be adjusted with respect to body 146 of adjustable band 120, thereby extending or retracting the overall length of adjustable band 120 along arcuate axis 154. A
user can adjust the positioning of first arm 122 and second arm 124 with respect to body 146 by actuating an interface, shown as button 140. As shown in FIGS. 16 and 17, crown 100 is at or near a minimum adjustable circumference 152 and/or diameter 150. To adjust circumference 152 and/or diameter 150 of crown 100, a user presses button 140. When button 140 is pressed, first arm 122 and second arm 124 can be either extended or retracted along arcuate axis 154 with respect to body 146, thereby lengthening or shortening adjustable band 120.
[00136] Turning to FIGS. 18-19 in particular, first arm 122 includes aperture 126, which includes teeth 128. Teeth 128 of first arm 122 interface with a protrusion, such as teeth, of body 146. First end 130 of first arm 122 is coupled to middle frame 108. Second end 134 of first arin 122 is opposite first arm 122. First end 130 defines aperture 132, at the center of which is axis 116. When first arm 122 is extended distance 136, teeth of body 146 engage at or near the left-most tooth in FIG. 19. When first arm 122 is retracted to distance 138, teeth of body 146 engage at or near the right-most tooth in FIG. 19. In a specific embodiment, distance 136 is 145 mm and
If further adjustments need to be made, then ratchets 112 can once again be selectively loosened and tightened.
[00134] Adjustable band 120 is coupled to middle frame 108 and pivots with respect to middle frame 108 about axis 116. The pivotable coupling between adjustable band 120 and middle frame 108 contributes to user comfort by permitting adjustable band 120 to more easily alter its position and/or configuration as the user is moving around. For example, if the user pivots his head back to look straight up, the back of the user's neck will correspondingly arch backwards. When the user's neck is in that configuration, adjustable band 120 pivots downwards with respect to middle frame 108 to match the contours of the user's neck, thereby avoiding and/or mitigating the adjustable band 120 digging into the user's neck and negatively affecting the user's comfort.
1001351 Adjustable band 120 includes first arm 122, which is coupled to middle frame 108, and second arm 124, which is also coupled to middle frame 108. First arm 122 and second arm 124 can be adjusted with respect to body 146 of adjustable band 120, thereby extending or retracting the overall length of adjustable band 120 along arcuate axis 154. A
user can adjust the positioning of first arm 122 and second arm 124 with respect to body 146 by actuating an interface, shown as button 140. As shown in FIGS. 16 and 17, crown 100 is at or near a minimum adjustable circumference 152 and/or diameter 150. To adjust circumference 152 and/or diameter 150 of crown 100, a user presses button 140. When button 140 is pressed, first arm 122 and second arm 124 can be either extended or retracted along arcuate axis 154 with respect to body 146, thereby lengthening or shortening adjustable band 120.
[00136] Turning to FIGS. 18-19 in particular, first arm 122 includes aperture 126, which includes teeth 128. Teeth 128 of first arm 122 interface with a protrusion, such as teeth, of body 146. First end 130 of first arm 122 is coupled to middle frame 108. Second end 134 of first arin 122 is opposite first arm 122. First end 130 defines aperture 132, at the center of which is axis 116. When first arm 122 is extended distance 136, teeth of body 146 engage at or near the left-most tooth in FIG. 19. When first arm 122 is retracted to distance 138, teeth of body 146 engage at or near the right-most tooth in FIG. 19. In a specific embodiment, distance 136 is 145 mm and
-14-distance 138 is 65 mm. In various embodiment second arm 124 has a similar and symmetrical configuration and functionality as first arm 122.
1001371 Turning to FIGS. 20-22, depicted is crown 100 in a slightly extended configuration with respect to FIGS. 15-17. In the configuration in FIGS. 20-22, button 140 has been actuated and first arm 122 has been slightly extended with respect to body 146.

1001391 Turning to FIGS. 23-26, various aspects of strap system 200 are shown.
Strap system 200 is substantially similar to strap system 14 and other strap systems described herein, except as otherwise described and depicted. In various embodiments, strap system 200 is configured to couple a suspension system, such as crown 100, to a head of a person, and thus also couple safety headwear to the head of a person. In various embodiments, strap system 200 is configured to couple safety headwear to a head of a person. Strap system 200 includes side straps 202, which couple to outer shell 20 via side clips 210 at or near a front-side of a user, such as near the user's temple. Back straps 204 couple to outer shell 20 via back clips 212 at or near a back of the user's head. In use, as a user pulls down on chin strap 206, ratchet 166 of adjustable band 160 rotates with respect to the user's head to the configuration shown in FIG.
23. In a specific embodiment, strap system 200 includes a first strap, such as side strap 202 or a back strap 204, that couples to a clip (e.g., clip 546 shown in FIGS. 78-81). In a specific embodiment, side strap 202 is positionable below a chin of a user of a hard hat when a clip coupled to the strap and a receiver coupled to the hard hat are coupled together.
1001401 Chin strap 206 extends underneath a front portion of user's face, such as underneath the user's chin. Side straps 202, back straps 204, and chin strap 206, are coupled together via coupler 208. In a specific embodiment, chin strap 206 includes adjustor 218, which can be actuated by a user to extend or retract a total distance of chin strap 206, thereby adjusting the position of coupler 208 with respect to outer shell 20 and the user's face. In a specific embodiment, coupler 208 permits chin strap 206 to rotate with respect to coupler 208 (similar to the functionality of clip 546, shown in FIGS. 78-81 and described below), thereby facilitating the
1001371 Turning to FIGS. 20-22, depicted is crown 100 in a slightly extended configuration with respect to FIGS. 15-17. In the configuration in FIGS. 20-22, button 140 has been actuated and first arm 122 has been slightly extended with respect to body 146.
1001381 Turning to FIGS. 23-85, various designs for strap systems are shown.
In various embodiments the strap systems designed are sized for users with larger heads and/or users with headgear, and functionality is provided to shorten the length of strap systems by users with smaller heads as necessary.
1001391 Turning to FIGS. 23-26, various aspects of strap system 200 are shown.
Strap system 200 is substantially similar to strap system 14 and other strap systems described herein, except as otherwise described and depicted. In various embodiments, strap system 200 is configured to couple a suspension system, such as crown 100, to a head of a person, and thus also couple safety headwear to the head of a person. In various embodiments, strap system 200 is configured to couple safety headwear to a head of a person. Strap system 200 includes side straps 202, which couple to outer shell 20 via side clips 210 at or near a front-side of a user, such as near the user's temple. Back straps 204 couple to outer shell 20 via back clips 212 at or near a back of the user's head. In use, as a user pulls down on chin strap 206, ratchet 166 of adjustable band 160 rotates with respect to the user's head to the configuration shown in FIG.
23. In a specific embodiment, strap system 200 includes a first strap, such as side strap 202 or a back strap 204, that couples to a clip (e.g., clip 546 shown in FIGS. 78-81). In a specific embodiment, side strap 202 is positionable below a chin of a user of a hard hat when a clip coupled to the strap and a receiver coupled to the hard hat are coupled together.
1001401 Chin strap 206 extends underneath a front portion of user's face, such as underneath the user's chin. Side straps 202, back straps 204, and chin strap 206, are coupled together via coupler 208. In a specific embodiment, chin strap 206 includes adjustor 218, which can be actuated by a user to extend or retract a total distance of chin strap 206, thereby adjusting the position of coupler 208 with respect to outer shell 20 and the user's face. In a specific embodiment, coupler 208 permits chin strap 206 to rotate with respect to coupler 208 (similar to the functionality of clip 546, shown in FIGS. 78-81 and described below), thereby facilitating the
-15-chin strap 206 maintaining a more flush and therefore more comfortable configuration with respect to the user's neck.
1001411 In various embodiments back straps 204 extend through cavity 164 of adjustable band 160. Adjustable band 160 is substantially similar to adjustable band 120, except as shown and depicted herein. Ratchet 166 of adjustable band 160 permits the user to adjust the position of first and second arms of adjustable band 160 with respect to the body, thereby extending or retracting the length of adjustable band 160.

Strap system 400 is substantially similar to strap system 14 and other strap systems described herein, except as otherwise described and depicted. Strap system 400 is coupled to shell 20 via front clip 402 and rear clip 406. Front clip 402 has a diameter that is different than diameter 408 of rear clip 406.
The different diameters/shapes of front clip 402 and rear clip 406 help the user quickly identify if the user is attempting to insert front clip 402 or rear clip 406 into an incorrect location on outer shell 20 (e.g., by trying to insert front clip 402 into the location where rear clip 406 is inserted).
1001541 Chin strap 206 of strap system 400 includes a buckle 410 that is configured at or near coupler 208 on one side of user's face (shown in FIG. 58). This positioning of buckle 410 improves the user experience by reducing the chaffing of the buckle 410 against the user's head when the user is talking and/or moving (e.g., as compared to if the buckle 410 is proximate the user's throat). Additionally, the side positioning of buckle (shown in FIG.
58) improves the ability of the user to see the buckle and confirm they are orienting the buckle as desired, it is easier for the user to access a buckle on the side as compared to locating the buckle under the user's chin, and the side-positioning of buckle 410 permits increased length adjustments of the chin strap 206 compared to other designs.
1001551 Turning to FIGS. 59-61, various aspects of strap system 420 are shown.
Strap system 420 is substantially similar to strap system 14 and other strap systems described herein, except as otherwise described and depicted. Clip 422 permits the adjustment of side strap 430 by wrapping side strap 430 around clip 422 before inserting clip into outer shell 20. Clip 422 includes side arms 424, which couple clip 422 to outer shell 20. In a first configuration, side strap 430 extends from clip 422 without wrapping around center arm 426, thereby providing a relatively longer length of side strap (shown in FIG. 60). In a second configuration, side strap
In use, a user can look at the positioning of the side strap 382 on the left side of his face with respect to the gradations, and configure the other side strap 382 to the same or a similar positioning. This provides the user an efficient way to symmetrically configure the outer shell on the user's head.
Back straps 384 also include gradations providing a similar mechanism to facilitate user adjustments.

Clip 422 permits the adjustment of side strap 430 by wrapping side strap 430 around clip 422 before inserting clip into outer shell 20. Clip 422 includes side arms 424, which couple clip 422 to outer shell 20. In a first configuration, side strap 430 extends from clip 422 without wrapping around center arm 426, thereby providing a relatively longer length of side strap (shown in FIG. 60). In a second configuration, side strap
-19-430 is wrapped around center arm 426, thereby shortening the length of side strap 430 by two times height 428 of center arm 426 (shown in FIG. 61) ("two times" because side strap 430 needs to both extend up to the top of center arm 426 and transit that same distance down to the bottom of clip 422). In use, users shorten side strap 430 by wrapping side strap 430 around center arm 426. Alternatively, users lengthen side strap 430 by unwrapping side strap 430 from center arm 426. An advantage of the design of strap systems 420 is that the straps will not slide because the strap length adjustment is a fixed length. Another advantage is that no special tooling or dexterity is required to adjust the strap length.
