The present invention relates generally to the field of hard hats and helmets. The present invention relates specifically to a sun-visor and/or other safety equipment accessories attached to a hard hat. Hard hats are often used in loud and brightly illuminated areas, for example, a construction site on a sunny day. Work environments at various job sites may enable the use of added safety equipment (e.g., earmuffs and/or a face protector) to provide added
protection to the user. A sun-visor may protect the user's face and/or neck from sunburn and/or falling overhead debris. A lamp or flashlight may assist with vision in poorly lit or low visibility environments or during a change from an illuminated to a dim work environments. Additional ear protection or earmuffs help protect the user's hearing in noisy environments.
One embodiment of the invention relates to a hard hat system including a hard hat and a visor. The hard hat includes a shell formed from a rigid material and an accessory mounting location located along an outer surface of the shell. The visor is reversibly coupled to the hard hat. The visor includes a first portion and a second portion. The first portion extends circumferentially around at least a portion of the shell and extends radially outward from the shell forming a sun-blocking flange. The second portion is coupled to the first portion and is positioned adjacent to the accessory mounting location. The second portion is deformable relative to the first portion such that the second portion deforms to accommodate and cover a portion of an accessory coupled to the accessory mounting location allowing the accessory to extend from the accessory mounting location to below the second portion.
Another embodiment of the invention relates to a hard hat system including a hard hat and a visor. The hard hat includes a shell formed from a rigid material. The visor is reversibly coupled to the hard hat. The visor includes a front portion and a rear portion. The front portion is moveable between a covering configuration in which the front portion extends in a forward direction away from a front of the hard hat, and a stowed configuration in which the front portion extends in a rearward direction away from a rear of the hard hat.
Another embodiment of the invention relates to a hard hat system including a hard hat comprising a shell formed from a rigid material, a clip coupled to the hard hat, and a visor. The clip includes an engaging portion including an upper surface and a lower surface. Each of the upper surface and the lower surface face in an upward direction. The clip is configured to couple to the hard hat in a first position or in a second position. The upper surface engages with the hard hat when the clip is in the first position and the lower surface engages with the hard hat when the clip is in the second position. The upper surface is spaced a distance above the lower surface. The visor is coupled to the clips such that the visor is reversibly supported to the hard hat via the clip and extends circumferentially around a portion of the hard hat.
One embodiment of the invention relates to a hard hat attachment system. The hard hat includes a mounting location comprising opposite dovetailed ridges projecting outward on either side of the mounting location. Each ridge includes a transition to couple slots of a bracket and support an accessory (e.g., lamp, face shield, and/or visor). Each ridge extends outwardly from the mounting location to create projections that support the mounted accessory. A sun-visor, e.g., an extended brim or visor, is coupled to the hard hat at the mounting location or the extended ridge to shade a wear's eyes, face and/or neck, to protect the user from sun/UV rays and/or falling debris, etc.
Another embodiment of the invention relates to a visor configured for selective attachment to a hard hat. The visor includes an inner and outer diameter. The visor includes a front brim and a rear brim. The front brim is positioned to extend outward from a front surface of the hard hat, and the rear brim is positioned to extend outward from a rear surface of the hard hat. A stretch zone extends radially from the inner diameter to the outer diameter and is located between and interconnects the front and rear brims. A fastener is coupled to the stretch zone and is configured to couple to an accessory ridge on the hard hat to removably secure the visor to the hat. In some embodiments, the visor includes a bracket positioned to engage one or more mounting locations on the hard hat to secure the visor to the hard hat. In a specific embodiment, the bracket is positioned on the front or rear visor to engage a front or rear mounting ridge of the hard hat.
In various embodiments, the visor includes a single stretch zone allowing an outer diameter of the visor to expand to accommodate different sized hard hats. In this embodiment, the single stretch zone is located between opposing ends of two visor sections allowing the size/circumference/inner diameter of the visor to be adjusted to accommodate different sized hard hats.
In various embodiments, the front brim includes a first end facing a first end of the rear visor and a second end facing a second end of the rear visor. In this arrangement, a first stretch zone is coupled between the first ends of the front and rear visors, and a second stretch zone is coupled between the second ends of the front and rear visors. In this arrangement, by having a plurality of stretch zones, e.g., on opposite sides of the visor sections, a parallel stretch sun-visor is provided that stretches in a direction between the front brim and the rear brim allowing for a distance between front and rear visors be expanded between a minimum distance and a maximum distance. In this configuration, the flexibility of the material of the stretch zones also provides for folding locations located on each side of the visor between the front and rear visors. This allows the user to fold the front brim over onto the back brim, and vice versa, to customize the brim location of the visor.
Another embodiment of the invention relates to a modular visor. The modular visor has a first module or brim section or segment that partially extends around the hard hat's perimeter. The modular visor enables a user to customize combinations of brim segments and/or accessories. For example, the user couples the rear modular brim section to a face shield in the front of hard hat. The user customizes a first modular brim section made from a semi-transparent material in front and couples it to a second modular brim section made from an opaque material in back. The modular sun-visor is used in variation with other accessories and/or segments. Segmentation of the modular visor enables the user to combine different modules made from different materials or features.
Another embodiment of the invention relates to a hard hat visor including enclosed elastic areas within a brim of the visor. The enclosed elastic areas extends radially outwards from the inner diameter of the visor towards the outer diameter and are located on opposite lateral sides of the brim. Specifically, the enclosed elastic areas are located adjacent to the auxiliary ridges of the hard hat and extend outwards from the auxiliary ridge a radial distance that is less than the distance to outer diameter. As such, the elastic areas do not extend across the entire radial length of the visor between the inner and outer edges and form an elastic inner brim coupled to a rigid outer brim. The elastic area expands or deflects when accessories are attached to the auxiliary ridge. For example, support arms of earmuffs or face shields are coupled to ports in the auxiliary ridge by deflecting elastic areas, but otherwise without removing or adjusting the visor. In this way, the earmuffs are removed and rotated off the user's ear without removing or adjusting either the hard hat or the visor.
Another embodiment of the invention relates to a sun-visor with a front brim and a rear brim coupled with two opposite stretch zones. The sun-visor has a wire that extends along the outer diameter. The front brim includes a semi-transparent material and a pad along the inner diameter of the front brim. The pad creates a buffer that deflects for different sizes or styles of hard hats. The stretch zones couple to the auxiliary ridge at a pivot joint that biases the visor about an outer perimeter of the hard hat. The stretch zones and pad deflect to accept variations in sizes for accessories attached in the mounting locations or ports of the auxiliary ridge without removing or adjusting the visor. The pad fits over and/or around additional accessories attached at mounting locations of the hard hat (e.g., a face shield). The visor folds about a spring-loaded joint or biased pivot to adjust a frictional clamping force of an inner diameter of the visor against the outer perimeter of the hard hat. The biased pivot also includes a joint that couples the sun-visor to a mounting location or auxiliary ridge of the hard hat.
In various additional embodiments, the sun-visor is configured for any style or size of helmet or hard hat (e.g., a traditional or climbing style) that includes the mounting locations and/or auxiliary ridge. In this way a universal mounting system that includes mounting locations and auxiliary ridges is compatible with a variety of accessories and configured to work with the visors described herein. The visor can include a bracket that couples to a front or rear mounting location. For example, a notch located on a face of the mounting location secures and removably locks the bracket against the mounting location. For example, the notch can fit within an inner recess of bracket to lock bracket against the notch at the mounting location. In another embodiment, the visor slides under the notch along the outer perimeter of the hard hat and bracket is coupled over the visor to compress visor and securely lock the visor under the notch.
Alternative exemplary embodiments relate to other features and combinations of features as may be generally recited in the claims.
This application will become more fully understood from the following detailed description, taken in conjunction with the accompanying figures, wherein like reference numerals refer to like elements in which:
Referring generally to the figures, a hard hat accessory system is shown and described. Hard hats include both traditional brimmed style hard hats and climbing style helmets, e.g., with only a small bill in front. Unless specifically indicated, Applicant has used the term “hard hat” to include traditional and climbing style hard hats, as well as any hard hat or protective helmet design, including hard hats having a universal mounting system with mounting locations and auxiliary ridges. Different sizes and styles of hard hats present challenges to the uniform mounting system's size and dimensions. The universal mounting system includes both front and rear mounting locations and opposite side auxiliary ridges. The mounting system provides uniform sized attachments and locations to mount various accessories on various sizes and styles of hard hats. Applicant has found that a visor accessory mounted to the uniform mounting system can also provide the operator multiple access sites at the mounting ridges and side ports to mount additional personal/safety equipment. This enables a user to customize the hard hat for the job site and personal preferences, which enhances user compliance and the proper use of adequate safety equipment based on the job specifications. As used herein, accessories generally include lamps (or headlights), face shields, and/or earmuffs, but can also include a reflector, a magnetic tool carrier, or tool/fastener carrier, hand/power tools, and/or an eyeglass/safety glass holder.
A visor extends the brim of hard hat to shade the user's eyes, to protect the user's eyes from direct sunlight at a construction site, to block/shield the eyes/front of the face from light debris and dust, etc. Attachment of various additional accessories to the mounting system of hard hat can sometimes interfere with other previously mounted equipment. For example, an operator may frequently wear and take off earmuffs at the job site, which would require the operator to adjust both the visor and the earmuffs on/off the hard hat. Applicant has found that support on the mounting system for the rotation of earmuffs when not in use, e.g., off and behind the user's ears, enables the user to switch frequently wear and storage of the earmuffs. The ability to switch between a use and stored position enhances user comfort, particularly when the switch minimizes the adjustments to other attached accessories, such as a visor. Thus, in various embodiments, discussed below, Applicant has developed an innovative modular visor which includes relief portions, such as flexible expanding segments and/or portions that are less taut than neighboring portions, which allows the user to adjust earmuffs without needing to remove the visor. Applicant has also developed an innovative modular visor that permits the user to fold a front and/or side portion of the visor towards the rear, thus permitting the user to attach other accessories and/or attachments to a front and/or side of the hard hat without requiring the user to remove the visor.
As illustrated, hard hat 10 is oriented in a forward-facing direction with a front mounting location 16 above a visor, ridge, bill, or brim 12 of the front 14 of hard hat 10. In this configuration, front brim 12 is located at the front 14 of hard hat 10, shields the operator's eyes, e.g., from the sun. In the illustrated position, a rear 15 of hard hat 10 is in the back of the user's head and provides a smaller brim 12 to shade to the user's neck.
A strap or band 32 wraps around the circumference of hard hat 10 without interfering with the mounting locations 16 or auxiliary ridges 26. For example, band 32 passes through openings under auxiliary ridges 26. Band 32 supports hand tools and/or other equipment suitable for storage along brim 12 or auxiliary ridges 26 of hard hat 10. Similarly, various accessories 18 attach or couple to ports 34 in an auxiliary ridge 26 of hard hat 10. In some embodiments, tools and/or other accessories 18 include an insert, fastener, or receiving slot 30 that couples with one or more ports 34.
The composite image of bill 42 and brim 12 hard hats 10 is shown on the left of
Often the user attaches various accessories 18 at different locations (e.g., mounting location 16 and/or ports 34) to maximize utility (e.g., accommodate more accessories 18) and/or comfort. The composite image on the right shows earmuffs 38 in the rear port 34. In this position, earmuff 38 extends substantially parallel to axial axis 40 and over the user's ears, when earmuffs 38 are in the shown operating position. For example, a user places earmuff 38 in the third or rear port 34 because this attachment location for earmuff 38 is closer to a centerline, or axial axis 40, of the operator's neck (e.g., the base of the user's head). Alternative positions for accessories 18 may aid with shade and/or muscle comfort, e.g., by keeping the mass or CG as close to the axial axis 40 at the centerline.
Stated differently, accessories 18 fit differently on hard hats 10 of different styles and/or geometries. However, where the mounting locations 16 and/or auxiliary ridges 26 are the same, or similar, for different hard hats 10, they interchangeably receive accessories 18 with a complimentary mounting bracket 24 (or insert).
Visor 48 couples under mounting locations 16 and auxiliary ridge 26 along an outer perimeter 88 of hard hat 10. Visor 48 deflects to rotate/move earmuff 38 from below the visor 48 in an operation position 56 to a stored position 58 for earmuff 38 above the visor 48, as shown in
Visor 60 provides a space, or bridge, for accessories 18, such as lamp 20, to remain attached to hard hat 10 when an operator moves the face shield 22 from an operation position 56 to a stored position 58 and back. Visor 60 also provides a reliable structural abutment, or seal, between the face shield 22 and any style of hard hat 10 with mounting locations 16 (or auxiliary ridges 26) configured for the bracket 24 on visor 60. In this way, visor 60 facilitates coupling a welding face shield 22 and a lamp 20 to the mounting location 16. As a specific example, this configuration is beneficial when welding, since traditional welding face shields 22 are dark to protect the eyes from the arc, but often too dark to see in ambient light. Operators often find it difficult to see and manipulate work-piece objects when the face shield is in the operating position but the welding arc is not illuminated. Lamp 20 can provide sufficient light for the operator to see and manipulate the welding work-pieces before and after the welding process in the absence of the arc.
Visor 60 provides a structural and spatial bridge between hard hat 10 and face shield 22 for structural support of another attached accessory 18. This enables two accessories 18 (e.g., a welding mask and a headlamp) to be coupled at the mounting location 16 of hard hat 10. Ridge extensions 62 on visor 60 (e.g., bracket 24 of visor 60) provide a structural offset or bridge from hard hat 10 to visor 64 to accessory 18.
Visor 60 has a bracket 24 with a duplicate mounting location 16 on an exterior of visor 60 to accommodate the additional mounted accessory 18. For example, on one side (e.g., an inner surface) of visor 60 is a mounting bracket 24 with ridges 25 similar to lamp 20. When this bracket 24 of visor 60 couples to mounting location 16, an opposite, exposed side (e.g., outer surface) of visor 60 forms an available external mounting location 16 to receive and support an additional mounted accessory 18, such as a lamp 20, on hard hat 10.
To support accessory 18 and/or visor 60, each mounting location 16 has side ridges 25 on both sides of mounting location 16. Mounting bracket 24 has a complimentary side receiving slots 30 on both sides of mounting bracket 24. Side receiving slots 30 are configured to couple to ridges 25 at the mounting locations 16. For example, the coupling of receiving slots 30 to ridges 25 mounts visor 60 to hard hat 10 and similarly mounts a lamp 20 to visor 60 (
Applicant has found that having a mounting location 16 for the face shield 22 with the same, or similar, ridge extension 62 dimensions ensures the proper abutting visor 64 position for the face shield 22 in the operation position 56 to protect a user's eyes and/or face. Ridge extension 62 structurally interconnects face shield 22 over the brim 12 of hard hat 10. In one embodiment, ridge extension 62 and face shield 22 abut to form a seal, such as a watertight or hermetic seal. The seal then protects the user from intruding or splashed liquids or debris.
Different users prefer different bills 42, brims 12, and/or hard hat 10 geometries. Different geometries are also advantageous for various worksites and/or jobs. For example, the same user may have one hard hat 10 with a large bill 42 for outdoor worksites and a second hard hat 10 with a small surrounding brim 12 to support a lamp 20 for indoor job sites.
Applicant has found that using an intermediary modular visor 60 enables the user to attach one face shield 22 that reliably abuts and/or seals against the brim 12 of a variety of hard hats 10. Visor 60 creates a reliable fitment regardless of the style, size, or geometry of the brim 12 or bill 42 on the hard hat 10. In this way, an operator with two hard hats 10 can attach, abut, and/or seal the same face shield 22 to visor 60, and then interchangeably attach and detach the visor 60 and face shield 22 to the operator's preferred hard hat 10. This enables the operator to customize the hard hat 10 for a particular environment or job. Alternatively, the same user attaches a welding face shield 22 for a welding job and later attaches a different protective eyeglass face shield 22 for woodworking. In other words, visor 60 bridges different sizes and shapes of various hard hats 10 (or face shields 22) and permits the use of one face shield 22 to fit various sizes of hard hats 10 with complimentary mounting locations 16.
In one embodiment, visor 60 includes an oblong locking protrusion 66 in mounting location 16. An overhang 68 on bracket 24 engages a notch or notch 69 to lock visor 60 on mounting locations 16 of hard hat 10. The coupled notch 69 and overhang 68 protect against inadvertent bumping or jostling of accessories 18 when visor 60 is coupled to hard hat 10.
Visor 60 attaches to both styles and creates a uniform ridge extension 62 with a consistent brim width W. The brim width W extends between the mounting location 16 of hard hat 10 to an edge of the ridge extension 62 on visor 60. As shown, the brim width W is greater than either bill 42 or brim 12 dimensions. The middle row shows how the visor 60 creates a uniformly sized attachment for an accessory 18 or face shield 22. The bottom row shows how brim width W is longer than either extension of bill 42 or brim 12 styles. Specifically, the black visor 60 is longer than either the bill 42 (left) or brim 12 (right) of either hard hat 10.
In a specific embodiment, hard hat system 8 includes hard hat 10 including a shell 11 formed from a rigid material and visor 70 reversibly coupled to hard hat 10. The shell 11 includes an accessory mounting location 16 located along an outer surface 7 of shell 11.
In various embodiments, visor 70 includes a first portion 130 and a second portion 132. The first portion 130 extends circumferentially around at least a portion of the shell 11 and extends radially outward from the shell 11 forming a sun-blocking flange. The second portion 132 is coupled to the first portion 130 and positioned adjacent to the accessory mounting location 16. The second portion 132 is deformable relative to the first portion 130 such that the second portion 132 deforms to accommodate and cover a portion of an accessory 18 (e.g., an ear muff) coupled to an accessory mounting location, shown as one of front port 80, middle port 82, or rear port 84. The deformation of second portion 132 allows accessory 18 to extend from the accessory mounting location (e.g., front port 80, middle port 82, or rear port 84) to below the second portion 132.
In various embodiments, second portion 132 is formed from a material that is more elastic than a material of the first portion 130. In various embodiments, second portion 132 includes a first zone 134 on a first side 136 of shell 11, and a second zone 138 on a second side 140 of shell 11 opposite the first side 136. In a specific embodiment, the first side 136 is a left side of the shell 11 and the second side 140 is a right side of the shell 11. In various embodiments, a fastener, shown as joint 72, couples the visor 70 to the left side of the shell 11 and a second fastener, shown as joint 72, couples the visor 70 to the right side of the shell 11. In various embodiments, second portion 132 includes a third zone 142 and a fourth zone 144 separated by a bridge 78, and the third zone 142 and the fourth zone 144 are both positioned on a first side of the shell 11 (e.g., a left side of the shell 11, a right side of the shell 11). The bridge 78 is formed from a material that is less elastic than a material forming the second portion 132.
As described in detail below, visor 70 enables a user to fold a brim 12, e.g., front over the back or back over the front, and retain the fold. Visor 70 couples to mounting locations 16 and/or ports 34 of auxiliary ridge 26 on different styles and sizes of brim 12 and/or bill 42 hard hats 10 (e.g., climbing styled helmets and traditional hard hats 10).
With reference to
Front brim segment 74 is moveable between a covering configuration in which the front brim segment 74 extends in a forward direction 71 away from a front 14 of hard hat 10, and a stowed configuration in which the front brim segment 74 extends in a rearward direction 73 away from a rear 15 of the hard hat 10. Front brim segment 74 interfaces with the rear brim segment 76 when the front brim segment 74 is in the stowed configuration.
In various embodiments, clip 24 is coupled to rear brim segment 76 and clip 24 couples visor 70 to hard hat 10 (
In various embodiments, joint 72 couples to a port 34 in auxiliary ridge 26. For example, as shown in
In various embodiments, bracket 24 is coupled directly to visor 70 (
In various embodiments, visor 70 includes a first folding location 86 on a first side 81 of visor 70, and a second folding location 87 on a second side 79 of visor 70 opposite the first side 81. In various embodiments, first folding location 86 includes a stretch zone 77 that is more elastic than neighboring portions of visor 70 (e.g., portions of visor 70 adjacent to stretch zone 77).
Strap 94 can be coupled to front brim segment 74 and/or rear brim segment 76. Joint 72 can be biased or unbiased to provide folding locations 86 for rotation of either modular section. Joints 72 couple front brim segment 74 to rear brim segment 76. Joints 72 also couple modular visor 100 to auxiliary ridge 26. In other embodiments, a compressive force generated by stretch zones 77 expanded about outer perimeter 88 retains visor 100. Various shims 104 are located around outer perimeter 88 to adjust modular visor 100 to the size, shape, and/or style.
In some embodiments, joint 72 includes mating protrusions 106 and slots 108 between front brim segment 74 and rear brim segment 76. For example, protrusions 106 couple or snap into slots 108 to couple the front and rear segments 74 and 76 of modular visor 100. In various embodiments, joint 72 includes other mechanisms for temporarily and securely joining segments of modular visors 100, such as hook and loop joints, pressure/friction generating joints, metal and/or plastic quick-release joints, fasteners, buckles, and/or adhesives.
As illustrated, no physical connection exists between modular visor 100 and folded visor 70. This configuration enables the functional coupling or pairing of a modular visor 100 and a folded visor 70. Modular visor 100 is used in combination with other accessories 18 and/or sun-visors (e.g., visors 48, 67, and/or visor 70, or another visor described herein). For example, two or more modular visors 100 (e.g., a front brim segment 74 and a rear brim segment 76) are combined to extend around the outer perimeter 88 of hard hat 10 entirely. Front brim segment 74 and rear brim segment 76 of modular visor 100 can be different materials and/or have different transparencies (e.g., transparent, semi-transparent, or opaque). In addition, front brim segment 74 and/or rear brim segment 76 are interchangeably removed and replaced with one or more accessories 18 to fit the operator's preferences, safety, and/or use at the specific job site.
In some embodiments, modular visor 100 includes one or more materials and/or stretch zones 77 to adjust the frictional clamping force of inner diameter 90 of visor 100 on outer diameter 92 of hard hat 10. In various embodiments, the frictional clamping force and/or bracket 24 couple visor 100 to hard hat 10. Bracket 24 either forms a part of brim segment 74 or 76 (e.g., is affixed to) or fits over and captures brim segment 74 and/or 76 against hard hat 10 (e.g., is not joined but proximate to segments 74 and 76).
Visor 150 also couples rear brim segment 76 to both front ports 80 and rear mounting location 16. This configuration creates a stable visor 150 connection and also enables the operator to insert and attach earmuffs 38 to auxiliary ridge 26 through elastic area 152. Specifically, the operator passes a four-bar support arm 156 linkage for either face shield 22 or earmuffs 38. Support arm 156 passes into or through elastic area 152 and couples inserts 158 (at the terminus of support arm 156) into the remaining middle or rear port 82 or 84 of each opposite auxiliary ridge 26 (
In various embodiments, face shield 22 can be a convertible face shield 22 that attaches to hard hat 10 when visor 100 is folded towards the rear 15 of hard hat 10 (
Visor 160 mounts around hard hat 10 perimeter 88 with a coupled accessory 18 (face shield 22) at a front mounting location 16 of hard hat 10. This configuration demonstrates how the features and/or materials of visor 160 interact with various attached accessories 18 (e.g., four-bar linkages, support arms, and/or inserts) at mounting locations 16 and/or auxiliary ridges 26.
As illustrated in
A front pad 162 along the inner diameter 90 of a front transparent brim segment 74 provides a tolerance 165 to fit visor 160 on different sizes and shapes of various accessories, hard hats 10, and helmets. Two opposite and parallel stretch zones 77 are located adjacent auxiliary ridge 26 and extend from inner diameter 90 to outer diameter 92 of brim 12. A spring-loaded or biased fastener creates a biased pivot 164 (e.g., similar to joint 72) that couples stretch zones 77 of visor 160 to a port 34 on auxiliary ridge 26 (e.g., front port 80, middle port 82, or rear port 84). Biased pivot 164 creates the bias or spring force against visor 160, such that the operator applies a downward force on visor 160 to create a clamping frictional force at the inner diameter 92 on brim 12. Stretch zones 77 include a stretched flexible material that extends from inner diameter 90 to outer diameter 92 to create a compressive force on outer perimeter 88 and enable pad 162 and visor 160 to deflect for different sizes, shapes, and styles of hard hat 10. A wire 166 extends along outer diameter 92 of visor 160 to create a rigid outer diameter 92.
An optional bracket 24 couples to a rear segment 76 of visor 160. Bracket 24 couples or captures visor 160. Pad 162 slides under a notch 69 at mounting location 16 of hard hat 10. As illustrated, mounting location 16 is coupled to face shield 22, and pad 162 fits under notch 169 to couple to the outer perimeter 88 of hard hat 10 with the attached accessory 18. Stretch zones 77 are elastic/flexible adjacent auxiliary rides 26, but wire 166 forms a rigid/firm outer diameter 92 of visor 160. This configuration enables multiple materials in semi-transparent or tinted front and rear segments 74 and 76, stretch zones 77, and pad 162 to form expandable features at the joint between outer perimeter 88 of hard hat 10 and inner diameter 90 of visor 160. In contrast, outer diameter 92 is relatively rigid and firm through the various materials due to wire 166. In one embodiment, stretch zones 77 extend over and/or deflect around both support arms 156 and inserts 158 that attach face shield 22 and/or earmuffs 38.

Frame 240 is coupled to safety headwear, shown as hard hat 210, at one of a plurality of mounting slots along the side of hard hat 210. In the specific embodiment shown, frame 240 is coupled to a middle port 214 of hard hat 210. In a specific embodiment, frame 240 is formed in an arch, U or horseshoe-shape and is formed from a plastic material.
Folding portion 232 includes a frontal relief portion, shown as front flap 226, configured to receive various accessories, such as the arms of ear muffs. Similarly, side portion 222 includes a rear relief portion, shown as rear flap 228, configured to receive various accessories, such as the arms of ear muffs. In use, front portion 234 and folding portion 232 can be folded up and over the dome of hard hat 210 and backwards towards rear portion 224 (see
In a specific embodiment, visor 220 includes first portion 221 and second portion 223. Similar to various embodiments of visor 70, second portion 223 is more deformable than the first portion 221 such that the second portion 223 deforms to accommodate and cover a portion of an accessory (e.g., an arm of an ear muff) coupled to an accessory mounting location below second portion 223. In a various embodiments, second portion 223 is less taut than first portion 221. In various embodiments, second portion 223 includes front flap 226 and rear flap 228. For example, second portion 223 is more deformable without being stretched compared to how deformable first portion 221 is without being stretched (e.g., because second portion has extra fabric that is not as taut). As another example, second portion 223 extends upwardly and loosely upwards against an exterior of the shell (see

Clip 244 includes an engaging portion 258 that includes a first surface, such as an upper surface, shown as upper step surface 256, and a second surface, such as a lower surface, shown as lower step surface 254, each of upper step surface 256 and lower step surface 254 facing in an upward direction 257. In use, when coupling clip 244 to helmet 212, upper step surface 256 or lower step surface 254 is coupled to helmet 212. In particular, clip 244 is coupled to hard hat 210 in a first position or in a second position. The upper step surface 256 engages with the hard hat 210 when the clip 244 is in the first position and the lower step surface 254 engages with the hard hat 210 when the clip 244 is in the second position. In a specific embodiment, the upper step surface 256 is spaced a distance 253 above the lower step surface 254. Therefore, clip 244 is inserted lower into the body of helmet 212 compared to hard hat 210, and as a result the angle of frame 240 and visor 220 provides more consistency when coupled to different embodiments of safety headwear. In a specific embodiment, engaging portion 258 is biased in a horizontal direction against hard hat 210.

Frame 420 couples to safety headwear, such as hard hats, via coupling mechanisms, shown as hooks 422 (e.g., hooks 422 engage with ridges 25 of mounting location 16 of hard hat 10, see
Frame 420 includes one or more coupling elements, shown as engaging portions 460. Engaging portions 460 are substantially the same as engaging portions 258 except for the differences discussed herein. In particular, engaging portions 460 include an extension that extends vertically above the body of engaging portions 460.
In use, hooks 422 are slideably engaged with the hard hat to restrict frame 420 to vertical movement relative to the hard hat, and tabs 448 bias frame 420 from moving upward and disengaging from the hard hat. To remove frame 420 from the hard hat, a user pulls lever 440 in upward direction 442. In response, pivot 446 interfaces against the hard hat, which forces tabs 448 away from the hard hat until tabs 448 do not interface with the protrusion extending from the hard hat. As a result, the user can slide frame 420 upward relative to the hard hat to disengage frame 420 from the hard hat.
