- the ear cups 116 a - 116 b then hang in a free pivoting mode, or they may be held in place by a feature (not shown) such as a catch, detent, ratchet, clasp, etc. In this position, recognizing that the ear cups are extended, the helmet 100 may automatically select a decreased volume for ear cup speakers.
- the wearer pivots the ear cups rearward, ultimately engaging the tabs 720 with the features 118 . Greater force applied to the ear cups in this way more snugly engages them with the frame 408 in tighter fit.
Abstract
A helmet includes a shell with an impact resistant exterior surface formed by an upper shell and a rear shell. The upper shell is shaped to protect a top portion of a wearer's head, the rear shell shaped to protect an occipital portion of the wearer's head. A headset assembly, attached to the shell, includes dual ear cups rotatable about an axis that is above the wearer's ears when the helmet is worn. The ear cups have at least the following positions: an extended position to cover the wearer's ears, and a retracted position substantially abutting both upper and rear shell to the rear of the wearer's ears. The ear cups are shaped so that they form a surface substantially flush with the exterior surface while the ear cups are in the retracted position.
Description
- 1. Field of the Invention
- The present invention relates to safety helmets. More particularly, the invention concerns a helmet with ear cups that pivot into a position that is flush with the helmet, generally above and behind the wearer's ears.
- 2. Description of the Related Art
- Today, there is a vast array of safety equipment available to workers. Steel-toed boots protect the feet from heavy weights or impact. Fire and heat resistant clothing helps protect the body against flame. Eye goggles and face shields ward off debris and bright lights to protect the eyes.
- Probably one of the most common items of safety equipment is a helmet or “hard hat.” These are frequently used by construction workers, building inspectors, shipbuilders, factory workers, and others. However, conventional hard hats typically leave the wearer's ears exposed and vulnerable to impact damage. Of course, some people use ear plugs to protect their hearing, but this still leaves their ears unprotected from possible impact. Other people might use aftermarket ear muffs to protect against hearing loss, and this might provide some incidental protection against impact injury to the ears. However, aftermarket ear muffs can be difficult to wear with a conventional hard hat. There are some products with integrated hard hat and ear muffs, but these typically protrude from the helmet in some direction, and necessitate an irregular outer surface of the helmet. Therefore, they are vulnerable to snagging on wiring, insulation, vehicle interior, brush, and other features of the wearer's work environment.
- Thus, when selecting a safety helmet and ear protection there are many different tradeoffs. Further complicating this, certain users might wish to listen to audio signals while using a safety helmet. Yet, finding an audio system that is compatible with the helmet and ear protection can be difficult or impossible.
- Consequently, known safety helmets are not completely adequate for some applications due to certain unsolved problems.
- A helmet includes a shell with an impact resistant exterior surface formed by an upper shell and a rear shell. The upper shell is shaped to protect a top portion of a wearer's head, the rear shell shaped to protect an occipital portion of the wearer's head. A headset assembly, attached to the shell, includes dual ear cups rotatable about an axis that is above the wearer's ears when the helmet is worn. The ear cups have at least the following positions: an extended position to cover the wearer's ears, and a retracted position substantially abutting both upper and rear shell aft of the wearer's ears. The ear cups are shaped so that they form a surface substantially flush with the exterior surface while the ear cups are in the retracted position.

- Overall Structure
- One aspect of the present disclosure concerns a safety helmet. Although the safety helmet may be embodied by various hardware components and interconnections,
FIG. 1 shows one specific example in the form ofhelmet 100. - Broadly, the
helmet 100 comprises a safety helmet with ear cups that pivot between an extended position and a retracted position that is flush with the helmet, generally above (and also behind) the person's ears. Although not part of thehelmet 100, awearer 150 is shown for reference and perspective. - The
helmet 100 includes afront end 102 and arear end 104. One part of the helmet is a rigidupper shell 105 to protect the wear's head from impact injury. Theupper shell 150 is made of a suitable material for this purpose, such as polycarbonate or another suitable reinforced or non-reinforced material. - Within the
upper shell 105 are defined a number ofvents 124, which in the illustrated example comprise aerodynamic channels with apertures leading to the interior of thehelmet 100. Thevents 124 permit air exchange between the wearer's head and outside the helmet without taking rain in. - The
helmet 100 is shaped to form avisor 106, which protrudes well forward of the wearer's face. Thevisor 106 affords some protection of the wearer's face from sun, rain, and falling debris. Integral with a lower side of thevisor 106 is an arc-shapedfront lens 108, which protects a multiple beam light (not shown in this view) such as an LED array.FIG. 1 reveals a portion of an eye shield 107 (in retracted position). Theshield 107 is illustrated and described in greater detail below. - At the rear 104 of the
helmet 100, there is arear shell 110 and a curvedrear lens 114. Within therear shell 110, there is an electrical connector (not visible inFIG. 1 ) for attaching electronic equipment of thehelmet 100 to various off-helmet electrical equipment. Components at the rear 104 of the helmet are described in greater detail below. - The
helmet 100 also includes ear cups, one 116 b of which is visible in the view ofFIG. 1 . The ear cups pivot about respective axes, such as theaxis 120 of the ear cup 116 b. The ear cups are held in a retracted position, to the rear of the wearer's ears (e.g., 152) by one of various mechanisms described below. In the illustrated example, there is a friction fit between the ear cup 116 b and anengaging feature 118 of a frame (not shown). The frame is illustrated and discussed in greater detail below. In their retracted position, the ear cups are substantially flush with the upper/rear shells 105/110, and more particularly, they present a surface that is substantially continuous with the arc and shape of therear shell 110 andupper shell 105. By minimizing any protrusion from the helmet, the ear cups present a contiguous part of the helmet when retracted. -
FIG. 2 shows thehelmet 100 from the wearer's left side. This view demonstrates some of thehelmet 100's movable parts. Namely, theeye shield 107 and an ear cup 116 a are shown in their respective, extended positions. -
FIGS. 3A-3B show thehelmet 100 in rear view, in two different configurations. In one configuration (302,FIG. 3A ), ear cups 116 a-116 b are extended. In another configuration (304,FIG. 3B ), the ear cups 116 a-116 b are retracted. Both configurations 302-304 illustrate the rear 104 of the helmet, including features such as therear lens 114 andrear shell 110. -
FIG. 4 shows an exploded view of thehelmet 100 to better illustrate the individual pieces' shapes and interconnections. Optionally, thehelmet 100 includes vent plugs 412. In one example, the vent plugs 412 include apertures (not shown) that are pressed over studs (not shown) protruding from theshell 105's inner surface (i.e., the surface toward the wearer). In this example, the vent plugs are secured in place with Tinnerman clips. Of course, other means of attachment may be employed such as shape fit, fasteners, clips, glue, press fit, screws, rivets, etc. Eachvent plug 412 comprises an elastomeric member with protrusions shaped to fit inside corresponding holes of thevents 124. While thehelmet 100 is not being worn, the wearer can insert/remove the vent plugs 412 into/from thevents 124 by bendably manipulating theplugs 412. - Beneath the
shell 105 is aframe 408. Theframe 408 serves as a common attachment point for theupper shell 105,rear shell 110,rear lens 114,front lens 108, and other components described below. - A number of additional components are coupled to the
frame 408. One such component is theconnector 112. Theconnector 112 comprises an electrical coupling for electrically attaching helmet electronics (described below) to off-helmet electrical equipment. In one example, the connector is a six position IEEE 1394 receptacle such as Molex part 53984-0611. In the illustrated embodiment, theconnector 112 is mounted to a printed circuit board (PCB), which is attached to theframe 408. - The
connector 112 is coupled to other electrical components aboard thehelmet 100, as described in greater detail below. Some of these components include an electronics module and headset assembly, and these may be electrically coupled to theconnector 112 by one or more wiring harnesses, electrical buses, PCB traces, wires, Bluetooth or other wireless links, etc. Theconnector 112 may be removably engaged with another connector (not shown), electrically attached to various off-helmet components. Some examples of these off-helmet components include a listen-only audio source such as a flash-memory based music player (such as MP3, iPod, etc.), AM/FM or satellite radio, CD player, etc. Another example is a two-way transceiver, such as a wireless phone, two-way radio, etc. As still another example, off-helmet components may include an antenna, pack of one or more rechargeable or disposable batteries, etc. In the illustrated example, theconnector 112 is compatible with a six position IEEE 1394 plug (not shown) such as a Tyco part 787950-1. This female plug is compatible with a male counterpart attached via cabling (not shown) to the off-helmet electronics. At a remote end of this cabling, there may be one or more 2.5 mm jacks to interface with audio equipment, cell phones, etc. - Another component attached to the
frame 408 is theelectronics module 406. Among other components, themodule 406 includes a source of light that projects through thefront lens 108 when themodule 406 is mounted to theframe 408. Thus, in thefinished helmet 100, themodule 406 andlens 108 are built into thevisor 106 ofFIG. 1 . Themodule 406 is mounted to the top side of theframe 408, as viewed inFIG. 4 . - Another component, attached to the
frame 408, is aneye shield guide 402. Theguide 402 provides a base for slidable movement of theeye shield 107, defines full up and down travel, and removably secures theshield 107 in a user selected position. Theguide 402 and its attachment to theframe 408 are described in greater detail below. - Another component, attached to the
frame 408 is aheadset assembly 430. Primary components of the headset assembly are the ear cups 116 a-116 b and theband 413, to which the ear cups 116 a-116 b are mounted. Theassembly 430 and its attachment to theupper shell 105 are described below. - Still another component of the
helmet 100 is theheadband assembly 414. Theassembly 414 provides an adjustable harness to provide a snug fit to the wearer's head, which supports thehelmet 100 during use. Theassembly 414 mounts to theframe 408 by four supports 416-419. Theassembly 414 and its attachment to theframe 408 are discussed below. -
FIGS. 5A-5B illustrate some of the components ofFIG. 4 in assembled form. Namely,FIG. 5A shows a top perspective view of theframe 408,headband assembly 414, supports 416-419, eye shield guide 402 (witheye shield 107 removed), andelectronics module 406.FIG. 5B shows a bottom oblique view of thehelmet 100, where the following components are visible: theframe 408,headband assembly 414,lens 108, guide 402,eye shield 107,support 416, ear cups 116 a-116 b,rear shell 110, vent plugs 412,connector 112, andupper shell 105. - Headband Assembly
-
FIG. 6 shows theheadband assembly 414 in greater detail. As mentioned above, theheadband assembly 414 provides an adjustable harness so that the wearer's head can comfortable and securely support thehelmet 100. In one example, theassembly 414 includes aheadband base 602 coupled to crisscrossingstraps straps base 602 includesmechanism 614 to adjust the base to fit different head sizes. - In the illustrated example, the
headband assembly 414 is attached to the base 408 at the supports 416-419. More particularly, the supports 416-419 are attached by fasteners, clips, glue, press fit, screws, rivets, detent or other shape fit, etc. Theheadset assembly 430 attaches to theshell 105 as discussed above. Thebase 408 attaches to theshell 105 by fasteners, clips, ultrasonic bonding, glue, press fit, screws, rivets, detent or other shape fit, etc. Thus, in the final construction, theheadset assembly 430 is positioned over theheadband assembly 414, permitting theassembly 414 to comfortably direct the weight of thehelmet 100 upon the wearer's head. - Headset Assembly
-
FIG. 7 shows theheadset assembly 430 in greater detail. Broadly, theassembly 430 includes the ear cups 116 a-116 b, which pivotably attach to theband 413. Theband 413 includesstuds 704 about which the ear cups 116 a-116 b are free to rotate, as discussed below. In one example, theband 413 is made of spring steel, and thestuds 704 include Press-in studs such as PEM part THFS-632-6. Theband 413 also includesholes 724 for use in attaching theband 413 to theupper shell 105. For example, theband 413 may be screwed or riveted to theshell 105 viaholes 724. In a different example, theholes 724 may receive barbed studs (not shown) projecting from theshell 105, in order to secure theband 413 to theshell 105. Of course, other arrangements may be used such as fasteners, clips, glue, press fit, shape fit, etc. - Each ear cup is comprised of an
ear pad 710,inner shell 712,acoustic foam 714, andouter shell 716. Theshells shells ear cushion 710 comprises water impenetrable material such as GORE-TEX® material surrounding padding of neoprene foam. In another example, the ear cushions 710 are gel or foam filled plastic or another durable yet soft material to provide cushioning between the wearer's head and theassembly 430. - Each
inner shell 712 includes apivot housing 723 to permit free rotation of the respective ear cup about anaxis 722 through thepivot housing 723. In one example, eachpivot housing 723 is implemented by a drilled or tooled or vacuum molded hole theshell 712. Astud 704 protrudes through each such hole, enabling the ear cup can to pivot about this hole. The ear cups 116 a-116 b are held in place byfasteners 706, such as nuts with spring steel washers, and thefasteners 706 are cosmetically disguised bycaps 708. As an alternative, thepivot housings 723 may be implemented by other arrangements such as bearings, bushings, axles, etc. Furthermore, instead of permitting free rotation of the ear cups 116 a-116 b about theirrespective studs 704, thepivot housings 723 and/orstuds 704 may be defined to provide rotation under friction, ratcheting movement, detent holding ear cups in position until forcibly overcome, etc. - Each
inner shell 712 further includes atab 720 designed to interact with a correspondingengaging feature 118 of theframe 408, which is most clearly shown inFIGS. 1, 2 , and 4A. In this example, the point of rotation of the ear cups 116 a-116 b is defined relative theframe 408 so that increasing movement of the ear cups 116 a-116 b into their stowed position places thetabs 720 into increasingly firm contact with their respective engaging features 118. This holds the ear cups 116 a-116 b firmly in place by friction between thetabs 720 and engagingfeatures 118. Further force applied to the ear cups 116 a-116 b in this direction more firmly engages the ear cups with the frame. Alternatively, thehelmet 100 may employ other means to hold the ear cups 116 a-116 b in place, such as springs, snaps, hooks, clips, magnets, etc. - The
foam 714 comprises acoustically absorbent material such as that typically used in conventional and industrial headsets. Theouter shell 716 includes aspeaker assembly 718 electrically coupled to theconnector 112. One example of the speakers is a circumaural type speaker. - Eve Shield and Guide
-
FIG. 8A-8B highlight theguide 402 andeye shield 107, respectively. In one embodiment, theshield 107 is made of a clear or intentionally tinted material that meets or exceeds OSHA, UL, and/or CSA requirements for safety glasses. For example, theshield 107 may be made of polycarbonate, acrylic, or another suitable material. Theguide 402 is made of a material suitable to provide self-lubrication e.g. nylons and others. - Although the
shield 107 and guide 402 are shown separately, the shield rides in a path defined and limited by theguide 402. When coupled to theguide 402, theshield 107 is slidable in generally upward and downward movements, allowing the wearer to retract and extend the shield (respectively). - The
shield 107 includes a number of features that help establish and limit its position with respect to the rest of thehelmet 100. In this respect, theshield 107 includes down catches 810. Eachcatch 810 includes a protrusion that engages a corresponding feature of theguide 402 to stop extension of theshield 107. Positioningnotches 812 are defined in theshield 812 to engage a corresponding pawl of theguide 402 and thereby hold theshield 107 one of these positions under adjustment by the wearer.Channels 814 defined in theshield 107 engage corresponding features of theguide 402 to help stop retraction of theshield 107. - The
guide 402 includesfoldover flaps 808 definingslide slots 809 that receive and accommodate theshield 107. Up-stops 802 stop retraction of theshield 107 by engaging thechannels 814. Thestops 802 include protrusions that are biased toward theshield 107 by their size, position, and the natural springiness of theguide 402 material.Pedestals 804 are provided for mounting of theguide 402 to theframe 408 by barbed studs, fasteners, clips, glue, press fit, screws, rivets, detent or other shape fit, etc. Apawl 806 engages with thepositioning notches 812 to hold theshield 107 in place, or releasably permit the extension or retraction of theshield 107 when the wearer applies sufficient force to slide theshield 107 and thereby disengage and reengage thepawl 806 from thenotches 812 one at a time.Notches 807 are engaged by the down catches 810 to stop extension of theshield 107. Alternatively, thenotches 807 may be omitted, with the upper edge of theguide 402 serving to engage the down catches 810, albeit at an earlier point than thenotches 807 would, and thereby not permitting as much down travel. - Rear Panel & Lens
-
FIG. 9 shows therear shell 110 andlens 114 in greater detail. In the rear shell, anotch 902 is defined to accommodate theconnector 112, which is attached to theframe 408 as shown above.Aligners 910 permit theshell 110 to be accurately positioned with respect to theframe 408. As shown, each of thealigners 910 is a base with a hole defined therein. Mounting to theframe 408 occurs by the aligner hole's receipt of a screw, rivet, barbed stud, or other fastener. Alternatively, another means of securing may be used such as glue, ultrasonic bonding, clips, etc. - The
shell 110 bears attachment pegs 904 shaped to engage corresponding holes 906 in therear lens 114 and thereby secure the lens relative to theshell 110. Theshell 110 andlens 114 may be attached by a press fit between thepegs 904 and holes 906 and/or additional means such as ultrasonic welding, solvent bond, epoxy, etc. Along these lines, thelens 114 includesknobs 908 to affix thelens 114 with respect to theframe 408. - A number of rear-facing light sources (not shown) may be attached to the
frame 408 at a suitable position to be aligned with thelens 114. For example, four LEDs of type T1 may be used. Or, instead of multiple light sources, a single light may be used with beam splitters, lenses, or other modification. These light sources serve a safety function, to make the wearer more visible to people behind him/her. Optionally, the rear-facing light sources may be red in color, or use a blinking pattern. The light sources receive power from theelectronics module 406 via one or more wiring harnesses, electrical buses, PCB traces, wires, Bluetooth or other wireless links, etc. - As an alternative to the
rear shell 110 andlens 114 that are separate from theupper shell 105 as illustrated, these features may be integral with theupper shell 105, thereby forming a larger, contiguous combined upper/rear shell. - Electronics Module
-
FIG. 10 shows theelectronics module 406 in greater detail. As mentioned above, theelectronics module 406 includes a source of light that projects through thefront lens 108 when themodule 406 is mounted to theframe 408. In one example, themodule 406 may be mounted to theframe 408 by fasteners, clips, glue, press fit, screws, rivets, detent or other shape fit, etc. In thefinished helmet 100, themodule 406 andlens 108 are built into thevisor 106 ofFIG. 1 . - One example of the
module 406 includes an array ofLEDs 1002 mounted to a printedcircuit board 1003. In the illustrated example, six white LEDs of type T1-3/4 may be used. TheLEDs 1002 may be aimed in the same direction (as shown), or at various angles to enhance the overall presentation of light around the wearer's workspace. Optionally, theLEDs 1002 may even be distributed to provide peripheral lighting in addition to straight-ahead illumination respective to the wearer's face and normal field of view. Instead of multiple separate beams (as shown), the same or similar effect may be accomplished with beam splitters, lenses, etc. - The
module 406 may include further electronics. In one example, themodule 406 includesbrow microphones 1004 enabling the wearer of thehelmet 100 to conduct hands free communications utilizing an off-helmet audio module coupled to theconnector 112. As an example, 6 mm directional microphones may be used to effectively define a “beam” of heightened sound reception aimed at the site of an average wearer's mouth. Themicrophones 1004 may include a moisture barrier, such as GORE-TEX® or a similar material. - As shown, the
module 406 also includes aphoto sensor 1008, such as a Perkin Elmer part A9060. Optionally, circuitry of theboard 1003 may automatically activate theLEDs 1002 and/or the rear light when thesensor 1008 finds that ambient light is less than a given threshold. - In order to provide more intelligent functionality to the
helmet 100, themodule 406 may also accommodate various circuitry in the form of discrete circuit elements, integrated circuits, ASICs, and the like. For example, themodule 406 may include Fortemedia brand FM1072LP chips in order to aid processing of audio signals received at themicrophones 1004, prevent feedback between the microphone and speakers, etc. As a further example, themodule 406 may include circuitry to convert mobile phone signals to a speakerphone and headset function for send and receive, and to provide a stereo amplifier for thespeakers 718. - The
module 406 further includes hand-operateddual switches 1006, such as E-Switch part EG2305A. Thedual switches 1006 may be attached to permit the wearer to selectively deactivate theLEDs 1002, rear light,microphones 1004, and/or other electronic equipment. - Optionally, through the
switches 1006 or on-board circuitry, themodule 406 may automatically or manually adjust the volume of the ear cup speakers. For instance, themodule 406 may utilize a softer volume while the ear cups are extended, and use a louder “speakerphone” volume while the ear cups are retracted. As a more particular example of the automatic embodiment, the ear cups 116 a-116 b may actuate a switch mounted to theframe 408 or other structure, where this switch is activated by a raised feature of one or both ear cups 116 a-116 b close to the pivot point when ear cups are extended. Without any intended limitation, some specific examples of this raised feature include one or both of the tabs 730-731 (FIG. 7 ). In this example, the switch is de-activated when the ear cups are retracted, and activated when the ear cups are extended. In one example, the switch connects the speakers to different amplifier circuitry depending upon whether the switch is activated or deactivated. In another example, the switch provides an input signal to a controller of theelectronics module 406, which regulates volume accordingly. - Helmet Features
- As described above, the
helmet 100 offers a variety of useful features in one package. Thehelmet 100 provides MP3, CD player, radio, cell phone, two-way radio, or other audio to the wearer by virtue of thespeaker assemblies 718 in ear cups 116 a-116 b. And, with thedirectional brow microphones 1004, thehelmet 100 enables the wearer to conduct mobile, hands free speech through an attached, off-helmet wireless phone or two-way radio transceiver. Audio signals are conveyed to/from remote electronics by theconnector 112 and appropriate cabling (not shown). Moreover, the wearer's eyes are protected by theretractable eye shield 107. To fully illuminate the wearer's workspace with minimal intrusion, the front-facinglight assembly 1002 is provided internal to thevisor 106 and protected by abrow lens 108 that is flush with thevisor 106. For added safety, the rear-facing light makes sure that the helmet is visible from behind. Furthermore, the ear cups 116 a-116 b are particularly convenient because they are retractable. Moreover, they are unlikely to catch on wiring, insulation, vehicle interior, brush, or other features of the wearer's work environment, since the ear cups 116 a-116 b when retracted are flush with helmet's exterior surface, namely, theupper shell 105 and therear shell 110. Despite the collective benefit of these features, the helmet still provides significant utility if one or more of these are omitted. - Helmet Operation
- In preparation for use of the
helmet 100, the wearer uses themechanism 614 to adjust theheadband base 602. The wearer also couples theconnector 112 to the desired electrical equipment, such as one-way or two-way audio equipment, battery pack, etc. When the wearer dons thehelmet 100, theaxis 722/120 is generally just above the wearer's ears. Thus, the ear cups 116 a-116 b when retracted rest above and generally behind the wearer's ears, flush with the outer surface of theshells tab 720 of theheadset assembly 430 and theengaging feature 118 of theframe 408. In this position, recognizing that the ear cups are stowed, thehelmet 100 may automatically provide an increased “speaker phone” volume to the ear cup speakers. - When the
helmet 100 is being worn, the wearer operates theswitches 1006 to configure electrical features such as the front lights, rear lights, audio on/off, microphone mute, and the like. To extend the ear cups 116 a-116 b, the wearer applies downward force to the ear cups 116 a-116 b, which disengages thetabs 720 from the engaging features 118. The ear cups 116 a-116 b then hang in a free pivoting mode, or they may be held in place by a feature (not shown) such as a catch, detent, ratchet, clasp, etc. In this position, recognizing that the ear cups are extended, thehelmet 100 may automatically select a decreased volume for ear cup speakers. - To retract the ear cups 116 a-116 b again, the wearer pivots the ear cups rearward, ultimately engaging the
tabs 720 with thefeatures 118. Greater force applied to the ear cups in this way more snugly engages them with theframe 408 in tighter fit. - While the foregoing disclosure shows a number of illustrative embodiments, it will be apparent to those skilled in the art that various changes and modifications can be made herein without departing from the scope of the invention as defined by the appended claims.
