Definitions
- This invention relates to an ear protector for a helmet, a helmet and a method for protecting the ears.
- detachable ear protection, or ear flaps, for lightweight sports helmets with head-shells cut above the ears is not new; particularly for snow sports, where ear protection is a feature of many designs of helmets currently available on the market.
- the purpose of fitting a lightweight helmet with detachable ear flaps has primarily been to give the wearer of the helmet the option to choose between whether they wish to cover the ears for protection from the elements, or not.
- Perforations or simple vents, are sometimes added to such prior art ear flaps in order to allow for improved hearing when worn.
- Known designs are made from flexible materials or foams and are usually attached to the helmet by means of press studs, or clips, forming an extension of the helmet liner.
- the ear flaps are usually positioned on the inside of, and operate independently from, the helmet chinstrap, although they may share the same connection points and utilise the same components for attachment.
- Ear flaps currently used on lightweight helmets have functional limitations because of their soft, flexible, structure. They are also known to have fitting and stability problems that can compromise the level of protection and comfort they provide to the ears. Some can press against the ears to the extent that they are uncomfortable and restrict hearing. Often they are prone to disconnect or detach too easily, shifting or falling off the helmet completely, exposing the ears and side of the face.

Description
- This invention relates to an ear protector for a helmet, a helmet and a method for protecting the ears.
- Throughout the specification, unless the context requires otherwise, the word “comprise” or variations such as “comprises” or “comprising”, will be understood to imply the inclusion of a stated integer or group of integers but not the exclusion of any other integer or group of integers.
- The concept of detachable ear protection, or ear flaps, for lightweight sports helmets with head-shells cut above the ears is not new; particularly for snow sports, where ear protection is a feature of many designs of helmets currently available on the market.
- The purpose of fitting a lightweight helmet with detachable ear flaps has primarily been to give the wearer of the helmet the option to choose between whether they wish to cover the ears for protection from the elements, or not.
- Perforations, or simple vents, are sometimes added to such prior art ear flaps in order to allow for improved hearing when worn. Known designs are made from flexible materials or foams and are usually attached to the helmet by means of press studs, or clips, forming an extension of the helmet liner. The ear flaps are usually positioned on the inside of, and operate independently from, the helmet chinstrap, although they may share the same connection points and utilise the same components for attachment.
- Ear flaps currently used on lightweight helmets have functional limitations because of their soft, flexible, structure. They are also known to have fitting and stability problems that can compromise the level of protection and comfort they provide to the ears. Some can press against the ears to the extent that they are uncomfortable and restrict hearing. Often they are prone to disconnect or detach too easily, shifting or falling off the helmet completely, exposing the ears and side of the face.
- For some time now, communications and visual devices have been attached by rudimentary means to helmets. Safety rescue, water patrol, sporting and other industries have identified the need for better methods of attaching these devices, without the requirement to modify the helmet, thereby enabling easier and more efficient utilisation of the latest technological developments. Ear flaps made of soft foam or similar material are limited in their application as a suitable platform for supporting communications and visual devices and are not currently designed to facilitate this need.
- It is an object of this invention to overcome or at least mitigate some of the problems identified in the background art with respect to previous designs of ear flaps.
- In accordance with one aspect of the present invention, there is provided a detachable ear protector for attachment to a helmet having a chin strap, comprising:
- a support member shaped to cover an ear of a wearer of the helmet when attached thereto;
- a rigid protective outer cover formed of material resistant to high impact and integrally formed with said support member to provide a high impact protective region covering a major portion of the support member on the outer side thereof; and
- an inner pocket formed of resilient ear contacting material attached to the inner periphery of said support member defining an inner recess to proximately accommodate the pinna of the wearer's ear within the pocket;
- said pocket being partly attached to the side edges of said support member to define a pair of openings, one opening being disposed at the bottom of said support member and another opening being disposed at the top of said support member;
- wherein said openings are sized to pass the chin strap therethrough so that the ear protector is positively engaged by the chin strap against the side of the head and covering the ear of the wearer, when fitted thereon.
- Preferably, said support member and said outer cover are formed with juxtaposed central apertures to overlie the ear canal of the wearer; said outer cover having a rigid boss circumscribing and interconnecting said central apertures; and said boss being formed with a retentioning means to retain a central ear covering member.
- Preferably, said ear covering member comprises a rotatable closure to selectively open and close a passage through said central apertures to facilitate hearing or access to the wearer's ear.
- Preferably, said ear covering member comprises a housing for locating a loudspeaker of an audio system within said central apertures.
- Preferably, said outer cover is formed with an outwardly projecting locating member along the top thereof, said locating member being shaped to fit within a receiving slot formed within said helmet, so that when said locating member is received therein, the ear protector is correctly aligned with the helmet.
- Preferably, the top of the ear protector is convexly configured of complementary shape to a concave recess provided along the edge of the helmet proximate to the location of a wearer's ear, when correctly worn by the wearer, so that the ear protector becomes contiguous with the helmet when positively retained by the chin strap of the helmet.
- Preferably, the having a triangular divided chin strap with a buckle divider
- In accordance with another aspect of the present invention, there is provided a helmet having an outer protective high impact resistant shell and a resilient inner liner for accommodating the head of a wearer, the helmet comprising:
- a chin strap; and
- a pair of ear protectors, each ear protector being of the type as claimed in any one of claims 1 to 6.
- Preferably, said chin strap is divided triangularly at either side with a divider buckle to attach the chin strap at two discrete attachment points to the helmet shell, one forward and the other rear, of the proximate location of the ear of a wearer when the helmet is worn, at either side of the helmet.
- In accordance with a further aspect of the present invention, there is provided a method for covering the ears of a wearer of a helmet have a lower edge cut above the ears, comprising:
- covering the ears with ear protectors fixed to the chin strap of the helmet; and
- positively locating the ear protectors in an adjacent and juxtaposed relationship with the lower edge of the helmet directly above the ears, contiguous with the shell of the helmet.

Onehelmet attaching portion 31 a of a helmet attaching strap is anchored forward of theconcave recess 19, and the otherhelmet attaching portion 31 b is anchored rearward of the concave recess in this manner, the straps may repose about the head of a wearer, either side of where the wearer's ear would be located for comfortable and positive retention of the helmet to the wearer's head when thebuckle 27 is fastened. - The
ear protector 13 comprises asupport member 35, a rigid protectiveouter cover 37 and aninner pocket 39. - The
support member 35 andpocket 39 are formed of similar material to theliner 17, and theouter cover 37 is formed of similar material to theshell 15. - The
support member 35 is shaped to completely cover the ear of a wearer when fitted to the helmet and forms a base to which theouter cover 37 and thepocket 39 are attached. The top of thesupport member 35 is convexly contoured to complement the shape of theconcave recess 19 and move hingedly laterally of the helmet, relative to theshell 15. Thesupport member 35 is also formed with a central aperture to overlie the ear canal of the wearer, when operatively positioned with respect to the shell. - The
outer cover 37 is an annular dome shape, the radius of the outer circumference thereof describing an upper arcuate portion of marginally larger radius than the top of thesupport member 35, and a lower arcuate portion of marginally smaller radius than the corresponding bottom of the support member. Theouter cover 37 is similarly provided with a central aperture concentric and juxtaposed with the central aperture of thesupport member 35 to maintain the opening through the ear protector to the ear of the wearer. - A
rigid boss 41 comprising a radial, outer flange 41 a and an axial spigot portion 41 b circumscribes the central apertures of thesupport member 35 andouter cover 37 and keys with the inner periphery 43 of the central aperture of the outer cover to pinch the support member in juxtaposed relationship with theouter cover 37. As shown, the outer flange 41 a is disposed on the inner side of thesupport member 35, and the spigot portion 41 b is formed with external locating lugs 45 to frictionally engage corresponding locating grooves 47 provided on the inner periphery 43 of theouter cover 37. - A central
ear covering member 49 of corresponding size and shape to the central aperture of theboss 41 is provided with a series of protruding lockingfingers 51 to mate with a series of lockinggrooves 53 formed within the inner circumference of the boss. Thefingers 51 and lockinggrooves 53 form corresponding parts of a retentioning means to fixedly situate the coveringmember 49 within the central aperture of theboss 41. Moreover, the coveringmember 49 is fitted to the outside of theouter cover 37 and the lockingfingers 51 engaged with the lockinggrooves 53. The coveringmember 49 is then rotated clockwise into a locked position where thefingers 51 are retained within recesses 53 a formed within each lockinggroove 53, holding thesupport member 35 and theouter cover 37 firmly together. - The covering
member 49 in the present embodiment is provided with a pair of diametrally opposed vents 55 and arotatable closure 57 formed withcorresponding holes 59. Theclosure 57 is pinned to the centre of the covering member and is adapted to rotate between an open position where thevents 55 and theholes 59 are aligned to allow access through the central apertures, and a closed position where the vents and the holes are closed by the radially intervening portions of the coveringmember 49 and theclosure 57 obscuring theholes 59 and vents 55, respectively. - The
pocket 39 is attached to the outer periphery of thesupport member 35, on the inner side thereof. A largeinner recess 61 is centrally formed within thepocket 39 to proximately accommodate the pinna of the wearer's ear within the pocket when the ear protector is operatively positioned with respect to theshell 15 and expose the central aperture of theboss 41 on the inner side of the ear protector. Thepocket 39 is attached to the side edges of thesupport member 35 and a portion of the bottom edge thereof, so that a comparatively small opening in the form of aslot 63 is provided at the bottom of the ear protector and amajor opening 65 along the top, between thesupport member 35 and thepocket 39. Theslot 63 is sufficiently large to allow thebuckle 27 and thedivider 29 of a chin strap to pass therethrough. - The pocket forms a thickened
U-shaped portion 67 to circumscribe the sides and bottom of theinner recess 61, and a thinarcuate web 69 recessed itself to similarly circumscribe the top of theinner recess 61, but also accommodate the top of the pinna of a helmet wearer that may protrude beyond theinner recess 61. - The top of the
outer cover 37 is formed with an outwardly projecting locatingtab 71 integral therewith. The locatingtab 71 is shaped to fit within a receiving slot (not shown) formed between theinner liner 17 and theshell 15 of the helmet, at the apex of theconcave recess 19. The distal end of the locatingtab 71 is formed with aspigot 73 to sit within a complementary shaped well within the receiving slot, so that when said locating member is received therein, theear protector 13 is correctly aligned and hingedly retained with respect to the helmet. - Now describing the manner of operatively locating each
ear protector 13 relative to thehelmet 11, reference will be made toFIGS. 10A to 10C,FIGS. 11A to 11E andFIG. 12 . - As shown in
FIGS. 10A and 11A , theear protector 13 is initially located so that the top of thereof is adjacent to the buckle end of the particular strap half to which the ear protector is to be fitted. Obviously, the inner side and outer side of the ear protector is relatively disposed to adopt the corresponding inner and outer sides of the helmet at the particular side of the helmet to which the protector is being fitted. - The
buckle 27 is then pushed through themajor opening 65 into the inside of thepocket 39 as shown inFIG. 10B and then is worked through theslot 63 as shown inFIGS. 11B and 11C . Thedivider 29 follows thebuckle 27 and is similarly passed through themajor opening 65 and eventually theslot 63 to project therefrom at the bottom of the ear protector, as shown inFIGS. 10C, 11D and 11E. As thedivider 29 is passed through the slot, the locatingtab 71 is inserted into the receiving slot therefor within the helmet and thespigot 73 seated within the well. At this position, the top of theouter cover 37 is seated snugly within theconcave recess 19 to be contiguous with the contour of theshell 15. - Importantly, each ear protector is sized and each
divider 29 is located distally from the shell a distance commensurate to the axial extent of theear protector 13, between the top and bottom thereof. Furthermore, thedivider 29 is formed so that the upper edge thereof can accommodate the adjoining portion of the bottom of thesupport member 35 between it and the corresponding helmet attaching straps, as shown in theFIG. 12 . In this manner, when theear protector 13 is located in an operative position, it is retained snugly between the corresponding divider and adjacent concave recess of the shell and is integrally formed with the helmet attaching straps to be positively retained in position thereby. - The second embodiment is substantially similar to the first embodiment, except that the central
ear covering member 49 accommodates a speaker housing for an audio system instead of vents. In describing the second embodiment, the same base reference numerals will be used for like components previously described in the first embodiment, except that all reference numerals will be designated with ′. - As shown in
FIG. 13 of the drawings, the coveringmember 49′ incorporates a waterproof loudspeaker housing 101′ formed of pliable material, within which a loudspeaker (not shown) is disposed. - The
housing 101′ is formed with corresponding lockingfingers 51′ to engage the lockinggrooves 53′ provided in the central aperture of theboss 41′ and be rotated into locked position within the recesses 53 a′. Accordingly, thespeaker housing 101′ is fixedly attached to theear protector 13′ in corresponding manner to the vents of the first embodiment. The loudspeaker therein can be connected by wire or wireless means to an audio receiver or player located on the rear of the helmet or elsewhere on the person of the wearer to deliver audio signals via the loudspeaker to the wearer. - This particular embodiment is ideal for providing a two-way communication system with appropriate location of a microphone on the helmet.
- It should be appreciated that both embodiments incorporate features that overcome the limitations of current helmet ear flaps. When the ear protectors are fitted to a lightweight helmet, the combination provides a more versatile helmet that is suitable for a wider range of sport and industrial applications because the ear protectors are designed to perform as an extension of the helmet shell. The ear protectors not only protect the ears, but also provide a stable support member that permits the attachment of communication systems and other devices in proximity to the ears of a wearer.
- In the case of communication systems, these have previously only be achievable with the addition of bulky headsets or similar apparatus. The present embodiments offer a method of attachment and a speaker housing that retains a compact, close fitting helmet profile.
- The rigid plastic outer cover of the ear protector provides an increased level of safety protection to the ears, when compared to helmet flaps made from softer materials. A soft foam lining fitted to the outer cover to form a generous ear pocket achieves a superior, more comfortable fit, which is further enhanced by the hinging effect at the join between the ear protector and the mating helmet contours, providing better accommodation of varying head shapes than a full helmet shell with ear coverage. The enclosure of the upper portion of the chin strap inside the ear protector and the locating tab provided on the outer cover, ensures that the entire unit remains stable and secure when positioned over the ears.
- The provision of the audio vent system of the first embodiment, permits adjustment between a closed position where the elements (wind, water, cold) may be shut out from direct contact with the ears, and a fully opened position allowing increased audibility to the wearer's surroundings.
- The retentioning system used for the ear covering member provides means for the attachment of not only a variety of different communications and music devices, but also a connection facility for altimeters, cameras and the like.
- The attachment of the ear protector and audio system results in a complete head protection unit that has the stability and performance benefits of full shell helmet coverage. Furthermore, the advantages of easy detachment to a helmet designed with a cut above the ears allows tremendous flexibility in helmet use, maintaining comfort features to suit a variety of different environments.
- It should be appreciated that the scope of the present invention is not limited to the particular embodiments described herein.
