It is to be expressly understood that the description and drawings are only for the purpose of illustration and are an aid for understanding. They are not intended ~ 5 to be a definition of the limits of the invention.
Detailed description of preferred embodiments Shown in Figures 1 to 8 is a sporting helmet 20 according to a preferred embodiment 20 of the present invention. On these figures, sporting helmet 20 is a hockey helmet.
Helmet 20 is made up of a front shell 22 and a back shell 24 interconnected together and adapted to move in relation to each other, and two locking device 48 located on each side of helmet 20 just above the ears of the player. Front shell 22 and back shell ,a 24 are preferably made of a relatively rigid material, such as a polycarbonate material, a rigid thermoplastic, or a thermosetting resin in order to provide a strong helmet that will protect the head of the player.
Front shell 22 includes a plurality of ventilation apertures 26 located at various positions. While ventilation apertures 26 are not essential to the present invention, they do provide the added comfort of allowing air to circulate around the head of the player, thus permitting perspiration to evaporate.
1o The inner surfaces of front shell 22 and back shell 24 are covered with front and rear inner pads 28 and 30 respectively. More preferably, both front and rear pads 28, 30 entirely cover inner surfaces of front shell 22, 24. Front and rear pads 28, 30 are preferably made of expanded polypropylene (EPP). Rear pad 30 comprises a top portion 30T extending over the head of the player. The inner surface of front pad 28 is covered with a front comfort pad 32 and the inner surface of rear pad 30 is covered with a rear comfort pad 34 and a top comfort pad 36. Front comfort pad 32 and rear and top comfort pads 34, 36 may or not entirely cover inner surfaces of front and rear pads 28, 30 respectively. Rear comfort pad 34 comprises an occipital portion 340C, a left side portion 34LS and a right side portion 34RS (see Fig. 5).
Helmet 20 also comprises two downwardly extending sides 38 that extend along the sides of the face of the player in front of the ears of the player. Sides 38 provide additional protection to the sides of the head of the player, and further provide a useful location for connecting ear loops 40. At the base of sides 38 are apertures 42 , ~ 85493-427-CANADA
(only the left side shows apertures 42) through which ear loops 40 is looped.
The other end of ear loops 40 is looped into one of apertures 44 located on the base of rear shell 24. A chinstrap 46 is adapted to be attached to each of ear loops 40, so that when it is secured beneath the chin of the player, helmet 20 is securely fastened onto the head of the player.
Helmet 20 comprises locking mechanisms 48 each having a door 50, springs 52, an actuator 53 and a base 54. Overlapping portions of front and rear shell 22 and 24 are confined between actuator 53 and base 54. These overlapping portions may comprise 1o a plurality of engaging members that will allow front shell 22 to be secured to rear shell 24 in a selected position. In the locking position the cooperation between actuator 53 and base 54 exerts a compressive force on the engaging members of front shell 22 and rear shell 24, so that they interact with one another to secure the front and rear shells 22, 24 in a selected position.
In operation, a player who puts on helmet 20 and realizes that it is too large or too small, does not need to remove helmet 20. The player must simply reach up and pull upwards so that locking device 48 moves into the release position. Once locking device 48 is in the release position, the player can expand or contract the size of 2o helmet 20 by pushing or pulling front and rear shells 22, 24 in relation to each other.
Helmet 20 may comprise ear covers 56 for protecting the ears of the player.
It is understood that helmet 20 may comprise a sole shell having front and rear portions, a sole inner pad having front and rear portion covering the inner surface of the sole shell and a sole comfort pad covering the inner surface of the inner pad. It is also understood that helmet 20 may comprise front and rear shells that are not adjustable one relative to the other.
Helmet 20 further comprises an inflatable bladder 58 mounted between rear comfort pad 34 and rear pad 30. Inflatable bladder 58 comprises an occipital chamber in fluid communication with left and right side chambers 58LS, 58RS through respective left and right air channels 60L, 60R. A pump 62 is connected to inflatable bladder 58, pump 62 being in fluid communication with occipital chamber 580C
1o through a tube 64. It is understood that pump 62 may be connected to left or right side chambers 58LS, 58RS. A one way valve (not illustrated) is mounted within tube 64. Pump 62 comprises a dome 66 and a base 68 having an aperture 70 communicating with tube 64, dome 66 being sealed to the base 68. Apex portion of dome 66 comprises an aperture through which air may pass. Inflatable bladder also comprises a release valve 72 mounted on occipital chamber 580C for deflating inflatable bladder 58. Again, it is understood that release valve 72 may be mounted on left or right side chambers 58 LS, RS. A pump cover 74 protects dome 66 and release valve 72.
As shown on Figures 7 and 8, the head of the player comprises a crown region CR, left and right temple regions LT, RT, left and right side regions LS, RS and an occipital region OC. Left and right side regions LS, RS are approximately located above the ears of the player. Occipital region OC substantially corresponds to the region under the occipital protuberance of the head.
' 85493-427-CANADA
In operation, upon depression of dome 66, air located within dome 66 passes through tube 64 and reaches occipital chamber 580C, and eventually, left and right side chambers 58LS, 58RS. When dome 66 return to its natural form, air is again admitted in dome 66. Occipital and left and right side chambers 580C, 58LS, 58RS can therefore be filled to the desired volume of air by repeatedly depressing dome 66.
Pump 62 is thus actuatable by the player when he/she repeatedly depresses dome 66.
Pump cover 74 is sufficiently flexible to allow the player to depress dome 66 and release valve 72. More particularly, pump cover 74 may comprise grooves for allowing the player to depress the portions of pump cover 74 located over dome to and release valve 72 respectively, or the portions of pump cover 74 that cover dome 66 and release valve ?2 respectively may have a thinner thickness.
When inflated, inflatable bladder 58 applies pressure upon occipital region OC
and left and right side regions LS, RS of the head of the player in order to have a close fit between the head and the helmet. More particularly, contact of inflatable bladder 58 with occipital region OC tends to urge the interior of helmet 20 closer to the head. In fact, left and right side chambers 58LS, RS allow a better lateral fit while occipital chamber 580C allows a better longitudinal fit. Hence, pump 62 is actuable by the player for inflating inflatable bladder 58 such that occipital chamber 580C
and left 2o and right side chambers 58LS, 58RS apply pressure upon occipital region OC
and left and right side regions LS, RS of the head, thereby bringing the inner surfaces of helmet 20 closer to the head. If necessary, the player can deflate inflatable bladder 58 by depressing release valve 72.
Inflatable bladder 58 is not confined within a pad or liner and is thus free to expand and the air path is not therefore compromised. Gaps between occipital region OC and left and right side regions LS, RS and the interior of helmet 20 may be filled by inflatable bladder 58 as desired by the player. Refernng to Figure 6, inflatable bladder 58 comprises several apertures 76 for affixing inflatable bladder 58 to the outer surface of rear comfort pad 34. Inflatable bladder 58 is thus mounted between rear comfort pad 34 and rear pad 30 and can expand therebetween in order to apply pressure upon occipital region OC and left and right side regions LS, RS. It is understood that inflatable bladder 58 may also be affixed to rear pad 30. It is also 1o understood that different affixing means may be used to affixed inflatable bladder 58 to rear comfort pad 34 or rear pad 30. It is further understood that inflatable may only comprise an occipital chamber in fluid communication with a pump. Lastly, it is understood that the inflatable bladder may be affixed to the inner pad covering the interior surface of the shell of the helmet, the inflatable bladder contacting the occipital region of the head, or it can be mounted between the shell and the inner pad.
The above description of preferred embodiments should not be interpreted in a limiting manner since other variations, modifications and refinements are possible within the spirit and scope of the present invention. The scope of the invention is 2o defined in the appended claims and their equivalents.

A pump 62 is connected to inflatable bladder 58, pump 62 being in fluid communication with occipital chamber 580C
1o through a tube 64. It is understood that pump 62 may be connected to left or right side chambers 58LS, 58RS. A one way valve (not illustrated) is mounted within tube 64. Pump 62 comprises a dome 66 and a base 68 having an aperture 70 communicating with tube 64, dome 66 being sealed to the base 68. Apex portion of dome 66 comprises an aperture through which air may pass. Inflatable bladder also comprises a release valve 72 mounted on occipital chamber 580C for deflating inflatable bladder 58. Again, it is understood that release valve 72 may be mounted on left or right side chambers 58 LS, RS. A pump cover 74 protects dome 66 and release valve 72.
As shown on Figures 7 and 8, the head of the player comprises a crown region CR, left and right temple regions LT, RT, left and right side regions LS, RS and an occipital region OC. Left and right side regions LS, RS are approximately located above the ears of the player. Occipital region OC substantially corresponds to the region under the occipital protuberance of the head.
' 85493-427-CANADA
In operation, upon depression of dome 66, air located within dome 66 passes through tube 64 and reaches occipital chamber 580C, and eventually, left and right side chambers 58LS, 58RS. When dome 66 return to its natural form, air is again admitted in dome 66. Occipital and left and right side chambers 580C, 58LS, 58RS can therefore be filled to the desired volume of air by repeatedly depressing dome 66.
Pump 62 is thus actuatable by the player when he/she repeatedly depresses dome 66.
Pump cover 74 is sufficiently flexible to allow the player to depress dome 66 and release valve 72. More particularly, pump cover 74 may comprise grooves for allowing the player to depress the portions of pump cover 74 located over dome to and release valve 72 respectively, or the portions of pump cover 74 that cover dome 66 and release valve ?2 respectively may have a thinner thickness.
When inflated, inflatable bladder 58 applies pressure upon occipital region OC
and left and right side regions LS, RS of the head of the player in order to have a close fit between the head and the helmet. More particularly, contact of inflatable bladder 58 with occipital region OC tends to urge the interior of helmet 20 closer to the head. In fact, left and right side chambers 58LS, RS allow a better lateral fit while occipital chamber 580C allows a better longitudinal fit. Hence, pump 62 is actuable by the player for inflating inflatable bladder 58 such that occipital chamber 580C
and left 2o and right side chambers 58LS, 58RS apply pressure upon occipital region OC
and left and right side regions LS, RS of the head, thereby bringing the inner surfaces of helmet 20 closer to the head. If necessary, the player can deflate inflatable bladder 58 by depressing release valve 72.
Inflatable bladder 58 is not confined within a pad or liner and is thus free to expand and the air path is not therefore compromised. Gaps between occipital region OC and left and right side regions LS, RS and the interior of helmet 20 may be filled by inflatable bladder 58 as desired by the player. Refernng to Figure 6, inflatable bladder 58 comprises several apertures 76 for affixing inflatable bladder 58 to the outer surface of rear comfort pad 34. Inflatable bladder 58 is thus mounted between rear comfort pad 34 and rear pad 30 and can expand therebetween in order to apply pressure upon occipital region OC and left and right side regions LS, RS. It is understood that inflatable bladder 58 may also be affixed to rear pad 30. It is also 1o understood that different affixing means may be used to affixed inflatable bladder 58 to rear comfort pad 34 or rear pad 30. It is further understood that inflatable may only comprise an occipital chamber in fluid communication with a pump. Lastly, it is understood that the inflatable bladder may be affixed to the inner pad covering the interior surface of the shell of the helmet, the inflatable bladder contacting the occipital region of the head, or it can be mounted between the shell and the inner pad.
The above description of preferred embodiments should not be interpreted in a limiting manner since other variations, modifications and refinements are possible within the spirit and scope of the present invention. The scope of the invention is 2o defined in the appended claims and their equivalents.
