The present invention generally relates to helmet for motor vehicles and motorsports, particularly to an internal helmet padding for mounting onto an inner side of an impact absorbing liner in the helmet.
A safety helmet for riding a vehicle is constituted by fitting an impact absorbing liner comprising styrene foam or the like to an inner side of an outer shell and fixedly adhering an interior body (cushion pad) formed by covering a surface of a cushion material made of foamed urethane or the like by a cloth compatible with the skin at a predetermined portion on an inner side of the impact absorbing liner.
The interior body impact absorbing liner, is usually constituted by forming a core material of a rigid plate in a ring-like shape and by covering it with a cushion material which is itself covered by a cloth in those areas which are in direct contact with a human head.
The difference between a high quality helmet and a lower quality helmet often resides in the ability of the helmet to control visor or goggle fogging. Fogging is generally mitigated by controlling the air circulation within the helmet, particularly by creating a hermetic breath box. Known helmets often comprise breath guards to aid in limiting the user's breath vapor from flowing upwardly and reaching the helmet visor or goggles. Breath guards are useful but lack the ability to provide an adequate fit for several users in part due to the particular configuration of such users head, cheeks, nose and/or chin. Particularly, it has been found that breath vapor may flow between the breath guard and the inner liner about the user's cheeks (See element 320,
Even in the presence of a high quality helmet equipped with a good breath guard, it remains that breath vapor is still able to reach the helmet's visor or goggles. Some helmet have gone all the way to providing a sealed breath box where the user needs to wear an air mask for optimal breath control.
However, air masks are known to be of lower comfort to the user. Furthermore, not all users desire having an air mask on their face while wearing an helmet. There is thus a need for an helmet that has an improved breath box for breath control while limiting the need for the user to wear an air mask.
The shortcomings of the prior art are generally mitigated by providing a flexible cheek cushion between the helmet cushion pad or inner liner and the breath guard.
According to an aspect of the present invention, it is disclosed an air control pad for an helmet. The helmet for use with the air control pad generally comprises an outer shell, an inner liner, a substantially transparent face visor, a chin bar and a breath guard. The outer shell generally has an inside surface facing a head of a person when wearing the helmet. The inner liner generally surrounds the head of the user when wearing the helmet and is mounted to the helmet outer shell. The inner liner generally has an inner face forming a curved surface for receiving the head of the user when wearing the helmet. The face visor is preferably substantially transparent and attached to the helmet outer shell. The chin bar is disposed below the face visor. The chin bar generally has an inside surface facing toward the person when wearing the helmet. The breath guard generally extends from the inside surface of the chin bar toward the face of the user when wearing the helmet forming a breath guard face edge. The air control pad preferably is a flexible element extending upwardly and/or inwardly from the helmet inner liner on the right or left inner side of the face visor, the flexible element being configured to be in contact with the face edge of the breath guard and the inner liner.
According to an aspect of the present invention, there is disclosed an air control pad that is cushioned between an helmet breath guard, the helmet inner liner and the face of a user when wearing the helmet. The air control pad is preferably made from a flexible/deformable material capable of adapting to the shape of the user.
According to an aspect of the present invention, there is disclosed an air control pad made from polymeric materials.
According to an aspect of the present invention, the air control pad is configured to improved air control within the helmet breath box. The air control pad aims at reducing breath vapor flow from the helmet breath box to the goggles or face visor, thus preventing the formation of fogging. As such, the air control pad in combination with the helmet breath guard and inner liners aims at constraining the user's breath vapor in the helmet breath box.
According to an aspect of the present invention, there is disclosed a method of mitigating the presence of breath vapor flow from the breath box to the helmet visor or goggles. The method comprising the step of inserting an air control pad between the breath guard and inner liner while preferably maintaining contact with the user's face when wearing the helmet.

In the present embodiment, still referring to
According to an embodiment, in use, the air control pads 210, 220 are configured to be compressed between the face edge 150 of the breath guard 120 and the upper surface 122, 124 of the inner liner 108 and/or the face of the user when wearing the helmet 100 limiting the ability of breath vapor to reach the visor 106 and condense thereon.
According to an embodiment, the air control pads 210, 220 are used as a pair in an air control pad system 200. The air control pad system 200 generally comprises a pair of right and left control pads 210, 220 for mitigating the breath vapor flow to the visor 106 or goggles thus reducing the occurrences of fogging in the visor 106 or goggles. The right and left airs control pads 210, 220 are preferably located on the right and left sides of the helmet 100 about the inner liner 108 in proximity to the user's cheeks when wearing the helmet 100. According to the preferred embodiment, the right and left air control pads 210, 220 are generally respectively in contact with the user's right and left cheeks when wearing the helmet 100. In addition, the right and left air control pads 210, 220 are in contact with the helmet 100 breath guard 120. According to the preferred embodiment, the right and left air control pads 210, 220 are in contact with the breath guard's 120 face edge 150. Other embodiments of the air control pad system 200 for a helmet 100 may have the right and left control pads 210, 220 in contact with the underside 126, 128 of the helmet breath guard 120.
According to an embodiment, the surface of the left and right control pads 210, 220 which is in contact with the breath guard 120 cover around 30% of the total surface of the breath guard 120 defined as being the surface between the outer left side and the outer right side of the breath guard 120.
According to a preferred embodiment of the present invention, the air control pads 210, 220 are made from air tight fabric or material that once in contact with the user's face and the breath guard 120 seals the breath box and prevent breath vapor from flowing upward and reaching the visor 106. As such, in the preferred embodiment, the breath guard 120, the inner liner 108, the air control pads 210, 220 and the face of the user form an air tight barrier preventing the upward flow of air to the helmet 100 visor 106.
According to an embodiment, the air control pads 210, 220 are made from a deformable material covered by a flexible, yet preferably airtight covering material. Understandably, though preferred, air-tight covering fabric is not essential for the air control pad 210, 220. Other embodiments, could be designed with a material that allows air through in its inoperative state, uncompressed state, but once compressed by both the user face and the breath guard 120 face edge 150, the material is rendered dense enough to prevent the breath vapor from easily flowing through thus providing an adequate level of air blocking ability between the breath guard 120 and the user's face. Yet, the material or fabric used for making the air control pads 210, 220 should be adequate for skin contact and preferably temperature insensitive, at least for the portion of the air control pad that is designed to be in contact with the user's face. Understandably, the underside of the air control pad 210, 220, the portion that is designed to be in contact with the inner liner 108 may be made from other material as to permit adherence to the inner liner 108 when used or sold with or separately as add-ons to an existing helmet 100.
According to an embodiment, the air control pads 210, 220 may be designed to be attached to an existing helmet 100 post purchase. In such a retrofitting embodiment, the helmet 100 owner would preferably acquire air control pads 210, 220 having a quick attach securing element. The quick attach element may be any system that allows to retrofit the air control pads 210, 220 by securing them to the inner liner 108 of an existing helmet 100. A non-limitative example of quick attachment element is the use of Velcro™ elements on the air control pads 210, 220 and inner liner 108. The Velcro™ elements could be glued, stitched or otherwise attached to the inner liner 108 of the helmet 100 to complement the other the Velcro™ elements positioned on the underside of the air control pads 210, 220. As such, the underside of the air control pads 210, 220 could be provided with the hook anchoring element of Velcro™, while the inner liner 108 fabric could act with or without alteration as the softer complementary loop Velcro™ element thus providing the adequate adherence between the helmet inner liner 108 upper edge and the underside of the air control pads 210, 220.
According to an embodiment, the air control pads 210, 220 are provided as add-ons to existing helmets 100. The air control pads 210, 220 may thus be provided in distinct sizes to fit the various user face sizes and provide an alternative to users desiring the smaller possible air control pads 210, 220 while also obtaining the air control effect of the air control pads 210, 220.
According to an embodiment, depending on the size of the inner liner 108, the size of the air control pads 210 and 220 varies from 20% to 50% of the size of the inner liner 108.
According to an embodiment, there is disclosed an helmet 100 with air control pads 210, 220 mounted therein. The helmet 100 comprises air control pads 210, 220 mounted to or integral with the inner liner 108. The air control pads 210, 220 may be secured to the inner liner 108 by stitching, glue or via any other suitable means of mounting the air control to the inside of the helmet 100 while maintaining its air control ability.
According to yet another embodiment, the air control pads 210, 220 could be embodied as air pockets made from air tight fabric positioned about the upper edge of the inner liner 108. The air control pads 210, 220 according to this embodiment could be customized to the user's face configuration. Other configurations of the air control pads 210, 220 could have an integrated air pump system to fill the air pocket upon wearing the helmet 100. In such an embodiment, securing of the helmet 100 to the user head or lowering of the chin bar 104 could automatically actuate an air control pad system 200 in which air is pumped in the air control pads 210, 220 until adequate air control is obtained. The actuation of the air pump system could be automatic or manual. Therefore, some embodiments of the helmet 100 air control pad could have a manual pump for inflating the air pads until the user deems the helmet 100 adequately mitigates the breath vapor flow from the user's mouth and/or nose to the visor.
According to yet another embodiment, the air control pad 210, 220 could be made from mildly compressible, yet deformable material such as gel-like substances that generally occupy a defined volume but which may be displaced to take different form. In such an embodiment, the pressure of the user's face against the air control pads 210, 220 would deform the gel like air control pads 210, 220 to adapt them to the user's face, yet allow the air control pads 210, 220 gel to fill the otherwise unoccupied space between the breath guard 120 and inner liner 108.
According to another embodiment, the air control pad is configured to be inserted between the breath guard 120 and the inner liner 108 of an MX helmet. According to this embodiment, the air control pads are designed to control breath vapor from flowing upwardly and potentially generating fogging in the user's visor or goggles. The use of air control pads may also be desired in MX helmet to increasing the efficiency of an MX helmet breath box. According to an embodiment, the air control pads 210, 220 outer surface or at least the surface of the air control pads that is to be in contact with the face of the user when wearing the helmet 100 may be recovered with textile material. Covering the air control pads 210, 220 with textile may improve the user comfort when wearing the helmet 100.
According to another embodiment, the air control pads 210 and 220 may be integrated to the breath guard 120, such as but not limited to being mounted to the inside of the chin bar 104.
According to an embodiment of the present invention, a method of using the air control pads 210, 220 is disclosed. The method comprises the step of upwardly rotating the chin bar 104 to its secured non-operational position. The method further comprises the step of securing a right and a left air control pads 210, 220 to the right and left upper surface 122, 124 of the inner liner 108 about the portion in contact with the cheek of the user when wearing the helmet 100.
The method further comprising the step of downwardly rotating the chin bar 104 to its secured operational position (see
According to an embodiment, a method of controlling breath vapor flow to the visor is disclosed, the method comprising the step of inserting air control pads 210, 220 between inner liner 108 on the side facing the head of the user and the breath guard 120 so that it becomes compressed against the user's face when wearing the helmet 100.
