[0040]
[0041] As shown in the cross-sectional view of
[0042] Docking cage 112 may be made from a material different from the material of liner 110. Thus, liner 110 may be made from a softer material configured primarily to absorb forces while docking cage 112 may be made from a material suitable for coupling to chinbar 104. In certain embodiments, the material of docking cage 112 may also be configured to absorb forces and provide cushion to the user. Docking cage 112 may be formed separately from liner 110 and assembled to liner 110, or may be formed together (e.g., co-molded) with liner 110.
[0043] Docking cage 112 may be coupled to liner 110. Docking cage 112 may be cage shaped and, in certain embodiments, all or at least a portion of docking cage 112 may be disposed on the second side 202 of liner 110 (e.g., posts 116A and 116B may be disposed on the second side 202 of liner 110 and in certain such embodiments, other portions of docking cage 112 may be disposed within liner 110 or on the first side 200 between liner 110 and outer shell 108). Additionally, in certain embodiments, docking cage 112 may be coupled (e.g., attached via mechanical fasteners such as snaps, rivets, bolts, posts, and/or interference fits or with adhesives or other techniques) to liner 110, such as on the second side 202 of liner 110. Additionally or alternatively, docking cage 112 may be coupled to outer shell 108 and/or another portion of helmet 102. Accordingly, in certain embodiments, all or portions of docking cage 112 may be disposed on the first side 200 of liner 110, second side 202 of liner 110, or within liner 110. Such embodiments may position portions of chinbar 104 (e.g., portions of chinbar 104 configured to couple to docking cage 112) on the first side 200 and/or second side 202 of liner 110 when chinbar 104 is coupled to docking cage 112.
[0044] Certain features of docking cage 112 (e.g., posts) may protrude through liner 110 to interact with chinbar 104. Such posts may interact with chinbar 104 to, for example, control the spatial relationship (e.g., distance between) of docking cage 112 to chinbar 104 and/or hold chinbar 104 relative to docking cage 112 and also, in certain embodiments, control spatial relationship of docking cage 112 relative to liner 110 and/or hold liner 110 to docking cage 112. Thus, the spatial relationship of chinbar 104 to liner 110 may be better controlled, improving helmet fit and increasing wearer comfort.
[0045] Disposing at least a portion of docking cage 112 on the second side 202 may allow for an attachment portion of chinbar 104, configured to couple to docking cage 112, to be also disposed on the second side 202 of liner 110 and thus within the interior of liner 110. Disposing the attachment portion of chinbar 104 on the second side 202 may allow for easier connection and disconnection of chinbar 104 to and from helmet 102.
[0046] Docking cage 112 may include docking frame 114, posts 116A and 116B, rivet holes 118A and 118B, docking frame datum 120, and posts 122A-D. All or some of docking cage 112 may be molded (e.g., injection molded separately or with liner 110) or formed through another such technique (cast, machined, etc.). All or some of docking cage 112 may be formed from a flexible material that may be configured to deflect when subjected to force typical of that of an impact experienced by helmet assembly 100 or configured to deflect in response to deflection of liner 110. As some or all of docking cage 112 may be disposed on the second side 202 of liner 110, a flexible docking cage 112 may increase wearer comfort or allow for greater protection for the wearer.
[0047] Docking frame 114 may be cage shaped or shaped in another manner and configured to substantially conform to a portion of the second side of liner 110. Docking frame 114 may be a thin thickness to allow for a less bulky helmet and/or a thicker liner 110 to improve user protection. Docking frame 114 may be formed separate from other features of docking cage 112 (and such features may be added after forming of docking frame 114) or may be formed in the same process as that of other features of docking cage 112 (e.g., all features of docking cage 112 may be formed as one injection molded part).
[0048] Posts 116A, 116B, and/or 112A-D may be configured to receive corresponding openings of chinbar 104 to position chinbar 104 relative to docking cage 112. In the embodiment shown in
[0049] Furthermore, docking frame datum 120 may also position chinbar 104 substantially along a direction (e.g., substantially along directions 218/220) to further position chinbar 104 relative to docking cage 112. Chinbar 104 may be positioned on side 204 of docking frame datum 120 by, for example, resting chinbar 104 against side 204 of docking frame datum 120. All or the majority of a wearer's head may be positioned on side 206 of docking frame datum 120 when helmet 102 is worn by the wearer.
[0050] Rivet holes 118A and 118B are configured to receive a rivet. Rivets may pass through corresponding openings in chinbar 104 and, thus, couple chinbar 104 to docking cage 112. Such rivets may include permanent or removable plastic and/or metal rivets and/or other fasteners such as posts, snaps, threaded fasteners, Velcro, adhesives, press fits, and/or other techniques to couple chinbar 104 to docking cage 112.
[0051]
[0052] Channels 130 may be configured to further position chinbar 104 relative to helmet 102. For example, as shown in
[0053]
[0054] Outer portion 142 may be a portion of chinbar 104 substantially forward of datum 148 (e.g., may extend forward substantially in direction 218). Outer portion 142 may, when chinbar 104 is coupled to helmet 102, provide protection to a lower portion of a wearer's face (e.g., the wearer's mouth, chin, jaw, nose, or a portion thereof of one or more of the mouth, chin, jaw, and nose). In certain embodiments, in contrast to the attachment portion, outer portion 142 may not be disposed within helmet 102 when chinbar 104 is coupled to helmet 102.
[0055] When chinbar 104 is coupled to helmet 102, the attachment portion may be disposed within helmet 102. As such, when attachment portion is coupled to helmet 102, as shown in
[0056] The attachment portion may include fingers 140 and may position chinbar 104 relative to docking cage 112 as well as couple to docking cage 112. Fingers 140 may be configured to couple to docking cage 112. For example, one or more fingers 140 may be configured to be inserted into one or more channels 130. As such, fingers 140 may be shaped to be inserted into channels 130 (e.g., may be a shape that substantially conforms or may be received within channel 130). In certain embodiments, fingers 140 may be shaped to contact or more or walls of channels 130 to further position chinbar 104 relative to helmet 102. Furthermore, fingers 140 and/or channels 130 may be shaped to guide insertion of fingers 140 into channels 130 along a certain path. While embodiments described herein include fingers 140 as part of the attachment portion of chinbar 104, other embodiments may not include fingers and may, for example, include a continuous flange of material extending from chinbar 104 as the attachment portion.
[0057] Referring back to fingers 140, fingers 140 may include openings 144A and 144B and rivet holes 146. When chinbar 104 is coupled to docking cage 112, rivet holes 146 may be positioned proximate to rivet holes 118A and 1186. A rivet and/or other fastener may be inserted through rivet holes 118A and 1186 and the respective rivet holes 146 to hold chinbar 104 to docking cage 112. In certain embodiments, a wearer may thus position chinbar 104 proximate to docking cage 112 and may then insert rivets and/or other fasteners through rivet holes 118A and 1186 and the respective rivet holes 146 to couple chinbar 104 to docking cage 112.
[0058] In certain other embodiments, the fastener may be disposed or coupled to one or the other of docking cage 112 or the attachment portion. Thus, docking cage 112 or the attachment portion may, for example, include one or more snap features that can be inserted through a corresponding opening on the other of docking cage 112 or the attachment portion to couple chinbar 104 to docking cage 112.
[0059] Openings 144A and 144B may be configured to receive posts 116A and 1166 (e.g., posts 116A and 116B may be inserted into openings 144A and 144B, respectively) of docking cage 112 to hold chinbar 104 relative to docking cage 112. Furthermore, chinbar datum 148 may include openings 150A-D. Openings 150A-D may be configured to receive posts 122A-D, respectively (e.g., posts 122A-D may be inserted into openings 150A-D). Chinbar datum 148 may be configured to abut side 204 of docking frame datum 120. When chinbar datum 148 abuts side 204 docking frame datum 120, posts 122A-D are inserted into openings 150A-D, and posts 116A and 116B are inserted into openings 144A and 144B. Chinbar 104 may then accordingly be positioned relative to docking cage 112 so that rivets may be inserted through rivet holes 118A and 118B and respective rivet holes 146 to secure chinbar 104 to docking cage 112.
[0060] In other embodiments, chinbar 104 may include any number of openings, posts, datums, and/or other features to position chinbar 104 to docking cage 112. In the embodiment shown, fingers 140 may first be inserted into channels 130 to broadly position chinbar 104 to docking cage 112 while the openings, posts, and datums may then more precisely position chinbar 104 relative to docking cage 112.
[0061]
[0062]
[0063] While portions of docking cage 112 may be disposed within channels 130 interior of outer shell 108, other portions of docking cage 112 may be disposed exterior to docking cage 112. Such a configuration allows for docking cage 112 to be more securely and accurately positioned relative to outer shell 108. A docking cage 112 separate from outer shell 108 may allow for better positioning of chinbar 104 and better distribution of forces (e.g., impact forces) experienced by chinbar 104. Furthermore, docking cage 112 can allow for tighter tolerances for features that interact with chinbar 104, improving fit of finish of the helmet assembly. In certain embodiments, chinbar 104 may couple to both docking cage 112 and outer shell 108. Such a configuration may allow for more secure mounting of chinbar 104 to outer shell and better positioning of chinbar 104 and/or docking cage 112 relative to outer shell 108.
[0064]
[0065]
[0066]
[0067] In block 604, the attachment portion may be coupled to the docking frame. The attachment portion and the docking frame may include formed shapes and corresponding openings, respectively (e.g., posts and corresponding holes as well as forms of other geometric shapes such as depressions and forms configured to interface with the depressions that are configured to position the chinbar relative to the helmet), datums, attachment mechanisms (e.g., snaps or clips or other features that may, when the chinbar is positioned proximate to the helmet, pull the chinbar towards the helmet), and/or other features that may couple to each other.
[0068] Once the attachment portion is coupled to the docking frame, the chinbar may be secured to the helmet in block 606. Thus, one or more of mechanical fasteners (e.g., through rivets, bolts, Velcro, or other mechanical fasteners), adhesives, friction fits, or other techniques may couple the chinbar to the helmet. Accordingly, the chinbar may then be coupled to the helmet.
[0069]
[0070] In block 704, the various components may be assembled into the helmet and the chinbar. As such, for example, the outer shell, liner, and docking frame, as well as possibly other components, may be assembled together to form the helmet. Components of the chinbar may also be assembled together to form the complete chinbar.
[0071] In block 706, the chinbar may be coupled to the docking frame. Coupling of the chinbar to the docking frame in block 706 may be similar to that described in blocks 602 and 604 of
[0072]
