DETAILED DESCRIPTION

(29) As used herein and in the appended claims, the singular forms a, an, and the include plural references unless the content clearly dictates otherwise. Thus, for example, reference to an adapter includes a plurality of such adapters and equivalents thereof known to those skilled in the art, and so forth, and reference to the adapter is a reference to one or more such adapters and equivalents thereof known to those skilled in the art, and so forth.

(30) In a number of embodiments hereof, helmet accessory adapters include a first connector or helmet connector to connect the adapter to a helmet accessory connection mechanism (for example, including a passage, channel or slot) of a helmet and a second connector or accessory connector to connect to a first helmet accessory. The second connector or accessory connector is also adapted to connect the adaptor to the first accessory in a stowed position when the adapter is not needed to connect to the helmet. In a number of embodiments, the first accessory includes a connector (for example, a frame or a portion thereof) designed to cooperate with the adapter or with a second accessory (for example, a helmet-mounted hearing protector accessory). The second accessory may, for example, include a first connector or helmet connector to connect second accessory to the accessory connection mechanism of the helmet and a second connector or accessory connector adapted to connect the connector of the first accessory to the second accessory. The adapter is designed or adapted to allow the adapter to be stored or stowed on the first accessory when the adapter is not needed to attach the first accessory to the helmet (for example, when the second accessory is attached to the helmet and the first accessory may be attached to the second accessory). The adapter may be removed from storage or stowage on the first accessory and assembled on the helmet to connect the first accessory to the helmet when needed.

(31) For example, in the case of a first accessory or a frame used in connection with a visor to be connected with a helmet, the frame may be connected to the helmet via two adapters hereof which connected to accessory connection mechanisms on each side of the helmet. The adapters cooperate with rearward (with respect to the orientation of the helmet when worn by a user) extending members of the accessory which operatively connect to the adapters. If another or second accessory is to be connected to the helmet which does not require the adapters for connection (for example, a hearing protection accessory or accessories), the adapter may be stowed or stored in connection with the first accessory.

(32) In a number of embodiments, hearing protection accessories for use in systems hereof include a first connector to connect to an accessory connection mechanism of the helmet and a second connector to form an operative connection with rearward extending members of, for example, a visor frame. The visor frame may be connected to the helmet using adapters hereof. However, when it is desirable to use hearing protection accessories, the adapters may be removed from connection with the helmet and stowed upon the visor frame accessory. After connection of the hearing protection accessories to the helmet, the visor frame accessory may be placed in operative connection with the hearing protection accessories with the adapter stowed thereon. If it is subsequently desirable to remove the hearing protection accessories and attach the visor frame accessory to the helmet, the adapters may be removed from stowage on the visor frame accessory and used to attach the visor frame accessory to the helmet.

(33) FIGS. 1A through 1E illustrate an embodiment of an adapter 10 hereof for use in attaching a visor accessory 100 (or other accessory) to a helmet 200. Visor accessory 100 includes a frame 120 to which a visor 140 is attachable. A chin guard 160 may, for example, be attached to a lower end of visor 140. FIG. 1A illustrates a side view of helmet 200 and visor accessory 100 with adapter 10 positioned to be placed in operative connection with an accessory connector or accessory connection mechanism 220 (for example, an accessory passage, channel or slot) of helmet 200. In the illustrated embodiment, helmet 200 includes a rigid shell 210 of a polymeric material into which accessory connection mechanism 220 is monolithically formed. A helmet connector or connector section 20 of adapter 10 includes one or more flexible extending members 24, which may, for example, form a removable or releasable snap fit connection with accessory connection mechanism 220 (see, for example, FIGS. 2A through 2J). In the illustrated embodiment, flexible extending member 24 includes a flange or abutment member 26, which snaps into an abutting connection with accessory connection mechanism 220. In that regard, accessory connection mechanism 220 includes a passage, channel or slot 222 (see, for example, FIG. 2J) into which extending member 24 and one or more extending stabilizing members 28 of adapter 10 are passed. Channel 222 may, for example, be dimensioned such that stabilizing member 28 from a relatively snug fit therein. Abutment member 26, upon passing the lower edge of channel 222 flexes or snaps inward (or to the right in the orientation of FIG. 2J) to form an abutting connection with a lower edge of channel 222. The abutting cooperation of stabilizing members 28 with channel 222, the abutting cooperation of abutment member 26 with the lower edge of channel 222, and the abutting cooperation of a surface 51 of adapter 10 with an upper edge of channel 222 maintain adapter 10 in secure connection with accessory connection mechanism 220. A user may flex extending member 24 outward (or to the left in the orientation of FIG. 2J) to a release position, after connection of adapter 10 to accessory connection mechanism 220, to remove abutment member 26 from abutting connection with accessory connection mechanism 220 to allow removal of adapter 10 from connection with accessory connection mechanism 220.

(34) Adapter 10 further includes an accessory connector or connector section 40 (see, for example, FIGS. 2A through 2G and 2I). In the illustrated embodiment, accessory connection section includes an extending retention channel or a slot 50 formed, in part, by a first flange 52, a second flange 54 and an inner (with respect to the orientation when connected to accessory connection mechanism 220 of helmet 200) wall or surface 56. An extending member or section of an accessory may be slid into connection with retention channel 50 to form a connection therewith. An extending, flexing abutment member 60 may, for example, be formed in wall 56 to contact and form a releasable abutting connection with the extending member of the accessory. In a number of embodiments, adapter 10 is formed monolithically (for example, via a molding process such as an injection molding process) from a polymeric material such as an acetyl polymer.

(35) FIG. 1B illustrates adapter 10 operatively connected to accessory connection mechanism 220 of helmet 200. An extending member 130 or rail of frame 120 of visor accessory 100 is positioned to be slid into connection with retention channel 50 of accessory connector 40 of adapter 10. FIG. 1C through 1E illustrate extending member 130 slid into connection with retention channel 50 of accessory connector 40 of the adapter 10. An inner side of extending member 130 may, for example, include a series of raised sections 132 and intermediate depressions or valleys therebetween (see, for example, FIGS. 3G through 3I) that cooperate with and/or releasably engage flexing abutment member 60 to maintain extending member 130 at a desired position relative to adapter 10.

(36) FIGS. 3A through 3J illustrate a sequence of actions via which adapter 10 may be removed from connection with an accessory such as visor accessory 100 and removed from connection with helmet 200 so that adapter 10 may be stowed or stored on the accessory. FIG. 3A illustrates adapter 10 connected to extending member 130 of visor accessory 100 in an orientation for use in connection with helmet accessory connection mechanism 220. In FIG. 3B, adapter 10 has been removed from connection with extending member 130. Extending member 130 may, for example, include a mechanism 134 which must be actuated to remove adapter 10 from connection with extending member 130. Mechanism 134 may, for example, include a flexible, extending abutment member 134 that may be flexed by the user to allow adapter 10 to be removed from extending member 130. In the illustrated embodiment, extending abutment member 134 angles in a forward direction so that adapter 10 may readily be slid into connection with extending member 130, but abutment member 134 contacts adapter 10 upon sliding adapter 10 rearward along extending member 130 to assist in avoiding unintended disconnection. In FIG. 3B, adapter 10 is illustrated as having been removed from connection with extending member 130. In FIGS. 3C and 3F, adapter 10 is inverted so that helmet connector 20 is oriented upward. In this position, channel 50 of adapter 10 is slid forward into connection with extending member 130 as illustrated in FIGS. 3D and 3G, until it reaches its fully stowed position inward of a joint 124 connecting extending member 130 to a forward portion of frame 120 as illustrated in FIGS. 3E and 3H.

(37) As illustrated in, for example, FIG. 3I, extending member 130 may include an abutment member or surface 138 on or near a forward end thereof, which is abutted by adapter 10 to position adapter 10 inward of joint 124 and to prevent adapter 10 from being disconnected from extending member 130 when slid in a forward direction. Channel 50 of adapter 10 is formed with an open portion between first flange 52 and second flange 54 so that adapter 10 may be stowed inward of joint 124. First flange 52 and second flanges 54 slide into engagement with recesses 126 and 128 respectively formed in joint or joint assembly 124 as illustrated in FIGS. 3F through 3I.

(38) With adapter 10 in the stowed position illustrated in FIGS. 3E and 3H, extending members 130 of visor accessory 100 may be slid into connection with, for example, hearing protection accessories 400 as illustrated in FIGS. 4A and 4B. One of such hearing protection accessories may be placed on each side of helmet 200 to protect the hearing of a user of helmet 200. As illustrated in FIG. 4C, hearing protection accessory 400 includes a helmet connector 420 and an accessory connector 440. In the illustrated embodiment, accessory connector 440 includes passages 442 through which extending member 130 may be slid to connect visor accessory 100 to hearing protection accessory 400 and, thereby, to helmet 200. An outer surface or side of extending member 130 may, for example, include a series of raised sections 136 and intermediate depressions or valleys therebetween that cooperate with accessory connector 440 to position extending member 130 at a desired position relative to accessory connector 440 and helmet 200. If the user decides to remove hearing protection accessories 400, visor accessory 100 may be reattached to helmet 200 via adapters 10, which are safely stowed on visor accessory 100 as described above.
