Background of the Invention

[0002] Military personnel often need to carry items of equipment on their helmets. Such items may include night vision goggles, headlamps, communications equipment, etc. The helmets typically have a few mounting openings for supporting such items. This arrangement, however, does not lend itself to the user's being able to accommodate a large number of items mounted at different locations on the helmet, and to customize the mounting locations.

Detailed Description

[00017] The present invention relates to a headborne integration system. The invention is applicable to headborne integration systems of various differing constructions and configurations. As representative of the invention, Figs. 2-14 illustrate a headborne integration system 10 that is a first embodiment of the invention, including an attachment platform 12 (Fig. 6) illustrated in use with a helmet 13 (Fig. 1). The system 10 also includes other components, such as a face shield 20 and a mandible 22 (Fig. 8), and possibly others. Other systems and platforms in accordance with the invention may include different components or different combinations of components.

[00018] The attachment platform 12 (Fig. 6) is a three piece structure that includes a front platform section 14, a left platform section 16, and a right platform section 18. The left and right platform sections 16 and 18, as illustrated, are substantially if not completely mirror images of each other. In other embodiments, that need not be the case.

[00019] The platform 12 (Figs. 2-6) is modular, providing the capability of adding or removing sections depending on mission specific needs. For example, as shown in Fig. 3, the front section 14 can be used alone with the helmet 13. As shown in Fig. 5, the side sections 16 and 18 can be used alone. And, as shown in Fig. 6, all three sections 14-18 can be attached to the helmet 13 at one time. These configurations can all be provided with the use of only a screwdriver, as discussed below.

[00020] The three platform sections 14-18 are preferably made from a strong but lightweight plastic, such as polycarbonate or another suitable material. The color of the platform sections is preferably selected to match both the Woodland and the Desert versions of the US Military camouflage helmet covers.

[00021 ] Existing military helmets, such as the LWH helmet and the ACH/MICH helmet, have suspension mounting holes at several locations. The platform 12 is adapted to be mounted on either the LWH or the ACH/MICH helmet, using the suspension mounting holes, as described below.

[00022] The LWH helmet is shown in the drawings, and has suspension mounting holes 30, 32, 34 and 36 on the sides, and one or more NVG mounting holes 38 on the front. The ACH/MICH helmet (not shown) is similarly provided with mounting holes at different locations into which a different attachment platform 12 can be secured.

[00023] The front platform section 14 (Fig. 2) includes two arms 52 that are disposed at the back and sides of the section. Each arm 52 has a fastener opening 54 which, in the illustrated embodiment, is a through hole in the material of the platform section adapted to receive the shank of a primary mounting screw 40. The end portion 56 of the arm 52, having the fastener opening 54, is offset outwardly from the plane of the arm, adjacent a shoulder 58. This offset allows for an arm of a platform side section 16 or 18 to be introduced between the front section arm 52 and the helmet 13, as illustrated in Fig. 6, when the side section 16 or 18 is used along with the front section 14. Alternatively, if the platform front section 14 is used alone, the offset portion 56 of the arm is pulled down tighter against the helmet 13.

[00024] The attachment platform 12 makes use of the existing mounting holes 30-38 on the helmet 13. The two fastener openings 54 in the platform section 14 overlie two of the holes 30 and 32 in the helmet 13. As shown in Fig. 3, fasteners in the form of primary mounting screws 40 are placed through the fastener openings 54 in the platform section 14, and engage in the mounting holes 30 and 32 in the helmet 13. One preferred type of fastener 40 is a 5/8 inch, 10-32 large-bearing-surface screw.

[00025] The fasteners 40 could include tamper proof features, if desired. Using the existing helmet holes provides structural support for the platform 12, on the helmet 13, without adding unnecessary weight of other components. As shown in the drawings, the platform 12 mounts directly onto the helmet 13. Alternatively, the platform 12 can be mounted (not shown) over a fabric helmet cover of the type that is often worn directly on the helmet itself.

[00026] The front platform section 12 (Figs. 2 and 3) has a portion 42 defining a pocket or recess 44 for receiving night vision goggles (NVG) 46. This portion 44 includes features specially adapted to receive and support known NVG systems. A fastener opening 47 receives another one of the fasteners 40, into the front helmet mounting hole 38, to help secure the front platform section 14 to the helmet 13. Inside the pocket 44 is a separate recess 46 that is adapted to receive a name/rank plate.

[00027] The pocket 44 may incorporate a slot 45 to affix an off the shelf light, or headlamp, if desired. As one example, the pocket 44 may thus be configured to accommodate the popular Petzl Tactikka Plus Adapt headlamp. Different headlamps can be accommodated by using different mounting attachments (plates) fixed to the center section 14 of the platform 12. [00028] Above the NVG pocket 44 is a loop 49. This loop 49 is adapted to receive a strap (not shown) that would extend up and back over the helmet 13, to the rear edge of the helmet. Such a strap can be used for securing other items to the helmet 13.

[00029] The front platform section 14 also includes, to either side of the NVG mounting portion 42, a pair of openings 50. These openings 50 can be used to support other items that are appropriate for the front of a helmet, such as a light, etc. The items can be clipped onto or otherwise secured to the helmet platform 12 at these locations 50. Alternatively, separate adapters (not shown) can be provided that are specially configured to fit securely in the openings 50, and that are specially configured to receive and support one or more items. Further, these openings 50 can be left open, thus reducing the weight of the front platform section 14 as compared to a solid front section. Still further, these openings 50 can be closed, leaving a solid area suitable for mounting additional items, for example in the manner described below with reference to Fig. 11.

[00030] The left platform section 16, or left side section, which in the illustrated embodiment is a mirror image of the right platform section 18, is shown in detail in Figs. 4 and 5. The left section 16 has a generally triangular configuration overall, including a top leg 60; a back leg 62 that extends down and forward from the back end of the top leg 60; and a front leg 64 that extends down and rearward from the front end of the top leg 60. Other configurations are possible.

[00031] When the side section 16 is mounted on the helmet 13, the top leg 60 of the side section 16 extends along the lower side edge 66 (Fig. 1) of the helmet, over the portion of the helmet that covers the user's ear. The front leg 64 and the back leg 62 extend outward away from the user's ear.

[00032] Fastener openings 68 and 70 (Fig. 4) are located at opposite ends of the top leg 60. The fastener openings 68 and 70, in the illustrated embodiment, are through holes adapted to receive fasteners 40. The distance between the fastener openings 68 and 70 is selected to be the same as the distance between the mounting holes 32 and 36 on the left side of the helmet 13. As a result, the left side section 16 is adapted to fit directly onto the helmet 13. Fasteners 40 extend through the fastener openings 68 and 70 into the holes 32 and 36.

[00033] The front leg 64 includes two stem receptacles 72 and 74. The upper receptacle 72 is a face shield stem receptacle. The lower receptacle 74 is a mandible stem receptacle. The receptacles 72 and 74 extend generally horizontally, front to back, when the platform side section 16 is mounted on the helmet 13 and the helmet is in use. Each receptacle 72 or 74 preferably includes at least one notch or detent 76 for engaging, as described below, a portion of a stem that is received in the receptacle 72 or 74.

[00034] The receptacles 72 and 74 are located adjacent to the user's ear when the helmet 13 is in use. The ears typically are about at the center of gravity of the head. Thus, the weight of the face shield 20 and of the mandible 22 are supported at about the center of gravity of the head, as desirable.

[00035] Like the front platform section 14, the side platform section 16 provides an area on the platform 12 for mounting helmet accessories and items. These items can be mounted in many different areas on the side section 16. In this case, one mounting area is located on the top leg 60 of the side section 16. One type of item that can be installed is a universal mounting item such as a picatinny rail 80 (Fig. 5). The picatinny rail 80 is one attachment item capable of holding other items that mount onto such a rail. The rail 80 can be attached to the left platform section 16 as shown, or, alternatively, to the right section 18.

[00036] The mounting of the rail 80 to the platform top leg 60 is done with a press fit nut attachment system as illustrated in Figs. 9 and 10. The system includes a plurality of nuts 84 that are press fit into the material of a section 14, 16 or 18 of a platform 12.

[00037] The nuts 84 are preferably located in recesses 86 in the back side or inside surface 88 (facing the helmet) of the platform 12. At each recess 86, a through hole 91 extends between the outer surface 93 of the platform and the recess 86. The through hole 91 enables a headed threaded fastener 95 to extend from outside the platform 12, and screw into the nut 84, through the item and through the platform 12, to clamp an item to the platform 12.

[00038] The recesses 86 are preferably complementary in configuration to the nuts 84. For example, the nuts 84 shown in Figs. 9 and 10 are hexagonal, as are the recesses 86. As a result, when the nuts 84 are press fit in the recesses 86, they are prevented from rotating relative to the platform 12.

[00039] Recesses 86 and nuts 84 can be located at various places on the platform 12. They can be located at predetermined places for mounting specific items in those specific places, as with the example of the picatinny rail 80. Alternatively, as shown schematically in Fig. 11, a number of the press fit nuts 84 can be located in a matrix 90 in a platform section, such as the section 14. This allows the user to customize where the user wants to mount an item on the platform 12; the user is not restricted to placing a given item in a given location on the platform section. Still further, the material of the platform can be molded to accommodate user-specific locations of press fit nuts. In one example, one or more parts or areas of the platform can be provided with a plurality or matrix of closed cell locations which the user can pop out to accommodate one of the press fit nuts. In this manner, the user can selectively place an item in a location not specifically provided for during manufacture of the platform.

[00040] Other possible items (not shown) that can be supported by this press fit nut attachment system include an annular socket for receiving a lens cap of a night vision goggle, so that, it does not have to dangle from the NVG. Another example is a simple pocket or receptacle to provide a location to clip lights, cameras or other components to the platform 12. A third example is the picatinny rail 80. Almost any item can be supported thus, at any selected location in the platform sections 14, 16 and 18.

[00041] The face shield 20 (Figs. 7, 8 and 12), which is part of the system 10, includes a frame 92 and a lens 94. The frame 92 has a configuration that conforms to the edge of the LWH and ACH/MICH helmets, to prevent water from hitting the wearer's face. The frame 92 also has a portion that prevents water from dripping onto the inside surface of the shield. The frame 92 is large enough to accommodate ESS-brand Interchangeable Component Eyeshield (ICE) 2X spectacles. The frame 92 does not interfere with the sighting of a rifle having a reflex optic.

[00042] The face shield 20 may have a 3 mm thick polycarbonate lens 94 to meet the ballistic requirement of MIL-V-4311C, Clause 3.5.10. The face shield 20 weighs 0.3 pounds and is able to withstand the impact of a 17-gram Fragment-Simulating Projectile (FSP) at a speed much greater than the 550-ft/sec requirement. The thickness of the lens 94, and its curvature, do not adversely affect outward vision. The lens 94 is preferably coated with an anti-fogging and scratch-resistant film.

[00043] The face shield 20 is releasably attached (locked) to the platform 12. The frame 92 of the face shield 20 includes two rearwardly projecting temples, or stems 96. The stems 96 are configured to releasably, lockingly engage in the face shield receptacles 72 in the side sections 16 and 18 of the platform 12. A simple detent mechanism such as a ball or enlarged portion engagable in a recess is provided between the stems 96 and the receptacles 72. The user plugs the stems 96 into the receptacles 72, and the face shield 20 latches onto the platform 12. To remove the face shield 20, the user pulls outward with sufficient force, and the face shield releases from the platform 12. The retention force can be selected as desired; it need not be the same as the retention force for the mandible 22. Other attachment mechanisms are possible.

[00044] The mandible 22 (Figs. 8 and 13), which is part of the system 10, is a hybrid soft-armor device including a rigid endoskeleton (frame) 100 that is designed to provide both structural (blunt impact) and ballistic protection. The frame 100 has stems 101 for mounting to the platform 12.

[00045] The mandible 22 incorporates hybrid soft armor 102 in some locations on the frame 100 to provide ballistic protection while allowing sighting of a rifle without inhibiting target acquisition time. The soft armor 102 is located on the portions of the frame 100 where the soldier can be expected to shoulder a rifle, the user's sighting side. To that end, the frame 100 is open at a pocket 104 on at least that one side, the user's sighting side. The soft armor 102 is releasably (or permanently) mounted in the pocket 104. The presence of the soft armor portion 102 enables sighting of the rifle, while still providing ballistic protection.

[00046] If the mandible frame 100 is made symmetrical, there is a similar pocket 104 on the opposite side of the frame. In this pocket 104, the user can insert or attach a supplementary piece of the hard frame material, to close that soft spot and provide additional or full protection.

[00047] The mandible 22 is preferably color-matched to the platform 12, and has room inside it to accommodate voice communication devices, fluid replenishment through a hydration pack nozzle, and adequate air circulation for comfort. The illustrated mandible 22 weighs about 0.78 pounds and meets ballistic protection requirements.

[00048] The attachment method of the mandible 22 to the platform 12 may be similar to that of the face shield 20. The mandible 22 may have a second detent position, in which the mandible is slid out slightly from the platform side sections 16 and 18, to allow more room for air circulation in a non-combat situation.

[00049] The mandible 22 is preferably installed and removed with one hand. Thus, a single switch or release lever or mechanism is provided, operable by one hand, to release the locks on both sides of the mandible 22 that is, between both stems 101 and their respective mandible receptacles 74.

[00050] Fig. 14 illustrates schematically one exemplary locking/release mechanism 110 that provides the functions and characteristics needed. (The illustrated mechanism is only one of many that may be suitable; others that provide for one-handed operation, simultaneously releasing both stems 101, may also be used.) At the two ends of the mechanism 110 are the stems 101 of the mandible 22. Each stem 101 includes a ball detent 112 that can either be located radially outward, as shown, or be moved radially inward into a recess in a socket member 114 of the stem.

[00051 ] When the parts are in the position shown, the ball 112 protrudes outward, engaging the detent or notch 76 (Fig. 4) or other structure on the receptacle 74 of the platform side section 16 or 18. If the user pushes on an actuator 114, for example with the thumb, in the direction indicated by the arrow 116, while pressing in an opposite direction 118 with fingers as shown, the actuator 114 rotates two gears 120, that rotate two pulleys 122. The pulleys 122 pull on two cables 124, pulling the socket members 114 to a position in which the balls 112 can move radially inward. Thus, the stems 101 can be released from the receptacles 74 in the platform 12.
