The present invention generally relates to a visor for use with a helmet and, more particularly, to a helmet mounted visor assembly for coupling eye protection to a helmet.
Eye protection for protecting a user's face and/or eyes are used in different environments and for many different purposes. Depending on the use and/or environment in which eye protection is desired, it may be desired to couple the eye protection to a helmet worn by a user. For example, eye protection may be attached to helmets for use in operation of vehicles, such as aircraft, or during military engagement.
During use, eye protection, such as a visor coupled to a helmet, may be positioned relative a user's face in a position desired by the user. In some instances, external forces may act on the eye protection and helmet causing the eye protection to move away from the position desired by the user. For example, during operation of an aircraft, the user may experience high accelerations forces, or high G forces, which may cause the eye protection to move away from the desired position. In some situations, vibrations experienced during use may also cause the eye protection to be moved away from the desired position. In some instances, high wind speeds experienced during ejection from an aircraft may cause the eye protection to be moved away from the desired position.
In use, it may also be desired that the eye protection fit tightly around or close to one or more other accessories used by the user. For example, the eye protection may be positioned above an oxygen mask used during operation of an aerial vehicle. Placement of the oxygen mask relative to the helmet may be different for different users. For example, the placement of the oxygen mask is dependent on the shape and size of a user's face. Therefore, there is a need to provide a helmet mounted visor assembly configured to couple eye protection to a helmet in a plurality of positions relative the users face to allow for variations in mask placement while keeping the position of the eye protection secured during use.

The helmet mounted visor assembly 100 may include a visor 106 for providing eye protection to a user. The visor 106 may be configured to pivot relative to the helmet cover 102. For example, the visor 106 may be pivotably coupled to the helmet cover 102. The visor 106 may include mounting arms 108 disposed on opposite ends of the visor 106 that are each configured to pivotably couple the visor 106 to helmet cover 102. The visor 106 may pivot about axis A between a stowage position (
Mounting arms 108 may be coupled to visor 106 by one or more fasteners (e.g., screws, bolts). The mounting arms 108 may be disposed on opposite ends of visor 106. The visor 106 may have a length extending along the visor 106 from one mounting arm 108 to the mounting arm 108 on the opposite side. In one embodiment, the visor 106 is optically opaque to lasers and/or lights. However, visor 106 may have any level of transparency. For example, visor 106 may be fully transparent, semi-transparent, or may be optically opaque. In some embodiments, the transparency of visor 106 is altered by varying the base material of visor 106 and/or by adding color/laser absorptive dies. In some embodiments, the addition of additional dies may not increase the thickness of visor 106. Further, absorptive and reflective coatings may be used on visor 106 to alter the transparency of visor 106.
The visor 106 may include a latching mechanism 110 for locking the visor 106 in the stowage position or any one of the one or more usage positions. The latching mechanism 110 may be configured to interface with an accessory mount (e.g., shroud mount 114) included in the helmet mounted visor assembly 100. For example, the shroud mount 114 may be configured to engage with latching mechanism 110 to releasably lock the visor 106 in one or more usage positions, as discussed in more detail below. The shroud mount 114 may be disposed on a front portion of the helmet cover 102. For example, the shroud mount 114 is positioned on the front portion of the helmet cover 102 and is generally centrally located between the left and right sides of the helmet cover 102. In some embodiments, the shroud mount 114 extends at least partially outward and away from the outer surface of the helmet cover 102. In some embodiments, a bottom peripheral edge of the shroud mount 114 is proximate a bottom peripheral edge of the helmet cover 102. In some embodiments, the helmet cover 102 may define an aperture 115 configured to receive the shroud mount 114. The shroud mount 114 may extend at least partially through the aperture 115 to couple to the helmet cover 102. In some embodiments, an inner surface of the shroud mount 114 is positioned interior to the inner surface of the helmet cover 102 and an outer surface of the shroud mount 114 is positioned exterior to the outer surface of the helmet cover 102. In some embodiments, the inner surface of the shroud mount 114 may be generally flush with the outer surface of the helmet cover 102. In some embodiments, the inner surface of the shroud mount 114 may be at least partially recessed within the helmet cover 102 such that it is positioned between the inner and outer surfaces of the helmet cover 102.
In some embodiments, the shroud mount 114 is configured to couple one or more accessories to the helmet mounted visor assembly 100 and/or the helmet 200. For example, the shroud mount 114 may be configured to couple an optical device (e.g., night vision goggles, binoculars) to helmet cover 102. For example, the shroud mount 114 may include a recessed receiving area 122 configured to receive an accessory. In some embodiments, the accessory may be releasably coupled to the helmet cover 102 via the receiving area 122 of the shroud mount 114. In some embodiments, the shroud mount 114 is configured to receive an accessory while the visor 106 is in a usage position.

Shroud mount 114 may include one or more flanges 125 disposed above ratchets 124a-124c. Put another way, the flanges 125 may be disposed on an outer surface of the shroud mount 114 opposite an inner surface of the shroud mount 114 and the ratchets 124a-124c may be positioned between the outer surface and inner surface of the shroud mount 114. In some embodiments, the ratchets 124a-124c are positioned between the flanges 125 and the outer surface of the helmet cover 102 when the shroud mount 114 is coupled to the helmet cover 102. The one or more flanges 125 may be configured to retain engagement of the latching mechanism 110 with the shroud mount 114 during vibration or in high winds. For example, the flanges 125 may prevent the latching mechanism 110 from disengaging with one of the ratchets 124a-124c by providing a surface exterior to the exterior surface of the helmet cover 102. Shroud mount 114 may include a flange 125 on the right side (shown) and left side (not shown) disposed above corresponding ratchets 124a-124c. Flange 125 may form a slot between the flange 125 and helmet cover 102 in which the ratchets 124a-124c are disposed. The flange 125 may constrain movement of latching mechanism 110 such that the latching mechanism 110 may be prevented from disengaging with ratchets 124a-124c during vibration or high winds. For example, the flange 125 may prevent latching mechanism 110, when engaged with a corresponding ratchet 124a-124c, from moving in a direction other than the direction defined by ratchets 124a-124c (e.g., a direction away from the outer surface of the helmet cover 102). It will be understood that the flanges 125 and/or ratchets 124a-124c may be sized such that the latching mechanism 110 is able to move toward or away from the outer surface of the helmet cover 102 while still preventing the latching mechanism from disengaging the ratchets 124a-124c due to movement away from the outer surface of the helmet cover 102. Engagement of the latching mechanism 110 and ratchets 124a-124c is discussed in greater detail below with reference to

The shroud mount 314 may also be different from shroud mount 114 in that the flange 325 is longer than flange 125. For example, the flange 325 may extend further along the outer surface of the shroud mount 314 in a direction extending from the top of the shroud mount 314 to the bottom of the shroud mount 314, when compared to flange 125 of shroud mount 114. Put another way, the flange 325 extends further along the direction that the visor 106 rotates about the helmet cover 102 than flange 125. In this manner, the flange 325 may further reduce the risk of the visor 106 from disengaging from shroud mount 314 due to movement of the visor 106 in a direction away from the outer surface of the helmet cover 102. It will be understood that ratchets 324a-324c are generally the same as ratchets 124a-124c. Furthermore, it will be understood that the remaining features, structure, and/or characteristics of shroud mount 114, as described in relation to the shroud mount 114, and as described in relation to any other components of the helmet mounted visor assembly 100, also apply to shroud mount 314. Put another way, shroud mount 314 functions generally the same as shroud mount 114, with the exception of the extended flange 325 and stops 327. Therefore, it will be understood that shroud mount 314 and 114 may be interchanged with one another in helmet mounted visor assembly.
