Abstract: Earphones which attach to an interior of a helmet are disclosed. Physical attachment of the earphones to the helmet result in an electrical connection in some embodiments. The headphones may be used without the helmet through the use of strap holder adapters in some embodiments.

Abstract: A helmet assembly is provided including a front mount configured to attach to the front of the helmet above a brim of the helmet, a mandible for protecting a portion of the user's face, a lower edge rim mounting portion such as a halo attached along the lower edge of the helmet for securing the mandible to a helmet and providing power and data conduits. The front mount provides a center top mounting arrangement that operatively connects a center top location of the face shield to a center front mount on the helmet. The mount provides frontal bracket portions for mounting accessories. The helmet assembly provides a helmet shell with a curved shape having a surrounding reinforcing ridge. A reeling system is provided for adjusting front and lower chin straps. Other improvements in helmet assemblies are also disclosed.

Abstract: Various helmet systems as well as their methods of use are described. In one embodiment, a helmet system includes an anchor and a carrier that include corresponding interlocking features that interact to support and maintain an orientation of the carrier relative to the helmet shell when mounted thereon. In another embodiment, a helmet system includes a carrier connected to a helmet shell, and an accessory attachment mount that is selectively connected to the carrier. In yet another embodiment, a helmet system includes a connection and corresponding alignment features between a helmet shell and an accessory attachment mount to both support and maintain an alignment of the accessory attachment mount when it is attached to the helmet shell.

Abstract: Systems and methods for attaching an accessory to a helmet are disclosed. A helmet accessory mounting interface may be attached to a receptacle. The receptacle may be removably or permanently received by a carrier. The carrier may be attached to a helmet having a particular shape and size. The carrier also may be configured to receive any selected type of a plurality of receptacle types which, in turn, corresponds to a particular mounting interface for a helmet accessory. The receptacle may be receivable, in some embodiments removably, by any one of a number of different types of carriers.

Abstract: A helmet assembly including a mandible bracket configured to connect a mandible to a helmet, at least one strap connected to the mandible bracket and configured to extend from the mandible bracket to a rear portion of a helmet. The assembly includes at least one strap guide having a strap engaging portion connected to the strap along a length of the strap for connecting the strap to a helmet, and a fastener engaging portion configured to connect to a fastener attached to a helmet.

Abstract: A helmet accessory attachment system may include an attachment portion comprising a biasing element, a position member, and a movable member. The movable member may be selectively moveable between a home position which is a first distance from the position member and a release position which is a second distance from the position member. The biasing element may bias the movable member toward the home position. The helmet accessory attachment system also may include a mounting portion attachable to a helmet. The mounting portion may include a first channel to receive the movable member at a first opening and a second channel to receive the position member at a second opening. A third distance between the first opening of the first channel and the second opening of the second channel may be greater than the first distance from the movable member to the position member in the home position.

Abstract: Systems and methods for selectively attaching an accessory mount to a helmet are disclosed. A carrier may be used to position the accessory mount on the helmet. The accessory mount may be positioned on the helmet without engaging the rim of the helmet. The carrier may be compatible with various accessory mounts to permit mounting of different accessories. The accessory mount may be a powered mount for attachment to a Night Vision Device (NVD) such as Enhanced Night Vision Goggles (ENVG), or the accessory mount may be a non-powered accessory mount.

Abstract: A helmet assembly including a mandible bracket configured to connect a mandible to a helmet, with at least one strap connected to the mandible bracket and configured to extend from the mandible bracket to a helmet. The assembly includes at least one strap guide having a strap engaging portion connected to the strap along a length of the strap for connecting the strap to a helmet. The strap guide is removably attachable to the helmet, and in some embodiments the strap guide may be attached and/or removed through movement along a lengthwise direction of the strap, including in a horizontal direction. The assembly may secure an accessory other than a mandible to the helmet, and sufficient force on the accessory may remove the strap guide from the helmet.

Abstract: Methods and devices for adjusting the position of a mandible guard relative to a helmet are disclosed. Adjustment of the mandible guard may be performed by a user while the user is wearing the helmet and/or without the use of tools. A mandible guard adjustment system may be combined with an attachment system for attaching and removing the mandible guard to a helmet.
