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: An eyewear assembly has a frame with removable lenses. The eyewear assembly may include upper and lower frame portions that are separable from one another at a bridge region of the frame using a linkage. A finger actuator actuates the linkage to cause the upper frame to move away from the lower frame, exposing at least one edge of the lenses for removal. The separated upper frame portion and lower frame portion may be held in a stable open position. After lens removal or replacement, the linkage may be actuated to reconnect the upper frame portion and lower frame portion, thereby enclosing the lenses.

Abstract: Attachment systems for attaching accessories to a helmet shell and their methods of use are described. In one embodiment, an attachment system may include a first attachment portion mounted to a helmet shell and extending through an opening in an associated accessory. The attachment system also may include a second attachment portion that is selectively connectable to the first attachment portion. A surface of the second attachment portion facing the helmet shell engages with a bearing surface of the accessory to selectively attach the accessory to the helmet shell. In certain embodiments, the first and second attachment portions may be selectively connected to one another using a connector that moves the second attachment portion both vertically and horizontally relative to the first attachment portion when the connector is tightened.

Abstract: A helmet accessory attachment member includes a finger-actuatable lock configured to secure an accessory attachment member mount to a helmet mount as part of securing an accessory such as a mandible guard to a helmet. The lock includes a pivot arm with a rotation axis that is parallel to the helmet surface, and also includes one or more blocking surfaces on the pivot arm to engage with grooves on the helmet mount. The lock may be positioned on a slidable insert of the accessory attachment member.

Abstract: Methods and devices for attaching a battery to a helmet and attaching a battery to an additional device are disclosed. A battery may be mounted to the rear center of a helmet. Attaching and detaching a battery to and from a helmet may be performed with a tool or by hand. The battery may be used to power multiple devices through separate contacts, and a device may be attached to the battery while the battery mounted to a helmet. The battery also may be detached from the helmet and serve as a portable energy source.
