Eyewear with enhanced ballistic resistance

摘要

Eyewear is provided that can comprise a frame, a lens, and at least one retention component that can secure the lens relative to the frame. The frame can be configured to support at least one lens in a field of view of a wearer. The retention component can be supported by the frame and/or the lens and can be movable or fixed relative to the frame and/or the lens. In some embodiments, the retention component can slidably engage an engagement portion of the frame and/or the lens for preventing the lens from separating from the frame in response to a ballistic event. In some embodiments, the eyewear can comprise a faceplate and a pair of straps that attach to the frame of the eyewear in a manner that evenly distributes compressive stresses across the surface of the faceplate.

主权项

1. Eyewear comprising:
a faceplate configured to be positioned against a wearer's head when the eyewear is worn by the wearer, the faceplate defining a centroid; a frame being coupled to the faceplate and being configured to support at least one lens in a field of view of a wearer, the frame comprising first and second guide slots formed along first and second sides thereof, the first and second guide slots defining a radius of curvature having a center point located along a horizontal centroidal axis, the horizontal centroidal axis passing through or sufficiently near the centroid of the faceplate; and a strap for securing the eyewear to the wearer's head, the strap comprising first and second ends and first and second strap engagement mechanisms attached to the respective first and second ends, the first and second strap engagement mechanisms being engageable with the first and second guide slots of the frame to transfer tensile loading of the strap to the faceplate in the form of compressive forces exerted by the faceplate against the face of the wearer, the compressive forces defining a resultant force, wherein the first and second strap engagement mechanisms are slidable within the first and second guide slots of the frame to maintain the orientation of the resultant force in a direction passing through or sufficiently near the centroid of the faceplate for substantially evenly distributing the compressive forces along a surface of the faceplate.
