Light secure eyecup for use with night vision goggles
First Claim
1. An eyecup adapted for use with a goggle to prevent the leakage of light when the eyecup is pressed against the head of a wearer, comprising:
- an inner eyepiece region for providing a sealing engagement with an area between a user'"'"'s eye and nose;
an upper curved eyepiece region providing a sealing engagement with the user'"'"'s brow;
a lower curved eyepiece region providing a sealing engagement with the user'"'"'s cheek;
an outer eyepiece region extending outwardly toward the user'"'"'s temple for providing a sealing engagement therewith;
an interface for connecting said eyecup to the goggle;
an intermediate section between said eyepiece regions and said interface, and including a compressible accordion section for allowing compression of said intermediate section along an axial axis thereof when pressure is applied to said eyecup without deforming said eyepiece regions, andsaid eyepiece regions and interface and intermediate section are of integral construction of a soft pliable material.

Abstract
An eyecup (24) for interfacing a night vision goggle (10) with the eyes of the user (12). A flexible curved eyepiece (28) including a wing (38) provides a tight seal of the periphery of the eyepiece (28) to the occular eye area of the user (12). The seal prevents light (22) emitted from the goggle (10) from escaping out of the confines of the eyecup (24). A fastening sleeve (26) is provided to secure the eyecup (24) about a flange on the goggle (10). An intermediate accordion section (40) allows compression and expansion and maintains the seal between the eyepiece (28) and the ocular eye area. An air vent hole (52) is formed in the accordion section (40) to prevent suction from occurring within the eyecup (24).

4. An eyecup for use with a goggle to interface the goggle to an eye of a user when the eyecup is held in compression against the head of the user, comprising:
a generally flexible rubber body having a central opening, an end for fastening the eyecup to the goggle, and an eyepiece for providing a sealing interface to the ocular area of the use, said eyepiece including an inner region for engaging with that part of the ocular area adjacent the user'"'"'s nose, an outer region for engaging with that part of the ocular area adjacent the user'"'"'s temple, and curved upper and lower regions located between said inner and outer regions, the eyepiece thereby having a contoured edge so as to conform to the right eye when oriented in a first orientation, and to conform to the left eye when rotated 180 degrees, and an accordion section formed of a soft pliable rubber and integral with said body, and formed intermediate said end and said eyepiece regions for allowing compression of said eyecup without substantial distortion of said flexible eyepiece regions, said accordion section being formed around an entire circumference thereof. - View Dependent Claims (5, 6, 7, 8, 9, 11, 15, 16)
