Abstract

In one aspect, an eye shield for a respirator mask of the type having a face piece adapted to fit over the face of a user is provided. The eye shield includes a visor assembly including a visor surrounded by a frame, the visor assembly configured to be removably mounted in an opening in the face piece. One or more fastener elements are provided on the frame for removably securing the visor assembly to the face piece. The visor is formed of a transparent material which filters electromagnetic energy emissions at one or more preselected wavelengths. In certain embodiments, one or more head up display assemblies are attached to the visor assembly for projecting a human viewable image to the visor.

First claim

What is claimed is:

1. An eye shield for a respirator mask of the type having a face piece adapted to fit over the face of a user, the eye shield comprising:
a visor assembly including a visor surrounded by a frame, the visor assembly configured to be removably mounted in an opening in the face piece;
a sealing surface disposed on the frame which sealingly engages a surface on the face piece when the eye shield is attached to the face piece;
one or more fastener elements on the frame for removably securing the visor assembly to the face piece;
the visor formed of a transparent material which filters electromagnetic energy emissions at one or more preselected wavelengths; and
at least one head up display assembly attached to the visor assembly and disposed on an exterior facing side of the eyeshield for projecting a human viewable image to the visor, wherein the at least one head up display assembly includes one or more manually actuable input devices disposed on a housing of the at least one head up display assembly, the one or more manually actuable input devices for controlling operation of the at least one head up display assembly.

2. The eye shield of claim 1 , wherein the visor assembly is disposed over a transparent lens covering the opening in the face piece.

3. The eye shield of claim 1 , wherein the one or more wavelengths correspond to a wavelength of a military laser system.

4. The eye shield of claim 1 , wherein each of the at least one head up display assembly includes an image source for generating an image and projection optics for projecting the image onto the visor.

5. The eye shield of claim 4 , wherein the image is generated responsive to image data received from an associated life support system.

6. The eye shield of claim 5 , wherein the image comprises indicia selected from the group consisting of one or more of vital signs of the wearer, a geographical location of the wearer, ambient air temperature, a battery level of a power supply in the life support system, ambient air quality, targeting cross hairs, a reticle, and any combination thereof.

7. The eye shield of claim 1 , wherein the at least one head up display assembly further includes an RF transceiver for receiving a signal representative of an image to be displayed.

8. The eye shield of claim 1 , wherein the one or more manually actuable input devices are accessible by a user wearing the eye shield.

9. The eye shield of claim 1 , wherein the one or more manually actuable input devices include one or more buttons.

10. A kit comprising a plurality of eye shields interchangeably attachable to and detachable from a respirator mask, the respirator mask having a face piece adapted to fit over the face of a user, the plurality of eye shields comprising:
at least a first eye shield and a second eye shield;
the first eye shield including a first visor assembly including a first visor surrounded by a first frame, the first visor assembly configured to be removably mounted in an opening in the face piece, a first set of one or more fastener elements on the first frame for removably securing the first visor assembly to the face piece, the first visor formed of a transparent material which filters electromagnetic energy emissions at a first wavelength;
the second eye shield including a second visor assembly including a second visor surrounded by a second frame, the second visor assembly configured to be removably mounted in the opening in the face piece, a second set of one or more fastener elements on the second frame for removably securing the second visor assembly to the face piece, and the second visor formed of a transparent material which filters electromagnetic energy emissions at a second wavelength; and
at least one head up display assembly attached to one or both of the first visor assembly and the second visor assembly, the at least one head up display assembly disposed on an exterior facing side of the eyeshield, the at least one head up display assembly for projecting a human viewable image to a respective one of the first visor and second visor, wherein the at least one head up display assembly includes one or more manually actuable input devices disposed on a housing of the at least one head up display assembly, the one or more manually actuable input devices for controlling operation of the at least one head up display assembly.

11. The kit of claim 10 , further comprising the respirator mask.

12. A breathing apparatus, comprising:
a face piece adapted to fit over the face of a user;
an eye shield including a visor assembly, the visor assembly having a visor surrounded by a frame, the visor assembly configured to be removably mounted in an opening in the face piece;
a sealing surface disposed on the frame which sealingly engages a surface on the face piece when the eye shield is attached to the face piece;
one or more fastener elements on the frame removably securing the visor assembly to the face piece;
the visor formed of a transparent material which filters electromagnetic energy emissions at one or more preselected wavelengths; and
at least one head up display assembly attached to the visor assembly and disposed on an exterior facing side of the eyeshield for projecting a human viewable image to the visor, wherein the at least one head up display assembly includes one or more manually actuable input devices disposed on a housing of the at least one head up display assembly, the one or more manually actuable input devices for controlling operation of the at least one head up display assembly.

13. The breathing apparatus of claim 12 , further comprising:
one or more fasteners for attaching an air purifying element.

14. The breathing apparatus of claim 12 , further comprising a life support apparatus.

15. The breathing apparatus of claim 12 , wherein the life support apparatus is selected from the group consisting of a self-contained breathing system, an air purifying respirator, and a combined self-contained breathing system and an air purifying respirator.

16. The breathing apparatus of claim 12 , wherein the one or more manually actuable input devices are accessible by a user wearing the eye shield.

17. The breathing apparatus of claim 16 , wherein the one or more manually actuable input devices include one or more buttons.

18. The kit of claim 10 , wherein the one or more manually actuable input devices are accessible by a user wearing the eye shield.

19. The kit of claim 18 , wherein the one or more manually actuable input devices include one or more buttons.
