Abstract

An improved helmet mounting device for an optical device, such as a night vision device, is provided. The mounting device herein includes sliding carriage arms and a pivot member for pivoting the viewing device up and away from the user'"'"'s line of sight. In the depicted preferred embodiments, an optional reinforced mounting fastener system is provided. In another aspect, a movable sensor element may provided on the helmet mount for controlling operation of an attached vision device. In still further embodiments, a breakaway mechanism is provided which allows the user to select between a rigid attachment between the helmet and the optical device and a breakaway attachment wherein the optical device will break away from the helmet when an applied force exceeds a threshold amount of force.

Claims

1. A mounting apparatus for mounting an optical device on a helmet, said mounting apparatus comprising:

a helmet interface assembly removably attachable to the helmet, said helmet interface assembly for providing a generally vertical sliding adjustment of the mounting apparatus relative to the helmet;

a pair of struts extending generally horizontally from said helmet interface assembly;

a carriage member slidably attached to said pair of struts;

a pivot arm assembly pivotally attached to said carriage member, said pivot arm assembly pivotable about a generally horizontal axis extending generally transversely relative to a user;

said pivot arm assembly pivotable between a first, operative position and a second, stowed position, wherein an attached optical device will be positioned before the eyes of a user when the pivot arm assembly is in the first position and out of a line of sight of the user when the pivot arm assembly is in the second position; and

an optical device mounting member attached to said pivot arm assembly, said optical device mounting member removably attachable to an optical device.

2. The mounting apparatus of claim 1, wherein said helmet interface assembly includes a locking and unlocking lever movable between a first, locked position and a second, unlocked position, wherein the helmet interface assembly is in a locked vertical position when the locking and unlocking lever is in the first position and wherein the helmet interface assembly is slidably movable in a generally vertical direction when the locking and unlocking lever is in the second position to provide a generally vertical adjustment of an attached optical device before the eyes of a user when the pivot arm assembly is in the first, operative position.

3. The mounting apparatus of claim 1, further comprising:

a bracket attachable to the helmet; and

said helmet interface assembly attached to said bracket.

4. The mounting apparatus of claim 1, wherein said carriage member is includes a locking and unlocking mechanism for selectively locking said carriage member at a desired position along said pair of struts to provide a generally horizontal fore and aft adjustment of an optical device relative to the eyes of a user when the mounting device is in an operational position.

5. The mounting apparatus of claim 1, further comprising:

a locking member for securing the pivot arm assembly and the carriage member in fixed relative position; and

a push button for selectively disengaging said locking member to permit relative rotation between the pivot arm assembly and carriage member.

6. The mounting apparatus of claim 1, further comprising:

a tilt adjustment mechanism for adjusting a tilt position of an associated optical device relative to an eye of a user.

7. The mounting apparatus of claim 1, further comprising:

said helmet interface assembly including a breakaway connector for securing the mounting device to the helmet, said breakaway connector configured to release upon application of a predetermined force.

8. The mounting apparatus of claim 7, further comprising:

said breakaway connector selectively configurable between a breakaway configuration wherein the breakaway connector is configured to release upon application of a predetermined force, and a nonbreakaway configuration wherein the breakaway connector rigidly secures said first pivot arm assembly to the helmet.

9. The mounting apparatus of claim 1, further comprising:

said optical device mounting member including a mounting shoe for removably receiving a complimentary mounting foot of the optical device.

10. The mounting apparatus of claim 9, further comprising:

said mounting shoe adapted to receive a reinforced mounting foot, said reinforced mounting foot including a reinforcing member received within an integral mounting shoe located on the optical device and said complimentary mounting foot rigidly secured to said reinforcing member.

11. The mounting apparatus of claim 1, wherein the optical device is selected from a night vision goggle device, an electronic night vision goggle device, a night vision binocular device, and a night vision monocular device.

12. The mounting apparatus of claim 1, further comprising:

a sensor element positioned on said mounting apparatus so that a sensor on an attached optical device is in proximity with said sensor element when the pivot arm assembly is in the first, operative position and out of proximity with said sensor element when the pivot arm assembly is in the second, stowed position.

13. The mounting apparatus of claim 12, wherein said sensor element is a magnet and the sensor on the attached optical device is a magnetically actuated sensor.

14. The mounting apparatus of claim 13, wherein the magnetically actuated sensor is selected from a reed switch and a Hall Effect sensor.
