Abstract

A helmet mount for attaching a viewing device to a helmet includes a helmet interface assembly removably attachable to the helmet. A pivot arm is attached to the helmet interface assembly and is pivotal about a horizontal, transverse axis. A carriage member is carried on the pivot arm and slidable between the distal end and the proximal end of the pivot arm. The carriage member includes a bridge member integral therewith, the bridge member including a first fastener configured to removably attach a first viewing device and a second fastener configured to attach a second viewing device.

Claims

1. A helmet mount for attaching a viewing device to a helmet, the mount comprising:

a helmet interface assembly removably attachable to the helmet;

a pivot arm attached to the helmet interface assembly and pivotal about a horizontal, transverse axis, the pivot arm having a proximal end and a distal end;

a carriage member carried on the pivot arm and slidable along the pivot arm between the distal end and the proximal end of the pivot arm, the carriage member having an upper extent lying in an upper plane extending parallel to said pivot arm;

the carriage member including a bridge member integral therewith, the bridge member disposed beneath the upper plane, the bridge member including opposed first and second side surfaces, the first and seconds side surfaces being on opposite transverse sides of the pivot arm;

a first side section including a first mounting arm hingedly attached to a first viewing device mount;

a second side section including a second mounting arm hingedly attached to a second viewing device mount;

the first side surface including a first plurality of electrical contacts configured to be mated with corresponding contacts on the first mounting arm;

the second side surface including a second plurality of electrical contacts configured to be mated with corresponding contacts on the second mounting arm;

the first mounting arm including a first fastener element extending from a first mating surface and the second mounting arm including a second fastener element extending from a second mating surface;

the first side surface having a first opening removably receiving the first fastener element, the first fastener element and the first opening being positioned to guide mating of the first plurality of electrical contacts with the corresponding contacts on the first mounting arm; and

the second side surface having a second opening removably receiving the second fastener element, the second fastener element and the second opening being positioned to guide mating of the second plurality of electrical contacts with the corresponding contacts on the second mounting arm.

2. The helmet mount of claim 1, further comprising:

the first viewing device mount including a first mounting shoe receptacle configured to removably attach to a mounting shoe of a first viewing device; and

the second viewing device mount including a second mounting shoe receptacle configured to removably attach to a mounting shoe of a second viewing device.

3. The helmet mount of claim 2, further comprising:

the first side section including a first hinge that allows rotation of a first attached viewing device between a viewing position before a first eye of a user and a first non-viewing position out of a line of sight of the user; and

the second side section including a second hinge that allows rotation of a second attached viewing device between a second viewing position before a second eye of a user and a second non-viewing position out of the line of sight of the user.

4. The helmet mount of claim 3, wherein the first and second hinges each pivot about a pivot axis that is parallel to optical axes of the first and second attached viewing devices.

5. The helmet mount of claim 2, further comprising:

an electrical circuit for electrically coupling a power supply to one or both of a first attached viewing device and a second attached viewing device.

6. The helmet mount of claim 2, wherein the first and second mounting shoe receptacles are linearly movable with respect to the first and second side sections, respectively, along a horizontal axis orthogonal to optical axes of the first and second viewing devices when the first and second side sections are in a deployed position.

7. The helmet mount of claim 1, wherein the helmet interface assembly includes one or both of:

a vertical adjustment assembly for positioning an attached viewing device at a desired vertical position; and

a tilt adjustment assembly for adjusting a viewing angle of an attached viewing device.

8. The helmet mount of claim 1, wherein the pivot arm pivots between a lower position and an upper position for use and stowage, respectively, of a viewing device attached to the bridge member.

9. The helmet mount of claim 1, wherein the carriage member is slidable along the pivot arm to a desired position between the proximal end and the distal end of the pivot arm.

10. The helmet mount of claim 1, wherein the helmet interface assembly includes a breakaway connector which causes at least a portion of the helmet mount to detach from the helmet upon the application of a predetermined force.

11. The helmet mount of claim 1, further comprising:

a gear rack on said pivot arm;

a slide lock carried on said carriage member, the slide lock having locking teeth which intermesh with the gear rack to secure the carriage member at a desired position on the pivot arm, the slide lock being manually actuatable to selectively move the locking teeth out of engagement to provide fore-and-aft adjustment of the carriage member.

12. The helmet mount of claim 1, further comprising a captured spring within said carriage member urging the locking teeth into engagement with the gear rack.

13. The helmet mount of claim 1, further comprising a viewing device.

14. The helmet mount of claim 13, wherein the viewing device comprises a pair of monocular viewing devices.

15. The helmet mount of claim 1, wherein each of the the first and second side sections is adapted for mounting one or more viewing devices selected from the group consisting of an optical device, opto-electronic device, sighting device, targeting device, passive night vision device, enhanced night vision device, thermal imaging device, infrared imaging device, short-wave infrared imaging device, helmet mounted display screen, and combinations thereof.

16. The helmet mount of claim 1, wherein the first side surface is keyed to mate with the first mating surface and the second side surface is keyed to mate with the second mating surface.

17. The helmet mount of claim 1, further comprising:

at least one device interface member configured to attach to a different type of viewing device, wherein each of the at least one device interface member is attachable to the bridge member and interchangeable with one or both of the first and second side sections.
