Abstract

A night vision goggle arrangement includes an assembly for adjusting the position of the goggles relative to a user, means for engaging the assembly with a mounting plate on a helmet, means for locking the assembly to the mounting plate, and release means arranged to unlock and disengage the assembly from the mounting plate.

Claims

1. A night vision goggle arrangement for a helmet, comprising

(a) an adjustable assembly connected with the goggles for adjusting the position of the goggles relative to a user;

(b) means for connecting said assembly with a mounting plate on the helmet;

(c) means for locking said assembly to the helmet mounting plate;

(d) means for releasing said assembly from the helmet mounting plate; and

(e) stored energy means for disengaging and ejecting said assembly from the helmet mounting plate.

2. Apparatus as defined in claim 1, wherein said release means includes

(1) a manually operable rotatable lever for unlocking said locking means;

and

(2) ejection means for disconnecting said connecting means, thereby enabling said assembly to be ejected from the helmet mounting plate.

3. Apparatus as defined in claim 1, wherein said stored energy means comprises a gas motor, and further comprising electrically operable means for actuating said gas motor to eject said assembly from the helmet mounting plate.

4. Apparatus as defined in claim 1, wherein said assembly includes means for tilting the goggles relative to a user, said tilting means including

(1) a rotatable eccentrically mounted shaft;

and

(2) coupling means connecting said shaft with the goggles, whereby rotation of said shaft causes corresponding tilting of the goggles relative to said assembly.

5. Apparatus as defined in claim 2, wherein the helmet mounting plate contains a pair of apertures and further wherein said connecting means comprises a pair of integral flanges extending from said assembly which are inserted into the pair of mounting plate apertures, respectively.

6. Apparatus as defined in claim 5, wherein the helmet mounting plate further contains an opening, and further wherein said assembly locking means comprises a pin connected with said rotatable lever, whereby when said lever is rotated to its locked position, said pin is projected into the mounting plate opening, and when said lever is rotated to its release position, said pin is removed from the mounting plate opening.

7. Apparatus as defined in claim 5, wherein said ejection means comprises an ejection shoe operable upon rotation of said lever to force said flanges out of the mounting plate apertures.
