Claim 8:
9. The helmet apparatus according to claim 8, wherein each face mask latch device comprises:
a face mask latch body attached to the helmet proximate to a corresponding face mask latch pin;
a face mask latch casing rotatably coupled to the face mask latch body and having a handle extending therefrom;
a face mask latch disposed between the face mask latch casing and the helmet, said face mask latch having an opening therein and a hook portion configured to grasp the corresponding face mask latch pin; and
a rotatable face mask latch shaft member fixedly attached to the face mask latch casing, said face mask latch shaft member having an offset cam attached to an end thereof, wherein the offset cam is inserted into the opening in the face match latch;
whereby rotation of the face mask latch casing in a first direction causes the hook portion of the face mask latch to move outward away from the face mask latch shaft member and rotate away from the face mask latch pin, thereby releasing the face mask latch pin; and
whereby rotation of the face mask latch casing in a second direction causes the hook portion of the face mask latch to rotate toward the face mask latch pin and move inward toward the shaft member to grasp the face mask latch pin.
