Mandible guard
A helmet assembly having a helmet, a mandible guard, and an accessory attachment system that is used to selectively attach and secure the mandible guard to the helmet is disclosed. In some embodiments, the mandible guard is arranged to be detached from a first side of the helmet while remaining secured to a second side of the helmet. In such embodiments, the mandible guard may be moved outwardly and away from a wearer as the mandible guard pivots around the accessory attachment system attached to the second side of the helmet.
1. A method comprising:
removably securing a first side of a mandible guard to a helmet via a first attachment arm, the first attachment arm extending from a first helmet connection region to a first mandible guard connection region;
removably securing a second side of the mandible guard to the helmet via a second attachment arm extending from a second helmet connection region to a second mandible guard connection region, wherein the mandible guard has a mouth covering portion, and wherein when the mandible guard is secured to the helmet with the first and second attachment arms, the mouth covering portion is aligned with a midline of the helmet, and movement of the mandible guard in a direction from a front of the helmet to a back of the helmet is prevented;
detaching the second attachment arm from the helmet; and
moving the mandible guard out of a protection position while the first attachment arm remains secured to the helmet by rotating the mandible guard via a hinge connector that connects the mandible guard and the first attachment arm, wherein the hinge connector has a first axis of rotation about which the mandible guard rotates relative to the first attachment arm and a second axis of rotation about which the mandible guard rotates relative to the first attachment arm.
2. The method of claim 1 , wherein moving the mandible guard out of the protection position includes rotating the mandible guard to a position adjacent the first attachment arm.
3. The method of claim 1 , further comprising:
re-securing the second attachment arm to the helmet;
detaching the first attachment arm from the helmet;
moving the mandible guard out of the protection position while the second attachment arm remains secured to the helmet.
4. The method of claim 3 , wherein moving the mandible guard out of the protection position while the second attachment arm remains secured to the helmet includes rotating the mandible guard relative to the second attachment arm.
