COMPACT FOLDING ARCHITECTURE FOR HEAD MOUNTED DEVICE

An example of a hinge mechanism for a head mounted device is provided. Aspects of the disclosure relate generally to folding the head mounted device in a secure fashion for convenient storage and transportation. The head mounted device may have an asymmetrical shape with an enlarged and elongated first side arm. In this regard, the hinge mechanism allows the head mounted device to fold at an angle so as not to interfere with a second side arm of the head mounted device. The head mounted device may also implement a flexguard component configured to bend along with the hinge structure so as to protect internal components that become exposed due to the folding of the hinge. An axial cam system is also implemented to allow for the secure and comfortable folding and opening of the head mounted device.
