US Patent 7296575 Headgear and interface assembly using same

A headgear for attaching an object to a head of a user that is defined by a support beam and first and second ear loops coupled to opposite ends of the beam. The support beam generally wraps around a back of a user's neck or head and remains below the external occipital protuberance at all times during use of the headgear. This configuration minimizes the contact between the portions of the headgear and the user's hair. The first and second ear loops each include an upper arm adapted to be positioned above the ear, a lower arm adapted to be positioned below the ear, or both. An interface device is coupled to the headgear and held on the user's head by a tensioning force pulling the interface device toward the user.
