Abstract
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.
Claims32
A headgear for attaching an object to a head of a user comprising:
- a beam having a central portion, a first end portion, and a second end portion, wherein the central portion wraps around a back of a user's neck or head and remains below such a user's external occipital protuberance such that the first end portion is located proximate to a right side of such a user's head and the second end portion is located proximate to a left side of such a user's head, and wherein the beam is rigid or semi-rigid;
- a first ear loop operatively coupled to the first end portion of the beam, wherein the first ear loop is rigid or semi-rigid and is generally “C” shaped, wherein the first ear loop includes a first upper arm adapted to be positioned above an ear of such a user and a first lower arm adapted to be positioned below an ear of such a user, and wherein a first gap is defined between the first upper arm and the first lower arm such that the first ear loop is not disposed over a front of such a user's ear responsive to the headgear being donned by a user;
- a second ear loop operatively coupled to the second end portion of the beam, wherein the second ear loop is rigid or semi-rigid and is generally “C” shaped, wherein the second ear loop includes a second upper arm adapted to be positioned above an ear of such a user and a second lower arm adapted to be positioned below an ear of such a user, and wherein a second gap is defined between the second upper arm and the second lower arm such that the second ear loop is not disposed over a front of such a user's ear responsive to the headgear being donned by a user;
- a first strap operatively coupled to the first upper arm or the first lower arm of the first ear loop;
- and
- a second strap operatively coupled to the second upper arm or the second lower arm of the second ear loop, and wherein the headgear does not include a strap disposed over a top of such a user's head when the headgear is donned by a user.

An interface assembly comprising:
- a) a user interface device adapted to contact a portion of a face of a user;
- and
- b) a headgear comprising:
- 1) a beam having a central portion, a first end portion, and a second end portion, wherein the central portion wraps around such a user's neck or head and remains below such a user's external occipital protuberance such that the first end portion is located proximate to a right side of such a user's head and the second end portion is located proximate to a left side of such a user's head, and wherein the beam is rigid or semi-rigid,
- 2) a first ear loop operatively coupled to the first end portion of the beam, wherein the first ear loop is rigid or semi-rigid and is generally “C” shaped, wherein the first ear loop includes a first upper arm adapted to be positioned above an ear of such a user and a first lower arm adapted to be positioned below an ear of such a user, and wherein a first gap is defined between the first upper arm and the first lower arm such that the first ear loop is not disposed over a front of such a user's ear responsive to the headgear being donned by a user,
- 3) a second ear loop operatively coupled to the second end portion of the beam, wherein the second ear loop is rigid or semi-rigid and is generally “C” shaped, wherein the second ear loop includes a second upper arm adapted to be positioned above an ear of such a user and a second lower arm adapted to be positioned below an ear of such a user, and wherein a second gap is defined between the second upper arm and the second lower arm such that the second ear loop is not disposed over a front of such a user's ear responsive to the headgear being donned by a user,
- 4) a first strap operatively coupling the first ear loop to a first portion of the user interface device, and
- 5) a second strap operatively coupling the second ear loop to a second portion of the user interface device, and wherein the headgear does not include a strap disposed over a top of such a user's head when the headgear is donned by a user.

A system for delivering a breathing gas to a patient comprising:
- a) a gas flow generating device that produces a flow of gas;
- b) a conduit having a first end portion operatively coupled to the gas flow generating device and a second end portion, wherein the conduit carries the flow of gas from the gas flow generating device during operation of the system;
- c) a user interface device coupled to the second end portion of the conduit;
- and
- d) a headgear comprising:
- 1) a beam having a central portion, a first end portion, and a second end portion, wherein the central portion wraps around such a user's neck and remains below such a user's external occipital protuberance such that the first end portion is located proximate to a right side of such a user's head and the second end portion is located proximate to a left side of such a user's head, and wherein the beam is rigid or semi-rigid,
- 2) a first ear loop operatively coupled to the first end portion of the beam, wherein the first ear loop is rigid or semi-rigid and is generally “C” shaped, wherein the first ear loop includes a first upper arm adapted to be positioned above an ear of such a user and a first lower arm adapted to be positioned below an ear of such a user, and wherein a first gap is defined between the first upper arm and the first lower arm such that the first ear loop is not disposed over a front of such a user's ear responsive to the headgear being donned by a user,
- 3) a second ear loop operatively coupled to the second end portion of the beam, wherein the second ear loop is rigid or semi-rigid and is generally “C” shaped, wherein the second ear loop includes a second upper arm adapted to be positioned above an ear of such a user and a second lower arm adapted to be positioned below an ear of such a user, and wherein a second gap is defined between the second upper arm and the second lower arm such that the second ear loop is not disposed over a front of such a user's ear responsive to the headgear being donned by a user,
