Claims

1 . A jaw support comprising:

a chest engaging member provided to rest on an upper area of the chest of a user below the jaw, the chest engaging member comprising a U-shaped first elongate member;

a neck support extending from the chest engaging member around a rear side of the neck of the user; and

a jaw support member connected to the chest engaging member, the jaw support member comprising a U-shaped second elongate member;

wherein the jaw support member is pivotable between a first position, in which the jaw support member is adjacent the chest engaging portion, and a second position, in which the jaw support member moves away from the chest engaging member such that the user may rest their chin on the jaw support member, the first and second elongate members comprising flat elongate members having corresponding shapes such that, in the closed configuration, a surface of the second elongate member is adjacent and parallel to a surface of the first elongate member along the lengths thereof.

2. A jaw support in accordance with claim 2, wherein first and second ends of the second elongate member are rotatably mounted to respective first and second ends of the first elongate member such that the second elongate member is rotatable about an axis passing through the first and second ends of the first elongate member.

3. A jaw support in accordance with claim 4, wherein the first and second ends of the first and second elongate members lie in parallel planes and intermediate portions of the first and second elongate members are twisted relative to the first and second ends such that, in use, when the first and second ends are adjacent sides of the neck, the intermediate portions lie parallel to the surface of the chest of the user.

4. A jaw support in accordance with claim 3, wherein when the U-shaped first elongate member is oriented in a generally horizontal plane, the first and second ends of the first and second elongate members are oriented in vertical planes and the intermediate portions of the first and second elongate members are angled relative to a vertical plane such that the intermediate portions are at or near horizontal.

5. A jaw support in accordance with claim 4, wherein the intermediate portion of the jaw support member includes an indent to receive the chin of a user.

6. A jaw support in accordance with any one of the preceding claims, wherein the neck support comprises first and second arms extending outwardly away from first and second ends of the first elongate member respectively.

7. A jaw support in accordance with claim 6, wherein the first and second arms comprise relatively flat curved members such that the first and second arms curve around towards the rear of the neck of the user.

8. A jaw support in accordance with claim 7, wherein the first elongate member and the first and second arms are integrally formed from a resilient flexible material.

9. A jaw support in accordance with claim 8, wherein distal ends of the first and second arms are separated by a gap.

10. A jaw support in accordance with claim 9, wherein a strap is provided to connect between distal ends of the first and second arms.

1 1 . A jaw support in accordance with any one of the preceding claims, wherein a locking mechanism is provided between the first and second ends of the jaw support member and the first and second ends of the chest engaging member such that the jaw support member may be retained in one or more positions relative to the chest engaging member.

12. A jaw support in accordance with claim 1 1 , wherein the locking mechanism is moveable between a first position in which the jaw support mechanism is restricted from moving towards the chest engaging portion but may move away from the chest engaging portion and a second position, in which the jaw support member is moveable towards the chest engaging portion.

13. A jaw support in accordance with claim 12, wherein the locking mechanism is moveable from the first position to the second position by operation of actuators provided adjacent the connection of the first and second elongate members.

14. A jaw support in accordance with claim 13, wherein ends of the second elongate member include cylindrical end portions having openings for receiving protrusions on ends of the first elongate member and wherein the locking mechanism is provided within the openings.

15. A jaw support member in accordance claim 14, wherein the actuators comprise levers extending radially outwardly from the cylindrical end portions.

16. A jaw support in accordance with claim 15, wherein the locking mechanism comprises:

a part cylindrical protrusion extending outwardly from ends of the first elongate member defining an arcuate gap;

an inner cylindrical protrusion located inside the part cylindrical protrusion; a ring including the lever, the ring being located about the part cylindrical protrusion having an arcuate protrusion located in the gap for rotational movement between a first and a second position;

an arcuate spring clip located between the part cylindrical protrusion and the inner cylindrical protrusion having an outer end located adjacent the gap;

wherein movement of the arcuate protrusion from the first position to the second position moves the outer end of the arcuate spring clip inwardly to disengaged from teeth provided around an inner surface of the cylindrical end portion, thereby allowing the jaw support member to rotate towards the chest engaging portion.

17. A jaw support in accordance with claim 16, wherein the engagement between the outer end and the teeth is such that rotation of the cylindrical end portion in a direction which would move the jaw support member away the frame is not restricted with the ring in the first position.
