## Abstract

A headgear can be worn on a user's head to adjustably fix a mouthpiece inserted in an oral cavity. The headgear includes: a front pad brought into contact with and pressed against a front pressure point of an outer surface of the buccinator between the zygomatic bone and the mandible in the face region; one or more rear pads brought into contact with and pressed against one or more rear pressure points so that a resultant force becomes a reaction force paired with a pressing force of the front pad, in a region from the top to the back of the head; a frame fixing the front pad and the rear pads; a front horizontal bar fixed to the frame at a position in front of the lip region of the head; and an adjustment part installed on the front horizontal bar to mount the mouthpiece.

## Claims

### Claim 1

A headgear for fixing a mouthpiece, the headgear being worn on a user's head so as to adjustably fix the mouthpiece inserted in an oral cavity, and the headgear comprising:
one or more front pads adapted to contact with one or more predetermined front pressure points, in a face region of the head;
one or more rear pads adapted to contact with one or more predetermined rear pressure points so that a resultant force becomes a reaction force paired with a pressing force of the front pads, in a region from top to back of the head;
a front frame configured to support the front pads;
a rear frame configured to support the rear pads;
a front horizontal bar configured to be connected to the front frame or the rear frame and adapted to be disposed in front of the lip region of the head, wherein the front horizontal bar has a double structure of an upper bar and a lower bar; and
an adjustment part configured to be provided on a vertical rod installed between the upper bar and the lower bar, wherein the adjustment part is adapted to be disposed at a position in front of a lip region of the head to mount the mouthpiece,
wherein the rear frame is adapted to be disposed above ear regions of the head, the front frame is adapted to be disposed in front of the ear region of the head, with one end thereof connected to the rear frame, and the other end thereof connected to the front pads, and the one or more predetermined front pressure points are predetermined portions of a maxilla on a face, and are positions that do not limit functions of eyes, a nose, and a mouth, and
wherein the mouthpiece has a pair of wires protruding forward, front ends of the wires are connected to each other by a horizontal rod, and the horizontal rod extends to form an outer peripheral portion.

### Claim 2 (depends on 1)

The headgear of claim 1, wherein the one or more predetermined front pressure points are positions of an outer surface of a buccinator between a zygomatic bone and a mandible.

### Claim 3 (depends on 2)

The headgear of claim 2, wherein the front frame is configured to extend forward downward from the rear frame to pass through depressed portions between the ear regions and the zygomatic bone of the head and extend to below the zygomatic bone.

### Claim 4 (depends on 2)

The headgear of claim 2, wherein in order to maximize an action force designed to be applied to the oral cavity by the mouthpiece, and to minimize a reaction force generated by the mouthpiece in response to the action force, the front and rear frames and the front and rear pads are formed such that the reaction force is transmitted to and canceled by at least one of the front and rear frames through the adjustment part.

### Claim 5 (depends on 1)

The headgear of claim 1, wherein the front frame is configured to extend forward downward from the rear frame to pass through depressed portions between the ear regions and the zygomatic bone of the head and extend to below the zygomatic bone.

### Claim 6 (depends on 1)

The headgear of claim 1, wherein in order to maximize an action force designed to be applied to the oral cavity by the mouthpiece, and to minimize a reaction force generated by the mouthpiece in response to the action force, the front and rear frames and the front and rear pads are formed such that the reaction force is transmitted to and canceled by at least one of the front and rear frames through the adjustment part.
