Description:
CROSS REFERENCE TO RELATED APPLICATION 
     This application claims the benefit of U.S. Provisional Application No. 61/804,963 filed on Mar. 25, 2013. The above identified patent application is herein incorporated by reference in its entirety to provide continuity of disclosure. 
    
    
     BACKGROUND OF THE INVENTION 
     Field of the Invention 
     The present invention relates to an inversion chair and the method of use. More specifically the invention relates to an inversion chair including a fixed backrest and a rotatable seat, whereby the inversion chair and the method of exercise are configured to provide a treatment for migraines. The chair is adapted to operate as either a standard, upright seat, or alternatively an invertible chair, depending on the position of a user support bar and the desires of the user at a given time. The treatment method combines the head muscles stretching and alteration of the blood flow within the head by utilizing the user&#39;s inverted position while using the chair. 
     Many individuals suffer from different types of headaches, such as tension, cluster, frontal sinus headaches, and migraines. Migraines are a common and serious neurovascular disorder that affects many individuals. These migraines may cause symptoms, such as throbbing headaches, nausea, vomiting, and light and sound sensitivity. The intense throbbing and pain associated with migraines are debilitating to individuals. Moreover, these migraines may cause a loss of productivity and functionality during everyday tasks. 
     A migraine headache is a result of the brain abnormal sensory modulation reaction to any environmental or physical changes. This definition refers to many different environmental or physical factors such as change in weather (humidity or temperature), change in barometric pressure, dry and dusty atmosphere, high winds, traveling, changing job or school, bright or flickering light, loud noise, intense smells or vapors, certain foods, alcohol, over sleeping, under sleeping, hormone fluctuation, stress and many more. Although the cause of the migraine differs for each individual, what is known is that it involves changes to the nerve pathways and chemicals of the brain. These changes may result in alteration of the flow of blood within the brain. 
     It is known that migraines occur as a result of environmental and/or physical triggers, these triggers may be different for each individual. For some individuals, however, may notice early symptoms called “prodrome”. These symptoms can include one or more of dizziness, fatigue, mood changes, food cravings, changes in vision, and etc. Shortly after the noticed symptom the blood flow in the head begin to change gradually and muscle and nerve spasms start to cause pains in different areas of the head. These symptoms provide the first warning that a migraine is about to begin. If the headache is not properly treated on this stage it may develop and create a more painful and harder to treat situation. Traveling of the pain signals through the trigeminal nerve to the brain stem and then into the brain sensory receptor (thalamus) may cause brain nerve activation resulting in brain blood vessels dilation (vasodilatation). This is when the full blown migraine episode starts to happen. So, there is a time period between receiving early migraine symptoms and reaching the pain signals to the trigeminal nerve of a migraineur. This time period is the main focus of this invention which is referred to as “prodromal phase” in this document. Migraine prodromal phase has an onset of two hours to two days before the excruciating migraine pain starts. 
     Shortly after performing the present exercise method during the prodromal phase, the migraine headache start reversing before the pain signals can reach to the brain center and turn into a full blown migraine headache. The inverted position may allow the blood flow to evenly distribute through the head while the stretching exercise method cause to relieve any muscle or nerve spasm in the head area thus the travel of the pain signals to the brain center is being prevented or stopped within minutes. 
     The presented method of treatment using the inversion chair comprise of two sets of exercises which should be performed in the right order in order to get a complete relief from the migraine attack during the prodromal phase. 
     The present invention provides an apparatus and method of use that is adapted to stop the onset of a migraine at the first migraine attack signs during the prodromal phase. Moreover, the present invention can be utilized as a preventive measure as part of a schedule routine, wherein the device is used before the emergence of migraine symptoms. It is the goal of the present invention to enable an individual to orient themselves in an inverted position, thereby allowing the blood flow to evenly distribute into the head and neck area while head muscle stretching exercises are designed to relieve any muscle tensions or spasms, thereby preventing pain signals from traveling to the brain through the trigeminal nerve and before the headache may get out of control. Furthermore, in addition to preventing the migraine from occurring, the present method facilitates the strengthening of the head muscles, which can significantly decrease the frequency and the intensity of future migraine attacks by decreasing the susceptibility to any sudden environmental or physical change, as well as improving the overall health of the user. 
     The present invention provides an inversion chair combining with two complimentary exercise methods that are configured to provide therapeutic relief from migraine headaches. Based on the “Neurovascular Theory” of the migraine, the presented invention utilizes the basic fact that whether the abnormal reaction creating a migraine attack initially starts in nervous system or blood vessels or a combination of both it may cause an uneven blood flow which leads to head muscle spasm during the prodromal phase. The present chair is designed to orient a user in a position to even out the blood flow within the head including forehead, upper face, sides and back of the head, while the exercise methods release any spasm in the muscles or nerves in the mentioned areas as well as increasing the circulation of the oxygen which all, can create a reverse mechanism for migraine symptoms during the prodromal phase and stop the migraine attack within minutes. More importantly utilizing the chair and practicing the exercise method can significantly reduce the intensity and frequency of the future migraine attacks. The user then can keep up with practicing the exercise method and utilizing the inversion chair to maintain the results. When not needed as an inversion therapy device, the present chair is designed such that it can easily be converted into a traditional, upright chair that will not invert. 
     Since there is no known cure for migraine headaches, individuals spend considerable amounts of money on the treatment of attacks thereof. A variety of medications have been developed to treat these debilitating conditions; however these medications are taken every day as a preventive measure, or taken as needed to relieve the pain of an active migraine in progress. Most users would rather not take daily medication or be required to take medication after a migraine attack has already begun, which often times medications are also less effective if is not used earlier in an attack. The present invention is provided as a non-medicinal treatment that a user can engage in on a daily basis for acute attacks or daily maintenance. 
     Similar solutions currently available involve hanging one&#39;s self over a couch and bending over in a manner that changes the center of gravity of a user and alters blood flow. These solutions, however, are limited by the furniture around the house, which may not be capable of providing a proper treatment angle, may lack securing features, and lack the stability necessary to perform the migraine treatment. The present invention is presented as a safe and reliable method of inversion that does not require use of other furniture articles. 
     Existing inversion chairs in the art are furthermore designed to provide therapeutic treatment to the back of a user by relieving the pressure between the joints of the spine. Some of these treatment devices may also provide a change in blood flow, however, these devices typically have a solid headrest portion that restricts the movements of the head, and furthermore does not provide a chair that can be used as a traditional seat during periods of non-use as an inversion therapy device. 
     The present invention relates to a new and improved inversion chair that is configured to provide migraine treatment by altering the flow of blood within the head and neck area. The assembly provides a chair that can invert the user when desired, and operably act as an upright seat between uses with the repositioning of a support bar on the assembly. The assembly comprises a chair-supporting frame having first and second sides connected by a backrest. The sides of the frame comprise L-shaped members having an upstanding side member and a base member that are connected together by a curved member. A seat is rotatably connected to the sides of the frame. The seat comprises an upper user support bar and a lower leg support bar, which provide support for a user when in an inverted orientation. The user support bar is removable for either locking the chair in an upright position or for use as a lap support for the user when inverted. 
     Description of the Prior Art 
     Devices have been disclosed in the prior art that relate to inversion devices. These include devices that have been patented and published in patent application publications. These devices generally relate to devices that include long backrests that rotate backward to decompress the spine. The following is a list of devices deemed most relevant to the present disclosure, which are herein described for the purposes of highlighting and differentiating the unique aspects of the present invention, and further highlighting the drawbacks existing in the prior art. 
     One such device in the prior art is U.S. Pat. No. 5,967,956 to Teeter. The device provides a mount for a tilting inversion exercise table that is configured for rotatably supporting a user thereon. While the device of Teeter provides a rotation of a user similar to that of the present invention, it differs in that it fails to provide a fixed backrest and a seat that is rotatable. 
     Another device, U.S. Pat. No. 3,081,085 to Girolamo discloses a back posture and stretch board. The device provides a treatment that promotes proper back posture, while at the same time effect a stretching of the back. The device board of the device comprises handles, a sitting bad, and straps for securing the feet. In use, the board rotates backward while a user is lying on top of the board, thereby letting gravity decompress and stretch the spine. The device of Girolamo, however, differs from the present invention in that it fails to provide a rotatable seat that is configured to apply migraine relief, and furthermore a means of locking the seat when not used for its intended purpose. 
     U.S. Pat. No. 5,334,123 to Rutherford describes a device for performing a tilting exercise apparatus for the back. The device is a rearward tilting chair set within a frame, whereby the rotation of the chair facilitates the decompression of the spine of a user. The chair is tilted back to a limited degree so that while the spine is allowed to decompress, the blood does not rush to the head. While the device of Rutherford is similar in nature and relevant to the present invention, the device differs in that it fails to provide a rotatable seat having a fixed back, and further differs in that the rotational angle does not allow for the altering of blood flow within the head in order to provide migraine relief. 
     Yet another prior art device, U.S. Pat. No. 4,739,749 to Lindley describes an Orthospinal chair for exercising the spinal column and back muscles by placing tension on the spine through partial inversion. The chair comprises a restraining strap that is secured around the hip area of the user, thereby retaining the user in the chair during inversion. Although the device of Lindley provides an inversion chair similar to that of the present invention, it differs in that it fails to provide an inversion chair having a fixed backrest and a rotatable seat portion, whereby the chair is configured for the relief and treatment of migraines. 
     Finally, U.S. Pat. No. 6,464,296 to Sumner describes a therapeutic inversion chair. The device comprises a frame, having a pivotally connected chair, having different relative inclinations. When used for inversion, a stop is mounted on the chair to restrict rearward pivotal movement of a person from an upright position to an inverted position. While the device of Sumner is similar in nature and relevant to the present invention, it differs by failing to provide a fixed backrest and a rotatable seat having a leg support thereon. 
     The present invention is an inversion chair assembly configured to provide relief for a user who is experiencing or is about to undergo a migraine, whereafter the assembly can be locked in a static state for use as a traditional seating device. An invertible seat is connected between a first and second frame sides and can be locked into position or support a seated user when transitioning from an upright position to an inverted position. The seat is rotatable about the frame, and comprises lower leg and an upper user support bar, providing upper and lower body support for the user when the chair is inverted. The support bar is positionable over the lap of the user, or alternatively is movable to a position below the seat and between the frame sides within clips under the seat. The support bar extends and locks the seat in an upright state. The length of the support bar is adjustable to either be greater or smaller than the width between the frame sides, thereby locking the chair in a horizontal position when used in a traditional manner. 
     It is submitted that the present invention is substantially divergent in design elements from the prior art and consequently it is clear that there is a need in the art for an improvement to existing inversion chair devices. In this regard the instant invention substantially fulfills these needs. 
     SUMMARY OF THE INVENTION 
     In view of the foregoing disadvantages inherent in the known types of inversion chair devices and inversion therapy devices now present in the prior art, the present invention provides a new inversion chair assembly that can be utilized for providing convenience for the user when a therapeutic relief from migraines is desired, or a traditional, upright chair is desired. 
     It is therefore an object of the present invention to provide a new and improved inversion chair assembly that has all of the advantages of the prior art and none of the disadvantages. 
     It is another object of the present invention to provide an inversion chair assembly with a frame having a fixed backrest and a rotatable seat therein. 
     Another object of the present invention is to provide an inversion chair assembly with a rotatable seat having an upper user support bar and a lower leg support, whereby the upper and lower body of the user is secured when the assembly is used to invert the user. 
     Yet another object of the present invention is to provide an inversion chair assembly that includes a removable user support bar that is positionable above the seat as a lap support of the user, and removable and positionable beneath the seat to lock the chair in an upright configuration between uses. 
     Other objects, features and advantages of the present invention will become apparent from the following detailed description taken in conjunction with the accompanying drawings.

     DETAILED DESCRIPTION OF THE INVENTION 
     Reference is made herein to the attached drawings. Like reference numerals are used throughout the drawings to depict like or similar elements of the inversion chair. For the purposes of presenting a brief and clear description of the present invention, the preferred embodiment will be discussed as used for the treatment of migraines through inversion therapy or used as a traditional, upright chair between inversion therapy uses. The figures are intended for representative purposes only and should not be considered to be limiting in any respect. 
     Referring now to  FIGS. 1A through 1D , there are shown perspective and frontal views of the inversion chair  10  of the present invention, which is configured for providing treatment for migraines by operably positioning a user in an inverted state when not acting as a traditional, upright chair. The assembly comprises a frame  15  having a first frame side and a second frame side that are substantially identical to one another and which are connected to each other by a backrest frame. The backrest frame  30  separates the frame sides and spans the gap therebetween, whereby the frame sides are parallel to one another and said backrest frame  30  is substantially perpendicular thereto. Each of the frame sides are a substantially L-shaped member comprising an upstanding member  22 , a base member  23 , and a curved member  25  connected therebetween to the ends of the upstanding member  22  and the base member  23 . Along the base member  23  of each side frame is an upstanding post forming inversion grips  65  for an inverted user to grasp if necessary while inverted. The upstanding member  22  and curved member  25  connect to the sides of the backrest frame  30 , thereby providing a stable frame  15  structure. The backrest frame  30  is preferably covered by a padding material, while the frame sides may have a soft covering to soften any contacts with a seated user. Extending upwards from the backrest frame  30  is an adjustable and/or removable headrest  48 . 
     A seat  35  is rotatably supported between the first and second frame sides by a pair of angled, upstanding seat support members  55  and a pair of seat support plates  60 , both of which are positioned in the same plane as the frame sides. The seat support plates  60  are secured within an upper area of frame sides and between the upstanding  22  and curved  25  frame members. The upstanding seat support members  55  form a triangular shape with an upper apex defined by the rotatable connection of the seat  35 . A rotational joint  57  that includes a bore and pin supports the seat  35  in a rotatable condition, whereby the joints  57  of each frame side are aligned to allow the seat  35  to pivot from a substantially horizontal condition to a substantially vertical position. This enables a user to sit upright and to transfer into a substantially inverted position while seated in the seat. 
     The construction of the seat and its ability to rotate are visualized. The seat  35  preferably comprises a padded cushion positioned over a seat frame. Along the rear of the seat there is connected a first and second support bar arm  42 , which is rotatably connected to the seat frame via a cylindrical sleeve  41  and a perpendicular portion of the support bar arms that forms an internal sleeve member  47  within the sleeve  41 . This configuration forms a revolute joint or hinge joint between the arms  42  and the seat frame, thereby enabling the user support bar  40  to be advantageously positioned on the lap of a user. The first and second support bar arm  42  extend from the rear of the seat frame and terminate at a support bar socket  44 , which is adapted to receive the end of the user support bar  40  positioned over the seat  35 . The user support bar  40  is a removable structure that first serves as a support over the lap of an inverted user, and then alternatively as a means to lock the seat  35  in a horizontal state when the assembly is used as a standard, upright chair. 
     Along the rear of the seat  35  and positioned along the inward surface of the frame side is a rear seat support  49  (see  FIG. 1C ). The rear seat support  49  comprises a ledge that prevents the seat  35  from rotating backwards about its rotational joint  57 . The rotational joint  57  is forward of the rear seat support  49 , whereby the seat  35  can rotate freely forward, and rearward to the extent to which the seat lower surface contacts and bears against the rear seat supports  49 . These elements allow the seat  35  to remain horizontal when the assembly is used as a standard, upright seat. 
     When the user support bar  40  is engaged into the sockets  44  of the arms  42 , they move with the chair  35  itself as it transitions from an upright position to an inverted position. Likewise, below the chair there is positioned a footrest  45  with a first and second footrest perch  46  for the user to brace their lower body while inverted. The user support bar  40  is configured to retain a user against the seat  35  when the user is in an inverted position, while the footrest can be positioned over or under the user&#39;s feet to limit any relative motion between the user and the seat  35 . The user support bar  40  is removably insertable into the sockets  44  of the support bar arms  42 , thereby enabling a user to enter and exit the chair and further enable the repositioning of the user support bar under the seat  35  to lock the same in a horizontal position (see  FIG. 2A ). After the user support bar  40  is removed from the arms  42 , the bar  40  may be placed within support bar clips  50  located along the underside of the seat  35  and the support arms  42  can be lowered to the same level as the seat  35  and be placed right beside the seat  35  (see  FIG. 2A ) on both sides. The user support bar  40  is length adjustable such that it remains shorter than the distance between the first and second frame sides while in use as an inversion chair (see  FIG. 1B ), and thereafter adapted to extend outward when the bar  40  is deployed below the seat to lock the same in a horizontal state (see  FIG. 2A ). This latter positioning of the bar  40  prevents the seat  35  from rotating when it is not intended. 
     Referring now to  FIG. 2A  there is shown a view of the seat  35  within the sides of the frame  15  being used as a traditional, upright chair. The user support bar  40  is first removed from sockets  44  of the support bar arms  42 , thereby enabling a user to enter and exit the seat. The seat frame of the present invention comprises a forward end and a rear end, the rear end supporting the support bar arms  42  and the underside of the forward end comprising one or more support bar clips  50 . The support bar clips  50  are configured to hold the user support bar  40  therein when the seat  35  is not in an inverted orientation. The length of the user support bar  40  is shorter than the width between the sides of the frame when used as an inversion chair, but its length is adjustable such that it can be extended when deployed below the seat  35 . By adjusting the length of the support bar  40 , users can create a greater length than the separation of the frame sides, whereafter the positioning of the user support bar  40  between the seat underside and the curved members  25  of the frame sides locks the seat  35  in a horizontal state and prevents rotation thereof. This secures the seat  35  from any sudden or unwanted rotational, enabling use thereof as a traditional chair. 
     Referring to  FIG. 2A , The support bar arms  42  are also adjustable in angle with respect to the seat frame such that they can rotate the positioning of the support bar downwards or upwards based on user&#39;s body type and his or her comfort. The support bar arms  42  also act as optional handles that are hingedly supported from the seat  35  and are positioned at the sides of the seat  35  when the support bar  40  is removed at the end of treatment or when the seat is not used as a therapeutic inversion chair. 
     Referring now to  FIG. 2B , there is shown a view of the present invention in a condition wherein the seat  35  is free to rotate about the frame sides, while the user support bar  40  and support arms  42  are supported over the lap of a user. Both the user support arms  42  and the leg supports  45  are length adjustable, in that they comprise a telescoping structure to enable longer or larger individuals to fit into the device, and the user supports to be sufficiently snug against the user to prevent the user from falling from the seat when inverted. When in use as an inversion chair, the user support bar  40  is removed from the clips  50  below the seat  35 , and is secured within the sockets  44  of the support bar arms  42 . The sockets  44  preferably comprise a locking mechanism to prevent inadvertent separation between the sockets  44  and user support bar  40 . Meanwhile, the user support bar  40  may also comprises a padded exterior length. The support bar arms  42  are telescopic, and are configured to adjustably rest on the waist of a user when the inversion chair  10  is in use. Additionally, the leg supports  45  are also telescopic, thereby enabling users of varying heights to comfortably use the device. 
     The separation between of the support bar arms  42  and the width of the support bar  40  are shorter than the separation between the curved member  25  of the frame sides such that the support bar  40  can easily pass between the curved members  25  while the user is inverted. The functionality of the support bar  40  while attached to support bar arms  42  is to protect the user from falling out of the chair in an inverted position. 
     Referring now to  FIG. 2C , there is shown a view of the user support bar  40  and its length adjustable construction. The user support bar  40  may take on several different designs allowing its length to be adjustable, and it is not desired to limit the design of the user support bar  40  to any one specific construction. The following is one contemplated means of adjusting the length of the user support bar  40 , wherein the bar  40  comprises a first and second member  39  in telescopic relationship with one another. A first and second pin hole  37  location are provided for a spring pin  36  to be secured thereinto, thus providing a first and second locked length for the assembly. Along the length of the bar  40  may also be provided a padding material  38 , whereby this material is softer on the user as it bears into the user when he or she is inverted. 
     Referring now to  FIG. 3 , there is shown a view of a user sitting on the seat  35  of the present invention with the user support bar  40  positioned between the frame sides and the bar over the lap of the user. The upper user support bar  40  and a lower leg support  45  are both telescopically extendable, while the user support bar  40  is rotatable with respect to the seat frame to facilitate comfortable positioning thereof against the user. 
     Referring now to  FIGS. 3 and 4 , the transition between an upright position and an inverted position is illustrated. Once secured by the user support bar  40  and after the arms  42  thereof have been rotated to a position such that the bar  40  is over the lap of the user, he or she is secured against the seat  35 . The user holds on to the curved members  25  of the frame sides in order to remain secured while placing the legs against or behind the leg supports  45 , which are positioned underneath the seat  35 . During the transition to an inverted state, the user slides his or her hands along the curved members  25  such that the inversion is slow and controlled. The seat  35  rotates about its rotational joint  57  between the frame sides and the user slowly inverts. The user can then grasp the inversion handles  65  at the base of the frame sides. While seated and when inverted, the structure of the frame  15  (base members  23 , upstanding members  22 , curved members  25 , seat support plates  60 , and the backrest frame  30 ) remains static and stable as the seat is permitted to rotate and invert the user. 
     To provide relief from a migraine, the user leans forward and rotates the seat forward from its horizontal position until the seat  35  is substantially vertical. In this position, the upper body of the user assumes an inverted position in relation to the frame  15  of the device  10 . The user may then orient his or her head in various positions and perform exercise methods that facilitate a change in blood flow within the head, thereby providing therapeutic relief from the migraine. 
     The frame  15  comprises a plurality of grasping mechanisms that provide a user with locations to enable a user to obtain and/or remain in a desired orientation when rotated forward. The base member  23  of the frame  15  comprises inversion grips  65 , which enable a user to stay in a full inverted position when rotated forward in the seat  35 . Additionally, the curved member  25  comprises padding that facilitates grasping by a user, whereby the curved member  25  and the inversion grips  65  enable a user to remain at differing angles as for some users a full 180 degree inversion angle may not be suggested. 
     Referring now to  FIG. 5 , there is shown a view of the inversion chair of the present invention in a state such that the seat  35  is supported by the user support bar  40  thereunder, whereby the assembly can be deployed as a traditional, upright chair. This view illustrates an alternate embodiment of the present invention, wherein a first and second user support bar clip  50 ′ are located on first and second frame side (either along the curved members  25  or alternatively along the seat support plates  60 ), as opposed to be disposed along the underside of the seat frame. In this configuration, the telescopic members  39  of the user support bar  40  are extended outward such that the ends thereof rest within the clips  50 ′ and the bar  40  is positioned below the seat  35  and between the curved members  25 . As with the first embodiment, the bar  40  is removed from the sockets  44  of the user support arms  42  and placed below the seat  35  to prevent rotation of the same about its joint  57 . 
     In use, an individual may enter the chair by removing the padded support bar  40  from the support bar arms  42 , or may enter the chair if the support bar  40  is positioned within the clips  50 . The user can remove the bar  40  from the clips  50 , then raise the support bar arms  42  from the sides of the seat  35  and secure the support bar  40  within the support bar arms  42  in order to securely position him/herself within the chair and adjust the height and angle of the support bar arms  42 , thereby providing comfort for the user. Thereafter, the user can grasp the pair of curved members  25  to remain securely in place and then safely position his or her feet behind the adjustable footrest  45 . 
     After being secured within the chair  10 , the user may then by grasping the pair of curved members  25  slowly lean forward while advancing their grasp and pulling themselves downward, thereby facilitating the forward rotation of the seat  35  and raises the legs behind the user. Continued advancement along the curved members  25  brings the user into a substantially inverted orientation as displayed in  FIG. 4 . The hands of the user would then be in proximity to the pair of lower inversion grips  65 , whereby the user can hold each of the grips  65  in order to sustain a controlled inverted orientation. 
     While inverted, the user may perform the first set of exercises to increase the blood flow while stretching out all sets of muscles around the head including forehead, upper face, sides and back of the head. After the user is controllably inverted, blood flow should become fairly stable in about ten seconds. Then the user may perform an internal breath retention by first taking a deep breath then holding on to the breath by pushing back the rear part of the tongue on the soft palate to block all the airway passages through the back of the mouth. Then the user may perform a total contraction of the abdominal muscles tightly to push the inhaled air out of the lungs while still blocking all the airways passages. Stay on the pulmonary airflow push up position for bout 5-8 seconds. Then remove the tongue from the soft palate and release the air out through the nostrils and mouth at once and relax the abdominal muscles for about 5-8 seconds while still inverted. This controllable movement can deeply stretch out all the muscles around the head including forehead, upper face, sides and back of the head as well as pumping and circulating the blood and oxygen flow through the vessels in these areas. The first exercise process may be repeated about four times. The user remains stationary in the inverted position at all times during the first exercise method. 
     The user may then let go of the inversion grips  65  and grab onto the curved members  25  and advance his or her grip along the curved members  25 , thereby facilitating the advancement of the user to an upright sitting position as displayed in  FIG. 3 . Then the user removes his or her feet from behind the adjustable footrest  45 . Thereafter, the user may let go of the curved members  25  and then remove the user support bar  40  from the arms  42  and secure the support bar  40  within the clips  50  located underneath the seat  35 . Then the user may lower the first and second support bar arms  42  to the same level as the seat  35 , displayed in  FIG. 2A , and get ready for the second set of exercises. At the upright position the user may seat back and lean the head back against the headrest and remain stationary for about five minutes to allow the concentration of the blood move back from the face as well as the circulation of the blood through the head return back to normal. 
     Then the user may remove the head from the headrest and keep the head straight while seating in an upright position and begin to perform the second set of exercises. The user then may start the second exercise method by holding a pen vertically in front of the face and in contact with the tip of his/her nose. Then the user may keep the eyes wide open and start looking at the connecting point between the pen and the tip of the nose while raising the eyebrows as high as possible and keeping the lips closed. The user may stay in this position and keep the view direction on the same spot at all times in about 20-30 seconds. Then the user may relax by removing the pen away from the face and looking straight ahead at a distant object as well as keeping the eyes in a natural position for about one minute before repeating this process again. This second exercise process may also be repeated about four times. 
     The second exercise method focuses on stretching the muscles of the forehead, temples and upper face (sinus area) which is necessary for the muscle fixation as well as blood vessels circulation adjustment in the forehead and upper face area right after performing the first exercise method. 
     The user may then exit the inversion chair  5  minutes after performing the first and second exercises. 
     Positive results should begin to occur about five minutes after completion of the first and second exercise processes. If however, any signs of migraine pain remain about twenty minutes after performing the first and second sets of exercise methods, the pair of exercises may be repeated until all signs of migraine have subsided.
