Since the seat assembly 20, leg assembly 22, back assembly 18 are rotatable at the plurality of angles with respect to the angled surface 16, the chair A may be rotatably positioned on the angled surface 16 in order to position the body 102 of the seat 24 and the arms 108, 110 in a substantially horizontal position with respect to the angled surface 16.
  • [0042]
    Turning to FIG. 4 and referring to FIGS. 1-3, the chair A is configured to fold between the collapsed position 14 and the expanded position 12. In the collapsed position 14, the foot assembly 28 folds along the foot hinge 126 toward the leg assembly 22 such that the foot side members 130 fold inside the leg side members 90 of the leg assembly 22. Since the foot assembly 28 is rotatable around the foot hinge 126, at a plurality of angles, the first foot ends 132 rotate upward and toward the first leg ends 92. Since the foot side members 130 are shorter in size than the leg side members 90, the foot assembly 28 easily fits within the seat assembly 20. Once the foot assembly 28 has rotated into the leg assembly 22, the leg assembly 22 rotates around the leg hinge 86 and folds inside the seat assembly 20. Since the leg assembly 22 is rotatable around the leg hinge 86 at a plurality of angles, the second leg ends 94 rotate upward and toward the second seat ends 66 in order to fold within the seat side members 60. Since the leg side members 90 are smaller in size than the seat side members 60, the leg assembly 22 easily fits within the seat assembly 20.
  • [0043]
    Additionally, the seat assembly 20 rotates within the back assembly 18. Since the seat assembly 20 rotates around the seat hinge 54 at the plurality of angles, the first seat ends 64 rotate toward the first back ends 38 of the back frame 32. Since the seat side members 60 are shorter in length than the back side members 36, the seat assembly 20 easily fits within the back assembly 18. As such, the foot assembly 28, leg assembly 22, seat assembly 20 and back assembly 18 are aligned and folded to provide a convenient and collapsible carrying position for the user. Furthermore, the back side members 36 are longer than the seat side members 60 to extend the handle aperture 52 of the back covering 34 beyond the folded foot assembly 28, leg assembly 22, and seat assembly 20 to provide a convenient access for the user to carry the chair A in the collapsed position 14.
  • [0044]
    Turning to FIGS. 5A-5C and referring to FIGS. 1-4, during use, the person unfolds the chair A from the collapsed position 14 to the expanded position 12 and positions the chair A on the surface, which may be angled with respect to the horizon. The user conveniently carries the chair A via the handle aperture 52 and places the chair on the angled surface 16 in the collapsed position 14. The user then unfolds the seat assembly 20 from the back assembly 18 by moving the seat assembly 20 along the seat hinge 54. The user anchors the back assembly 18 into the angled surface 16, i.e., the ground by stepping on either of the crossbars B in order to drive the anchors 30 into the angled surface 16. The user levels the first arm 108 and second arm 110 and locks the first arm 108 and the second arm 110 with the first arm track 114 and the second arm track 116.
  • [0045]
    While unfolding the seat assembly 20, the user engages the adjustment pin 104 of the collapsible seat 24 with at least one of the plurality of seat adjustment positions 72 of the seat track 70. The user, meanwhile, engages the engagement pins 115 of the first arm 108 and the second arm 110 with a one of the plurality of arm positions 118 of the first arm track 114 and engages the connection pins 112 with one of the plurality of arm positions 117 of the second seat track 116. The arms 108, 110 are strong enough to connect and to support the back assembly 18 and the seat assembly 20. In other words, the arms 108, 110 lock the frames of the back assembly 18 and seat assembly 20 into place. Additionally, the user can rotate the adjustment pin 104 to obtain the desired tension of the seat 24. In positioning the adjustment pin 104 in the desired seat adjustment position, the user can position the body 102 of the seat substantially horizontal in the extended position while the chair A is positioned on the angled surface 16.
  • [0046]
    The user then rotates the leg assembly 22 from inside the seat assembly 20 by rotating the leg assembly 22 around the leg hinge. The user then unfolds the foot assembly 28 via the foot hinge 126 from inside the leg assembly 22 to a desired angled position and locks the foot assembly 28 in that desired position via the foot hinge 126. In rotating the leg hinge 86 in the plurality of angles, the user moves the second leg ends in contact with the angled surface 16. In moving the seat assembly 20 through the plurality of angles via the seat hinge 54, the second seat ends 66 contact the angled surface 16. Depending upon the angle of the surface, the user can easily adjust the angle of the foot assembly 28, leg assembly 22, seat assembly 20 and back assembly 18 through the respective hinges to accommodate the desired position of the foot assembly 28, leg assembly 22, seat assembly 20 and back assembly 18.
  • [0047]
    Turning to FIG. 5A, on a substantially flat surface, the user positions the adjustment pin 104 in the lower most channel member 76 of the seat track 70 to provide the substantially horizontal position. As the surface angles, however, the user conveniently moves the adjustment pin 104 to the appropriate channel member 76 of the seat track 70 to maintain the body 102 of the collapsible seat in the substantially horizontal position. The user also conveniently moves the engagement pins 115 along the slot 120 to the opposite channel 122 and moves the connection pins 112 along the slot 119 to the appropriate channel 121 to maintain the arms 108, 110 in the substantially horizontal position. For example, in FIG. 5B, the surface angles at approximately 45 degrees. The user conveniently moves the adjustment pin 104 to the appropriate channel member 76 of the seat track 70 to maintain the body 102 of the collapsible seat in the substantially horizontal position. The user also conveniently moves the engagement pins 115 along the slot 120 to the opposite channel 122 and moves the connection pins 112 along the slot 119 to the appropriate channel 121 to maintain the arms 108, 110 in the substantially horizontal position. Still further, in FIG. 5C, the surface angles at approximately 60 degrees. The user conveniently moves the adjustment pin 104 to the appropriate channel member 76 of the seat track 70 to maintain the body 102 of the collapsible seat in the substantially horizontal position. The user also conveniently moves the engagement pins 115 along the slot 120 to the opposite channel 122 and moves the connection pins 112 along the slot 119 to the appropriate channel 121 to maintain the arms 108, 110 in the substantially horizontal position.
  • [0048]
    As such, the user can engage the first arm 108 and the second arm 110 into with at least one of the plurality of arm adjustment positions 118, 117 of the arm track 114, 116 to maintain the first arm 108 and second arm 110 in the substantially horizontal position with respect to any of the angled surfaces 16. To engage the appropriate arm adjustment position 117, the user pulls or “pops” the arms 108, 110 away from the connection pins 112, moves the connection pins 112 within the slots 119 and pushes the arms 108, 110 back toward the connection pins 112 to connect the connection, pins 112 into the appropriate channels 121. Furthermore, the user may stabilize the chair A to the angled surface 16 by penetrating the anchors into the surface. In this expanded position 12, the seat adjustment pin 104 is positioned in its desired channel member 76 of the seat track 70 wherein in this position the seat adjustment pin 104 is positioned behind the front face 46 of the back covering 34. As such, when the person sits in the body 102 of the seat, the person does not directly contact the adjustment pin 104, but instead, contacts the back covering 34. Furthermore, the user adjusts the tension of the collapsible seat by rotating the adjustment pin 104, which, in turn, wraps the crimped end of the seat around the adjustment pin 104.

Still further, the panel 162 may include an overlapping curtain in front of the chair A to allow entry and exit of the chair A. During nonuse of the chair A, a zippered bag 180 contains the panel 162. As shown in FIG. 7, the zippered bag 180 attaches to the back of the chair A for convenient and unobtrusive storage of the panel 162.
  • [0053]
    Returning to FIG. 8, a plurality of removable fasteners 182 fastens the panel 162 to the flexible members 160. The removable fasteners 182 may include but are not limited to clips or hook and loop fasteners. Alternatively, the removable fasteners 182 may include eyelets attached to the panel 162 wherein the eyelets are sized and shaped to accept the flexible members 160.
  • [0054]
    Prior to or subsequently after engaging the panel 162 to the flexible members 160, at least one stabilizing rod 184 removably connects with each flexible member 160 when the flexible members 160 are in the expanded position 176. The stabilizing rod 184 may adjust in the middle to support the flexible members 160 and to keep the flexible members 160 parallel to each other in the expanded position 176. Multiple stabilizing rods 184 may be positioned between the lengths of the flexible members 160 to provide uniform spacing and support of the flexible members 160.
  • [0055]
    As shown in FIG. 9, the stabilizing rod 184 has ends with apertures defined therethrough. The flexible members 160 extend through these apertures such that the stabilizing rod slides along the flexible members 160 as the flexible members 160 are pulled out of the channel 156. A plurality of stabilizing rods 184 may slide along the flexible members 160. In one embodiment, the cross member 166 includes a cavity (not shown) which stores the stabilizing rod 184 when the cross member 166 removeably connects with the back assembly 150 in the retracted position 174. Accordingly, the second ends 170 of the flexible members 160 extend through the apertures of the stabilizing rod 184 and connect with the cross member 166. In one embodiment, the cavity is sized and shaped to store the plurality of stabilizing rods 184.
  • [0056]
    Each bias member 164 has an upper end 183 and a lower end 185. The upper ends 183 are connected near the second ends 170 of the flexible members 160 and the lower ends 185 are connected near the chair A. In one embodiment, the bias members 164 comprise cords such as nylon cords. In another embodiment, the bias members 164 comprise the flexible rods. The bias members 164 pull the second ends 170 of the flexible members 160 toward the chair A to bend the flexible members 160 in an arc shape 188 over the chair A so that the flexible members 160 cover the chair A.
  • [0057]
    Since the flexible members 160 are bendable and the stabilizing rod 184 supports the flexible members 160, the arc 188 formed by the flexible members 160 is adjustable in size. The size of the adjustable arc 188 depends on the amount of tension the bias members 164 apply to the second ends 170 of the flexible members 160. Accordingly, the bias members 164 may size the arc 188 of the flexible members 160 such that the second ends 170 of the flexible members 160 position the top of the panel 162 at a height to allow the user to stand in a full upright position in front of the chair A. The bias members 164 may also size the arc 188 such that the second ends 170 of the flexible member position the top of the panel 162 at a height just above the user's head. As such, this size of the arc 188 and height of the panel 162 minimize any blockage of view from behind the chair A.
  • [0058]
    To assist in pulling the flexible members 160 out of the back assembly 150 and into the expanded position 176, the cross member 166 attaches with each second end 170 of each flexible member 160 (FIG. 9). Additionally, as shown in FIG. 7, the cross member 166 removably attaches to the back assembly 150 of the chair A when the flexible members 160 are positioned in the retracted position 174. As shown in FIG. 8, the upper ends 183 of the bias members 164 removably connect to the cross member 166 when the flexible members 160 are positioned in the expanded position 176. As shown in FIGS. 7 and 8, the canopy further comprises a retractable assembly 186 (FIGS. 7 and 8) that connects to each lower end 185 of the bias members 164. The retractable assembly 186 has a coiled rewind member that rewinds the bias members 164 when the bias members 164 disconnect from the cross member 166.
