Such components or features may optionally be included in some embodiments, or may be excluded.

[0016] Embodiments of the present disclosure include an SCBA including a lumbar cushion cushioning system. In some environments, when the user is wearing the SCBA, the heavy barrel attached to the user's back may move nearby when the user is exercising (eg, when running, walking, bending, kneeling, etc.). The movement of the heavy cylinder may cause problems for the user, which may damage the back of the user. The applicant of the present invention has developed a lumbar cushion cushioning system that can be located at the connection point between the lumbar cushion and the back plate of the SCBA, where the system can be operatively slowed down, or otherwise hinder or affect The movement of the backboard (and cylinder) relative to the lumbar pad (and the user's body).

[0017] Referring now to FIG. 1, a typical SCBA is depicted. The SCBA 100 may include a cylinder 103 operable to contain breathable air. The barrel 103 can be attached to the back plate 102, and the back plate 102 can be put on to hold the barrel 103 in place on the back of the user. The back plate 102 can be attached to a waist pad 104 and a shoulder pad (or strap) 105, which can in turn operably hold the barrel 103 in place on the user's back. When the user is exercising, the back plate 102, the waist pad 104, and the shoulder pad 105 can stabilize the cylinder 103. The waist pad 104 can be fitted around the waist of the user, while the shoulder pad 105 can be fitted on the users shoulders and above the chest, and the waist pad 104 and the shoulder pad 105 can be attached to more than one Location. The SCBA 100 may also include a mask 101 that is operatively attached to or above the user's face to provide breathable air from the cylinder 103 to the user. In addition, as understood by those skilled in the art, the barrel 103 may be attached to a pressure reducer (pressure reducer) 106.

[0018] Referring to FIG. 2, a lumbar cushion cushioning system 200 is depicted. Figure 2 shows a cut-away side view of the waist pad 204 and back panel 202 of the SCBA (as shown in Figure 1, similar to the waist pad 104 and back panel 102). Screws 206 and nuts 208 can be used to fix the lumbar pad 204 relative to the back plate 202. In some embodiments, the lumbar pad 204 may be attached to the back panel 202 in a loose, movable manner. In other words, the screw 206 and the nut 208 can loosely hold the lumbar pad 204 in a state of abutting the back plate 202.

[0019] In some embodiments, the lumbar cushion cushioning system 200 may include a soft rubber liner 220 located between the lumbar cushion 204 and the back plate 202, wherein the soft rubber liner 220 can be operatively compressed to slow down the back plate Movement relative to the lumbar pad. For example, when the back plate 202 moves toward the waist pad 204, the soft rubber pad 220 can be compressed, and when the back plate 202 moves away from the waist pad 204, the soft rubber pad 220 can be less compressed. This can slow down any strong movement of the backplate 202 relative to the lumbar pad 204, which can be harmful to the user's back. In some embodiments, the lumbar pad 204 can swing or swing around the screw 206 relative to the back plate 202, as represented by the arrow 240, which may be a problem for the user when bending, kneeling, or moving in another way advantageous.

The movement of the backplate 202 relative to the lumbar pad 204 represented by the arrow 240 may allow the backplate to move to or into a more comfortable position relative to the lumbar pad 204 when the user bends or exercises. When the user returns to the upright position after bending, kneeling, etc., the back plate 202 can move relative to the lumbar pad 204 to return to the original upright position. The soft rubber pad 220 can be used to slow down this movement, thereby allowing smooth movement and avoiding strong movement between the back plate 202 and the lumbar pad 204.

[0020] In some embodiments, the soft rubber pad 220 may fit around the portion 234 of the waist pad 204 and/or within the recess in the waist pad 204. The soft rubber gasket 220 may also be in contact with the portion 222 of the back plate 202. In some embodiments, the soft rubber liner 220 may include an opening operably attached to the portion 234 of the waist pad 204 and the screw 206, wherein the soft rubber liner 220 may not hinder the attachment of the waist pad 204 to the back plate 202 . In some embodiments, the soft rubber liner 220 may have a Shore hardness of about 30-40.

[0021] In some embodiments, the lumbar cushion cushioning system 200 may include a hard rubber liner 230 located between the lumbar cushion 204 and the back plate 202, wherein the rubber liner 230 can be operatively compressed to slow down the back plate relative to Movement of the lumbar pad. For example, when the back panel 202 is twisted relative to the lumbar pad 204, the hard rubber pad 230 may compress and/or decompress. This may allow movement between the back plate 202 and the lumbar pad 204, which may be beneficial to the user when bending, kneeling, etc. The hard rubber pad 230 can also slow down any strong movement of the back plate 202 relative to the waist pad 204, which can be harmful to the user's back. The hard rubber pad 230 can allow the back plate 202 and the waist pad 204 to be Smooth movement between. In some embodiments, the hard rubber liner 230 may fit around the portion 232 of the back plate 202 and/or in a recess in the back plate 202. The hard rubber pad 230 may also be in contact with the portion 234 of the waist pad 204. In some embodiments, the hard rubber liner 230 may include an opening operably attached to the portion 232 of the back plate 202 and the screw 206, wherein the hard rubber liner 230 may not hinder the attachment of the lumbar cushion 204 to the back plate 202. catch. In some embodiments, the hard rubber liner 230 may have a Shore hardness of about 50 to 65.

[0022] In some embodiments, the lumbar pad cushioning system 200 may include one or more magnets 214 on the lumbar pad 204 and one or more magnets 210 on the back plate 202. The magnet 210 on the backplate 202 can operably interact with the magnet 214 on the lumbar pad 204 to slow down any movement of the backplate 202 relative to the lumbar pad 204. For example, the magnet 214 of the waist pad 204 and the magnet 210 of the back plate 202 may have the same polarization and therefore may repel each other, especially when they are very close to each other. This can slow down any strong movement of the backplate 202 relative to the lumbar pad 204, which can be harmful to the user's back. In addition, as indicated by the arrow 240, the lumbar pad 204 can swing or swing around the screw 206 relative to the back plate 202, which may be harmful to the user's back. In some embodiments, magnets 210 and 214 may be used to slow this movement.

[0023] In some embodiments, the magnet 214 may be located in the recess 216 of the waist pad 204. In addition, the magnet 210 may be located in the recess 212 of the back plate 202. The magnets 214 and 210 may be positioned such that each magnet 214 of the waist pad 204 corresponds to the magnet 210 of the back plate 202 as shown in FIG. 2. In the embodiment shown in Figure 2 (and subsequent figures), these magnets may include six pairs of magnets, six of which are on the waist pad and six of the magnets are on the back plate, and three of which are Above the screw and the three pairs of magnets are below the screw. However, any number of magnets can be used to provide the same cushioning performance.

[0024] Referring now to FIG. 3, another view of the lumbar pad cushioning system 200 of FIG. 2 is shown. In FIG. 3, the lumbar pad 204 is cut away to show the other elements of the system 200. In FIG. 3, the soft rubber pad 220 is shown as being attached to the periphery of the portion 234 (not shown) of the waist pad 204. In some embodiments, the shape of the soft rubber liner 220 may also be designed to avoid any interference with the magnet 210 and/or 214 (not shown). In addition, the hard rubber liner 230 is illustrated as being attached around the portion 232 of the back plate 202 and inside the portion 234 of the waist pad 204, where the hard rubber liner 230 can be combined with the portion 232 of the back plate 202 and the waist pad 204. Part 234 interacts with each other. In some embodiments, as indicated by the arrow 242, the lumbar pad 204 can be twisted around the screw 206 relative to the back plate 202, which may be beneficial to the user when bending, kneeling, or moving in another way of. The movement of the back plate 202 with respect to the lumbar pad 204 represented by the arrow 240 may allow the back plate to be relative to the lumbar pad 204 when the user bends or moves.

The lumbar pad 204 moves to or enters a more comfortable position. When the user returns to the upright position after bending, kneeling, etc., the back plate 202 can move relative to the lumbar pad 204 to return to the original upright position. This movement can be slowed by the hard rubber pad 230, allowing smooth movement and avoiding strong movement between the backplate 202 and the lumbar pad 204.

[0025] Referring now to FIG. 4, an exploded view of the lumbar cushion cushioning system 200 is shown. The system includes a back plate 202, a lumbar pad 204, a screw 206 and a nut 208, magnets 210 and 214, a soft rubber liner 220, and a hard rubber liner 230, as described above.
