Back support frame

BACK SUPPORT FRAME

FIELD OF THE INVENTION

[0001] The instant disclosure relates generally to self-contained breathing apparatus (“SCBA”) systems, and more particularly to a back support frame for use in such SCBA apparatus systems.

BACKGROUND OF THE INVENTION

[0002] Self-Contained Breathing Apparatus (“SCBA”), which are utilized in the fire service industry typically consists of one SCBA frame/hamess and a generally vertically oriented air bottle that is strapped onto the firefighters back and worn over his/her canvas turnouts. The standard SCBA design is somewhat similar to a standard SCUBA tank design. However, there is an obvious difference in the environment where these frames are used that impact users of the SCBA and the SCUBA frames. For example, while using a SCUBA tank, the human body is buoyant and is not subject to the stresses of gravity outside of water. However, when a firefighter uses a SCBA, the conditions and stresses on the firefighter can cause significant duress and injury.

[0003] Consistent use of the standard SCBA configuration can cause significant wear on the users back and spine. Specifically, injuries to the L4-L5 and L5-S1 have been reported with some frequency and can require surgery, which immobilize the firefighter and removes them from service. Presently, the standard SCBA restricts movement along the spine causing the lower back to function as the only hinge and fulcrum for movement, thus placing all the stress of the torso on the lower spine.

[0071] Future developments in technology may present an opportunity for improvements in the design of the frame 100. The SCBA bottle utilized for this design was a 3000-psi bottle with overall dimensions of 4 3/8 inches in diameter and 16 inches long including the knob and gauge. The actual bottle was 13 inches long. The number of mounting plates 102 as presented is 4 plates for the SCBA frame 100 and also 4 plates for the other applications noted. The overall dimensions of the entire frame as well as the size and number of

Date Reçue/Date Received 2022-03-17 mounting plates 102 may also change. There may be as few as 3 mounting plates 102 and as many that can fit along the length of the pack, as the width of each plate may be manufactured narrower in the future. The key is that the SCBA frame 100 facilitates increased movement of the spine by that off additional points of movement over the present rigid frame designs that are currently utilized. The SCBA frame 100 design allows for the points of movement by that of the cable system attachment mechanism 104. Hinges, Ball joints, springs, and any other material that will form a joint are contemplated and may be suitable for use. The cable system/attachment mechanism 104 allows for a move versatile joint that allows 360 degrees of movement and is of heavy enough gauge material to support axial loading of the pack and allows some “give” in not only the vertical axial loading but also lateral axial stresses. The cable system/attachment mechanism 104 may be centrally located or located at the ends of the mounting plates 102. As shown in Figures 8A-8C, the user is allowed much more freedom of movement utilizing the SCBA frame 100 design. The SCBA frame 100 design moves with the user’s back rather than being limited.

[0072] Although SCBA frame 100 design was initiated with respect to firefighting equipment it should be understood that this SCBA frame 100 design may benefit other people outside the Fire Service. As shown in Figure 9, a mobility frame 200 may comprise any type of back frame utilized for hiking, hunting, back packing or even military operations can be improved with this concept of the Advance Spinal Mobility Frame. With some minor modifications, this mobility frame 200 design is fully applicable for a Back-Pack application.

Date Reçue/Date Received 2022-03-17

[0073] The mobility frame 200 may comprise multiple generally rectangular mounting plates 202 that are coupled by attachment mechanisms 104. In one embodiment, the mobility frame 200 comprises four generally rectangular mounting plates 202 that are coupled by attachment mechanisms 104. The attachment mechanism 104 allows the mounting plates 202 to move relative to one another and allows the SCBA frame 100 to conform to the shape of the user’s back. The attachment mechanism 104 may allow the user to move along vertically, horizontally, and torsionally.

[0074] The mounting plates 202 are similar to mounting plates 102 of but the SCBA air cylinder attachment system 186 have been removed. The mount plates 202 allow points (slot, cutouts, etc.) for securing the material and webbing that makes up the various back packs in the industry and it’s done. The cable system/attachment mechanism 104 may be centrally located or located at the ends of the individual mounting plates 202. The orientation of the cable system/attachment mechanism 104 and the mounting plates 202 would be the same regardless of whether the mobility frame 200 does or does not include the SCBA air cylinder attachment system 186.

[0075] The width of the mobility frame 200 can be reduced to whatever the need of the pack manufacturing company may require. Many frames of the traditional one-piece vertical back pack frames are approximately 8 inches by 26 inches. The cable system/attachment mechanism 104, slots and punch outs along with the lumbar attachments will not change.

[0076] Referring now to Figures 10-11, in various embodiments, an SCBA frame 300 that conforms with the user’s spine but also utilizes a conventional SCBA bottle 302 in a vertical orientation. The SCBA frame 300 complies with all of the requirements discussed

Date Reçue/Date Received 2022-03-17 above in paragraphs 41-45 and is fabricated from the same material discussed above. The SCBA frame 300 also incorporates all of the functionality of the other embodiments discussed above.

[0077] In various embodiments, the SCBA frame 300 is similar to the SCBA frame discussed above but includes a bottle attachment system 304 for utilizing a conventional vertical SCBA bottle 302. In various embodiments, SCBA frame 300 may comprise multiple generally rectangular mounting plates 306 that are coupled by attachment mechanisms 308. The attachment mechanism 308 are similar to the attachment mechanisms 104 discussed above. In one embodiment, the SCBA frame 300 comprises three generally rectangular mounting plates 306 that are coupled by attachment mechanisms 308. As discussed above, the attachment mechanisms 308 allow the mounting plates 306 to move relative to one another and allows the SCBA frame 300 to conform to the shape of the user’s back. The attachment mechanism 308 may allow the user to move along vertically, horizontally, and torsionally.

[0078] The mounting plates 306 will each be positioned to run horizontal and perpendicular to the spine and lay across the back from left to right. These mounting plates 306 are distinct and separate and coupled together via the attachment mechanisms 308. As shown in Figure 11, the bottle 302 may then be attached to the SCBA frame 300 by the bottle attachment system 304.
