Description

RESPIRATORY COMPONENT MOUNTING ASSEMBLY BACKGROUND OF THE INVENTION The present invention relates to a respiratory protection system. In particular, the invention concerns a waist-mounted respiratory component system including a mounting assembly for attaching a respiratory component to a belt. Fan-forced positive pressure breathing apparatus, commonly known as Powered Air Purifying Respirators (PAPRs), and other respiratory components are used by first responders (HazMat, police, fire, and civil defense), military or other emergency response units to manage hazardous respiratory exposure. These respirators are generally used in industrial applications where the environmental hazards are well defined and quantified. Respiratory hazards might include harmful gases, vapors, and particulate matter. Respirators include a breathing mask, or other suitable hood, helmet or headtop, having a filtered air inlet. Respirators are employed to continually supply positive pressure to the wearer's mask. The filtered supplied air replenishes the internal confines of the mask and is continually ejected. Currently, respiratory components are typically attached to a belt by threading the belt through slots in the housing of the respiratory component. The responder wears the belt carrying the respiratory components around his or her waist and the load is normally attached to the rear of the belt. In addition to carrying the respiratory component, the responder also wears or carries additional equipment, such as a hood, protective clothing, and protective footwear, some of which is also attached to the belt. The attachment mechanism for securing the respiratory components to the belt should prevent the respiratory component from falling off the belt if caught on machinery or other apparatus while in use. In addition, the attachment mechanism should facilitate ease of attachment and detachment of the respiratory component to and from the belt. Current belt configurations and component attachment to those belts induce inefficient and cumbersome interchange of respiratory components carried by the belt. In order to remove a component and/or add a new component, the belt must be removed. The respirators and associated components of the respiratory component system are generally exposed to hazardous environments, which cause contamination to those components, including any related attachment mechanisms for securing the respiratory components to the belt. Discarding contaminated equipment is costly and not desirable. Therefore, responders would prefer respiratory components and attachment mechanisms that may be decontaminated after each use, and then reused. There exists a need for a waist-mounted respiratory protection system that is decontaminatible, and in particular, mounting assemblies for attaching respiratory components to a system belt. The mounting assemblies should be strong enough to secure the respiratory components to the belt without risk of the components falling off during use. In addition, the mounting assemblies should facilitate efficient attachment and detachment of a variety respiratory components. BRIEF SUMMARY OF THE INVENTION The present invention is directed to a respiratory component mounting assembly including a first respiratory component, a second respiratory component and a mounting clip. Each of the first and second respiratory components includes at least two spaced apart clip openings. The mounting clip has an intermediate portion and two spaced apart free ends connected to the mtermediate portion. The intermediate portion of the mounting clip is received within both of the clip openings of the first respiratory component and the free ends of the mounting clip are received in the clip openings of the second respiratory component for releasably securing the first and second respiratory components together. The present invention is also directed to a method for mounting a respiratory component to a user- wearable respiratory component support member. The method includes providing at least two spaced apart connector receptacles on the respiratory component, providing at least two slots in the support member, and providing a mounting clip having an intermediate portion and two spaced apart free ends projecting therefrom. The intermediate portion of the mounting clip is inserted into the slots on the support member, with the free ends of the mounting clip projecting from one side of the support member. The free ends of the mounting clip are inserted into the connector receptacles on the respiratory component. In a further embodiment of the inventive method, the intermediate portion of the mounting clip is inserted into the clip openings on the respiratory component, with the free ends of the mounting clip projecting from one side of the respiratory component. The free ends of the mounting clip are then inserted into the slots of the support member.

While the above-identified drawing figures set forth several embodiments of the invention, other embodiments are also contemplated, as noted in the discussion. In all cases, this disclosure presents the present invention by way of representation and not limitation. It should be understood that numerous other modifications and embodiments can be devised by those skilled in the art which fall within the scope and spirit of the principles of this invention. DETAILED DESCRIPTION A respiratory protection system worn by a user is shown in FIG. 1. The respiratory protection system includes a breathing face-piece 10, or head gear, and a respiratory component 12, such as a fan-forced positive pressure breathing device, commonly known as a Powered Air Purifying Respirator (PAPR), an air filter or some other component device which may be used in a respiratory system, such as an air quality monitor. An air hose or tube 14, connects the respiratory component 12 to the breathing face-piece 10 to supply breathable air to a user 16. The respiratory component 12 is designed to be worn by a user working an atmosphere with unwanted contaminants, including respiratory hazards. The PAPR 12 has a housing 12a and one or more filter units 12b, which serve to filter unwanted contaminants from the surrounding atmosphere, thus allowing a user wearing the PAPR to work in contaminated or hazardous areas. One example of a PAPR is disclosed and described in U.S. Patent No. 6,575,165, entitled "Apparatus and Method for Breathing Apparatus Component Coupling." The present invention concerns a respiratory component mounting assembly 18
(shown in FIG. 2) for attaching the respiratory component to a belt 20, which is a user- wearable respiratory component support member. The belt 20 may be used with a variety of respiratory components 12 for hands- free use in contaminated areas. The respiratory component 12 is attached to the belt 20 for carrying by the user 16 and positioned such that the load is carried at the rear of the belt 20. The respiratory component 12 attached to the belt 20 allows carriage by the user 16 of the respiratory component 12 with the hands left free for other purposes. In addition, the belt 16 is configured to provide an anatomical fit wherein the hips carry the load of the respiratory component 12, leg movement is freed, and the lumbar of the back is firmly supported. The belt 20 also cushions the back of the user 16 while still maintaining rigidity to support the respiratory component 12. Line 22 represents the curvature of a user's spine. The respiratory component 12 is formed from a decontaminatible material such that after use in hazardous areas, the belt 20 may be decontaminated for future reuse. FIG. 2 is an exploded perspective view of a waist-mounted respiratory component system 24. The waist-mounted respiratory component system 24 includes the belt 20, the mounting assembly 18 for mounting the respiratory component 12 to the belt 20, and the respiratory component 12. The mounting assembly 18 includes an intermediate portion 26 and two spaced apart free ends 28, 30 connected to the intermediate portion 26. The belt 20 includes spaced apart mounting slots 32, or clip openings, for attaching the mounting assembly 18 to the belt 20. The mounting slots 32 receive the intermediate portion 26 of the mounting assembly 18, for example, the mounting assembly 18 is woven through the mounting slots 32 of the belt 20. The respiratory component 12 includes two spaced apart openings, 34, 36 or connector receptacles, that receive the free ends 28, 30 of the mounting assembly 18 for releasably securing the respiratory component 12 to the belt 20. In further embodiments of the respiratory component system 24, the mounting slots 32 of the belt receive the free ends 28, 30 of the mounting assembly 18 and the openings 34, 36 of the respiratory component 12 receive the mtermediate portion 26 of the mounting assembly 18. Although the mounting slots 32 and clip openings 34, 36 shown in FIG. 2 are generally parallel and vertically aligned, those skilled in the art will recognize that other configurations and orientations for the slots and openings are possible. U.S. Patent Application No. 10/748,907, entitled "Anatomically Fitted Respiratory Component Belt" (attorney docket number 59130US002) and filed on 30 December, 2003, discusses the belt 18 in further detail and is incorporated herein by reference. FIGS. 3-5 show an embodiment of the respiratory protection system belt 20. FIG. 3 provides a perspective view of the belt 20, while FIG. 4 is a front perspective view of the belt 20 and FIG. 5 is a cross-sectional view of the belt 20 taken along lines 5 — 5 of FIG. 4. The belt 20 for carrying one or more respiratory components 12 includes a main belt portion 38, which extends around the back and sides of a user, and a belt buckle portion 40, which extends across a front of a user. The main belt portion 38 includes a back section 42, a left side section 44, a left connective section 46 between the back section 42 and the left side section 44, a right side section 48 and a right connective section 50 between the back section 42 and the right side section 48. The main belt portion 38 includes an outer face 52 and an inner face 54. The back section 42 is wider than the other sections of the main belt portion 38. The left and right side sections 44, 48 and the left and right connective sections 46, 50 are symmetrically shaped relative to the back section 42. The back section 42 includes two sets of mounting slots, each comprised of three slots 32. Those skilled in the art will recognize that further embodiments of the belt may include fewer or more mounting slot sets comprised of fewer or more slots. The slots 32 are used for mounting the respiratory component 12 to the belt 20, and in particular, for receiving the mounting assembly 18. The main belt portion 38 includes connector elements 56 for use in mounting additional supportive or respiratory components to the belt 20. In use, the main belt portion 38 has a substantially conical shape such that the belt 20 secures around a user's pelvic girdle and aligns the respiratory component 12 thereon over the lumbar region of a user' s spine. The belt 20 distributes the weight of the respiratory component 12 around a user's pelvis such that a user's hips carry the load of the respiratory component 12. h addition, the shape and the position of the main belt portion 38 allows free leg movement of the user and minimizes pinching adjacent a user's iliac crests during such movement. The position of the main belt portion 38 with respect to a user's spine shifts the rotational momentum of the weight of the respirator component 12 to the user. Overall, the shape of the main belt portion 38 of the belt 20 facilitates positioning of the respiratory component 12, while the belt 20 is worn by a user, over a user's lumbar region at an angle of inclination to enhance comfort of a user. The belt buckle portion 40 of the belt 20 includes a left piece 58 connected to the left side section 44 of the main belt portion 38 and a right piece 60 connected to the right side section 48 of the main belt portion 38. Each piece 58, 60 of the belt buckle portion 40 is adjustable in length, although in further embodiments of the belt 20 only one piece may be adjustable. Free ends of the left and right pieces are selectively connected together by a buckle 62, such as a releasable buckle, or any other buckle known in the art. hi one embodiment, first ends 64, 66 of the left and right pieces 58, 60 of the belt buckle portion 40 are fixedly connected (for example, by stitching or adhesive) to the main belt portion 38. Alternatively, first ends 64, 66 may be detachably connected to the respective left and right side sections 44, 48. In this case, each side section 44, 48 includes an opening 68, 70 for receiving the first end of the respective belt piece and the first end of each belt piece includes a hinged connective member 72, 74. To attach or release either belt piece 58, 60 from the main belt portion 38, the connective member 72, 74 folds at its hinge to narrow the connective member 72, 74 to facilitate sliding of the connective member 72, 74 through the opening 68, 70 of the side section 44,48. In an attached position, the connective member 72, 74 is unfolded at the hinge such that the connective member 72, 74 is wider than the opening 68, 70 to prevent removal of the belt piece 58, 60 from the main belt portion 38. Those skilled in the art will recognize that there are other possible means for releasably connecting belt buckle portion 40 to main belt portion 38. As shown in FIG. 5, the main belt portion 38 has an outer layer 76 and an inner layer 78. The outer layer 76 provides rigidity and the inner layer 78, which contacts a user's body, provides a cushioning layer. The slots 32 in the back section 42 of the main belt portion 38 are reinforced with a reinforcement member 80, such as a plate. The reinforcement member 80 stabilizes the respiratory component 12 and prevents separation of the respiratory component 12 and the mounting assembly 18 or the belt 20, and movement of the respiratory component away from the belt 20. Both the outer layer 76 and the inner layer 78 of the main belt portion 38 are formed from an ethyl vinyl acetate (ENA) co-polymer with a polyolefin elastomer. One suitable ENA is made by Alveo (a Sekisui Company of Luzern, Switzerland). The outer layer 76 ENA has a density of about 125 kg/m3 and the inner layer 78 ENA has a density of about 70 kg/m3 to about 75 kg/m3. Thereby the outer layer 76 is more rigid than the inner layer 78 to form a rigid support piece, whereas the inner layer 78 is less rigid to provide more comfort to a user. The reinforcement member 80 is formed from a low density polyethylene such as made by NTS Plastics (Liverpool, UK). The belt buckle portion 40 is formed from a polyester coated with polyurethane or PNC, which allows the belt buckle portion 40 to be wiped clean. FIGS. 6-9 further illustrate one embodiment of the inventive mounting assembly 18, a mounting clip, shown in FIG. 2, for attaching the respiratory component 12 to the belt 20. The mounting clip 18 includes the intermediate portion 26 and two spaced apart free ends 28, 30 connected to the intermediate portion 26. The intermediate portion 26 extends between a first shoulder 82 and a second shoulder 84, while the first and second free ends 28, 30 extend from the first and second shoulders 82, 84, respectively. The free ends 28,30 are aligned to extend in generally opposite directions. The mounting clip 18 has a first surface 86 and a second surface 88. The first surface 86 of the intermediate portion 26 defines a channel 90 extending between a first outer wall 92 and a second outer wall 94. The channel 90 includes a stepped portion 96 extending towards the first surface 86 and defining a second channel 98 on the second surface 88 of the mounting clip 18. A depth of the first channel 90 (defined by walls 92 and 94) is greater than a depth of the second channel 98 (defined by walls 98a and 98b). The first and second free ends 28, 30 of the mounting clip 18 include first and second biased detent tabs 100, 102 extending generally downwardly and inwardly from the second surface 88 of the mounting clip 18. FIG. 9 is a schematic cross-sectional view of the waist-mounted respiratory component system 24, taken along line A— A of FIG. 4, showing the respiratory component mounting clip 18 and the respiratory component 12 mounted to the belt 20. An example of a suitable respiratory component for use with the mounting clip 18 is JUPITER brand respirator from 3M Company of St. Paul, MN. The intermediate portion 26 of the clip 18 is woven through the mounting slots 32 of the belt 20, whereby the free ends 28, 30 project from the inner face 54 of the belt 20. In the embodiment shown in FIG. 9, four of the mounting slots 32b, 32c, 32d and 32e receive walls 92, 98a, 98b and 94, respectively, of the intermediate portion 26 of the clip 18. Between each adjacent mounting slot 32b, 32c, 32d and 32e, one of the two faces (86, 88) of the clip 18 aligns against either the outer face 52 or the inner face 54 of the belt 20. The respiratory component 12 includes first and second openings 34, 36 for removably receiving the free ends 28, 30 of the clip. The respiratory component 12 also includes first and second opposed detent surfaces 104, 106 adjacent the first and second clip openings 34, 36, respectively. The openings 34, 36 of the respiratory component 12 receive the free ends 28, 30 of the clip 18 whereby the detent tabs 100, 102 of the clip 18 form a locking engagement with the detent surfaces 104, 106 of the respiratory component 12, as seen in FIG. 9. The mounting assembly 18 firmly secures the respiratory component 12 to the belt 20 and prevents the respiratory component 12 from falling off the belt 20 during normal use, and provides strong enough attachment to prevent separation of the respiratory component 12 from the belt 20 even if caught on machinery or other apparatus. The mounting assembly 18 provides easy attachment and detachment of the respiratory component 12 to and from the belt 20 and facilitates efficient interchange between respiratory components carried by the belt. To attach or remove the respiratory component 12 from the belt 20, the free ends 28, 30 of the clip 18 are inserted into or removed from the clip openings 34, 36 in the respiratory component 12. Detent tabs 100 and 102 are pressed towards the second surface 88 of the clip 18 to facilitate insertion and removal of the clip from the respiratory component. At least the free ends 28, 30 of the clip 18 are flexibly resilient to accommodate insertion and removal to and from the clip openings 34, 36 of the respiratory component 12. The intermediate portion 26 of the clip 18 is sufficiently flexible to weave through the mounting slots 32 of the belt 20. FIGS. 10-13 illustrate a further embodiment of the inventive mounting assembly, a mounting clip 110, for attaching a respiratory component 12 to the belt 20. The mounting clip 110 includes an intermediate portion 112 and two spaced apart first and second free ends 114, 116 connected to the intermediate portion 112. The mounting clip has a first surface 118 and a second surface 120. The intermediate portion 112 extends between a first pair of living hinges 122 and a second pair of living hinges 124, which connect the intermediate portion 112 to the first and second free ends 114, 116, respectively. The free ends 114, 116 of the mounting clip 110 fold and extend, at the living hinges 122, 124, between a folded, use position (shown in solid lines in FIG. 10) and an extended position (shown in broken lines in FIG. 10). In the use position, the free ends 114, 116 are aligned to extend toward each other and the second surface 120 of the intermediate portion 112 and the free ends 114, 116 are aligned generally horizontally relative to the intermediate portion 112. Each pair of living hinges 122, 124 includes an upper hinge 122a, 124a and a lower hinge 122b, 124b spaced apart and separated by a connector wall 126a, 126b. The first surface 118 of the intermediate portion 112 defines a channel 128 extending between a first channel wall 130 and a second channel wall 132. The intermediate portion 112 also includes first and second intermediate ledges 134, 136. The first intermediate ledge 134 extends from a first shoulder 138 adjacent the first channel wall 130 to the first, upper living hinge 122a. The second intermediate ledge 136 extends from a second shoulder 140 adjacent the second channel wall 132 to the second, upper living hinge 124a. Each free end 114, 116 is stepped, as at stepped walls 114a and 116a, and includes an end ledge 142, 144 generally parallel and horizontally aligned with its respective intermediate ledge 134, 136, when the free ends 114, 166 are in the extended position. Each free end 114 and 116 also includes an outermost free ledge 142a and 144a, respectively, extending beyond stepped walls 114a and 116a. FIG. 13 is a cross-sectional view of the waist-mounted respiratory component system 24 talcen along line A-A of FIG.4, showing the respiratory component mounting clip 110 and another respiratory component 12A mounted to the belt 20. An example of a suitable respiratory component for use with the mounting clip 110 is JUPITER brand respirator from 3M Company of St. Paul, MN. First and second clip openings 34, 36 of the respiratory component 12 receive the intermediate portion 112 of the clip 110. The openings 34, 36 of the respiratory component 12A receive the intermediate portion 112 of the clip 110 whereby the intermediate portion 112 is woven through the openings 34, 36 and passes along an outer wall 146 ofthe respiratory component 12A. The free ends 114, 116 ofthe clip HO arewoven through the mounting slots 32 ofthe belt 20, whereby the end ledges 142 and 144 ofthe free ends 114, 116 project along the outer face 52 ofthe belt 20, while the outermost free ledges 142a, 144a project along the inner face 54 ofthe belt 20. In the embodiment shown in FIG. 13, four ofthe mounting slots 32a, 32c, 32d and 32f receive the walls 126a, 114a, 116a and 126b, respectively, of free ends 114, 116 ofthe clip 110. Between each mounting slot 32, one of the two surfaces (118, 120) ofthe clip 110 aligns against either the outer face 52 or the inner face 54 ofthe belt 20. To attach or remove the respiratory component 12 from the belt 20, the free ends 114, 116 of the clip 110 are inserted into or removed from the mounting slots 32 in the belt 20. At least the free ends 114, 116 of the clip 18 are flexibly resilient to accommodate insertion and removal to and from the mounting slots 32 ofthe belt 20. The intermediate portion 112 of the clip 110 is sufficiently flexible to weave through the clip openings 34, 36 ofthe respiratory component 12A. The mounting assembly 110 shown in FIGS. 10-13 is particularly useful in explosive or dusty environments. As seen in FIG. 14, a protective pouch 148 can be used to encase the respiratory component 12 to keep dust out of the component and/or prevent explosive materials from coming into contact with the component. FIG. 14 is a side view of the respiratory component 12A encased in the protective pouch 148. In FIG. 13, the protective pouch 148 is shown in phantom. An example of a suitable protective pouch for use with the mounting clip is JUPITER IS brand protective pouch from 3M Company of St. Paul, MN. The respiratory component 12A is placed in the protective pouch 148 and the intermediate portion 112 ofthe mounting clip 110 is inserted through the openings 34, 36 on the respiratory component 12. The pouch 148 includes sleeves 150, 152 for free ends 114 and 116 ofthe mounting clip 110 to pass through. The free ends 114, 116 of the mountmg clip 110 proj ect through the pouch 148 while the intermediate portion 110 is enclosed within the pouch 148. Because the free ends 114, 116 are received by the belt 20 (rather than the respiratory component 12), the respiratory component 12A is enclosed in the pouch 148, yet still detachable from the belt 20 without exposing the respiratory component 12A to a harmful environment. In further applications of the mounting assembly 110, the respiratory component 12A is not encased in the protective pouch 148. FIGS. 15-18 illustrate a further embodiment of the inventive mounting assembly, a mounting clip 160, for attaching a respiratory component 12 to the belt 20. The mounting clip 160 includes an intermediate portion 162 and two spaced apart free ends 164, 166 connected to the intermediate portion 162. The intermediate portion 162 extends between a first shoulder 168 and a second shoulder 170, while the first and second free ends 164, 166 extend from the first and second shoulders 168, 170, respectively. The free ends 164, 166 are aligned to extend in generally opposite directions. The mounting clip 160 has a first surface 172 and a second surface 174. The first and second free ends 164, 166 ofthe mounting clip 160 include first and second biased detent tabs 176, 178 extending generally downwardly and inwardly from the second surface 174 ofthe mounting clip 160. The first surface 172 of the intermediate portion 162 defines a channel 180 extending between a first outer wall 182 and a second outer wall 184. The channel 180 includes a stepped portion 186 extending towards the first surface 172 and defining a second channel 188 on the second surface 174 ofthe mounting clip 160. A depth ofthe first channel 180 (defined by walls 182 and 184) is greater than a depth ofthe second channel 188 (defined by walls 188a and 188b). Formed in the channel 180 are first and second subchannels 190, 192, which extend towards the second surface 174 and are defined on the first surface 172 of the mounting clip 160. A depth of each subchannel 190 (defined by walls 190a and 188a) and 192 (defined by walls 192a and 188b) is substantially equal to the depth ofthe second channel 188. First and second ledges 194, 196 extend between the first and second subchannels 190, 192 and the first and second outer walls 182, 184, respectively. Ledge 190b is in the subchannel 190, ledge 192b is in the subchannel 192, and the stepped portion 186 is in the channel 188 and separates subchannels 190 and 192. FIG. 18 is a cross-sectional view ofthe waist-mounted respiratory component system 24, taken along line A--A of FIG.4, showing the respiratory component mounting clip 160 and an alternative respiratory component 161 mounted to the belt 20. An example of a suitable respiratory component for use with the mounting clip 160 is DUSTMASTER brand respirator from 3M Company of St. Paul, MN. The intermediate portion 162 ofthe clip 160 is woven through the mounting slots 32 ofthe belt 20, whereby the free ends 164, 166 project from the inner surface 54 of the belt 20. h the embodiment shown in FIG. 18, four ofthe mounting slots 32b, 32c, 32d and 32e receive walls 190a, 188a, 192a and 188b, respectively, of the intermediate portion 162 ofthe clip 160. Between each adjacent mounting slot 32a-32f, one ofthe ledges 194, 190b, 186, 192b and 196 ofthe two faces (172, 174) ofthe clip 160 aligns against either the outer face 52 or the inner face 54 ofthe belt 20. The respiratory component 161 includes first and second openings 34a and 36a for removably receiving the free ends 164, 166 ofthe clip 160. The respiratory component 161 also includes first and second opposed detent surfaces 198, 200 adjacent the first and second clip openings 34, 36, respectively. The openings 34a and 36a of the respiratory component 161 receive the free ends 164, 166 ofthe clip 160 whereby the detent tabs 176, 178 of the clip 160 form a locking engagement with the detent surfaces 198, 200 of the respiratory component 161. To attach or remove the respiratory component 12 from the belt 20, the free ends 164, 166 ofthe clip 160 are inserted into or removed from the clip openings 34, 36 in the respiratory component 161. Detent tabs 176, 178 are pressed towards the second surface 172 ofthe clip 160 to facilitate insertion and removal ofthe clip from the respiratory component. At least the free ends 164, 166 of the clip 160 are flexibly resilient to accommodate insertion and removal to and from the clip openings 34, 36 ofthe respiratory component 161. The intermediate portion 162 ofthe clip 160 is sufficiently flexible to weave through the mountmg slots 32 ofthe belt 20. FIGS . 19-32 present alternative mounting clip designs for use with the belt 20, which are formed for use with different respiratory components or to allow different modes of assembly ofthe relative components. FIGS . 19 and 20 are top and side views, respectively, of a further embodiment of a respiratory component mounting clip 210. The mounting clip 210 shown in FIGS . 19 and 20 is similar to the mounting clip 160 shown in FIGS. 15-18, but does not include biased detent tabs. The mounting clip 210 includes an intermediate portion 212 and two spaced apart free ends 214, 216 connected to the intermediate portion 212. The intermediate portion 212 extends between a first shoulder 218 and a second shoulder 220, while the first and second free ends 214, 216 extend from the first and second shoulders 218, 220, respectively. The free ends 214, 216 are aligned to extend in generally opposite directions. The mounting clip 210 has a first surface 22 and a second surface 224. The first surface 22 of the intermediate portion 212 defines a channel 226 extending between a first outer wall 228 and a second outer wall 230. The channel 226 includes a stepped portion 232 extending towards the first surface 222 and defining a second channel 234 on the second surface 224 ofthe mounting clip 210. A depth ofthe first channel 226 (defined by walls 228 and 230) is greater than a depth ofthe second channel 234 (defined by walls 234a and 234b). First and second subchannels 236, 238 formed in the channel 226 extend towards the second surface 224 and are defined on the first surface 222 of the mounting clip 210. A depth of each subchannel 236 (defined by walls 236a and 234a) and 238 (defined by walls 238a and 234b) is substantially equal to the depth ofthe second channel 234. First and second ledges 240, 242 extend between the first and second subchannels 236, 238 and the first and second outer walls 228, 230, respectively. To attach the respiratory component 12 to the belt 20, this embodiment ofthe mounting clip 210 is used in the same fashion as those discussed above with respect to FIGS . 6-9 and 15-18. The intermediate portion 210 of the clip 212 is woven through suitable mounting slots 32 of the belt 20, whereby the free ends 214, 216 project from the inner surface 54 ofthe belt 20. Between mounting slots 32, one ofthe two faces (222, 224) ofthe clip 210 aligns against either the outer face 52 or the inner face 54 ofthe belt 20. To attach or remove the respiratory component 12 from the belt 20, the free ends 241, 216 ofthe clip 210 are inserted into or removed from the clip openings 34, 36 in the respiratory component 12. FIGS .21 and 22 are top and side views, respectively, of a further embodiment of a respiratory component mounting clip 250.

The first surface 378 of the intermediate portion 372 defines a channel 386 extending between a first outer wall 388 and a second outer wall 390. A subchannel 392 is defined in the channel 386 and first and second ledges 394, 396 connect the subchannel 392 to the first and second outer walls 388, 390, respectively. To attach the respiratory component 12 to the belt 20, this embodiment ofthe mounting clip 370 is used in the same fashion as those discussed above with respect to FIGS. 6-9 and 15-18. The intermediate portion 372 of the clip 370 is woven through suitable mounting slots 32 of the belt 20, whereby the free ends 374, 376 project from the inner surface 54 ofthe belt 20. Between mounting slots 32, one ofthe two faces (378, 380) ofthe clip 370 aligns against either the outer face 52 or the inner face 54 ofthe belt 20. To attach or remove the respiratory component 12 from the belt 20, the free ends 274, 276 ofthe clip 270 are inserted into or removed from the clip openings 34, 36 in the respiratory component 12. FIGS . 31 and 32 are top and side views, respectively, of a further embodiment of a respiratory component mounting clip 400. The mounting clip 400 includes an intermediate portion 402, two spaced apart free ends 404, 406 connected to the intermediate portion 402, a first surface 408 and a second surface 410. The intermediate portion 402 extends between a first shoulder 412 and a second shoulder 414, while the first and second free ends 404, 406 extend from the first and second shoulders 412, 414, respectively. The free ends 404, 406 are aligned to extend in generally opposite directions. The first and second free ends 404, 406 ofthe mounting clip 400 include first and second biased detent tabs 416, 418 extending generally downwardly and inwardly from the second surface 408 ofthe mounting clip 400. The first surface 408 of the intermediate portion 402 defines a channel 420 extending between a first outer wall 422 and a second outer wall 424. A subchannel 426 is defined in the channel 420 and first and second ledges 428, 430 connect the subchannel 426 to the first and second outer walls 422, 424, respectively. To attach the respiratory component 12 to the belt 20, this embodiment ofthe mounting clip 400 is used in the same fashion as those discussed above with respect to FIGS. 6-9 and 15-18. The intermediate portion 402 of the clip 400 is woven through suitable mounting slots 32 of the belt 20, whereby the free ends 404, 406 project from the inner surface 54 ofthe belt 20. Between mounting slots 32, one ofthe two faces (408, 410) ofthe clip 400 aligns against either the outer face 52 or inner face 54 ofthe belt 20. To attach or remove the respiratory component 12 from the belt 20, the free ends 404, 406 ofthe clip 400 are inserted into or removed from the clip openings 34, 36 in the respiratory component 12. The respiratory protection system is generally used in hazardous and contaminated environments, thereby requiring that the mounting assemblies, and other components, be readily decontaminatible such that they may be reused in further applications. In addition, at least the free ends 28, 30 of the mounting clip 18 are flexibly resilient to accommodate insertion and removal to and from respiratory component clip openings 34, 36. The intermediate portion 26 of the clip 18 is sufficiently flexible to weave through the mounting slots 32 ofthe belt 20. The mounting clips are formed from a polypropylene, nylon or polyethylene, for example, by injection molding or vacuum forming. An example of a suitable polypropylene is FINA 4460 from Atofina (Houston, TX). Each mounting clip has a thickness of approximately 2.2 mm. In further embodiments of the respiratory component system, the belt 20 includes sufficient mounting slots 32 for accommodating more than one mounting clip 18, and thereby facilitating the attachment of more than one respiratory component 12. Rather than just attaching a respiratory component at the back section 42 of the belt 20, additional components may attached along the entire outer perimeter of the belt 20. In addition, the alignment of the free ends 28, 30 of a mounting clip 18 may be different from one clip to another to accommodate differing orientations of connector receptacles 34, 36 on the respiratory components. Although the present invention has been described with reference to several embodiments, workers skilled in the art will recognize that changes may be made in form and detail without departing from the spirit and scope ofthe invention. For example, a multitude of mounting assemblies including an intermediate portion and two spaced apart free ends are possible for attaching a respiratory component to a user-wearable support member. Thus, the invention is not limited to the embodiments disclosed and described above, and additional embodiments may include fewer or more channels, stepped portions, ledges, detent tabs and/or hinges.
