Abstract

There is disclosed a harness for breathing apparatus, the harness arranged to support a plurality of cylinders of breathable gas side-by-side. The harness comprises a plurality of longitudinally extending cylinder channels arranged side-by-side, each cylinder channel having a rear wall and open at least partially along its length and arranged to accommodate a cylinder. Adjacent cylinder channels are laterally separated by a longitudinally extending channel side wall that in use is disposed between adjacent cylinders.

Claims

1-22. -22. (canceled)

23. A breathing apparatus set comprising:

a harness comprising;

upper and lower longitudinally spaced housings coupled together by a longitudinally extending back member;

left and right shoulder straps;

a waist belt;

at least three longitudinally extending cylinder channels arranged side-by-side;

at least two channel side walls, each channel side wall laterally separating a pair of adjacent cylinder channels; and

at least two conduit retainers, each conduit retainer coupled to a channel side wall;

at least three cylinders of breathable gas supported by the harness and located side-by-side, the cylinders having their upper portions retained by the upper housing and their lower portions retained by the lower housing, wherein each cylinder is disposed in a respective cylinder channel with a channel side wall disposed between adjacent cylinders;

at least two conduits, each conduit fluidically coupled to a cylinder and attached to a conduit retainer at a position in front of the cylinders so as to inhibit the withdrawal of the respective channel side wall from between adjacent cylinders.

42. A breathing apparatus set comprising:

a harness in accordance with claim 23; and

a plurality of cylinders of breathable gas supported by the harness, wherein each cylinder is disposed in a cylinder channel.

24. A harness for breathing apparatus, the harness arranged to support a plurality of cylinders of breathable gas side-by-side, the harness comprising a plurality of longitudinally extending cylinder channels arranged side-by-side, each cylinder channel having a rear wall and open at least partially along its length and arranged to accommodate a cylinder, wherein adjacent cylinder channels are laterally separated by a longitudinally extending channel side wall that in use is disposed between adjacent cylinders.

25. A harness according to claim 24, wherein the or each channel side wall is provided with a retaining means which in use is arranged to inhibit the withdrawal of the or each channel side wall from between adjacent cylinders.

26. A harness according to claim 24, wherein the or each channel side wall is provided with a conduit retainer such that in use a conduit can be attached to the channel side wall so as to inhibit the withdrawal of the channel side wall from between adjacent cylinders.

27. A harness according to claim 26, wherein the or each conduit retainer comprises a conduit retainer channel that longitudinally extends with the channel side wall and within which a conduit can be retained.

28. A harness according to claim 27, wherein the or each conduit retainer channel is coextensive with the respective channel side wall.

29. A harness according to claim 27, wherein the or each conduit retainer channel can be opened along its length so that a conduit can be inserted into and removed from the conduit retainer channel.

30. A harness according to claim 24, wherein the rear walls and/or the or each channel side wall comprises a layer of fabric.

31. A harness according to claim 30, wherein the rear walls and the or each channel side wall is formed from a continuous layer of fabric.

32. A harness according to claim 24, wherein the or each channel side wall comprises a double layer of fabric.

33. A harness according to claim 32, wherein the or each double layer of fabric is stitched together along a first longitudinally extending line between the channel side wall and an adjacent pair of rear walls.

34. A harness according to claim 32, wherein the or each double layer of fabric is stitched together along a second longitudinally extending line which is rearward of a forward-facing edge of the channel side wall.

35. A harness according to claim 24, wherein the or each channel side wall is provided with a conduit retainer such that in use a conduit can be attached to the channel side wall so as to inhibit the withdrawal of the channel side wall from between adjacent cylinders;

wherein the or each conduit retainer comprises a conduit retainer channel that longitudinally extends with the channel side wall and within which a conduit can be retained;

wherein the or each channel side wall comprises a double layer of fabric which is stitched together along a second longitudinally extending line which is rearward of a forward-facing edge of the channel side wall;

wherein the stitching along the second longitudinally extending line forms at least part of the conduit retainer channel.

36. A harness according to claim 24, further comprising a cover that can be moved between at least a closed configuration in which in use the cylinders are covered and an open configuration in which in use the cylinders are at least partially exposed.

37. A harness according to claim 24, further comprising upper and lower longitudinally spaced housings arranged to retain upper and lower portions of each cylinder respectively, wherein the plurality of cylinder channels extend between the upper and lower housings.

38. A harness according to claim 37, wherein the upper and lower longitudinally spaced housings are coupled together by a longitudinally extending back member.

39. A harness according to claim 38, wherein the longitudinally extending back member comprises the plurality of cylinder channels.

40. A harness according to claim 39, wherein the back member comprises a layer of fabric.

41. A harness according to claim 24, wherein there are at least two, at least three or at least four cylinder channels.
