Embodiment Construction

[0033] refer to figure 1 , this figure shows a harness 100 for a respirator comprising a structural support member in the form of a back frame 10 . Harness 100 includes left and right shoulder straps 110 , 120 , a waist belt 130 and a cylinder retention strap 136 . The gas cylinder decompression valve 140 is installed in the lower part 11 of the back frame 10 . A high pressure tube 150 and a medium pressure tube 152 extend from the pressure relief valve 140 along the back frame 10 to a position on the left shoulder strap 110 and the right shoulder strap 120 .

[0034] Such as figure 2 In use, the cylinder 1 is mounted to the back frame 10 of the harness 100 as shown in . The first end 2 of the gas bottle is supported by the lower part 11 of the back frame 10 and the second end 3 of the gas bottle is supported by the upper part of the back frame 10 . The first end 2 of the cylinder is connected to a pressure relief valve 140 installed in the lower part of the back frame 10...

Abstract

The present invention relates to a two-part structural support member for a harness for a breathing apparatus is generally elongate and arranged in use to support a cylinder of breathable gas and one or more components operatively associated with the breathing apparatus, wherein the structural support member comprises first and second parts (20, 30) defining therebetween a housing for retaining one or more of the components.

Description

technical field [0001] The present invention relates to a structural support member for use with a harness for a respirator, and more particularly to a structural support member comprising a first connecting member and a second connecting member, the first connecting member and A shroud for retaining the assembly is defined between the second connectors. Background technique [0002] A self-contained breathing apparatus (SCBA) harness includes a structural support member for supporting a cylinder of breathable gas, and a pair of shoulder straps and a belt for easily carrying the structural support member on a user's back. The structural support member is provided with a valve near its lower end and a retaining strap at its upper end. In use, the cylinder of breathable gas is connected to the valve and is further secured to the structural support member using a retaining strap made to pass around the upper portion of the cylinder. A plurality of flexible tubes extend from t...
