Description

  The present invention relates to a safety band used during work at a high place, and is particularly worn during work involving the use of a respiratory organ.

  When carrying out fire fighting and rescue activities at a fire site, firefighters or rescue crews wear fireproof clothing on the crew's clothing, and also carry a respirator with an air cylinder set to ensure air breathing. I am doing work.

  For example, as shown in Patent Document 1, this respirator is provided with a fixing waist belt, a shoulder belt or the like attached to a backpack (hanger) along the back of the worker, and an air cylinder on the back of the backpack. To fix. An operator wears the respiratory apparatus on his / her back through the waist belt and shoulder belt (see, for example, Patent Document 1).

Furthermore, in situations where activities at high altitudes are required, wearing safety belts is also required to prevent a crash. For this reason, as a result, the worker has to wear the belts for two purposes of the belts for fixing the respirator and the waist belt of the safety belt separately.
JP-A-9-285558

  The waist belt for fixing the respiratory organ is preferably attached around the hip bone so as to support a large weight such as an air cylinder. In general, in addition to carrying a heavy object on the shoulder, it is possible to minimize the burden on the body by supporting the lower part in close contact with the vicinity of the hip bone. This is because if it is in close contact with the vicinity of the hip bone, the heavy object is less likely to shake and stabilizes at the waist, so that the burden on the shoulder via the shoulder belt can be reduced. However, since it is desirable to wear the waist belt of the safety belt around the hip bone in order to reduce the burden on the body when preventing the fall, both of them cannot be worn at the optimum position at the same time. For this reason, if the waist belt for fixing the respiratory apparatus is mounted in the vicinity of the hip bone, the waist belt of the safety belt has to be mounted shifted from the position. Since the shifted mounting position is not the optimal mounting position inherent in the safety belt, it is not preferable for minimizing the burden on the body when the fall is prevented.

  Accordingly, an object of the present invention is to make it possible to attach the waist belt of the safety belt to a predetermined position around the hipbone even when the respiratory organ is carried on the back.

  In order to solve the above-described problems, the present invention is configured such that a backpack (hanger) for fixing an air cylinder of a respirator can be detachably attached to a torso belt of a safety belt. In this way, the respirator carried by the operator can be fixed to the waist belt of the safety belt so that it does not move around its waist, so that the respirator is prevented from shaking and stabilized at the waist. The burden on the body due to weight can be reduced. In addition, the waist belt functioning as a safety belt also functions as a waist belt for fixing the respiratory organ at the same time, so that both the safety belt and the respiratory belt can be mounted at the optimum positions around the waist.

  Since the present invention is configured as described above, the torso belt of the safety belt can be mounted at the optimum position around the hipbone even when the respiratory organ needs to be carried on the back.
