  • the pressurized gas filled in the gas cylinder 45 is discharged, enters the three-way pipe 40, and flows into the airbag 32 in the protective layer 20 from the branch pipe 42. At this time, the airbags 32 of all the protective layers 20 are inflated as shown in FIGS. 4A to 4C, and change from FIG. 2A to FIG. 2B.

  • the time from when the sensor detects an abnormality and the electric igniter 50 is activated until the airbag 32 is inflated is the same as the time until the airbag device of the automobile is activated and the airbag is inflated. It is about several tens of milliseconds (for example, 40 to 60 milliseconds). Therefore, since the airbags 32 of all the protective layers 20 are inflated in a very short time until the worker falls or falls and comes into contact with the ground or floor surface, the impact when the worker collides with the ground or floor surface. Is alleviated.
  • the airbag 32 is inflated between the front surface side protective plate 31 and the back surface side protective plate 33, the protective layer 20 of the protective clothing 10 is formed by A three-layer structure will be formed, and this three-layer structure acts to greatly reduce the impact.
  • the front surface side protection plate 31 is harder than the back surface side protection plate 33, thereby making it difficult to transmit the impact to the human body, and the impact transmitted to the human body is also attenuated by the soft back surface side protection plate 33.
  • the airbag 32 is disposed between the front surface side protection plate 31 and the back surface side protection plate 33, the impact is greatly attenuated.
  • the impact is also caused by having the protective layer 20 in a state where the airbag 32 is not inflated.
  • the protective layer 20 is disposed in a state where the airbag is folded into a plurality of layers and has a thickness, the cushioning property of the protective layer 20 is increased, so that the impact mitigating function is enhanced.

It is determined that there is a characteristic, and an operation signal is transmitted from the transmitting device 103 to the receiving device 105 attached to the protective clothing 10 by wireless communication.
  • the receiving device 105 sends the received signal to the control device of the protective clothing 10, and the control device operates the electric igniter 50 to inflate the airbag of the protective clothing 10. Since the air bag of the protective clothing 10 is inflated, the worker can be aware of the presence of the intruding vehicle in advance, so that it may be possible to avoid the intruding vehicle in advance, and the intruding vehicle cannot be avoided. Even in such a case, the worker is protected by the protective clothing 10 with the airbag inflated.

Abstract

La présente invention vise à accroître la sécurité de travail d'ouvriers. Le vêtement de protection (10) comprend de multiples couches de protection (21-24) formées entre une surface avant (11) et une surface arrière (12) du vêtement de protection (10), un moyen d'alimentation en gaz (35), un capteur, une unité de commande et une source d'énergie. Dans l'ordre de la surface avant à la surface arrière, les couches de protection (21-24) comprennent une plaque de protection côté surface avant (31), un coussin gonflable (32) relié au moyen d'alimentation en gaz (35), et une plaque de protection côté surface arrière (33). Le moyen d'alimentation en gaz (35) utilise un gaz mis sous pression rempli à l'intérieur d'un cylindre à gaz comme source de gaz, et introduit le gaz mis sous pression dans le cylindre à gaz à l'intérieur du coussin gonflable (32) pour le gonfler.
