Is a compressed gas supply device (compressed air cylinder), 22 is a drop detection sensor, 23 is a near-miss sensor, and 31 is an inflated protective suit (vest).

That is, in this embodiment, as shown in FIGS. 1 and 2, the protective clothing to which the present invention is applied is a vest 1, and the vest 1 is constituted by an airbag 2 which also serves as a clothing main body. Have been. The airbag 2, which is a garment body of the vest 1, is made of rubber or synthetic fiber, and has a back body 3, left and right front bodies 4,5 and a collar 6, and has left and right front bodies 4,5. Can be combined by the fastener 7. In addition, two pockets 8, 8 arranged side by side at the lower part on the front side of the right front body 4, and two pockets 9, 9 arranged side by side at the lower part on the front side of the left front body 5,
Furthermore, on the front side of the right front lookout 4 are lower pockets 8,8.

As shown in FIG. 2, a compressed air cylinder 21 serving as a compressed gas supply device to the airbag 2 which is the garment main body of the vest 1 is built in the lower pocket 17 inside the front left best view 5. Have been. Further, as shown in FIG.
Has a built-in drop detection sensor 22 for detecting a free fall motion, for example, an acceleration sensor or the like. Also,
Two pockets 1 side by side in the middle part on the front side at the right front view 4
One of the sensors 1 and 11 has a built-in near-miss sensor 23 for detecting a near-miss or a dangerous state based on the measurement of the human heart rate, blood pressure and brain waves.

The vest 1 having the above-described configuration is configured such that when a worker wearing the vest 1 falls from, for example, a building skeleton during construction work, the free fall movement of the vest 1 is incorporated in a fall detection sensor built in the vest 1. When the air bag 2 detects, the compressed air cylinder 21 is operated, and the compressed air is supplied at a stretch to instantly inflate the air bag 2 which is the garment main body of the vest 1 into a tubular shape. As a result, as shown in FIG. 3 and FIG.
Thus, the upper body of the worker can be protected from the impact. Moreover, the airbag 2 which is the garment body of the vest 1
Is instantaneously inflated into a tubular shape, and at the same time, the collar 6 is also inflated so as to wrap around the head of the human body. The impact on the upper body including the head of the human body can be reduced.

It is preferable that the airbag 2, which is the garment main body of the vest 1, has a speed of inflating when dropped from a height of about 2 to 10 m and a shock absorbing function. By giving such a function to the vest 1, it is possible not only to cope with a fall accident from the building frame, but also to cope with a fall accident when working on a stepladder where a lifeline cannot be used, for example.
As described above, the vest 1 that detects the fall of the worker and inflates the airbag 2 instantaneously may be used. However, in addition to the detection of such a fall, the near-miss sensor 23 may be used in a dangerous state. The vest 1 may be configured to instantly inflate the airbag 2 when it is detected.

That is, in addition to detecting that the worker has fallen by the fall detection sensor 22, the worker uses the near miss sensor 23 incorporated in the vest 1 based on the measurement of the heart rate, blood pressure and brain wave of the human body. When it is detected that the airbag 2 is in a dangerous or dangerous state, the compressed air cylinder 21 is operated, and the airbag 2 is instantaneously inflated into a tubular shape by the supply of the compressed air. .
In this way, for example, as in the case of intentionally jumping down from a low scaffold, the inflating operation of the airbag 2 which is not necessarily required is avoided, and the airbag 2 is only required in a dangerous case which is originally required.
Can be reliably inflated and actuated.

FIG. 5 is a perspective view showing an example of a helmet worn by a worker, and FIG. 6 is a schematic perspective view exemplifying a case in which the worker loses his / her feet by dropping from a scaffold. In this embodiment, the near-miss sensor 23 incorporated in the vest 1 described above is used as a sensor for detecting that the worker is in a near-miss or unsafe state, as shown in FIG. On the helmet,
In addition to the function of measuring the heart rate, blood pressure, and brain waves of the human body, a function of transmitting the measurement signals is also provided, and the measurement signals of the heart rate, blood pressure, and brain waves are wirelessly transmitted to the near-miss sensor 23. Thus, for example, as shown in FIG.
When a worker falls from the moving scaffold 61, the fall detection sensor 22 detects that the worker has fallen, and the heart rate, blood pressure, and brain wave measurement signals from the helmet 51 worn by the worker are best wirelessly. The compressed air cylinder 21 is sent to the near-miss sensor 23 built in 1 and detects that the worker is in a near-risk or dangerous state based on the measurement of the heart rate, blood pressure and brain waves. When activated, the airbag 2 is instantaneously inflated into a tubular shape by the supply of the compressed air.

The heart rate and blood pressure are measured by the near-miss sensor 23 and the helmet 51 is provided with an electroencephalogram measurement function and a transmission function of the measurement signal, and the measurement signal of the electroencephalogram is wirelessly transmitted to the near-hear sensor. 23.
By measuring the heart rate, blood pressure, and brain waves as described above and sending them to the management system at the entrance to the site, the daily health status of the workers can be grasped and managed. become able to. Further, it is possible to grasp and manage the current position of the worker.

In the above-described embodiment, the vest is used for construction work. However, the present invention is not limited to this. And upper and lower clothes covering the lower body and legs, such as winter clothes, and may be protective clothes for civil engineering work or other fishing. Further, in the embodiment, the compressed gas supply device is a compressed air cylinder. However, the compressed gas supply device is not limited thereto, and may be a gas generation device as in the case of a vehicle airbag. Further, the specific configuration of the drop detection sensor is also arbitrary, and it goes without saying that the specific detailed structure and the like can be appropriately changed.
