BEST MODE FOR CARRYING OUT THE INVENTION

(First Embodiment) FIG.
As shown in the developed plan view of FIG. 1, a non-breathable fabric is sewn and tailored, and a head protection airbag 2 for protecting the head of the human body and a torso protection for protecting the torso of the human body Protect the airbag 3 and the neck of the human body,
3 and a neck protection airbag 1 connecting the
An initiating device 4 is provided for sending gas to the three airbags 1 to 3 which are communicated with each other to rapidly inflate the airbags 1 to 3. Both ends of the head protection airbag 2 are connected by at least one connecting belt 21, and the body protection airbag 3 is provided with a mounting belt 31 and a buckle 32.

As shown in FIG. 2, of the three airbags, the head protection airbag 2 and the trunk protection airbag 3
Is folded into a jacket when not in use so that it is not hindered when worn on the human body. In FIG. 1, this folding method is bent inward along the dotted line, bent outward along the alternate long and short dash line, and temporarily fixed by the pile-shaped raised locking piece 34 so as not to open.

The squib 4 is operated by electric or mechanical means to rapidly inflate the airbag as shown in FIG. 3, and uses the same device as that for inflating the airbag of a car. You just have to do it. In order to protect the human body by mitigating the impact on the human body when the detonator 4 is operated, a protection plate 41 is interposed on the side in contact with the human body, as shown in the sectional view of FIG.

Means for activating the detonating device 4 include a zero-gravity detecting device 5 for detecting a zero-gravity state and generating an electrical output.
Use

[0011] As shown in FIG.
Is operated by a battery, a spherical weight 56 is placed in a tetrahedron container 51, and micro switches 52 to 55 that are operated by the weight 56 are provided at the center of each regular triangular surface of the tetrahedron. Things. As shown in the circuit diagram of FIG. 6, each of the micro switches 52 to 55 is connected to each of four inputs of an AND circuit 57 together with a pull-up resistor 59.
The output of 57 is connected to a timer circuit 58 that generates an output when the input has continued for a certain period of time or more. Then, the explosion device 4 is operated by the output of the timer circuit 58.

When the thus constructed human body protection device is worn on the human body and working, the weight 56 of the weightlessness detection device 5
However, since at least one of the micro switches 52 to 55 is operated, no output is generated from the AND circuit 57, and thus no output is generated from the timer circuit 58. If the person wearing the personal protective equipment jumps or jumps down from a low place, it will be in a zero gravity state for a short time, and the weight 56 of the zero gravity detection device 5 will operate any of the micro switches 52 to 55. Even if an output is generated from the AND circuit 57 without being performed, if the time during which the output of the AND circuit 57 is generated is short, the detonator 4 is not operated without generating an output from the timer circuit 58.

However, when a person wearing the human body protection device falls from a high place, the weight 56
However, the time during which none of the micro switches 52 to 55 is operated becomes longer, and the time during which an output is generated from the AND circuit 57 becomes longer. Before the airbag is hit against the ground, the airbag is rapidly inflated to protect the human body as shown in FIG.

As a weightlessness detecting device 5, even if a regular hexahedron container is used instead of a regular tetrahedron container, a spherical weight is placed in the container, and a micro switch is provided at the center of each square surface, The same operation can be performed.

(Second Embodiment) The first embodiment described above
In the embodiment, the weight 56 and the micro switches 52 to 52
Although a device combining 55 is used, the same operation can be performed using an accelerometer.

As this accelerometer, FIG.
As shown in FIG. 9D, the upper electrode 66, the lower divided movable electrodes 61 to 64 to which the weight 60 is attached, and the center electrode 65 are usually provided. As shown in FIG. The electrode 66 and each of the movable electrodes 61 to 65 are parallel and maintain a constant interval, but when acceleration is applied, the movable electrode 61 to 65 together with the weight 60
Moves, and the capacitance between the upper electrode 66 and each of the lower electrodes 61 to 65 changes.

As shown in FIG. 9C, when an acceleration in the X-axis direction is applied, the capacitance between the movable electrode 61 and the movable electrode 63 with respect to the upper electrode 66 changes. C1 to C3), and the acceleration in the Y-axis direction is obtained by detecting a difference (C2 to C4) in capacitance between the movable electrode 62 and the movable electrode 64 with respect to the upper electrode 66. As shown in FIG. 9D, the acceleration in the Z-axis direction changes the capacitance (C5) of the center electrode 65 with respect to the upper electrode 66. By detecting the change in the capacitance (C5), can get.

When the accelerometer constructed as described above is mounted on a human body protection device and working, normally, a synthetic acceleration of 1 G is detected. However, when the human body falls, the synthetic acceleration detected is 0 G. Approach. For example, when falling from a height of 1 m, as shown in the waveform diagram of FIG. 12, the combined acceleration detected during the fall approaches 0G.

The signals output from the accelerometer 6 corresponding to the respective accelerations in the X-, Y-, and Z-axis directions are shown in FIG.
The signal is input to a signal processing circuit using a microcomputer 70 shown in FIG. 1 and converted into digital signals by A / D converters 71 to 73, respectively, and then processed according to a flow chart shown in FIG.

That is, in Steps 1 to 3, the accelerations in the X-axis direction, the Y-axis direction, and the Z-axis direction are read. In Step 4, the resultant acceleration is calculated. In Step 5, the resultant acceleration approaches 0G. It is determined whether or not the falling state has continued for a certain period of time. If it is determined that the falling state has continued for a certain period of time, the initiator 4 is operated in step 6.

As described above, by using the accelerometer 6, when the detected synthetic acceleration approaches 0G and continues for a certain period of time, the detonator 4 is operated to rapidly inflate the airbag. It can also protect the human body.

(Third Embodiment) In the above-described embodiment, the detonating device 4 is automatically operated by the zero-gravity detecting device or the accelerometer. Alternatively, the string 4 may be pulled to mechanically activate the detonator 4. As described above, when the detonator 4 is manually operated to inflate the airbag, if a fire occurs in a high-rise building, the person left behind can wear the human body protection device of the present invention. If the airbag is inflated in advance to protect the human body and then jump down, the fear can be reduced.

When a zipper 33 is used as shown in FIG. 7 instead of the belt 31 and the buckle 32 for wearing the body protection airbag 3 on the body,
As shown in FIG. 8, the trunk can be surrounded without any gap.

[0024]

As is clear from the description based on the above embodiment, according to the human body protection device of the present invention, a region that is fatal when a human body falls from a high place can be surrounded by an airbag. Therefore, when jumping off in an extreme state with the airbag attached to the vehicle when jumping off in an extreme state, always in a high-rise building such as a hotel, the impact at the time of landing can be reduced and human life can be protected. Also, if the human body protection device of the present invention is previously mounted on a worker at a high place,
Even if the airbag accidentally falls, the airbag is automatically inflated and the impact at the time of landing can be reduced.
