However, according to the above technology, since the gas expansion impact mitigation device of [0010] uses a gas cartridge cylinder, the size of the air chamber is naturally limited to the capacity of the gas cartridge cylinder. The larger the size and weight of the object that is intended to mitigate the impact, the larger the capacity of the gas cartridge cylinder to ensure the necessary and sufficient air chamber size, which increases the weight of the device. There was a problem.
Therefore, an object of the present invention is to provide a degree of freedom of air chamber size without increasing the weight of the device.

In addition, according to the above technique, the atmospheric pressure expansion impact mitigation device of [0010] expands the air chamber having a complicated double structure and an inner valve, so that the air flow in the air chamber is naturally restricted. However, there is a problem that the expansion speed of the air chamber that expands by inhaling the atmosphere at the time of startup is slower than that of the gas expansion type impact mitigation device that fills the air chamber with compressed high-pressure gas from the gas cartridge cylinder.
Therefore, an object of the present invention is to provide an air chamber with an increased expansion speed.

Further, according to the above technique, the gas expansion type impact mitigation apparatus of [0010] expands by filling the gas chamber with a gas from a gas cartridge cylinder. It is mechanically impossible to re-expand from the chamber through the valve to the outside air, losing the ability to relieve shock at full expansion with time.
Generally, in the case of clothes-like impact mitigation devices worn by vehicle riders such as motorcycles and workers at high altitudes, in the case of bikes, bicycles, etc. In many cases, it is required to respond to a plurality of impacts in two steps and three steps after receiving the first impact.
Accordingly, an object of the present invention is to provide a mechanism that instantaneously re-expands each time in response to a plurality of impacts.

In addition, according to the technology of [0010], the gas expansion type impact relaxation device relieves the impact by the repulsive force of the air chamber pressure in a state where the expanded air chamber filled with the gas is distorted by expanding in the strain surface area. It is what.
However, a mechanism that absorbs an impact has a higher ability to mitigate the impact than an impact repelling, and as described in [0022], after receiving the first impact under the conditions of use. There is a possibility that the repulsion force of the impact mitigation device may generate a condition that more easily creates a two-stage, three-stage collision condition.
Accordingly, an object of the present invention is to provide a structure that absorbs impact.

Further, according to the above technology, the gas expansion impact mitigation device of [0010] cannot structurally detect damage / deterioration of the airbag or failure of the starter device or defective gas cartridge cylinders when not operating. There is a problem, and this is also the case with the airbags [0016] [0017] [0018].
Therefore, an object of the present invention is to provide a structure that facilitates the discovery of a failure or a defect.

Further, according to the above technique, since the gas expansion impact mitigation device of [0010] uses a gas cartridge cylinder, not only the rigidity of the structure of the starter unit is structurally required, but also the cylinder. In addition, heavy objects such as air springs such as opening springs are concentrated, and there is a problem in terms of weight balance when using a clothing-like main body worn by a vehicle passenger such as a motorcycle, an altitude worker, a walking trainer, etc. Yes.
Accordingly, an object of the present invention is to provide a structure and a shape that reduce the weight of the starting device portion.

Further, according to the technology of [0010], the gas expansion type impact mitigation device is a spherical shape that holds a needle pin for opening an automatic starting device for opening a sealing plug of a gas cartridge cylinder and suppresses a cylinder pushed by a spring. It takes about 3kg of force to start with the ball key coming out, and this is connected to the rider of a motorcycle, walking trainer, etc. with a ball key and a cable for automatic activation. When the object is a lightweight object such as a bicycle or a walking training device, there is a problem that it cannot be activated.
Therefore, in the case of automatic start-up, this device is used for motorcycles, trikes, snowmobiles, jet skis, etc. In the case of a garment-like body worn by a person, etc., a structure that automatically starts when the user's body is separated from the vehicle or device to be used by a certain distance or when the activation key is pulled out is provided. In addition, an object is to enable activation manually.
Also, emergency evacuation tents, emergency inflatable lifeboats, large-sized bumper airbags for vehicles and people, life jackets and emergency life-saving tools, avalanche airbags, with different main body sizes and shapes for different purposes and different startup times. It is an object of the present invention to enable activation with a similar structure for products that require a large air chamber, such as a safety cushion fence.

Further, according to the above technique, the atmospheric pressure expansion shock mitigation device of [0011] is not predictable in the event of an accident due to a hook-type wire guide fitted into a replaceable screw-on lid. The shape corresponding to the operation of the 180 degrees four-way key eliminates the blind spot of the operation and reduces the starting force by using a seal tape, but the vehicle rider such as a motorcycle, an altitude worker, etc. Or, as the actual situation of the accident caused by the object to be protected, there are many cases where the wire angle is at an angle of 180 degrees or more in front of the key body, and twisting phenomenon often occurs. There was a problem of obstructing.
Therefore, this device is worn by motorcycles, trikes, snowmobiles, jet skis and other vehicles and ship riders, altitude workers, anglers, parachute divers, skydivers, hang gliders, snowboarders, skateboarders, climbers, etc. In the case of a clothing-like body, when the user's body is away from the vehicle or device to be used, or the present invention having a body shape that matches the object to be protected and the purpose leaves the fixed distance from the wire fixing position It is an object of the present invention to provide a structure that can be automatically activated in a case, or can be easily activated when it is intentionally activated and does not prevent the air from flowing into the air chamber.

In addition, according to the techniques [0013] [0014] [0015] above, the air tent is a three-dimensional structure that is self-supporting by filling a plurality of air chambers with air, and has excellent water resistance and wind resistance in the event of a disaster or emergency. In addition, it has the ability to cope with falling objects, etc., and can be constructed regardless of the installation location, but all of them are equipped separately with a compressor, blower, pump, compressed air cylinder, etc. to fill the air chamber This requires an air filling device.
Therefore, an object of the present invention is to provide a structure for constructing a three-dimensional structure without using an air filling device.

  Further, according to the above technique, the atmospheric pressure expansion type impact mitigation device of [0012] has an air outlet / inlet opening and an exhaust valve that are opened by the activation key independently, and there are a plurality of valve devices. It is an object of the present invention to provide a structure in which the valve device is concentrated on the air inflow / outflow hole because the possibility of air leakage during compression is increased.

  [0012] According to the atmospheric pressure expansion shock mitigation device of [0012], the air chamber has a single-layer filler with an air passage inside, but the air chamber is filled when the air chamber is compressed. When exhausting the atmospheric air, the filler is compressed, and the airway near the exhaust hole provided in the filler is closed to reduce the exhaust efficiency. Therefore, this device compared with [0012] when the atmosphere flows into the air chamber, and when the air flows into the air chamber, the amount of air necessary for rebounding and restoring the filler to the original shape is shortened. The object is to provide a shape and structure of the airway that increases the flow velocity of the airflow that flows into the air chamber and expands the air chamber over time, and the packing material receives pressure from the air chamber due to the impact on the air chamber. It is an object of the present invention to provide an airway structure having an inner wall shape in which when the airflow flows out, the airflow is obstructed and the flow velocity is reduced, and a filler shape and structure that is efficient for compressive repulsion of the filler.

  [0012] According to the atmospheric pressure expansion shock mitigation device of [0012], a vehicle such as a motorcycle, a trike, a snowmobile, a jet ski, a ship occupant, an altitude worker, a fisherman, a parachute diver, a skydiver, a hang glider, In the case of a garment body worn by snowboarders, skateboarders, climbers, etc., since it has an air chamber inside the garment body, there was a problem with air permeability depending on the usage environment such as summer, It is an object of the present invention to provide a shape and a structure that gives a ventilation performance to an air chamber without deteriorating the impact relaxation performance.

  [0012] According to the atmospheric pressure expansion shock mitigation device of [0012], air chambers such as a tent, a large-scale emergency evacuation facility, a lifeboat for lifesaving, etc. are fixedly stored in the air chamber case, and the space between the outer skin, the inner skin, and the air chamber case is When fixedly connected, a three-dimensional structure can be constructed at the same time as starting, but even if it is an integral three-dimensional structure that matches the shape of the main body where the air chamber and the filler inside the air chamber are completed, In addition, even when the air chamber and the filler inside the air chamber are housed in a case that matches the shape of the main body as a unit, the separate structure is connected in the shape of the main body for expansion or connection. An object of the present invention is to provide a shape and a structure that can easily connect an air chamber and an air chamber, corresponding to the expansion according to the use situation and the use environment.

In order to solve the above problems, the first device is a case where the filler in the air chamber such as high resilience urethane which is compressible and has a resilience to the original shape is repelled and expanded to the original shape at the start of the present invention. Corresponding to an emergency start when the packing material receives pressure from the outside when the shock is received, when the shock goes away and rebounds and recovers again, or when the air chamber is compressed manually or by vacuuming for restarting When the standby state is maintained, the shape and function of the air chamber and the filling material in the air chamber change depending on the operating condition in either case, and the air flow into the air chamber at startup In order to prevent the stagnation of the airflow generated by the rebound expansion operation to the original shape by the air suction of the entire filler, the airway inner wall surface is not reduced so that the flow velocity of the airflow generated inside the airway regenerated in the indoor filler is not reduced. No smooth surface, air outflow Air flow from the air outlet / entry hole is provided by providing a concave surface with half the shape of tear drops from the hole toward the airway end, and by providing a plurality of whisker-like projections from the air outflow / inlet to the airway end. Atmospheric pressure expansion impact characterized by the structure of a filler with an inner wall-shaped airway that does not decrease the flow velocity of the air flow when flowing in, and that interferes with the air flow and decreases the flow velocity when the air flow flows out from the air outlet / inlet Mitigation device.
In addition, the second idea is to add a flexible material sheet to the surface to be protected and the surface to be protected provided in the interior of the air chamber, and to multilayer the filler, so that the air chamber is repelled or compressed. Atmospheric pressure expansion characterized by a structure and shape that averages the shape of the deformation of the filler, shortens the expansion and compression time, disperses the impact at the time of impact, and suppresses the movement of air in the filler -Type impact mitigation device.
Next, in the third device, one side is fixed when receiving an impact, and the starter wire with the starter key of the present invention attached to the other side is automatically removed from the main body of the atmospheric expansion shock absorber. The activation key has a hemispherical shape for the activation key, and the wire located at the tip of the automatic closing type exhaust valve having a concave top at the top is the automatic closing type exhaust. By pulling the valve, the outside air flows backward through the self-closing exhaust valve and flows into the air chamber, so that the activation key loses the adsorption power to the bottom of the air inlet hole, and the automatic closing exhaust valve moves forward. Therefore, the mounting position of the starting wire advances, so that it has a shape and structure that can be easily started from all directions, but is sucked by the external suction device when the air chamber is compressed inside the starting key. Air flow inside the activation key Built-in self-closing exhaust valve with a manifold with a concave airflow control wall that halves multiple teardrop shapes to prevent sticking and accelerate exhaust flow velocity, and integrates intake and exhaust mechanisms The key for starting with a characteristic structure and shape has been integrated with an exhaust valve that was previously required to reduce the number of air leaks into and out of the air chamber. It features the structure and shape of the air inlet / outlet hole that controls the air flowing into and out of the air chamber by the activation key holder seal packing, dust filter, vane-type one-way control valve and intake side duct provided on the side. is there.
This activation key is pulled and set in close contact with the packing at the bottom of the air outflow / inlet hole due to the vacuum inside of the air chamber and the suction force of the filler, so that the air chamber is sealed when not in operation. The present invention relates to a structure and a shape of an activation key and an air outflow / inlet hole that form an integral type to be maintained, are light in weight, eliminate a blind spot of operation, and reduce the force required for activation.
The fourth device is an atmospheric pressure expansion type impact mitigation device characterized by a structure and a shape having a vent hole penetrating the air chamber and the filler in order to give the air chamber air permeability.
Next, in the fifth device, when the air chamber is fixedly stored in the air chamber case, and the outer skin and the inner skin, and the air chamber case is fixedly connected, the three-dimensional structure can be constructed at the same time as starting, Even if the air chamber and the filling material in the air chamber are integrated three-dimensional structures that match the shape of the main body, the air chamber and the filling material in the air chamber are stored as a unit in a case that matches the shape of the main body. The structure and shape of an air outlet / inlet with an additional connector that enables easy expansion of the main body by attaching an air chamber coupling device to the connector provided on the outer surface of the air outlet / inlet. It is an atmospheric pressure expansion type impact relaxation device.

According to the first device, when the activation key set in the air outflow / inflow hole during non-operation is separated from the air outflow / inflow hole, the air flowing into the air chamber compressed by evacuation causes the inside of the air chamber to High resilience urethane material that can be compressed and restored to its original shape is released from compression, and the repulsive force instantly expands to its original shape and forms an airway. It is a way to accelerate the inflow velocity of the atmosphere as a way to flow into.
At the time of impact on the air chamber, the filling material receives pressure from the object and the airway is blocked to reduce the air outflow speed to the outside of the air chamber. When the impact on the chamber leaves and the pressure by the object disappears, the filler is restored to its original shape by the repulsive force, so that the atmosphere is sucked and the shape of the air chamber is restored to its original state.
As described above, when the shape and function of the filler changes in the air chamber, when the atmosphere flows in from the air inflow / outflow hole, the compressible filler having repulsive force sucks the atmosphere into the original shape. The airway generated as a shape when repelling and expanding passes through as the path with the least resistance when the air flows in, and generates an air flow, but the filler expands instantaneously as a whole and the inner wall surface of the airway Since the air is sucked from the entire surface of the airway, the airflow generated inside the airway is prevented from stagnation and the flow velocity is not lowered. An airway with an inner wall shape that accelerates the airflow in the center of the airway and prevents the stagnation of the airflow by providing a concave surface with half the teardrop shape, increasing the airway surface area, and generating turbulence near the inner wall of the airway Having a filler structure Atmospheric pressure inflatable cushioning device according to symptoms.
At the same time, by providing a plurality of whisker-like projections from the air outlet / inlet on the inner wall of the airway toward the end of the airway, when the air flows in from the air outlet / inlet, the air flow velocity is not reduced and the air inflow / outflow is reduced. When the airflow flows out of the hole, the atmospheric pressure expansion type impact mitigation device is characterized by a structure of a filler having an inner wall-shaped airway in which the airflow is obstructed and the flow velocity is reduced.
In addition, the concave surface and the plurality of whisker-like protrusions, which are provided on the inner wall surface of the airway and are halved from the shape of the plurality of tear drops, are used when the filler released from compression is instantaneously restored to its original shape by the repulsive force. It also facilitates the generation of airway shapes.
Next, according to the second device, when the atmospheric pressure expansion type impact relaxation device of the present invention receives an impact from outside during operation, the atmosphere filled in the air chamber is instantaneously pressurized and compressed. In this way, a repulsive force is generated, and at the same time, the air inside the air chamber is discharged from the air outlet / inlet while being controlled by the vane-type one-way control valve to absorb the shock. When the air chamber is under pressure, the filler inside the air chamber is also subjected to the impact pressure to compress the airway and suppress the outflow of air to the inside of the air chamber. By adding another material sheet, the filler is multi-layered, thereby suppressing the shape of the filler to be deformed by pressure and having a structure and shape that disperses the impact at the time of impact.
In addition, the present invention adds a thinner and soft separate material sheet to the surface to be protected of the filler, and multi-layers, so that when it receives an impact from the outside, it is filled into the air chamber and compressed under pressure. It has a structure that suppresses the movement of the atmosphere in the air chamber that generates repulsive force and disperses the impact on the surface to be protected, and adds a soft separate material sheet that has different characteristics to the surface to be protected and the surface to be protected. It is an atmospheric pressure expansion type impact relaxation device having a multilayer structure filler having a characteristic structure and shape inside the air chamber.
Next, according to the third device, the activation key is evacuated from the air chamber during standby, and the packing material in the bottom surface inside the air outflow / inlet hole is created by the intake force generated by the repulsion force from the compressed state in the air chamber. As the entire activation key shape of the activation key has a hemispherical shape, it is pulled up by pulling the wire located at the top of the concave self-closing exhaust valve top. It is easy for the activation key to be removed from the air inlet hole by the length of the automatically closed exhaust valve to be pulled up, and has a shape that allows activation from all directions, but at the same time the automatic closure is pulled up The outside air flows backward through the inside of the mold exhaust valve and flows into the air chamber, so that the adhesion force of the activation key to the air inflow hole is lost and the activation can be easily performed.
An automatic closing type having a manifold provided with a concave surface in which a plurality of teardrop shapes are halved for accelerating inhalation sucked by an external suction device when the air chamber is compressed inside the activation key It has a built-in exhaust valve and an integrated intake / exhaust mechanism, which eliminates the need for a separate exhaust valve with a starting key with a unique shape and shape, and reduces air leakage conditions. Atmospheric pressure expansion type characterized by the structure and shape of the air outlet / inlet hole that controls the atmosphere flowing into and out of the air chamber by the provided key holder seal packing, dust filter, vane type one-way control valve and intake side duct It is an impact relaxation device.
Next, according to the fourth device, the atmospheric pressure expansion type impact mitigation device is given ventilation performance, and the outside air is introduced into the protection object without degrading the impact mitigation performance regardless of whether the device is in operation or not. In order to achieve this, an atmospheric pressure expansion type impact relaxation device characterized by a structure and a shape having a vent hole penetrating the air chamber and the filler.
In the fifth device, when the air chamber is fixedly housed in the air chamber case and the outer skin and the endothelium and the air chamber case are fixedly connected, a three-dimensional structure can be constructed at the same time as the activation. Even if the filling material in the air chamber is an integrated three-dimensional structure that matches the shape of the main body to be completed, and the air chamber and the filling material in the air chamber are stored as a unit in a case that matches the shape of the main body Atmospheric pressure characterized by the structure and shape of an air outlet / inlet with an additional connector, which can be easily expanded by attaching an air chamber coupling device to the connector provided on the outer surface of the air outlet / inlet It is an inflatable impact relief device.

The conceptual diagram of the connector and air chamber connection apparatus which are provided in the outer surface of the atmospheric | air flow outflow hole of this invention.

The atmospheric pressure expansion type impact mitigation device of this device is installed in the Depack Rucks 1 used by passengers such as bicycles and motorcycles, hikers, climbers, tourists, attending schools, and commuters. It is a conceptual diagram which shows the state at the time of non-operation | movement at the time of giving equipment, such as a jacket and the emergency mat for sleeping, and FIG. 1 shows one Embodiment at the time of non-operation | movement.
[FIG. 1] is a conceptual diagram of the front surface when not in operation, and the tip of the starting wire 2 is fixed to the top of the automatic closing type exhaust valve 4 when separating the external intake device built in the starting key 3; This figure shows a state in which the activation key 3 is inserted into the air outflow / inlet hole 5 and the intake valve is automatically closed. The air chamber compressed and housed with the filler inside the outer shell and inner skin of the rucksack body, rucksack and harness when not in operation is an integral type, and the activation key 3 is pulled into the atmosphere by pulling the activation wire 2 It is activated simultaneously by detaching from the inflow / outflow hole 5 and covers the head, back, spine, buttocks, chest, neck, shoulders, and side parts during operation.
The rucksack storage part functions as the original storage and transport of the rucksack, and the shape does not change, but the back contact part of the rucksack storage part has an air chamber. An emergency sleeping simple mat 6 that can be optionally activated and is folded and stored is provided between the storage unit and the air chamber as a function of an avalanche-preventing airbag 6 when an avalanche disaster occurs. To fulfill.
The activation key set in the air outflow inlet is drawn in such a manner that a suction force is generated in the filler to be compressed when the air chamber is evacuated and the packing is in close contact with the packing at the bottom of the air outflow inlet. The key cover 7 is fastened with Velcro tape provided on the outer sheath of the harness portion as a safety device for preventing malfunction due to careless handling of the activation wire 2 and activation key 3 when using the rucksack. Is a safety device.
Next, the air outflow / ingress hole cap 8 connected to the back surface of the key cover 7 with a rucksack / harness portion by a shock cord is activated, and the air outflow is performed in order to effectively function as a life jacket for life after the air chamber expands. It is a cap that seals the air chamber by fitting into a connector 38 provided on the outer surface of the entry hole. Basically, the filler that has been restored to its original shape does not absorb water by a material such as high-resilience urethane, but if the air in the air chamber is pushed out by water pressure, there is a possibility of infiltration of water equivalent to the outflow amount of air. Since it is difficult to discharge the invaded water immediately, it is possible to prevent water from entering the air chamber by using the cap 8 when used as a life-saving life jacket, and to function as a buoyant body for a longer time. To fulfill.
It can also be activated by pulling up the activation wire 2 and pulling up only the self-closing exhaust valve 4 when used as a life jacket for lifesaving. After the filling material is restored to its original shape, the self-closing exhaust valve 4 is pushed in again to close the air chamber, and the cap 8 seals the air chamber. Is unnecessary.

[FIG. 2] is a conceptual diagram showing a state during operation when the atmospheric pressure expansion type impact mitigation device of [FIG. 1] is mounted on a depack rucksack 1 having an emergency sleeping simple mat 6; [FIG. One embodiment at the time of operation is shown in FIG.
When the starter wire 2 is pulled with a force exceeding the suction force of the filler that has been compressed by evacuating the inside of the air chamber, the starter key 3 is removed from the air outflow / inlet hole 5 at the time of operation. The air chamber that was evacuated and compressed together with the filler inside the outer skin and inner skin of the sack body, rucksack and harness part was filled with the compressed air inside the air chamber, and the original shape was created by the material repulsive force. It is generated in the same shape as the original shape restored at the same time, and at the same time, it is generated as an air cushion for shock relaxation in the head, back, spine, buttocks, chest, neck, shoulders, side It is.
Further, in FIG. 2, in addition to the emergency operation state of the atmospheric inflation type impact mitigation device of FIG. 1, an optional additional air bag is provided between the rucksack storage portion and when necessary. This shows the unfolded state of the emergency sleeping air mat 6 that can be activated by pulling the starting wire 42 and is folded and stored. At the same time, the emergency sleeping air mat is buried when an avalanche disaster occurs. The function as the prevention airbag 6 is fulfilled.
Note that the air chamber, the filler, the airway, the activation key, the self-closing exhaust valve, the air inflow / outflow hole, the air permeability, etc. during operation in the state of [FIG. 2] will be explained in another figure. .

When the atmospheric pressure expansion-type impact mitigation device of this device is in a non-operating state when it is given a full body impact mitigation function in the form of clothes that can be used by aerial workers, snowmobile / ATV passengers, two-wheeled vehicle passengers, etc. FIG. 3 shows an embodiment of the present invention when not in operation.
The tip of the starting wire 2 shown in FIG. 3 is fixed to the top of the automatic closing type exhaust valve 4 when the external intake device is separated, which is built in the starting key 3. It shows a standby state in which the key 3 is inserted and the intake valve is automatically closed and ready for startup.
The air chamber compressed and accommodated together with the filler inside the outer skin and inner skin of the garment-like body when not in operation is a whole-body type, and the activation key 3 is pulled from the atmospheric outflow / inlet hole 5 by pulling the activation wire 2. It is activated at the same time by detaching, and the impact is greatly reduced with emphasis on the head, neck, shoulders, chest, side, back, spine, buttocks, upper arm, arms, pelvis, thigh, and tibia There is an air chamber.
[FIG. 1] Similarly, the activation key set in the air outflow / inflow hole is that the inside of the air chamber is evacuated and a suction force is generated in the filler compressed by the evacuation, so that the air outflow / inflow Velcro tape is attached to the outer sheath of the harness as a safety device to prevent malfunction due to careless handling of the activation wire and activation key while using the rucksack. The key cover 7 to be stopped is a safety device.

The rear view is a conceptual diagram of the rear view of the device when the device is given a full body impact mitigation function with the outer shape of this device as a garment that can be used by an aerial worker, snowmobile / ATV passenger, two-wheeled vehicle passenger, etc. It is shown in FIG.
In FIG. 3, the activation key 2 is pulled by the force exceeding the suction force of the filler that has been compressed by evacuating the inside of the air chamber, so that the activation key 3 is detached from the air outflow / inflow hole 5. During the operation, as shown in FIG. 4, the air chamber that was evacuated and stored together with the filler inside the outer skin and the inner skin of the garment-shaped main body was filled with the filler compressed in the air chamber. Inhaled and rebounded to the original shape, it expands to the same shape as the original shape restored, and at the same time the head, neck, shoulders, chest, armpits, back, spine, buttocks, upper arm, arms, pelvis This shows a state generated as an air chamber in the head, thigh, and tibia.
Note that the air chamber, the filler, the airway, the activation key, the self-closing exhaust valve, the air inflow / outlet hole, etc. during operation in the state of [FIG. 4] will be explained in another figure.

[FIG. 5] shows an embodiment of the present invention in which one or a plurality of air chambers are fixedly connected between the outer skin and the endothelium of the body shape suitable for the object to be protected and the air chamber, When the activation key is automatically activated by being separated from the air outflow / entry hole due to being fixedly housed in the chamber case and the outer skin and the endothelium and the air chamber case being fixedly connected, or the activation key is When activated by intentionally pulling it away from the air outlet / inlet, and when the self-closing exhaust valve is pulled out from the inside of the activation key, the inner and outer skin, and the air chamber, or As a result, a tension relationship occurs in the positional relationship of the air chamber case, and as a result, a conceptual diagram of a lifeboat that can be used as a large-scale emergency emergency evacuation facility that automatically builds as a three-dimensional structure when it is activated [Figure 5] It is intended.
Emergency evacuation facilities used in the vicinity of the coast due to earthquakes, tsunamis, river floods, typhoons, etc., when the emergency evacuation facility drifts on the sea, it is at the discretion of the user in consideration of falls, turns, rotations and overturns in the sea. Manual activation, or automatic activation when the top of the facility is submerged for a certain period of time, has a restoring effect due to the atmosphere and filler contained in different air chambers below and above the floor of the facility, and the air chamber shape By generating the hull design, an automatic restoration function at the time of capsize is given.
By the way, at the time of the first start-up, the upper half of [Fig. 5] is automatically constructed as an emergency evacuation facility in the event of a disaster, and the floor, wall surface, roof, doorway, and internal partition are all constructed according to the structure of the present invention. Opening and closing windows by partially omitting the air chambers as well as the lighting window 45 and the ventilating hole 43, depending on the air chamber case and air chamber fixed between the outer skin and the inner skin, or the layout of the outer skin and the inner skin. It is possible to easily install the lid 9, the openable / closable window 10, and the shield doorway 44.
Next, in a state where the evacuation facility was swept over the sea due to a tsunami or the like while being used as an emergency evacuation facility at the time of a disaster, the lower part of the hull water line 11 was activated from the floor of the facility at the time of the second activation. Water as a weight flows into the underwater part activated and generated separately by the activation system, and the hull of the hull, endothelium, air chamber, and filler constituting the bottom of the keel 12 is different depending on the amount of air contained in the hull. In this structure, the outer skin, the inner skin, the air chamber, and the filler constituting the shape of the upper part of the water line automatically return to the water line.
In the present invention, the air chamber expands in the same shape as the original shape of the restored filler, as shown in FIG. It can be generated in any shape such as a spherical shape, a cone shape, a cylindrical shape, etc. without being constrained by a simple shape, and is automatically self-supported and constructed by the tension between the outer skin, the inner skin, and the air chamber case.
It should be noted that the state of [FIG. 5] or the connector and the air chamber coupling device in the case of adding a structure are described in [FIG. 19], and the ventilation performance is as described in [FIG. 18] below. It is possible to give a ventilation function to the room itself.

[FIG. 6] is an example of productization and usage as a packaging material according to an embodiment of the present invention. A transport vehicle or a container crashes for some reason when transporting an article, or a load falls during transport. FIG. 6 shows an example of the box case 13 incorporating the atmospheric pressure expansion type impact mitigation device for the purpose of preventing the loss of the product value by mitigating the impact when the above situation occurs.
In the box case 13 with a built-in atmospheric pressure expansion type shock absorbing device shown in FIG. 6, the outer shell has a size and shape adapted to the transport vehicle, container, etc. It has an integrated air chamber that is continuous with the surface, and the outer surface of the box case is made of a material that the outer skin 14 does not have elasticity, and the inner skin 15 of the inner surface of the box case has flexibility and elasticity so that the air chamber is inside the box case. It expands in the direction.
The product to be transported in the box case is stored, and the activation key 3 is pulled away from the air outflow / inlet hole 5 or the automatic closing type exhaust valve 4 built in the activation key is pulled up to activate, and the hexahedron inside the box case is activated. The air chamber is inflated on all sides of the air bag, and the product is supported by the airbag 16 in the box case so that it floats in the box case as a cushioning material that has an impact mitigating ability between the product being transported and the box case. The impact from the outside to the box case 13 is relieved.
In addition, in order to make this situation concrete, since the product to be transported is started after being stored in the box case, there is room for the start-up time. By setting a material with strong repulsive force and a soft material while having a repulsive force on the side surface, it fills the space between the product to be transported in the box case and the box case, and has a buffering capacity to the product to be transported It can be kept soft.
Since this device gains impact mitigation ability by controlling the atmosphere in the air chamber, there is no restriction on the size and shape of the air chamber, and it can also be used for objects with large and complicated shapes. After transport and use, it is easy to store by expanding and compressing the air chamber, and can be used again.

The external shape of this device is a large airbag shape, air bags are installed inside the front and rear bumpers of large vehicles such as buses, trailers, trucks, etc. [Fig. 7] shows a conceptual diagram at the time of operation of a large-sized airbag device that alleviates the impact impact on the vehicle body in the event of a disaster and alleviates the impact on passengers, passengers, and loaded cargo.
Since the atmospheric pressure expansion impact mitigation device of this device uses the atmosphere for rebound restoration to the original shape of the filler inside the air chamber, there is no restriction on the size of the air chamber, so at the time of traffic accident disaster occurrence Even during a collision between vehicles or between a vehicle and a structure, a large-capacity airbag 16 is generated between the vehicles, between the vehicle and a person, or between the vehicle and the structure with a comma starting time of several seconds to reduce the impact. Is.
As a matter of course, the structure of the large airbag 16 is basically the same for the outer skin 14, the inner skin, the air chamber, and the filler. In addition to being able to arbitrarily set the size, air chamber size, starting speed, etc., use the atmosphere as a buffering force in the air chamber. Thus, the air chamber is inflated because the air is sucked when rebounding to the original shape, and the shape and structure of the airway that accelerates the airflow flowing into the filler in the air chamber can be realized.
The sensor unit 17 installed in front and rear of the bumper shown in FIG. 7 is attached to the front and rear bumpers, and when the sensor unit is pressed, the activation key is removed from the air inlet hole, and the space between the bumper and the vehicle body By generating the airbag 16 equivalent to the safety cushion fence from the front, 50% or more of the front surface or the rear surface of the mounted vehicle is covered.
Further, it is easy to construct a system for operating the activation device of the present invention by using a signal of a proximity sensor that is generally used for a vehicle as a sensor.

A conceptual diagram when the filler and the airway in the air chamber of the atmospheric pressure expansion impact mitigation device of the present invention are not operated is shown in FIG. 8 in a cut model mode.
In order to form this state, the duct of an external intake device such as a vacuum cleaner is pushed against the self-closing exhaust valve 4 at the top of the activation key while the activation key 3 is inserted into the air outlet / inlet 5. By applying the air, the self-closing exhaust valve 4 is opened, and the air inside the air chamber is evacuated, whereby the air chamber 18 and the filling material 19 and air passage 20 inside the air chamber are compressed and stored.
At this time, the air in the air chamber is sucked by using an external air intake device such as a vacuum cleaner and exhausted from the air chamber to complete the evacuation, and the duct of the external air intake device is automatically closed. When pulled further away, the exhaust valve is automatically closed, and at the same time the inside of the air chamber 18 is evacuated and the suction force of the filler 19 causes the activation key 3 to be in close contact with the packing 21 on the bottom surface of the air outlet / inlet 5. It is drawn in the form and set.
In addition, the air chamber 18 is sealed while the activation key 3 connected to the activation wire 2 is inserted into the air outflow / inflow hole 5 at the time of non-operation, and the air cannot flow into the air chamber. Further, since the air chamber is evacuated and compressed, the blade-type one-way control valve 22 is positioned in close contact with the fender filter 23 which is the air flow restricting position of the air inflow / outflow hole.
This non-operation time is the same as the standby state in which the atmospheric pressure expansion type impact relaxation device can be activated at any time, and there is no air flow inside the air chamber.
[FIG. 8] is a conceptual diagram of the relational operation and does not indicate the positional relation.

The configuration of the air chamber at the time of operation of the atmospheric pressure expansion type impact mitigation device according to one embodiment of the present invention is shown in FIG. Shown in cut model mode.
In order to form this state, the activation key 3 is pulled away from the air inflow / outflow hole 5, and when the air flows in, the filling material 19 compressed by evacuation inside the air chamber 18 has a material repulsive force of the filling material. In this case, the airway 20 and the air chamber 18 are generated by the restoration of the filler to the original shape, and the airflow is generated by the suction force when the filler 19 is restored. In the air chamber, the concave surface 24 formed by halving a plurality of teardrop shapes provided on the inner wall of the airway of the filler prevents the stagnation of the generated airflow by the suction force when the filler is restored at the time of activation. In order not to reduce the flow velocity, the inner wall surface of the airway is not smoothed, and a concave surface in which a plurality of teardrop shapes are halved from the air outlet / inlet toward the end of the airway, Near the inner wall of the airway By generating turbulent flow, the airway is given a shape that accelerates the airflow in the center of the airway and prevents airflow stagnation, and similarly has a plurality of whisker-like projections 25 from the air outlet / inlet toward the end of the airway It is.
The conceptual diagram of the airway shape characterized by the structure of the filler 19 having the airway 20 of the airflow control inner wall shape is shown in the following [FIG.
[FIG. 9] is a conceptual diagram of the relational operation and does not indicate the positional relation.

The structure of the air chamber when the shock is applied to the air chamber 18 during the operation of the atmospheric pressure expansion shock mitigation device according to one embodiment of the present invention is the operation concept based on the relationship between the filler, the air chamber, and the shape of the air passage 20 As a diagram, FIG. 10 shows a cut model.
When the air chamber receives an impact 41 from the outside in a state where the air chamber 18 is generated as shown in FIG. 9, the air chamber is opened and the air flows in and expands to receive an impact. In addition, the filling material 19 and the airway 20 restored to the original shape are subjected to pressure, and the atmosphere filled in the air chamber is subjected to pressure and becomes an airflow through the airway to flow out of the air outflow inlet / outlet 5 to the outside of the air chamber. However, when the filler 19 and the airway 20 are subjected to pressure, they are temporarily compressed to lose the shape of the airway, thereby restricting the amount of airflow in the air chamber, and at the same time, the vane-type one-way control valve 22 is provided in the air chamber. Since it has a structure that does not rotate in the direction of airflow from the inside, blocking the flow of airflow at a position in close contact with the dust filter 23 results in limiting the amount of outflow of the air inside the air chamber to the outside of the air chamber. Impact on chamber 18 It is intended to give a yield mitigation capability.
At this time, as described in the item [0036], the concave surface 24 having a shape obtained by halving a plurality of teardrop shapes provided on the inner wall surface of the airway 20 of the filler 19 in the air chamber, and a plurality of whisker-like projections 25 acts as an airway inner wall shape that obstructs the airflow and lowers the flow velocity when the airflow flows backward.
The conceptual diagram of the shape of the airway that characterizes the structure of the filler having the airway of the airflow control inner wall shape is shown in [FIG. 11] and [FIG. 12] below.
Further, [FIG. 10] is a conceptual diagram of a related operation and does not indicate a positional relationship.

[FIG. 11] shows that when the air chamber 18 is generated during the operation of the present invention, the filler 19 absorbs and restores the atmosphere when the filler 19 inside the air chamber is rebounded and restored to its original shape. An air flow is generated inside the airway 20 generated in the filler inside the room. In order to prevent this airflow from stagnation and to reduce the flow velocity, the airway inner wall surface is not smoothed, and the air outflow / inflow hole is formed. A concave surface 24 halved from the shape of a plurality of tear drops from the airway to the end of the airway is provided to increase the airway surface area and generate turbulence near the inner wall of the airway, thereby accelerating the airflow in the center of the airway It is a conceptual diagram of the shape which prevents stagnation of.
In addition, as shown in the paragraph [0045], when the filler 19 and the airway 20 are subjected to an impact on the air chamber 18 and the pressure is received, the air filled in the air chamber receives the pressure and is described above through the airway. It is a countercurrent airflow in the reverse direction and tends to flow out from the air outflow inlet to the outside of the air chamber, but in this case, the overflow that occurs is caused by the backflow of the concave surface in which the teardrop shape is halved. This is the inner wall shape of the airway that affects the central part, obstructs the air flow, and reduces the flow velocity.

[FIG. 12] shows that the filling material 19 absorbs and restores the air when the filling material 19 in the air chamber is rebounded and restored to its original shape in a state in which the air chamber 18 is generated during operation of the present invention. An air flow is generated inside the airway 20 generated in the filler inside the air chamber, but since the filler 19 is compressed and stored at the initial stage when the airway 20 is generated, the air on the inner wall of the airway It is a conceptual diagram of the shape which prevents crimping | compression-bonding by providing the some protrusion 25 which has the directionality from an inflow / outflow hole toward an airway end, and facilitates the air inflow at the time of the production | generation of the airway 20.
In addition, as shown in the paragraph [0045], when the filler 19 and the airway 20 are subjected to pressure upon receiving an impact on the air chamber 20, the air filled in the air chamber receives pressure and passes through the airway 20. Is a counter-current airflow in the reverse direction and tends to flow out from the air outflow inlet to the outside of the air chamber. At this time, a plurality of whisker-like projections 25 generated from the air outflow inlet / outlet 5 toward the airway end. It is the inner wall shape of the airway that obstructs the air flow from the reverse flow and reduces the exhaust velocity.

[FIG. 13] is a conceptual diagram of a multi-layer structure filler having separate sheets of soft material having different characteristics on the surface 26 receiving the impact of the filler 19 and the surface 27 to be protected in the air chamber of the present invention. .
When the air chamber 18 receives an impact from the outside during operation, the atmosphere filled in the air chamber is instantaneously pressurized and compressed to generate a repulsive force. The air is discharged while being controlled by the shape of the airway 20 and the vane-type one-way control valve 22 to generate an absorption force that absorbs the impact. In a state in which the air chamber 18 is subjected to pressure, the filler 19 in the air chamber is also subjected to impact pressure to compress the airway 20 and suppress the outflow of air into the air chamber. By adding a soft separate material sheet 28 to the surface and multilayering the filler, the shape of the filler 19 is prevented from being deformed by pressure and the impact at the time of impact is dispersed, and the surface to be protected is more The thin and soft separate material sheet 29 is added to form a multi-layered structure, so that when an impact is applied from the outside, the air inside the air chamber is filled and compressed under pressure to generate a repulsive force. FIG. 5 is a conceptual diagram of a multi-layer structure filler that has a structure that suppresses and disperses an impact on a surface to be protected, and a soft material sheet having different characteristics on the surface to be impacted and the surface to be protected.

FIG. 14 is a conceptual diagram of the activation key 3 and the air outflow / inlet hole 5 of the present invention.
In order to form this state, the duct of an external intake device such as a vacuum cleaner is inserted into the air from the self-closing exhaust valve 4 at the top of the activation key while the activation key 3 is inserted into the air outlet / inlet 5. By evacuating the air inside the chamber, the air chamber 18 and the filler 19 inside the air chamber and the airway 20 are compressed and housed, and the air inside the air chamber is completely evacuated and the duct of the external intake device Is released from the automatic closing type exhaust valve 4 and the exhaust valve is automatically closed. At the same time, the inside of the air chamber 18 is evacuated and the suction force of the filler 19 causes the activation key 3 to enter the air outlet / inlet. The set is completed by being pulled in close contact with the packing 21 on the bottom surface.
The activation key 3 has a shape that allows the activation key 2 to be activated from all directions by the activation wire 2 located at the tip by making the entire shape of the activation key hemispherical. Built-in self-closing exhaust valve 4 having a manifold 30 provided with a concave surface 24 that is formed by halving a plurality of teardrop shapes for accelerating the intake air sucked by the external suction device when the chamber is compressed. It has a characteristic structure and shape integrated with an intake / exhaust mechanism, and has an O-ring 31 on the outer periphery of the activation key that serves as a seal against the air outflow / inflow hole. The shape and structure of the activation key will be described with reference to the operation state shown in FIG. 15, but the self-closing exhaust valve 4 is apparently shown inside the activation key 3 in FIG. 14. It is drawn into the closed state.
The self-closing exhaust valve 4 is also drawn into the upper part of the manifold 30 inside the activation key by the vacuum inside of the air chamber 18 and the suction force of the filler 19 like the activation key 3. 32 is sealed.
The top of the self-closing exhaust valve 4 has a concave dish shape and has a shape that makes the suction force of the external intake device effective.
Next, in FIG. 14, the atmosphere outflow / inlet 5 provided on the air chamber side where the activation key is set is an activation key that makes contact with the activation key 3 in the vicinity of the opening 33 at the bottom of the atmosphere outflow / inlet. It is a conceptual diagram which shows the structure, shape, and positional relationship which have the receiving seal packing 21, the fender filter 23, the blade | wing type | mold one-way control valve 22, and the side duct 34 for intake.

[FIG. 15] is a conceptual diagram showing the relationship between the activation key 3, the air outflow / inlet hole 5, the airway 20, and the air chamber 18 in a state in which the atmospheric pressure expansion shock absorbing device of the present invention is activated.
In order to form this state, the activation key 3 is pulled away from the air outflow / inflow hole 5, and the air flows into the air chamber 18 through the air outflow / inflow hole 5, so that it is compressed by evacuation in the air chamber. The filler 19 is restored to its original shape by the repulsive force of the filler, and the airway 20 and the air chamber 18 are generated. The suction force when the filler 19 is restored accelerates the air chamber generation time. It is a conceptual diagram which shows the structure, shape, and positional relationship which airflow generate | occur | produces in starting.
In this state, the air flowing into the air chamber due to the suction force when the filler 19 is restored passes through the fender filter 23 provided in the air outlet / inlet 5, and the blade-type one-way control is in close contact with the dust filter. When the valve 22 is rotated, airflow is generated, and most of the airflow 20 travels through the airway 20 without resistance. However, in order to prevent the stagnation of the airflow and not to reduce the flow velocity, the airway as shown in FIGS. The inner wall surface has a special shape and structure.

[FIG. 16] shows the outflow of air when the atmospheric pressure expansion shock mitigation device in the activated state shown in [FIG. 15] is activated and the air chamber 18 receives an impact from the outside. FIG. 3 is a conceptual diagram showing a relationship among an entrance hole 5, an airway 20, and an air chamber 18.
In order to form this state, when the air chamber 18 receives an impact from the outside during operation, the atmosphere filled in the air chamber is instantaneously pressurized and compressed to generate a repulsive force, and at the same time, the air outflow The air inside the air chamber 18 is discharged from the inlet 5 while being controlled by the shape of the airway 20 and the vane-type one-way control valve 22 to absorb and absorb the impact.
At this time, the filler 19 and the airway 20 are subjected to an impact on the air chamber 18 and pressure is applied thereto, so that the filler 19 inside the air chamber is also subjected to the impact pressure and the airway 20 is compressed, so that the air flow inside the air chamber 18 is compressed. However, the atmosphere filled in the air chamber receives pressure and becomes a backflow airflow in a direction opposite to the flow of the airflow at the time of activation shown in FIG. Concave shape that is intended to flow out of the air inlet / outlet 5 to the outside of the air chamber and is formed by halving a plurality of teardrop shapes generated on the inner wall surface of the airway 20 from the air inflow / outlet hole 5 toward the airway end. The air flow is obstructed by the reverse flow of the portion 24 and the beard-like projection 25, and the vane type one-way control valve 22 does not rotate in the direction of the air flow from the air chamber. Control the atmosphere A mechanism for absorbing the impact on the air chamber 18 in structure and shape to discharge.
Further, in the present invention, a soft separate material sheet 28 is added to the surface of the filler 19 that receives an impact, and the filler 19 is multi-layered, so that the shape of the filler is deformed by pressure, and the impact when the impact is received. In addition, a thin and soft separate material sheet 29 is also added to the surface to be protected to make it multilayer, so that when it receives an impact from the outside, it fills the inside of the air chamber, compresses it under pressure, and repels it. It has a structure that suppresses the movement of atmospheric air in the air chamber and disperses the impact on the surface to be protected, and adds a soft separate material sheet with different characteristics to the surface to be protected and the surface to be protected. It is a multi-layered filler.
Note that the black arrow indicates the flow of airflow in the air chamber.

[FIG. 17] shows that the atmospheric pressure expansion type impact mitigation device shown in the above [FIG. 16] operates, the shock situation is absorbed and relaxed after the shock is absorbed in the air chamber 18, and the atmospheric pressure expansion type. When the air chamber 18 is compressed and regenerated to the standby state in a situation where the shock absorbing device is regenerated to the standby state corresponding to the emergency start again, the activation key 3 is set in the air outflow / inlet hole 5 and vacuum cleaning is performed. It is a conceptual diagram which shows the state which makes it easy to exhaust the air | atmosphere in the air chamber 18 by using external intake devices, such as a machine.
In order to form this state, with the activation key 3 inserted into the air outflow / inlet hole 5, the duct of the external intake device such as a vacuum cleaner is pressed against the top of the activation key, thereby The self-closing exhaust valve 4 having a concave shape at the top is pulled in the direction of the external intake device by the suction force to open the exhaust valve, and the automatic closing exhaust valve 4 is automatically opened and the atmosphere inside the air chamber is opened. Since the air is evacuated, the air chamber 18 and the filling material 19 inside the air chamber and the air passage 20 are compressed and stored, and the air inside the air chamber 18 is completely evacuated, so that an external intake air such as a vacuum cleaner is used. When the duct of the apparatus is separated from the automatic closing type exhaust valve 4, the exhaust valve is automatically drawn into the upper part of the manifold 30 inside the activation key 3 by the negative pressure in the air chamber and is plugged by the O-ring 32.
The self-closing exhaust valve 4 has a wire at the top, but the top has a concave shape so that the intake force of the external intake device can be used efficiently.
At this time, the activation key 3 also comes into close contact with the packing 21 on the bottom surface of the air outflow / inlet hole due to the vacuum inside of the air chamber 3 and the suction force of the filler 19, and the outer periphery of the activation key The O-ring 31 is pulled in to be positioned and the setting of the standby state is completed, and the dust-proof filter 23 and the blade-type one-way control valve 22 on the atmosphere outflow / inlet 5 are in close contact with the activation key 3. .
When the air in the air chamber is exhausted by an external air intake device such as a vacuum cleaner, a manifold 30 provided with a concave surface 24 that is formed by halving a plurality of teardrop shapes for acceleration inside the activation key is activated. It is characterized by a structure and shape for accelerating the flow velocity of the airflow sucked by the external air intake device inside the key 3 and the compression of the air chamber 18 and the filler 19 is caused by the early compression around the air outflow / inlet hole. The air intake side duct 34 is provided on the bottom surface of the air inflow / outflow hole so as not to disturb the outflow air flow from the room.

[FIG. 18] is a conceptual diagram of a vent hole 35 provided through the air chamber 18 and the filler 19 of the present invention.
In order to provide ventilation performance to the atmospheric pressure expansion type impact mitigation device and to introduce the outside air into the protection target without deteriorating the impact mitigation performance regardless of whether the outside air is operated or not in operation of the present invention, It is an atmospheric pressure expansion type impact relaxation device characterized by a structure and shape having a vent hole 35 penetrating the filler 19. The vent hole 35 is provided so as to avoid the airway 20 portion in the filler 19 of the air chamber 18, and naturally the filler 19 is compressible and has a restoring force to restore the original shape and the restoring direction of the material. Therefore, ventilation performance is ensured even in a standby state where the air chamber 18 is compressed.
Corresponding to the ventilation holes provided through the air chamber and the filling material, the outer skin and the inner skin are made of materials intended for waterproofing, ventilation, ventilation, etc., ventilation / ventilation holes, flaps, zips, etc. Open / close / inflow / exhaust volume control functions, etc. are provided.

FIG. 19 is a conceptual diagram of the connector 36 and the air chamber coupling device 37 provided on the outer side surface of the air outflow / inflow hole 5 of the present invention.
Even if it is like a large-scale emergency emergency evacuation temporary structure by attaching the air chamber connecting device 37 to the connector mounting screw 38 provided on the outer surface of the air outflow / inflow hole 5 by the connector 36, It allows easy expansion of the main unit or unit.
In the present invention, the activation key 3 is separated from the air outflow / inlet hole 5 and the air flows into the air chamber 18 through the air outflow / inlet hole 5, so that the filling that has been compressed in the air chamber by evacuation is performed. Since the material 19 is restored to its original shape by the repulsive force of the filler and the airway 20 and the air chamber 18 are generated, a large-scale disaster that is automatically established and built once it is activated in the integrated air chamber. In the case of temporary structures for emergency evacuation, the air chamber connecting device 37 is not required at the time of activation, operation, or withdrawal, but the air chamber is unitized and stored in the case In this case, the connectors of the unit air chambers are connected by the air chamber connecting device 37 to facilitate installation / removal of the internal partition or the like.
The air chamber coupling device 37 has a connector 36 which is internally threaded at the end, and is fastened to a connector screw portion 38 provided on the outer surface of the air outflow / inflow hole 5. Sealed with a packing 39 on the bottom surface inside the connector.
In addition, the air chamber coupling device 37 basically has three connectors 36 so that it can be expanded or newly installed. If there is an unused connector, the seal cap is attached to the screw engraved inside the connector 36. 40 is screwed in and sealed, or an activation key is inserted to facilitate control.

According to this embodiment, the present invention is an atmospheric pressure expansion type impact relaxation device, and the activation wire is operated with a force exceeding the suction force of the filler that has been compressed by evacuating the inside of the air chamber of the impact relaxation device main body. When the activation key is pulled out of the air outflow and entry hole, the compressed material inside the air chamber is restored to its original shape by the material repulsive force, and the air is sucked in and the air chamber is restored. When the air chamber receives an impact from the outside in the operating state, the air filled in the air chamber is momentarily pressurized and compressed to generate a repulsive force. At the same time, the air inside the air chamber is controlled by flowing out from the air inlet / outlet, so that the impact from the outside is absorbed and relaxed. Generating air chambers, secondary and tertiary Which corresponds to the plurality of shock continue the.
Therefore, since the present invention uses the atmosphere filled in the air chamber for shock absorption mitigation, a gas having a restricted expansion size that fills the general air chamber with a gas cartridge cylinder and expands the air chamber. Unlike inflatable impact mitigation devices, the necessary and sufficient air chamber size can be arbitrarily set according to the size and weight of the target to be mitigated, but the outflow and inflow of air into the air chamber In order to create an air chamber of a shape and size tailored to the purpose of use, it is necessary to create a shape and structure that allows the inflow of air necessary to generate an emergency or an effective amount of air outflow to absorb shocks. It is given to the activation key, atmospheric outflow hole, air chamber, filler, airway, etc. in the present invention, and it is possible to control the amount and speed of the outflow inflow into the air chamber.

According to this embodiment, in the present invention, when the activation key is released from the air outflow / intake hole, the packing material compressed in the air chamber is released from compression by the inflowing air, and at the same time, due to the material repulsive force. In addition to restoring and generating the original shape, the shape of the airway is generated. At the time of restoring to the original shape, the atmosphere is sucked into the air chamber and the air inflow speed into the air chamber is accelerated.
In addition, when the air chamber is impacted, the filler receives pressure from the object, and the airway is deformed and blocked, thereby reducing the flow rate of air out of the air chamber and reducing the flow rate. is there.
Due to this structure, the present invention enables control of the airflow into and out of the air chamber as an atmospheric pressure expansion type impact mitigation device. As described above, when the shape and function of the filler changes inside the air chamber, In addition, when the air flows in from the air outlet / inlet, the airway generated as a shape when the compressible and repulsive filler material sucks in the air and repels and expands to the original shape, when the air flows in Although it passes as the path with the least resistance and generates airflow, the filler expands instantaneously and sucks air from the entire inner wall of the airway, so the stagnation of the airflow generated inside the airway In order to prevent the flow velocity from being reduced, the inner wall surface of the airway is not smoothed, and a concave surface in which a plurality of teardrop shapes are halved from the air inflow / outlet to the end of the airway, Inside the airway By generating turbulent flow in the vicinity of the surface, the airflow at the center of the airway is accelerated to give an inner wall shape that prevents stagnation of the airflow. When the airflow flows from the air outlet / inlet, the airflow velocity is not reduced, and when the airflow flows out of the air inflow / outflow hole, the airflow is obstructed and the airflow is reduced by the inner wall-shaped airway. It is possible to control the inflow and outflow of air to the inside.
In addition, the concave surface and the plurality of whisker-like protrusions, which are provided on the inner wall surface of the airway and are halved from the shape of the plurality of tear drops, are used when the filler released from compression is instantaneously restored to its original shape by the repulsive force. It also facilitates the generation of airway shapes.

According to this embodiment, the gas expansion type shock absorbing device that expands the air chamber by filling the gas chamber with gas from the gas cartridge cylinder expands and collapses the expanded air chamber in terms of strain surface area. In this state, the impact from the outside is relieved by the repulsive force of the air chamber pressure. [0011] The conventional atmospheric pressure expansion shock absorber of [0011] is also used in the inner and outer air chambers of the inner valve. The structure reduces the impact from the outside by the difference in internal pressure and the repulsive force of the fillers having different densities in the inner chamber and the outer chamber.
However, in many cases under the conditions of use, a mechanism that absorbs an impact has a higher impact mitigation ability than an impact that repels the impact. In addition, when the repulsive action occurs, the repulsive force generated by the impact mitigation device after receiving the first impact may cause a new two or three step collision condition. .
Therefore, the atmospheric pressure expansion type impact mitigation device of the present invention solves the problem by having a structure that absorbs the impact by letting out the pressure of the impact received by the air chamber from the outside while controlling the atmosphere from the air chamber. It is.

  According to this embodiment, the present invention is a multilayer structure having a separate sheet of soft material having different characteristics on the surface subjected to impact of the filler and the surface to be protected. By adding a material sheet and multilayering the filler material, the shape of the filler material that is deformed by pressure is suppressed, and the impact at the time of impact is dispersed. By adding a multi-layer, it is possible to suppress the movement in the air chamber inside the air chamber that is filled in the air chamber and compressed by receiving pressure when it receives an impact from the outside, and is applied to the surface to be protected. It has a structure to disperse the impact, and the impact is dispersed by controlling the movement of the atmosphere inside the air chamber by adding a separate soft material sheet with different characteristics to the impact receiving surface and the surface to be protected. .

  According to this embodiment, the activation key of the present invention is that the activation key is evacuated by the suction force of the filler inside the air chamber and the suction force of the filler when the air chamber is compressed. It is in close contact with the packing on the bottom surface of the air outflow / inlet hole, and is drawn in a form that is positioned by the O-ring on the outer periphery of the start key, and is in close contact with the seal packing on the bottom surface of the air outflow / inlet hole. It is in close contact with the dust-proof filter and blade-type one-way control valve on the air outflow / inlet side, and by making the overall shape hemispherical, it has a shape that can be activated from all directions by the wire located at the tip A concave surface having a shape that halves a plurality of teardrop shapes for accelerating the intake air sucked by the external suction device when compressing the air chamber inside the activation key is provided inside the activation key. Built-in self-closing exhaust valve for separating the external intake device having a concave top that effectively uses the suction force of the nifold and the external intake device, and integrating the intake / exhaust mechanism into the atmosphere in the air chamber Air leak conditions are reduced by using a single device that flows in and out.

  The air outlet / inlet provided on the air chamber side of this embodiment has a key holder seal packing for activation, a dustproof filter, a vane-type one-way control valve, and a side duct for intake air. When the air in the air chamber is exhausted by an external air intake device, etc., the air in the air outlet / inlet is not compressed because the compression of the air chamber and filler does not disturb the outflow air flow from the air chamber due to the early compression around the air inflow / outlet. Air intake and exhaust side ducts are provided on the bottom of the room in addition to the air inlet / outlet holes to secure a space for airflow to pass through, and with the activation key set, the air is released from the self-closing exhaust valve when the air chamber is compressed. It facilitates the exhaust of the airflow when exhausting.

The air outlet / inlet provided on the air chamber side of this embodiment has an activation key receiving seal seal, a dustproof filter, a vane-type one-way control valve, and an intake side duct. When operating outside the hole, the air that is compressed in the air chamber is released from compression by the flowing air, and at the same time, the air is sucked into the air chamber when it is restored to its original shape by the material repulsion However, after the dust mixed in the outside air is stopped by the dustproof filter, the air flowing into the air chamber by the suction force is rotated in the direction in which the blade type one-way control valve sucks to control the airflow. .
The vane-type one-way control valve does not rotate when the atmosphere flows out of the air chamber, thereby reducing the air outflow speed to the outside of the air chamber and reducing the flow rate.

According to this embodiment, the start key, the air outflow inlet, and the control valve constituting the starter of the present invention are simple in shape, thin structure, and lightweight, so that the motorcycle, trike, snowmobile, jet ski in the usage environment can be used. The balance of work and fatigue during use of clothing-like bodies worn by passengers of vehicles and ships, altitude workers, anglers, parachute divers, skydivers, hang gliders, snowboarders, skateboarders, climbers, etc. It provides an excellent effect on the degree.
Since the conventional gas expansion type impact mitigation device uses a gas cartridge cylinder, not only the structure of the starter part is required to be structurally rigid, but also an air separator including a gas cartridge cylinder and an opening spring. Concentrated objects are concentrated, and there is a problem with the weight balance during use and the fatigue level at the time of use. At the same time, the size of the air bag increases and the gas cartridge cylinder and the starting device also become heavy. It was something that had trouble. This also applies to models with built-in electric fans and batteries. The more powerful the electric fans and batteries, the more weight increases, and the air chamber expansion speed is compromised to avoid this. There was a problem. Therefore, as a result, cyclists and climbers who require full body movement, altitude workers who require a balance of altitude, motorcycles, tricycles, snowmobiles, jet skis and other passengers, parachute divers, skydivers, It has been pointed out that there is a problem in practicality when using hang gliders, snowboarders, skateboarders, etc., and the present invention solves the problems without affecting the impact mitigation ability and the operating time.

As described in [0062] above, the activation key, the air outflow inlet, and the control valve constituting the activation unit of the present invention are simple in shape and structure, and are light in weight. Thus, it is possible to start even if the force required for starting is small.
The conventional gas expansion type impact mitigation device is equipped with a needle ball for opening the automatic starting device that opens the sealing plug of the gas cartridge cylinder, and the spherical ball key that holds the cylinder pressed by the spring is released to start. This requires a force of about 3 kg, and this is for motorcycles, walkers, wheelchair users, etc. Or when it was a lightweight object like a walking training device, there was a problem that it could not start. The present invention solves that problem, and enables easy activation even if the object to which the activation cable is attached is lightweight.
As described in [0059], the activation key of the present invention is as follows. In the standby mode, the activation key is evacuated by the suction force of the filler inside the chamber and the suction force of the filler. It is in close contact with the packing at the bottom of the air inlet / outlet hole, and is pulled in such a way that it is positioned by the O-ring on the outer periphery of the starting key, but basically it is not a structure that maintains a standby state with a mechanical mechanism. The force required to pull out the activation key at the time of activation can be easily changed by selecting the amount of friction to the inner wall of the air outflow / inflow hole according to the material of the O-ring and the amount of crushing.
In order to prevent the activation key from operating incorrectly when the present invention is not operated, the portion where the activation key is exposed even in the case of a garment-like skin or other shapes In addition, the lid-like cover of the pocket is fastened with Velcro tape, which can be easily solved.

The conventional gas expansion type impact mitigation device, which expands the air chamber by filling the gas chamber with gas from a gas cartridge cylinder, is structurally inactive except for models that can grasp the state of the air chamber by some sensors. Sometimes there is a problem that the fact that the shock-absorbing ability is lost until the time of operation cannot be found because there is no change in the appearance and the normal operation of the airbag breakage or the starter malfunction, and the gas cartridge cylinder product defect etc. there were.
In order to solve this problem, the present invention easily shows that if the air chamber, the activation key, etc. are damaged, the air chamber expands even when it is not in operation, causing some problem in the mechanism. It is possible to recognize.
Of course, even if the air chamber and the activation key are damaged and the air chamber expands when it is not in operation, the atmospheric pressure expansion shock mitigation device of the present invention does not lose the impact mitigation capability. This is a solution to this by a simple mechanism.

The conventional atmospheric expansion impact mitigation device [0011] uses a replaceable screw-in lid and a hook-type hook-shaped wire guide to operate the key 180 degrees in front of the key body, which is unpredictable in the event of an accident. The corresponding shape eliminates the blind spots of operation and reduces the starting force by using seal tape, but it depends on the rider of a vehicle such as a motorcycle, an altitude worker, or other protected subjects. As for the actual situation of the accident, there are many start timings when the wire angle is more than 180 degrees in front of the key body, and when twisting phenomenon occurs, and the opened seal tape prevents the air flow into the air chamber [0012] is the first problem at the time of start-up because the hemispheric start-up key is easily unlocked from the air outlet by the shape having a ring-shaped protrusion. The air flow from the floor was facilitated and the operation of the key 180 degrees in front of the key body was ensured, but the angle between the ring-shaped protrusion and the wire mounting part was shallow, and activation from the side of the activation key However, the activation key of the present invention provides a structure in which the automatic closing type exhaust valve is pulled out from the inside of the activation key and the wire mounting part advances in the first stage at the time of activation. This solves the problem by extending the distance between the air outflow hole and the wire mounting portion and making it possible to cope with an angle of 180 degrees or more on the front side of the key body.
As a matter of course, even when the automatic closing type exhaust valve is pulled out from the inside of the activation key, the atmosphere flows back into the air chamber through the inside of the automatic closing type exhaust valve, and the second stage Thus, the activation key that has lost its adsorption power to the inside of the air chamber can be easily removed from the air outlet / inlet.

In addition, when the atmospheric pressure inflatable impact mitigation device of the present invention is used for emergency evacuation tents, emergency inflatable lifeboats, life jackets / emergency devices, avalanche airbags, safety cushion fences, etc. Pull the wire manually without automatically operating it, and even when the automatic closing type exhaust valve, which is the first step above, is pulled out from the inside of the activation key, it is released from compression by the atmosphere into which the filler inside the air chamber flows. At the same time, the air chamber expands because it is restored to its original shape by the material repulsive force.
When the purpose of use is considered to be submerged, such as emergency evacuation tents, emergency inflatable lifeboats, life jackets, and emergency life-saving equipment, the purpose is necessary assuming the use environment including waterproofing of the outer skin and endothelium. Of course, the material and the manufacturing method can be selected, but after the expansion of the air chamber as described above, the automatically closed exhaust valve is pushed into the activation key to seal the air chamber and complete the buoyancy body. Therefore, it is possible to easily secure various functions with a simple operation.
In the present invention, after the expansion of the air chamber, the activation key loses the force to adhere to the packing on the bottom surface of the air outflow / inlet hole, so the activation key is not prepared by the cover of the pocket described in [0063]. However, the expansion state of the air chamber is naturally maintained even if the activation key is removed from the air inflow / outflow hole due to some reason.
In addition, if the material and manufacturing method required for the purpose are selected assuming the use environment such as waterproofing for the outer skin / endothelium, the air outlet / inlet hole on the air chamber side and the air outlet / inlet mounting hole provided in the outer skin should be provided. By sealing, the outer skin, endothelium, and air chamber become airtight, and the operating state is more efficiently maintained.

Cyclists and climbers who require full body movement, altitude workers who need a balance of altitude, motorcycles, trikes, snowmobiles, jet skis and other passengers, parachute divers, skydivers, hang gliders, snowboarders For skateboarders, gait trainers, wheelchair users, etc., the conventional gas expansion shock absorber and atmospheric pressure expansion shock absorber are of course in the presence of an air chamber accommodated between the outer skin and endothelium. When not in operation, the ventilation performance is significantly hindered. When the outside air is hot, the temperature of the internal environment where the object to be protected is placed, as well as the heat generated by the body to the outside even when the outside air is cold. It was difficult to discharge.
The atmospheric pressure expansion impact mitigation device of the present invention provides this problem by providing a vent hole that penetrates the air chamber and the filler in the air chamber and the filler, so that the impact can be applied regardless of whether the device is in operation or not. This solution solves the problem by allowing the introduction of external air to the object to be protected without deteriorating the mitigation performance and providing ventilation performance for discharging the internal heat to the outside.
Naturally, the present invention is provided with a vent hole that penetrates the air chamber and the filler as described above, and a ventilation opening that can be opened and closed on the outer skin / endothelium is provided at a required position, or the material is waterproof and breathable. Ventilation performance can be easily obtained by selecting a material or selecting a material with excellent breathability according to the intended use of the present invention.
In addition, as shown in [0066], when the purpose of use is to consider submergence such as emergency evacuation tents, emergency inflatable lifeboats, life jackets and emergency lifesaving tools, By attaching and processing the airway for ventilation connecting the ventilation opening that can open and close the outer skin and endothelium of waterproof material in the air hole that penetrates the air chamber and the filler, the air outflow inlet mounting hole provided in the outer skin is sealed, The space between the outer skin and the inner skin and the air-tight state of the air chamber are secured, and it has the function of impact mitigation and buoyancy body, but it is easy to give the necessary ventilation performance to the necessary place of use purpose It is.
At this time, depending on the purpose of use of the present invention, the space between the outer skin and the endothelium and the inside of the air chamber of the entire product incorporating the atmospheric pressure expansion type impact mitigation device of the present invention should be secured, or It is possible to intentionally select whether the space between the outer skin and the endothelium and the airtight state of the air chamber interior are to be partially secured at the required location, or whether only the air chamber interior is to be secured. It does not affect the impact relaxation performance.

According to this embodiment, when one or a plurality of air chambers of the present invention are fixedly connected at a position where a three-dimensional structure can be formed between the outer skin and the inner skin of the main body according to the object and purpose to be protected, Alternatively, since the air chamber is fixedly housed in the air chamber case and the outer skin, the inner skin, and the air chamber case are fixedly connected at a position where a three-dimensional structure can be formed, the activation key is separated from the air outflow hole. In either case, when the start key is deliberately pulled away from the air outflow hole, the auto close type exhaust valve is pulled out from inside the start key, The expansion of the air chamber causes tension in the positional relationship between the inner skin and the outer skin, and the air chamber or the air chamber case, thereby automatically constructing a three-dimensional structure.
In the present invention, the shape of the expansion of the air chamber is that the packing material compressed together with the air chamber inside the air chamber sucks the atmosphere as described above and rebounds and restores to the original shape, thereby restoring the air chamber. Since it expands to the same shape as the original shape of the material, the shape of the air chamber can be generated in any shape such as a sphere, hemisphere, cone, cylinder, U shape, etc. At the time of generation, the outer skin and endothelium, air chamber, Alternatively, it is automatically built by the tension between air chamber cases.
Further, as shown in [0067], according to the purpose of use, the space between the outer skin and the inner skin and the airtight state in the air chamber of the entire product incorporating the atmospheric pressure expansion type impact mitigation device of the present invention are secured. In addition, it is necessary to combine the choice of whether the space between the outer skin and the endothelium and the airtight state of the inside of the air chamber are to be partially secured or the airtight state of the air chamber only is secured Intentional selection for constructing a three-dimensional structure having a shape is possible, and any of them does not affect the impact relaxation performance.
As an example of configuring the above as a three-dimensional structure, since the shape of the air chamber and the filler is the main body shape, the position where the outer skin contacts the air chamber or the air chamber case is perpendicular to the compression / restoration direction. The linear structure is fixed at the same position, and the endothelium is also fixed, so that when the air chamber expands, the three-dimensional structure automatically becomes self-supporting due to the tension relationship between the outer skin and the endothelium, the air chamber, or the air chamber case. Is built. Of course, the above is for ease of understanding the tension relationship between the outer skin and the endothelium, the air chamber, or the air chamber case. In practice, everything is fixed and set according to the purpose of use. By pulling the valve away from the air outflow inlet / outlet or pulling out the self-closing exhaust valve from the inside of the activation key, the three-dimensional structure is automatically established and constructed.
Because of the above, the air chamber and the packing material inside the air chamber are placed in the air chamber case as a cylindrical unit whose compression / restoration direction is the entire outer periphery.・ It is an easy method to compress and restore large areas such as floors.
Needless to say, large-scale disaster countermeasure temporary structures and emergency evacuation tents, etc., having the mechanism and structure of the present invention have not only the impact mitigation ability, but also weather resistance, regardless of the installation environment. The construction worker can be installed alone, does not require any other blower or power supply, and always maintains a fully expanded state after generation.

[0068] As shown in [0068], when the air chamber of the present invention is fixedly connected between the outer skin and the inner skin of the main body according to the object to be protected and the purpose, the air chamber is stored in the air chamber case When the outer skin, the endothelium, and the air chamber case are fixedly connected, the atmospheric expansion shock absorber of the present invention can be used between the outer skin, the inner skin, the air chamber, or the air chamber case when one or more air chambers are in operation. The three-dimensional structure is automatically constructed in a tension relationship, and the three-dimensional structure according to the shape of the main body where the filling material in the air chamber is completed by the air chamber coupling device of the present invention, the air chamber and the expansion connector In the case of a structure, it is easy to add a mechanism that can be started simultaneously. Room connection The in which easily allow interlocking with the body extension by attaching.
The expansion connector is provided on the outer surface of the air outflow inlet, and can be installed by screwing the air chamber connection device. After the air is generated, the atmosphere does not flow out unless the air chamber receives pressure from the outside and receives pressure from the outside, so the air chamber coupling device is activated simultaneously with the unit type air chamber and the internal partition expansion unit air chamber.・ Mainly used for simultaneous compression.

  This device has an air chamber that encloses a multi-layered packing material that is evacuated and compressed and stored between the outer skin and the inner skin of the body shape according to the object and purpose to be protected as an atmospheric pressure expansion shock relaxation device. Single or multiple chambers are provided, and when activated, the starting key is pulled away from the main body, so that the air flowing into the air chamber can be compressed into the original shape while the packing material that can be compressed in the air chamber and has a resilience to the original shape absorbs the air. When restoring the air chamber, the air flowing into the air chamber through the air outlet / inlet is accelerated and sucked from the airway having a characteristic shape provided in the filler, and the air chamber is instantaneously restored to its original shape. At the time of impact to the air chamber, the pressure inside the air chamber is released while restricting the air that flows out of the air chamber through the air outflow inlet / outlet due to the impact pressure by the shape of the airway and the blade type one-way control valve By reason It is a device that absorbs and relieves shocks to the human body, articles, etc., and is an atmospheric pressure expansion shock relieving device that restores the shocks after absorbing and relieving them many times and maintains the air chamber in a fully expanded state. As a matter of course, it also functions as a buoyancy body or the body of a three-dimensional structure, and since there is no restriction on the capacity and shape of the air chamber because air is used for expansion of the air chamber, there are no restrictions on motorcycles, trikes, snow Use as a body-like impact mitigation device worn by mobile and jet ski vehicles and ship occupants, altitude workers, anglers, parachute divers, skydivers, hang gliders, snowboarders, skateboarders, climbers, etc. Emergency evacuation tents, emergency inflatable lifeboats, large bumper airbags for vehicles and people, Jacket and emergency life-saving equipment, are those which enables a wide range of use in a wide range of products that require air bag for the avalanche, safety cushion fence, a large air chamber and the like.

The atmospheric pressure expansion shock mitigation device of the present invention is a situation in which after the shock is received and the shock is absorbed and relaxed, the danger situation goes away and the atmospheric pressure expansion shock mitigation device is restored to the standby state corresponding to the emergency start again. When the air chamber is compressed and regenerated to the standby state below, the activation key is set in the air outlet / inlet, and it can be easily and instantly performed by using an external air intake device such as a vacuum cleaner that is normally used in ordinary households. The air in the air chamber can be exhausted. In order to form this state, the suction force of the external air intake device is pressed by pressing the duct of the external air intake device such as a vacuum cleaner against the top of the start key while the activation key is inserted into the air outlet / inlet. As a result, the self-closing exhaust valve having a concave top at the top is drawn toward the external intake device to open the exhaust valve, and the self-closing exhaust valve is automatically opened, and the atmosphere inside the air chamber is opened. Since the air is evacuated, the air chamber, the filler inside the air chamber, and the airway are compressed and stored. The air inside the air chamber is completely evacuated, and the duct of the external suction device such as a vacuum cleaner is automatically used. When the valve is pulled away from the closed exhaust valve, the exhaust valve is automatically drawn into the upper part of the manifold inside the activation key due to the negative pressure in the air chamber and is blocked by the O-ring.
At this time, the activation key is also in close contact with the packing on the bottom surface of the air outflow / inlet hole due to the vacuum inside the air chamber and the suction force of the filler, and the O-ring on the outer periphery of the activation key It is pulled in in a positioned form and pulled in close contact with the seal packing at the bottom of the air outflow / inlet hole to complete the setting of the standby state. Conventional gas expansion type shock mitigation device and compressed air filling type shock mitigation device However, the technical skill is required for the user in the cartridge cylinder, set, airbag folding, etc., and there is no means for confirming that the set in the standby state has been performed correctly.
The present invention solves this problem and makes it easy for the user to regenerate the product incorporating the atmospheric expansion shock absorber to the standby state. When there is no external suction device such as a vacuum cleaner, It is also possible to manually hold the air chamber and discharge the air inside the air chamber.

The atmospheric pressure expansion type impact mitigation device of the present invention is provided with an automatic closing type exhaust valve integrally in the activation key, and does not have a dedicated exhaust valve.
As a result, the atmosphere flows into and out of the air outlet / inlet only, reducing the possibility of air flow into the air chamber due to a sealing leakage problem when the air chamber is compressed, that is, in the standby state, and facilitating user maintenance. At the same time, one part process is omitted in the product production process.
In addition, if air leaks due to air leakage from the activation key / atmosphere outflow / entry part or the air chamber is damaged due to some reason, the filling material in the air chamber should be restored to its original form immediately. Therefore, it is possible for the user to immediately detect and confirm the occurrence of the trouble by visual inspection, and naturally, the shock mitigation ability is not lost even when the trouble occurs.

[0072] When the trouble shown in [0072] occurs, the conventional gas and compressed air inflation type impact mitigation device mitigates the impact because the airbag does not inflate in any of the cartridge cylinder trouble, the starter trouble, and the airbag damage trouble. There is a problem of losing capacity, and in the model that presses the atmosphere into the airbag with a battery-driven blower, the airbag is installed in the same way as the gas expansion shock mitigation device in any case of battery, motor / blower trouble, or airbag damage trouble. There is a problem that the impact mitigation ability is lost because it does not expand. The conventional atmospheric pressure expansion type impact mitigation device of [0012] is filled when the air chamber receives an impact from the outside although the air chamber expands when the air chamber breaks. The atmosphere in the material easily flows out from the damaged part of the air chamber, and the impact mitigation ability is improved. Those portions that bear on were many.
In the atmospheric pressure expansion shock mitigation device of the present invention, even when the air chamber is damaged due to some factor, the air inside filler has a multilayer structure and the impacted surface and the inside of the air filling material on the protection target side When airflow flows out from the inside of the filler due to the fact that the movement of the atmosphere is suppressed and that the airway inside the filler has a concave surface that is half the shape of a plurality of teardrops and a plurality of whiskers Is a structure in which the air flow is interrupted and the flow velocity drops, and the impact mitigation ability can be utilized not only the material repulsive force of the filler, but also the flow of the air flow to the outside generated by the compression of the air inside the filler, Even when the impact mitigation device is activated at the same time when a trouble occurs, it is possible to give safety measures to the products etc. described in [0070] as a device that protects the user from impact without greatly losing the impact mitigation capability with a simple mechanism. .
It should be understood that the present invention can be used even when the air chamber is damaged, even if the air chamber interior material is restored to its original shape and subjected to multiple impacts from the outside. Each time the impact leaves, the filler is restored to its original shape and does not lose its impact mitigation ability.

This device, when configured as a clothing-like main body with a built-in atmospheric pressure expansion impact mitigation device or a rucksack-shaped main body, has a structure that enables easy activation even if the object to which the activation cable is attached is lightweight, and activation Because of the light weight of the start-up key with built-in self-closing exhaust valve and the air outflow / inlet hole, which has a simple shape and structure, the whole body movement that could not use the conventional gas expansion shock absorber is necessary.
