The present invention relates to a safety device having an inflator, and more particularly, to a safety device equipped with an inflator at an industrial site, a horse racecourse, and other places where a fall accident may occur, Such as an airbag or a safety jacket, connected to a safety device, such as an airbag, to protect the user from impact.

Among the industrial accidents occurring in the domestic industrial sites, fall accidents are included in the top three types of accidents as well as stenosis and evacuation accidents. The fall of the construction industry has been widely known and the measures have been taken in the first place. However, the fall in the manufacturing industry has been neglected because of the risk of falling due to the use of ladders, roofing work, Is often performed to increase the risk of a fall accident.

In the case of industrial sites, although industrial accidents are constantly occurring, the countermeasures against accidents have been made, but there is no countermeasure against safety accidents in daily life such as sports and leisure.

Especially, in the case of horse riding, motorcycle, and cycling, it is possible to protect the head by the helmet but there is a lack of protection against the body, and there is a risk of serious injury in the event of a fall.

As a result, a personal protective gear has been developed to protect motorists and riders such as motorcycle riders. The personal protective equipment is designed to prevent or reduce the damage of the human body by inflating the protective equipment such as the airbag in the dangerous situation. When the accident occurs in the vehicle or leisure activities, the compressed gas is instantaneously discharged and injected into the airbag or life jacket . When the compressed gas is injected, the airbag or safety protective jacket swells instantly to protect the user from the surrounding environment.

This provides a comfortable fit that is not significantly different from a safety belt used in a general industrial field, and can be worn by a user like clothes. In addition, by coupling the wearable airbag 110 having the inflator to the safety belt, the compressed gas can be released to the airbag in an emergency, thereby preventing the user from being fatal. The living body signal sensing device 120 measures at least one of the user's pulse, blood pressure, electrocardiogram, body temperature, blood sugar level, respiration signal, and body temperature, and transmits the living body signal information to the wearable airbag 110 .

The biological signal sensing device 120 is a device that can be worn by the user similar to the wearable airbag 110, but may be preferably attached to the wrist, arm, leg, ankle, and the like.

Bluetooth, NFC, Wi-Fi, zigbee, Li-Fi, etc. may be supported for communication between the bio-signal sensing device 120 and the wearable airbag 110, but Bluetooth may be preferred. However, the present invention is not limited to a single technology, but can also support short-range wireless communication to be developed in the future.

The wearable airbag 110 includes a signal processing unit 111 having a detection sensor, an inflator 112 for discharging gas when a trigger signal is generated by the signal processing unit, And a seal (114).

The detection sensor 111 includes a fall detection module for detecting a change in slope or gravitational acceleration and digitizing the data, and a data logger (black box) for storing the change value.

Further, when an emergency signal is received, an alarm signal can be transmitted to the electrical primer of the inflator 112. [ In an inflator in which an ignition signal is transmitted, for example, a fuse installed in the electric primer is connected to a conductive line to generate electric spark, thereby detonating a gunpowder installed in the electric primer. The air expansion pressure and explosive debris from the explosion of gunpowder are applied to the upper piston.

The piston is installed at the upper end of the electrical primer and receives the pressure due to the explosion of the explosion, and moves instantaneously and rapidly upward. At this time, the perforation pin coupled with the piston also moves upwards to puncture the gas cartridge.

When the gas cartridge is punctured, the compressed gas inside is released and flows out to the gas supply port. Accordingly, the protection device such as an air bag connected to the gas supply port is instantaneously and rapidly blown, so that the user can be protected by an external impact.

In another example, if the upper end of the piston is formed into a sharp-pointed shape, the piston functions simultaneously as a perforation pin, and thus it is not necessary to additionally install a tread. In this case, the piston is subjected to the air expansion pressure when the explosive explosion is caused by the electrical stimulation, and at the same time, it converts the gas cartridge into a physical force for puncturing the gas cartridge. In other words, it acts as an intermediary for converting electrical signals into physical forces. The end of the piston may be formed in a pointed shape so that a hole or groove is formed at the center.

The air distributor 113 is disposed around the gas cartridge connected to the inflator and functions to disperse the gas cartridge into the entire air bag air chamber 114 evenly when the gas cartridge is discharged and the gas is instantaneously released.

The airbag air chamber 114 functions to protect the user from an external impact when the inflator is actuated by an aerial signal, so that the gas blows up instantly and quickly due to the release of gas compressed in the gas cartridge. The airbag air chamber 114 according to the present invention is characterized in that the weight and the surface area are simplified so as not to be inconvenient for a normal life even when the user wears it. In addition, it is formed in the form of a band folded out on the outside so as not to exceed the width of the general safety band, so that it is free to move when worn and provides a wear convenience which is not different from a safety band used in general industrial fields. When compressed gas is discharged by an external impact, the volume of the airbag air chamber 114 folded inwardly outside the safety band is increased, and the discharged air is stored therein. At this time, the user's neck, thorax, vertebra, Thereby protecting the user from external shocks. In addition, the airbag air chamber 114, which can protect the head part, can be folded or attached to the neck wrapping part to protect the head.
