Description

Air Bag for Use in Escaping Use

The present invention relates to a rescue device, and more particularly, to a rescue device for drop suitable for use in a situation that requires evacuation to the lower side, such as a building or a sinking ship in the fire.

When a fire occurs in a high-rise building, the flames are often transmitted to the upper and lower via elevator passages or stairs, so the emergency or emergency escape paths often become useless. In such a case, even though the rescue ladders are used to rescue by using an elevated ladder of a fire truck, it is very difficult to rescue a large number of lives in a short time by using only an elevated ladder. Helicopters are also used to rescue, but helicopters can only be rescued if the evacuator has escaped to the rooftop, and people are forced to move to the rooftop when the escape route is blocked by flames as the fire progresses for a certain period of time. impossible. In low-rise buildings, rescuers may install air mats on the ground and induce evacuators to escape through windows, but in high-rise buildings, it is very difficult for the evacuator to aim and fall down the air mat correctly. The method is also very dangerous.

Accordingly, when a fire occurs due to spontaneous ignition or terror in a high-rise building, the terrible scene where people who failed to evacuate at the initial stage could not endure the fire and finally send it to the ground has been reported many times through broadcasting.

Several drop aids have been suggested for use in fires in high-rise buildings.

For example, Korean Utility Model Registration No. 362154 (designated name: Emergency drop safety clothing) is a cover / parachute composite device that allows a small parachute to expand while the button applying the airbag principle expands when a button is pushed out from a high place. Presenting. However, it is difficult to realistically expect that the general public who has not been systematically trained for a long time properly uses the drop mechanism in an emergency situation.

On the other hand, Korean Patent Publication No. 2003-96996 (name of the invention: life-saving equipment for air escape using the air cushion) is equipped with an airbag including an inflator for generating air or gas in a life jacket worn on the body instantaneously. It proposes a life-saving device that the cushioning body formed by inflating the inflating cloth by pulling it arbitrarily is sufficiently wrapped to protect the human body. However, such life-saving equipment is also difficult to carry out in practice, in which the general public, who has not undergone systematic and repetitive training, suppresses fear and draws a string of action in an emergency. In addition, it is difficult to ensure that a simple airbag can sufficiently protect the evacuator's body when falling from a tall building.

SUMMARY OF THE INVENTION The present invention has been made to solve such a problem, and to provide a rescue device that can sufficiently protect the evacuator's body during evacuation due to falling from a height, and the operation method is simple and the evacuator can easily use it. It is a technical problem.

The rescue airbag device of the present invention for achieving the above technical problem is a control unit for supplying the first and second ignition signals activated at different time points, and a flexible support that can at least partially cover both shoulders and legs And at least one first airbag installed on the flexible support and inflating in response to the first ignition signal, and at least one second airbag installed on the flexible support and inflating in accordance with the second ignition signal. do.

In a preferred embodiment, the rescue airbag device further comprises a switch for activating the control unit.

Preferably, the rescue airbag apparatus further comprises a storage unit for storing the guide sound data for informing the inflation time of the first and second airbags, and a speaker for outputting the guide sound corresponding to the guide sound data.

Preferably, the first airbag and the second airbag are different from each other.

In a preferred embodiment, the control unit may further supply a third ignition signal different from the first and second ignition signal and the activation time point, the rescue airbag device is installed on the flexible support and the third ignition signal It may further comprise one or more third airbags inflating according to. In such a case, it is preferable that the protective portion of the third airbag overlaps at least partially with the protective portion of the first airbag or the second airbag.

According to the present invention, the evacuator can easily operate the device in two to three steps according to the guidance voice during evacuation due to the fall from the height, so that the device can overcome the fear and operate the device even under extreme tension. And, there is an advantage that can minimize the damage caused by malfunction. In particular, since a large number of airbags are inflated in stages, the evacuator can attempt to drop in an uneasy state of whether the airbag is operating.

Even at the moment of landing on the ground, the stepped airbags exhibit a cushioning effect in two or more layers, so that even if some of them are blown, the body of the evacuator is prevented by the buffering action of other airbags in or near the popped airbag. There is an effect that can be sufficiently protected. In particular, since the main body part of the evacuator is double-buffered by the air bag, it is possible to prevent the main body part from being damaged and at least to prevent death.

Such rescue airbag device of the present invention can be applied not only when evacuating from a high-rise building, but also in all situations where evacuation by dropping is required, such as in a sinking ship or a crashing aircraft. In particular, in the event of an accident on the ship, not only is it possible to escape quickly and safely, but it is also possible to protect the body temperature of the evacuator to prevent an emergency due to hypothermia, and the airbag acts as a buoy, making it easy for rescue ships and aircraft. There is an additional advantage that can be discovered.

On the other hand, the rescue airbag device according to the present invention can be manufactured and supplied at low cost because it is not structurally complex, it can be economically purchased and used by buyers, such as building owners.
