Abstract

A life jacket is disclosed. According to the present invention, the life jacket comprises: a wearable part which is worn on an upper body of a user; an inflatable tube which is coupled to the wearable part and expands when air is injected; and an inflator for forcibly injecting air into the inflatable tube. According to the present invention, it is possible to provide a life jacket made to stably keep an upper body of a wearer, caught in a rip current, out of the water without interfering with the wearer's body movement in normal times, thereby stabilizing the panicked drowning person's psychological stability and preventing the occurrence of hypothermia.

Description

Life jacket {LIFE JACKET}

The present invention relates to a lifejacket, and more particularly, to a lifejacket made to support a part of the body above the water surface by buoyancy when a person falls into the water when worn.

A rip current is an ocean current in which waves rushing to the shore suddenly return to the distant sea. In addition, it is difficult to observe because it occurs locally depending on the frequently changing seafloor topography conditions and the shape of the coastline.

The biggest beach accident caused by rip currents that occurred abroad was an accident in 1955 when girls from a municipal junior high school were swept away by a rip current during a swimming class off the coast of Nakakawahara, Japan. Suddenly, a huge wave swept away the students one after another, killing 36 people and leaving only 9 survivors. In the case of falling into high-velocity and high-velocity water such as a rip current, the use of a life-saving device exerts an absolute influence on the survival of the drowning person.

Life saving apparatus means an apparatus that supports a drowning person on the water. The representative lifesaving devices are a lifejacket and a lifebuoy. Life jackets and lifebuoys can be seen installed not only in ships but also in ports and berthing facilities.

A life buoy is a buoyant, circular object thrown from a boat to rescue a drowning person. However, it is very difficult to deliver a lifebuoy to a drowning person in a situation where the flow velocity is high and the wave height is high.

A life jacket is a life jacket in the form of a vest that supports the head above the water surface by buoyancy when a person falls into the water. The life jacket allows only the head of a drowning person to float above the surface even in calm water.

Therefore, it is difficult for a person in distress who is swept away by a drift current to put their head on the surface of the water even if they are wearing a lifejacket. In addition, there is a problem that a drowning person wearing a lifejacket is easily susceptible to hypothermia because the area under the head is located in the water.
