- In particular, an air injector (50) that includes: a hose (51) having a first end inserted between two sheets of fabric through a side of the lower portion of the upper body part (31) of the overalls and connected to a side of the lower portion of the variable contact tube (40) and a second end extending outward; and a cap assembly (52) for opening/closing the second end of the hose (51) may be formed at the variable contact tube (40) formed in a side of the upper portion of the upper body part (31) of the overalls (30).
- The cap assembly (52) may include a supporting ring (52 a) fixed to a side of the outer circumference of the second end of the hose (51), a connecting line (52 b) extending outward from a side of the supporting ring (52 a), and a cap (52 c) rotatably coupled to a side of an end of the connecting line (52 b).
- As the hose (51) extends outward, the air injector (50) having this structure provides a structure that enables a wearer to more easily inject air.
- Further, since the hose (51) is coupled to the lower portion of the variable contact tube (40), it is possible to prevent the problem that air moving up in the variable contact tube (40) is discharged outside through the hose (51) when the wearer drowns, and it is also possible to easily inject air without influence by the pressure of the air in the variable contact tube (40).
- According to the present invention, there are provided not only a function of floating the body of a wearer over a water surface in a submersion accident, but also a function of maintaining the body temperature, such that it is possible to minimize the possibility of wearer's death for hypothermia.
- Further, the work suit does not greatly decrease activity of a wearer in normal times, thereby preventing the problem of reduction of work due to the work suit.
- While the present invention has been described with respect to the specific embodiments, it will be apparent to those skilled in the art that various changes and modifications may be made without departing from the spirit and scope of the invention as defined in the following claims.
