The present invention relates to an oxygen tank fixing device of a fire truck seat, and in detail, the oxygen tank, which is a personal equipment of a firefighter, is firmly mounted on the back of the seat so as not to flow, and when it is detached, the oxygen tank can be pushed out by a lever operation. By allowing the oxygen tank to be easily withdrawn, the firefighters can move out more quickly for lifesaving at the fire or accident site. In the meantime, the oxygen tank is seated on the shoulder and moved to an uncomfortable position. With the oxygen tank on your knees, you can hold it with your hands to get rid of the discomfort you felt while traveling to the site.You can move comfortably even when you are on the road.You can get off quickly and put it in the accident site. Faster by mounting on a fixed fixture It will have to be dispatched.

In general, when firefighters or 119 rescuers are dispatched to various accident sites such as fire or various disasters, they are quickly moved by fire trucks or wreckers. In order to save lives, people have boarded vehicles while wearing personal portable equipment, including oxygen tanks and oxygen masks.

On the other hand, when a firefighter is seated on a seat of a fire truck with an oxygen tank wrapped around his shoulders, a bulky oxygen tank is located between the firefighter's shoulder and the back of the seat. It was difficult to posture, and it was difficult to wear seat belts. When a fire truck that was driving at high speeds was in a sudden stop or a sharp curve, it was necessary to give strength to the center of the body. There was a lot of concern that one crew would be exposed to danger.

In order to solve this problem, the oxygen tank is placed on the seat and placed on the crew's lap. In this case, the heavy oxygen tank presses the lower body, causing pain, and the oxygen tank had to be held by hand to prevent it from falling. Therefore, there were problems that caused communication or other activities necessary during the operation, and when suspending the accident site, the suspenders and waist girdle had to be worn again. there was.
