A self-contained breathing apparatus that is equipped with a self-contained breathing apparatus 100 that can be worn in the clothes, in a chemical protective suit that protects the entire body in cooperation with the foot β that covers the region from the calf to the toes. The airtight clothing A is conventionally used. The rear surface of the trunk 2 bulges backward to form a space for accommodating the high-pressure air container 100a of the self-contained breathing apparatus. The wearer of self-contained breathing apparatus interior type airtight clothing A is cut off from the external environment.
In the conventional self-contained breathing apparatus-type airtight clothing A, the rear surface 1a of the head 1 is positioned at the base of the neck as shown in FIG. 1 (b) in order to minimize the dead space in the clothing space when worn. And then the lower end of the rear surface 1a of the head 1 is connected to the rear surface of the body portion facing the high-pressure air container 100a through a curved surface that protrudes upward along the top of the high-pressure air container 100a. .

In the conventional self-contained breathing apparatus interior type airtight clothing A, when the wearer squats down and takes a forward leaning posture, the sag portion 1a ′ between the lower end of the rear surface 1a of the head 1 and the curved surface convex upward is provided. Does not move in the out-of-plane direction, and there is a problem that the head rear surface 1a and the high-pressure air container housing lower surface 1a "are stretched and feel uncomfortable. The uncomfortable feeling uses the high-pressure air container 100a having a large volume. In addition, there was also a problem that the high-pressure air container 100a was caught by the stagnation portion 1a ′ when taking off the airtight clothing A.
The present invention does not feel uncomfortable when the wearer squats down and takes a forward leaning posture, and the high pressure air container does not get caught in the airtight clothes when taking off the airtight clothes. The purpose is to provide a self-contained breathing apparatus interior type airtight clothing that is comfortable to use.

In order to solve the above problems, in the present invention, a head that covers a part from the top of the human body to the neck, a torso that covers a part from the chest to the abdomen, and an arm that covers a part from the shoulder to the wrist, The legs that cover the part from the abdomen to the calf are integrally formed, and the entire body is protected in cooperation with the glove that covers the part from the wrist to the fingertips and the leg that covers the part from the calf to the toes. In a self-contained breathing apparatus with a self-contained breathing apparatus that can be fitted with a self-contained breathing apparatus, the head faces the back of the torso facing the high-pressure air container of the self-contained respirating apparatus. Provided is a self-contained breathing apparatus interior type airtight clothing characterized in that the rear surface of the section extends obliquely downward.
In the self-contained breathing apparatus interior-type airtight clothing according to the present invention, the rear face of the head is extended obliquely downward toward the rear face of the trunk facing the high-pressure air container of the self-contained breathing apparatus that is installed. The gap between the lower end of the rear surface of the head and the curved surface that protrudes upward that causes the rear surface of the head and the lower surface of the high-pressure air container housing part to stretch, and also causes the high-pressure air container to be caught when taking off the airtight clothing. Therefore, when the wearer squats and leans forward, the rear face of the head and the lower surface of the high-pressure air container housing part do not feel strange, and the high-pressure air container does not get caught in the air-tight clothes when taking off the air-tight clothes. The self-contained breathing apparatus interior type airtight clothing according to the present invention is more comfortable to use than the conventional one.

In a preferred embodiment of the present invention, the upper end is fixed to the upper surface of the head, and the opposite ends are fixed to both sides of the head. A vertical partial partition that divides into a rear portion located above the high-pressure air container is disposed in the head.
By disposing the vertical partial partition wall in the head, it is possible to prevent deformation due to lateral expansion of the head and deformation due to forward tilt of the head.
In a preferred embodiment of the present invention, a horizontal partition is disposed in the head, the front end being fixed to the lower end of the vertical partial partition and the rear end being fixed to the lower end of the rear surface of the head that is inclined.
When the horizontal partition is disposed in the head, the high pressure is placed in the bag-shaped portion formed by the inclined head rear surface, both sides of the head, and the vertical partial partition when a large-sized high-pressure air container is mounted. Occurrence of a situation in which the air container enters and interferes with the exhaust valve disposed on the inclined rear face of the head is prevented.
Since both sides of the horizontal bulkhead are free, insert a hand into the space surrounded by the vertical partial bulkhead, the horizontal bulkhead, the back of the head, and both sides of the head from the gap between the side edge of the horizontal bulkhead and the side of the head. Thus, maintenance of the exhaust valve disposed on the rear surface of the head can be performed.

A self-contained breathing apparatus interior type airtight clothing according to an embodiment of the present invention will be described.
As shown in FIG. 2, the self-contained respiratory-equipped airtight clothing B is similar to the self-contained respiratory-equipped airtight clothing A, with the head 11 covering the region from the top of the human body to the neck and the chest to the abdomen. The torso 12 covering the part extending from the shoulder, the arm covering the part extending from the shoulder to the wrist, and the leg covering the part extending from the abdomen to the calf are integrally formed, and the rear surface of the torso 12 bulges backward and is self-contained It has the structure which forms the space which accommodates the high pressure air container 100a of the respirator 100.
The rear surface 11a of the head 11 extends obliquely downward toward the rear surface of the trunk portion 12 facing the high-pressure air container 100a, and is connected to the upper end portion of the rear surface of the trunk portion.
The upper end is fixed to the rear end of the upper surface of the head 11 and the both ends are fixed to both side surfaces of the head 11. A vertical partial partition wall 11 b that divides into a rear portion located above is disposed in the head portion 11.
A horizontal partition wall 11c having a front end fixed to the lower end portion of the vertical partial partition wall 11b and a rear end inclined to the lower end portion of the head rear surface 11a is disposed in the head portion 11.
It is desirable that the vertical partition walls 11b and the horizontal partition walls 11c are made of a cloth material made of polyester or nylon and stretchable in both the vertical and horizontal directions. Further, it may be formed of the same flexible membrane material as that of the self-contained breathing apparatus interior type airtight clothing B.

In the self-contained breathing apparatus interior type airtight clothing B, the head rear surface 11a extends obliquely downward toward the rear surface of the trunk 12 facing the mounted high-pressure air container 100a, thereby providing a conventional self-contained breathing apparatus interior. In the airtight clothing A, the rear surface 1a of the head and the lower surface 1a ″ of the high-pressure air container housing portion are stretched, and the high-pressure air container 100a is caught when the airtight clothing A is taken off. Since the bend portion 1a 'between the convex surface and the convex surface is eliminated, there is no sense of incongruity that the head rear surface 11a and the high pressure air container housing lower surface 11a "are stretched when the wearer squats down and takes a forward leaning posture. In addition, the high-pressure air container 100a is not caught on the airtight clothing B when the airtight clothing B is taken off. Therefore, the self-contained breathing apparatus interior type airtight clothing B is more comfortable than the self-contained breathing apparatus interior type airtight clothing A.
Relative movement in the direction in which both sides of the head 11 are separated from each other is blocked by the vertical partial partition wall 11b, thereby preventing the head 11 from spreading in the lateral direction when using airtight clothing. The forward movement of the vertical partition wall 11b is blocked by the user's head, so that the head 11 is prevented from tilting forward when using the airtight clothing. By preventing the head 11 from spreading in the lateral direction and the forward tilt, the shape of the head 11 is prevented from being deformed when the airtight clothing is used.
When the large-sized high-pressure air container 100a is mounted, the horizontal partition wall 11c abuts on the top of the high-pressure air container 100a and is formed by the vertical partial partition wall 11b, the inclined head rear surface 11a, and both side surfaces of the head 11. The high-pressure air container 100a is prevented from entering the bag-like portion. By preventing the high-pressure air container 100a from entering the bag-like portion, the high-pressure air container 100a interferes with the exhaust valve 15 disposed on the inclined head rear surface 11a, and the exhaust valve 15 is damaged. The occurrence of the situation is prevented.
Since both side ends of the horizontal partition wall 11c are free, the vertical partition wall 11b, the horizontal partition wall 11c, the head rear surface 11a, and both side surfaces of the head 11 are surrounded by a gap between the side end of the horizontal partition wall 11c and the side surface of the head 11. The exhaust valve 15 disposed on the head rear surface 11a can be maintained by inserting a hand into the space.

The present invention can be widely used for self-contained breathing apparatus interior type airtight clothing.
