Although not shown, the inner garment of the pants 50 has substantially the same form as the outer garment 51 formed by sewing two front bodies and two rear bodies. The cloth is, like the upper garment inner garment 12, a grid-like inner cloth made of a heat-resistant and flame-retardant fiber cloth and two core cloths made of a heat-resistant, flame-retardant, flame-resistant fiber woven or non-woven cloth. Stitched with a thread, superimposed on the laminate with an outer cloth made of a laminate of a moisture-permeable waterproof sheet and a flame-retardant fiber or a flame-retardant woven fabric, and stitched at the periphery, and
It is made of a core cloth located on the outer cloth side with irregularities formed. Assembling to the outer garment 51 is performed by arranging the part covering the waist and the part covering the feet of the firefighter on these parts of the outer garment 51,
It is arranged by being arranged inside the outer garment 51 and being connected by fasteners such as zip fasteners and snaps.

When entering a fire fighting activity, the firefighter puts on his pants 50, wears firefighting shoes, puts on his upper coat 10, puts on a helmet, puts on gloves, and goes out with an air breather on his back. The trousers are worn, for example, by putting on the trousers 50 through the feet inside the inner garment 12, then hanging the suspender 61 on the shoulder, and closing the zip fastener at the front. The upper garment 10 is worn by putting the upper garment 10 through a hand inside the inner garment 12, passing the band through a band ring 37, and raising the collar 15 as necessary. The collar stand is formed by expanding the band 25 so as to straddle the open side of the collar 15, connecting the ends with the hook-and-loop fasteners 26 and 27, and closing the zip fastener 14.

When worn, the main body 13 of the upper garment 10 goes up from the waist of the firefighter body, the collar 15 goes around the neck,
7 covers up to the wrist, and pants 50 cover from waist down. At this time, the first portion 21 of the elastic portion connecting the sleeve 17 and the upper body 13 is located beside the firefighter, and the second portion 22 is located between the side and the vicinity of the base of the neck. Because the parts 21 and 22 are made of knit, even if a firefighter raises and lowers his arm to wear a helmet and carry an air breathing apparatus, the first part 21 expands and contracts, and the sleeve 17
Do not pull. Therefore, the firefighter can move his arm smoothly.

Thereafter, when a firefighter raises his arm up and down while holding a heavy fire hose or the like and extinguishing fire, the first part 21 expands and contracts. Section 22 expands and contracts together with the first section 21, and when the arm is moved back and forth, the second section 22 expands and contracts and does not pull the sleeve 17, so that the firefighter can extend the arm without burden. It can move smoothly and fire extinguishing work can be done promptly. Further, in this fire protection suit, when the arm is moved up and down, the third part 23 expands and contracts together with the first part 21 and the second part 22, and the shoulder pad 16 Even when the arm is moved back and forth without moving with the sleeve 17 due to expansion and contraction, the third part 23 expands and contracts together with the first part 21 and the second part 22, so that these movements can be improved. It can be done smoothly. The shoulder pad 16 bends back and forth along the thread 29 when these arms are moved up and down and back and forth, and does not hinder the movement of the shoulder.

Further, when a firefighter bends the elbow in wearing a helmet, an air breathing apparatus, or the like and extinguishing a fire, the back forming portion 31 of the sleeve 17 has an elongated shape extending in the longitudinal direction of the sleeve 17, and the elbow moves. Firefighters can easily do this because they follow and bend easily. At this time, since the elbow pad 18 bends from the thread 35 to make it easier to bend the elbow, the fireman
Together with the shearing of the shoulder pads 1 to 23 and the shoulder pad 16, the entire hand can be moved more easily.

Furthermore, in this fire protection suit, when a firefighter bends his waist during a fire fighting activity, his pants 50
The expansion and contraction portion 56 easily expands and contracts following the movement of the waist, so that this operation can be performed without burden. That is, when the trousers are worn, the elastic part 56 is located near the lower waist of the firefighter, and the elastic part itself is made of knit. Therefore, when the waist is bent and the pants 50 are pulled, the elastic part 56 extends,
The pants 50 are not pulled, and the waist can be bent smoothly. Since the knee pad 57 also bends from the thread 59,
Combined with the fact that the waist can be smoothly bent by the elastic portion 56, squatting can be easily performed.

The stretchable portions 21 to 23 and the stretchable portion 56 reliably protect the firefighter from flames, hot air, and the like despite expansion and contraction, since the fibers themselves are made of PBO fiber knit. be able to.

Further, the inner garment 12 is, as described above,
Even if the core cloth 46 has irregularities, and the irregularities form the heat insulating air layer 48 inside the outer garment 11 and the number of the inner garments 12 is reduced, the firefighter and the outer garment 11 can be reliably protected from fire and hot air. As a result, the entire upper garment becomes thinner and easier to wear, as well as lighter in weight, reducing the burden on firefighters in fire fighting operations.

Furthermore, even if the collar 15 is erected to protect the neck and the face, the collar 15 is not bent because the quilt 15 is quilted, and the upright state is maintained. Can be protected.

In the above-described embodiment, the upper garment 10 and the trousers 50 constitute one fire protection garment. However, the upper garment covers the lower body of the firefighter body and does not include trousers. It may be constituted as. Furthermore, the pants 50 are separated from the fire shoes,
While connecting the hem of the trousers outer garment 51 and the firefighting shoes with fasteners, insert the hem of the trousers inner garment inside the firefighting shoes,
In this state, it is hung by a hanging ring 62 on a hook or the like on a wall, and at the time of dispatch, the pants 50 can be worn and fire shoes can be worn at the same time, so that the dispatch can be performed more quickly. You may.
