外部の吸気フィルタ付き内マスクからなる、特に災害時
用のフード付ガスマスクに関する。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a gas hood with a hood, especially for use in disaster situations, which comprises a head hood having a window and an adjustable band, and an inner mask with an intake filter placed under the head hood and outside the head hood. Regarding masks.

災害時用フード付ガスマスクの場合には、頚部における
フードの密封は弾性繊維材からなる一種のニットバンド
により行われる。In addition, smoke poisoning and obscuring visibility due to irritating thick smoke often prevent evacuation to the outdoors. In order to enable people in danger to self-help, gas masks with hoods are known which, on the one hand, filter the inhaled air to remove toxic combustion gases and, on the other hand, protect the eyes and head. . In the case of known disaster gas masks with hoods, the sealing of the hood at the neck is achieved by a type of knitted band made of elastic fiber material.

と密着するのが保証されるように構成することてある。When putting on the hood, it must be expanded and placed over the head. On the one hand, this makes it difficult to put on the hood in a panic state, and on the other hand, it gives the user a feeling of pressure. This is because when the hood is on, the knit band is placed around the neck area and creates a seal. In the case of known gas masks, the inner mask is pressed against the user's face from the outside by a band of the hood which is attached to the filter from the outside. As a result, the inner mask may not fit snugly to the face, causing it to shift while being worn. Additionally, the gas mask window is mostly flat, which limits the field of view. The object of the present invention is to provide a gas mask with a hood for use in disaster situations that can be easily and quickly put on and that also ensures that the hood fits very snugly to the wearer's significantly different head and face shapes. There are things to configure.
その上、使用者の視野も公知構造のガスマスクフードの

弁１０及びバンド６から構成される。Embodiments of the present invention will be described in detail below with reference to the drawings. As is clear from FIGS. 1 and 2, the hooded gas mask for disaster prevention according to the invention essentially consists of a vinyl chloride-coated viscose with a window 2 made of, for example, transparent foil or Plexiglas in the viewing area. Thickness 0.6Tr0! A flame-retardant or heat-resistant head hood 1 of L, a half-mask 3 as an inner mask with an intake filter 4 fixed to the inner mask 3 and head hood 1 by means of a tightening ring 5, an intake valve 10 and a band 6. configured.

及び第４図）。The band 6 is composed of a tightening band 6a and an endless band 6b that goes around the back of the head hood,
The same endless band 6b is firmly connected to the hood on the one hand at position X at the nape of the head and passes through the strap 12 at position y at the whorl of the head on the other hand (FIG. 1). This configuration provides the advantage of expanding and the possibility of length correction, without allowing the hood to slide off the head. The inner mask 3 has holding flaps 3a extending from the inner mask to the sides at approximately the height of the nasal wings in order to fix the buckles 7 of the tightening band 6a surrounding the head hood 1 from the outside. is formed (Figures 2 and 4).

）。The tightening bands are fixed to the head hood 1 using buckles 7, respectively. This is done by means of a buckle 7, which in a fixed position is firmly connected from the outside, including the hood material, to the retaining flap 3a of the inner mask 3 by screwing or riveting 8 (FIGS. 1 and 4). The presence of the attachment point of the tightening band on the hood at the rear, i.e. on the retaining flap 3a of the inner mask arranged inside the hood, ensures a secure and smooth attachment of the inner mask to the user's face. A stable fit is achieved. Furthermore, the window 2 sewn to the head hood 1 has a curved shape when the head hood is worn, based on the attachment position of the tightening band and the cutting of the head hood 1.
A regular curved frame is not necessary. The inner mask 3 has a nose base part 3b that is placed on the user's face as a seal for the breathing passage when the mask is worn (FIGS. 1a and 5).

せず）。One seal 9 is arranged on each side of the head hood 1 between the inner surface of the head hood and the inner mask 3. This seals the eye area against the threads of the head hood which opens downwards and connects to the ambient air. The seal may be configured as a sealing lip formed on the mask body or as a rubber, foam or elastomer component glued, inserted or buttoned to the mask body (not shown).

る（第３図）。The sealing component can be secured to one or both of the inner mask and the inner surface of the hood. As is clear from FIGS. 4 and 5, the seal 9 is fixed on one side to the mask body 3 within the confines of the holding zip 3a. The seal 9 is constructed, for example, as a cushion made of foam, and is shaped so as to exert a sealing pressure on the inner surface of the head hood. In a further advantageous embodiment, the seal 9a projects from the mask body and extends through the cheeks to the temples (FIG. 3).

する。In that case, the seal is configured on one side to adapt to the shape of the cheek and on the other side to take into account and fill the gap between the inner mask body and the inner surface of the hood. The action of the seal is advantageously such that the seal is at least partially connected to the outer tightening band 6a.
, which is enhanced by exerting pressure on the seal during band tightening. In yet another embodiment, not shown, the seal extends through the user's cheek towards the eye, which means that the seal extends approximately along the inner edge of the head hood window. means.

FIG. 6 shows cutouts 1 for the window 2, cutouts for the inner mask 3 with the intake filter 4, and a U-shaped cut 1 for forming the front part of the head hood.
1, the U-shaped cut forms a point of intersection a extending downwards at the point where the horizontal line and the two vertical lines meet.

n, and the cutout hole for window part 2 is 208 ugly at the maximum point.
It has a length of 8' at the minimum point between the indentation and the bottom facing edge of the U-cut. When sewing the cut pieces together using this method, the front part of the head hood and the top of the head should be
Since the head hood is curved in the front area due to the shaped seam, the sewn-in window 2 is also curved, creating a panoramic effect.
