Definitions
- the invention relates to protective equipment respirator comprising a respiratory mask, a harness allowing rapid installation, and sometimes glasses smoke protection integrated or not in the mask.
- the mask is fitted with a demand regulator, with dilution in general ; the masks can be provided to be put on overpressure (which requires that the harness can exert enough traction on the mask to apply it so noticeably waterproof on the face, despite the overpressure) or not.
- the present invention aims to provide equipment for respiratory protection, in particular against hypoxia, of the type above defined, likely to be implemented on a helmet and allowing extended wear without sacrifice for security.
- the invention provides a characterized equipment in that the harness also has a strap additional flexible, little or not extensible, provided with a manual direct clamping. We can consider as little stretch a fastener whose length does not vary from more than a few percent depending on its tension.
- the additional tightening strap can be made by a simple strap or strap in two connected parts by a clip already in place, which can be tightened by simple manual pull on a protruding strand.
- the additional strap is advantageously connected to the strap or to the extendable straps by inflation, so as to follow their movement.
- the additional strap can be placed between the two inflatable straps and connected to them by cords distributed around the head.
- a chin rest can be planned, adjustable or not.
- An upper strap passing over of the helmet, avoiding the downward displacement of the mask, for example in case of ejection, can be provided and equipped or not with means for adjusting the tightening.
- the mask can be simply oro-nasal, generally with a shape such as glasses or a visor can lean on it to protect the eyes.
- the mask can as well be complemented by one piece glasses with the face cover.
- the mask shown has an oro-nasal face cover attached to a regulator at the request 13 and to a rigid connection block 12.
- the block of connection is provided with a connection fitting with a pipe flexible 14 intended to be connected to a gas source pressurized breathing (pressurized oxygen in general).
- the harness shown by way of example comprises two straps 16 each consisting of an inner tube in elastic material contained in an inextensible sheath limiting the elongation of the tube.
- the length at rest of internal tubes is such that they tend to apply the face cover on the face with the force necessary to ensure the required seal, even when the mask is subject to respiratory overpressure.
- the regulator will be with or without dilution by aspirated air in the cabin, with or without the possibility of overpressure.
- the regulator is connected to the pipe supply 14 by the connection block 12.
- This block carries means for manually controlling the inflation of the straps 16, constituted for example by a tap intended to be actuated by manual pinching of two ears 18 carried by the connection block 12 and one of which is tiltable.
- the tap is constructed so as to put in communication an internal volume of the connection block 12 and the 16 straps with the atmosphere when free. It allows then the straps to retract and apply the mask against the face.
- the tap When the tap is turned on, it admits unlike pressurized gas from the supply line 14 in the volume and causes a sufficient lengthening of the straps to allow quick place. So that the straps, when they retract, ensure good contact with the back of the head, they are advantageously connected by passers-by 20 who limit their spacing.
- the harness also includes at least one additional strap flexible, but not extensible or not very extensible 24, intended to be tightened on the helmet to apply more firmly the mask on the face.
- the strap 24 shown on Figure 1 is in three parts connected by two fasteners 26 placed one on each side of the head and that the wearer mask can be easily adjusted to tighten the strap additional. These fasteners can for example have the constitution shown schematically in Figure 2.
- the fastener then has an elongated metal plate 28 attached at the end of one of the parts of the additional strap 24.
- the terminal portion of the other party constitutes a sliding loop around the plate 28 and ends by a free strand 30 on which it suffices to pull to tighten the additional strap 24.
- this strap occupies a suitable location when tightening, it advantageously crosses the loops 20 which hold it between the two inflatable straps 16.
- the harness is supplemented by a chin strap 32, adjustable or not, avoiding the risk of the helmet going up towards the eyes.
- FIG. 3 where the bodies corresponding to those of FIG. 1 are designated by the same reference number
- glasses 32 of smoke protection fitted with a retaining element clean 34, can be attached to the helmet independently of the harness.
- the embodiment of Figure 4 includes, instead glasses, an eye screen 36 which is integrated into the mask, according to a provision comparable to that which is described in the (Design Patent) U.S. Des. 304,384.
- FIG. 5 is differentiates from the previous one in that it includes not only an additional lateral strap 24, but also a strap upper 38 provided, like strap 24, with a fastener 40 allowing to stretch it if necessary.
- the upper strap 38 ends by a hook 42 which can be fixed to the edge of the helmet.
- the top strap 38 should be extended during storage, so as not to interfere with quick place.
- This upper strap can also be installed transversely and be connected to the upper tube 16.
- Figure 6 shows a possible constitution of such clip 44, consisting of a simple metal wire clip (spring steel for example) intended to maintain a buckle on one of the inflatable straps 16.
- a simple metal wire clip spring steel for example
- the middle part can be fixed permanently.
- Fastener 44 can have many different shapes from that described as a simple example.
- the clip consists of a plate 46 and studs 48 around which at least one of the tubes harness can be put on to increase tension and tightening on the head.

Description
- la figure 1 est une vue en perspective montrant l'aspect extérieur d'un équipement de protection conforme à un premier mode de réalisation de l'invention ;
- la figure 2 montre une constitution possible d'une attache à serrage rapide pouvant être prévue sur la sangle additionnelle unique de l'équipement de la figure 1 ;
- les figures 3, 4 et 5, similaires à la figure 1, montrent des variantes de réalisation ;
- les figures 6 et 7 montrent des constitutions possibles d'un élément supplémentaire permettant de diminuer temporairement la longueur du harnais, en vue d'une mission n'exigeant pas le port de casque.
