    [0001] FIELD OF THE INVENTION The invention relates to a control assembly for respiratory mask of an aircraft crew member.
    [0002] Background of the invention In known manner, such a control assembly of this type comprises: a housing forming a support; a mode selection button mounted movably on the support between at least a first position and a second position; regulator adapted to be supplied by a source of breathing gas and adapted to supply a breathing gas breathing cavity in at least the two following operating modes: when the mode selection button is in said first position, the regulator supplies the cavity as long as the pressure in the respiratory cavity is not greater than a first pressure relative to the ambient pressure, - when the mode selection button is in the second position, the regulator supplies the respiratory cavity as long as the pressure in the respiratory cavity is not greater than a second relative pressure with respect to the ambian pressure te, the first pressure being greater than the second pressure. The different positions of the mode selection button correspond to different modes of operation of the regulator that should be adopted depending on the circumstances. The user, usually a pilot, co-pilot or flight engineer must manually select the operating mode appropriate to the circumstances. When the mode selection button is in the first position, the regulator provides the user, via the respiratory cavity, with respiratory gas (generally almost pure oxygen) undiluted and overpressurized with respect to the ambient air in the cabin of the plane. This position is best suited in critical situations. It is usually called "emergency" and allows in particular to avoid the user of the respirator to suffer the harmful effects of toxic fumes due for example to a fire in the cabin of the aircraft.
    [0003] There are generally other modes of operation of the regulator to reduce the fatigue of the user caused by the fact that the respiratory gas is supplied to him with a relatively high overpressure compared to the ambient air and / or to reduce the consumption of breathing gas. Although the known control assemblies provide satisfaction and provide good security, the invention aims to further improve the security they provide. SUMMARY OF THE INVENTION In order to overcome the aforementioned problems, according to the invention, the mode selection button comprises at least one projecting portion urging the user to place the mode selection button in the first position. It appeared that in the prior art, the user could detect the position in which is the mode selection button, especially because of a marking on the mode selection button. Therefore, in a first step the user determined the position in which the mode selection button was (for example by looking at the marking on the button or memory), in a second step the user was thinking to determine in which meaning move the mode select button and in a third step the user was moving. These three stages succeeding one another quickly, this procedure appeared satisfactory. However, it has appeared according to the invention that, in order to place the mode selection button more rapidly in the first position or to leave it there, the user did not necessarily need to know the position in which the button is located. mode selection. Thus, it has been found in particular that by providing the mode selection button with a protruding portion urging the user to move the mode selection button to the first position, preferably on the basis of tactile inductions, by example because of the shape and / or the position of the protruding portion, the user did not need to perform the two steps mentioned above. In case of a sudden emergency, the user therefore places the mode selector button in the first position faster, which improves security and the user does not need to see to position the mode selection button. in the first position. Of course, it is possible that in return the user takes a little longer to place the mode selection button in the second position, when necessary. However, a slight loss of time in such a situation does not have a significant impact on safety, especially in relation to the gain obtained during an emergency. According to another feature according to the invention, preferably, the mode selection button is rotatably mounted about an axis of rotation extending in one direction.
    [0004] In a complementary manner, according to the invention, the regulation assembly preferably has the following characteristics: the support has an adjacent zone offset with respect to the projecting portion in the direction of the axis of rotation and in the immediate vicinity of the mode selection button, - in the second position of the mode selection button, the projecting portion of the mode selection button protrudes from the adjacent area of the support, radially to the axis of rotation, and - when moving from the second position to the first position, the projecting portion of the mode select button is moved to said adjacent area of the support. Thus, the user is naturally encouraged to move the mode selector button to the first position rather than the second position. According to a complementary characteristic according to the invention, preferably the projecting portion of the mode selection button is flush with the adjacent area of the support in the first position.
    [0005] Thus, the user positioning his finger in the direction of the axis of rotation will detect the first position by the fact that his finger will be in contact with both the projecting portion of the mode selection button and the adjacent area of the support.
    [0006] According to a still complementary characteristic according to the invention, preferably, in the first position, the projecting portion of the mode selection button is substantially in the extension of the adjacent zone of the support over a length of at least 1 centimeter, perpendicularly to the axis of rotation.
    [0007] Thus, the first position will be particularly characteristic for the user. In a complementary manner, according to the invention, the regulation assembly preferably has the following characteristics: the mode selection button comprises a third position, the first position being situated between the second position and the third position; the mode selection button has a secondary projecting portion and the support has an adjacent secondary area offset from the secondary projecting portion in the direction of the axis of rotation and in the immediate vicinity of the mode selection button; third position of the mode selection button, the secondary projecting portion of the mode selection button protrudes from the secondary adjacent area of the support, radially to the axis of rotation, when moving from the third position to the first position position, the secondary projecting portion of the mode select button is moved to said area a secondary portion of the support, and - in the first position of the mode selection button, preferably the secondary projecting portion of the mode selection button is flush with the secondary adjacent area of the support.
    [0008] Thus, the user is encouraged to place the mode selection button in the first position, both from the second position and from the third position, although it is necessary to turn in two opposite directions depending on whether the button mode selection is in the second position or in the third position. According to an alternative characteristic according to the invention, preferably the mode selection button comprises a third position, the second position being situated between the third position and the first position. In a complementary manner, according to the invention, the regulation assembly preferably has the following characteristics: the mode selection button comprises a secondary projecting portion and the support has a secondary adjacent zone offset from the projecting portion; mode selection button in the direction of the rotation axis and in the immediate vicinity of the mode selection button, - in the third position of the mode selection button, the secondary projection of the mode selection button protruding from the secondary adjacent area of the support, radially to the axis of rotation, - when moving from the third position to the second position, the secondary projecting portion of the mode selection button is moved to said secondary adjacent area of the support, and - in the second position of the mode selection button, preferably the sail portion The secondary side of the mode select button is flush with the adjacent secondary area of the media. Thus, the user is naturally encouraged to move the mode selection button from the third position to the second and the second position to the first position, while preferably can easily locate the second position. In addition, according to the invention, the regulation assembly preferably has the following characteristics: the mode selection button comprises a pair of projecting portions comprising a first projecting portion and a second projecting portion, diametrically opposite with respect to the axis of rotation, and - the first projecting portion and the second projecting portion of the mode selection button respectively have a first bearing surface and a second bearing surface, each extending substantially radially to the axis of rotation. rotation and such that a force exerted on one or the other of the first bearing surface and the second bearing surface in the direction of the axis of rotation rotates the mode selection knob from the second position to the first position. Thus, pinching the mode select button between thumb and forefinger by respectively pressing the first bearing surface and the second bearing surface moves the mode select button to the first position. The user can thus very quickly and without error set the mode selection button in the first position. According to a complementary feature according to the invention, preferably the first bearing surface and the second bearing surface are each concave and preferably smooth. Thus, the movement of the mode selection button to the first position will be facilitated. It will be understood by smooth that the fingers of the user can easily slide on the bearing surface, at least perpendicular to the axis of rotation.
    [0009] BRIEF DESCRIPTION OF THE FIGURES Other features and advantages of the present invention will become apparent from the following detailed description, with reference to the accompanying drawings, in which: FIG. 1 illustrates in perspective a control assembly according to the invention, - FIG. 2A, FIG. 2B and FIG. 2C illustrate, according to the arrow marked II in Figure 1, the regulation assembly according to a first embodiment respectively in a first position, a second position and a third position, - FIG. 3A, FIG. 3B and FIG. 3C illustrate, according to the arrow marked III in FIG. 1, the regulation assembly according to a second embodiment respectively in the first position, the second position and the third position, FIG. 4A, FIG. 4B and FIG. 4C illustrate, according to the arrow marked IV in FIG. 1, the regulation assembly according to a third embodiment respectively in the first position, the second position and the third position. DETAILED DESCRIPTION OF THE INVENTION The figures illustrate a breathing mask 100 disposed in a pressurized cabin 8 of a commercial aircraft intended to transport crew members and generally also passengers. A device, preferably of the so-called isobar type, pressurises the cabin so that it does not exceed a pressurization pressure, generally corresponding to an altitude of between 1,500 meters and 2,400 meters. As the aircraft rises, the pressure in the cabin is substantially equal to the pressure outside the cabin, until said pressurization pressure is reached. Under normal conditions, the pressure in the cab is then kept constant until the external outside pressure becomes greater than the pressurization pressure. The purpose of the respirator is to provide the user with sufficient oxygen and to be protected from harmful substances in the event of incidents such as depressurization, the presence of toxic gases or the like, preventing the occupants of the cabin from breathing. normally. The respirator 100 includes a regulator assembly 1 and an oronasal face cover 2. The oronasal face cover is intended to be applied substantially tightly to a user's face around his nose and mouth. The oronasal face cover 2 has a breathing cavity 4 in which the user breathes. The regulating assembly 1 comprises a support 10, a mode selection button 20 and a regulator. In the illustrated embodiments, the support 10 is in the form of a housing in which the regulator is disposed. The carrier 10 has a breathing gas supply port 6 for receiving the end of a hose for connecting the regulator to a source of respiratory gas substantially containing oxygen. As is well known, the regulator comprises three modes of operation. In the first operating mode, called "emergency" mode, the regulator feeds the breathing cavity 4 only with respiratory gas until a slight excess pressure is reached in the breathing cavity 4 relative to the ambient pressure of the cabin air, this overpressure is generally between 3 mbar and 30 mbar. In the most common overpressure values, between 3 and 7 mbar, this overpressure value is hardly felt by the user. Beyond 10 to 12mbar, overpressure requires a substantial additional effort to the user to breathe which is quickly felt by the user. In the second mode of operation, referred to as "100%" mode, the regulator supplies the breathing cavity 4 only with respiratory gas until it reaches substantially the ambient pressure. In practice, it is generally useful to provide for stopping the supply of the respiratory cavity before the breathing cavity reaches the ambient pressure, so that there is a very slight depression (a few tenths of a mbar to a few mbar) in the Respiratory cavity 4 The third respiratory mode, called "normal", differs from the second respiratory mode in that the respiratory cavity 4 is supplied with respiratory gas diluted with air, generally ambient air, the proportion of which is usually In particular, the function of the pressure in the cabin 8. The mode selection button 20 has a first position shown in FIGS. 2A, 3A, 4A that commands the regulator to operate in the first mode. The mode selector button 20 has a second position shown in FIGS. 1, 2B, 3B, 4B commanding the regulator to operate in the second mode. The mode select button 20 has a third position shown in Figs. 2C, 3C, 4C commanding the controller to operate in the third mode. The mode selection button 20 is rotatably mounted around an axis of rotation Z. In the illustrated embodiment, the axis of rotation Z extends substantially vertically when the user holds his head vertically, so that that the mode selection button 20 extends under the support 10. Of course, the mode selection button 20 could be placed differently, especially on the front of the support 10 and / or with an axis of rotation extending substantially horizontally. Alternatively, the mode select button may translate instead of pivoting. In known manner, the three positions of the mode selection button are discrete positions materialized by notches. The mode selection button 20 has a bottom and a peripheral edge. Entries EMGCY, 100% and N are carried both on the bottom and at two laterally opposite locations on the peripheral edge of the mode select button 20 in the illustrated embodiments. Three markers, a mark lla on the bottom and two lateral marks 11b, 11c are optionally arranged on the support 10 to display the mode selection position 20 and therefore the operating mode of the selected regulator. In particular, the lateral marks 11b and 11c allow a person disposed next to the user to know the operating mode of the selected regulator. A cross check between pilot and co-pilot in particular is easy.
    [0010] The mode selection button 20 has a first projecting portion 22 and a second projecting portion 24 diametrically opposite to the axis of rotation Z. As illustrated in FIGS. 2B, 3B and 4B, in the second position 100% of the mode selection button 20, the first projecting portion 22 projects, radially to the axis of rotation Z, with respect to a first adjacent zone 12 of the support 10 which is offset relative to the first projecting portion 22 in the direction of the Z axis of rotation and in the immediate vicinity of the mode selection button 20. By pressing the first projecting portion 22, the mode selection button 20 is moved to the first position EMGCY, the first projecting portion 22 coming closer to the first adjacent zone 12, in a direction perpendicular to the axis of rotation Z.
    [0011] In the first EMGCY position of the mode selection button 20, illustrated in FIGS. 2A, 2B and 2C, the first projecting button portion 22 of the mode selection button is flush with the first adjacent zone 12 of the support 10. In particular, at least a portion of the first projecting portion 22 is in the extension of the first adjacent zone 12 of the support 10, so that the user will be able to touch with the same finger simultaneously the first projecting portion 22 of the mode selection button 20 and the first adjacent zone 12 of support 10, which will give him a tactile indication that he selected the first mode of the regulator.
    [0012] In the first embodiment, illustrated in FIGS. 2A, 2B and 2C, and in the second embodiment, illustrated in FIGS. 3A, 3B and 3C, the first projecting portion 22 has a first bearing surface 23 extending substantially radially to the axis of rotation Z and the second projecting portion 24 has a second bearing surface 25 extending substantially radially to the axis of rotation Z. The first bearing surface 23 and the second bearing surface 25 are intended to receive for one the thumb and the other preferably the index of the user. As illustrated in FIGS. 2B, 2C, 3B and 3C, a user pinching movement causes the application of forces F23, F25 directed towards each other respectively on the first bearing surface 23 and on the second bearing surface 25 of the mode selection knob which tends to rotate it towards the first position EMGCY, as illustrated by the arrows R. This movement is advantageously favored by the concave shape of the first bearing surface 23 and the second bearing surface 25, perpendicularly (that is in a plane perpendicular) to the direction of the axis of rotation Z. In addition, this movement is advantageously favored by the fact that the fingers of the user can slide on the first bearing surface 23 and the second bearing surface 25 respectively as the fingers of the user move closer together. For this purpose, perpendicularly (in other words in a plane perpendicular to the direction of the axis of rotation Z), the first bearing surface 24 and the second bearing surface 25 are smooth and / or have a low coefficient of friction. . However, it would be possible to provide striations extending radially in the direction of the axis of rotation Z or any other means preventing the fingers from sliding on the first bearing surface 24 and / or the second bearing surface 25 in the direction of the axis of rotation Z without jeopardizing the implementation of the present invention. On the other hand and without necessarily being related to what has been indicated in connection with the shape of the first bearing surface 23 and the second bearing surface 25, in the second position 100% of the button mode selection 20, the second projecting portion 24 of the mode selection button 20 is flush with a second adjacent zone 14 of the support 10 which is substantially in the extension of the second projecting portion 24, in the direction of the axis of rotation Z As shown in FIGS. 2C and 3C, in the third position N of the mode selection button 20, the first projecting portion 22 and the second projecting portion 24 project relative to the first adjacent area 12 and the second adjacent area 14 respectively, radially to the axis of rotation Z. When the user presses the first projecting portion 22 and / or the second projecting portion 24, preferably on the first bearing surface 23 and the second With the pinching surface as described above, the forces F23, F25 applied to the mode select button 20 rotate the mode select knob 20 to the first position EMGCY, as illustrated by the arrows R. In the second embodiment and in the third embodiment, the second position 100% being located between the third position N and the first position EMGCY, during the movement of the mode selection button 20 from the third position N towards the first position. EMGCY position, the first projecting portion 22, in particular the first bearing surface 23, is moved to the first adjacent area 12 and the second projecting portion 24, in particular the second bearing surface 25, is moved to the second area adjacent 14. As previously indicated, in the second position 100% of the mode selection button 20, the second projecting portion 24, in particular the second surf a support 25, flush with the second adjacent zone 14, the user will touch with the same finger simultaneously the second projecting portion 24 of the mode selection button 20 and the second adjacent zone 14 of the support 10, which will give him an indication touch that he selected the second mode of the regulator. It can then continue the rotational movement of the mode selection button 20 to the first position EMGCY, as described above, or interrupt it according to its desire, from only tactile indications. As illustrated in particular in FIGS. 2A and 3A, the second embodiment differs from the first embodiment in that in the first EMGCY position of the mode select button 20, the mode select button 20 does not show any projecting portion, radially to the axis of rotation Z relative to an adjacent region of the support which would be in the immediate vicinity and offset in the direction of the axis of rotation Z. The first position EMGCY of the mode selection button 20 is therefore particularly characteristic for the user. In the third embodiment, as illustrated in FIG. 4B, in the second position 100% of the mode selection button 20, the second projecting portion 24 protrudes, radially from the axis of rotation Z, with respect to FIG. a second adjacent zone 14 of the support 10 which is offset with respect to the second projecting portion 24 in the direction of the axis of rotation Z and in the immediate vicinity of the mode selection button 20. When the mode selection button is in the second position 100% and that the user presses the first projecting portion 22 and / or the second projecting portion 24 to rotate the mode selection button 20, the second position 100% being an extreme position, the user can not turn the mode selector knob 20 only in one direction (clockwise in FIG. 4B) to the first position EMGCY. When the mode selection knob 20 is moved from the second position 100% to the first position EMGCY, the first projecting portion 22 is moved to the first adjacent area 12 and the second projecting portion 24 is moved to the second adjacent area 14.
    [0013] In the first position EMGCY, as illustrated in FIG. 4A, the first projecting portion 22 is flush with the first adjacent zone 12 in the direction of the axis of rotation Z and the first projecting portion 22 is in the extension of the first zone adjacent 12 in the direction of the axis of rotation Z, over a length L of at least 1 cm, preferably at least 2 cm perpendicular to the direction of the axis of rotation Z. Similarly, the second projecting portion 24 is flush with the second adjacent zone 14 in the direction of the axis of rotation Z and the second projecting portion 24 is in the extension of the second adjacent zone 14 in the direction of the axis of rotation Z. Similarly, such as illustrated in FIG. 4C, according to the third embodiment, in the third position N of the mode selection button 20, a first secondary projecting portion 26 protrudes, radially from the axis of rotation Z, relative to a first adjacent secondary area 16 of the support 10 which is offset relative to the first secondary projecting portion 26 in the direction of the axis of rotation Z and in the immediate vicinity of the mode selection button 20. In addition, a second secondary projecting portion 28 , substantially diametrically opposed to the first secondary projecting portion 26, protrudes radially from the axis of rotation Z relative to a second adjacent secondary zone 18 of the support 10 which is offset relative to the second secondary projecting portion 28 in the direction of the Z axis of rotation and in the immediate vicinity of the mode selection button 20. When the mode selection button is in the third position N and the user presses the first secondary portion 26 and / or second secondary projecting portion 28 for rotating the mode selection knob 20, the third position N being an extreme position, the The user can only rotate the mode selector knob 20 in one direction (counterclockwise in FIG. 4C) to the first position EMGCY.
    [0014] In the third embodiment, the third position N is opposite to the second position 100%. The first position EMGCY is located between the second position 100% and the third position N. When moving the mode selection button 20 from the third position N to the first position EMGCY, the first secondary projecting portion 26 is moved to the first position secondary adjacent area 16 and the second secondary projecting portion 28 is moved to the second secondary adjacent area 18. In the first position EMGCY, as shown in FIG. 4A, the first secondary projecting portion 26 is flush with the first adjacent secondary area 16 following the direction of the axis of rotation Z and the first secondary projecting portion 26 is in the extension of the first adjacent secondary zone 16 in the direction of the axis of rotation Z, over a length L of at least 1 cm, of preferably at least 2 cm perpendicular to the direction of the axis of rotation Z. Similarly, the second secondary projecting portion 28 is flush with the a second secondary adjacent zone 18 in the direction of the axis of rotation Z and the second secondary projecting portion 28 is in the extension of the second secondary adjacent zone 18 in the direction of the axis of rotation Z.
    [0015] Naturally, the invention is not limited to the embodiment (s) described for illustrative, non-limiting. Thus, except where it is apparent from the description, it would be possible to modify each of the 3 embodiments to give it all or part of the characteristics of one or other of the other embodiments.
    [0016] In addition, in connection with being mobile in rotation, the mode selection button could in particular be mobile in translation.
