    [0001] BACKGROUND OF THE INVENTION The invention relates to the field of instrumented clothing, in particular sports clothing or for the medical monitoring of a patient. These clothes are mostly elastic and equipped with sensors. Such sensors are generally associated with a textile so as to make it possible to measure the physiological and / or actimetric characteristics of the wearer of the garment.
    [0002] The invention is therefore more particularly the so-called "intelligent" clothing connected to each other and / or to an additional computer component allowing, for example, to display a graphic representation that is a function of the measurement made by the sensor. Furthermore, the sensors used for this type of application can be in various forms and in particular: the sensors for measuring cardiac frequency and variability (ECG electrodes), the respiratory rate, the skin temperature, the heat flow, the fluid flow, blood oxygenation, muscle oxygenation, chemical composition of sweat, bio-impedance, position, speed or acceleration of all or part of the body of the wearer of the garment.
    [0003] PRIOR ART In general, the instrumented garments in which sensors are arranged have conductive electrical wires which can be woven directly with the warp and weft threads inside the fabric. Such an embodiment is described in particular in document WO 2005/032447 in which conductive elastic threads can simply be woven with non-conductive elastic threads. However, in this case, these conductive elastic son are then visible at the level of at least one face of the textile and can therefore be damaged, especially when the user wears the garment or when he is machine washed.
    [0004] It is also known, and as described in EP 2 505 090, elastic instrumented clothing in which an elastic conductive thread is positioned on the surface of the textile, then is covered with an adhesive protective film. protection increases the rigidity of the instrumented garment which loses the intrinsic characteristics of flexibility inherent to a textile. This results in discomfort for the wearer of such a type of clothing. In addition, the adhesive material may degrade over time, in particular because of the mechanical wear associated with the use of clothing and / or washing in successive machines.
    [0005] A first objective is to provide effective protection of an elastic conductive wire against external mechanical attack, and in particular those caused by friction and / or washing machine.
    [0006] Another object of the invention is to retain the flexibility and elasticity of the textile equipped with such an elastic conductive thread. SUMMARY OF THE INVENTION The invention thus relates to an instrumented garment comprising an elastic woven fabric comprising: non-conductive elastic yarns arranged in both warp and weft directions, and; at least one resilient conductive wire for forming a bus for transmitting at least one electrical signal from a sensor responsive to a physiological and / or actimetric characteristic of the wearer of the garment, the at least one elastic conductive thread being positioned only in the textile weft direction; According to the invention, such a garment is characterized in that the elastic conductive wire is arranged in a protective sheath, such a sheath being formed by selective weaving of the non-conductive elastic yarns arranged in the warp direction to form two parallel textile webs superimposed and locally disjointed.
    [0007] In other words, the elastic conductor son or son are invisible and protected by the envelope that forms the two parallel textile webs. To produce such a sheath, the non-conductive elastic warp yarns are divided into two plies and alternatively worked in two weaves arranged in parallel.
    [0008] To produce the upper ply, only the warp yarns of the first textile ply are made to work, that is to say that in this first group of threads the warp yarns regularly separate between the high position and the position. bass, then at each change, a weft thread is introduced. The set of warp threads of the lower sheet remain in their lower position. Similarly, to make the lower ply, only the warp threads of the second textile ply are made to work, that is to say that in this second group of threads the warp threads regularly separate between the high position. and the low position, then at each change, a weft thread is introduced. All the warp son of the upper web remain in their up position. During the formation of the sheath, one or more elastic conductive threads are introduced in the weft which will be positioned between the two parallel plies. For this, all the warp threads of the upper ply are placed in the upper position while all the threads of the lower ply are placed in the lower position. The elastic conductive wire is free to move inside a sheath which allows a great flexibility to the textile and equipped.
    [0009] The sheath is finalized as described above, then it is closed again by making the warp threads of the two plies work together. Advantageously, the elastic conductive yarn may be bonded with non-conductive binding yarns at least at the edges of the woven fabric, the binding yarns 30 making it possible to keep the elastic conductive yarn taut. Thus, the elastic conductive wire is held in tension inside the sheath, which facilitates subsequent operations, in particular connection with a sensor.
    [0010] In practice, the non-conductive elastic son forming the sleeve may have a coefficient of elongation before rupture less than that of the elastic conductive wire. In other words, the non-conductive elastic wires forming the protective sheath are less elastic than the elastic conductive wire. Such an arrangement also makes it possible to confer additional protection on the elastic conductive thread with respect to certain tensile stresses. In this case, the difference between the elongation coefficient before rupture of the elastic conductive yarn and the elongation coefficient before breaking of the non-conductive elastic yarns is between 5 and 50%. Preferably, this difference can also be between 10 and 30%. By way of example, the non-conductive elastic yarns may have an elongation coefficient before breaking of about 150% while the elastic conductive yarn may have an elongation coefficient before breaking of about 190%. According to a particular embodiment, the sheath may be discontinuous, allowing the elastic conductive yarn to appear locally on at least one outer surface of the instrumented garment, this discontinuity of the sheath forming a connection zone for the elastic conductive yarn. In other words, such a connection zone allows the elastic conductive thread to appear punctually on the surface of the textile and makes it possible to make an electrical connection between the elastic conductive wire and an auxiliary element such as a sensor. The visible length of this elastic conductive wire may advantageously be in the range of 1 to 20 mm. In this way, the elastic conductive wire may have a sufficient free length 30 for welding or bonding with the auxiliary member. Advantageously, the garment may comprise at least one sensor sensitive to a physiological and / or actimetric characteristic of the wearer of the garment, such a sensor being connected to the elastic conductive yarn at the level of the connection zone. Thus, the sensor comprises at least one connecting lug intended to be secured to the elastic conductive wire at the connection zone. Once secured to each other, the connection is then covered by a waterproof membrane which may in particular be formed by a silicone-based material. Brief Description of the Figures The manner of carrying out the invention, as well as the advantages which result therefrom, will emerge from the description of the embodiment which follows, given as an indication and without being limiting, in support of the figures in which: Figure 1 is a schematic front view of an instrumented garment according to the invention. Figure 2 is a schematic cross-sectional view of the elastic textile according to the invention. Figures 3 and 4 are schematic front views showing details of different areas of a woven fabric according to the invention. DESCRIPTION OF THE INVENTION As already mentioned, the invention relates to an instrumented garment comprising an elastic woven fabric. As shown in Figure 1, the garment 1 comprises an elastic woven fabric 2 allowing a user to practice including a sport or any physical activity. Such a garment 1 thus comprises a sensor 5, sensitive to a physiological and / or actimetric characteristic of the wearer of the garment. In addition, such a sensor 5 is electrically connected with conductive wires forming a connection bus for transmitting different electrical signals between the sensor 5 and a processing unit not shown. The sensor 5 is advantageously chosen from the group comprising the sensors making it possible to measure the frequency and the cardiac variability (ECG electrodes), the respiratory rate, the skin temperature, the heat flow, the water flow, the oxygenation of the blood, the oxygenation muscle, chemical composition of sweat, bio-impedance, position, speed or acceleration of all or part of the body of the wearer of the garment. Such a garment 1 is thus formed by the weaving of non-conductive elastic yarn 5 arranged both in the warp and weft directions, and making it possible to produce at least one protective sheath 6 inside which an elastic conductive thread may be positioned. . Indeed, as shown in FIG. 2, non-conductive elastic wires 3 arranged both in warp and weft make it possible to define two parallel and locally disjointed parallel textile plies 7, 8 to form the protective sheath 6. elastic 4 is kept inside this protective sheath 6 so as to protect the elastic conductive wire 4, external aggressions and in particular the friction due to washing machine. As shown in FIG. 3, such protective sheaths 6 may be locally discontinuous so as to leave a portion of the elastic conductive wire 4 visible. A connection zone 15 for the elastic conductive wire 4 is then visible at the level of the outer face 14 of the garment 1. Such interruptions may in particular have a length of about 1 to 20 millimeters and preferably have a length of between 4 and 10 millimeters. Good results have also been obtained with interruptions of the protective sheath of a length of about 6mm. As shown in FIG. 4, the elastic conductive yarn 4 can be held at its end by means of non-conductive elastic binding yarns 13 positioned at least at a selvedge 10 of the elastic woven fabric 2. binding of the ends of the elastic conductive wire 4 then makes it possible to keep it stretched 30 inside the sheath 6 and facilitates the connection operations, in particular to carry out its welding or bonding with a sensor.
    [0011] It follows from the foregoing that an instrumented garment according to the invention has many advantages, and in particular: it is entirely made of textile materials and thus has a significant flexibility guaranteeing the wearer of the garment; the conducting wires have a freedom of movement inside the protective sheaths, which has the effect of further improving the flexibility of the garment; it can be washed without fear of damaging the protected conductor wires inside the sleeves; - it can present any type of design.
