    [0001] TECHNICAL FIELD The invention relates to the field of sportswear, in particular clothing for the practice of alpine skiing, and more specifically to alpine ski racing. More specifically, it relates to a garment of sticky or similar type, intended to cover the lower limbs, designed to optimize muscle performance. Prior art. In general, the practice of sport can be improved in certain aspects by the use of appropriate clothing. Thus, it is known that muscle efficiency can be increased by using garments that have areas that provide specific compression of the muscles they cover. Thus, examples of such garments are described in documents US 2013/011646 and WO 2012/614209. The garments described in these documents thus have the advantage of putting the muscles in a pre-tensioned state, which in particular limits the risk of injury due to too rapid elongation of the muscles. However, during the practice of alpine skiing and in particular ski racing, the rider is in a position where he has his knees strongly folded, which corresponds to a very specific configuration, and for which the clothes described in the aforementioned documents provide no particular advantage. SUMMARY OF THE INVENTION There is therefore a specific need for clothing assuring a pretension for the practice of alpine skiing and in particular of ski racing. Thus, the Applicant has designed an alpine skiing clothing which covers the bottom of the trunk and the lower limbs and which comprises different zones made with textiles having different elasticities.
    [0002] This garment is characterized in that it comprises a pair of strips of a first type, having a lower elasticity. These bands of the first type each extend from the inside of a thigh, passing above anterior area of the thigh, substantially at the level of the iliac crests, and to near the lower lumbar vertebrae. These bands are symmetrical with respect to the median plane of the garment. In other words, the invention consists in producing a garment which comprises a particular zone of lower elasticity thus ensuring compression, and which has a specific geometry. Specifically, this particular area begins on the anterior aspect of the thigh, and extends upwardly passing to the plumb, that is to say, partially covering the muscle sartorius. This zone then extends on the outer side of the thigh, above the iliac crests to circumnavigate the pelvis, to the lumbar region. In a first embodiment, these strips do not reach the spine, but are separated by a region of higher elasticity. In another embodiment, the two strips can meet at the spine, and form a continuous band in a symmetrical configuration from one thigh to the other. Thus, during the specific movements observed during the practice of alpine skiing, for which the legs are strongly bent, and the trunk inclined forwards, this characteristic zone consisting of the two bands of the first type is 3024020. 3 - powering up, and therefore exerts a higher pressure on certain muscles of the thigh, in particular the sartorius muscle, as well as the gluteus medius muscle and the multifidus muscle in the lumbo-pelvic region.
    [0003] This additional pressure applied improves the proprioception, as well as the balance of the tensions observed in the lumbo-pelvic region and in the thighs when the skier is in his characteristic position. These bands also limit the lateral rotation movements of the muscles of the thigh.
    [0004] In order to ensure a good efficiency of this area of low elasticity, in particular during the flexion of the knees, provision may be made for this band of the first type to extend below the knee. In a particular form, it can curve below the patella. Similarly, the efficiency can be improved by giving this first type band a configuration in which it is wider at its end, near the area of the lumbar vertebrae, so as to distribute the tension exerted in this area. region when flexing the trunk. In an advantageous embodiment, the garment may also comprise strips of a second type, of lower elasticity, which extends downwards from the top of the anterior zone of the thigh, through the anterolateral region. outer thigh. Thus, this band of the second type covers the outer quadriceps muscle where there is more intense activity when the skier experiences vibrations or shocks due to trajectories on non-perfectly flat surfaces. More specifically, this band of the second type can pass over the muscle vastus lateralis, and thus reduce the rocking movements of this muscle, with the effect of improving the balance and control of the legs during the phases of turns. This band of the second type can extend below the patella where it can join the band of the first type of the same thigh in a particular embodiment. Advantageously, in practice, this band of the second type can start upwards directly above the upper part of the sartorius muscle on which the band of the first type already passes. The zone delimited by these bands of the first and second type at the level of the thigh surrounds and compresses the rectus femoris muscle which acts to extend the knee and flex the thigh during repeated phases of turns during the evolution on the snow. In practice, it is considered that the compression effect exerted by the characteristic bands is measured by a pressure differential of at least 25% with respect to the more elastic zones of the garment. This characteristic band pressure is evaluated between 12 and 15 mm Hg, while the pressure exerted in the other regions of higher elasticity is rather less than 8 mm Hg. The different pieces of fabric can be juxtaposed with each other, by gluing or sewing. It is also possible to implant the characteristic strips superimposed on a more elastic garment covering the entire thighs and the pelvic region. The textiles used have chain length elongations which are greater than the elongation in the weft direction, so as to preferably allow elongation of the garment in the width direction greater than its elongation in the lengthwise direction. 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 of the fabric in support of the appended figures in which: FIG. 1 is a front view of the garment conforming to FIG. invention; Figure 2 is a side view of the garment of Figure 1; Figure 3 is a rear view of the same garment; Fig. 4 is a front 3/4 view of the same garment; Figure 5 is a rear view of the same garment. Detailed Description As illustrated in Figure 1, the garment according to the invention is similar to a tights having a first region (2) covering the bottom of the trunk or pelvis. This zone (2) is extended downwards by two zones 3 and 4 covering the thigh to below the knee. Of course, the garment can extend to the bottom of the leg. Since this region is not directly related to the invention, it will not be described in detail. It can also extend upwards by covering the bust, and include shoulder straps if necessary. The garment is made by assembling pieces to effectively cover the body of the skier.
    [0005] According to the invention, the garment has strips (10) and (20) which have a lower elasticity than the rest of the garment. More specifically, the different textiles used for the garment may be based on polyamide and in particular Nylon ° and elastane, with an overall weight of 200 g / m2 for example and which has a proportion of elastane more low, typically of the order of one half, for the less elastic textile. By way of example, the least elastic textile may comprise a proportion of 18% elastane for 82% of polyamide, while the more elastic textile has 30% elastane for 70% of polyamide.
    [0006] Elasticity measurements made on the fabric of lower elasticity, developed according to the UNI EN 14704-1 standard, give an elongation of 3.6 kg force between 85 and 115%, typically 100% in the transverse direction. The 3.6 kg force elongation has a value between 51 and 69%, typically 60% in the longitudinal direction. Similarly, the form measured at 40% elongation is between 455 and 845 gram-force (gf), and typically close to 650 gf in the transverse direction, and between 840 and 1660 gf, and typically close to 1200 gf in the longitudinal direction. With regard to the textile with higher elasticity, the same tests give a transverse elongation of between 208 and 282%, typically close to 245%, and in the longitudinal direction of between 187 and 253%, typically close to 220%. Equivalent tests give a measured force at 40% transverse elongation of a value between 210 and 390 gf, close to 300 gf, and in the longitudinal direction of values between 175 to 325 gf and typically close to 250 gf. As illustrated in FIG. 1, the band of the first type (10) begins below the knee, in its internal part, and rises on the internal face of the thigh. This band then has an area (12) which is in line with the sartorius muscle. This band (10) extends upwardly widening to pass near the iliac crests, as can be seen in Figure 2. This band (10) 20 continues to expand towards the back of the garment, and stops near the lumbar area. It is connected to a zone (14) more elastic, and advantageously breathable located vertically above the lumbar vertebrae. In a particular embodiment not illustrated, the path of the first type of strip 25 can then be extended by a symmetrical band to join the underside of the opposite knee, and thus form a continuous band from one knee to the other. Complementarily, the garment also comprises a band of a second type (20), which originates, as illustrated in FIGS. 1 and 4 below the knee level, preferentially on its external region in an area (21) where it joins zone (1) of the first type band (10). Alternatively, this band 3024020 -7- can start below the patella. This second band (20) extends upwards along some quadriceps muscles and more precisely the vastus lateralis muscle. In the upper part of the thigh, this band curves inwards in an area (23) which connects to the first type band (10) at the upper part of the reetus fenwris muscle. Of course, the two legs of the garment each have a band of the second type (20). The strips of the first and second type are connected by at least one strip of polymer film (31-33), typically based on superimposed polyurethane 10 and bonded to the most elastic textile, which make it possible to limit the transverse spacing between the two strips (10,20), and thus maintain the best circumscribed muscles. A similar film strip (35) can also connect the two first and second type strips below the knee.
    [0007] Complementarily, the garment may comprise zones (40) made of a different textile, having a higher rate of deferment, allowing the heat removal in the fold of the knee. Similarly, the area (50) covering the patella can be made by a different part 20, to adapt to the shape of the knee. It follows from the above that the garment according to the invention has multiple advantages, in particular that of ensuring the maintenance of the muscles of the thigh which are particularly stressed when the skier is in the bent position.
    [0008] These thigh muscles are somehow mechanically coupled to the muscles of the lower back particularly to increase lumbar support. They improve the sensation of reactivity, and ensure a rapid contraction of the muscle. This results in better cornering curves and thus improved skier performance. Likewise, such conditioning of the muscles allows a better recovery of the fatigue as well as a limitation of the risk of occurrence of muscular accidents.
