    [0001] FIELD OF THE INVENTION The invention relates to an arrangement of means for fixing an element on a double wall. More particularly, the invention relates to an arrangement of fastening means of a roof bar on the roof of a motor vehicle. [0002] Some motor vehicles are equipped with longitudinal roof bars. These bars are generally fixed to the roof of the vehicle at such a distance from the lateral edges of the roof that the feet of the roof bars are inclined towards the outside of the roof. It results from this inclination and the clearance between the fastening means and the edges of orifices formed in the roof to receive the fastening means, as well as the flexibility of the lining of the roof a tendency of spill roof bars as soon as they are under the load of objects positioned on the roof. This spill can also be described as a rotation of each of the roof bars around their respective longitudinal axis. The object of the invention is to provide a solution that eliminates this rotation of the roof bars. The object of the invention is achieved with an arrangement of fastening means of an element such as a roof bar on a double wall structure such as the roof of a motor vehicle, the fastening means comprising for each point of attachment of the element on the structure a securing shaft integral with the element and passing through a first of the two walls of the structure by a first port to bear on the second of the two walls, and a set screw / nut whose screw is housed substantially coaxially inside the fixing barrel and protrudes from the two opposite ends of the fastening barrel so as to pass through the second wall of the structure through a second orifice, the fastening barrel having an internal clearance between the screw of the screw / nut assembly and the inside face of the fixation barrel and the outside diameter of the fixing barrel being substantially equal to the diameter of the first orifice, so that the fixing barrel ion passes through the first hole substantially without clearance. According to the chosen embodiment of the arrangement according to the invention, the latter can also have at least one of the following characteristics, considered alone or in combination: the fixing shaft is made of an incompressible material; the fixing shaft is a steel anti-creep ring; the fixing shaft is secured to the element by overmolding; the nut of the screw / nut assembly is retained in place under the second wall; the nut of the screw / nut assembly is crimped under the second wall; the nut of the screw / nut assembly is welded under the second wall; the difference between the outside diameter of the fixing barrel and the diameter of the first orifice is less than 0.5 mm. The object of the invention is also achieved with a roof bar for a motor vehicle having a double-walled roof, comprising at least two feet and fastening means comprising, for each foot, a fixed mounting shaft of the foot of the roof bar and passing through a first of the two walls of the roof by a first hole for bearing axially on the second of the two walls, and a screw / nut assembly whose screw is housed inside the fixing shaft and protrudes from opposite ends of the attachment barrel so as to pass through the second wall of the structure through a second orifice, the attachment barrel having a clearance between the screw of the screw / nut assembly and an inner face of the attachment barrel and an outer diameter of the fixing barrel being substantially equal to the diameter of the first orifice, so that the fixing barrel passes through the first hole substantially without play. [0007] Similarly, the purpose of the invention a motor vehicle equipped with two longitudinal roof bars is reached, the motor vehicle having a double-walled roof and each of the roof bars having at least two feet by which it is fixed on the roof by means of fixing comprising, for each foot, a fastening shaft secured to the foot of the roof bar and passing through a first of the two walls of the roof by a first hole to bear axially on the second of the two walls, and a screw / nut assembly including the screw is housed inside the fixation barrel and protrudes from the two opposite ends of the fixation barrel so as to pass through the second wall of the structure through a second orifice, the fixing barrel having a clearance between the screw of the screw / nut assembly and an inner face of the attachment barrel and an outer diameter of the attachment barrel being substantially equal to the diameter of the first orifice, so that the attachment barrel The other features and advantages of the present invention will appear in the explanatory description which follows, with reference to the accompanying drawings given solely by way of example and in which: FIG. 1 shows a longitudinal roof bar fixed to the roof of a motor vehicle; FIG. 2 shows a traditional arrangement of means for fixing the roof bar of FIG. 1, that is to say without recourse to the FIG. 3 shows an arrangement according to the present invention of fixing means of the roof bar of FIG. 1. FIG. 1 represents, in a perspective view, a longitudinal roof bar 1 fixed. on the roof 2 of a motor vehicle. The roof 2 comprises a roof plate 21 constituting the visible portion of the roof and a roof lining 22 located below the roof panel 21 and spaced from the latter. The roof lining 22 is secured to the sides of the body 3 of the vehicle. The roof bar 1 is fixed on the roof 2 with fastening means which comprise screw / nut assemblies 4 (see FIG. 2) but without a direct connection with the roof plate 21. [0010] Indeed, as is apparent from FIG. Figure 1 and in more detail of Figure 2, the roof bar 1 comprises a bar body 11 and a bar cap 12 which extend over the entire length of the roof bar 1. The roof bar 1 comprises in addition two feet 13, sometimes even three feet, which serve both to a positioning of the body of bar 11 at a distance above the roof 2 of the vehicle and the fixing of the roof bar 1 on the roof 2 of the vehicle. The feet 13 and the body 11 are generally made in one piece of a rigid plastic material. According to the exemplary embodiment shown, the feet 13 are provided with covers 14. [0011] FIG. 2 shows in greater detail that the roof bar 1 is fixed on the roof 2 through the feet 13 with fastening means comprising , for each of the feet 13, one of the screw / nut assemblies 4 and a fixing barrel 15 in the form of a sleeve and which is made of an incompressible material, for example steel. The fixing shaft 15 extends the foot 13 in the direction of the mounting axis, that is to say perpendicularly to the general plane of the roof 1. The screw / nut assembly 4 comprises a screw 41, a nut 42 and a washer 43. And the attachment barrel 15 whose inner diameter is only slightly larger than the nominal diameter of the screw 41, is secured to the foot 13, for example by overmolding the fixing shaft 15 with the rigid plastic material of the body of bar 11 during the realization of the latter. For the fixing of the roof bar 1 on the roof 2 of the vehicle, the roof plate 21 is provided with an orifice 23 that the fixing shaft 15 crosses to bear axially on the roof lining 22 and the roof lining 22 is provided with an orifice 24 that the screw 41 passes through to be engaged in the nut 42 fixed on the underside of the lining 22, for example by welding or crimping. The foot 13 does not rest on the roof plate 21, an annular seal 16 is disposed around the periphery of the orifice 23 and compressed by the foot 13 during the fixing of the roof bar 1. [0013 The positions of the feet 13 and consequently also those of the fixing barrels 15 with respect to the rod body 11 and the positions of the orifices 23 of the roof plate 21 being subjected to manufacturing tolerances, a radial clearance J1 is provided of each side of the fixing barrels 15 between each of the fixing barrels 15 and the edge of the corresponding orifice 23 to obtain a correct fixing of the roof bar 1 on the roof 2: in the case represented by a roof bar 1 with two feet 13, it is to be able to fix the roof bar 1 parallel to the edge of the roof 2 and in the case of a roof bar with three feet, there is added the need to compensate for a possible defect d alignment of the three legs and / or the three orifices with each other. The game J1 can reach values of the order of 3 mm. However, as already explained above, in an assembly according to that of Figure 2, the existence of a clearance between the fixing shaft 15 and the edge of the orifice 23 gives the bar roof 1 a tendency to spill. On the other hand, the existence of a clearance is necessary to compensate for the consequences of manufacturing tolerances. As is apparent from Figure 3, the present invention overcomes this contradictory situation by moving the game from the outside of the mounting barrel inwardly thereof.
    [0002] Thus, each fixing shaft is firmly held in the orifices of the roof plate 21 and does not move in the latter under the load of objects positioned on the roof 1. This provision of the invention can be obtained from two ways. According to the first, the fixing barrels 15 of the assembly of FIG. 2 are used and the corresponding orifices of the roof plate 21 are formed with a smaller diameter, substantially equal to the outside diameter of the fixing barrels 15. According to the alternative way the orifices 23 are conserved and fastening drums having an outside diameter larger than in the assembly of FIG. 2 are used, that is to say substantially equal to the diameter of the orifices 23. It is this second way which will be described below. Indeed, Figure 3 shows - as Figure 2 - the fixing of a roof bar 1 on a roof 2 of a motor vehicle with fixing means comprising, for each of the feet 13 of the bar of roof 1, a screw / nut assembly 4 and a fixing barrel. The same reference numbers are used for the same parts or elements. Thus, as before the invention, the foot 13 is disposed on the roof plate 21 by means of the seal 16 surrounding the orifice 23 in which is engaged a fixed mounting shaft 17, for example by overmolding, of the foot 13. [0019] Since a fixing barrel 17 having substantially the same diameter as the orifice 23 is used, a clearance J2 is obtained between the attachment barrel 17 and the edge of the orifice 23, which is ideally zero. Taking into account the manufacturing tolerances, the clearance J2 will be at least close to zero, that is to say it does not exceed 0.5 mm. The fixing barrel 17 also has an inside diameter that is much greater than the nominal diameter of the screw 41 and thus has an internal clearance or backlash J3 measured from the coaxial position of the screw 41 inside the fixing barrel. 17. In other words, the difference between the inside diameter of the fixing barrel 17 and the nominal diameter of the screw 41 gives an internal clearance J3 in a radial direction on each side of the screw 41, thus in total a set of twice J3 which makes it possible to perform the same compensations and alignments as the set J1 of the solution prior to the invention. The advantage of the present invention is that the stamping tool for the production of the roof plate 21 does not need to be modified and that only the fixing shaft 15 of the previous design must be replaced by the attachment barrel 17 according to the invention, that is to say by a sleeve-shaped piece having inner and outer diameters larger than those of the anterior fixation barrel 15. [0021] In addition, made of the absence of play between the fixing shaft 17 and the edge of the orifice 23 of the roof plate 21, the recovery of forces acting on the roof bar 1 is instantaneously on the roof plate 21 in the orifice 23, which prevents any rotational movement of the roof bar 1 about its longitudinal axis. And even if the game J2 is not exactly zero but has a value not exceeding 0.5 mm, the consequences for the recovery of forces by the roof plate 21 are negligible because of the relatively large distance h between the roof plate 21 and the roof lining 22, which is of the order of 20 mm. Thus, advantageously thanks to the provisions of the present invention, not only the fixing drums 17 of a roof bar 1 are wedged radially in their respective orifice but, in addition, the screws 41 can be correctly positioned relative to the corresponding nuts 42. As a result, the cant loads are no longer essentially supported by the lining of the roof but distributed between the roof plate, the roof lining and the fixing drums and there is no longer a tendency for a rotation of each of the bars. roof around their respective longitudinal axis.
