  The fixed sub-module comprises lugs provided with holes through which projecting studs integral with the body and on which are screwed nuts.

  The zones and fixing members of the sub-modules respectively fixed and mobile, called to cooperate, being made in different manufacturing units, it follows that the establishment and adjustment in position of said submodules are delicate.

  In a known manner, the adjustment comprises several steps, including the temporary placement of the fixed sub-module by pre-screwing the nuts on the studs, then putting in cooperation the respective elements of the fixed and mobile sub-modules, separating the sub-modules by opening the tailgate, and final tightening of the nuts.

  These steps take time and are labor intensive.

  In addition, some modules include two sub functional modules on the same board (motor, shaft, lock). In configurations where the module is inclined, its relatively high weight induces a torque causing its fall. Temporary maintenance, to achieve the position adjustments, under these conditions, is all the more difficult and / or requires to take additional precautions.

  The present invention aims to remedy these problems, and proposes a device that allows to temporarily maintain the module reliably, while allowing the adjustment of its position, simply and economically.

  In the case where said adjustment hole is provided on a fastening lug integral with the module, the clip comprises guiding means, in the form of at least one fin able to bear with friction against said fixing lug, and in particular against the lateral edge of the latter, or at least one projecting portion capable of cooperating with a groove provided on said said tab.

  In order to avoid an accidental displacement of the device, with respect to the fixing lug, it comprises temporary locking means in position on the fixing lug, such as an elastically deformable part and provided with a projecting element capable of to cooperate with a recessed portion complementary to the bracket of the module.

  To avoid accidental tearing of the clip, the bracket has a notch adapted to receive the bottom of the clip so that it does not exceed the edges of the tab. According to a second example, the friction means consist of a resiliently deformable material member occupying at rest the internal space of the adjusting hole, and more precisely a pellet provided with a central recess of smaller dimension to said male member of the support. The deformable material is preferably metal or plastic.

  According to a third example, the friction means consist of at least one element bearing against the wall of the adjusting hole, and elastically deformable. Preferably, said element comprises a ring, preferably made of a material such as metal or metal. plastic.

  According to a fourth example, the friction means consist of at least one deformable plate, fixed on the module and partially covering the adjustment hole, the passage of the male member creating by deformation of said plate a friction.

  According to a second family of embodiments, said friction means are an integral part of the walls, or edges of said adjustment hole.

  Specifically, the surroundings of the wall of the adjusting hole are designed so as to allow a preferably elastic deformation of the adjustment hole, and in particular by providing an area of weakness at the edges of said hole, for example in the form of at least a strip of material separating said adjusting hole and a recessed area disposed in proximity.

  Advantageously, the device comprises means for attaching a nut intended to cooperate with said male member of the support, said means allowing the displacement of the nut following at least the direction of screwing. These means may be formed of at least one deformable tongue.

  The invention also relates to a mechanical functional module, including a first sub-module intended to be fixed on a fixed support, such as a vehicle body, and to cooperate with a second sub-module integral with a movable element, such as a tailgate or a rear window of a vehicle, and intended to be positioned against or near the edge of the box, said module comprising a device for its fixing and / or temporary retention on the support while allowing its adjustment in position, the device being characterized in that it comprises means capable of generating friction forces likely to prevent the respective displacement of the module and the male member, below a given threshold force.

  To avoid accidental tearing of the clip, the bracket has a notch adapted to receive the bottom of the clip so that it does not exceed the edges of the tab. In a particular application, the module comprises a first submodule in the form of an engine block and an engine output drive shaft, and said second sub-module includes a shaft and the associated wheelhouse of a windscreen wiper.

  Figures 15 and 16 show respectively another alternative embodiment of the device associated with a staple (in perspective) and the tab of the associated module (top view).

  FIG. 1 shows a partial schematic sectional view of a motor vehicle 1 for its rear part, 2 comprising a rear panel 3 of a bodywork, a rear bumper 4, a rear window 5 in the form of a window pane articulated on a horizontal axis 6 located on the top of the vehicle near the roof 7.

  A mechanical module 8 is fixed on the rear panel 3 of the bodywork, linked to the vehicle body. The mechanical module includes for example a lock 9 fixed to the bodywork, and an associated striker 10, and fixed on the bezel 5.

  The latter pivots in rotation about the axis 6, between two extreme positions: a closed position shown in solid line in Figure 1 where it closes the opening, and the latch 10 is engaged in the lock 9, and an open position dashed and referenced 5A, where the striker 10 (bearing the reference 10A) is disengaged from the lock 9.

  In the closed position of the telescope (solid line), the lock 9 and the keeper 10 are in cooperation along a substantially horizontal axis 11 in the example described.

  Figure 2 shows a detailed perspective view of an exemplary module to which the invention is applicable. The module 12 comprises a first sub-module 13 comprising an electric motor 14 for wiper drive, and an electric lock 15, mounted on a plate 16. The second sub-module 17 comprises on the one hand a mechanical block 18 such that a compensate on the other hand (for driving a windscreen wiper disposed on a rear window), and a lock striker 19 associated with the lock 15. The step 18 and the striker 19 of the second sub-module 17 are mounted also on a turntable 20.

  The module 12 including the first and second submodules respectively 13 and 17, fixed to each other mechanically, is intended to be fixed on a support such as the bodywork or the body 21 of a vehicle, by the intermediate studs 22, 23 and 24, projecting from the general plane of the box 21. The mounting plate 16 of the first sub-module comprises fastening tabs 25, 26 and 27 each provided with a hole, respectively 28, 29 and 30. The holes are of oblong shape, in a common direction XX, and are intended to cooperate with the studs 22, 23 and 24. The dimension of the adjustment holes 28, 29 and 30, in the direction perpendicular to the direction XX, is barely greater than that of the studs to allow the passage of the latter without friction, as known per se.

  FIG. 2 shows the module 12 placed on the body 21 of the vehicle, the studs passing through the holes 28, 29 and 30 provided on the tabs 25, 26 and 27 of the plate 16.

  The direction of the holes 28, 29 and 30 allows a displacement of the plate 16, and therefore of the module 12, in the single direction X-X. The deflection of the module 12 in translation, defined by the length of the holes, corresponds to the possible position amplitude, and allowing the adjustment in position before final placement on the body 21.

  FIG. 3 shows a partial perspective view of a fastening lug 25 provided with a hole 28 and on which the device of the invention, in the form, in the present case, can be put in place, of a temporary holding clip 31 shown in FIG. 4A. The distal or free end of the tab 25 is referenced 25 A. The clip 31 is generally U-shaped and comprises a base plate 32 provided with a circular hole 33, a return panel 34 perpendicular to the base plate 32, two lateral tabs 35 and 36, parallel to each other and substantially to the plane of the base plate 32, and a support pad 37 integral with the free end of said tabs 35 and 36 and substantially parallel to the base plate 32. The shoe 37 has a hole 38 of diameter substantially identical to that of the hole 33 of the base plate 32 and located opposite it (the two holes having a diameter very slightly greater than that of corresponding dowel, to allow the passage of it without friction).

  FIGS. 4B and 4C show the clip 31 in place and associated with the tab 25 so that the latter is introduced into the space delimited by the base plate 32 and the pad 37, while carrying by its side edges 41 and 42 against lateral fins 39 and 40 of the base plate 32. The said fins 39 and 40 provide guidance of the clip 31 relative to the tab 25, bearing against the lateral flanks of the latter.

  As shown in FIG. 3, the tab 25 comprises a groove 43 perpendicular to the axis XX and capable of receiving, when the clip is in place (FIG. 4B), a corresponding elongate protuberance 44. This arrangement allows the temporary locking and detachable in position, the clip on the tab 25. This avoids inadvertent tearing of the clip 31, while allowing, by applying a reasonable force, the movement of the clip relative to the tab 25 according to the arrow f (XX axis).

  The shoe 37 bears with friction against the upper face of the opposite side to the body 21 of the vehicle, the leg 25.

  The shoe 37 is thus arranged cantilevered and held by two end lateral wedges on the tongues 35 and 36 laterally deformable elastically.

  FIG. 5 shows another embodiment of the staple 45 comprising substantially the same elements as the staple 31 of FIG. 4A, except that the shoe 37 is connected directly to the perpendicular return panel 34 (FIG. the lateral tabs 35 and 36 being omitted). The staple 45 is put in place in the same manner as that previously described, the shoe 37 bearing by friction against the upper face of the tab 25.

  Figure 6A shows another embodiment of the staple 46 and having substantially the same structure as the staple 45 of Figure 5 with the exception of the two lateral guide vanes 39 and 40 which have been omitted. The guide, in this embodiment, is formed by two longitudinal protuberances 47 and 48 provided on the face of the plate 32 facing the inside of the clip. The tab 25, as shown in Figure 6 B, has two grooves 49 and 50, and each of which being capable of receiving the protrusion 47, respectively 48.

  With reference to FIGS. 7A and 7B, the steps of adjustment in position of the plate 16 carrying the first sub-module 13 mechanically secured to the second sub-module 17 are described. These two figures only show the tab 25, the associated pin 22 and FIG. the staple 31, it being understood that the other tabs, studs and staples are arranged in the same manner and have the same movements.

  At first, the operator places the staple or staples 31 on the corresponding tabs 25, 26 and 27 by sliding the staple on the tab. The clip is placed at an initial position where the two respective holes, 33 of the base plate 32, and 38 of the friction pad 37, are arranged, with respect to the adjustment hole 28 of the tab 25, at the end. distal of said paw.

  Then the operator places the module, including the tabs 25, 26 and 27, provided with their respective clips, so that the studs pass the two holes of the clip and the adjustment hole of the tab, to arrive at the position shown in Figure 7 A, where the tab rests on the body 21 of the vehicle.

  For reasons of convenience, the staples in Figs. 7A and 7B are shown in transparency.

  It will be understood from FIG. 7A that the tab 25, by the relative arrangement of the clip 31 and the stud 22, holds the tab and thus the plate 16 and the module in a stable and reliable position.

  This is all the more significant in the example described where the module is relatively complex and has several elements leading to a significant weight. In the event that the area of the vehicle body where the studs are arranged is inclined, the weight of the module generates a tilting torque which would cause the module to fall in the absence of the device of the invention.

  Adjustment operations are continued in a subsequent step by closing the rear window, on which is mounted the second sub-module (wiper drive and striker). The strike interacts with the lock, the bearing cooperates with the motor output shaft disposed on the first module, and the assembly is thus set up relatively by moving the tab 25 relative to the assembly. crate / stud / clip, which remain fixed. This leads to the position of Figure 7 B where the tab has moved towards the inside of the vehicle, to arrive at a position of the stud 22 intermediate in the hole 28 provided on the tab. This position corresponds to the optimal operating position of the mechanical components (latch, lock, motor, step, etc.) of the module. The next step is to screw nuts on the studs to permanently fix the position of the tab 25 relative to the body / staple / stud assembly (this step is not shown for reasons of clarity).

  In an advantageous embodiment, shown in Figures 8A and 8B, each clip 31 has tabs 51 and 52 side, fixed at one end to the clip; on the other end of each tongue is held a nut 53, free to rotate.

  At rest, in the position shown in Figure 8A, the nut is disposed in the axis and just above the corresponding pin 22, after screwing the nut 53 it leads to the position shown in Figure 8 B where the nut 53 is screwed and firmly holds the assembly, stud / clip / tab, the downward movement of the nut being authorized by the deformation of the lateral tongues 51 and 52.

  Figure 9 shows an alternative embodiment of a bracket 25 on which is disposed a staple 31 such as that described above. In order to prevent any inadvertent removal or tearing, in particular during transport or by accidental movement, of the staple 31 with respect to the tab 25, it includes a notch 54 provided on the end intended to abut against the bottom of the U formed by the staple 31.

  Thus, the clip does not protrude from the tab (on the side of the bottom of the U formed by the staple). The clip can not accidentally catch on a projecting external element or during a shock for example.

  FIGS. 10A and 10B show an alternative embodiment of the device of the invention, shown hitherto in the form of a staple 31.

  According to this variant, the device 55 of the invention comprises an oval ring 56, of shape complementary to the hole 28 provided on the tab 25, so that the ring 56 bears against the edges of the adjustment hole 28 (FIG. 10B) . The thickness in the transverse direction of the ring 56 is of the order of 1 millimeter.

  The ring 56 is associated with a flat base 57 having a central hole corresponding to the inner recessed portion of the ring 56. The base 57 is able to bear against one of the faces of the lug 25, once the device 55 in place (Figure 10B).

  The ring 56 has holding claws 58 to 61 and projecting from the free edges of the ring portion 56 (opposite the base 57). The claws 58 to 61 make it possible to hold and lock the assembly 55 (ring 56 and base 57) on the adjustment hole 28 of the lug 25.

  The dimension of the ring 56 in the direction transverse to the longitudinal axis of the adjustment hole 28, is such that the corresponding stud 22, after penetrating the hole 28, allows the maintenance by friction of the tab 25 relative to the stud 22.

  The device 55 and in particular the ring 56 is preferably made of a material such as metal or plastic.

  In FIG. 11, another variant of the temporary deformation holding device is shown.

  The device consists in this case of a plate 62 whose central portion is pressed against the underside of the tab 25 (the face bearing against the vehicle body), while the lateral sides of the plate 62 are folded on the upper face of the tab 25 to form two flanks 63 and 64 projecting substantially (over a length of about 1 millimeter) over the hole 28.

  Figure 11 shows the stud 22, the passage through and through the hole 28, causes the deformation, which may be elastic or inelastic, of the end edges 65 and 66 of the flaps 63 and 64 of the plate.

  This variant results in the same result as the embodiments of the device of the invention described and shown previously.

  Figures 12 A and 12 B show another variant of the device of the invention, by elastic deformation.

  In this variant, the device consists of a pellet 67 of deformable elastic material such as, for example, elastomer, and filling almost the entire hole 28 of the tab 25 with the exception of a longitudinal central slot 68 ( in the axis of the hole 28). FIG. 12B shows the tab and the pellet after the corresponding stud 22 has been put in place and has penetrated into the hole 28. This causes the lips of the slot 68 to deform and thus exerts a pressure now by friction with the tab 25 relative to the stud 22, and this temporarily or movable.

  FIGS. 13 and 14 show two other embodiments of the temporary fastening device of the invention, by means integrated in the tab itself, and not reported as the variants of embodiment shown hitherto.

  In FIG. 13, the tab 25 is provided with a central recess 69, which includes the adjustment hole 28 of the other embodiments described above, so that the tab forms a kind of fork with two branches 70 and 71 leaving the recess 69 in the center.

  This recess has three successive parts starting from the distal end of the tab 25: a first trapezoidal part, narrowing towards the proximal end of the tab 25, 72, a second portion in a rectangle corresponding substantially to the hole of setting 28 and finally a flared end portion 73, wider than the width of the rectangular central portion 28.

  It is understood that the lug 25 is first arranged so that the stud 22 in the trapezoidal portion 72, then by sliding of the lug 25 the stud enters the adjustment hole 28 where the friction induced by the respective dimensions of the hole 28 and the stud 22 allows the maintenance of the tab 25 relative to the stud 22.

  It is also understood that the end flared portion 73 of the recess 69 allows the elastic deformation, of the order of a few hundredths of a millimeter, and therefore the separation of the branches 70 and 71 of the fork formed by the tab 25.

  FIG. 14 represents a variant of the device in the same order of idea as that represented in FIG. 13, namely that the tab 25 is shaped in such a way that the edges or walls of the adjustment hole 28 can be very slightly deformed to exert a pressure and thus a friction on the stud 28 while allowing the movement of the tab. In the form of FIG. 14, the tab 25 comprises a hole 28 as previously described and also two longitudinal slots 75 and 76 along the axis xx, arranged on either side of the hole 28, and in such a way as to delimit between they and the edge of the hole 28, a material bridge respectively 77 and 78, of the order of 1 millimeter. The two material bridges are areas of least resistance, mechanically, which will be called to deform very slightly during the passage of the stud, to exert pressure on it.

  FIG. 15 shows in perspective another variant of the device of the invention, in the form of a staple 31, comprising a base plate 32 and a shoe 37, both parallel and opposite, connected by a return panel 34. The base plate 32 has a hole (concealed and corresponding to the reference 33 in Figures 4A and 5) and the shoe 37 has a hole 38, said holes 33 and 38 being arranged opposite and a diameter substantially equal to that of a dowel (not shown) similar to one of those (references 22, 23 or 24) shown in Figure 2.

  A friction ring 79 is issued from the clip and more specifically to the base plate 32 opposite the holes 33 and 38. The diameter of the inner hole corresponds to that of said holes 33 and 38.

  The ring 79, has on the outside of its axial walls (along the axis of the holes 33 and 38), protrusions, for example four regularly distributed, and three of which are visible in Figure 15 (references 80, 81 and 82).

  The clip 31 of FIG. 15 is capable of being fixed on a tab 25 of the module, as shown in FIG. 16. The tab 25 comprises an adjustment loop 28, of elongate shape in the direction XX, the walls of which Inner cases comprise notches 83, 84 and 85 or recesses of arrangements and forms complementary to the protuberances 80, 81 and 82 of the ring 79 of FIG.

  The clip 31 is fixed on the tab 25 by moving the shoe 37 away from the base plate 32 (by acting on the elasticity of the clip), then placing the ring 79 in the part of the adjustment hole 28 (of the tab 22), so that the protuberances 80, 81 and 82 of the ring 79 cooperate with the notches 83, 84 and 85 of the tab 25. It then releases the shoe 37 which then bears against the corresponding surface of the leg 25.

  When placing the module on the body, as previously described, a stud (not shown) enters the hole of the base plate 32, the central hole of the ring 79 and the hole 38 of the shoe 37.

  The engagement of the protuberances with the notches makes it possible to hold the staple 31 in rotation on the tab 25. When adjusting the position of the module, as explained above in relation to the other figures, the friction forces created between the outer wall the ring 79 and the inner wall of the adjustment hole 28 of the tab 25 brake or prevent the relative movement of the clip and the stud.

  The ring 79 is made of a deformable material, preferably elastically, such as for example plastic or metal.
