    [0001] The present invention relates to a clip for fixing a panel to a support, in particular in a motor vehicle. BACKGROUND OF THE INVENTION The invention also relates to a method of implementing such a fastening clip. The invention also relates to automotive equipment comprising a support, a panel and such a fastening clip. In practice, it is known to use such a clip to replace a screw system, in particular for fixing vehicle interior lining or casings under vehicle body. The screw system comprises for example a plastic part called "grommet" and a metal screw. The grommet is assembled on the support, then the screw is screwed in this grommet, through the panel to fix, by action of a screwdriver.
    [0002] FR-A-22789455 discloses an example of a fastening clip, molded in one piece of plastic material. The staple includes a rigid core and two curved flexible wings that are connected to the core. Each wing can bend by plastic deformation to allow snapping of the clip into a hole in the panel. The object of the present invention is to provide a variant of fastening clip.
    [0003] For this purpose, the subject of the invention is a fastening clip for a panel on a support, in particular for an automobile equipment, characterized in that: the clip comprises a core and a cage forming two distinct parts centered on a central axis; the nucleus has a head and a body; the body has an outer profile in the form of a helix, tapered on either side of a plane of inflection transverse to the central axis; the cage has a base and a torsion bar; the torsion bar is housed in the core; the core and the torsion bar comprise complementary means for fastening in rotation around the central axis; and the torsion bar is elastically deformed upon rotation of the core about the central axis. Thus, the invention makes it possible to obtain a staple which is simple and practical to implement, having improved mechanical strength, by choosing materials optimized for the core and for the cage. The clip can be pre-positioned on the panel to be fixed, then implemented by simply snapping on the support. The clip advantageously replaces a screw system, which avoids the use of a screwdriver and saves time during assembly. In addition, the use of a staple according to the invention is economically advantageous. According to other advantageous features of the invention, taken separately or in combination: the head of the core and the base of the cage comprise complementary abutment elements, limiting the relative rotation between the head and the base, whereas the bar of torsion is elastically deformed and that the core pivots around the central axis. - The propeller comprises reliefs and recesses which are connected by edges provided to slide against the support. - The base has clipping hooks on the support. - The clip comprises a sealing flange fixed to the cage and provided to bear against the support. - The clip comprises a seal attached to the core and disposed in abutment against the cage. The cage comprises at least one arm, preferably two arms, connecting the base to a distal end of the torsion bar. - The body of the core comprises at least one groove adapted to receive a lug formed on the arm or at least one of the arms, preferably the body has two grooves provided to each receive a lug formed on one of the two arms. The invention also relates to a method of implementing a clip as defined above. The method is characterized in that it comprises successive successive phases: a) a preparatory phase of bringing a panel and a support each having a receiving orifice of the staple, which is introduced into the hole of the panel; b) a fixation phase consisting in introducing the clip through the orifice of the support, this fixation phase comprising successive successive steps: b1) while the core passes through the orifice of the support, the propeller is driven into contact the support in a first direction of rotation about the central axis and the torsion bar is elastically deformed about the central axis; b2) once the plane of inflection of the propeller has passed through the orifice of the support, the torsion bar is elastically deformed until it returns to its initial configuration, while driving the core in a second direction opposite to the first direction of rotation around the central axis.
    [0004] According to a first embodiment of the preparatory phase, the staple is positioned on the panel, being introduced into the hole of the panel, before bringing the panel and the support closer together. According to a second embodiment of the preparatory phase, the clip is positioned on the panel and the support, being introduced through the orifices of the panel and the support, after the approaching of the panel and the support. The invention also relates to automotive equipment, comprising at least: a support; a panel intended to be fixed to the support; and a fastening clip as defined above.

In Figures 1 to 13 is shown an automotive equipment 1 according to the invention, comprising a panel 2, a support 3 and a fastening clip 10, also according to the invention. The equipment 1, the panel 2 and the support 3 are partially shown in FIGS. 1 to 7 for the purpose of simplification. By way of non-limiting example, the equipment 1 may be a motor vehicle door, the panel 2 is a trim panel and the support is a metal sheet.
    [0006] The clip 10 is provided to fix the panel 2 on the support 3. Depending on the intended application, the equipment 1 may comprise one or more fastening clips 10 of the panel 2 on the support 3. The panel 2 comprises two opposed flat surfaces 2a and 2b, and a through hole 2c formed between the surfaces 2a and 2b. The orifice 2c has several parts 2d and 2e interconnected, namely a central portion 2d of rounded shape and two side portions 2e of rectangular shape. The orifice 2c is preferably formed by punching or molding through the panel 2. The support 3 comprises two opposite flat surfaces 3a and 3b, and a through hole 3c formed between the surfaces 3a and 3b. The orifice 3c has a rectangular shape with rounded inner corners. The orifice 3c is preferably formed by punching through the support 3.
    [0007] In practice, the panel 2 and the support 3 may have curved surfaces. For example, the panel 2 may have a concave surface 2a and a convex surface 2b. The clip 10 comprises a core 12 and a cage 14, forming two separate parts.
    [0008] The core 12 may be made of polyamide (PA 6.6) with a fiberglass filler (30% by weight), while the cage 14 may be made of polyacetal such as polyoxymethylene (POM), or polyamide (PA 6.6 ). When the clip 10 is assembled, the core 12 and the cage 14 are centered on a central axis X10. The longitudinal direction of the clip 10 is defined parallel to this axis X10. The core 12 has a head 20 and a body 30 having a helical shape 32. The core 12 also has an inner housing 16 which extends through the head 20 and the body 30 along the axis X10. The cage 14 comprises a base 40, a torsion bar 50 and two arms 60. A proximal side is defined at the level of the head 20 and the base 40, as well as a distal side opposite the head 20 and of the base 40. The bar 50 is inserted into the housing 16, while the head 20 is positioned in the base 40, during the assembly of the clip 10. As shown in Figures 8 to 10, the head 20 comprises a main part 21, a flange 22, a connecting part 23 and an internal cavity 24. The parts 21 and 23 each have a cylindrical shape, with a slightly smaller diameter for the part 23. The main part 21 supports the collar 22 and two stop members 25, detailed below. The flange 22 has a disc shape and is situated on the distal side of the head 20. The flange 22 has two protuberances 29 on its distal face, intended to cooperate with the base 40. The connecting portion 23 is interposed between the portion 21 and the body 30. The cavity 24 opens on the proximal side of the head 20. The cavity 24 is designed to receive a tool, for example a Phillips screwdriver, to disassemble the panel 2 of the support 3. The assembly of the clip 10 can be achieved by simple manual pressure on the head 20 or the panel 2 itself, as detailed below. The tool is only useful for disassembly. Each stop member 25 comprises a radial portion 26 and two longitudinal abutment members 27. The radial portion 26 partially forms a ring around the main portion 21, radially to the axis X10. More specifically, the annular portion 26 extends at 120 degrees around the axis X10. Alternatively, the annular portion 26 may extend between 115 and 135 degrees about the axis X10. This angle between the abutment members 27 depends in particular on the angle of rotation of the helix 32.
    [0009] The radial portion 26 is located on the distal side of the main portion 21, bordering the connecting portion 23. The stop members 27 extend along the main portion 21, parallel to the axis X1, from the edge of the connecting part 23 and the ends of the radial portion 26. The stop elements 27 stop approximately halfway up the main part 21, without reaching the flange 22. Between the radial portion 26 and the stop elements 27, each stop member 25 delimits a housing for receiving a complementary abutment element 47 belonging to the base 40. As shown in particular in FIGS. 4 to 10, the body 30 has an outer profile in the form of a helix 32. The helix 32 is tapered on either side of an inflexion plane P32 transverse to the central axis X10. In other words, the helix 32 has a maximum width in the plane of inflexion P32 and its width decreases away from this plane P32. In the example of the figures, the plane P32 is perpendicular to the axis X10. The angle of rotation of the helix 32 about the axis X10 can be between 35 and 55 degrees. Around the axis X10, the helix 32 comprises two reliefs 33 and two recesses 34 interposed between the reliefs 33. The reliefs 33 and the recesses 34 are opposed in pairs, radially to the axis X10. At the junction between each relief 33 and each recess 34, the propeller 32 has an edge or edge 35 provided to slide against the support 3, as detailed below. The helix 32 has a distal end 36 and a proximal end 37, each having a convergent shape away from the plane P32. The housing 16 opens out from the core 12 into the cavity 24 and at the distal end 36, as shown in FIG. 6. The body 30 also comprises two diametrically opposed grooves 38, which are formed in the reliefs 33 and open on the outside. outside the body 38. Each groove 38 has an annular shape and is designed to receive a lug 68 formed on one of the arms 60. The groove 38 has a recess 39 located at the inflection plane P32.
    [0010] The groove 38 is open at the recess 39 and closed opposite the recess 39. The base 40 comprises a plate 41 having a proximal surface 42 and a distal surface 43. This surface 43 is provided to bear against the surface 2a of the panel 2. The base 40 further comprises an inner cavity 44 of generally cylindrical shape centered on the axis X1. When the clip 10 is assembled, the head 20 is disposed in the cavity 44, being surrounded by the base 40. The base 40 has several hooks 45, 46 and 47, which are elastically deformable and extend in the distal direction from the surface 43. The two hooks 45 are positioned on either side of the arms 60, being oriented outwardly. The two hooks 46 are each positioned next to one of the arms 60, being oriented towards the outside. The two hooks 47 are each positioned next to one of the arms 60, being oriented towards the inside and thus towards the cavity 44. The hooks 46 and 47 are interposed between the arms 60 around the axis X10. In practice, the hooks 45 and 46 make it possible to clip the base 40 on the panel 2 by passing through the orifice 2c. More specifically, the hooks 45 cross the lateral portions 2e of the orifice 2, while the hooks 46 cross the central portion 2d. Thus, the hooks 45 and 46 form axial retention means of the base 40 relative to the support 3. On their part, the hooks 47 form stop elements intended to be received in the stop members 25, and thus cooperate with the stop elements 27 of the head 20. The angle of the helix 32 determines the angle between the abutment members 27, as well as the dimensions and the position of the abutment members 47. The base 40 further comprises two grooves 49 diametrically opposite, formed at the edge of the surface 42 and the cavity 45. Each groove 49 comprises a ramp 49a, a projection 49b and a boss 49c. The grooves 49 are provided to receive the protuberances 29 formed on the flange 22. When the clip 10 is locked, the protuberances 29 are positioned against the ramp 49a. When unlocking the clip 10, the rotation of the tool positioned in the cavity 24 causes the protuberances 29 to slide in the grooves 49, along the ramp 49a to the hump 49c via the projection 49b. This causes the core 12 to rise up along the vertical axis X10, then to hold the core 12 in the unlocked position for the time necessary to dismount the panel 2 with respect to the support 3. The bar 50 has a cross shape with four branches 51 , in section in a plane perpendicular to the axis X10. The bar 50 extends along the axis X10 between a proximal end 52 near the base 40 and a distal end 54 remote from the base 40. The bar 50 is housed in the core 12, more precisely in the housing 16 provided for in FIG. this effect. The bar 50 is thus housed in the body 30 and partly in the head 20 of the core 12. As shown in Figure 10, the housing 16 also has a cross shape with four branches 17, in section in a plane perpendicular to the X10 axis. In other words, the core 12 and the torsion bar 50 comprise complementary means 17 and 51 for fastening in rotation around the central axis X10. In practice, the bar 50 may be elastically deformed during a rotation R1 or R2 of the core 12 about the axis X10. The arms 60 extend on either side of the bar 50, connecting the base 40 and the bar 50. Each arm 60 extends between a proximal end 62 connected to the plate 41 of the base 40 and one end. distal end 64 connected to the distal end 54 of the bar 50. On the side of their ends 64, the arms 60 flex and meet at a portion 66 secured to the end 54. Each arm 60 extends generally according to the longitudinal direction of the staple 10, parallel to the axis X10, except the end side 64. Each arm 60 has a lug 68 formed on the inner side and adapted to be received in a groove 38 of the body 30. The method of implementation of the staple 10 is detailed below.
    [0011] The method comprises a preparatory phase a), of bringing the panel 2 and the support 3. Generally, the support 3 is fixed, while the panel 2 is movable and manipulated by an operator. The panel 2 and the support 3 each comprise an orifice, respectively 2c and 3c, for receiving the staple 10. At this stage, the core 12 and the cage 14 of the staple 10 are assembled.
    [0012] According to a first embodiment a1) of the preparatory phase a), the clip 10 can be positioned on the panel 2 before bringing the panel 2 and the support 3 closer together. The clip 10 is inserted into the hole 2c of the panel 2, usually by the automotive supplier who manufactures the panel 2. The equipment supplier then delivers the panel 2, with clips 10 pre-positioned, on the car assembly line.
    [0013] According to a second embodiment a2) of the preparatory phase a), the staple 10 can be positioned on the panel 2 and the support 3, being introduced through the orifices 2c and 3c, after the approaching of the panel 2 and the 3. The method then comprises an attachment phase b), gradually introducing the clip 10 through the hole 3c of the support 3, until the clip 10 reaches a locking position. This fixing phase b) comprising successive steps detailed below. In a first step b1), while the core 12 and the cage 14 pass through the hole 3c of the support 3, the reliefs 33 and the edges 35 of the propeller 32 slide against the edges of the orifice 3c. A torsion torque is created between the support 3 and the body 30.
    [0014] The propeller 32 is progressively rotated in contact with the support 3, in a first direction R1 of rotation around the axis X10, shown in FIG. 1. At the same time, the torsion bar 50 is elastically deformed around the axis X10, under the action of complementary means 17 and 51 for rotationally securing the core 12 and the bar 50 about the axis X10. The rotation of the core 12 causes a twisting of the bar 50. As the base 40 and the arms 60 of the cage 14 are generally stiffer than the torsion bar 50, only this bar 50 twist. At the same time, the abutment members 25 pivot relative to the hooks 47, the prominences 29 slide in the grooves 49, and the grooves 38 pivot relative to the lugs 68. The abutment elements 27 and 47 complementary limit the relative rotation between the head 20 and the base 40. The flange 22, the stop members 25 and the hooks 47, and to a lesser extent the grooves 38 and the lugs 68, form axial retention means of the core 12 relative to the cage 14. In a second step b2), once the plane of inflexion P32 of the propeller 32 has passed through the orifice 3c of the support 3, the stress exerted on the body 30 by the support 3 is suddenly released. A force return takes place and the torsion bar 50 is elastically deformed until it returns to its initial configuration, while driving the core around the axis X10 in a second direction R2 of rotation opposite to the first direction R1, as shown in figure 1. The return of force is ensured by the tapered shape of the propeller 32.
    [0015] The clip 10 is then in the locked position, so that the panel 2 is rigidly fixed to the support 3. The shape of the propeller 32 prevents accidental removal of the clip 10 from the support 3. The clip 10 is clipped on the panel 2 with the hooks 45 and 46. The surface 43 of the plate 41 is positioned against the surface 2a of the panel 2. In order to disassemble the clip 10, a tool provided for this purpose is introduced into the cavity 24. L The tool drives the core 12 in rotation in the direction R1. The rotation of the head 20 with respect to the base 40 causes the protuberances 29 to slide in the grooves 49, along the ramp 49a to the boss 49c via the projection 49b, so that the core 12 rises according to FIG. vertical axis X10. The rotation and rise of the core 12 make it possible to align the recesses 39 and the lugs 68, because of the operating clearance between the core 12 and the cage 14. The clip 10 is then held in the unlocked position for the time necessary for remove the panel 2 relative to the support 3. In Figures 14 to 18 is shown a clip 10 'according to a second embodiment of the invention. Some constituent elements of the clip 10 'are identical to those of the clip 10 of the first embodiment described above and, for the sake of simplification, bear the same reference numerals. Only the differences between the staples 10 and 10 'are described below for the sake of simplification. The clip 10 'comprises a core 12, a cage 14, a collar 70 and a seal 80.
    [0016] The collar 70 has a base 71 and a lip 72 centered on the axis X10. The lip 72 extends from the base 71 to an end 73. The flange 70 has a frustoconical sectional profile in a plane comprising the axis X10. The flange 70 is fixed to the cage 14 and is provided to bear against the support 3. More specifically, the base 71 is fixed to an anchoring portion 74 formed on the outside of the 40. The end 73 of the lip 72 is provided to bear against the surface 3a of the support 3.
    [0017] The seal 80 comprises a base 81 and two lips 82 centered on the axis X10. Alternatively, the seal 80 may comprise a single lip 82 or more than two lips 82. The base 81 has an annular shape. Each lip 82 extends from the base 81 to an end 83. Each lip 82 has a frustoconical sectional profile in a plane comprising the axis X10. The seal 80 is fixed to the core 12 and placed in abutment against the cage 14. More specifically, the base 81 is fixed to the portion 21 of the head 20. The end 83 of each lip 82 is disposed in abutment against an inner surface of the base 40 defining the cavity 44. Thus, the collar 70 and the seal 80 can improve the seal at the clip 10 '. In variant not shown, the clip 10 'may comprise a flange 70 but no seal 80, or a seal 80 but no flange 70. In FIGS. 19 to 24 is shown a clip 110 according to a third embodiment of FIG. the invention.
    [0018] Some constituent elements of the clip 110 have a similar overall operation, but a different structure, in comparison with the clip 10 of the first embodiment described above, and have the same numerical references increased by 100. Only the differences between the Staples 10 and 110 are hereinafter described for simplification purposes.
    [0019] The clip 110 comprises a core 112 and a cage 114, assembled together by overmolding. The core 112 comprises a head 120 and a body 130. The cage 114 comprises a base 140 and a torsion bar 150, but is devoid of arms. A housing 116 for receiving the bar 150 is delimited in the body 130. The head 120 has portions 121, 122 and 123 of cylindrical shape, and an interior cavity 124 formed through these parts 121, 122 and 123 according to the X10 axis. Two diametrically opposite stop members 127 are attached to the portions 122 and 123 at the portion 121 along the axis X10. A space separates the portion 121 and each of the elements 127 radially to the axis X10. Only one of the elements 127 is shown in Figures 19, 22 and 23.
    [0020] The body 130 has an outer profile in the form of a helix 132, which is tapered on either side of an inflexion plane P132 transverse to the central axis X10. The body 130 is provided with two diametrically opposed orifices 131, connecting the housing 116 to the outside of the body 130. The bar 150 is visible in the body 130 through the orifices 131. The propeller 132 has a distal end 136 and a proximal end 137, each having a convergent shape away from the plane P32. The housing 116 opens out from the core 112 in the cavity 124 but does not open at the distal end 36, as shown in FIG. 20. The base 140 comprises a plate 141 provided with a proximal surface 142 and a surface 143. The base 140 has an interior cavity 144 receiving the head 120. The base 140 has hooks 145 clipping on the panel 2. The base 140 has a hollow block 147 which extends in the distal direction from the surface 143 The cavity 144 is delimited in the plate 141 and the block 147. The block 147 has faces 147a and 147b formed vis-à-vis. The element 127 can abut against the face 147a. In other words, the block 147 forms a complementary abutment element of the element 127. The portion 121 of the head 120 is pivotally mounted around a central cylindrical portion 147c of the block 147. Ribs 149 for stiffening connect the hooks 145 to Block 147. The bar 150 extends between a proximal end 152 and a distal end 154. The bar 150 includes a cylindrical portion 156 on the proximal end 152 side and a cross portion 158 on the proximal end 154 side. The portion 158 has a cross shape with four branches 151, in section in a plane perpendicular to the axis X10. The portion 156 is about two-thirds of the length of the bar 150, while the portion 158 is about one-third of the length of the bar 150 along the axis X10. The housing 116 has a cylindrical proximal portion receiving the portion 156 and a distal portion cross receiving the portion 158 of the bar 150. The distal portion of the housing 116 has a cross shape with four branches 117, in section in a plane perpendicular to the X10 axis. In other words, the core 112 and the torsion bar 150 comprise complementary means 117 and 151 for fastening in rotation about the central axis X10.
    [0021] The operation of the staple 110 is comparable to the operation of the staple 10, described above. The staple 110 is, however, more compact and more resistant to tearing than the staple 10. Moreover, the staple 10, 10 'or 110 may be shaped differently from FIGS. 1 to 24 without departing from the scope of the invention. .
    [0022] As a variant not shown, the complementary means 17 + 51/117 + 151 for securing the core 12/112 and the torsion bar 50/150 in rotation around the central axis X10 may be shaped differently from the figures. For example, the housing 16/116 and the bar 50/150 may have a triangular shape. According to another variant not shown, the clip 10 does not have protrusions 29 and grooves 49. Unlocking the clip 10 is achieved by the action of the tool. The torsion applied by the tool to the torsion bar 50 creates a force for extracting the clip 10 and the panel 2 relative to the support 3. In addition, the technical characteristics of the various embodiments and variants mentioned hereinabove. may be, in whole or for some of them, combined with each other. Thus, the staple can be adapted in terms of cost, compactness and performance.
