It is also understood as "dextral" and "sinister" position respectively a position to the right and left of an individual facing the drive mechanism fixed on the internal face of the body structure element.

The same elements throughout the description are indicated by the same reference numerals.

Figure 1 shows a perspective view of the fastening means according to the prior art of a drive mechanism of a wiper device on the inner face of a body structure element. There is thus shown a drive mechanism 1 of a wiper device of a window 2, of the type known per se, the drive mechanism 1 being in the form of a support plate 3 with a d 4 drive adapted to drive the wiper and through an orifice 5 provided in a rear door 6 on which is fixed the drive mechanism 1.

The rear opening 6 of a motor vehicle consists of a body structure element 7 generally formed from a cut and folded sheet and the window 2.

The body structure element 7 bears on its inner front face 7a, which corresponds to the inner face of the rear opening 6, the drive mechanism 1 of a wiper device on the outer surface of the window 2 such as a wiper blade of a type known per se.

According to the prior art and as shown in FIG. 1, the support plate 3 comprises two radial arms 8, the free ends 9 of which have a radial finger 10 capable of being engaged and secured in an orifice 11 of a plate support 12 fixed on the inner face 7a of the body structure element 7.

It is only represented in FIG. 1 a support plate 3 with two radial arms 8, although it is possible to make a support plate 3 with three radial arms 8 in order to allow better fastening of the drive mechanism 1 on the face internal 7a of the body structure element 7 of the rear opening 6.

FIG. 2 represents a partial perspective view of a first embodiment of the fastening means 13 of the mechanism 1 on the inner face 7a of the body structure element 7.

The drive mechanism 1 as shown in FIG. 2 has three radial arms 8, a sinistral radial arm 8a, a median radial arm 8b and a dextral radial arm 8c.

On the free end 9 of each of the three radial arms (8a, 8b, 8c) are provided fixing means (14, 15) of the radial arm (8a, 8b, 8c) on the inner face 7a of the element of cash structure 7.

Two embodiments of the means for fixing the radial arms (8a, 8b, 8c) on the body structure element 7 and constituting the means for fastening a drive mechanism 1, shown in FIG. first embodiment 14 being described in FIGS. 3 and 4 and a second embodiment 15 in FIG.

It is conceivable to make fastening means 13 of a drive mechanism 1, either only from the first embodiment of the means for fixing a radial arm 14, or only from the second embodiment means for fixing a radial arm 15, or from a combination of the two embodiments of the means for fixing a radial arm (14, 15).

The dextral and sinistral radial arms (8a, 8c) are fixed to the body structure element 7 by means of the first embodiment of the fastening means 14 of a radial arm, these fastening means 14 being in the general form of a plug-type cylindrical body 16 and are shown more precisely in FIGS. 3 and 4. The plug-type cylindrical body 16 is composed of three parts:

an upper part 17 in the general form of a so-called "upper disk" 17,

an intermediate portion 18 in the general form of a so-called "intermediate disk" of greater diameter than the disk of the upper part 17, and

a lower part 19 in the general form of a circular base truncated pyramid, whose diameter of the circular base is smaller than the diameter of the intermediate disc 18 but greater than the diameter of the upper disc 17 and whose circular base is in contact with with respect to the lower face 18a of the intermediate disc 18.

The upper and intermediate disks (17, 18) are separated so as to define between them a circular ditch 20, hereinafter referred to as "upper ditch" 20.

Similarly, the separation between the intermediate disk 18 and the base of the lower truncated pyramid defines a ditch 21 called "lower ditch" 21.

Due to the generally cylindrical shape of the plug-type cylindrical body 16, the ditches (20, 21) consequently form intermediate cylindrical portions of the plug-type cylindrical body 16 but of smaller diameter than the diameter of the upper disc 17, the intermediate disk 18 and the circular base of the truncated pyramid 19.

The free end 9 of each radial arm (8a, 8b, 8c) is in the form of two curved teeth 22 defining a circular interior space 23 in which is adapted to engage, due to its complementary shape, the upper ditch 20. In this way, it is possible to secure the plug-type cylindrical bodies 16 on the radial arms (8a, 8b, 8c) so that the pyramidal end 19 is directed towards the inner face 7a of the structural member of the box 7 when attaching the drive mechanism 1.

Furthermore, the upper surface 17a of the upper disc 17 of the plug-type cylindrical body 16 has in its center an inner orifice 16a whose function will be explained later.

Advantageously, the plug-type cylindrical body 16 is made of a slightly deformable semi-rigid material, for example rubber.

FIG. 5 represents a side view of the second embodiment of the means 15 for fixing a radial arm, and as illustrated in FIG. 2, more precisely means for fixing the median radial arm 8b on the element of cash structure 7.

The second means for fixing a radial arm 15 consist of the plug-type cylindrical body 16 according to the first embodiment of the means for fixing a radial arm 14 on which a second plug-type body 24 has been fixed. generally cylindrical shape, by a radial tongue 25 secured to the second plug-type cylindrical body 24, whose free end 26 is fixed on the upper surface 17a of the upper disc 17 of the first plug-type cylindrical body 16. The tongue 25 thus defines a bridge of material between the two plugs (16, 24).

In addition, the second plug-type cylindrical body 24 has at its lower end a circular base truncated pyramid 27 whose diameter is slightly smaller than the diameter of the second plug 24.

A circular ditch 28 between the circular base of the truncated pyramid 27 and the remainder of the second plug-shaped cylindrical body 24 is defined between a main cylindrical body 24a and the truncated pyramid with a circular base 27.

The circular base of the truncated pyramid 27 of the second plug-type cylindrical body 24 is vis-à-vis the lower end 24b of the main body 24a.

FIG. 6 shows a partial front view of the orifices provided in the body structure element 7 adapted to cooperate with the first and second embodiments of the means for fixing a radial arm, as represented in FIG. 5 .

Indeed, since the second embodiment of the fixing means of a radial arm 15 is partially made from the first embodiment of the means for fixing a radial arm 14, Figure 6 also shows the orifices 29 fit to cooperate with the first embodiment of the means for fixing a radial arm 14.

Thus, FIG. 6 presents two orifices (29, 30):

the first orifice 29, called the main orifice 29, is able to cooperate with the first embodiment of the means for fixing a radial arm 15, that is to say with the first plug-type cylindrical body 16,

the second orifice 30 is, for its part, capable of cooperating with the second plug 24 present in the second embodiment of the means for fixing a radial arm 15.

The first port 29 is in the general form of an eight with a loop, called main 29a, of greater diameter than the other loop, called secondary 29b.

The diameter of the main loop 29a is greater than the diameter of the circular base of the truncated pyramid 19 of the first plug 16 but less than the diameter of the intermediate disk 18 of the first plug 16.

The diameter of the secondary loop 29b is smaller than the diameter of the main loop 29a, but also the diameter of the circular base of the truncated pyramid 19 and the intermediate disc 18.

Advantageously, the diameter of the secondary loop 29b is slightly smaller than the diameter of the cylindrical portion forming the lower ditch 21.

When fixing the plug-type cylindrical body 16 on the internal face 7a of the body structure element 7, the user inserts the lower part 19 of the plug-type cylindrical body 16 into the first orifice 29 at its level. main loop 29a.

Because of the difference in diameter, the user can insert only the lower part 19 of the plug-type cylindrical body 16 through the main loop 29a of the first orifice 29, the lower face 18a of the intermediate disk 18 then coming into abutment against the inner face 7a of the body structure element 7.

In order to lock the plug-type cylindrical body 16 in a stationary position, the user translates the plug-type cylindrical body 16 to the secondary loop 29b of the orifice 29 whose diameter is slightly smaller than the diameter defined by the lower circular ditch 21.

Because the first plug 16 is made of a slightly deformable semi-rigid material, compression forces are formed between the lower ditch 21 and the periphery of the secondary loop 29b causing the plug-type cylindrical body 16 to remain in place. in the secondary loop 29b of the first port 29.

The second orifice 30 has a diameter slightly smaller than the diameter of the circular base of the truncated pyramid 27 of the second plug-type cylindrical body 24 and the diameter of the main body 24a of the second plug-type cylindrical body 24.

However, because the second plug 24 is also made of a semi-rigid deformable material and because of the difference in diameter between the circular base of the truncated pyramid 27 and the second orifice 30, it is possible to insert the truncated pyramid lower end 27 of the second plug 24 in the orifice 30 to obtain a locking and locking of the second plug 24 in the second orifice 30.

Thus, to achieve the attachment of the drive mechanism 1 on the inner face 7a of the body structure element 7, due to the presence of three radial arms (8a, 8b, 8c), there are three main orifices 29 on the internal face 7a of the body structure element 7, that is to say in the sheet of the rear opening 6.

The dextral and sinistral radial arms (8a, 8c) have at their free end 9, the plug-type cylindrical body 16 as shown in Figures 3 and 4 according to the first embodiment of the means for fixing a radial arm 14 , while the median radial arm 8b has at its free end the plug-type cylindrical bodies (16, 24) shown in FIG. 5 according to the second embodiment of the means for fixing a radial arm 15.

When attaching the drive mechanism 1 to the body structure element 7, the user must first insert the pyramidal ends 19 of the main plugs 16 into the main loop 29a of the first orifices 29.

The lower faces 18a of the three intermediate discs 18 of the three main caps 16 then come into contact and abut against the internal face 7a of the body structure element 7.

Then, by a rotational movement (in a clockwise direction as illustrated in Figure 2), the user passes the lower ditch 21 of the plug-type cylindrical body 16 in the secondary loop 29b by sliding of the lower face 18a of the intermediate disc 18 on the inner face 7a of the body structure element 7 and obtains, by deformation and creation of compression forces on the lower ditch 21, the blocking of the cylindrical bodies of the plug type 16 on the body structure element 7 in the secondary loop 29b of the main orifices 29. In order to prevent unintentional rotary movement, counterclockwise, from causing the release of the plugs 16 of the main orifices 29, there is provided, at the level of the plug-type cylindrical body 16 of the arm lower 8b, the plug-type cylindrical body 24 whose pyramidal end 27 is adapted to be inserted by deformation in the secondary orifice 30, after the main plug-type cylindrical bodies 16 have been locked in the secondary loops 29b main openings 29.

It is thus formed locking means and locking means (14, 15).

To unlock the fastening means (14, 15) of the radial arms (8a, 8b, 8c), it is necessary to exert a longitudinal traction force on the tongue 25 to obtain the separation of the ditch 28 of the second stopper 24 blocked in the secondary port 30 and then, by a rotational movement, sliding the main plug-type cylindrical bodies 16 of the secondary loop 29b to the main loop 29a.

It is understood that it is within the skill of those skilled in the art to position the first and second orifices (29, 30) according to the length of the radial arms (8a, 8b, 8c), the length of the tongue 25 and the number of radial arms (8a, 8b, 8c).

Similarly, it is within the abilities of those skilled in the art to adapt the diameters of the orifices to the diameter of the plugs (16, 24), in particular to the diameter of the intermediate disc 18, of the cylindrical portion forming the lower ditch 21 and the circular base of the truncated pyramid (19, 27) to thereby allow the plugs (16, 24) to be locked in the orifices (29, 30) by deformation and creation of compressive forces.

FIG. 7 represents a perspective view of an alternative embodiment of the secondary orifices 30 adapted to cooperate with the second embodiment of the means for fixing a radial arm 15.

More specifically, according to this alternative embodiment, the secondary orifice 30, adapted to cooperate with the cylindrical body of secondary plug type 24, is in the general form of an eight, with a main loop 30a and a loop secondary 30b whose diameter is smaller than the diameter of the main loop 30a.

FIG. 8 more precisely illustrates this new embodiment of the secondary orifice 30.

The other elements described in the previous figures remain identical.

According to this new embodiment, the tongue 25 of the secondary plug type cylindrical body 24 is pivotally attached about the longitudinal axis of the main plug-type cylindrical body 16 on the upper surface 17a of its upper disc 17.

In this way, the secondary plug type cylindrical body 24 is adapted to be pivoted about the longitudinal axis of the main plug-type cylindrical body 16.

Thus, after insertion of the plugs 16 into the main loop 29a of the main orifices 29, the user can insert the pyramidal end 27 of the secondary plug-type cylindrical body 24 in the main loop 30a of the secondary orifice 30 without the need for excessive deformation force during the insertion of the pyramidal end 27 of the secondary plug-type cylindrical body 24 into the secondary orifice As is the case with the secondary orifice 30 as described in FIG. 6.

In order to allow locking of the fastening means (14, 15), the user then rotates the cylindrical body of the secondary plug 24 type from the positon in the main loop 30a to the position in the secondary loop 30b where the cylindrical body of type secondary plug 24 is held in place by deformation and creation of compression forces on the ditch 28 of the second plug 24 because the diameter of the ditch 28 is slightly greater than the diameter of the secondary loop 30b of the secondary orifice 30.

It is understood that it is within the skill of those skilled in the art to position the first and second orifices (29, 30) as a function of the length of the radial arms (8a, 8b, 8c), the length of the tongue 25 and the number of radial arms (8a, 8b, 8c).

Similarly, it is within the abilities of those skilled in the art to adapt the diameters of the orifices to the diameter of the plugs (16, 24), in particular to the diameter of the intermediate disc 18, of the cylindrical portion forming the lower ditch 21 and the circular base of the truncated pyramid (19, 27) to thereby allow the plugs (16, 24) to be locked in the orifices (29, 30) by deformation and creation of compressive forces. FIG. 9 is a partial view of the orifices provided on the body structure element able to cooperate with a third embodiment of the means for fixing a radial arm according to the invention.

More specifically, according to this embodiment, there is provided a main orifice 29 with a main loop 29a and a secondary loop 29b, these loops (29a, 29b) being adapted to cooperate with the main plug 16 as previously described.

There is also provided a secondary orifice 31 of substantially rectangular shape.

The main and secondary ports (29, 31) are adapted to cooperate with the third embodiment of the fastening means 32 as illustrated in Figures 10 and 11 respectively in lateral view and three quarters higher.

The fastening means 32 according to this third embodiment are substantially identical to the fastening means according to the second embodiment of the fastening means 15 and as described in FIG. 5, except that the second plug-type cylindrical body 24 is replaced. by a substantially parallelepipedic element 33 having on its free end a pair of folded tabs 34, directed substantially towards the tongue 25 and arranged on two opposite sides of the parallelepipedal element 33, and more precisely on the two widths of the rectangular cross section of the parallelepipedic element 33.

Thus, the parallelepipedal element 33 is in a front view in the general shape of an arrow with a substantially flat tip. The tabs 34 are advantageously inclined relative to the vertical axis defined by the longitudinal axis of the main plug 16, and more precisely by an angle of between 1 and 30 °, and more precisely between 1 and 10 °.

The tabs 34 are also provided with a deformable material, for example of the same type as that used for the main cap 16.

When fixing the plug-type cylindrical body 16 on the internal face 7a of the body structure element 7, the user inserts the lower part 19 of the plug-type cylindrical body 16 into the first orifice 29 at its level. main loop 29a and translates the plug-type cylindrical body 16 towards the secondary loop 29b of the orifice 29 whose diameter is slightly smaller than the diameter defined by the lower circular ditch 21 to allow the blocking of the first plug-type cylindrical body 16, as has been previously described.

In order to prevent unintentional rotational movement, counterclockwise, from causing the plugs 16 of the main ports 29 to be unblocked, it is provided, more precisely at the level of the plug-type cylindrical body 16 of the lower arm 8b, the parallelepipedal element 33 whose free end is adapted to be inserted into the rectangular orifice 31, after the plug-type cylindrical bodies 16 have been locked in the secondary loops 29b of the main orifices 29.

The free ends of the tabs 34 then bear against the outer face 7b of the body structure element 7 and exert a retaining force on this outer face 7b. This insertion of the parallelepipedal element 33 is made possible because the tabs 34 are made of a slightly deformable material and thus allows a locking of the drive mechanism

I on the body structure element 7.

Once the tabs 34 have been inserted into the rectangular orifice 31, and as represented in FIG. 12, because of the vertically oriented and inclined shape of the tabs 34, then the parallelepipedal element 33 can no longer be disengaged from the orifice rectangular secondary 31, unless the user exerts a transverse thrust force on the two tabs 34 so as to attach them against the parallelepipedic element 33, then a longitudinal force to disengage and disinsert the free end of the parallelepipedic element 33 of the orifice 11.

Thus, it is not possible to unlock the parallelepipedic element 33 by exerting a traction force on the tongue 25, as is the case for the second embodiment of the fastening means 15.

Similarly, it is within the abilities of those skilled in the art to adapt the dimensions of the orifices (29, 31) according to the dimensions of the main plug 16 and the parallelepipedal element 33.

FIG. 13 is a partial view of the orifices provided on the body structure element 7 adapted to cooperate with a fourth embodiment of the means 35 for fixing a radial arm according to the invention, shown respectively in side and top view in Figures 14 and 15.

More specifically, the body structure element 7 has a pair of orifices, a main orifice 29, as previously described, with two loops (29a, 29b) and a secondary orifice 36 having a projecting tooth 37 inclined , advantageously at an acute angle, with respect to the planar surface defined by the surface of the body structure element 7.

The secondary orifice 36 is advantageously of square shape, the tooth 37 bearing on one side of the square and more precisely on the side of the square facing the secondary loop 29b of the main orifice 29, the tooth 37 being then directed towards the opposite side of the square so that the tooth 37 is substantially of complementary shape to the interior space defined by the square secondary orifice 36.

It is understood that the secondary orifice 36 may also be rectangular, triangular or any other suitable form.

The third embodiment of the fastening means according to the invention 35 consists of the first plug-type cylindrical body 16 as previously described, comprising, at its intermediate disc 18, an extension of material in the form of a tongue 38, substantially planar, rectangular and having internally at its end an internal orifice 39.

FIG. 16 represents the fourth embodiment of the fixing means 35 fixed to the body structure element 7. Indeed, in order to allow blocking and locking of the fastening means 36, the user must firstly insert the plug-type cylindrical bodies 16 in the main orifices 29 provided on the body structure element 7, as this has been previously described.

Once it has translated the plugs 16 into the secondary loops 29b of the main ports 29, in order to block and lock in this position the drive mechanism 1 and to prevent unintentional movement unblocks the fastening means (14, 36), the tooth 37 is able to engage in the orifice 39 of the tongue 38, the inclination of the tooth 37 being such that the tooth 37 exerts a thrust force opposed to a directed thrusting movement from the secondary loop 29b to the main loop 29a.

It is understood that it is within the skill of those skilled in the art to adapt the size of the tongue 38 as a function of the location of the secondary orifice 36 and the tooth 37, the tooth 37 being able to be of any suitable form.

The tongue 38 is advantageously provided with a greater thickness at its free end relative to the rest of the tongue 38 to thereby allow a greater or lesser inclination height of the tooth 37 and so that it remains confined in the interior space defined by the orifice 39 of the tongue 38.

Alternatively, the tooth 37 may be provided with some of its sides directly connected and attached to the outer surface 7b of the body structure element 7, for example with its two lateral sides directly attached to this surface 7b, thus making it possible to reinforce the internal rigidity of the tooth 37.

FIG. 17 is a partial perspective view of a particular embodiment of the orifices 29 provided on the body structure element 7 adapted to cooperate with the first embodiment of the fastening means 14 of a radial arm, such as than previously described.

More precisely, according to this alternative embodiment of the main orifices 29, there is provided locking means 40 of the main plug 16 in the secondary loop 29b of the main orifices 29.

The locking means 40 are in the form of a pair of teeth 41 provided on the circumference of the main loop 29a at the central portion of the main orifice 29, that is to say at the level of the intermediate portion between the main loop 29a and the secondary loop 29b.

The teeth 41 are slightly inclined relative to the planar surface defined by the surface of the body structure element 7, preferably an angle less than 45 °.

The teeth 41, and as shown more precisely in FIG. 18, are made from the production of a slot in the surface of the sheet of the body structure element 7 and the folding by lifting of a part of the sheet thus split to form an inclined tooth 41 substantially triangular with a sharp edge 42.

In this way, the tooth 41 has a raised end point with a retaining edge formed by the sharp edge 42 able to stall the body cylindrical plug-type 16 when it is translated into the secondary loop 29b of the main orifice 29.

Each tooth 41 consists of a side 41a coinciding with the surface of the body structure element 7, a second side 41b defining the periphery of the main loop 29a and a raised third side 41c and coming from the slot made in the body structure element 7, the connection between the second and the third side (41b, 41c) forming the pointed end of the tooth 41.

The plug-type cylindrical body 16, and more precisely the intermediate disc 18, is advantageously able to slide on the teeth 41 to be locked in the secondary loop 29b.

The cylindrical body of plug type 16 is indeed able to deform slightly, particularly at its intermediate disk 18, to move from the main loop 29a to the secondary loop 29b.

Once in this position, the retaining edges 42 of the teeth 41 prevent the reverse movement from being achieved due to their elevation, the user having to exert a longitudinal force on the teeth

41 to level them to the same level as the planar surface of the body structure element 7 and thus allow the passage of the plug-type cylindrical body 16 of the secondary loop 29b to the main loop 29a.

Advantageously, the teeth 41 are provided for each main orifice 29 of the means for attaching the radial arms (8a, 8b, 8c), it being understood that it is possible to make these locking means 40 only on one or two main orifices 29. FIG. 19 is a partial perspective view of a second particular embodiment of the locking means 43 provided on the orifices 29 of the body structure element 7 adapted to cooperate with the first embodiment of the fastening means 14 of a radial arm, FIG. 20 being an enlarged view of this second embodiment of the locking means 43.

According to this alternative embodiment, the blocking means 43 of the plug-type cylindrical body 16 in the secondary loop 29b consist of a pair of substantially biplanar elevations or projections 44 disposed on the circumference of the main loop 29a at the the central part of the main orifice 29, that is to say at the intermediate portion between the main loop 29a and the secondary loop 29b.

Elevations 44 consist of:

a first triangular plane 45 having a side 45a coinciding with the surface of the body structure element 7, a second side 45b delimiting the periphery of the main loop 29a and a third side 45c, and

a second triangular plane 46 having a side 46a coinciding with the surface of the body structure element 7, a second side 46b delimiting the periphery of the main loop 29a and a third side 46c coinciding with the third side 45c of the first plane triangular 45.

The first and second planes (45, 46) are substantially elevated with respect to the planar surface of the body structure element 7. Advantageously, the first plane 45 has a smaller inclination than the inclination of the second plane 46.

The second plane 46, by its conformation, has a tip formed by the connection between the second and the third side (45b, 45c) substantially directed towards the main loop 29a.

The inclination of the second plane 46 is such that once the cap-like main body 16 slidably enters the secondary loop 29b, this plug is locked in position in the secondary loop 29b and the second plane 46 thus forms means abutting and locking this cap 16 in the secondary loop 29b, unless exerting a significant thrust force to disengage the plug 16 of the secondary loop 29b by deformation.

It is within the skill of those skilled in the art to adapt the number, the dimension, the shape and the inclination of the planes constituting the elevations 44 so as to obtain locking and locking of the plugs 16 in the loop. secondary 29b.

FIG. 21 is a perspective view of a fifth embodiment of the fastening means 41 of a radial arm of the drive mechanism 1.

It is illustrated in FIG. 21 the fastening means 47 according to this fifth embodiment only provided at the level of the attachment of the median radial arm 8b, the other radial arms (8a, 8c) being fixed on the body structure element 7 using the fastening means 14 as previously described, that is to say using only the cylindrical main body of plug type 16. According to this embodiment, the fastening means 47 are made from a plug-type cylindrical body 48, and as illustrated in three perspective views in FIGS. 22 to 24, this plug 48 being able to cooperate with an orifice 49 provided on the body structure element and as illustrated in FIG.

The plug-type cylindrical body 48 is composed of:

an upper part composed of a circular part 50 with a rectangular part 51 contiguous on its periphery, an orifice 52 being provided in the upper part and more precisely extending in the circular and rectangular portions 51 and 51, the orifice 52 is therefore also of circular shape 53 with a rectangular portion 54 contiguous on the periphery of the circular portion 53; an intermediate portion 55 in the form of a disc, and

a lower part 56 in the general form of a truncated pyramid with a circular base, whose diameter of the circular base is less than the diameter of the intermediate disc 55 and whose circular base is opposite the lower face 55a of the intermediate disk 55.

The circular portion 53 of the orifice 52 of the upper part is advantageously provided through the intermediate portion 55 and the lower portion 56 of the plug-type cylindrical body 48.

By cons, the rectangular portion 54 of the orifice 52 passes through the intermediate portion 55 but only partially the lower portion 56, thereby forming an inner cavity 57, substantially parallelepiped in the lower portion 56. The upper and intermediate parts are separated so as to define between them a circular ditch 58, hereinafter referred to as "upper ditch" 58.

Similarly, the separation between the intermediate disk 55 and the base of the lower truncated pyramid 56 defines a ditch 59 called "lower ditch" 59.

It has already been seen that the free end 9 of the median radial arm 8b is in the form of two curved teeth 22.

Thus, to fix the plug 48 on the radial arm 8b, the teeth encircle the circular portion 50 of the upper part and more precisely partially fit into the upper ditch 58.

Stop means 60 in the form of a pair of projecting elements 61, and as shown more precisely in FIG. 26, are provided on the upper surface of the intermediate disk 55 and make it possible to avoid rotation of the plug 48 once it has been locked in the teeth 22, the projecting elements 61 being provided surrounding the rectangular part 51 of the upper part of the plug-type cylindrical body 48.

It is shown in Figure 25 a partial view of the orifice 49 provided on the body structure element 7 adapted to cooperate with the plug 48 according to this new embodiment.

The orifice 49 is thus in the general shape of an eight with a main loop 49a and a secondary loop 49b, the diameter of the main loop 49a being greater than the diameter of the secondary loop 49b.

The secondary loop 49b also has on its periphery a recess of substantially rectangular material 62 and whose function will be explained later.

Once the plug 48 is secured to the teeth 22 of the radial arm 8b, the user partially inserts the plug 48 in the main loop 49a of the orifice 49 until the lower surface 55a of the intermediate disc 55 abuts against the periphery of the main loop 49a, the diameter of the main loop 49a being smaller than the diameter of the intermediate disk 55.

Once this partial insertion has been performed, the user then translates the plug 48 into the secondary loop 49b, the periphery of the secondary loop 49b then being in contact with the periphery of the lower ditch 59, the plug being in the position as shown according to a view greater than Figure 27.

In this position, the rectangular recess 62 of the secondary loop 49b is advantageously arranged in the continuity of the rectangular orifice 54 partially through the plug-type cylindrical body 48.

Thus, once the plug-type cylindrical body 48 fixed in the secondary loop 49b, then the rectangular recess 62 is situated directly between the parallelepipedal cavity 57 of the lower pyramidal portion 56, and more precisely between the circular base of the pyramid 56 and the intermediate disc 55. It is of course within the skill of those skilled in the art to adapt the position and the dimensions of the rectangular recess 62 as a function of the dimensions of the rectangular orifice 51, the position of the plug-type cylindrical body 48 and the its orientation in the radial arm 8b, the size of the radial arm 8b and the orientation of the teeth 22 of the free end of the radial arm 8b.

Figure 28 is a perspective view of the blocking or locking means 63 adapted to cooperate with the fifth embodiment of the fastening means 48 according to the invention.

The locking means 63 are in the form of a pin 64 having a cylindrical main body 65 having at one end a circular transverse plate 66 and around its periphery a bulge of material 67 in the form of a parallelepiped element extending from the circular plate 66 and of length slightly less than the height defined by the cylindrical main body 65.

FIGS. 29 and 30 respectively represent two successive steps during the insertion of the blocking means 63 into the fastening means 48.

It can thus be seen that the material bulge 67 is of complementary shape to the rectangular portion 54 of the orifice 52 of the upper portion 49 of the plug 48 and that the cylindrical body 65 is also of complementary shape to the circular portion 53 of this orifice 52.

Thus, during the insertion of the locking means 63 into the plug 48, the parallelepipedal bulge 67 is housed in the cavity parallelepipedic 57 provided in the lower portion 56 of the plug 48, this bulge 67 also passing through the recess of material 62, thus allowing the locking of the plug 48 in the secondary loop 49b of the body structure element 7.

Once the pin 64 is completely inserted in the orifice 52, then the transverse plate 66 is directly pressed against the upper part of the plug 48.

Advantageously, the pin 64 is made of a plastic material or rubber and is connected to the plug 48, for example using a wire.

FIGS. 31 and 32 are respectively perspective and upper views of a sixth embodiment of the fastening means 68 of a radial arm according to the invention adapted to cooperate with a pair of orifices provided on the structural element checkout 7.

According to this embodiment, there is provided a pair of orifices on the body structure element 7, a first orifice 29 in the general shape of an eight with a main loop 29a and a secondary loop 29b, as well as a secondary orifice 69 in the general form of an oval or an egg.

The cylindrical body of the plug type 16 is of the same type as that previously described in FIGS. 3 and 4, and comprises a tongue or bridge of material 70 in the extension of its intermediate disc.

18, this tab 70 having on its free end a secondary body 71, advantageously of generally elliptical shape in which is inserted a pivoting element 72 consisting of a main body 73 having on its planar upper surface in the same plane as the material bridge 70, a tab 74 adapted to be gripped by the installer of the drive mechanism 1 on the body structure element 7.

The material bridge 70 and the secondary body 71 are made of a deformable material such as rubber while the pivoting member 72 is made of a rigid material.

The secondary body 71 is advantageously of complementary shape to the internal space between the two lateral edges of the oval orifice 69.

Since the main body 73 of the pivotal member 72 is elliptical in shape and the secondary body 71 is made of a deformable material, then the secondary body 71 is also elliptical in shape.

The substantially elliptical secondary body 71 has its major axis substantially equal to the largest dimension between the two edges (69a, 69b) of the oval orifice 69, so that the main body 73 is able to be inserted into the orifice 69 only when the pivoting element 72 is in the position as shown in FIG. 31, namely that the gripping lug 74 is disposed in the extension of the material bridge 70 and coincidental or parallel with the minor axis of the ellipse of the main body 73 and the main body 73 has its major axis parallel to or coincident with the largest dimension between the two lateral edges (69a, 69b) of the oval orifice 69.

In order to allow the attachment of the drive mechanism 1 to the body structure element 7, the user must initially partially insert the plug-type cylindrical body 16 in the loop. main 29a of the main port 29 until the intermediate disc 18 abuts against the periphery of the orifice 29.

By translational movement, it engages the plug-type cylindrical body 16 in the secondary loop 29b, as previously described.

In order to allow locking of the fastening means 68, the secondary body 71 is able to engage in the orifice 69.

In order to block the secondary body 71 in the orifice 69, the user must grasp the tab 74 and rotate it by a 90 ° angle in the opposite direction (see FIG. 32) or the like of the clockwise, in such a way that the largest dimension of the main body of the pivoting element is substantially coincidental with the distance between the two ends or points of the oval orifice 69.

Advantageously, the distance between the two points is slightly smaller than the major axis of the secondary body 73, so as to obtain a blocking and a maintenance by friction and compression of the secondary body 73 in the oval orifice 69.

Figures 33 and 34 are respectively perspective views and side section of a seventh embodiment of the attachment means 75 of a radial arm according to the invention.

According to this embodiment, the fixing means 75 consist of a cylindrical body of plug type 16, and as described above, having at its intermediate disk 18 a locking tab 76 extending generally radially to the longitudinal axis of the plug 16 and whose free end 76a has a ramp-shaped portion 77 which is adapted to bear against a portion 78 of the body structure element 7 also in the form of a ramp.

The body structure element 7 has an opening 79 consisting of a main orifice 80 and a secondary orifice 81.

The main orifice 80 is generally circular and of diameter at least equal to the diameter defined by the circular base of the truncated pyramid 19 while the secondary orifice 81 is of diameter slightly smaller than the diameter defined by the lower ditch 21.

The connection between the main orifice 80 and the secondary orifice 81 is formed by means of a groove 82 of smaller width than the diameter of the main and secondary orifices 80 and 81.

When attaching fixing means 75 to the body structure element 7, the user first inserts the inverted truncated pyramid lower portion 19 of the plug-type cylindrical body 16 into the main orifice 80 and then translate the plug towards the secondary orifice 81 where the lower ditch 21 is found compressed due to the difference in diameter between the lower ditch 21 and the secondary orifice 81.

When the ramp-shaped portion 77 of the fastening tab 76 rests against the portion 78 of the body structure element 7, the fastening tab 76 deforms elastically forwards then, when the cap 16 is partially compressed in the secondary orifice 81, the fixing lug 76 resumes elastically its initial position shown in FIG. 34 in which the ramp-shaped portion 77 is received in the main orifice 80. The radial end edge 77a of the ramp-shaped portion 78 then abuts against the edge opposite the main orifice 80, so as to prevent the plug-type cylindrical body 16 from moving. of the opening 79 according to an involuntary movement of uncoupling.

FIG. 35 is a perspective view of a new embodiment of the fixing means and of their locking means,

Thus, the fastening means 14 of the radial arms 8 on the body structure element 7 consist of the plug-type cylindrical body 16 and as previously described for FIGS. 3 and 4.

Once these cylindrical bodies 16 partially inserted in the main loops 29a orifices 29 and slid into the secondary loops 29b, to prevent unintentional movement dislodges these cylindrical bodies 16 of the secondary loops 29b, there is provided means for locking 83 of the plug-type cylindrical body 16 adapted to be inserted into the main loop 29a.

These locking means 83 are composed of a longitudinal element 84 with, on each of its two ends, a curved transverse element 85.

Advantageously, the longitudinal element 84 is of length slightly greater than the largest free distance of the main loop 29a once the plug-type cylindrical body 16 has been housed in the secondary loop 29b. The longitudinal element 84, and more precisely the curved transverse elements 85, are able, on one side, to bear against the cylindrical body of plug type 16, while on the other side, to bear against the periphery of the the main loop 29a.

In this manner, the plug-type cylindrical body 16 can no longer move from the secondary loop 29b to the main loop 29a once the longitudinal member 84 is inserted into the main loop 29a.
