Definitions
- the field of the invention is that of equipping bays, used in particular in motor vehicles.
- the invention relates to devices for closing a bay provided in a structural element, for example the bodywork of a vehicle or a door of the vehicle, and comprising a sliding mobile part capable of releasing or closing a opening offering a flush appearance, seen from the outside.
- the invention can in particular equip different types of structures, such as cars, camper vans, coaches and buses, minibuses, trucks, vans, boats, caravans, etc.
- these devices are designed so as to present, seen from the outside, a flush or quasi-flush appearance between the bodywork, or more generally the wall or structure, and the fixed part of the device.
- the shutter device (hereinafter called "flush bay”) comprises a fixed part and a movable part relative to this fixed part, or sliding panel.
- the mobile part is connected to the fixed part by functional elements which ensure the required mobility and which are attached to the face of the fixed part facing the interior of the vehicle.
- These functional elements, or rails provide a guiding and holding function for the mobile panel. They are placed on the face facing the interior of the vehicle, sufficiently far from the edges, or the periphery, of the fixed part so that this periphery can be secured directly to the edges of the bay, without that the rails do not interfere. We can thus get rid of the presence of a connecting frame between the edges of the bay and the fixed part.
- This fixed part can be made of one or more elements (placed next to each other in the same plane), for example in glass or polycarbonate.
- flush bay can thus be mounted entirely independently of the vehicle, and attached, from the outside, in the housing defined for this purpose by the bay, or the housing, defined in the bodywork, or more generally in the wall.
- edges of the fixed part are secured, for example using a bead of glue, to the edges of the bay, without any other intermediate connecting element.
- the flush bay presents, seen from the outside, a smooth, flush appearance, due to the fact that no frame is necessary on the contour of the opening formed in the fixed assembly.
- a guide device comprising a first and a second guide rail fixedly mounted on the fixed part (or fixed structure) of the bay, on both sides other side of the opening closed by the movable panel.
- the movable panel is mounted, by means of shuttles, on the rails, to slide for example in a longitudinal direction, in a sliding plane between one (or more) open position and a closed position, in which it closes the opening.
- the mobile panel is moved, depending on the implementation, manually or using a motor.
- the motor typically an electric motor
- the motor is generally distant from the flush bay. More precisely, the motor is mounted on the structure of the vehicle (on a part of the chassis or in the box of a door, for example) and connected to the mobile panel via a transmission means, in order to control the moving the movable panel between a closed position and one or more open positions.
- the transmission means is elongated, which allows the motor to be mounted offset from the flush bay.
- the transmission means can in particular be in the form of a crenellated cable (called push-pull cable), generally housed in a sheath, connected to the electric motor of the motor group so as to pull or push the mobile panel.
- the transmission means can also be in the form of a rack, for example.
- the motor is thus separated and distant from the bay shutter device, and connected to the latter via the transmission means. It is received on a support secured to the structure (for example bodywork or door) of the vehicle.
- the "flush bay" system (including the support and the transmission means) can be constructed and supplied by a first actor, and then assembled and mounted in the vehicle by the manufacturer of said vehicle, who fixes the shutter device to the edges of the bay and fixes the support and the motor it receives to the structure.
- the support must be located at a sufficiently precise position relative to the rest of the shutter device. to ensure the proper transmission of forces from the drive device. If this distance is not respected, the transmission means may lack tension, or on the contrary be too tight, which harms the transmission of forces by the actuating device (i.e. the motor).
- the actuating device i.e. the motor.
- this relatively precise position results in particular from the dimensions of the relatively rigid sheath in which the cable circulates.
- the relative position between the support and the rest of the shutter device is not data which can be controlled by the manufacturer of the shutter device, and the tolerance on this relative position generates a certain play which can be detrimental to the transmission mechanism of the drive device (for example the motor) towards the movable part of the shutter device. This is all the more the case since in practice, the overall clearance can exceed a centimeter in extreme cases.
- the manufacturer is therefore required to modify the position, adjust or move the support on the structure, or to force on the rigid sheath.
- the first approach is complex, and sometimes harmful to good solidarity in the long term.
- the second harms the proper functioning of the shutter device.
- the invention improves the situation.
- the proposed technique makes it possible to resolve at least some of the drawbacks raised by the prior art. More precisely, the proposed technique relates to a device for closing a bay provided in a structure, the closing device comprising a fixed part, in which an opening is defined, and at least one sliding movable panel guided along two guide rails mounted on one face of said fixed part, between a closed position, closing said opening, and at least one open position, at least one of said guide rails guiding in translation a shuttle ensuring the passage of the panel movable from said shutter position to said at least one open position, and vice versa, said shuttle being intended to be connected to a drive device offset from said shuttle and connected to the shuttle via a means of transmission.
- the shutter device comprises a support intended to receive said driving device, the support being intended to be fixed to said structure and comprising two parts: a first part, called plate, intended to be fixed on said structure and receive said drive device, and a second part, called cover, receiving a first portion, called coupling portion, of said transmission means, the cover being mounted on the plate so that the support is capable of assuming at least two states: a free state, in which the cover and the plate are free in translation relative to each other; a blocked state, in which the cover and the plate are stationary relative to each other.
- cover and the plate are adjustable in translation relative to each other in the free state, and fixed in the blocked state.
- the free state makes it possible to adjust the relative position of the drive device (received by the plate) relative to the transmission means (received by the cover), hereinafter called cover/plate translation.
- the cover/plate translation thus authorized makes it possible to compensate for any play in the direction of adjustment, whether induced by the structure or by the drive device (for example a motor).
- This clearance compensation makes it possible to maintain the transmission means at its nominal length, whereby the preloads within the mechanism are limited.
- a transmission means in the form of a belt it can thus be tensioned thanks to the adjustment offered by the support.
- the transmission means can be a cable, and the play compensation makes it possible to keep this cable under tension.
- the blocked state allows the plate and the cover to be fixed, whereby the drive device can transmit forces to the transmission means and, ultimately, to the shuttle.
- This clearance compensation support thus obtained makes it possible to assemble the shutter device as a whole, support included, without losing the cover/plate translation as long as the shutter device is not mounted on the structure ( ie in a vehicle), the cover and the plate being in the free state (or pre-mounted state of the support).
- this adjustment remains, thus allowing the drive device to be mounted on the support and the support on the structure by compensating for any play.
- the cover and the plate are then in the blocked state (or mounted state of the support), and can no longer translate.
- This blocking thus allows the proper transmission of forces from the drive device to the shuttle via the transmission means, making the shutter device operational.
- the cover and the plate can thus be blocked by the mounting of the drive device (for example the motor) when the latter is fixed to the plate.
- the translation between the cover and the plate allows adjustment of the position of the cover parallel to a direction defined by said transmission means, in said device.
- the device can in fact comprise, on the plate, respectively the cover, means for receiving, holding and/or guiding the transmission means, upstream and/or downstream of the coupling zone with the means of training.
- These receiving, holding and/or guiding means each define a reference axis, advantageously parallel to the translation axis.
- the translation axis can be parallel to the axis of the upstream receiving, holding and/or guiding means.
- the translation axis can form a small angle, for example less than 30°, with one of these reference axes.
- said plate and said cover are connected by at least one retaining member formed on one of said parts and movable in an oblong hole formed in the other of said parts, authorizing said translation in said state free.
- the retaining member maintains the assembled support, that is to say that the cover and the plate are mounted one on top of the other in their respective operating positions, modulo the authorized clearance compensation. More precisely, the plate and the cover are held close to each other by the retaining member, without impeding good adjustment in translation thanks to the oblong hole in which the retaining member is movable.
- At least one of said retaining members is a clip engaging with the oblong hole so as to maintain said parts linked to one another without preventing said translation in said free state.
- the retaining member takes the form of a clip, which greatly simplifies the assembly of the cover and the plate. All you have to do is “clip” the cover onto the plate (or vice versa) to mount the support while allowing the cover/plate to move. This clipping can be carried out after having mounted inside the support the elements relating to the transmission between the shuttle and the drive device (in particular the transmission means and any part used to couple it to the drive device).
- said plate receives a toothed wheel driving said transmission means and driven by the drive device, the axis of the toothed wheel passing through an oblong hole formed in said cover so as to allow said translation in said free state.
- the gear receives the output of the drive device (e.g. the shaft of a motor), while remaining movable in the direction of adjustment within the carrier. This thus makes it possible to receive the drive device in translation and to couple it to the transmission means while making it possible to compensate for any play in the direction of adjustment.
- the drive device e.g. the shaft of a motor
- said plate carries at least two barrels projecting from the plate, each passing through an oblong hole formed in said cover so as to guide the cover in translation relative to the plate in said free state.
- the barrels, or fingers allow not only to receive screws to fix the motor on the plate, but also to guide the cover/plate translation thanks to the grip of each finger in the corresponding oblong hole.
- the guidance thus obtained improves the robustness of the support, but also the precision of the clearance compensation in the direction of adjustment, since the guidance eliminates the movement of the plate relative to the cover (and vice versa) in the other directions.
- the dual function of guiding and fixing also allows the support to be more compact.
- the transmission means comprises a cable housed in two sheath portions, the translation of said cover relative to said plate modifying the distance between said sheath portions.
- the cable thus housed in a rigid sheath can transmit very significant forces, because the sheath ensures their good transmission in the direction of transmission.
- At least one of said sheath portions has an end mounted on the cover, respectively on the plate, said end of the sheath portion ending in a flared, trumpet-shaped portion blocked in said cover , respectively said plate, and free in translation relative to said plate, respectively to said cover, in said free state.
- the flared portion (which can for example be in the shape of a funnel or the end of a trumpet, or form a ring, a protrusion or a bulge) offers a simple assembly of the rigid sheath in the cover, without sacrificing for as well as the possibility of adjusting the plate in translation relative to the cover.
- a second sheath portion is mounted symmetrically.
- the plate and the cover are connected by a gripping portion arranged to block the translation of the plate relative to the cover in the blocked state.
- the gripping portion allows, when the support is in the blocked state, to grip the translation. This seizure allows the drive device to transmit significant forces to the transmission means, while allowing greater fineness of adjustment of the relative position between the cover and the plate compared to what would be possible with a single fixed stop.
- the gripping portion is also simpler in design than an adjustable stop.
- the transition from said free state to said blocked state is obtained by applying pressure to said cover against said plate in a direction orthogonal to the adjustment direction, so that the seizing portion causes a seizure of said translation of the plate relative to the cover in the adjustment direction.
- said pressure is applied by said screws.
- said seizing portion comprises locking elements formed on the cover and on the plate, facing each other in the free state and engaging with each other in said state blocked, so as to prevent said translation.
- the blocking elements comprise at least one pair of sets of grooves extending substantially perpendicular to said adjustment direction.
- the ridges offer fine granularity in the choice of possible positions for seizure (compared to coarser shapes). The compensation adjustment for the plate/cover clearance is therefore finer.
- the grooves also provide a seizure capable of resisting significant forces compared to seizure by friction between two flat surfaces.
- the blocking elements comprise at least one set of grooves formed on one of the parts of the support and the other part has a ductile surface, the grooves biting into the ductile surface in said blocked state , so as to prevent said translation.
- the blocking elements comprise textured surfaces, formed on the plate or the cover, the two textured surfaces engaging in said blocked state, so as to prevent said translation.
- the invention also relates to a motor vehicle comprising at least one shutter device like that described above.
- the invention finally relates to a method of assembling this shutter device described above, the method comprising the steps of: receiving a shutter device whose support is in the free state; securing the fixed part of said shutter device to the edges of said bay; securing the plate of said support to said structure; adjusting the position of said cover relative to said support so that said drive means is adequately placed relative to said shuttle; blocking of said support, by moving from said free position to said blocked position.
- the free state corresponds to a pre-assembly state (i.e. the state in which the operator in charge of assembly receives the shutter device) and the blocked state corresponds to an mounted state, in which the shutter device is operational.

- FIG. 15 schematically represents a variant of Figure 14.
- FIG. 1 represents an example of a shutter device 1 according to the invention.
- the shutter device 1 aims to close a bay provided in a structure.
- the structure is typically the body or door of a vehicle.
- the shutter device 1 comprises a fixed part 2 in which an opening is defined.
- the shutter device 1 further comprises at least one sliding movable panel 3 guided along two guide rails 4 mounted on one face of said fixed part 2.
- the movable panel 3 is movable between a closed position, closing said opening , and at least one opening position (partially or totally releasing the opening).
- One of the rails 4 (here, the rail located in the lower part) guides in translation a shuttle 5 ensuring the passage of the movable panel 3 from said closed position to said at least one open position, and vice versa.
- Said shuttle 5 is intended to be connected to a training device (not shown in Figure 1) offset relative to said shuttle 5 and connected to it via a transmission means 6.
- the device The drive is coupled to the transmission means 6 via a support 7, at a coupling portion 60 of the transmission means 6.
- the transmission means 6 comprises a cable 62 housed in two portions of rigid sheath 64, 66.
- the cable 62 is here notched, or provided with a serration (not shown in the figures), intended to come into engagement with a toothed wheel 16, in a coupling zone between guide ends 641, 661 of said sheath portions 64 and 66.
- the support 7 is intended to receive the training device.
- the support 7 is also intended to be fixed to the structure of the vehicle.
- the design of the shutter device 1, as well as its assembly on the structure of the vehicle causes a certain number of plays which, if they are not compensated, can harm the proper functioning if not the integrity of the parts of the mechanism of said shutter device 1.
- the main sources of such play can be the sticking of the rail on the structure, the length of the transmission means 6 and/or the positioning of the support 7 on the structure.
- the drive device comprises an electric motor 8.
- the motor 8 may not be designed and assembled by the manufacturer of the shutter device 1, but by a separate equipment manufacturer. In practice, this clearance can reach a centimeter, which results in very significant overloads which adversely affect the operation and/or durability of the shutter device 1. These overloads can also make the fixing of the support 7 on the structure more difficult. difficult, because it is necessary to force to complete the assembly.
- the support 7 comprises a first part 10, called plate, and a second part 12, called cover.
- the plate 10 is intended to be fixed on the structure and to receive the training device.
- the cover receives a coupling portion 60 of the transmission means 6.
- the plate and the cover are assembled (or secured) to each other so that they can assume a free state and a blocked state.
- the guiding ends 641, 661 of the sheath portions 64 and 66 are received respectively by the plate 10 and the cover 12, using holding means 101, 121, capable of guiding the cable, in the coupling zone , to engage with the toothed wheel 16.
- the holding means are preferably formed so as to define an open angle, for example between 150 and 175°, to ensure a sufficient contact surface with the toothed wheel.
- the plate 10 and the cover 12 are free in translation relative to each other. This translation makes it possible to move the ends 641, 661 of the sheath portions away from or towards each other to ensure optimal positioning of the cable relative to the toothed wheel.
- the translation can be done along the transmission means 6 in one of its directions when it is between the plate and the cover.
- the translation makes it possible to modify the position of the plate (and therefore of the toothed wheel 16) longitudinally relative to the cable.
- this adjustment direction can be substantially parallel to a longitudinal direction defined by said transmission means, at the level of the coupling zone.
- the cable is slightly bent at the coupling portion once received in the cover.
- the longitudinal direction of the cable that is to say the direction of its tangent at a point — varies slightly, and therefore remains significantly close to the direction of adjustment, of the order of a few degrees.
- the angle of curvature of the cable can be higher without compromising the proper functioning of the mechanism, the important thing being that the direction of adjustment of the plate/cover translation allows adjustment of the position of the motor axis, received in the plate , relative to the transmission means housed in the cover, so as to compensate for mounting clearance and reduce internal stresses.
- the plate 10 and the cover 12 are movable over a certain predetermined translation range along this adjustment direction.
- the cover and the plate are adjustable in translation relative to each other in the free state, and fixed relative to each other in the blocked state.
- any play in the adjustment direction can thus be compensated by moving the cover and the plate in the free state.
- an operator responsible for fixing the shutter device and the motor 8 to the structure tilts the support into the blocked state, whereby the motor 8 can transmit forces to the transmission means (here, at cable 62 in the first portion of sheath 64), and therefore to the shuttle 5.
- This clearance compensation makes it possible to maintain the transmission means at its nominal length and to mount the motor efficiently. This limits the preloads within the motor/cable coupling mechanism (i.e. the stresses when the mechanism is not working).
- the motor 8 and the structure sandwich the support 7.
- the motor 8 and the plate 10 sandwich the cover 12.
- the motor 8 blocks the plate 10 and the plate in translation. cover 12, secure thus the adjustment that these two parts confer thanks to this clamping of the parts of the support
- the support 7 here houses a toothed wheel 16, engaged with the cable 62.
- the toothed wheel is arranged between the plate 10 and the cover 12.
- the toothed wheel 16 is intended to receive the output axis of the motor 8, this by which the motor 8 is coupled to the transmission means 6.
- the axis of the toothed wheel 16 passes through an oblong hole 18 formed in said cover 12 so as to allow the translation of the cover 12 in the free state.
- the support 7 may comprise a spring 160 coaxial with the toothed wheel 16.
- the spring makes it possible to press the toothed wheel 16 against the cover 12, so as to hold said toothed wheel 16 in position.
- the plate 10 and the cover 12 are here of generally flat shape, which allows the support 7 to be relatively thin, facilitating its installation in a vehicle.
- the support 7 may comprise at least one gripping portion 20.
- the support 7 comprises three gripping portions 20, arranged on the periphery of the support 7 (two at the corners of the support 7 and one in the middle of one side of the support 7 ).
- Each seizing portion 20 comprises a first seizing part 200 formed on the plate 10 and a second seizing part 202 formed on the cover 12.
- the first seizing parts 200 are arranged on the plate 10 so that each of these first parts either facing one of the second gripping parts 202 when the cover 12 is mounted on the plate 10.
- the gripping portions 20 prevent the translation of the cover 12 in the adjustment direction X.
- each of the seizing portions 20 comprises a pair of sets of grooves (a first set for the first seizing part 200 and a second set for the second seizing part 202).
- the first game and the second game are of complementary shapes.
- the grooves of the sets of grooves are spaced from each other in the adjustment direction visible in Figures 8 to 10), thus blocking the translation of the cover 12 relative to the plate 10 (and vice versa).
- the grooves engage with each other, which makes it possible to switch the cover/plate assembly into the blocked state.
- the cover 12 and the plate 10 are at a certain distance from each other (at least equal to twice the height of the grooves), the grooves no longer block the cover/plate translation, and the support is in the free state.
- the support may include at least one retaining member 30.
- the support 7 comprises as many retaining members 30 as gripping portions 20.
- the retaining members 30 are identical.
- the retaining member 30 retains the plate 10 near the cover 12.
- the retaining member 30 further authorizes the translation of the plate 10 relative to the cover 12 in the adjustment direction.
- the retaining member 30 is formed of an oblong hole 32 and a finger forming a clip 34 engaging in the oblong hole 32 (when the support is assembled).
- the oblong hole 32 is elongated in the adjustment direction 10 and the finger forming a clip 34 belong to the cover 12.
- the clip finger 34 When the clip finger 34 engages in the oblong hole 32, the clip finger 34 is movable in translation in the oblong hole 32 in the direction X (due to the oblong shape in this direction X).
- the clip-forming portion of the clip-forming finger 34 abuts against the surface of the cover 12 most distant from the plate 10, so as to produce the desired retention.
- the combination of several retaining members 30 as described above not only makes it possible to keep the cover 12 close to the plate 10, but also to allow a certain distance between the cover 12 and the plate 10, so that it is possible to translate them. This makes it possible in particular to position the cover 12 and the plate 10 without the gripping portion 20 blocking this positioning.
- the retaining member 30 may comprise two sets of projections, each set of projections comprising parallel projections distributed in the direction X, each projection forming a clip.
- the two sets of projections forming a clip are formed on the plate 10.
- the cover 12 has two flat and parallel edges, as spaced apart as the two sets of projections are. Thus, when the support 7 is assembled, each set of projections engages with one of these edges, said projections then surrounding the two edges of the cover 12 in the manner of claws. This variant also retains the cover 12 near the plate 10, without blocking the translation in the direction X.
- the support 7 may comprise a guide portion 40, typically intended to act as a key during the assembly of the support 7.
- the guide portion 40 is formed of a plurality of pairs each formed of a guide finger 42 and an oblong hole 44.
- the fingers 42 project from the plate 10 and the oblong holes 44 are formed in the cover 12.
- the distribution of the fingers 42 on the plate 10 is similar to the distribution oblong holes 44 on the cover 12, so that when the cover 12 is assembled on the plate 10, each guide finger 42 passes through one of the oblong holes 44.
- Each of the guide fingers 42 (or only some) can include a tapping, intended to receive a screw used to fix the motor 8 on the support 7. This makes it possible to gain in compactness.
- the gripping portions 20 are formed around the guide portions 40. More precisely, the first gripping part 200 and the second gripping part 202 are formed around one of the guide fingers 42 and around its corresponding oblong hole 44, respectively. Again, this saves space.
- the gripping portion 20 comprises a set of grooves or teeth formed on the plate 10 (respectively on the cover 12), and a ductile surface formed on the cover 12 (respectively on the plate 10). In the blocked state, the grooves or teeth bite into the ductile surface, so as to ensure the blocking of the cover in translation and to be able to transmit forces from the motor 8 to the transmission means 6.
- the gripping portion 20 comprises textured surfaces formed on the plate 10 and the cover 12.
- the textured surfaces when the cover 12 and the plate 10, provide sufficient friction to block the translation of the cover 12 relative to to the plate 10, so as to be able to transmit forces from the motor 8 to the transmission means 6.
- the end 641 of the sheath 64 ends in a flared part 640.
- the flared end 640 engages with a groove 642 formed in the cover. The translation between the sheath 64 and the cover 12 is blocked.
- the plate 10 includes a recess 644 facing the groove 642, but longer, so that the end 641 of the sheath, and in particular the flared part 640, can translate relative to the plate 10 (in particular during adjustment ).
- the second portion of sheath 66 houses the end part 68 of the cable 62 not going towards the shuttle.
- the second sheath portion 66 so as to improve the translation guidance of the cable 62 under the action of the motor.
- the second sheath portion 66 also ends here in a flared portion 661 blocked in translation in the plate 10 and movable in translation relative to the cover 12, in a manner similar to the flared portion of the first sheath portion 64 (but with the role of the plate 10 and the cover 12 reversed).
- the second sheath portion 66 thus houses and guides the end portion 68 of the cable 62 at the plate outlet. This makes it possible in particular to prevent this extremal portion 68 from dangling in the support 7.
- the ends 641 and 661 being blocked, or fixed, relative to the cover, respectively to the plate, and movable in the corresponding recess of the plate, respectively of the cover, the translational movement of the cover relative to the plate according to the adjustment direction X makes it possible to vary the distance between the two ends 641 and 661.
- the second sheath portion 66 may be, depending on the embodiments, optional. In the absence of a second sheath portion 66, the end of the cable 62 can be left free, or guided using an alternative means such as a ring.
- the adjustment direction can be substantially parallel to a longitudinal direction defined by said transmission means at the level of the coupling portion.
- the plate (receiving the toothed wheel) can in particular be movable in translation relative to the cover (receiving the cable) along the cable 62. This allows adjustment of the position of the toothed wheel along the cable, so as to be able to finely adjust the tension of the transmission means, as seen previously.
- the plate is here arranged so as to bend the cable 62 at the level of the toothed wheel 16.
- the contact length between the toothed wheel 16 and the cable 62 is increased, as is the number of teeth in engagement.
- the transmissible forces are greater. However, this does not prevent the adjustment mechanism from functioning properly, as seen above.
- the cable can here be notched (which does not appear in the figures), the notches of the cable engaging with the teeth of the toothed wheel 16 to ensure more reliable transmission with greater efforts.
- a means of transmission has been described consisting of a cable housed in a sheath.
- the transmission means can be a belt 106 driven by the motor via a pulley (serrated or not) 116.
- the belt needing to be tensioned between this pulley 116 and another pulley 110 on the mobile panel side of the flush bay (not shown), the compensation of the play by the support 107 is of great interest in this case as well.
- the plate and the cover of the support 107 are movable in an adjustment direction Y substantially parallel to a longitudinal direction of the belt once tensioned, that is to say a straight line 120 passing by the center of rotation of the two pulleys 110 and 116.
- the adjustment direction Y is substantially parallel to the longitudinal direction 122 of one of the portions 120 (or strand) of the belt 106, preferably the most tense portion 120 (ie in tension).
- the transmission means can also be a bicycle brake cable type cable, not shown.
- Figure 13 represents a simplified flowchart of a method of mounting the shutter device.
- This method comprises the following steps: reception E10 of a shutter device whose support is in the free state; securing E20 of the fixed part of said shutter device to the edges of said bay; E30 securing of the plate of said support to said structure; adjustment E40 of the position of said cover relative to said plate so that said drive means is placed adequately relative to said shuttle, corresponding to a position allowing the correct installation of the motor; blocking E50 of said support 7, by passing from said free position to said blocked position.
- the motor 8 is fixed on the plate 10 during blocking E50. More precisely, the fixing of the motor 8 on the plate 10 by screwing causes the blocking E50 of the support 7. This ensures, among other things, that the support 7 is adjusted in a way which generates the least possible prestress while ensuring good transmission of the efforts, since it is the motor 8 which, upon installation, blocks the cover 12 in relation to the plate 10.
