    Suspension member, electromechanical actuator comprising such a suspension member and closing or sun protection installation comprising such a suspension member or such electromechanical actuator
    The invention relates to a suspension member of an electric motor inside a tubular casing of an electromechanical actuator, within a locking or sun protection installation.
    In the field of closing or sun protection installations, it is known to produce an electric actuator by inserting an electric motor, most often of the geared motor type, inside a tubular casing. Such an actuator is intended to be mounted inside a winding tube of a rollable screen, within a closing or sun protection installation.
    Such a screen can be, for example, a blind, a shutter or a grid.
    In operation, an electric motor generates vibrations which can be transmitted to the elements surrounding the electric motor, in particular the tubular casing and / or the winding tube, which generates noise when the closing or sun protection installation is operating. .
    To overcome this problem, it is known from EP-B-1 727 959 to use one or more elastic coupling means to absorb vibrations in a longitudinal direction, while resisting torsion under the effect of a torque, which allows the electric motor to be positioned correctly in relation to its environment. However, this solution is only partially satisfactory because the known suspension members are struggling to meet a double requirement, namely to have a relatively high torsional stiffness, allowing good transmission of torque around the axis of rotation of the motor rotor. electric, and have flexibility in shearing and bending to ensure mechanical decoupling between the motor and its environment, in order to limit the propagation of vibrations from this motor.
    In known elastic coupling means, it is possible to use cylinders made of synthetic materials, in particular polyurethane, to immobilize an engine relative to a casing. These synthetic material cylinders have limited torque transmission capacities. Increasing their stiffness runs the risk of degrading noise filtration performance. In addition, such cylinders of synthetic material are difficult to mass produce and assemble and are the source of significant production defects.
    It is also known to dampen vibrations from the engine by using parts made of viscoelastic material. Viscoelastic materials effectively introduce damping due to the inherent nature of the material. They are likely to creep significantly, which causes problems with the definition of the operating limit switches of an actuator, or even the oscillations of the load bar of a screen. In addition, the vibroacoustic performances of these viscoelastic materials tend to deteriorate over time.
    It is to these problems that the invention intends to respond by proposing a new suspension member which has sufficient rigidity or stiffness in torsion to allow an electric motor in rotation to be secured with a complementary element, while being sufficiently flexible , in particular in shear and / or in bending, to greatly limit the transmission of vibrations, and therefore of noise, from the electric motor to its environment.
    To this end, the invention relates to a suspension member of an electric motor inside a tubular casing of an electromechanical actuator for a closing or sun protection installation, this suspension member being in one piece and s' extending along a longitudinal axis intended to be aligned on an axis of rotation of a rotor of the electric motor. According to the invention, this suspension member comprises several annular plates arranged perpendicular to the longitudinal axis and juxtaposed along this axis, at least one intermediate annular plate, while each intermediate annular plate is connected to each of the two plates which are adjacent to it, by at least three connection bridges.
    Thanks to the invention, the three connection bridges which connect each intermediate annular plate to the adjacent plates make it possible to distribute the torsional forces applied to the suspension member during the transmission of a torque. This gives the suspension member of the invention good torsional stiffness and better distribution of the torque to be transmitted than the coupling means of the prior art. On the other hand, the three connection bridges which are located on each side of each plate constitute support points which allow the plates to deform elastically, which gives the suspension member of the invention flexibility in bending and / or high shear. By bending is meant a deformation by rotation of one end of the suspension member with respect to the other about a direction perpendicular to its longitudinal axis. By shearing is meant a deformation of the suspension member by translation in a direction perpendicular to its longitudinal axis. The structure of the suspension member with annular plates juxtaposed along its longitudinal axis also makes it possible to limit the transmission of vibrations in a direction parallel to this axis.
    The fact of using at least three connection bridges on each side of each annular plate makes it possible to minimize the thickness of these annular plates both in a radial direction and in a direction parallel to the longitudinal axis, which makes it possible to reduce the material cost of the suspension member. The invention makes it possible to obtain the best compromise between the resistance to torque and the stiffness in bending and shearing while also obtaining a part which is easy to produce, notably by injection. The division by three of the torsional forces at each bridge, due to the distribution of these bridges on the periphery of an annular plate, induces shorter plate sections, or branches, which is in principle a disadvantage for bending. However, the design of the branches, for example the fact that they are rectilinear rather than circular, their adapted dimensioning, can largely compensate for this disadvantage.
    Thanks to the structure envisaged for the suspension member of the invention, it can be produced by injection into a material not loaded with glass fibers, that is to say by means of a well-controlled and economical manufacturing process.
    According to advantageous but not compulsory aspects of the invention, such a suspension member can incorporate one or more of the following characteristics, taken in any technically admissible combination:
    - Each connection bridge forms a fulcrum allowing the plates, in particular the plate sections on either side of this fulcrum, to deform when bending and shearing forces are applied to the member suspension.
    - The connection bridges located on a first axial face of an intermediate annular plate are angularly offset, around the longitudinal axis, with respect to the connection bridges located on a second axial face of the same annular plate, opposite to the first face axial.
    - On each axial face of an intermediate annular plate, the connection bridges are regularly distributed around the longitudinal axis.
    - Each axial face of an intermediate annular plate is equipped with three connection bridges distributed at 120 ° around the longitudinal axis, while two connection bridges arranged on the two opposite axial faces of this intermediate annular plate are angularly offset by 60 ° or 180 ° around the longitudinal axis.
    - Each annular plate is formed by a succession of beams, preferably rectilinear, while each connection bridge is arranged at the junction between two adjacent beams according to the circumference of the annular plate.
    - At least some of the beams of an annular plate work in compression when the suspension member undergoes a torsional force around its longitudinal axis, thus allowing the passage of torque.
    - At least one beam of a pair of two adjacent beams works in flexion around a connection bridge, which ensures the flexibility of the suspension member and contains the vibrations inside the suspension member.
    - The suspension member comprises, at a first axial end portion, a securing interface, rotating around the longitudinal axis, with a fixed part of the engine and, at a second portion d axial end opposite the first end portion, a centering and immobilization interface in the tubular casing.
    - The suspension member comprises, at a first axial end portion, a securing interface, in rotation about the longitudinal axis, with an output shaft of the actuator and, at a second end portion opposite the first end portion, a securing interface, rotating around the longitudinal axis, with an output shaft of the electric motor.
    - The intermediate annular plates and the connection bridges are arranged in an intermediate portion of the suspension member located, along the longitudinal axis, between the first end portion and the second end portion.
    According to another aspect, the invention relates to an electromechanical actuator for a closing or sun protection installation, this actuator comprising an electric motor mounted inside a tubular casing. According to the invention, this electric motor is suspended in this tubular casing by means of at least one suspension member as mentioned above. Such an electromechanical actuator is more robust and quieter than those of the state of the art.
    Advantageously, the electric motor is suspended in the tubular casing by means of a first suspension member as mentioned above, which couples in rotation a fixed part of the motor with the tubular casing, and a second member suspension as mentioned above, which rotates an output shaft of the electric motor with an output shaft of the actuator.
    According to yet another aspect of the invention, it relates to a sun protection closing installation which comprises a suspension member as mentioned above and / or an electromechanical actuator as mentioned above.
    The invention will be better understood and other advantages of it will appear more clearly in the light of the following description of two embodiments of a suspension member, of an embodiment of an electric actuator and two embodiments of an installation in accordance with its principle, given solely by way of example and made with reference to the appended drawings in which:

    We first describe, with reference to Figures 1 and 2, two home automation systems h and l 2 according to the invention and each installed in a building B having an opening 1, window or door, equipped with a screen 2 belonging to a blackout device 3, in particular a motorized blind or a motorized shutter.
    The blackout device 3 can be a blind, in particular of canvas, rollable, as shown in FIG. 1, a pleated or slatted blind, in which case the installation h is a solar protection installation, or a shutter, such as shown in Figure 2, or a grid, in which case the installation l 2 is a closing installation.
    In the first embodiment illustrated in FIG. 1, the screen 2 of the concealment device 3 is wound on a winding tube 4 driven by a motorized drive device 5. The screen 2 is movable between a position rolled up, especially high, and a rolled out position, especially low. The concealment device 3 comprises a support 23 for the screen 2, as well as the winding tube 4 for winding the screen 2.
    In known manner, the roller blind of the blackout device 3 comprises a fabric, forming the screen 2 of the roller blind 3. A first end of the screen 2, in this case the upper end of the screen 2 in the assembled configuration of the concealment device 3 in the home automation installation L, is fixed to the winding tube 4. In addition, a second end of the screen 2, in this case the lower end of the screen 2 in the assembled configuration of the concealment device 3 in the home automation installation h, is fixed to a load bar 8, the weight of which exerts a tension on the screen 2. In FIG. 1, the fabric forming the screen 2 is made from a textile material.
    In known manner, the first end of the screen 2 is fixed to the winding tube 4, in particular over the entire length of the winding tube 4, so as to be able to wind and unwind the screen 2 around the winding tube 4.
    In the case of a roller blind, the high rolled up position corresponds to a predetermined high end position, or else when the load bar 8 of the screen 2 is pressed against the support 23 of the screen 2 of the roller blind 3, and the unwound lower position corresponds to a predetermined lower end-of-travel position, or when the load bar 8 of the screen 2 is pressed against a threshold 7 of the opening 1, or still in the complete unfolding of the screen 2. The installation h shown in FIG. 1 does not have a box and the fabric forming the screen 2, wound on the winding tube 4, is visible.
    In the second embodiment illustrated in FIG. 2, the screen 2 belongs to a rolling shutter 3 which comprises an apron comprising horizontal blades hinged to each other, forming the screen 2 of the rolling shutter 3 and guided by two slides side 6. These blades are contiguous when the screen 2 reaches its low unwound position. The upper blade of the screen 2 is hooked to the winding tube 4 by two clips
    10.
    In this case, the high rolled position corresponds to the abutment of an end blade L-shaped end 8 of the deck 2 of the roller shutter 3 against an edge of a box 9 of the roller shutter 3, while the unwound low position corresponds to the pressing of the final end blade 8 of the deck 2 of the roller shutter 3 against a threshold 7 of the opening 1.
    The winding tube 4 is arranged inside the casing 9 of the rolling shutter 3. The deck 2 is wound and unwound around the winding tube 4 and is housed at least partially inside the casing 9 In general, the box 9 is arranged above the opening 1, or even in the upper part of the opening 1. The box 9 is an integral part of the device for holding the screen 2.
    The motorized drive device 5 is controlled by a control unit 40. The control unit 40 can be, for example, a local remote control unit, as visible in FIG. 2, or a central control unit, not shown . The central control unit optionally controls the local control unit, as well as other similar local control units located in building B.
    The central control unit can be in communication with a weather station, inside or outside building B, including in particular one or more sensors which can be configured to determine, for example, a temperature, a brightness, or another wind speed in the case of an outdoor weather station.
    A comparable control unit, not shown, is used in the first embodiment.
    In Figure 2, only a screen support 23 is shown. In practice, the installation 12 preferably comprises a screen support 23 at each end of the winding tube.
    4.
    The motorized drive device 5 is preferably configured to execute the commands for unwinding or winding the screen 2 of the concealment device 3, which can be transmitted, in particular, by a local or central control unit.
    Figure 3 is a longitudinal section of a motorized drive device 5 which can be either that of the installation of Figure 1, or that of the installation of Figure 2. This motorized drive device 5 comprises a electromechanical actuator 12, of tubular type, making it possible to rotate the winding tube 4, so as to unwind or wind up the screen 2 of the concealment device 3. In the mounted state, the electromechanical actuator 12 is inserted in the winding tube 4. For this, the internal diameter d4 of the winding tube 4 is substantially greater than the external diameter D12 of the electromechanical actuator 12, so that the electromechanical actuator 12 can be inserted in the tube d winding 4, during assembly of the concealment device 3.
    According to another embodiment, the electromechanical actuator incorporates a cylindrical electric motor, but it is inserted in a rail of square or rectangular section, open on one side. The actuator housing can then be cylindrical or of square or rectangular section similar to the section of the rail. The actuator then drives a drive shaft on which the display deployment cords are wound.
    The electromechanical actuator 12 comprises an electric motor 16. The electric motor 16 comprises a rotor and a stator not shown and positioned coaxially around an axis of rotation X16, which coincides with the axis of rotation X4 of the tube winding 4 in the mounted configuration of the motorized drive device 5. In practice, the electric motor 16 may be a gear motor which includes a gear unit and a brake not shown but known per se. The output shaft 17 of the electric motor 16 is visible in Figures 3 and 5. It is provided with internal grooves 172 intended to cooperate with external reliefs of a drive shaft of the electric motor 16, coupled to the rotor, of the brake or the reducer. This output shaft 17 is also provided with external splines 174.
    The electromechanical actuator 12 also comprises a casing 18 of tubular shape, with circular section centered on the axis X16. The housing 18 may be metallic or made of a synthetic material. The external diameter D12 of the actuator 12 is, in practice, equal to that of the tubular casing 18.
    The tubular casing 18 is immobilized relative to the support member 23 by means of a head 21 which seals a first end 18A of the casing 18. A bearing 22 interposed between the casing 18 and the winding shaft 4 allows this shaft to rotate around the axis X4, while the actuator 12 remains fixed relative to the support 23.
    Control means of the electromechanical actuator 12, allowing the displacement of the screen 2 of the concealment device 3, comprise at least one electronic control unit 15. This electronic control unit 15 is able to start the engine electric 16 of the electromechanical actuator 12 and, in particular, allow the supply of electric energy to the electric motor 16.
    Thus, the electronic control unit 15 controls, in particular, the electric motor 16, so as to open or close the screen 2, as described above.
    The electronic control unit 15 comprises in particular a module (not shown) for receiving control orders, the control orders being sent by an order transmitter, such as the remote control 40. Preferably, the order reception module control of the electronic control unit 15 is of the wireless type. In particular, this module is configured to receive radio control commands. The command order reception module can also allow the reception of command orders transmitted by wired means.
    The control means of the electromechanical actuator 12 include hardware and / or software means. By way of nonlimiting example, the hardware means can comprise at least one microcontroller.
    Here, the electromechanical actuator 12 comprises an electrical power cable 19 allowing it to be supplied with electrical energy from the sector or from one or more batteries, not shown, through the support 23 and the head 21. Alternatively, or in addition, batteries are integrated inside the casing 18 of the electromagnetic actuator 12.
    The electric motor 16 is suspended inside the casing 17 by means of a first suspension member 100 more particularly visible in FIGS. 4 and 6 to 11 and a second suspension member 200 more particularly visible in FIGS. 5 and 12 at 15.
    The first suspension member 100 is provided to cooperate, on the one hand, with a fixed casing tube 162 of the electric motor 16. This casing tube 162 is integral, in rotation about the axis X16, with the stator of the electric motor 16 The first suspension member 100 is designed to cooperate, on the other hand, with the casing 18.
    The suspension member 100 extends along a longitudinal axis X100 which is superimposed on the axis X16 in the unassembled configuration of the electromechanical actuator 12 in the winding tube 4. The suspension member 100 extends, along the axis X100, between a first end portion 102 and a second end portion 104. The first end portion 102 is of tubular external shape with generally circular section over most of its circumference and has two grooves 105 each provided with an orifice 106 for the passage of a screw 164 for securing the first end portion 102 to the casing tube 162. An interface for securing in rotation the elements 100 and 162 around the axes X16 and X100 is thus created by the orifices 106. This interface can, as a variant, take another form, in particular areas of the elements 100 and 162 intended to be glued to one another.
    On the inside, the first end portion 102 is provided with internal ribs 107, the height of which increases along the axis X100 in the direction of the second end portion 104 and which have the function of mechanically reinforcing the suspension member. 100.
    The second end portion 104 of the suspension member 100 is of circular external shape centered on the axis X100 with a diameter D104 defined in particular in terms of circumferential ribs 108 of the second end portion 104. This diameter D104 is equal to the inner diameter d18 of the casing 18. The geometry of the second end portion 104 has no effect on the operation or the connection of the suspension member. The ribs shown are only the result of removal of material for the production of the suspension organ by injection.
    The second end portion 104 also includes three hollow compartments 109 accessible, radially to the axis X100, from the outside, through slots 1092 and which have the function of forming a reception space for pins, not shown, fixing the suspension member to the casing 18 of the actuator 12.
    Between the end portions 102 and 104, the suspension member 100 comprises an intermediate portion 110 which is formed by a succession of planar annular plates 120. Each annular plate 120 is planar in the sense that it extends along a main plane P120 perpendicular to the X100 axis. Its thickness e120 is measured parallel to the axis X100 and is at least five times less than the maximum dimension of the annular plate measured in the main plane P120
    In practice, and as can be seen more particularly from FIG. 11, an annular plate 120 is made up of six rectilinear branches 121, 122, 123, 124, 125, 126 forming a regular hexagon with rounded corners.
    As is apparent in particular from FIGS. 6, 7, 8 and 10, three types of plate 120 are to be considered. A first end plate 120 2 is attached to the first end portion 102. A second end plate 120 4 is attached to the second end portion 104. The other plates constitute intermediate plates 120, which are each arranged, along the X100 axis, between two other plates 120.
    There are respectively 120A and 120B the two opposite axial faces of an intermediate annular plate 120 ,. An axial face of a plate 120 is a face of this plate which is perpendicular to the axis X100. Considering that the plate 120, visible in FIGS. 8 and 11 is the same, the face 120A of this plate 120 facing the first end portion 102 is visible in FIG. 11, while its face 120B facing the second portion end 104 is visible in FIG. 8.
    Each intermediate plate 120 is connected to the two adjacent plates 120 2 , 120 4 or 120 by three connection bridges 128. Each connection bridge 128 is made up of a quantity of material which connects two adjacent annular plates 120 and which is in one piece with these trays. Indeed, the suspension member 100 is, as a whole, produced in a single piece, so that the connection bridges 128 are, inter alia, one piece with the other parts of the suspension member 100.
    On the side of the axial face 120A, the connection between each intermediate annular plate 120, and the adjacent plate is torsionally rigid around the axis X100 because the torsional forces are distributed around the axis X100 between the three connection bridges 128. In the same way, on the side of the face 120B of each intermediate plate 120 ,, a torsional force is distributed between the three bridges 128.
    In addition, a torsional force T around the axis X100, applied to the suspension member 100 between the end portions 102 and 104, is distributed over the multiple connections made between the annular plates 120, at the bridges connection 128. In the example, the suspension member 100 comprises eleven annular plates 120, including the two end plates 120 2 and 120 4 and nine intermediate plates 120 ,. In practice, the number of intermediate plates can be between 1 and 15, preferably between 5 and 12.
    Thus, the suspension member 100 is rigid in a direction of twist around the axis X100, represented by the arrow T in FIG. 6. Once immobilized in the tubular casing 18, the suspension member 100 can therefore constitute a fixed reference point for the electric motor 16. In other words, the suspension member 100 allows the torque exerted by the motor 16 to be taken up inside the tubular casing 18.
    On the other hand, the structure of the suspension member 100 gives it a relatively high flexibility in a direction of bending perpendicular to the axis X100, represented by the double arrow F in FIG. 6. Indeed, the connection bridges 128 constitute as many support points allowing the plates, in particular the plate sections on either side of the support point, to deform when bending and shearing forces are applied to the suspension member 100. The material of the suspension member 100 does not have to be viscoelastic. It may in particular be polyacetal or polyamide which are materials stable over time and whose properties do not tend to deteriorate. In addition, these materials are relatively inexpensive and make it possible to envisage mass production.
    It is also noted that, in the case of a torsional force T exerted around the axis X100 between the end portions 102 and 104, at least some of the branches 121 to 126 work in compression, that is to say say in a direction in which these beams are resistant. This makes it possible to size the cross sections of each of the branches 121 to 126 in an optimized manner, by reducing their axial thickness e120 and their width £ 120 measured in the plane P120 perpendicular to their length, that is to say in a close direction. in a radial direction to the X100 axis, while maintaining a distance d120, measured parallel to the X100 axis between two adjacent plates 120, which is relatively large, which makes it possible to increase the flexibility in bending or in shearing of the suspension member 100, without reducing its torsional stiffness. In other words, the geometry of the plates 120 makes it possible to maximize the diameter of the member 100, while reducing the traction / compression forces in the branches 121 to 126.
    According to a variant not shown of the invention, the branches 121 to 126 may be in the form of a circular arc, in which case the annular plates 120 are generally circular or oval in shape. The branches 121 and 126 then work on the bends in bending and in compression when the suspension member is subjected to a torsional force T.
    According to an advantageous aspect of the invention, the connection bridges 128 located on one face 120A of an intermediate annular plate 120, are angularly offset from the connection bridges 128 located on its other axial face 120B. In the example, the three connection bridges 128 formed on the face 120A are distributed regularly on this face 120A, at 120 ° around the axis X100, while the same is true for the connection bridges 128 formed on the axial face 120B. The connection bridges 128 arranged on the axial face 120A are formed on three corners of the hexagon different from the corners on which the connection bridges 128 are formed on the axial face 120B. We denote C 12 the corner of a tray 120, between its branches 121 and 122, C 23 the corner of this tray between its branches 123 and 124, C 34 the corner of this tray between its branches 123 and 124, C 45 the corner of this tray between its branches 124 and 125, C 56 the corner of this tray between the branches 125 and 126 and C 61 the corner of this tray between the branches 126 and 121. On the side of the axial face 120A, the bridges of connection 128 are formed at the corners C 61 , C 23 and C 45j while, on the side of the axial face 120B, the connection bridges 128 are formed at the corners C 12 , C 34 and C 56 . We note the angle of angular offset around the axis X100, between two connection bridges 128 located on the same axial face 120A or 120B of an intermediate annular plate 120,. In the example, the angle a is 120 °. We ηοΐθβ the offset angle between two connection bridges located on the two opposite axial faces 120A and 120B. In the example, the angle β can take two values, namely βι = 60 ° θίβ 2 = 180 °.
    This distribution of the connection bridges facilitates the transmission of torque within the suspension member 100.
    In practice, whatever the number of connection bridges 128, the minimum value of the angle β is preferably equal to half the value of the angle a.
    We consider a pair of two adjacent branches or beams, that is to say two branches or beams connected by a corner, at one of the bridges 128. This is for example the case of the branches 121 and 122 which are adjacent at the level of the bridge 128 formed on the face 120B in the corner C 12 . When the member 100 is subjected to a torsional force T, at least one branch or beam of this pair of branches or beams 121 and 122 works in bending around this bridge 128. The same applies in the other pairs of branches or adjacent beams. In other words, the branches 121 to 126 tend to bend under torsional load, around the bridges 128, which gives certain flexibility to the member 100 and allows it, in particular, to contain the vibrations.
    The suspension member 200 is produced on the same principle as the suspension member 100 and also comprises planar annular plates 220 arranged in an intermediate portion 210 of the suspension member 200, this intermediate portion being formed between a first portion end 202 and a second end portion 204 of the suspension member 200 which extends along a longitudinal axis X200.
    The plates 220 are distributed between an end plate 220 2 attached to the first end portion 202, an end plate 220 4 attached to the second end portion 204 and intermediate plates 220, arranged, along the X200 axis, between the end plates 220 2 and 220 4 .
    The intermediate part 210 of the suspension member 200 is analogous to the intermediate part 110 of the suspension member 100, each intermediate annular plate 220, being connected to the adjacent plate by two series of connection bridges 228 which are at least at number three. This allows to obtain the same advantages, in terms of torsional rigidity and flexural flexibility, as with the suspension member 100.
    According to an optional aspect of the invention, the portions 110 and 210 are identical, which is advantageous in terms of manufacturing in particular.
    The first end portion 202 of the suspension member 100 is of hexagonal internal shape and provided with three orifices 206 for the passage of three screws for securing the suspension member 200 with a flange 24. Only one of these screws is visible in Figures 3 and 5, with the reference 266, it being specified that the other two screws are distributed at 120 ° relative to this screw, around the superimposed axes X16 and X200. The flange 24 is itself immobilized on an output shaft 25 of the actuator 12, by means of a screw 26 which is aligned on the axis X16. Thus, the orifices 206 and the internal shape of the end portion 202 constitute an interface for securing the member 200 with the shaft 25, through the flange 24 and the screw 26.
    Alternatively, the first end portion 202 of the suspension member 100 is secured directly to the output shaft 25 of the electromechanical actuator 12. Other forms of rotationally secured that the screws can also be envisaged, by example a cooperation of appropriate forms.
    The shaft 25 is equipped with a lining 27 which cooperates with a wheel 28 immobilized in the winding shaft 4 by cooperation of shapes. The wheel 28 constitutes a torque transmission member between the shaft 25 and the winding tube 4.
    A member 300 for guiding in rotation is immobilized in the casing 18, near its second end 18B opposite its first end 18A. The member 300 forms a bearing which supports the shaft 25 at the end 18B, with the possibility of rotation of the shaft 25 relative to the casing, around the axis X16.
    Furthermore, the end portion 204 of the suspension member 200 is provided with internal splines 230 complementary to the external splines 174 of the shaft 17, which allows the suspension member 200 and the shaft to be joined in rotation 17 of the motor 16. Thus, when the motor 16 is running, the torque available on the output shaft 17 can be transmitted to the shaft 25, and beyond to the winding tube 4, through the member. suspension 200. To do this, it is important that the suspension member 200 has good torsional rigidity in the direction of the arrow T in FIG. 12, which is obtained thanks to the structure of its intermediate portion 210 which includes the plates 220 and the connection bridges 228. Furthermore, the suspension member 200 has good flexibility in bending and shearing, in particular in the direction of the arrow F in FIG. 12, which makes it possible to filter the noises generated at the electric motor 16.
    The properties and variants mentioned above with respect to the first suspension member 100 also apply to the second suspension member 200.
    These two suspension members have, in addition to a flexibility in bending in the direction of the arrows F in FIGS. 6 and 12, a flexibility in compression, in a direction parallel to the axes X100 and X200 represented by the double arrow Co in these figures. This also makes it possible to filter the vibrations coming from the motor 16. This flexibility in compression results from the flexibility of the whole of the compression member in a direction parallel to the axis X100 or X200.
    The number of branches of an annular tray 120 or 220 can be different from six. In this case, the distribution of the connection bridges 128 or 228 is adapted.
    The number of connection bridges 128 or 228 can be greater than or equal to four.
    The invention is shown above in the case where the two suspension members 100 and 200 are arranged inside the tubular casing 18. As a variant, at least one of these suspension elements can be arranged at the exterior of such a housing. Alternatively, an additional suspension member can be arranged outside such a casing.
    According to another variant, a single suspension member 100 or 200 can be used within the actuator 12. The possible other suspension member can then be in accordance with the state of the art.
    The embodiments and variants envisaged above can be combined with one another to generate new embodiments of the invention.
