    STEERING WHEEL FOR AUTONOMOUS MOTOR VEHICLE.
    FR 3 057 532 - A1 _ Steering wheel (1) for a motor vehicle, comprising a hub (2), a C-shaped portion (3) integral with the hub (2) defining two free ends (3a, 3b) facing l 'from one another, and a complementary arc portion (4) connecting the two free ends (3a, 3b) of the C portion (3), the complementary arc portion (4) defines two opposite ends (4a, 4b) rotatably mounted respectively at said two free ends (3a, 3b) of said C-shaped portion (3) so as to be able to pivot said complementary arc-shaped portion (4) between a first position in which the C-shaped portion (3) and the complementary arc portion (4) define a substantially toroidal convex shape, at a second position in which the complementary arc portion (4) is brought closer to the hub (2).
    Steering wheel for autonomous motor vehicle.
    The invention relates to a steering wheel for an autonomous motor vehicle.
    An autonomous motor vehicle is a vehicle that can roll, steer and adapt to road traffic, without driver intervention.
    When such a motor vehicle operates independently, the passenger installed in the driver's seat remains capable of regaining control of the vehicle. He can in particular regain control of the motor vehicle by actuating the steering wheel.
    However, when he does not wish to control the vehicle, the driver then adopts a resting posture, which differs significantly from his driving posture. In the resting position, the driver is generally more comfortable in the driver's seat. His head then rests on the headrest and his bust is generally lower than when he is driving.
    This is why when the driver of an autonomous motor vehicle is in a resting position, his point of view on the dashboard of the vehicle is modified compared to the driving posture.
    The steering wheel can then partially obstruct the driver's field of vision, in particular when he wishes to read information displayed on the display screen installed behind the steering wheel, which is known by the English term cluster, or close to the lower part of the windshield, in particular with head-up displays, known under the English term of Head-Up Display, more generally abbreviated as HUD.
    To overcome this problem, there is in particular known a retractable steering wheel capable of passing from a driving position, in which the driver can actuate it to steer the vehicle, to a retracted position in which the steering wheel is fully embedded in the dashboard. , so as to free the driver's field of vision.
    However, this type of steering wheel does not ensure optimum safety for the driver, because when the steering wheel is in the retracted position, the driver cannot regain control of the vehicle instantly, for example during a driving situation. emergency.
    There is also known a steering wheel having a C-shaped portion defining two free ends and a complementary arc portion separated into two sub-arcs capable of being retracted by being inserted in translation inside the C-shaped portion, respectively by the two free ends. When the vehicle is in autonomous operation, the driver can then retract the additional arc portion, which corresponds substantially to an upper arc of the steering wheel mounted in the passenger compartment, so that he can read the information displayed on the dashboard at the back of the steering wheel.
    However, such a solution requires a relatively complex mechanical design of the steering wheel so that the arc portion can be inserted and come out in the C portion.
    Also, there is the need for a simpler steering wheel, which can be adapted so as not to obstruct the driver's vision when the latter is in a resting position, while allowing instant recovery.
    To this end, a steering wheel is proposed for a motor vehicle, comprising a hub, a C portion integral with the hub defining two free ends facing each other, and a complementary arc portion connecting the two ends. free of the portion in C.
    The complementary arc portion defines two opposite ends mounted for rotation respectively to said two free ends of said C portion so as to be able to pivot said complementary arc portion between a first position in which the complementary arc portion is spaced from the hub, at a second position in which the complementary arc portion is brought closer to the hub.
    Thus, the steering wheel has a relatively simple structure and makes it possible to retract part of it, in particular when the motor vehicle is operating in driving autonomy. In addition, the fact that the C portion remains deployed, allows the driver to regain control of the vehicle instantly, which allows increased safety during a trip.
    Advantageously and in a nonlimiting manner, the steering wheel comprises for each opposite end a shaft passing through said opposite end and said corresponding free end so as to link in rotation said opposite end and said corresponding free end. Thus the connection is relatively simple to design and inexpensive to produce.
    Advantageously and in a nonlimiting manner, each shaft comprises a fluted cylindrical portion intended to be engaged in a fluted bore formed in said associated opposite end. Thus the shaft can be coupled to the opposite end of the complementary arcuate portion in a relatively robust manner.
    Advantageously and in a nonlimiting manner, the steering wheel also comprises means capable of passing successively from a locked position, preventing the rotation of the complementary portion in an arc relative to the C portion, to an unlocked position, allowing the rotation of the complementary portion in arc relative to the portion in C. Thus, one can avoid an involuntary retraction of the complementary portion in arc as well as an involuntary return of this complementary portion in a driving position.
    Advantageously and in a nonlimiting manner, said blocking means comprise, for at least one shaft, two tongues projecting from said shaft capable of engaging in a groove formed in said associated free end. This provides a relatively robust blocking that is simple to unlock.
    According to an alternative, said blocking means comprise a grooved cylindrical portion of the shaft intended to be engaged in a grooved bore of the C portion. This also makes it possible to obtain a relatively robust blocking and simple to unlock.
    Advantageously and in a nonlimiting manner, the steering wheel comprises return means capable of passing the locking means from the unlocked position to the locked position. Thus, after having performed a rotation of the complementary portion in an arc, the locking means can automatically return to the locked position, allowing simpler manipulation of the steering wheel.
    Advantageously and in a nonlimiting manner, said return means comprise a return spring bearing on said complementary arc portion. Thus, relatively reliable and inexpensive recall means can be obtained.
    Advantageously and in a nonlimiting manner, the flywheel further comprises drive means capable of rotating the complementary portion in an arc relative to the C portion in at least one direction of rotation. In particular the drive means allow the passage of the complementary arc portion from a retracted position to a driving position. Thus, when the driver wishes to regain full control of his vehicle, he can relatively simply and quickly redeploy the steering wheel to a driving position, in which the steering wheel has a substantially toroidal shape.
    Advantageously and in a nonlimiting manner, said drive means comprise a torsion spring secured on the one hand to the C-shaped portion and on the other hand to the complementary arc-shaped portion. Thus the drive means are relatively robust, simple and inexpensive.
    The invention also relates to a motor vehicle comprising a steering wheel as described above.

    - Figure 8 is a schematic view of an alternative embodiment of the invention.
    With reference to FIG. 1, a steering wheel 1 comprises a hub 2, a C-shaped portion 3, also called a C 3 portion, integral with the hub 2, and a complementary arc portion 4.
    The C-shaped portion 3 is secured to the hub by means of spokes 5, here three spokes 5 ’, 5”, 5 ’”. Two spokes 5 ’, 5” are opposite with respect to the hub 2, while the third spoke 5 ’” is oriented substantially perpendicular to the first two spokes 5 ’, 5”.
    The C-shaped portion 3 has two free ends 3a, 3b facing each other.
    The C-shaped portion 3 is made of a metal frame 30, overmolded for example by a polymer material 31. It can also be covered with a trim element for example in leather, imitation leather or any other usual material for covering a steering wheel 1.
    The complementary arc portion 4 has an arc length corresponding substantially to the distance of the two free ends 3a, 3b from the C-shaped portion 3. Thus, the complementary arc portion 4, also called complementary portion 4, can close the C 3 portion so that the assembly defines a substantially toroidal shape.
    The complementary portion 4 is made of a metal frame 40, overmolded for example by a polymeric material 41. It can also be covered with a trim element for example in leather, imitation leather or any other usual material to cover a steering wheel . In particular, the complementary portion is covered with the same packing material as the C 3 portion.
    In this embodiment, the complementary portion 4 comprises a metal frame 40 obtained in one piece.
    The complementary arc portion 4 has two opposite ends 4a, 4b mounted for rotation respectively at the two free ends 3a, 3b of the C portion.
    Thus, in a first position, also called the driving position, the complementary portion 4 is spaced from the hub 2, so that the complementary arc portion 4 and the C portion 3 define a substantially toroidal convex shape.
    For reasons of grip and aesthetics, the assembly 3,4, substantially toroidal, may have flats on its circumference. Depending on the steering wheel, the flats can be installed on the C portion 3 and / or on the additional portion 4.
    The complementary portion 4 is rotatably mounted on the C-shaped portion so that it can pass from the first position, shown in dotted lines in FIG. 1, to a second position, also called the retracted position, in which the complementary portion 4 is close to the hub, shown in solid lines in Figure 1.
    The rotation between the first and the second position may correspond to a rotation of 180 ° or alternatively according to an rotation between 90 ° and 180 °, more particularly between 120 ° and 180 °, for example a rotation of 160 °.
    In an alternative embodiment, an intermediate position corresponding to a rotation of 90 ° or substantially half of the rotation between the first and the second position can be provided.
    The rotation between the first position and the second position is generally carried out so that the complementary portion 4 approaches the dashboard, not shown, before approaching the hub 2. In other words, the rotation takes place towards the front of the motor vehicle.
    However, the rotation can just as easily be carried out towards the rear of the motor vehicle, so that the complementary portion 4 moves away from the dashboard before approaching the hub 2.
    In order to allow the rotation of the complementary portion 4 with respect to the portion at C 3, the steering wheel 1 comprises rotation means 20.
    The rotation means 20 comprise, for each free end 3a, 3b of the portion at C 3, a pivot connection 21 with the corresponding end 4a, 4b of the complementary portion 4.
    The pivot link 21 extends in this embodiment in a direction locally perpendicular to the end faces 23, 24 respectively of the C portion 3 and of the complementary portion 4 opposite Tune of the other.
    However, it is possible to adapt the angle of attachment of the pivot link relative to the ends 3a, 3b of the C portion 3 and of the respective ends 4a, 4b of the complementary portion 4 in order to allow the passage of the complementary portion 4 of the first to the second position.
    In a first embodiment of the invention with reference to Figures 3 and 4, the rotation means 20 comprise for each free end 3b of the portion at C 3, a shaft 32.
    In the following description, only a shaft 32 associated with a free end 3b of the portion at C 3 and an associated end 4b of the complementary portion will be described. The other shaft 32 associated with the other end free 3a of the portion at C 3 and the other associated end 4a of the complementary portion 4 being identical.
    The shaft 32 engages through the C 3 portion, perpendicular to the plane of the end 30b of the frame 30.
    The shaft 32 thus crosses the armature 30 of the C portion 3 through a substantially circular opening 33, and engages in a grooved bore 43 formed in the complementary portion 4 opposite the opening 33 of the portion at C 3.
    Thus, the shaft 32 forms a pivot connection between a free end of the portion at C 3 and the complementary portion 4.
    The steering wheel comprises means for blocking the rotation of the complementary portion 4 relative to the C portion 3.
    Referring to Figure 5, the shaft 32 has a head 54, a grooved cylindrical portion 51 extend from the head 54 and an end portion 53, of radius smaller than the cylindrical toothed portion 51.
    The grooved cylindrical portion 51 has grooves 55 intended to come to engage in complementary grooves 48 formed in a grooved bore 43 of the complementary portion 4.
    Thus, when the splines 55 of the shaft 32 are engaged in the complementary splines 48 of the complementary portion 4, the shaft 32 is coupled in rotation to the complementary portion 4.
    The head 54 comprises a circular body 58 of diameter substantially equal to the grooved cylindrical portion 51, for example obtained in one piece with the grooved cylindrical portion 51, and two tongues 56, 57 extending radially from the circular body 58.
    The two tongues 56, 57 are radially opposite with respect to the circular body 58.
    A first tongue 57 has a thickness, along the axis of the shaft 32, greater than the thickness of the second tongue 56.
    The head 54 is inserted in abutment in the opening 33 of the portion at C 3.
    Referring to Figure 6, the opening 33 has a shoulder 65 on which are installed two cylindrical segments 62, 63 defining a groove 64 extending diametrically relative to the opening 33.
    The groove 64 is dimensioned so that the tongues 57 of the head 54 of the shaft 32 can be inserted therein, and so that the first tongue 57 can come into abutment against the shoulder 65.
    Since the first tongue 57 has a greater thickness than the second tongue 56, when the first tongue 57 abuts against the shoulder 65, the second tongue 56 is kept at a distance from the shoulder 65.
    A return means 35 of the shaft 32, here a return spring 35, is installed in abutment against a face of the grooved bore 43 opposite the face 40b opposite the portion at C 3.
    The return spring 35 is also secured to the end portion 53 of the shaft 32, for example by winding at least one turn around the end portion 53, so that the return spring 35 tends to hold the grooves 55 of the grooved cylindrical portion 51 engaged in the grooved bore 43 of the complementary portion 4.
    A cap 38 is fixed to the end portion 53 opposite the complementary portion 4 relative to the insertion side of the shaft 32.
    Thus, when pressure is exerted on the cap 38 in the axial direction of the shaft 32, the latter is moved so that the tongues 56, 57 come out of the groove 64, while the grooves 55 of the cylindrical grooved portion 51 remain engaged in the grooved bore 43 of the complementary portion 4. This allows the rotation of the complementary portion 4 between the first position and the second position, by a rotation of 180 ° around the axis of the shaft 32.
    When the pressure is released on the cap 38, the return spring 35 exerts a traction on the shaft 32. The tongues 56, 57 engage again in the groove 64 and the first tongue 57 abuts against the shoulder 65, which has the effect of prohibiting the rotation of the complementary portion 4 relative to the portion at C 3.
    A removable cover 34 is mounted on the C-shaped portion 3 so as to close the substantially circular opening 33 through which the shaft 32 passes.
    This removable cover 34 is mounted on the C 3 portion on the side by which the shaft 32 is inserted. Also, this removable cover 34 makes it possible to hide the shaft 32, and when it is removed, to access the shaft 32 for example to assemble and disassemble it.
    Drive means 49 enable the complementary arc portion 4 to rotate relative to the C 3 portion when the complementary arc portion 4 is free to rotate, in particular to allow the complementary arc portion to return 4 from the second position, called the retracted position, to the first position, called the driving position.
    Here the drive means 49 comprise a torsion spring 49 wound around one end of the complementary portion 4 and fixed to the portion at C 3, for example by an end 49b engaged in a notch 44. Thus, when the portion complementary 4 is in the second position, and while pressure is exerted on the cap 38, the torsion spring 49 tends to force the passage of the complementary portion 4 between the second position and the first position.
    In other words, the torsion spring 49a allows automatic return of the complementary portion 4 between the second position and the first position when pressure is applied to the cap 38.
    In this embodiment, pressing on the cap 38 of each of the shafts 32 thus makes it possible to unlock the complementary portion in arc 4 so as to allow it to rotate between the first position, corresponding to the driving position, towards a second position, corresponding to the retracted position.
    When the pressure is released on the cap 38, the return spring 35 pulls the tabs 56, 57 from each shaft 32 towards a locking position. This traction produced by the return spring 35 has the effect of engaging the tongues 56, 57 in the groove 64 when they are aligned with this groove 64, blocking the complementary portion 4 from rotating.
    When the complementary portion 4 is in the second position, or any other position different from the first position, and when the cap 38 is pressed, the torsion spring 49a automatically brings the complementary portion 4 back to the first position.
    According to an alternative not shown, four cylindrical segments can be installed on the shoulder 65, so as to define two distinct grooves, which thus makes it possible to modify and increase the number of locking positions for the complementary portion 4 relative to the C 3 portion, for example in order to obtain possible blocking positions by 90 ° rotation stage.
    According to a second embodiment of the invention with reference to FIG. 7, for each free end of the portion at C 3, the shaft 32 is obtained in one piece with the cap 38, so that the head of the shaft 32 corresponds to the cap 38.
    In this embodiment, the end portion 73 of the shaft is grooved is inserted into a grooved bore 71 of the C portion 3 after this end portion 73 has passed through the opposite end 4b of the portion complementary 4 opposite the corresponding free end 3b of the portion at C 3.
    In other words, the shaft 32 is inserted so that its end portion 73 firstly crosses the opposite end 4b of the complementary portion 4 then the grooved bore 71 of the portion at C 3 so that the head 38 of the shaft 32 comes to bear on the complementary portion 4.
    When the cap 38 undergoes a pressure in the axial direction of the shaft 32, the grooves of the end portion 73 come out of the grooved bore 71 of the C portion 3; the complementary portion 4 then being free to rotate relative to the portion at C 3.
    The return means 35 of the shaft 32 here comprise a return spring 35 installed so that it tends to hold the grooves of the end portion 73 engaged in the grooved bore 71.
    Thus, when the cap 38 is pressed, the complementary portion 4 is released, thus allowing the rotation of the complementary portion 4 relative to the portion at C 3.
    During the rotation of the complementary portion 4, and in the absence of pressure on the cap 38, when the grooves of the grooved bore 71 align with the grooves of the end portion 73, the latter engage therein so as to block the rotation of the complementary portion 4.
    The number of grooves on the grooved bore 71, and therefore on the end portion 73 of the shaft 32 defines the pitch of rotation allowing the blocking of the complementary portion 4.
    For example, four splines provide locking positions in 90 ° rotational steps, while two splines provide locking positions every 180 °.
    Removable covers 76, 77, 78, 79 are mounted in the vicinity of the grooved bore 71, so as to mask the junction between the portion at C 3 and the complementary portion 4.
    Two removable covers 79, 76 are mounted on either side of the end of the complementary portion 4 in the vicinity of the grooved bore 71 while two other removable covers 77, 78 are installed on either side of the end of the C 3 portion in the vicinity of the grooved bore 71.
    Thus these removable covers 76, 77, 78, 79 make it possible to hide the grooved bore 71 as well as the shaft 32 passing through it, while allowing, when they are removed, to access the shaft 32 for example to mount it and disassemble it.
    The cover 79 installed over the cap 38 may have a through opening capable of allowing the passage of the cap 38 through the cover 79, in order to allow access to this cap even when the cover is mounted on the steering wheel.
    According to another alternative, with reference to FIG. 8, the complementary arc portion 4 may have a movable portion 80 able to pivot relative to the end portions 81, 82 of the complementary portion 4, so as to allow the lowering of a part of the complementary portion 4, in particular when it is in the first position. The means for rotating the movable portion 80 relative to the end portions 81, 82 may for example be identical to those described above for the complementary portion 4 relative to the portion at C 3.
