    Technical area
    The present invention relates to an armrest module for a motor vehicle seat and to a motor vehicle seat provided with such an armrest module.
    State of the art
    In the automotive field, there is known a motor vehicle seat comprising a seat and a backrest, the backrest being pivotally mounted relative to the seat about an axis of transverse direction relative to the seat.
    It is known to provide this type of motor vehicle seat with an armrest allowing an occupant of the seat to rest his arm on the armrest.
    Such an armrest generally has a low degree of position adjustment. Most often, the armrest is simply mounted on the backrest, able to pivot about an axis of direction transverse to the seat.
    This simple rotation does not guarantee the comfort of the occupant of the vehicle seat.

    detailed description
    In the following description, identical elements or identical functions bear the same reference sign. For the sake of brevity of this description, these elements are not described in the context of each example, only the differences between these different examples being described in detail.
    FIG. 1 illustrates a seat 1 of a motor vehicle. The seat 1 has a back 2 and a seat 3. The back 2 has a back frame 4. The seat 3 has a seat frame 5. The back frame 4 is mounted substantially in a pivot connection around an axis D, on the seat frame 5. The seat frame 5 can itself be mounted on the floor 6 of the motor vehicle, for example by means of slides 7 of the seat 1. In the species, the seat frame 5 has feet 8 which are received in the rails 7, so that the position of the feet 8 in the rails 7 can be changed by translation in the direction L of normal advance of the motor vehicle. The height of the legs 8 can also be adjustable. Thus, one can adjust the position of the seat 1 relative to the steering wheel (not shown) of the motor vehicle, in a longitudinal direction of the motor vehicle seat corresponding to the direction L of advancement of the motor vehicle in normal operation.
    An articulation device 9 makes it possible here to adjust the inclination of the back frame 4 with respect to the seat frame 5 and to block the inclination of the back frame 4. Such an articulation device 9 is well known to those skilled in the art. Consequently, for the sake of brevity in the present description, this articulation device 9 is not described in more detail here.
    Furthermore, the seat 1 is provided, in FIGS. 1 and 2, with a first example of an armrest module 10.
    Such an armrest module 10 comprises, according to the example of FIGS. 1 and 2, essentially an armrest arm 12 intended to support the arm of an occupant of the seat 1 of a motor vehicle and a device 14 for adjusting the height and of the trim of the armrest arm 12. It will be recalled that the trim - or longitudinal trim of the armrest arm 12 is, by definition, the inclination of a longitudinal axis of the armrest arm 12 with respect to the horizontal. Thus, in other words, the armrest module 10 comprises means for modifying the vertical position of the armrest arm and its inclination, in the plane of FIG. 1, towards the front / towards the rear according to the normal direction F of vehicle advance. In this way, and unlike an armrest of the prior art, it is possible here to have the armrest 12 at different heights and, at each height, to orient it according to different degrees of inclination.
    In these Figures 1 and 2, the device 14 for adjusting the height and the attitude of the armrest 12 essentially comprises a connecting rod 16 rotatably mounted relative to the seat frame 5 of the seat of the motor vehicle 1 around of an axis substantially parallel to a transverse direction T of the seat 1 of a motor vehicle, the connecting rod 16 also being rotatably mounted relative to the armrest arm 12, about an axis substantially parallel to the transverse direction T. This transverse direction T is for example that of a straight line normal to the median plane or of symmetry of the seat, plane containing the direction F of normal advance of the motor vehicle.
    By connecting rod is meant here any rigid mechanical part adapted to connect two other mechanical parts so that these two other mechanical parts are movable relative to one another. A connecting rod may in particular have, or consist of, a portion extending in a main direction of extension, between two ends. A connecting rod preferably has fixed dimensions.
    In the example of Figures 1 and 2, the connecting rod 16 is fixed in the vicinity of a first end 16a, vertically the highest, to the armrest arm 12. At this first end 16a, the connecting rod 16 is rotatably mounted on the armrest 12, around an axis substantially parallel to the transverse direction T. For example, a first pivot 18, of axis parallel to the transverse direction T, is formed between the connecting rod and the armrest 12 at level of this first end 16a of the connecting rod 16, to allow the relative rotation of the connecting rod 16 relative to the armrest arm 12.
    At its second end 16b, opposite the first end 16a and therefore located here vertically the lowest, the connecting rod 16 is fixed to the seat frame 5. Here, at this second end 16b, the connecting rod 16 is rotatable relative to the seat frame 5, around an axis substantially parallel to the transverse direction T. For example, a second pivot 20, with an axis parallel to the transverse direction T, is formed between the connecting rod 16 and the frame seat 5, at this second end 16b of the connecting rod 16, to allow the relative rotation of the connecting rod 16 relative to the seat frame.
    With such an armrest module 10, the attitude and the height of the armrest arm 12 can in particular be adjusted, in particular independently. The connecting rod 16, because it is rotatably mounted relative to the seat frame 4, allows to modify the height of the armrest arm 12, while allowing, because it is fixed to the arm armrest in a rotary manner, to adjust the attitude of the armrest arm 12. The armrest module 10 thus makes it possible to obtain a greater variety of adjustments of the position of the armrest arm 12 than the prior art, allowing thus improving the comfort of the occupant.
    Furthermore, it should be noted that because the armrest module 10 is fixed to the seat frame 5, the attitude of the armrest arm 12 is not influenced by the orientation of the frame file 4, when the latter is modified by the seat occupant.
    The armrest module 10 also comprises, according to the example of FIGS. 1 and 2, a man-machine interface 22. This man-machine interface 22 is for example in the vicinity of the most forward end, in the direction F normal advancement of the motor vehicle, of the armrest arm 12.
    This man-machine interface 22 can in particular include commands:
    - Adjusting the position of the seat 1, in particular the position of the feet 8 in the slides 7, the height of the feet 8, the relative inclination of the back frame 4 relative to the seat frame 5 around the axis D;
    - Adjusting the position of the armrest module 10, especially when the latter is adjusted using controllable actuators;
    - adjustment of any other parameter in the motor vehicle, such as, for example, adjustment of the radio, GPS, position of the exterior mirrors, interior mirror, position of the steering wheel relative to the dashboard;
    - controls such as central locking of doors, triggering of hazard lights;
    - or any other command accessible to those skilled in the art.
    Thus, the improved position adjustment of the armrest module 10 allows the occupant of seat 1 to more easily access these controls and / or adjustments, thereby improving, even more, the comfort of use of the motor vehicle by the occupant of the seat.
    The armrest module 10 has two degrees of position adjustment according to the example illustrated in FIGS. 1 and 2, namely:
    - The angle a of relative rotation of the connecting rod 16 relative to the seat frame 4; and
    - the angle β of relative rotation of the connecting rod 16 relative to the armrest arm 12.
    According to a first embodiment, these two degrees of adjustment can be modified by means of an electrical control, in particular by means of the man-machine interface 22. This is possible, in particular, when the armrest module 10 comprises actuators electrically controlled adapted to modify the two degrees of adjustment a and β. The actuators can in particular be motors, in particular electric motors, jacks, in particular electric or pneumatic jacks, or any other actuator accessible to those skilled in the art.
    In this case, maintaining the rod 16 in relative position relative to the seat frame 5 and relative to the armrest arm 12 can be achieved in different ways accessible to those skilled in the art. In particular, this holding in position can be mechanical, friction or stops in the actuators brought into play to adjust the degrees of adjustment while ensuring this holding in position. Alternatively, this maintenance can be carried out using electric actuators. In particular, an electromagnet can selectively be used to allow or on the contrary prevent one or more, in particular all the degrees of adjustment, from being modified, simultaneously or not.
    Alternatively, the armrest module 10 includes mechanical actuators adapted to modify the degrees of adjustment. Mechanical actuators are, for example, levers, cogwheels or push buttons. In this case, the rod 16 and the armrest 12 can be held in position mechanically, in the absence of any action by the occupant to modify the degrees of adjustment. In particular, friction or stops can be brought into play in this case. According to another variant, at least one mechanical device for locking in the position of one or more degrees of adjustment can be provided. This can for example be actuated by means of a lever or a push button. Alternatively, at least one electrical device for locking in the position of one or more degrees of adjustment can be provided. This can, if necessary, be ordered using the man-machine interface. The modification of the adjustment degrees can also be carried out manually, by acting directly on the connecting rod 16 and / or the armrest arm 12, once the adjustment degrees are released by the device for blocking these adjustment degrees.
    The example of a seat for a motor vehicle in FIGS. 3 and 4 differs from the example in FIGS. 1 and 2 essentially by the shape taken by the device 14 for adjusting the height and the attitude of the armrest arm 12 of the armrest module 100. Here, in fact, these essentially comprise a pin 24 received in a guide rail 26 for guiding, here for guiding in translation, fixed on the back frame 4, the arm arm 12 being rotatably mounted with respect to the pin 24 about an axis substantially parallel to the transverse direction T.
    By pin is meant here any mechanical part that can be received in the guide rail 26, capable of being moved by translation in the direction of extension of the guide rail 26 and in rotation about an axis perpendicular to the direction of translation, the optionally.
    Thus, the translation of the pin 24 in the guide rail 26 makes it possible to essentially adjust the height of the armrest arm, while the rotation of the armrest arm makes it possible to adjust the attitude of the latter.
    Alternatively or additionally, the pin 24 is formed by the armrest arm 12 and is received in the guide rail 26 so as to allow translation of the pin 24 in the guide rail 26, on the one hand, as well as a rotation about an axis parallel to the transverse direction T of the seat of the motor vehicle 1, on the other hand. In this case, the pin 24 can be rigidly fixed to the armrest arm 12, in particular, the pin 24 can be formed by the armrest arm 12
    Furthermore, to further increase the variety of possible adjustments of the armrest module 100, it has, according to the example of FIGS. 3 and 4, an armrest arm 12 of adjustable length X. To do this, here, the armrest 12 has a first member 28 and a second member 30, such that the second member 30 is capable of being translated relative to the first member 28, preferably in a longitudinal direction of the arm d armrest 12 corresponding, more preferably, to the direction F of normal advance of the motor vehicle. For example, the first part 28 can form a guide rail receiving part of the second member 30 so that, preferably, the second member 30 can only translate relative to the first member 28. The first and second members 28, 30 then form a slide. Alternatively the first and second members 28, 30 can be telescopic.
    In the case of FIGS. 3 and 4 where the armrest arm 12 is of adjustable length X, it is advantageous for the man-machine interface 22 to be in the vicinity of the most forward end of the second member 22 of the arm d armrest 12, in the direction of direction F normal for advancement. This in fact facilitates access for the occupant of seat 1, having adjusted the length X of the armrest.
    In this case again, the length X of the armrest forms a third degree of adjustment, with the relative position p of the pin 24 in the rail 26 and the angle γ between the guide rail 26 and the armrest 12 The modification of these degrees of adjustment X, γ and p and their maintenance, once the desired adjustments have been made by the occupant of the vehicle seat 1, can be carried out as described above in the context of the first example of a seat. motor vehicle described with reference to FIGS. 1 and 2.
    Figures 5 and 6 illustrate a third example of a motor vehicle seat provided with a third example 200 of armrest module.
    This third armrest module 200 differs from the first two examples 10, 100 also by the shape taken by the device 14 for adjusting the height and the attitude of the armrest arm 12.
    Here, in fact, this device 14 for adjusting the height and the attitude of the armrest 12 essentially comprises a first slide 32 and a second slide 34, the first slide 32 being located closer to the rear of the seat. 1 as the second slide 34, in the normal direction F of the motor vehicle. The first and second slides 32, 34 are fixed at a respective end to the seat frame 5. Thus, the first and second slides 32, 34 cannot move, in particular pivot about a transverse axis, with respect to the seat frame
    5. The first and second slides 32, 34 are preferably parallel. The first and second slides 32, 34 can extend substantially vertically as illustrated in FIGS. 5 and 6. However, according to a variant not illustrated, the first and second slides 32, 34 do not extend in a vertical direction but, on the contrary, form a non-zero angle relative to a vertical direction. However, in order to be able to adjust the height of the armrest arm 12, it is preferred that the first and second slides 32, 34 form an angle less than 90 ° with the vertical. More preferably, so that the adjustment of the height of the armrest arm 12 is not accompanied by too great a displacement in the direction F of normal advance of the motor vehicle, the angle formed by the first and second slides 32, 34 with the vertical is less than 45 °, better, less than 30 °.
    Furthermore, the armrest arm 12 is mounted to pivot freely relative to the first slide 32, about an axis substantially parallel to the transverse direction T. This can in particular be achieved by forming a free pivot 36 between the arm of armrest 12 and the first slide 32, in particular between the arm arm 12 and the end of the first slide 32, opposite the end of the first slide fixed 32 to the seat frame 5.
    It should be noted here that the pivot connection between the first slide 32 and the armrest arm 12 is free. It is not necessary to have a device making it possible to specifically adjust, that is to say directly, this rotation of the armrest arm 12 relative to the first slide 32. In fact, this rotation is in fact controlled indirectly by lengthening the first 32 and second 34 slides.
    Furthermore, the armrest 12 is also connected to the second slide 34 so as to allow the armrest 12 to pivot relative to the first slide 34, while maintaining contact between the end of the second slide 34, opposite the end of the second slide 34 fixed to the seat frame 5, and the armrest arm. To do this, one can for example form an annular linear connection between the armrest arm 12 and the second slide 34. In practice, the armrest 12 can be received in contact on the end of the second slide 34 which is not fixed to the seat frame 5. As a variant, this end 34a of the second slide 34 which is not fixed to the seat frame 5 can be received in a housing 35 of substantially cylindrical shape , formed in the armrest arm 12, the housing 35 being of oblong cross section, as illustrated in FIG. 7. Thus, the end 34a of the second slide 34 is in abutment on the bottom of the housing 35, and the shape oblong section of this housing 35 allows rotation of the armrest 12, while ensuring better mechanical strength of the assembly, compared to the case of a simple support of the armrest 12 on the end of the second slide 34, because the weight of the armrest.
    In this third example, the degrees of adjustment can in particular be: the length f1 of the first slide; the length f2 of the second slide; and the length f of the armrest.
    As explained above, it is not necessary to directly adjust the angle Θ between the armrest 12 and the first slide 32. This angle Θ is in fact defined by the lengths f 1, f 2 of the two slides 32, 34. Alternatively, one can adjust the length f1, f2 of a single slide and the angle Θ between the armrest 12 and the first slide 32. The other slide, the length of which is not directly adjustable, can then be elastically constrained towards the armrest arm 32 which forms a stop for the extension of this other slide.
    In all cases, the degrees of settings f, fl and f2; f, f 1 and Θ; or f, f2 and Θ can be set and then maintained as explained above in the context of the first example.
    According to a variant not shown, the armrest arm 12 is rotatably fixed on a single slide 32.
    The fourth example in FIGS. 8 and 9 comprises an armrest module 300 essentially having an armrest arm 12 fixed to a slide 38, itself fixed to the seat frame 5. The slide 38 is thus immobile with respect to to the seat frame 5.
    Such an armrest module 300 makes it possible in particular to adjust the height of the armrest arm 12. Here, the slide 38 is unique but it can be implemented more than one slide 38, in particular exactly two slides 38. The slide 38 extends in the example illustrated in a substantially vertical direction. Alternatively, however, the slide 38 does not extend in a vertical direction. Preferably, however, the slide 38 forms an angle of less than 90 ° with the vertical direction. In particular, to limit the movement of the armrest arm 12 in the event of its height being adjusted, the angle between the longitudinal direction of the slide 38 and a vertical direction is less than 45 °, better still, less than 30 °.
    The length II of the slide 38 allows in this example to adjust the height of the armrest 12.
    Furthermore, in the example illustrated, the armrest arm 12 is of adjustable length. Alternatively, however, the armrest 12 may be of fixed and fixed length.
    Also, in the example of FIGS. 8 and 9, the slide 38 is fixed on the seat frame 5. However, the slide 38 can, according to a variant, be fixed on the back frame 4.
    The adjustment of the length Xl of the slide 38 in the example of FIGS. 8 and 9 can be carried out as explained above in the context of the adjustment of the different degrees of adjustment of the previous examples.
    FIGS. 10a and 10b, on the one hand, and 11a and 11b, on the other hand, however illustrate variants of devices for holding (or locking) in position of the slide 38, which can also be implemented in the examples. previously described.
    In FIG. 10a, a mobile element 40 of the slide 38 has been shown, provided on one of these faces with a plurality of substantially identical notches 42. The notches are for example of cylindrical shape, for example of circular cross section. Here, these notches 42 are spaced apart by a substantially constant pitch. Furthermore, it is illustrated in FIG. 10a a frame 44 which can for example be formed by a housing of the slide 38, in particular a housing in which the movable element 40 of the slide 38 slides. This frame 44 is for example mounted fixed on the seat frame 5 of the motor vehicle seat. This frame 44 forms a housing 46 for receiving a stud 48, of substantially cylindrical shape. The stud 48 here has a substantially cylindrical shape per section. A first section 48a has a diameter substantially equal to the diameter of the notches 42 so that the first section 48a is adapted to be received in the notches 42. The second section 48b is of complementary section to the section of the housing 46 in the frame 44, so that the second section 48b is adapted to be received in this housing 46. The first section 48a is also adapted to be received in the housing 46. On the other hand, the second section 48b is not adapted to be received in the notches 42. For example, the diameter of the second section 48b is greater than the diameter of the first section 48a and the diameter of the notches 42. The stud 48 is elastically constrained, here by a spring 50, so that the first portion 48a of the stud 48 is received in one of the notches 42. This position corresponds to a blocking of the length Xl of the slide 38.
    In FIG. 10b, on the contrary, the locking device is in the unlocked (or unlocked) position allowing the length Xl of the slide 38 to be adjusted. In this unlocked position, the stud 48 is entirely outside the notches 42 of so that the movable element 40 of the slide 38 can be moved relative to the frame 44. To move the stud 48, a force is exerted against the stress force of the spring 50. This force exerted is greater than the force of spring stress 50. This force can in particular be magnetic, mechanical or pneumatic on the stud 48 and / or the spring 50.
    The example of the locking device in Figures 11a and 11b is substantially similar to the example in Figures 10a and 10b. This second example of a locking device differs from the first example described essentially by the shape of the notches 42 and of the first portion 48a of the stud 48. In this second example, in fact, the notches 42 and the first portion 48a of the stud 48 have complementary sections in the shape of rectangular trapezoids. Thus, in section, the notches 42 and the first portion 48a of the stud 48 have:
    a first face 421, 481 substantially perpendicular to the direction of extension of the slide 38 corresponding to the direction of translation of the movable element 40 relative to the frame 44. This first face is preferably, as illustrated in the figures, the upper side; and a second face 422, 482 inclined relative to this direction of extension of the slide 38 corresponding to the direction of translation of the movable element 40 relative to the frame. This second fax machine is preferably, as illustrated in the figures, the underside.
    Thus, when a user places his arm on the armrest arm 12 fixed to the end of the slide 38, the upper face 48i of the stud 48 forms a stop for the upper face 42i of the notch 42 which receives it, as explained above in the context of the example of FIGS. 10 and 10b. Thus, the movable element 40 of the slide 38 is immobilized in downward translation, preventing the armrest 12 from lowering.
    If the user now wants to raise the armrest 12, he can simply pull up on the armrest 12. In this case, in fact, the inclined face 422 of the notch 42 receiving the stud 48 will cooperate with the inclined face 482 of this stud 48 for, under the effect of the movement of the movable element 40 of the slide 38, guide the stud 48 out of the notch 42. The user can thus pull the armrest arm to the next notch 42. When the stud 48 is opposite this next notch 42, in fact, the spring 50 constrains the stud 48 in this next notch 42. The height of the armrest 12 is adjusted by snap-fastening.
    To lower the armrest 12, on the other hand, a device for releasing the movable element 40 is necessary, as in the case of the example in FIGS. 10a and 10b. As explained above, this release device acts on the stud 48 against the constraint of the spring 50 to cause the stud 48 to come out of a notch 42 which received it and, preferably, to maintain this stud 48 in this position out of the notches 42, as long as the release device is actuated. As explained above, this release device can in particular be magnetic, mechanical or pneumatic on the stud 48 and / or the spring 50.
    The present invention is not limited to the single embodiment which has just been described but is on the contrary susceptible of numerous variants accessible to those skilled in the art.
    In particular, the different embodiments can be combined as long as they are not contradictory.
    Also, the fact that the armrest is of adjustable length or, on the contrary, of fixed and fixed length, can be provided in each of the examples presented.
