    [0001] The present invention relates to articulations and angular adjustment devices for a vehicle seat, and particularly to discontinuous seat backrest joints. Such a seat joint is known from document FR2977205. However, in such a device, the spring 10 which advantageously makes it possible to return the control shaft against a stop, away from the locking positions of the control cams in the joints, is arranged outside the articulation itself. even. The present invention is intended, in particular, to improve seat joints, to make them more compact and easier to integrate, while providing good perceived quality and adequate safety features. More specifically, the subject of the invention is a motor vehicle seat joint allowing an angular adjustment of a first armature element with respect to a second armature element around a main articulation axis, comprising the first hinge flange and the second hinge flange, intended to be integrally connected respectively to the first reinforcement element and to the second reinforcement element, a control element able to move locking elements adapted to immobilize. in rotation the first flange of articulation relative to the second flange of articulation, and recalled to a locking position by at least a first spring, 3024080 2 - a control shaft, recalled to a rest position by at least a second spring, - in particular the control shaft is decoupled from the control member and adapted to move in rotation the control member about the axis pr In addition, the control shaft has an external axis on which a handle is mounted, and the control shaft abuts an abutment of the first reinforcement element in the first rest position. For this purpose, the invention proposes a seat hinge characterized in that the second spring is housed between the first and second hinge flanges and bears on the first flange, or fixed flange. By means of which it is possible to reduce the axial dimensions of the articulation and the return of the control shaft, which facilitates the integration of such a mechanism, particularly in the area where the seat is articulated between the back and the seat. Advantageously, it is noted that the return of the control shaft is achieved independently of the return of the control member which ensures the proper re-locking of the joint in the absence of stress on the handle. In various embodiments of the invention, one or more of the following arrangements may also be used. The first spring (s) and the second spring (s) are arranged substantially at the same axial position, so that the axial thickness of such a hinge equipped with such second springs is not thicker than the actual articulation of the prior art. The articulation may comprise at least two first springs, the second spring being arranged halfway circumferentially from the first two springs. The first and second springs can thus alternately be housed in a balanced manner and distributed circumferentially. There are three first springs and three second springs interposed respectively between two first springs, each of the first springs and second springs being separated by an angular difference substantially close to 60 °. It is thus possible to have six return springs, recalling both independently the control member and the control shaft, in particular in six housings or all identical bowls arranged on a disk. The locking elements are guided in translation in the radial direction, under the effect of the rotation of the control member, by guides. In addition, the guides are disposed between the bowls of the springs in the circumferential direction, which makes it possible to optimize the axial compactness of the first armature.
    [0002] An angular clearance is provided between the first rest position of the control shaft and the driving position of the control shaft, forming a dead travel greater than 3 °. Thus, it is ensured that the locking cam is in the locking position of the locking elements. In addition, undesired low amplitude movement on the drive shaft will not lead to undesired release of the hinge.
    [0003] Each of the second springs is formed as a coil spring 3024080, which is an easy solution to industrialize. Further advantageously the second springs may be substantially identical to the first springs, which is advantageous in terms of reducing the industrial diversity. The control shaft may comprise an inner hub and / or a connecting bar.
    [0004] Advantageously, the inner hub comprises at least one radial projection on which the second spring rests to return the control shaft to the first rest position. Thus, a simple solution is proposed for the return of the shaft and the choice of the materials of the parts making up the control shaft is also optimized. An external axis can be clipped on the inner hub. In addition, the link bar can be clipped in the outer axis, which provides axial retention of the link bar. It is thus possible to assemble the mechanism manually without tools. The outer axis may advantageously abut on a stop of the first armature member. In addition, a handle is mounted on the outer axis. This gives a very frank stop, which enhances the quality perceived by the user. The external axis comprises three radial projections, offset at approximately 120 °, which abut against three corresponding abutments of the armature, whereby the forces on the abutment are balanced with respect to the axis, and good sturdiness is ensured. case of significant effort on the handle in the opposite direction to the normal maneuver.
    [0005] The control member comprises a control cam adapted to push the locking elements outwardly in the locked position and a control plate comprising at least one ramp adapted to move the locking elements inwardly in a locked position. unlocked position, whereby one can optimize the choice of materials, for example the metal cam and the plastic control plate, and the weight for the control member.
    [0006] The subject of the invention is also an angular vehicle seat adjusting device comprising a first hinge as described above, the control member of the first hinge forming the first control member, the adjusting device further comprising a second hinge comprising: - third and fourth hinge flanges intended to be integrally bonded respectively to the first and second reinforcement elements, 20 - a second control member adapted to move second locking elements adapted to immobilize the third flange d with the fourth articulation flange, the control shaft being adapted to rotate the second control member about the main axis, wherein the second control member is biased to a locking position by at least a third spring, the first rest position of the arb the control shaft is separated from the position in which the control shaft biases (drives) the second control member from its locking position by a second angular play. So that each of the two joints is attacked by the control shaft after a certain angular stroke.
    [0007] In particular, the first seat member may be a seat seat and the second seat member may be a seat back.
    [0008] The invention also relates to a vehicle seat comprising a seat, a backrest and at least one hinge as described above or an angular adjustment device as defined above.

Furthermore, the first hinge 10 comprises a control member 1 pivotally mounted around the hinge pin Y. The control member 1 is adapted to move the locking member 5 (or locking elements 3024080 when there is has several) between the locked position and the unlocked position. The control member 1 comprises a control plate 12, 5 or control mask 12, and a control cam 11. The control member 1 is resiliently biased by at least first spring 2, preferably several first springs 2, to a locking position in which the control cam 11 pushes the locking element 5 radially outwards in the locked position, as shown in FIG. 5. FIG. 9 is a detailed view showing the control plate 12, or control mask 12, of the control member 1 according to the invention. In the example presented in a nonlimiting manner, the articulation 10 comprises three first springs 2. However, it is not excluded to have two or only one.

Preferably, the first spring 2 is in the form of a spiral spring and comprises, on the one hand, a first end 23, forming an anchorage on a pin 22, in particular semicircular, of the first flange 81, and secondly, a second end 24 slidingly abuts on a pin 25 of the control cam 11.
    [0014] In addition, the first spring 2 is disposed in a housing 94, in particular an individual bowl 94. In the example shown, the housing 94 is interposed between two guides 14 of the locking element 5. Advantageously, the housing 94 is In the example shown, six housings 94 are formed around a central orifice 89 of the first flange 81. The control member 1 can be moved in rotation by the actuation of the first flange 81. from the control handle 95 to an unlocking position, as shown in FIG. 6, where the control plate 12 drives the locking element 5 to move it, preferably radially inwards to the position unlocked.
    [0015] The control plate 12 is in the form of a disk having a central axial opening 92, at least one connecting pin 27, advantageously several connecting pins 27, and at least one peripheral edge 13, advantageously several peripheral edges 13, 15 visible in particular. in FIG. 9. Advantageously, the peripheral edge 13 comprises at least one ramp 15, adapted to cooperate, by a cam effect, with the maneuvering pin 51 of the locking element 5. The control plate 12 is made of material plastic. However, alternatively, the control plate 12 may be metallic.
    [0016] The control cam 11, which may be a thick metal disk, extends perpendicularly to the hinge axis Y. The control cam 11 comprises a central recess 93 defining an inner edge with at least one notch 17 , specifically three notches 17 according to the embodiment shown, intended for the rotational drive of the cam 11 and thus also of the control member 1.
    [0017] In addition, the cam 11 may comprise at least one inclined face 67, specifically six inclined faces 67 according to the embodiment shown, forming a drive member on a peripheral zone of the control cam 11.
    [0018] Furthermore, the cam 11 is capable of integrating at least one recess 26, specifically three recesses 26, advantageously blind, according to the embodiment shown, intended to receive the connecting pin 27 of the control mask 12. Finally, the cam 11 may also comprise the pin 25 formed by a stamped shape corresponding to the recess 26, and on which the second end 24 of the first spring 2 is located. More particularly, each inclined face 67 is adapted to repel the element 5, the cam 11 and the control plate 12 are held together to form the control member 1.
    [0019] Furthermore, the first hinge 10 further comprises a control shaft 3, adapted to rotate the control member 1, in particular when the user requests the control handle 95. The control shaft 3 is decoupled of the control member 30 1. Figure 7 is a partial perspective view of the control shaft 3 according to the invention. More particularly, the control shaft 3 comprises: - a control hub 6, in particular obtained by molding 3024080 14 of plastic material, - an optional connecting bar 9, preferably metal and advantageously able to connect the first joint 10 and a second articulation 20, as will be described later, and - an outer axis 7, in particular obtained by plastic molding, on which the control handle 95 is mounted.
    [0020] The control hub 6, the connecting rod 9 and the external axis 7 form an integral whole once assembled, defining the control shaft 3. However, preferentially, there remains a degree of angular freedom around Y relative to to the controller 1.
    [0021] The control hub 6 comprises at least one lobe 36, specifically three lobes 36 according to the embodiment shown, projecting radially outwards. The lobe 36 serves to support a booster function described hereinafter. In addition, the control hub 6 comprises at least one projection 37, or wall 37, specifically three projections 37 according to the embodiment shown, protruding radially outwards. The projection 37 comprises a first border 37b, called 'front', and a second border 37a opposite, called 'rear'. The projection 37 serves to drive the control member 1 by the control shaft 3, as will be described later, in particular by cooperation of the first edge 37b of the wall 37 with the edge 17b opposite the notch 17 of the cam 11. The control hub 6 also comprises an axial recess 63. According to a particular embodiment, the axial recess 63 comprises concave recesses 68 and rectangular recesses 62, of which utility will be described later.
    [0022] The control shaft 3 is returned to a rest position α1, as shown in particular in FIGS. 5 and 8, by at least one second spring 4. In the embodiment shown, there are three second springs. 4. However, there could be two or only one, depending on the restoring torque that one wishes to obtain on the control shaft 3, in other words the 'hardness' of the rotation control.
    [0023] Preferably, the second spring 4 is a spiral spring and comprises, on the one hand, a first end 43, anchoring on a pin 22, in particular semi-circular, of the first flange 81, and, on the other hand, a second end 44 slidingly bears on the lobe 36 of the control hub 6. In addition, the second spring 4 is housed in the housing 94 94, as defined above, in particular the individual bowl 94. Advantageously, the first spring 2 and the second spring 4 are identical and are mounted identically in the respective housing 94. The connecting bar 9 is preferably made of metal and optionally connects the first hinge 10 to the second hinge 20 located on the opposite side of the seat 100 relative to the first hinge 10. It is important to note that Although this case is not shown in the figures, only one hinge 10 can be used for the implementation of the present invention and in this case the connecting bar 9 is reduced to a simple mounted sleeve. on the control hub 6, in particular by crimping, in particular on a grooved portion of the control hub 6.
    [0024] Advantageously, as shown, the connecting bar 9 connects the first hinge 10 to the second hinge 20 and comprises a cylindrical tube centered on the pivot axis Y having ends comprising at least one lobe 38 being provided for housing in the concave housing 68 of the inner hub 6. In the illustrated example, three lobes 38 are each received in one of the three concave housings 68.
    [0025] The outer axis 7 of the control shaft 3 has an annular portion 73, advantageously cylindrical, from which at least one stop lobe 74 extends, specifically three stop lobes 74 according to the example of FIG. presented embodiment, provided to cooperate with at least one abutment lug 87 disposed on the seat frame 8, preferably radially. The outer axis 7 also comprises at least one fastening tab 72, advantageously flexible, specifically three fastening tabs 72 according to the embodiment shown, which extends in the axial direction. Preferably, the fixing lug 72 is designed to snap into the right-angled housings 62 of the control hub 6 as illustrated in FIG. 7.
    [0026] In addition, the angular adjustment device according to the invention may comprise, as already mentioned, a second articulation 20, advantageously a symmetrical image of the first articulation 10 with respect to the pivot axis Y, situated on the opposite side of the seat by The second hinge 3024080 17 is similar or identical to the first hinge 10, except for certain aspects which are detailed below. The second articulation 20 comprises: - a third flange 83 and a fourth flange 84 similar to the first and second flanges 81, 82 and fixed respectively to the frame of the seat and the backrest frame, the latter being secured respectively of the seat and backrest frame 10 already mentioned, with moreover a crimped peripheral ring 86, - a second control member, comprising a control plate similar to the control plate 12 of the first hinge 10 and a cam similar to the control cam 11 of the first articulation 10, second locking elements similar to the locking elements 5 of the first articulation 10, at least one third return spring similar to the first spring 2 of the first articulation 10, adapted to return the second control member to the locking position, and - an internal hub identical or similar to that previously described it.
    [0027] The internal operation of the second hinge 20 is similar to that of the first hinge 10 and will not be described again in detail.
    [0028] With reference to the figures, particularly Figure 8, the operation of the angular adjustment device is now described. For this purpose: the angular positions al, a2, a3 denote positions of the control shaft 3, the angular positions 132, 133 denote positions of the control member 1 of the first articulation 10, and the angular position 132 'denotes a locked position of the control member of the second articulation 20. At rest, the control shaft 3 is in the angular position α1, also called the rest position α1, resulting from In addition, the id rest position can also be ensured by virtue of the presence of an angular clearance e, or "dead" stroke e. By way of example, the rest position α1 has been conventionally chosen as a direction of the median of the projection 37, as shown in FIG.
    [0029] The circumferential length of the notches 17 can be dimensioned so that the rear edge 37a of the wall 37 comes into substantially contact with or near the circumferential edge of the notch 17.
    [0030] When the user actuates the control handle 95, particularly in the clockwise direction in the illustrated example, the control shaft 3 turns ("dead" travel 0) to a driving position a2 in which the projection 37 comes into contact on the opposite edge of the notch 17 of the control cam 11. In the course of the angular stroke, ie the second part of travel marked 'y', the control shaft 3 drives the body command 1 in rotation. More precisely, the control shaft 3 moves from the angular position a2, also called the driving position a2, to the angular position angular position a3 at the same time as the control member 1 moves from the position 35 angular 132, also called locking position 3024080 19 132, to the angular position 133, also called unlocking position 133, ensuring complete unlocking of the locking elements 5.
    [0031] In the second stroke portion, the control shaft 3 also drives the second control member of the second hinge 20 from the angular position 132 'which does not necessarily coincide with the angular position a2, 132.
    [0032] It should be noted that the angular position α1 of the control shaft as well as the angular position 132 of the control member are shown in solid line in FIG. 8, whereas the angular position 133 of the control member 15 is represented in dashed line. On a first part of angular stroke, during the 'dead' race, only the second spring (s) 4 oppose the rotation and the force exerted by 20 the user. On a second part of the angular stroke, along the angle y, the first spring (s) 2 and the second spring (s) 4 oppose the rotation and at the effort exerted by the user. Advantageously, the "dead" race e is typically chosen between 3 ° and 10 °. Furthermore, advantageously, the angle y is typically selected between 10 ° and 30 °, depending on the possible embodiments of the inclined surfaces 67 of the control cam 11. If the second hinge 20 (optional) is present, for the second part of the angular stroke, the first spring (s) 2, the second (s) spring (s) 4 and 3024080 20 third springs oppose the rotation and the exerted force by the user. For the second hinge 20, a 'dead' stroke e ', 5 between the angular position α1 and the angular position 132' may be slightly different from the 'dead' stroke of the first hinge 10. The 'dead' stroke e ' the second articulation 20 ensures that, the control shaft 3 being returned to the rest position a1, the first hinge 10 and the second hinge 20 are perfectly locked. To assemble the control shaft 3 in the hinge 10, the connecting rod 9 is threaded into: - the axial recess 63 of the control hub 6, - the central recess 89 of the first flange 81, - the central axial opening 92 of the control plate 12, and the central recess 93 of the control cam 11.
    [0033] Advantageously, the inner hub 6 is integrated prior to the assembly of the first flange 81 and the second flange 82 of the hinge 10.
    [0034] As a result, the outer axis 7 is clipped. The fixing lug 72, advantageously provided with a hook shape, is engaged on the control hub 6, so that the external axis 7 is immobilized axially with respect to the hinge 10.
    [0035] On the other hand, resilient tabs 75 snap into holes 39 in the connecting bar 9 provided near the end of the bar 9. An inner shoulder 79 immobilizes the bar 9 in the opposite axial direction. Thus the assembly by clipping of the outer axis 7 3024080 21 is sufficient to immobilize all the parts axially. As a result, the mechanism can be assembled manually without tools. In this way, there is no need to provide axial immobilization at the second hinge 20 when this is present. To be able to be synchronously controlled by the handle 95, the control members of the first hinge 10 and the second hinge 20 are interconnected by the control shaft 3. For this purpose, reference will be made to the description which FIG. 8. It should be noted that in the illustrated example, the operating direction of the handle 95 corresponds to the clockwise direction, but the opposite direction (trigonometric) for the operation of the handle 95 is just as possible. It should also be noted that there may be fourth springs in the second hinge 20, similar to the second springs 4, which act on the inner hub of the second hinge 20. In this case, it should be noted that the first hinge 10 and the second hinge 20 may be similar in all respects except for mirror symmetry. And so, from the logistic and industrial point of view, one can manage only two references, respectively a right and a left. Of course, the invention is not limited to the embodiments described above and provided solely by way of example. It encompasses various modifications, alternative forms and other variants that may be considered by those skilled in the art within the scope of the present invention and in particular any combination of the various operating modes described above, which may be
