    [0001] 1 foldable child car seat with a top tether strap. 1. Technical Field of the Invention The field of the invention is that of childcare, and more particularly of car seats, intended to be installed in a vehicle. More specifically, the invention relates to a foldable child car seat, including its installation in a vehicle. BACKGROUND In the past, several solutions have been proposed for making foldable car seats. However, none of these solutions is adapted to meet the security requirements, as defined in European standards. Child car seats are usually attached to the seat of a vehicle via ISOFIX type clips, which are secured with rings provided for this purpose in the vehicle. In addition, means for opposing rotation of the seat around the ISOFIX clamps must be provided. It can be a support leg, or a strap of "top-tether" that connects the upper part of the backrest to a third attachment point provided in the vehicle. The implementation of such a strap of "top tether" is not easy, in the case of a foldable seat. It must be light and easy to handle, which is hardly compatible with the presence of a reinforced attachment area of the strap at the upper part of the folder. Thus, a first identified risk is the non-use of the "toptether" strap during the installation of the car seat in the vehicle. The car seat is then free to rotate around the ISOFIX forceps, which represents a danger for the child in case of shock or sudden deceleration in particular. In addition, an identified risk is that the strap of "top-tether" is insufficiently stretched. The car seat is not properly attached to the vehicle, which can represent a significant risk for the child, especially in case of shock. This risk is even greater in the case of a foldable seat, because it is advisable to check 3032400 2 not only that the ISOFIX clamps and the top tether strap are correctly installed, but also that this is the case when the seat is unfolded and fit to receive the child. OBJECTS OF THE INVENTION The invention aims to overcome at least some of these disadvantages. In particular, the invention aims to provide a foldable car seat compatible with current safety requirements. The invention also aims to provide, in at least one embodiment, a car seat 10 to prevent improper installation ("misuse" in English) of the car seat in the vehicle. 4. OBJECT OF THE INVENTION These and other objects which will appear later are attained by means of a child car seat, comprising a seat and a backrest which can assume a folded position, in which said seat is brought against said backrest, to form a compact assembly, and an unfolded position, in which a child can be installed in said seat. According to the invention, such a seat comprises a fastening strap, called strap "top tether", having a fastening element intended to be secured to a fastening point provided for this purpose in a vehicle, said strap of "Top tether" being related to said seat. It has never been proposed a foldable car seat and equipped with a strap of "top tether". According to the invention, this new approach is further exploited to provide an effective solution in terms of safety and control of the installation of this strap. Indeed, the seat to the correct installation and / or control the proper installation of this strap of "top tether". According to a particular embodiment, the car seat comprises means for controlling the proper installation of said "top tether" strap, taking into account the tension of said "top tether" strap and / or of a length minimal deployment of said strap, from said upper part of the folder. Both aspects are important security requirements, sometimes complex to controlled, and users therefore sometimes tend to ignore or neglect. According to the invention, the seat itself implements a control, exploiting its folding nature. According to a first aspect, said control means allow the installation of a child in said seat only if said strap of "top tether" has a length deployed from said upper part of the backrest of at least 200 mm.
    [0002] It is indeed necessary, and provided for by the standard, that the strap must be deployed on such a minimum length. The invention therefore proposes, according to one embodiment, to link the control of this aspect to the unfolding of the seat, and / or the possibility of unfolding. According to a second aspect, said control means allow the installation of a child in said seat only if said strap of "top tether" is tensioned with a voltage level higher than a predetermined threshold. It is also important that the strap is sufficiently tight, and it is not always easy for the user to tension the strap and / or to know if it is sufficiently tight. Here, again, according to one embodiment, the control of this aspect is related to the unfolding of the seat, and / or the possibility of unfolding. Of course, the two aspects mentioned above may be combined, or implemented independently of one another, depending on the embodiments. In particular, a seat according to the invention may comprise a mechanism for tensioning said "top tether" strap linked to a mechanism for unfolding said seat. In this case, it is the unfolding itself, that is to say the displacement of the seat, which simultaneously ensures tensioning, without the user having to worry about this operation: it suffices to move the seat so that a sufficient tension is applied: the seat actually applies an overvoltage, compared to that applied by the user when he fixed the hook of the strap.
    [0003] For example, the passage from the folded position to the unfolded position actuates tensioning means of said strap of "top tether". Said tensioning means may in particular implement a ratchet system. In the latter case, said seat can provide a lever function of said ratchet system, when moving from the folded position to the unfolded position. According to another approach, the car seat comprises locking means, prohibiting the passage from the folded position to the unfolded position, if said if said strap of "top tether" is not tensioned with a level of tension greater than said predetermined threshold .
    [0004] In this case, it is necessary to tension the strap sufficiently, before the seat can be unfolded. This avoids the case of misuses ("misuses" in English), since it is not possible to unfold the seat, and therefore to install a child, if the strap is not sufficiently tight. In this case, said blocking means may for example comprise a rod movable in rotation about a pivot shaft, having a first end in and / or along which said strap of "top tether" and a second end forming and / or controlling a locking element in rotation of said seat, so as to maintain it in its folded position when said strap of "top tether" is not tensioned with a voltage level greater than said predetermined threshold.
    [0005] In particular, said second end of the connecting rod may form or carry a stop cooperating with a cam integral with said seat. According to alternative embodiments, said pivot shaft is mounted on a cross member of said backrest or on said seat. The invention also relates to a method of installing a car seat for a child, comprising a seat and a backrest that can assume a folded position, wherein said seat is brought against said backrest, to form a compact assembly, and a position unfolded, in which a child can be installed in said seat, a fastening strap, called "top tether" strap, allowing the attachment of an upper part of the back of said seat with a fastening point 30 provided for this purpose in a vehicle.
    [0006] According to the invention, such a method notably comprises the following steps: placing the back of the car seat against the back of a vehicle seat, said car seat being in said folded position; securing the free end of said top tether strap with the attachment point provided for this purpose in the vehicle; controlling the tension and / or the extended length of said top tether strap; passage in said unfolded position of the seat, if said control is positive. Thus, according to the invention, it is the seat which ensures, or at least participates in the control, the strap being, directly or indirectly, linked to the seat and its movement. According to a particular approach, the method comprises a step of joint tensioning in the step of passage from the folded position to the unfolded position are joint, the displacement of the seat relative to the backrest ensuring the tensioning. Furthermore, the method may comprise the prior steps of: deploying two securing clamps from a storage position, in housings provided for this purpose in said folder; securing said clamps to rings provided for this purpose in the vehicle, said seat being in the folded position. 5.

DETAILED DESCRIPTION OF EMBODIMENTS OF THE INVENTION 6.1 GENERAL PRINCIPLE The general principle of the invention is based on a foldable child car seat comprising a safety system controlling the proper installation of the "top tether" webbing, in order to prevent a child from being installed and transported while this strap is not or not properly installed.
    [0007] The check may in particular relate to one of two aspects: a sufficient tension of the strap, with respect to a predetermined minimum tension threshold, or a minimum strap length (for example 200 mm) deployed from the upper part of the strap; folder. It is also possible that these two safety criteria must be respected.
    [0008] According to the invention, the passage in the unfolded position, in which the child can be installed, is possible only if this control is positive. According to the embodiments, various means are provided for carrying out this check. In a variant, it is the unfolding which ensures the tensioning and / or the deployment of a sufficient length. The control is then implicit, since the unfolding itself ensures compliance with one or more safety criteria.
    [0009] 5 It is noted here that the term "unfolded position" refers to a "complete" unfolded position, in which the installation of the child is possible (the seat base resting on the seat of the vehicle and the back of the seat taking support against the back of the vehicle). "Intermediate" unfolding positions are possible while the safety criterion or criteria are not met, in particular when the displacement of the seat 10 ensures their implementation. Figure 1 shows an example of foldable child car seat 10 in the folded position, wherein the seat 11 is folded against the back 12, in particular so as to minimize the volume of the seat 10 during transport. It can also be noted that this folded position can facilitate the establishment of ISOFIX clamps, access to the rings 15 of the vehicle is not hidden by the folder. The backrest 12 has side flanks 121, 122 which define, with the rear part 123 of the backrest, a housing in which the seat 11, on the one hand, is folded in the folded position, and on the other hand a headrest 13. This headrest can be adjustable in height (see Figure 2), for example using a conventional rack mechanism. It is here dimensioned so that, at least when in its lower position, it is fully housed in the space defined by the elements of the folder. The assembly is particularly compact, in the folded position. Of course, the various parts (folder, seat and headrest in particular) are intended to be covered with a trim and / or protection.
    [0010] The seat 11 also carries a retractor, commented thereafter. Figure 2 shows the seat 10 in the unfolded position, wherein the seat is deployed by rotation about an axis of rotation 33 (Figure 3) in a position for the installation of a child. Two connection clamps 38, 39, for example of the ISOFIX type make it possible to secure the car seat to attachment points provided for this purpose in the seat of the motor vehicle. According to the invention, such a seat is therefore equipped with a "top tether" strap 34, 3032400 8 which makes it possible to oppose a rotational movement of the seat around the ISOFIX clamps, in the event of strong deceleration. The invention allows a control of the proper installation of the strap of "top tether", using the seat, and in particular its mobile character relative to the folder.
    [0011] This control comprises at least one of the following aspects: the control of a minimum deployed length of the "top tether" strap and the control of a sufficient tension thereof, with respect to a predetermined threshold. According to the embodiments, the seat provides this control, the displacement thereof from a folded position to an unfolded position being possible only if the control or controls are positive, or at least partially the required operation of deploying a strap length and / or tension thereof, when moving from the folded position to the unfolded position. Thus, in all cases, the strap of "top tether" is tied to the seat, and the invention uses the mobility thereof relative to the folder to ensure compliance with at least one safety condition ( minimum length and / or voltage). 6.2 Particular embodiment of implementation of the ISOFIX clamps According to one embodiment, these clamps 38, 39 are mounted in rotation about the axis of rotation 33, independently of one another.
    [0012] These clips may be stored, when not in use, in locations (not shown) provided for this purpose in the lower end of the posts 321, 322 of the backrest structure. In their position of use, the clamps 38, 39 are connected to the anchoring elements of the vehicle, while remaining mobile in rotation relative to the amounts of the backrest. These independent movements allow, in case of shock, a better dissipation of energy, particularly in cooperation with the shape of the structure of the backrest and the seat. More precisely, in this embodiment, the connection clamps 38, 39, for example of the ISOFIX type, make it possible to secure the car seat to anchoring points provided for this purpose in the seat of the motor vehicle. These clamps are mounted around the axis of rotation of the seat base relative to the backrest, in locations provided for this purpose in the lower end of the uprights 321, 322 of the 3032400 9 backrest structure. These locations have an inverted U profile and are pierced laterally holes adapted to receive the axis of rotation of the seat and clamps. The clamps 38, 39 have an anchor hook 311 connecting to the anchoring elements provided in the vehicle, the hook being rotatable relative to the clamp body. The upper part of the hook 311 is connected to a spring 312, itself linked to a fork 313 movable in translation. In their position of use, the clamps 38, 39 are connected to the anchoring elements of the vehicle, while remaining rotatable relative to the uprights 321, 322 of the folder. This allows the dissipation of energy. An unlocking system is provided in the lower end of each of the uprights 321, 322 of the backrest structure, as shown in FIGS. 3A-3D. This system comprises: an unlocking control comprising an arm 41 whose first end, facing upwards from the upright, is provided with a block 42, and a second end of which, directed towards the bottom of the upright, comprises a free portion 43. This arm 41 is rotatably connected to the upright 321 by a pivot connection 44; a spring 50 having two rods 51, 52, a first rod 51 being connected to the first end of the arm of the unlocking control, a second rod 52 being fixed to the amount 321 of the backrest structure; a locking indicator 60 mounted pivotally sliding on the axis of the spring at a first end, and provided with a rod 61 at a second end thereof. This rod 61 is in pivot connection with the fork 313 controlling the rotation of the anchoring hook 311 of the clamp 39, via the spring 312.
    [0013] The operation of the system is therefore as follows: in the position of use, the clamps 38, 39 are stowed at the vehicle anchoring points, the unlocking controls being aligned vertically with the uprights 321, 322, as illustrated by the figures 3B, 3C and 3D. When a user wishes to unlock the clamps 38, 39 to move the car seat for example, it acts on the block 42 and thus lowers the arm 41 30 of the unlocking control. The arm 41, in rotation relative to the upright 321, actuates the locking indicator 60 via its free portion 43. The control 60, while moving, in turn acts on the fork 313, which by translating acts on 3032400 the spring 312, which rotates the anchor hook 311 upwards. The clips can then be removed from the anchor locations of the vehicle. The arm 41 of the locking control, in lowering, exerts a force on the first rod 51 of the spring 50, the latter being held fixed relative to the upright 321 of the backrest by virtue of its second rod 52. Thus, the arm 41 naturally returns to its initial position when the user releases the pressure. These clamps can be straightened and then held in position in housings provided at the back of the seat back. This feature limits the size of the seat when not in use, and thus facilitate its transport and storage. This mode of storage clamps, and the fact that they can be deployed independently of each other, facilitates installation, particularly in the case of a foldable seat (which installation clamps is then that the seat is still folded). The axis of rotation 33 provides the connection between the seat and the seat back and the rotational mobility of one relative to the other. It makes it possible, in particular, to move the seat 11 in rotation with respect to the backrest 12. It should be noted that this particular solution of ISOFIX clamps may, in whole or in part, be implemented on other types of car seat, in particular non-foldable . 6.3 first approach According to a first approach, specific control means are provided to allow the unfolding of the seat only when the security criterion (s) are fulfilled. As long as this is not the case, the seat can not be unfolded, and therefore remains substantially parallel to the backrest (or, at the very least, can not take the unfolded position in which a child can be installed in the seat. seat). According to a particular embodiment, the top tether strap acts on a blocking element, movable between a locking position (default position, preventing the unfolding of the seat) and an unlocking position (allowing the unfolding, 30 as soon as the strap is sufficiently tight 3032400 11 6.4 first example of implementation Figure 4 shows the structure of the seat 10 in unfolded position according to a first embodiment The structure 32 of the backrest 12 is connected to the structure 31 of the seat 11 by the intermediate axis 5 flowing in the structures of the seating seat 10 to a vehicle by fixing a vehicle provided for this purpose.The other end of the rotational strap 33. The strap of "top- tether "34, and the backrest 31, 32, thus allows to secure the one of its ends to a point of attachment of the" top-tether "34 is engaged in a ratchet tensioner 55 located below the structure of the seat 31 and 10 e via a handle 56 allowing the tensioning of the "top-tether" strap 34. The loosening of the "top tether" strap is effected by an action on a release button or the pawls of the winder tensioner 55 This release button can for example be placed under the seat. The "top-tether" strap 34 also circulates in a security system 57 fixed to the structure of the backrest 32. This security system 57, as illustrated in FIG. 5, comprises a connecting rod 64 connected to the structure of the backrest 32 via a pivot 65. The strap "toptether" 34 extends along the rod 64 and comes into contact therewith at a first end 66 of the rod 64, and At the level of the pivot 65. Alternatively, the "top-tether" strap can pass through the end 66 of the connecting rod 64. As illustrated in FIGS. 6 and 7, a second end 67 of the connecting rod 64 forms a stop cooperating with a cam 71, for example of semi-cylindrical shape, which is located at the axis of rotation 33 and which is fixed either in the seat 11, or directly on the axis of rotation 33.
    [0014] Thus, the security system 57, comprising the connecting rod 64 and the cam 71, makes it possible to block the rotation of the seat 11 so as to prevent the installation of the child as long as the tension level of the strap of top-tether "34 does not exceed a predetermined threshold. At the beginning of the installation of the seat 10 in the vehicle, the seat 11 is folded 30 against the backrest 12, and the strap of "top-tether" 34 is not yet put in tension. The seat 10 is then locked in the folded position via the end 67 of the rod 64 which abuts against the cam 71, and thus prevents rotation of the seat 3032400 12 11 around the axis of rotation 33. This abutment of the end 67 against the cam 71 may for example arise from an imbalance at the pivot connection 65 which is mainly created by the difference in weight and / or shape between the first and second ends 66, 67 of the rod 64. Thus, in the absence of external constraints, the connecting rod 64 naturally tends to pivot towards its rest position in which the end 67 abuts against the cam 71. Where appropriate, a return spring at the pivot 65 may be provided to pre-constrain the rod 64 to adopt the rest position, as long as the voltage is not sufficient.
    [0015] During the installation of the seat 10 (still folded) in the vehicle, the strap of "top-tether" 34 is attached to the vehicle and then tensioned by the handle 56 connected to the ratchet tensioner 55. Beyond of a predetermined threshold (corresponding to a sufficient tension in terms of safety), the tension level of the "top-tether" strap 34 is such that it now exerts a sufficiently high force on the first end 66 so that the rod 64 can pivot in the direction corresponding to the stop output of the second end 67 relative to the cam 71. The seat 11 is then free to pivot about the axis of rotation 33 to an unfolded position since, as illustrated in FIG. 7, the cam 71 is no longer locked in rotation by the end 67.
    [0016] For the removal of the seat 10, the seat 11 must be folded against the backrest 12 in a folded position suitable for transporting the seat 10. To lock the seat 10 again in this folded position, the "top-tether" strap 34 must be loosened, via the button acting on the pawl (s) of the retractor 55. This button is placed under the seat, so that it is only accessible when this seat is folded (it is thus not particularly it is not possible to relax the strap if a child is in the seat). When the seat is folded and the tension level of the strap "toptether" 34 is below a predetermined threshold, the force exerted by the strap 34 on the first end 66 of the rod is no longer sufficient to maintain the second end 67 out of its stop position. The rod 64 then pivots around the pivot 65 30 to return to its rest position in which the second end 67 abuts against the cam 71, thereby locking the seat 10 in the folded position. Alternatively, it can be provided that the unlocking button is accessible 3032400 13 when the seat partially rectified. The user then unhook the strap "top tether" from its point of attachment to the vehicle. 6.5 Second Example of Embodiment FIGS. 8 and 9A to 9C show a second embodiment in which the security system 90 is mounted on the seat structure 31 rather than the backrest structure 32. Similar to the first embodiment described embodiment, the strap "top-tether" 34 comes along the security system 90 which comprises a connecting rod 91 mounted on the seat structure via a pivot connection 92. A first end 93 of the connecting rod 91 is in contact with the strap "top-tether" 34, while a second end 94 forms a stop cooperating with a cam 95 mounted on the axis of rotation 33 of the seat structure 31. The installation of the seat in the vehicle is done in several times. The ISOFIX forceps 38, 39 are first deployed (in the embodiments where it is provided that they can be retracted, by rotation and / or translation, into the backrest and / or the seat), for bring in a position for their attachment to the rings 381 provided for this purpose in the vehicle. These clamps 38, 39 are secured to these rings 381, the seat being in a folded position, the seat 11 being placed against the backrest 12, as illustrated in FIG. 9A (these preliminary steps being similar to those which can be put into position). other embodiments). As long as the "top-tether" strap 34 does not have a level of tension higher than a predetermined threshold, the second end 94 of the connecting rod 91 abuts against the cam 95, thus blocking the rotation of the seat structure 31 around the axis of rotation 33, as shown in Figure 9A.
    [0017] This abutting of the end 94 against the cam 95 may for example be due to an imbalance at the pivot connection 92 which is mainly created by the difference in weight and / or shape between the first and second ends 93. , 94 of the connecting rod 91. Thus, in the absence of external constraints, the connecting rod 91 naturally tends to pivot towards its rest position in which the second end 94 is in abutment against the cam 95. Alternatively, a return spring at the pivot 92 could pre-constrain the rod 91 to adopt a stop position at its second end 94.
    [0018] According to a principle similar to that of the first embodiment, the tensioning of the "top-tether" strap 34 beyond a predetermined threshold induces a sufficient force at the first end 93 to rotate the rod 91 in the stop output direction of the second end 94 relative to the cam 95, as shown in FIG. 9B. To obtain this sufficient tension, the user acts on a ratchet tensioner 55, after having of course attached to a ring provided for this purpose in the vehicle the free end of the strap of "top tether". This ratchet retractor 55 can be of any type known per se and adapted to the situation.
    [0019] The seat structure 31 can then pivot freely around the axis of rotation 33 so as to adopt an unfolded position allowing the child to be installed in the seat 10, as illustrated in FIG. 9C. Conversely, for the removal of the seat 10, the seat 11 must be folded against the backrest 12 in a folded position adapted to transport the seat 10. To lock the seat 10 again in this folded position, the strap of "top- tether "34 must be loosened by means of a button (not shown) for release of the roller tensioner 55. When the tension level of the" top-tether "strap 34 is to be lower than a predetermined threshold, the force exerted by the strap 34 on the first end 93 is no longer sufficient to hold the second end 94 out of its abutment position. The rod 91 then pivots about the pivot 92 to return to its rest position in which the second end 94 abuts against the cam 95, thus locking the seat 10 in the folded position. As indicated above, this rest position of the rod 91 can be ensured by an imbalance or by a prestressing force due for example to a return spring at the pivot 92.
    [0020] As illustrated in FIGS. 9A to 9C, the "top-tether" strap 34 thus circulates in the structure of the backrest 32 and the seat structure 31 while coming alongside the security system 90. A deflector 96 serves as support to the strap "top tether" 34 when changing direction between the backrest and the seat. One end of the "top-tether" strap 34 is engaged in a retractor 55 which can be actuated by a handle 56 enabling tensioning of the "top-tether" strap 34. 3032400 15 6.6 second approach As an alternative , the seat 11 itself can be used as a lever ratchet. In this case, it is not completely held against the backrest, as long as the voltage is insufficient: the blocker is adapted to allow a range of intermediate rotation (without being able, of course, to reach the completely unfolded position). Several back and forth of the seat in this range of rotation allow to stretch the strap, intuitively. 6.7 Third Implementation Example 10 According to a third embodiment, the tensioning of the "top-tether" strap is done in conjunction with the deployment of the seat to an unfolded position. To do this, tensioning means such as a ratchet system are actuated during the passage of the seat from the folded position to the unfolded position. The tensioning and unfolding operations are then joined. Prior checking control means that the top-tether strap has been hooked, with a minimum tension, can however be provided, for example according to one of the conventional techniques. 6.8 fourth example of implementation Motorized tensioning means may also be envisaged, to ensure sufficient tension. 6.9 extended length control A minimum deployment check of the top tether strap can also be provided. It is indeed necessary that a length of at least 200 mm 25 is available from the upper part of the file. According to one embodiment, when the top tether strap is fully wound (the hook thus being in contact with the backrest, for example in a housing provided for this purpose), the seat is held in the folded position against the folder. The user then pulls on the strap, to extract it, and thus unroll it from the reel. When a minimum length is extracted, here 200 mm, the seat is released. This detection of a sufficient length may for example be performed at the reel, controlling a corresponding number of turns.
    [0021] 3032400 16 Then, the hook is attached to the vehicle, and the strap is stretched, for example by acting on the lever of the ratchet tensioner, or by unfolding the seat.
