Description

P I EC E D E FI XATI O N PO U R VE H I C U LE .  P I EC E D E FI XATIO N PO U R VE H I C U LE.
[0001 ] La présente invention concerne de manière générale une pièce de fixation agencée pour être montée dans un véhicule. Plus particulièrement, la présente invention concerne une pièce de fixation agencée pour être montée dans une ouverture d'une paroi d'une armature de siège de véhicule et faisant partie d'un carter masquant un crochet de fixation de siège enfant. The present invention generally relates to a fastener arranged to be mounted in a vehicle. More particularly, the present invention relates to a fastener arranged to be mounted in an opening of a wall of a vehicle seat frame and forming part of a housing masking a child seat attachment hook.
[0002] Il est connu dans l'art antérieur des pièces de fixation pour assembler des éléments à des parois fines telles que des tôles de véhicule. Le document KR101616976 décrit ainsi une pièce de fixation comprenant une portion cylindrique destinée à accueillir un élément de siège et une partie clippable destinée à être accueillie dans une armature de siège. It is known in the prior art fasteners for assembling elements to thin walls such as vehicle sheets. The document KR101616976 thus describes a fastener comprising a cylindrical portion intended to accommodate a seat member and a clippable portion intended to be accommodated in a seat frame.
[0003] En contrepartie, ce dispositif présente notamment l'inconvénient d'avoir une surface de contact extrêmement réduite avec l'armature de siège, ce qui peut résulter en des efforts importants appliqués à l'armature de siège et donc en une détérioration de cette armature, constituée en général d'une tôle de faible épaisseur. En outre, ce type de dispositif présente une résistance à l'arrachement limitée et ne convient donc pas pour des éléments d'habitacle soumis à des contraintes d'utilisation tout au long de la vie du véhicule. [0004] Un but de la présente invention est de répondre aux inconvénients du document de l'art antérieur mentionnés ci-dessus et en particulier de proposer une pièce de fixation adaptée pour être montée sur une paroi fine et bénéficiant d'une résistance à l'arrachement importante. In return, this device has the particular disadvantage of having an extremely small contact area with the seat frame, which can result in significant forces applied to the seat frame and therefore a deterioration of this frame, usually consisting of a thin sheet. In addition, this type of device has a limited pull-out resistance and is therefore not suitable for passenger compartment elements subjected to constraints of use throughout the life of the vehicle. An object of the present invention is to meet the disadvantages of the document of the prior art mentioned above and in particular to provide a fastener adapted to be mounted on a thin wall and having a resistance to the significant tearing.
[0005] Pour cela, un premier aspect de l'invention concerne une pièce de fixation agencée pour être montée dans une ouverture d'une paroi d'une armature de siège de véhicule, ladite pièce de fixation comprenant : - un corps agencé pour recevoir un élément de verrouillage et - des moyens de maintien pour maintenir le corps sur la paroi, les moyens de maintien comprenant au moins une portion articulée, caractérisé en ce que ladite au moins une portion articulée est agencée de telle sorte que, lorsque pièce de fixation est montée dans l'ouverture de la paroi et l'élément de verrouillage est reçu dans ledit corps, ladite au moins une portion articulée est verrouillée par ledit élément de verrouillage dans une position en appui sur ladite paroi. For this, a first aspect of the invention relates to a fastener arranged to be mounted in an opening of a wall of a vehicle seat frame, said fastener comprising: - a body arranged to receive a locking element and - Holding means for holding the body on the wall, the holding means comprising at least one articulated portion, characterized in that said at least one articulated portion is arranged such that, when the fastener is mounted in the opening of the wall and the locking member is received in said body, said at least one hinged portion is locked by said locking member in a bearing position on said wall.
[0006] Une telle pièce de fixation ne comprend pas de moyens de clippage et peut donc être facilement montée sur une paroi fine sans risque de déformer celle-ci. En outre, la surface de contact entre la pièce de fixation et la paroi fine est élevée, ce qui permet d'obtenir une force d'arrachement importante tout en présentant de faibles pressions de contact. Toute concentration de contrainte est ainsi évitée. Such a fastener does not include clipping means and can be easily mounted on a thin wall without the risk of deforming it. In addition, the contact area between the fastener and the thin wall is high, which allows to obtain a large tearing force while having low contact pressures. Any concentration of stress is thus avoided.
[0007] Avantageusement, ladite portion articulée comprend une face de verrouillage agencée de telle sorte que, lorsque la pièce de fixation est montée dans l'ouverture de la paroi et l'élément de verrouillage est reçu dans ledit corps, l'élément de verrouillage est en appui contre la face de verrouillage. Une telle position est stable et permet un verrouillage optimal de la portion articulée sur la paroi de l'armature de siège.  Advantageously, said articulated portion comprises a locking face arranged such that, when the fastener is mounted in the opening of the wall and the locking element is received in said body, the locking element is in support against the locking face. Such a position is stable and allows optimal locking of the articulated portion on the wall of the seat frame.
[0008] Avantageusement, ladite au moins une portion articulée et ledit corps sont en matériaux polymères et ladite au moins une portion articulée est articulée par un segment de matière polymère de faible épaisseur, telle qu'un film. Ceci permet de fabriquer la pièce de fixation d'une seule pièce pour un faible coût, par exemple par moulage.  Advantageously, said at least one articulated portion and said body are of polymeric materials and said at least one articulated portion is articulated by a segment of thin polymeric material, such as a film. This makes it possible to manufacture the fastener in one piece for a low cost, for example by molding.
[0009] De manière spécialement avantageuse, ledit corps est agencé pour prendre appui sur une première face de la paroi et ladite portion articulée est agencée pour prendre appui sur une deuxième face de la paroi opposée à ladite première face. Ainsi, la paroi est prise en sandwich entre le corps et la portion articulée, ce qui garantit une fixation solide de la pièce de fixation à ladite paroi. [0010] Avantageusement, ledit corps fait partie d'un carter agencé pour encadrer une cavité dans ladite paroi. Ledit corps constitue alors un élément d'habitacle apte à procurer une sensation de confort et de sécurité aux occupants. In a particularly advantageous manner, said body is arranged to bear on a first face of the wall and said hinged portion is arranged to bear on a second face of the wall opposite to said first face. Thus, the wall is sandwiched between the body and the articulated portion, which ensures a solid attachment of the fastener to said wall. Advantageously, said body is part of a housing arranged to frame a cavity in said wall. Said body then constitutes a cabin element capable of providing a feeling of comfort and safety to the occupants.
[001 1 ] De manière avantageuse, ledit carter comprend en outre un capot articulé apte à fermer l'accès à ladite cavité. La cavité peut être un espace de rangement ou encore abriter un élément de sécurité. La pièce de fixation permet ainsi de masquer la cavité à la vue des occupants du véhicule, accentuant ainsi la sensation de confort et de sécurité.  [001 1] Advantageously, said housing further comprises an articulated hood adapted to close the access to said cavity. The cavity may be a storage space or still house a security element. The attachment piece thus makes it possible to mask the cavity in view of the occupants of the vehicle, thereby accentuating the feeling of comfort and safety.
[0012] Un second aspect de l'invention est un module de fixation comprenant une pièce de fixation selon le premier aspect de l'invention, caractérisé en ce qu'il comprend un élément de verrouillage choisi parmi un crochet, un bouton-pression ou un aimant. Ainsi, l'élément de verrouillage sert à la fois à verrouiller la portion articulée sur la paroi, mais peut aussi servir à fixer ou attacher un autre élément au corps de la pièce de fixation et donc à la paroi de l'armature de siège.  A second aspect of the invention is a fastening module comprising a fastener according to the first aspect of the invention, characterized in that it comprises a locking element selected from a hook, a snap or a magnet. Thus, the locking element serves both to lock the articulated portion on the wall, but can also be used to attach or attach another element to the body of the fastener and thus to the wall of the seat frame.
[0013] Avantageusement, l'élément de verrouillage est un aimant et ledit module de fixation est pourvu d'un capot articulé comprenant une surface métallique agencée de telle sorte à être placée en regard dudit élément de verrouillage quand ledit capot est dans une position de fermeture. L'élément de verrouillage sert alors également à verrouiller temporairement le capot au corps de façon à éviter toute vibration ou ouverture intempestive.  Advantageously, the locking element is a magnet and said fixing module is provided with an articulated cover comprising a metal surface arranged so as to be placed opposite said locking element when said cover is in a position of closing. The locking element is then also used to temporarily lock the hood to the body so as to avoid any vibration or inadvertent opening.
[0014] Un troisième aspect de l'invention est un siège de véhicule comprenant une paroi pourvue d'une ouverture ainsi qu'un module de fixation selon le deuxième aspect de l'invention, caractérisé en ce que ladite paroi comprend une cavité pourvue d'un crochet agencé pour attacher un siège bébé.  [0014] A third aspect of the invention is a vehicle seat comprising a wall provided with an opening and a fastening module according to the second aspect of the invention, characterized in that said wall comprises a cavity provided with a hook arranged to attach a baby seat.
[0015] Un dernier aspect de l'invention est un véhicule comportant au moins une pièce de fixation, un module de fixation ou un siège selon l'un des aspects précédents de l'invention. [0016] D'autres caractéristiques et avantages de la présente invention apparaîtront plus clairement à la lecture de la description détaillée qui suit d'un mode de réalisation de l'invention donné à titre d'exemple nullement limitatif et illustré par les dessins annexés, dans lesquels : A final aspect of the invention is a vehicle comprising at least one attachment piece, a fastening module or a seat according to one of the preceding aspects of the invention. Other features and advantages of the present invention will appear more clearly on reading the following detailed description of an embodiment of the invention given by way of non-limiting example and illustrated by the accompanying drawings, wherein :
- la figure 1 représente une vue en coupe d'une pièce de fixation selon la présente invention verrouillée à une paroi d'une armature de siège de véhicule,  - Figure 1 shows a sectional view of a fastener according to the present invention locked to a wall of a vehicle seat frame,
les figures 2A à 2C représentent les différentes étapes du verrouillage d'une pièce de fixation selon la figure 1 à une paroi d'une armature de siège de véhicule.  FIGS. 2A to 2C show the different steps of locking a fastener according to FIG. 1 to a wall of a vehicle seat frame.
[0017] La présente invention concerne de façon générale une pièce de fixation adaptée pour être montée dans une ouverture d'une armature de siège. Cette pièce de fixation peut ainsi servir à fixer des éléments de siège ou tout autre élément à une telle armature. En outre, la pièce de fixation peut être intégrée à un élément d'habitacle tel qu'un carter pour crochet de sécurité, comme décrit ci-après. The present invention generally relates to a fastener adapted to be mounted in an opening of a seat frame. This fastener can be used to attach seat elements or any other element to such a frame. In addition, the fastener may be integrated with a passenger compartment element such as a safety hook housing, as described below.
[0018] Ainsi, la figure 1 représente une paroi 10 d'une armature de siège comprenant une première face 10a orientée vers l'habitacle du véhicule et une deuxième face 10b orientée vers l'intérieur du siège. La paroi 10 forme en outre une cavité 1 1 dans laquelle est pourvu un crochet 20 de sécurité. Ce crochet 20 de sécurité sert par exemple de troisième point d'ancrage pour attacher un siège bébé sur un siège de véhicule, par exemple en plus des fixations de type ISOFIX ou LATCH. Ce crochet peut en outre servir de point d'ancrage pour l'accroche de bagages ou d'une charge encombrante dans l'habitacle d'un véhicule. Thus, Figure 1 shows a wall 10 of a seat frame comprising a first face 10a facing the passenger compartment of the vehicle and a second face 10b facing towards the inside of the seat. The wall 10 further forms a cavity 1 1 in which is provided a safety hook 20. This safety hook 20 serves for example as a third anchor point for attaching a baby seat to a vehicle seat, for example in addition to fasteners of ISOFIX or LATCH type. This hook can also serve as an anchor point for the attachment of luggage or a bulky load in the passenger compartment of a vehicle.
[0019] Pour des raisons esthétiques, mais aussi de sécurité, la cavité 1 1 et le crochet 20 sont masqués à la vue des occupants du véhicule par un carter 30 comprenant un corps 31 et un capot 32 articulé par une charnière 33. Une portion du corps 31 , encerclée sur la figure 1 , fait office de pièce de fixation et est accueillie dans une ouverture 12 de la paroi 10 de telle sorte à maintenir le carter 30 fixé sur la première face 10a de la paroi 10. Cette pièce de fixation comprend des moyens de maintien et accueille un élément de verrouillage 40 tel que détaillé ci-après en référence aux figures 2A à 2C. Le crochet 20 est passé au travers de la paroi de fond de cavité du corps 31 qui est ajourée dans ce but. Il est entendu que le carter 30 est également fixé par d'autres points sur la paroi 10 (non représentés sur les figures). For aesthetic reasons, but also safety, the cavity 1 1 and the hook 20 are masked in view of the occupants of the vehicle by a housing 30 comprising a body 31 and a cover 32 hinged by a hinge 33. A portion of the body 31, encircled in Figure 1, serves as a fastener and is accommodated in an opening 12 of the wall 10 of such so as to maintain the casing 30 fixed to the first face 10a of the wall 10. This fastener comprises holding means and accommodates a locking member 40 as detailed below with reference to Figures 2A to 2C. The hook 20 is passed through the cavity bottom wall of the body 31 which is perforated for this purpose. It is understood that the housing 30 is also fixed by other points on the wall 10 (not shown in the figures).
[0020] La paroi 10 est faite d'une tôle d'acier de faible épaisseur, par exemple 0,4 mm, et le crochet 20 est par exemple en fil d'acier. En revanche, le carter 30 est réalisé en polymère rigide, tel que du polypropylène, du polyéthylène, ou de l'acrylonitrile-butadiène-styrène (ABS). The wall 10 is made of a thin steel sheet, for example 0.4 mm, and the hook 20 is for example steel wire. In contrast, the housing 30 is made of rigid polymer, such as polypropylene, polyethylene, or acrylonitrile-butadiene-styrene (ABS).
[0021 ] Les figures 2A à 2C détaillent ainsi les étapes permettant aux moyens de maintien de maintenir le carter 30 sur la paroi 10. Pour des raisons de clarté, le capot 32 a été omis des figures 2A à 2C. Ainsi, dans une première étape représentée à la figure 2A, le corps 31 comprend une ouverture 37 traversante pourvue d'un épaulement 37a et d'une embase 35 pourvue d'une gorge 35a. En vis-à-vis de l'embase 35, le carter 30 est pourvu d'une portion articulée 34 qui est articulée au corps 31 par un segment 36 de matière de faible épaisseur. Sur la figure 2A, le corps 31 est disposé sur la première face 10a de la paroi 10 de telle sorte à ce qu'un bord de la paroi 10 soit accueilli dans la gorge 35a qui applique une légère force de pincement à la paroi 10. Le carter 30 est ainsi maintenu sur la paroi 10 sans y être encore verrouillé et la portion articulée 34 est alors accueillie partiellement dans l'ouverture 12 de la paroi 10. Figures 2A to 2C and detail the steps allowing the holding means to maintain the housing 30 on the wall 10. For reasons of clarity, the cover 32 has been omitted from Figures 2A to 2C. Thus, in a first step shown in Figure 2A, the body 31 comprises a through opening 37 provided with a shoulder 37a and a base 35 provided with a groove 35a. Vis-à-vis the base 35, the housing 30 is provided with an articulated portion 34 which is articulated to the body 31 by a segment 36 of thin material. In FIG. 2A, the body 31 is disposed on the first face 10a of the wall 10 so that an edge of the wall 10 is accommodated in the groove 35a which applies a slight pinching force to the wall 10. The housing 30 is thus held on the wall 10 without being locked yet and the articulated portion 34 is then partially accommodated in the opening 12 of the wall 10.
[0022] Ainsi, l'embase 35 peut facilement loger un bord de la paroi 10 sans risque de déformation de la paroi 10 de faible épaisseur, puisque la gorge 35a n'applique qu'une force de pincement limitée sans appliquer de force déformante sur le bord de la paroi. En effet, le seul élément en vis-à-vis est la portion articulée 34 qui ne contacte pas encore la face opposée de la paroi et seul un effort minime est appliqué sur la paroi 10 au moment de la mise en place du carter 30. [0023] Dans une deuxième étape, représentée sur la figure 2B, l'élément de verrouillage 40 est introduit dans l'ouverture 37 à partir de la première face 10a, comme représenté par la flèche verticale de la figure 2B. Cet élément de verrouillage 40, qui comprend une collerette 40a, vient alors en contact avec une face de verrouillage 34a de la portion articulée 34 qui est alors animée d'un mouvement de rotation autour du segment 36 qui fait office de charnière, tel que représenté par une flèche semi-circulaire sur la figure 2B. La portion articulée se rapproche donc progressivement par rotation de la deuxième face 10b de la paroi 10. [0024] À la fin de l'insertion de l'élément de verrouillage 40 dans l'ouverture 37, comme représenté sur la figure 2C, l'élément de verrouillage 40 est complètement introduit dans l'ouverture 37 et la collerette 40a vient alors en contact avec l'épaulement 37a. De plus, l'élément de verrouillage 40 est alors complètement en contact ou en appui avec la face de verrouillage 34a de la portion articulée 34 qui est ainsi verrouillée dans une position en appui contre la deuxième face 10b de la paroi 10. La paroi 10 est alors prise en sandwich entre le corps 31 sur la première face 10a et la portion articulée 34 sur la deuxième face 10b. En outre, l'élément de verrouillage 40 est également en appui contre l'embase 35 et la paroi 10 ne peut pas s'échapper de la gorge 35a. De ce fait, le carter 30 est verrouillé à la paroi 10 et la cavité 1 1 est encadrée par le corps 31 et fermée par le capot 32 (voir figure 1 ). De plus, la surface de contact entre la paroi 10 et les moyens de maintien comprenant la portion articulée 34 et la gorge 35a est élevée et la fixation du carter 30 par les moyens de maintien présente une résistance importante à l'arrachement. [0025] De plus, de nouveau en référence à la figure 1 , l'élément de verrouillage 40 est formé d'un aimant de telle sorte à pouvoir coopérer avec une portion métallique 32a du capot 32. Ainsi, l'élément de verrouillage 40 sert à la fois à verrouiller les moyens de maintien comprenant la portion articulée 34 et la gorge 35a sur la deuxième face 10b de la paroi 10, mais aussi à réaliser un verrouillage réversible du capot 32 dans une position de fermeture de la cavité 1 1 et du carter 30. De cette façon, le capot 32 n'est pas soumis à des vibrations ou des ouvertures intempestives lorsque le véhicule est en mouvement. Enfin, l'élément de verrouillage est pourvu de moyens d'emboîtement ou de clippage (non représentés) de telle sorte à rester verrouillé dans l'ouverture 37 et à ne pas être entraîné par le capot 32 lors du passage à une position d'ouverture. Thus, the base 35 can easily accommodate an edge of the wall 10 without risk of deformation of the thin wall 10, since the groove 35a applies a limited pinch force without applying deforming force on the edge of the wall. Indeed, the only element vis-à-vis is the articulated portion 34 which does not yet contact the opposite face of the wall and only a minimal force is applied to the wall 10 at the time of installation of the housing 30. In a second step, shown in Figure 2B, the locking member 40 is inserted into the opening 37 from the first face 10a, as shown by the vertical arrow of Figure 2B. This locking element 40, which comprises a flange 40a, then comes into contact with a locking face 34a of the articulated portion 34 which is then driven in a rotational movement around the segment 36 which acts as a hinge, as shown by a semi-circular arrow in Figure 2B. The articulated portion is thus progressively closer to the wall 10 by rotation of the second face 10b. At the end of the insertion of the locking element 40 into the opening 37, as represented in FIG. locking element 40 is completely inserted into the opening 37 and the flange 40a then comes into contact with the shoulder 37a. In addition, the locking element 40 is then completely in contact or in abutment with the locking face 34a of the articulated portion 34 which is thus locked in a position bearing against the second face 10b of the wall 10. The wall 10 is then sandwiched between the body 31 on the first face 10a and the articulated portion 34 on the second face 10b. In addition, the locking element 40 is also in abutment against the base 35 and the wall 10 can not escape from the groove 35a. As a result, the casing 30 is locked to the wall 10 and the cavity 11 is framed by the body 31 and closed by the cap 32 (see FIG. 1). In addition, the contact surface between the wall 10 and the holding means comprising the articulated portion 34 and the groove 35a is high and the fixing of the housing 30 by the holding means has a high resistance to tearing. In addition, again with reference to Figure 1, the locking member 40 is formed of a magnet so as to cooperate with a metal portion 32a of the cover 32. Thus, the locking member 40 serves both to lock the holding means comprising the articulated portion 34 and the groove 35a on the second face 10b of the wall 10, but also to achieve a reversible locking of the cover 32 in a closed position of the cavity 1 1 and the housing 30. In this way, the cover 32 is not subjected to vibrations or untimely openings when the vehicle is moving. Finally, the locking element is provided with interlocking or clipping means (not shown) so as to remain locked in the opening 37 and not be driven by the cover 32 when moving to a position of opening.
