Fixation de tapis d'habitacle pour véhicule automobile et procédé de montage d'un tapis d'habitacle La présente invention concerne la fixation du tapis d'habitacle sur le plancher et les parties montantes voisines du plancher d'un véhicule automobile. BACKGROUND OF THE INVENTION The present invention relates to the fixing of the cabin carpet on the floor and the rising parts adjacent to the floor of a motor vehicle.
Le tapis d'habitacle est généralement fixé au plancher par un ou plusieurs dispositifs de fixation en deux parties, par exemple du type à tenon et à douille comme connu par FR 1 364 408, ou à bouton-pression comme connu par FR 1 405 310. L'une des parties vient se placer derrière une ouverture prévue dans la tôlerie et sert d'ancrage à la queue ou analogue de l'autre partie, qui ne reste visible sur le tapis que par sa tête, généralement sous forme d'une calotte sphérique très aplatie. The cabin carpet is generally fixed to the floor by one or more two-part fastening devices, for example of the type with tenon and socket as known from FR 1 364 408, or press-button as known from FR 1 405 310 One of the parties is placed behind an opening in the sheet metal and serves as anchor to the tail or the like of the other party, which remains visible on the carpet only by its head, usually in the form of a spherical cap very flattened.
Sur les parties montantes, le tapis subit des sollicitations mécaniques liées au frottement des pieds du conducteur ou du passager qui peuvent, à la longue, entraîner une dégradation de la tenue du tapis, par bâillement ou par affaissement. La multiplication des fixations du type précédent n'est pas toujours possible, et même quand elle l'est, elle est généralement mal commode, car la formation des ouvertures dans la tôlerie et la fixation des parties d'ancrages prévus dans la tôlerie, du côté extérieur à l'habitacle, peut être rendue difficile par l'encombrement du moteur. Par ailleurs, ces solutions ne sont pas satisfaisantes quand des complexes d'insonorisation épais, du type mousse alvéolée et masse lourde, maintenant usuels, sont interposés entre la tôlerie et le tapis, car les fixations standard ne s'accommodent pas de cette épaisseur accrue; le palliatif consistant à diminuer localement l'épaisseur du complexe en faisant un embouti est inesthétique et provoque une discontinuité dans la mise en place du complexe épais. On the rising parts, the carpet undergoes mechanical stress related to the friction of the feet of the driver or the passenger who can, in the long run, cause a degradation of the resistance of the carpet, by yawning or by sagging. The multiplication of the fixings of the preceding type is not always possible, and even when it is, it is generally inconvenient, because the formation of the openings in the sheet metal and the fixing of the parts of anchorages envisaged in sheet metal, from outside the cockpit, can be made difficult by the size of the engine. Moreover, these solutions are unsatisfactory when heavy-duty foam insulation complexes, of the usual foam type and heavy mass, are interposed between the sheet metal and the carpet, because the standard fasteners do not accommodate this increased thickness. ; the palliative of locally reducing the thickness of the complex by making a stamping is unsightly and causes a discontinuity in the establishment of the thick complex.
Le but de l'invention est donc de proposer une nouvelle fixation pour tapis d'habitacle qui ne présente pas ces inconvénients. The object of the invention is therefore to propose a new attachment for cabin carpet that does not have these disadvantages.
L'invention atteint son but grâce à une fixation pour tapis d'habitacle présentant une tête et un corps monobloc, le corps comportant crans d'accrochage formant des reliefs d'accrochage unidirectionnel. Ces crans sont avantageusement incurvés en direction de la tête. Le corps est 2 2869372 avantageusement parallélépipédique et les crans sont prévus sur deux de ses faces. Selon l'invention, cette fixation est destinée à être utilisée seule et directement dans une partie semi-rigide liée au plancher, dans laquelle les crans d'accrochage pourront s'enfoncer et rester accrocher, en assurant une fixation suffisante pour les faibles sollicitations en jeu pour le maintien correct du tapis. The invention achieves its goal thanks to a fixing for cabin carpet having a head and a one-piece body, the body having hooking notches forming unidirectional hooking reliefs. These notches are advantageously curved in the direction of the head. The body is advantageously parallelepipedal and the notches are provided on two of its faces. According to the invention, this attachment is intended to be used alone and directly in a semi-rigid part linked to the floor, in which the hooking notches can sink and remain hooked, ensuring a sufficient fixation for the weak stresses in play for the proper maintenance of the carpet.
L'invention concerne aussi un procédé de montage d'un tapis d'habitacle dans un véhicule automobile, le procédé utilisant une fixation telle que définie ci-dessus. Comme indiqué plus haut, la fixation se fait dans io une partie semi-rigide liée au plancher de l'habitacle. Par semi-rigide, on entend ici un matériau qui permet l'enfoncement manuel ou à force des reliefs d'accrochage de la fixation et leur maintien en place. Cette partie semi-rigide liée au plancher de l'habitacle se trouve par exemple dans la mousse semi-rigide constituant le repose-pied à côté des pédales du poste de conducteur, ou la mousse d'un complexe d'insonorisation de type mousse alvéolée et masse lourde. The invention also relates to a method of mounting a cabin carpet in a motor vehicle, the method using a fastener as defined above. As indicated above, the attachment is made in a semi-rigid part connected to the floor of the passenger compartment. By semi-rigid means here a material that allows the manual depression or force hooking reliefs of the binding and their retention in place. This semi-rigid part connected to the floor of the passenger compartment is for example in the semi-rigid foam constituting the footrest next to the pedals of the driver's station, or the foam of a soundproofing complex type foam alveolate and heavy mass.
D'autres caractéristiques et avantages de l'invention ressortiront de la description suivante d'un exemple de réalisation. Il sera fait référence aux dessins annexés sur lesquels: La figure 1 est une vue en perspective partielle d'un habitacle de véhicule automobile, montrant les régions où s'applique notamment l'invention. Other features and advantages of the invention will emerge from the following description of an exemplary embodiment. Reference is made to the accompanying drawings, in which: FIG. 1 is a partial perspective view of a passenger compartment of a motor vehicle, showing the regions in which the invention applies in particular.
La figure 2 est vue en coupe partielle selon la ligne A-A de la figure 1, montrant la fixation de tapis selon l'invention, prise directement dans le 25 repose-pied. Figure 2 is a partial sectional view along the line A-A of Figure 1, showing the carpet attachment according to the invention, taken directly into the footrest.
La figure 3 est vue en coupe partielle selon la ligne B-B de la figure 1, montrant la fixation de tapis selon l'invention, prise directement dans le la mousse du complexe d'insonorisation. Figure 3 is a partial sectional view along line B-B of Figure 1, showing the carpet attachment according to the invention, taken directly into the foam of the soundproofing complex.
La figure 4 est une vue en perspective de détail de la fixation. Figure 4 is a perspective view of detail of the fastener.
La figure 5 est une vue de bout de la fixation de la figure 4. Figure 5 is an end view of the attachment of Figure 4.
L'habitacle représenté sur la figure 1 montre le tableau de bord 1 et le volant 2, le levier de changement de vitesse 3. Sur la partie gauche, au niveau du poste du conducteur, on trouve les pédales d'accélérateur 4, de freinage 5 et d'embrayage 6, et le repose-pied 7, sous forme de coin plus ou moins triangulaire disposé à gauche de la pédale de gauche 6. Le tapis 3 2869372 d'habitacle qui recouvre le plancher du véhicule recouvre aussi notamment la partie verticale triangulaire 8 du repose-pied 7. La proximité du repose-pied 7 et de la pédale d'embrayage 6 peut, pour les grandes pointures de pied 9, provoquer un frottement du bord de la semelle contre le côté 8 du repose-pied 7. Ce frottement à l'embrayage (flèche 10) tend à décoller le tapis (flèche 11) de son support, ce qui serait non seulement inesthétique mais de plus gênant pour le conducteur. C'est pourquoi selon l'invention on prévoit une fixation 20 disposée sur le côté 8 du repose-pied, sensiblement au niveau de la pédale d'embrayage 6. The passenger compartment shown in Figure 1 shows the dashboard 1 and the steering wheel 2, the shift lever 3. On the left side, at the driver's station, there are the accelerator pedal 4, braking 5 and clutch 6, and the footrest 7 in the form of more or less triangular wedge disposed to the left of the left pedal 6. The carpet 3 2869372 cockpit covering the floor of the vehicle also covers including the part triangular vertical 8 of the footrest 7. The proximity of the footrest 7 and the clutch pedal 6 can, for large foot sizes 9, cause friction of the edge of the sole against the side 8 of the footrest 7. This friction clutch (arrow 10) tends to take off the carpet (arrow 11) of its support, which would be not only unsightly but more annoying for the driver. This is why according to the invention there is provided an attachment 20 disposed on the side 8 of the footrest, substantially at the level of the clutch pedal 6.
io Cette fixation 20 est mieux visible en coupe sur la figure 2, et en détail sur les figures 4 et 5. This attachment 20 is better visible in section in FIG. 2, and in detail in FIGS. 4 and 5.
Comme on le voit, au niveau du repose-pied 7, on a affaire à un pavé de mousse semi-rigide 21, éventuellement associée à un complexe d'insonorisation constitué d'une mousse légère (mousse de polyuréthanne is alvéolé) 22 et d'une masse lourde (PVC chargé) 23 définissant directement la surface sur laquelle repose le tapis d'habitacle 24. L'ensemble est disposé sur la tôlerie 25, et est bordé par l'ébénisterie 29. As can be seen, at the level of the footrest 7, there is a semi-rigid foam pad 21, possibly associated with a soundproofing complex consisting of a light foam (polyurethane foam is honeycomb) 22 and a heavy mass (loaded PVC) 23 defining directly the surface on which the cockpit mat 24 rests. The assembly is disposed on the sheet metal 25, and is bordered by cabinetry 29.
La fixation 20 comporte un corps 27 allongé, de section rectangulaire. Le corps 27 comporte à une première extrémité une large tête 26 sensiblement plate, formant un plan sensiblement perpendiculaire à la direction du corps 27, et à une seconde extrémité, une pointe 31, sensiblement plate, formée de 4 faces en pointe de diamant. Sur deux faces latérales du corps 27 sont disposés des crans 35 espacés et sensiblement incurvés vers l'arrière en direction de la tête 26. Le corps 27, les crans 32 et la pointe 31 forme un ensemble rigide. La tête 26 étant d'une faible épaisseur par rapport à son diamètre, peut permettre une certaine élasticité. La largeur et la longueur du losange formant la pointe vue de bout sont inscrites sensiblement dans la surface frontale des crans, comme on le voit sur la figure 5. La forme de la fixation 20 lui permet de s'enfoncer facilement et s'ancrer dans la mousse semi- rigide 21, généralement du polystyrène expansible ou du polyuréthanne semi-rigide. La fixation est avantageusement moulée en matière plastique, par exemple en polyamide. The fastener 20 comprises an elongated body 27 of rectangular section. The body 27 has at a first end a broad, substantially flat head 26 forming a plane substantially perpendicular to the direction of the body 27, and at a second end, a substantially flat tip 31 formed of 4 diamond-tipped faces. On two lateral faces of the body 27 are arranged notches 35 spaced and substantially curved rearward towards the head 26. The body 27, the notches 32 and the tip 31 form a rigid assembly. The head 26 is of a small thickness relative to its diameter, may allow some elasticity. The width and the length of the rhombus forming the tip seen from the end are substantially inscribed in the frontal surface of the notches, as can be seen in FIG. 5. The shape of the fastener 20 allows it to be easily seated and anchored in semi-rigid foam 21, generally expandable polystyrene or semi-rigid polyurethane. The fastener is advantageously molded from a plastic material, for example polyamide.
La partie droite de la figure 1, au niveau du passager, montre le tapis 24 sous la planche de bord 1, qui comprend une partie inclinée se poursuivant par une bande verticale 28. Cette bande, si elle n'est pas tenue, 4 2869372 risque dans le temps de se lâcher et de finir par pendre (flèche 30) dans l'habitacle. C'est pourquoi selon l'invention, on prévoit aussi à cet endroit une fixation 20 analogue à celle qui a déjà été vue, et qui est aussi illustrée sur la figure 3, avant mise en place. Cette fixation 20 vient se prendre dans la mousse 22 du complexe d'insonorisation prévu dans l'habitacle. The right part of Figure 1, at the passenger level, shows the carpet 24 under the dashboard 1, which comprises an inclined portion continuing with a vertical band 28. This band, if not held, 4 2869372 risk in time to let go and eventually hang (arrow 30) in the cockpit. Therefore according to the invention, there is also provided at this location a fastener 20 similar to that which has already been seen, and which is also illustrated in Figure 3, before implementation. This attachment 20 is caught in the foam 22 of the soundproofing complex provided in the cabin.
