Description

<Desc/Clms Page number 1> <Desc / Clms Page number 1>

L'invention concerne les ensembles pour véhicule comportant un pare-chocs et une pièce de carrosserie et, plus précisément la fixation du pare-chocs à cette pièce.  The invention relates to vehicle assemblies comprising a bumper and a bodywork part, and more precisely the fixing of the bumper to this part.

Sur les véhicules, il est connu de fixer le parechocs aux ailes de carrosserie par le moyen de vis assurant une fixation rigide. Toutefois, un tel agencement présente certains inconvénients. En particulier, cet agencement ne permet pas un prémaintient du pare-chocs en position par rapport à l'aile avant leur fixation rigide l'un à l'autre. S'agissant de pièces très encombrantes, cela nécessite donc de supporter les deux pièces de façon adaptée jusqu'à ce qu'elles soient rigidement fixées l'une à l'autre. En outre, les vis peuvent s'avérer difficile à monter ou à démonter lorsqu'une réparation est nécessaire.  On vehicles, it is known to fix the bumper to the body fenders by means of screws ensuring rigid fixing. However, such an arrangement has certain drawbacks. In particular, this arrangement does not allow a pre-maintenance of the bumper in position relative to the wing before their rigid attachment to one another. As these are very bulky parts, this therefore requires supporting the two parts in an appropriate manner until they are rigidly fixed to one another. In addition, screws can be difficult to assemble or disassemble when repair is required.

Un but de l'invention est de fournir un dispositif de fixation d'un type différent, plus facilement démontable et éventuellement assurant un prémaintient relatif des deux pièces avant leur fixation rigide mutuelle.  An object of the invention is to provide a fixing device of a different type, more easily removable and possibly ensuring a relative pre-maintenance of the two parts before their mutual rigid fixing.

En vue de la réalisation de ce but, on prévoit selon l'invention un ensemble pour véhicule comportant un pare-chocs, une pièce de carrosserie, au moins un plot sur l'un parmi le pare-chocs et la pièce de carrosserie, et un organe de fixation présentant un évidement et monté mobile sur l'autre parmi le pare-chocs et la pièce de carrosserie entre une position de réception dans laquelle le plot est libre de pénétrer dans l'évidement et une position de verrouillage dans laquelle l'organe est apte de retenir le plot dans l'évidement.  With a view to achieving this aim, a vehicle assembly is provided according to the invention comprising a bumper, a bodywork part, at least one stud on one of the bumper and the bodywork part, and a fixing member having a recess and movably mounted on the other among the bumper and the bodywork between a receiving position in which the stud is free to enter the recess and a locking position in which the organ is able to retain the stud in the recess.

Un tel ensemble s'avère en général facile à monter et à démonter. De plus, il permet dans la plupart des cas d'assurer un pré-maintient relatif des deux pièces afin de faciliter leur manutention avant leur fixation rigide mutuelle.,
L'ensemble selon l'invention pourra en outre présenter au moins l'une des caractéristiques suivantes : - l'organe de fixation est monté coulissant sur ledit autre parmi le pare-chocs et la pièce de carrosserie ; - l'organe de fixation est monté mobile sur le parechocs ; - l'organe de fixation présente une rampe apte à déplacer le plot lorsque l'organe de fixation passe de la position de réception à la position de verrouillage ; - le plot présente un premier tronçon et un deuxième tronçon plus étroit que le premier tronçon, l'évidement présentant une première zone ayant une première largeur apte à recevoir le premier tronçon et une deuxième zone ayant une deuxième largeur apte à recevoir le deuxième tronçon mais inapte à recevoir le premier tronçon ; - ledit autre parmi le pare-chocs et la pièce de carrosserie présente un orifice, l'ensemble étant agencé pour que le plot pénètre dans l'orifice avant d'être reçu dans l'évidement ; - ledit un parmi le pare-chocs et la pièce de carrosserie porte deux plots associés à deux évidements respectifs de l'organe de fixation ; - le ou chaque plot est en matière plastique ; et - la pièce de carrosserie est une aile.
Such an assembly is generally easy to assemble and disassemble. In addition, it allows in most cases to ensure a relative pre-maintenance of the two parts in order to facilitate their handling before their mutual rigid fixing.,
The assembly according to the invention may also have at least one of the following characteristics: - the fixing member is slidably mounted on said other from among the bumper and the bodywork part; - The fixing member is mounted mobile on the bumper; - The fixing member has a ramp capable of moving the stud when the fixing member passes from the receiving position to the locking position; the stud has a first section and a second section which is narrower than the first section, the recess having a first area having a first width suitable for receiving the first section and a second area having a second width suitable for receiving the second section but unfit to receive the first section; - Said other one among the bumper and the bodywork part has an orifice, the assembly being arranged so that the stud enters the orifice before being received in the recess; - Said one among the bumper and the bodywork part carries two studs associated with two respective recesses of the fixing member; - the or each pad is made of plastic; and - the bodywork part is a wing.

On prévoit également selon l'invention un véhicule comprenant un ensemble selon l'invention. According to the invention, a vehicle is also provided comprising an assembly according to the invention.

Avantageusement, ce véhicule comprend un châssis, l'organe de fixation étant rigidement fixé au châssis.  Advantageously, this vehicle comprises a chassis, the fixing member being rigidly fixed to the chassis.

D'autres caractéristiques et avantages de l'invention apparaîtront encore dans la description suivante d'un mode préféré de réalisation donné à titre d'exemple non limitatif. Aux dessins annexés : - la figure 1 est une vue en perspective partielle d'un pare-chocs et d'une aile de carrosserie faisant partie d'un ensemble selon un mode préféré de réalisation de l'invention ; - la figure 2 est une vue en perspective de détails du pare-chocs et de l'aile de la figure 1 montrant le dispositif de fixation ; et - les figures 3 et 4 illustrent deux étapes de la fixation du pare-chocs sur le véhicule.  Other characteristics and advantages of the invention will become apparent in the following description of a preferred embodiment given by way of nonlimiting example. In the accompanying drawings: - Figure 1 is a partial perspective view of a bumper and a body wing forming part of an assembly according to a preferred embodiment of the invention; - Figure 2 is a perspective view of details of the bumper and the wing of Figure 1 showing the fixing device; and - Figures 3 and 4 illustrate two steps of fixing the bumper on the vehicle.

On a illustré à la figure 1 une aile 2 et un pare-chocs 4 d'un ensemble pour véhicule selon un mode préféré de réalisation de l'invention. Naturellement, l'ensemble comprend en fait deux ailes symétriques l'une de l'autre et fixées au pare-chocs à chacune des extrémités latérales ou crosses 6 de celui-ci. Dans toute la suite, il ne sera question que de l'une de ces deux ailes, sachant que la fixation de l'autre aile s'effectue de la même façon. En l'espèce, le pare-chocs 4 et les ailes 2 sont en matière plastique.  There is illustrated in Figure 1 a wing 2 and a bumper 4 of a vehicle assembly according to a preferred embodiment of the invention. Naturally, the assembly in fact comprises two wings symmetrical to one another and fixed to the bumper at each of the lateral ends or crosses 6 thereof. In the following, we will only talk about one of these two wings, knowing that the fixing of the other wing is done in the same way. In this case, the bumper 4 and the wings 2 are made of plastic.

La crosse 6 présente une face interne 7 visible sur la figure 2. Cette face porte un support 8 qui porte lui-même deux plots 10. Naturellement, on pourra varier le nombre de plots portés par chaque crosse du pare-  The butt 6 has an internal face 7 visible in FIG. 2. This face carries a support 8 which itself carries two studs 10. Naturally, the number of studs carried by each stick of the visor can be varied

chocs. Le support 8 ou contre-lame pourra être fixé à la pièce de carrosserie par encliquetage par exemple.
Figure img00040001

shocks. The support 8 or counter blade can be fixed to the bodywork by snap-fastening for example.

Chaque plot 10 a une forme de révolution autour de son axe central. Il présente un tronçon de base 12 contigu au support 8 et de forme cylindrique. En direction opposée au support 8, le plot se poursuit par un autre tronçon cylindrique 14 de diamètre inférieur au diamètre du tronçon 12. De même, à ce tronçon 14 fait suite un tronçon 16 de forme cylindrique et de diamètre inférieur au diamètre du tronçon 14. Le plot se poursuit par un tronçon 18 de forme cylindrique et de diamètre supérieur à celui du tronçon 16. Enfin, le plot s'achève par une extrémité libre 20 de forme conique. Les deux plots sont identiques entre eux. Le tronçon 16 forme entre le tronçon 18 et le tronçon 12 un étranglement qui constitue la partie du plot de plus petit diamètre et la plus étroite. Les deux plots 10 s'étendent l'un au-dessus de l'autre avec leurs axes parallèles l'un à l'autre. Each pad 10 has a shape of revolution around its central axis. It has a base section 12 contiguous to the support 8 and of cylindrical shape. In the direction opposite to the support 8, the stud continues with another cylindrical section 14 of diameter less than the diameter of the section 12. Similarly, to this section 14 follows a section 16 of cylindrical shape and of diameter less than the diameter of the section 14 The stud continues with a section 18 of cylindrical shape and of diameter greater than that of the section 16. Finally, the stud ends with a free end 20 of conical shape. The two studs are identical to each other. The section 16 forms between the section 18 and the section 12 a constriction which constitutes the part of the stud of smaller diameter and narrower. The two studs 10 extend one above the other with their axes parallel to each other.

En référence à la figure 2, l'ensemble comprend une pièce de fixation, ici constituée par une platine 22 montée mobile sur l'aile 2. La platine 22 a une forme générale plane et s'étend parallèlement à une face plane interne d'une extrémité de fixation de l'aile non destinée à être visible depuis l'extérieur du véhicule. Referring to Figure 2, the assembly includes a fixing piece, here constituted by a plate 22 movably mounted on the wing 2. The plate 22 has a generally planar shape and extends parallel to an internal planar face of a wing attachment end not intended to be visible from outside the vehicle.

La platine est en l'espèce montée mobile à coulissement par rapport à l'aile. Dans le présent exemple, ce coulissement s'effectue suivant une direction oblique dans un plan vertical. Cette direction 24 a été illustrée sur la figure 1. Le montage à coulissement de la platine 22 sur l'aile 2 est réalisé au moyen de cornières 26, ici au nombre de quatre, venues de matière depuis l'aile et The plate is in this case mounted movable to slide relative to the wing. In the present example, this sliding takes place in an oblique direction in a vertical plane. This direction 24 has been illustrated in FIG. 1. The sliding mounting of the plate 22 on the wing 2 is carried out by means of angles 26, here four in number, coming in material from the wing and

<Desc/Clms Page number 5><Desc / Clms Page number 5>

l'étendant en regard de la face de la platine opposée à l'aile, au niveau des bords de la platine.  extending it opposite the face of the plate opposite the wing, at the edges of the plate.

En regard de la platine 22, l'aile 2 présente deux orifices supérieur 28 et inférieur 30 traversant l'épaisseur de l'aile. La platine présente quant à elle deux évidements 32 allongés suivant la direction 24, identiques l'un à l'autre, et disposés en regard des orifices respectifs 28 et 30 de l'aile.  Opposite the plate 22, the wing 2 has two upper 28 and lower 30 orifices crossing the thickness of the wing. The plate for its part has two recesses 32 elongated in the direction 24, identical to each other, and arranged opposite the respective orifices 28 and 30 of the wing.

Chaque évidement 32 présente une extrémité inférieure 34 ayant une largeur suffisamment importante pour lui permettre de recevoir les tronçons 12 et 18 du plot 10 correspondant. Chaque évidemment 32 présente par ailleurs une extrémité supérieure 36 ayant une largeur inférieure à l'extrémité inférieure 34 et lui permettant de recevoir le tronçon étroit 16 du plot correspondant mais pas le tronçon 12 ni le tronçon 18 de ce plot. Les deux extrémités de l'évidement sont séparées par une zone dont les bords vont en se rapprochant l'un de l'autre et forment une transition entre ces deux extrémités.  Each recess 32 has a lower end 34 having a width large enough to allow it to receive the sections 12 and 18 of the corresponding stud 10. Each obviously 32 also has an upper end 36 having a width less than the lower end 34 and allowing it to receive the narrow section 16 of the corresponding stud but not the section 12 nor the section 18 of this stud. The two ends of the recess are separated by a zone, the edges of which approach each other and form a transition between these two ends.

De plus, l'épaisseur de la platine 22 est plus importante au niveau de l'extrémité supérieure 36 que de l'extrémité inférieure 34. La face de la platine située à l'opposée de l'aile s'étend à plus grande distance de l'aile au niveau de l'extrémité supérieure qu'au niveau de l'extrémité inférieure. La transition entre les deux niveaux s'effectue au moyen d'une rampe inclinée 38 en deux parties disposées de part et d'autre de l'évidement.  In addition, the thickness of the plate 22 is greater at the upper end 36 than at the lower end 34. The face of the plate located opposite the wing extends at a greater distance. of the wing at the upper end than at the lower end. The transition between the two levels is effected by means of an inclined ramp 38 in two parts arranged on either side of the recess.

Par ailleurs, l'extrémité de l'aile présente deux autres orifices 40 s'étendant l'un au-dessus de l'autre et respectivement au droit des orifices 28 et 30.  Furthermore, the end of the wing has two other orifices 40 extending one above the other and respectively in line with the orifices 28 and 30.

<Desc/Clms Page number 6> <Desc / Clms Page number 6>

La platine 22 présente un pied 42 de forme générale plane s'étendant dans un plan perpendiculaire à la platine en direction opposée à l'aile. La platine a ainsi de profil une forme générale d'équerre. Le pied 42 présente un orifice 44.,
Il est par ailleurs prévu sur le châssis 52 du véhicule une tôle 46 destinée à s'étendre parallèlement au pied 42 et pourvue d'un orifice 48.
The plate 22 has a foot 42 of generally planar shape extending in a plane perpendicular to the plate in the direction opposite to the wing. The plate thus has a general shape of a square. The foot 42 has an orifice 44.,
There is also provided on the chassis 52 of the vehicle a sheet 46 intended to extend parallel to the foot 42 and provided with an orifice 48.

La fixation du pare-chocs 4 sur les ailes 2 s'effectue comme suit.  The fixing of the bumper 4 on the wings 2 is carried out as follows.

Après avoir fixé les ailes 2 sur la partie du véhicule déjà constituée comprenant le châssis, on rapporte sur le véhicule une pièce de renfort de bouclier 50 comme illustré à la figure 3. Une telle pièce est connue en soi.  After having fixed the wings 2 on the part of the vehicle already made up comprising the chassis, a shield reinforcement piece 50 is attached to the vehicle as illustrated in FIG. 3. Such a piece is known per se.

L'étape suivante consiste à rapporter le parechocs ou bouclier 4 sur le véhicule. Au cours de ce montage, chacune des crosses 6 du pare-chocs est fixée à l'aile correspondante au moyen du dispositif de la figure 2 de la façon suivante. Chaque platine 22 est initialement en position haute. La réalisation du parechocs en matière plastique permet facilement d'écarter les deux crosses 61atéralement l'une de l'autre de façon à permettre d'introduire les plots 10 dans les orifices correspondants 28 et 30 de l'aile 2. Le tronçon 18 de chaque plot traverse l'orifice de l'aile et l'évidement 32 de la platine. Le tronçon étroit 16 s'étend en regard des chants de ces évidements. Quant au tronçon de base 12, il est trop large pour traverser l'orifice 30 de l'aile et vient en buté contre celle-ci.  The next step is to attach the bumper or shield 4 to the vehicle. During this assembly, each of the brackets 6 of the bumper is fixed to the corresponding wing by means of the device of FIG. 2 in the following manner. Each plate 22 is initially in the high position. The production of the plastic bumper makes it easy to separate the two brackets 61 laterally from one another so as to allow the studs 10 to be introduced into the corresponding orifices 28 and 30 of the wing 2. The section 18 of each stud passes through the orifice of the wing and the recess 32 of the plate. The narrow section 16 extends opposite the edges of these recesses. As for the base section 12, it is too wide to cross the orifice 30 of the wing and abuts against the latter.

<Desc/Clms Page number 7> <Desc / Clms Page number 7>

Une fois les deux plots reçus dans les orifices et les évidements, on fait coulisser la platine 22 vers le bas par rapport à l'aile 2. Au cours de ce mouvement, les tronçons 18 des plots viennent en appui contre les rampes 38 de la platine et sont ainsi tirés vers l'intérieur du véhicule jusqu'à venir en appui contre la face interne de la platine au niveau de l'extrémité supérieure de l'évidement correspondant. Chaque plot 10 est alors reçu au niveau de son étranglement 16 dans l'extrémité supérieure 36 de l'évidement correspondant 32. Dans cette position, le tronçon 18 de chaque plot interdit le retrait du plot hors de la platine et de l'orifice 28, 30. Par conséquent, chaque plot est alors verrouillé en position sur l'aile et sur la platine.  Once the two studs have been received in the orifices and the recesses, the plate 22 is made to slide downward relative to the wing 2. During this movement, the sections 18 of the studs bear against the ramps 38 of the plate and are thus pulled towards the interior of the vehicle until it comes to bear against the internal face of the plate at the upper end of the corresponding recess. Each pad 10 is then received at its throttle 16 in the upper end 36 of the corresponding recess 32. In this position, the section 18 of each pad prohibits the withdrawal of the pad from the plate and the orifice 28 , 30. Consequently, each stud is then locked in position on the wing and on the plate.

Dans une étape suivante, on immobilise la platine dans cette position en la fixant rigidement à la tôle 46 au moyen d'un boulonnage traversant les orifices 44 du pied 42 et 48 de la tôle 46. Le pare-chocs est alors rigidement relié à chacune des ailes. Bien entendu, il peut être par ailleurs fixé à d'autres parties du véhicule par exemple au moyen des pattes de fixation supérieures 54 illustrée sur la figure 4. Les orifices 40 de l'aile peuvent servir à fixer celle-ci à d'autre partie du véhicule par ailleurs. Par ailleurs, les ailes seront de préférence en outre fixées rigidement à d'autres parties du véhicule notamment au châssis.  In a following step, the plate is immobilized in this position by rigidly fixing it to the sheet 46 by means of bolting passing through the orifices 44 of the foot 42 and 48 of the sheet 46. The bumper is then rigidly connected to each wings. Of course, it can also be fixed to other parts of the vehicle for example by means of the upper fixing lugs 54 illustrated in FIG. 4. The orifices 40 of the wing can be used to fix the latter to other part of the vehicle otherwise. Furthermore, the wings will preferably also be rigidly fixed to other parts of the vehicle, in particular to the chassis.

Un tel dispositif de fixation peut être facilement monté ou démonté pour assurer la réparation ou la rechange de l'une des pièces le mettant en oeuvre, aile de carrosserie, pare-chocs, ou platine.  Such a fixing device can be easily assembled or disassembled to repair or replace one of the parts implementing it, body wing, bumper, or plate.

Les plots sont réalisés en matière plastique. Ils peuvent donc être assez facilement rompus sous l'effet d'un choc dépassant un certain seuil. Dans de nombreuses circonstances de choc, en particulier un choc à 16 km/h de face ou sur le côté du pare-chocs, le plot subira de la part de la platine et de l'aile un effort tranchant rompant le plot au niveau de l'étranglement 16. On réalise ainsi une fixation fusible qui évite d'endommager l'une des autres pièces. De plus, le véhicule offre dans ces circonstances peu de résistance lors d'un choc, en particulier lors d'un choc contre un piéton, en réalisant une absorption de l'énergie du choc. On pourra prévoir que chaque plot présente par exemple au niveau du tronçon 16 une amorce de rupture facilitant sa rupture en cas de choc.  The studs are made of plastic. They can therefore be quite easily broken under the effect of a shock exceeding a certain threshold. In many shock circumstances, in particular an impact at 16 km / h from the front or on the side of the bumper, the stud will suffer from the plate and the wing a sharp force breaking the stud at the constriction 16. A fusible attachment is thus produced which prevents damage to one of the other parts. In addition, the vehicle offers in these circumstances little resistance during an impact, in particular during an impact against a pedestrian, by achieving an absorption of the energy of the impact. Provision may be made for each stud to present, for example at the section 16, a breaking point facilitating breaking in the event of an impact.

Bien entendu, on pourra apporter à l'invention de nombreuses modifications sans sortir du cadre de celle-

Figure img00080001

ci. Of course, many modifications can be made to the invention without departing from the scope of the invention.
Figure img00080001

this.

On pourra prévoir que la platine 22 est montée mobile à rotation sur la pièce qui la porte.  Provision may be made for the plate 22 to be mounted movable in rotation on the part carrying it.

On pourra mettre en oeuvre l'invention pour fixer au pare-chocs une pièce de carrosserie autre qu'une aile.  The invention can be implemented to fix a bodywork part other than a wing to the bumper.

La platine 22 pourra être en matière plastique ou en métal par exemple.  The plate 22 may be made of plastic or metal for example.

On pourra prévoir que la platine est montée mobile sur le pare-chocs et non pas sur l'aile. Le montage de la pièce de fixation mobile sur le pare-chocs pourra être avantageux dans le cas où les moyens de guidage de la pièce de fixation sur la pièce de carrosserie pourraient être endommagés lors du process de finition du véhicule (par exemple, passage en cataphorèse ou en peinture) si  Provision may be made for the plate to be mounted mobile on the bumper and not on the wing. The mounting of the movable fastener on the bumper may be advantageous in the case where the means of guiding the fastener on the bodywork could be damaged during the vehicle finishing process (for example, passing cataphoresis or painting) if

<Desc/Clms Page number 9><Desc / Clms Page number 9>

la pièce de fixation était montée sur la pièce de carrosserie.  the fastener was mounted on the bodywork.

On pourra se dispenser de la fixation de la platine au châssis du véhicule. Alternativement, on pourra prévoir que c'est le fait de réaliser cette fixation qui engendre le déplacement de la pièce de fixation 22 et donc le verrouillage du pare-chocs sur les ailes.  We can dispense with the fixing of the plate to the chassis of the vehicle. Alternatively, it can be provided that it is the fact of making this fixing which generates the displacement of the fixing piece 22 and therefore the locking of the bumper on the wings.

On pourra mettre en oeuvre un dispositif de fixation avec des plots 10 susceptibles de se rompre en cas de choc sans prévoir que la pièce de fixation 22 est mobile. It is possible to use a fixing device with studs 10 capable of breaking in the event of an impact without providing that the fixing part 22 is movable.
