Il est bien connu que le soudage par ultra-sons d'une feuille en matière .It is well known that the ultrasonic welding of a sheet of material.

5 thermôplastique souple sur un corps en matière thermopl-astique rigide est très difficile, voire impossible.· ·5 flexible thermoplastic on a rigid thermoplastic body is very difficult, if not impossible. · ·

La présente invention se propose de trouver une solution à ce problème et, pour ce faire, elle a pour objet un procédé de soudage par ultra-sons qui se caractérise en ce qu'il consiste à placer le corps rigide sur une première sono-10 trode, à positionner la feuille souple sur la partie du corps rigide à laquelle elle doit être soudée, à appliquer sur la feuille souple une seconde sonotrode, laquelle est gravée suivant une succession de pointes en relief et est parfaite-( ment'ajustée à la partie du corps revêtue de la feuille, et à émettre des vibrations 'ultrasonores entre les deux sonotrodes pendant qu'une pression appropriée est exer-15 cée sur les pièces a souder. .The present invention proposes to find a solution to this problem and, to do this, it relates to an ultrasonic welding process which is characterized in that it consists in placing the rigid body on a first sound system. trode, to position the flexible sheet on the part of the rigid body to which it must be welded, to apply to the flexible sheet a second sonotrode, which is engraved according to a succession of points in relief and is perfectly- (adjusted to the part of the body coated with the sheet, and emitting ultrasonic vibrations between the two sonotrodes while an appropriate pressure is exerted on the workpieces to be welded.

Dans ce procédé·, les vibrations ultra-sonores sont localisées au niveau de chacune des pointes de la sonotrode gravée, de sorte qu'il se produit une soudure multi-points qui se montre suffisante pour parfaitement solidariser la feuille souple sur le corps rigide.In this process ·, the ultrasonic vibrations are localized at the level of each of the tips of the etched sonotrode, so that a multi-point welding takes place which proves to be sufficient to perfectly secure the flexible sheet to the rigid body.

20 Dans le cas particulier où il s'agit de fixer, sur une barrette de clip- \ sage en matière thermoplastique rigide portée par un pare-soleil pourvu d'une coiffe thermoplastique souple en deux éléments, un revêtement constitué de deux parties complémentaires provenant chacune d'un élément de la coiffe, le procédé de soudage se caractérise en ce qu'il consiste à disposer la barrette et les deux .25 parties complémentaires de son revêtement entre deux sonotrodes conformées de fa-çon à ce qu'elles les enserrent intimement, l'une des sonotrodes étant lisse alors que l'autre porte des pointes, a émettre un premier train de vibrations ultraso-nores entre les sonotrodes, à retourner le pare-soleil sur lui-même, à redisposer la barrette et son revêtement ainsi retournés entre les sonotrodes, et à émettre 30 un second train de vibrations ultrasonores entre les sonotrodes, une pression de soudage appropriée étant exercée pendant les émissions des vibrations.20 In the particular case where it is a question of fixing, on a clip-on bar of rigid thermoplastic material carried by a sun visor provided with a flexible thermoplastic cap in two elements, a covering made up of two complementary parts coming from each of an element of the cap, the welding process is characterized in that it consists in placing the bar and the two .25 complementary parts of its coating between two sonotrodes shaped in such a way that they enclose them intimately, one of the sonotrodes being smooth while the other carries spikes, to emit a first train of ultrasonic vibrations between the sonotrodes, to turn the sun visor on itself, to rearrange the bar and its coating thus returned between the sonotrodes, and emitting a second train of ultrasonic vibrations between the sonotrodes, an appropriate welding pressure being exerted during the emission of the vibrations.

Selon une variante de mise en oeuvre de ce procédé, on utilise deux sonôtrodes portant chacune des pointes, et on émet des vibrations ultrasonores ’ entrersonotrodes tout en exerçant une pression de soudage appropriée. Il va de soi 35 que l'utilisation de deux sonotrodes gravées permet une réduction importante du nombre des manipulations et entraîne donc une diminution notable du coût des opérations de fixation.According to a variant implementation of this method, two sonoropes are used, each carrying tips, and ultrasonic ersonal vibration vibrations are emitted while exerting an appropriate welding pressure. It goes without saying that the use of two etched sonotrodes allows a significant reduction in the number of manipulations and therefore results in a significant reduction in the cost of the fixing operations.

De préférence, les sonotrodes utilisées pour solidariser le revêtement; sur la barrette de clipsage sont semi-cylindriques, les pointes de la ou des sono-HO trodes gravées étant constituées de pet.ïtes pyramides.Preferably, the sonotrodes used to secure the coating; on the clip bar are semi-cylindrical, the tips of the sono-HO or engraved trodes being made of small pyramids.

2 ï2 ï

De telles sor.otrod.es constituent un outillage sûr et simple tout en étant relativement facile à réaliser.Such sor.otrod.es constitute a safe and simple tool while being relatively easy to produce.

Il va de soi que la présente invention couvre également les sonotrodes utilisées dans le procédé de soudage précité ainsi que les pare-soleil dont la 5 barrette de clipsage est revêtue par.la mise en oeuvre de ce procédé.'It goes without saying that the present invention also covers the sonotrodes used in the abovementioned welding process as well as the sun visors with which the clip bar is coated by the implementation of this process.

Un mode d'exécution de la présente invention est.représenté à titre d'exemple sur le dessin annexé dans lequel : - la figure 1 est une vue partielle en plan d’un pare-soleil comportant une barrette de clipsage revetue conformément au procédé de l’invention ; 10 “ la figure 2 est une vue en coupe selon la ligne II-II de la figure 1 ; - la figure 3 est une vue en coupe à plus grande échelle de la barrette de clipsage disposée entre deux sonotrodes dont l’une est gravée conformément à I l’invention ; - la figure t est une vul en perspective partielle de la sonotrode gravée ; 15 et - la figure 5 est une vue analogue à celle de la figure 3» mais montrant deux sonotrodes gravées.An embodiment of the present invention is shown by way of example in the appended drawing in which: FIG. 1 is a partial plan view of a sun visor comprising a clipping bar coated in accordance with the method of the invention; “Figure 2 is a sectional view along line II-II of Figure 1; - Figure 3 is a sectional view on a larger scale of the clip bar disposed between two sonotrodes, one of which is etched in accordance with I the invention; - Figure t is a vul in partial perspective of the etched sonotrode; 15 and - Figure 5 is a view similar to that of Figure 3 but showing two engraved sonotrodes.

Le procédé conforme à l'invention permet de souder par ultra-sons une feuille quelconque en matière thermoplastique souple sur un corps quelconque en 20 matière thermoplastique rigide. Pour de simples questions de concision, il ne sera ! toutefois décrit ci-dessous que dans le cas particulier où il est utilisé pour revêtir la barrette de clipsage d’un pare-soleil.The method according to the invention allows any sheet of flexible thermoplastic material to be ultrasonically welded to any body of rigid thermoplastic material. For the sake of brevity, it won't! However, described below only in the particular case where it is used to cover the clip-on bar with a sun visor.

Le pare-soleil représenté partiellement sur les figures 1 et 2 a été réalisé de manière connue en soi par moulage d'une mousse 1 dans une coiffe cons-25 tituée de deux éléments 2, 3» en matière thermoplastique souple, par exemple en ^ PVC. De façon classique, ces éléments ont été reliés l'un à l'autre à leur périphérie grâce à un soudage haute fréquence réalisé suivant une ligne située dans le plan médian ÎJ· du pare-soleil (figure 2).The sun visor partially shown in FIGS. 1 and 2 was produced in a manner known per se by molding a foam 1 in a cap made up of two elements 2, 3 "made of flexible thermoplastic material, for example in ^ PVC. Conventionally, these elements have been connected to each other at their periphery by means of high frequency welding carried out along a line situated in the median plane ÎJ · of the sun visor (FIG. 2).

Au voisinage de l'un de ses angles, le pare-soleil comporte une barrette 30 de clipsage cylindrique 5 dont les extrémités libres sont noyées dans la mousse et dont la partie centrale traverse un renfoncement 6, lequel est prévu dans l'un des côtés longitudinaux du pare-soleil.In the vicinity of one of its angles, the sun visor comprises a bar 30 of cylindrical clipping 5 whose free ends are embedded in the foam and whose central part passes through a recess 6, which is provided in one of the sides of the sun visor.

* Les parties 7 et 8 des éléments de coiffe 2, 3, qui entourent la barrette au moment du démoulage du pare-soleil devaient jusqu’ici être sectionnées au ni-35 veau des côtés latéraux 9 du renfoncement.* The parts 7 and 8 of the cover elements 2, 3, which surround the bar at the time of the demolding of the sun visor had hitherto been sectioned at the level of the calf of the lateral sides 9 of the recess.

Grâce au procédé conforme à l'invention, les parties 7 et 8 n'ont plus à être enlevées et peuvent en outre être solidarisées de façon satisfaisante sur la barrette de clipsage.Thanks to the process according to the invention, the parts 7 and 8 no longer have to be removed and can also be secured in a satisfactory manner on the clipping bar.

Pour réaliser cette solidarisation, on peut utiliser, comme représenté Ik3 sur la figure 3, une sonotrode lisse 10 et une sonotrode gravée 11, portant de 3 petites pointes 12, par exemple pyramidales. Ces sonotrodes qui sont semi-cylindriques ont la meme longueur que le renfoncement 6 et sont parfaitement ajustées à la barrette revêtue des parties T et 8.To achieve this joining, one can use, as shown Ik3 in FIG. 3, a smooth sonotrode 10 and an etched sonotrode 11, carrying 3 small points 12, for example pyramidal. These sonotrodes which are semi-cylindrical have the same length as the recess 6 and are perfectly adjusted to the bar coated with the parts T and 8.

Lors de la mise en oeuvre du procédé, la barrette 5 revêtue des parties 5 de coiffe 7 et 8 est disposée entre les deux sonotrodes qui sont rapprochées l'une de l'autre afin qu’elles exercent une pression appropriée sur ladite barrette, après quoi un premier train de vibrations ultrasonores est émis -entre les sonotrodes. Ces vibrations se localisent alors au niveau de chacune des pointes 12 de la sonotrode 10 et permettent l’obtention d’une soudure multi-points satisfaisante 1Q de la .partie 8 sur la barrette.During the implementation of the method, the bar 5 coated with the cap parts 5 and 7 is placed between the two sonotrodes which are brought together so that they exert an appropriate pressure on said bar, after what a first train of ultrasonic vibrations is emitted - between the sonotrodes. These vibrations are then located at each of the tips 12 of the sonotrode 10 and allow a satisfactory multi-point weld 1Q of the .part 8 on the bar to be obtained.

Pour solidariser la partie 7 sur la barrette, le pare-soleil est ensuite retourné sur lui-même et une opération analogue à la précédente est exécutée, ce ( qui permet cette fois la réalisation d’une soudure multi-points de la partie 7 sur la barrette. .....To secure part 7 on the bar, the sun visor is then turned over on itself and an operation similar to the previous one is executed, which (this time allows the realization of a multi-point weld of part 7 on the bar. .....

15 Bien entendu, une opération ultérieure de sectionnement devra être effec tuée le long des lignes de jonction V3 et 1U (figure 1 et 3) des parties 7 et 8, conjointement avec l’opération de sectionnement normalement prévue pour éliminer les bords libres des éléments 2 et 3 de la coiffe.15 Of course, a subsequent cutting operation will have to be carried out along the junction lines V3 and 1U (FIGS. 1 and 3) of parts 7 and 8, in conjunction with the cutting operation normally provided for eliminating the free edges of the elements. 2 and 3 of the cap.

Comme on vient de le voir, la solidarisation s'effectue en deine étapes 20 successives séparées par une étape de retournement du pare-soleil.As we have just seen, the joining takes place in two successive steps 20 separated by a step of turning the sun visor.

1 Pour que cette solidarisation puisse être réalisée en une seule étape, il est possible d’utiliser deux sonotrodes gravées 10a5 11a, comme représenté sur la figure 5- bans ce cas, il suffit bien entendu d’émettre un seul train de vibrations ultrasonores pour souder simultanément les parties 7 et 8 sur la barrette.1 So that this connection can be carried out in a single step, it is possible to use two etched sonotrodes 10a5 11a, as shown in FIG. 5 - in this case, it is of course sufficient to emit a single train of ultrasonic vibrations to simultaneously weld parts 7 and 8 on the strip.

^.25 Pour être complet, on notera que le revêtement de la barrette fixé confor- v mément au procédé selon l’invention présente une finition nette et précise, ce qui confère une esthétique agréable au pare-soleil.^ .25 To be complete, it should be noted that the coating of the bar fixed in accordance with the method according to the invention has a clean and precise finish, which gives a pleasant aesthetic to the sun visor.
