L' invention concerne un ensembIe comprenant un element de vehicule automobile portent une vitre equipee d'un dispositif formant pare-soleil fixe sur ledit element a proximite de la vitre et comprenant un ecran. Plus precisement, ['invention vise a permettre de filtrer de 50 a 70% de la lumiere entrant par une vitre laterale, un pare-brise, une lunette arriere The invention relates to an assembly comprising a motor vehicle element carrying a window fitted with a device forming a fixed sun visor on said element near the window and comprising a screen. More precisely, the invention aims to filter from 50 to 70% of the light entering through a side window, a windshield, a rear window

ou un ton' non opaque a l'interieur d'un vehicule. or a non-opaque tone inside a vehicle.

On connat deja des ensembles, tels que celui decrit dans FR-A-2 774 947, comprenant un dispositif fixe pres d'une fenetre de vehicule 0 automobile et presentant une position active dans laqueIle l'ecran recouvre sensiblement toute la vitre, afin d'arreter, sur sensiblement ['ensemble de ladite vitre, une partie de la lumiere la traversant, et une position rangee dans laquelle l'ecran est dispose a ltecart de la vitre, enroule sur un rouleau d'entrainement. Toutefois, compte tenu de l'interet croissant pour de tels dispositifs, il convient aujourd'hui de le proposer sur des vehicules de moyenne gamme sans augmenter notoirement le prix du vehicule. L' invention vise done a proposer une solution moins onereuse que celle du type decrit dans There are already known assemblies, such as that described in FR-A-2 774 947, comprising a fixed device near a window of a motor vehicle and having an active position in which the screen covers substantially all of the glass, in order to 'stop, on substantially [' all of said window, part of the light passing through it, and a stored position in which the screen is arranged away from the window, wound on a drive roller. However, given the growing interest in such devices, it should now be offered on medium range vehicles without noticeably increasing the price of the vehicle. The invention therefore aims to propose a less expensive solution than that of the type described in

FR-A-2 774 947 sans reduire la qualite du produit. FR-A-2 774 947 without reducing the quality of the product.

Par ailleurs, EP-A-0 410 687 decrit un ensemble comprenant un dispositif formant pare-soleil fixe pres d'une fenetre de vehicule et comprenant un ecran etirable fixe d'une part a proximite de la fenetre et d'autre part a un element deplacable presentant deux positions stables Furthermore, EP-A-0 410 687 describes an assembly comprising a device forming a fixed sun visor near a vehicle window and comprising a stretch screen fixed on the one hand near the window and on the other hand at a movable element having two stable positions

correspondent aux positions active et rangee de ['ensemble. correspond to the active and stored positions of the assembly.

Un tel ensemble ne permet de couvrir qutune faible partie de la vitre, est relativement complexe, delicat a mettre au point pour que ['element deplac,able presente ['ensemble les caracteristiques recherchees (forme de ['element en position active, deplacement progressif - pas trop violent de ['element deplacable, deplacement dans le plan de la vitre) et par consequent onereux. Autrement dit, un tel ensemble est reserve a des applications Such an assembly only covers a small part of the glass, is relatively complex, difficult to develop so that the moving element, able to present all the desired characteristics (shape of the element in active position, progressive displacement - not too violent of [the displaceable element, displacement in the plane of the glass) and consequently expensive. In other words, such a set is reserved for applications

particulieres et non a des vehicules de grande diffusion comme ['invention. particular and not to mass market vehicles like the invention.

Pour resoudre les problemes precites, ['invention propose de se distinguer des ensembles du type de celui decrit dans FR-A-2 774 947 en ce que: - le rideau est fixe a une extremite sur ledit element, et - le rideau est realise dans une matiere presentant un allongement To resolve the above problems, the invention proposes to distinguish sets of the type described in FR-A-2 774 947 in that: - the curtain is fixed at one end to said element, and - the curtain is made in a material having an elongation

elastique superieur ou egal a 100%.elastic greater than or equal to 100%.

En fixant le rideau directement sur ledit element, au lieu de 0 I'enrouler sur un rouleau d'entranement, on reduit le nombre de pieces et By fixing the curtain directly on said element, instead of rolling it up on a drive roller, the number of pieces is reduced and

d'operations d'assemblage. En outre, on reduit l'encombrement du dispositif. assembly operations. In addition, the size of the device is reduced.

L'allongement elastique superieur a 100% de la matiere constituent le The elastic elongation greater than 100% of the material constitutes the

rideau facilite ['integration du dispositif pare-soleil audit element dthabillage. curtain facilitates the integration of the sun visor device into said trim element.

Afin d'ameliorer la satisfaction procuree par ['ensemble, ['invention propose quten position rangee, le rideau soit etire, sous tension. Ainsi, lorsque ['ensemble est en position rangee, l'ecran ne risque pas de flotter ou In order to improve the satisfaction provided by the assembly, the invention proposes that in the stored position, the curtain be stretched, under tension. Thus, when the assembly is in the stored position, the screen is not likely to float or

de se deplacer.to move.

En outre, ['invention propose que: - l'ensemble comprenne en outre des moyens de prehension et des moyens d' accrochage lies a l' ecran, respectivement pour permettre a l'utilisateur de manipuler l'ecran, en particulier lorsqutil est en position rangee, et pour maintenir le store en position active, et - en position rangee, le rideau soit soumis a un etirement generant une force superieure ou egale au poids des moyens de prehension et des In addition, the invention proposes that: - the assembly further comprises gripping means and hooking means linked to the screen, respectively to allow the user to manipulate the screen, in particular when it is in position stored, and to keep the blind in the active position, and - in the stored position, the curtain is subjected to a stretch generating a force greater than or equal to the weight of the gripping means and

moyens d'accrochage.attachment means.

Ainsi, la manipulation du rideau est facilitee. En particulier, il suffit de liberer le rideau lorsqu'il est en position active pour le ramener en Thus, the handling of the curtain is facilitated. In particular, it suffices to release the curtain when it is in the active position to bring it back into

position rangee.stored position.

Selon une autre caracteristique avantageuse, ['invention propose que le rideau soit constitue de fils entrelaces suivant un motif predefini propre a autoriser un deplacement relatif entre les fils et menageant des ouvertures According to another advantageous characteristic, the invention proposes that the curtain be made up of interlaced wires according to a predefined pattern suitable for allowing relative displacement between the wires and providing openings

pour laisser passer au moins 30% de la lumiere. to let at least 30% of the light through.

Le rideau pourra par exemple etre du type tricote ou tisse, de sorte qutil presente un maillage deformable qui par sa conformation particuliere induise un allongement de chacun des fils qui soit inferieur a l'allongement The curtain could for example be of the knitted or woven type, so that it presents a deformable mesh which by its particular conformation induces an elongation of each of the threads which is less than the elongation

du rideau.of the curtain.

Un maillage deformable en jersey autorise des deformations meme si o les fils qui le constituent ne vent pas etirables. Associe a des fils ayant un fort pouvoir d'allongement elastique dans le cas de ['invention, il amplifiera ces proprietes. A deformable mesh in jersey allows deformations even if the threads which constitute it are not stretchable. Associated with threads having a strong elastic elongation power in the case of the invention, it will amplify these properties.

L'invention va apparatre encore plus clairement dans la description The invention will appear even more clearly in the description.

Le dispositif pare-soleil 4 comprend un rideau formant ecran 22, une o paste de prehension 24, une barre de tirage 26 et des crochets 28 fixes sur la portiere 6 et formant support pour maintenir la barre de tirage en position etiree. Plus precisement ici, la paste de prehension 24 est fixee sur la barre de tirage, laquelle est composee de deux parties 26a, 26b entre lesquelles le bord The panel 8 comprises a place side 8a intended to come inside the passenger compartment of a vehicle and a reverse side 8b on which the sun visor device 4 is fixed, so as not to be visible from the passenger compartment of the vehicle. The sun visor device 4 comprises a curtain forming a screen 22, a gripping o 24, a pull bar 26 and hooks 28 fixed on the door 6 and forming a support for holding the pull bar in the stretched position. More precisely here, the gripping paste 24 is fixed on the draw bar, which is composed of two parts 26a, 26b between which the edge

superieur 22b de l'ecran 22 est retenu. upper 22b of screen 22 is retained.

L'ecran presente en outre un bord inferieur 22a, oppose au bord superieur 22b, serre entre le botier 16 et le couvercle 18, afin de le maintenir The screen also has a lower edge 22a, opposite the upper edge 22b, clamps between the housing 16 and the cover 18, in order to maintain it

par rapport au panneau 8.relative to panel 8.

A la figure 2, l'ecran 22 est en position rangee, quasiment entierement dissimule entre le botier 16 et le couvercle 18, a ['exception de la pacte de prehension 24. Il presente entre son bord inferieur 22a et son bord superieur 22b une longueur 1. L'ecran 22 subit une tension suffisante d'une part pour lui eviter de battre entre le botier 16 et le couvercle 18 et d'autre part revenir de lui-meme en position rangee lorsque la barre de tirage 26 n'est pas maintenue par les crochets 28, autrement dit superieure au poids de In FIG. 2, the screen 22 is in the stored position, almost entirely concealed between the housing 16 and the cover 18, with the exception of the gripping pact 24. It presents between its lower edge 22a and its upper edge 22b a length 1. The screen 22 undergoes sufficient tension on the one hand to avoid it beating between the housing 16 and the cover 18 and on the other hand to return by itself to the stored position when the pull bar 26 is not held by the hooks 28, in other words greater than the weight of

la barre de tirage 26 et de la paste de prehension 24. the draw bar 26 and the gripping paste 24.
