Description

L'invention concerne les blocs optiques de véhicule automobile.The invention relates to motor vehicle light units.

Certains blocs optiques de véhicule automobile comprennent un masque muni d'une ouverture arrière (logeant éventuellement une source de lumière) et d'une ouverture avant au niveau de laquelle est solidarisé un écran, éventuellement intermédiaire, assurant au moins une fonction optique, comme par exemple cacher le foyer et diffuser la lumière émise par la source de lumière et/ou colorer la lumière (par exemple en rouge ou en orange).Some motor vehicle optical units comprise a mask provided with a rear opening (possibly housing a light source) and a front opening at which is secured a screen, possibly intermediate, providing at least one optical function, as per example hide the focus and diffuse the light emitted by the light source and / or color the light (eg red or orange).

Dans la plupart des blocs optiques, l'écran obture totalement l'ouverture avant du masque, ce qui provoque une accumulation de chaleur à l'intérieur du masque, derrière l'écran.In most optical blocks, the screen completely closes the front opening of the mask, causing heat build-up inside the mask behind the screen.

Par ailleurs, l'écran est fixé sur la paroi du masque qui délimite l'ouverture avant au moyen de pattes périphériques clippées dans des gorges ou logées dans des gorges et soudées (par exemple par ultrasons). En raison de leur nombre, les pattes périphériques et les gorges doivent être sensiblement verticales, si bien qu'elles sont partiellement visibles de l'extérieur (formation d'une zone sombre), ce qui nuit à l'esthétique du bloc optique. En outre, le soudage des pattes périphériques dans les gorges nécessite un outil de soudage spécifique et interdit le remplacement de l'écran lorsqu'il est endommagé ou cassé ou lorsque l'on veut modifier sa couleur pour obtenir un effet de style.Furthermore, the screen is fixed on the wall of the mask which defines the front opening by means of peripheral tabs clipped into grooves or housed in grooves and welded (for example by ultrasound). Because of their number, the peripheral legs and grooves must be substantially vertical, so that they are partially visible from the outside (formation of a dark area), which affects the aesthetics of the optical block. In addition, the welding of the peripheral tabs in the grooves requires a specific welding tool and prohibits the replacement of the screen when it is damaged or broken or when one wants to change its color to obtain a style effect.

L'invention a donc pour but de proposer un bloc optique de véhicule automobile qui ne présente pas tout ou partie des inconvénients précités.The invention therefore aims to provide a motor vehicle optical unit that does not have all or part of the aforementioned drawbacks.

Elle propose plus précisément un bloc optique pour un véhicule automobile, comprenant un masque (éventuellement pour une source de lumière) et un écran destiné à être solidarisé au masque au niveau d'une ouverture avant.It more specifically proposes an optical unit for a motor vehicle, comprising a mask (possibly for a light source) and a screen intended to be secured to the mask at a front opening.

Ce bloc optique se caractérise par le fait que :

  • son écran comprend un bord périphérique muni d'une patte de fixation sur un côté supérieur, et
  • son masque comprend une paroi avant délimitant au moins une partie supérieure de l'ouverture avant et munie d'un moyen de fixation propre à coopérer avec la patte de fixation pour fixer l'écran au masque dans une position suspendue au niveau de son ouverture avant.
This optical block is characterized by the fact that:
  • its screen includes a peripheral edge provided with a bracket on an upper side, and
  • its mask comprises a front wall delimiting at least an upper portion of the front opening and provided with a own fastening means to cooperate with the fixing lug to fix the screen to the mask in a suspended position at its front opening .

Le bloc optique selon l'invention peut comporter d'autres caractéristiques qui peuvent être prises séparément ou en combinaison, et notamment :

  • le bord périphérique de l'écran peut être muni d'au moins une patte de calage sur au moins un côté latéral, et la paroi avant peut être munie d'au moins un moyen de calage, chaque moyen de calage étant alors propre à coopérer avec une patte de calage correspondante pour caler latéralement l'écran par rapport au masque. Ce calage latéral permet de limiter les contraintes subies par l'écran et donc de réduire son usure (améliorant ainsi sa longévité) ;
  • l'écran peut obturer partiellement l'ouverture avant du masque ;
  • la patte de fixation peut comprendre une partie terminale libre munie d'un ergot. Dans ce cas, le moyen de fixation comprend au moins un trou traversant défini dans la paroi avant et propre à recevoir l'ergot ;
    • ➢ le moyen de fixation peut comprendre en outre une saillie définie sur une face arrière de la paroi avant au voisinage du trou traversant et définissant une surface d'appui pour l'ergot de la patte de fixation ;
    • ➢ l'ergot de la patte de fixation peut être orienté vers la face arrière de la paroi avant du masque ;
  • la patte de fixation peut être définie sensiblement au milieu du côté supérieur du bord périphérique de l'écran ;
  • chaque moyen de calage peut comprendre au moins un trou traversant défini dans la paroi avant et propre à recevoir une partie terminale d'une patte de calage correspondante ;
    • ➢ chaque moyen de calage peut comprendre en outre deux protubérances définies sur une face arrière de la paroi avant de part et d'autre de son trou traversant et l'une en face de l'autre, et propres à caler latéralement l'écran par rapport au masque ;
  • le bord périphérique de l'écran peut être également muni d'une autre patte de fixation sur un côté inférieur. Dans ce cas, le masque comprend une paroi arrière solidarisée à sa paroi avant et munie d'un autre moyen de fixation propre à coopérer avec l'autre patte de fixation pour fixer l'écran au masque dans une région inférieure ;
    • ➢ l'autre patte de fixation peut comprendre une partie terminale libre munie d'un ergot. Dans ce cas, l'autre moyen de fixation comprend au moins un trou traversant défini dans la paroi arrière et propre à recevoir l'ergot ;
    • ➢ l'autre patte de fixation peut être positionnée de façon excentrée sur le côté inférieur du bord périphérique de l'écran.
De préférence, le moyen de fixation est propre à coopérer élastiquement avec ladite patte de fixation pour fixer ledit écran audit masque dans une position suspendue au niveau de son ouverture avant (OA). Ainsi, la coopération est réversible. L'écran peut être démonté du masque.
De préférence, l'écran est rectangulaire. Avantageusement, l'écran ne comprend qu'une seule patte de fixation sur son bord périphérique supérieur.The optical block according to the invention may comprise other characteristics that can be taken separately or in combination, and in particular:
  • the peripheral edge of the screen may be provided with at least one locking lug on at least one lateral side, and the front wall may be provided with at least one wedging means, each wedging means then being adapted to cooperate with a corresponding locking lug to wedge the screen laterally relative to the mask. This lateral stalling makes it possible to limit the stresses on the screen and thus to reduce its wear (thus improving its longevity);
  • the screen may partially close the front opening of the mask;
  • the fixing lug may comprise a free end portion provided with a lug. In this case, the fixing means comprises at least one through hole defined in the front wall and adapted to receive the lug;
    • The fixing means may further comprise a projection defined on a rear face of the front wall in the vicinity of the through hole and defining a bearing surface for the lug of the fixing lug;
    • The lug of the fixing lug can be oriented towards the rear face of the front wall of the mask;
  • the bracket may be defined substantially in the middle of the upper side of the peripheral edge of the screen;
  • each setting means may comprise at least one through hole defined in the front wall and adapted to receive an end portion of a corresponding locking tab;
    • Each locking means may further comprise two protuberances defined on a rear face of the front wall on either side of its through hole and facing each other, and capable of wedging laterally the screen relative to the mask;
  • the peripheral edge of the screen may also be provided with another bracket on a lower side. In this case, the mask comprises a rear wall secured to its front wall and provided with another own fastening means to cooperate with the other fixing lug to fix the screen to the mask in a lower region;
    • The other fixing lug may comprise a free end portion provided with a lug. In this case, the other fastening means comprises at least one through hole defined in the rear wall and adapted to receive the lug;
    • ➢ the other bracket can be positioned eccentrically on the lower side of the peripheral edge of the screen.
Preferably, the fixing means is adapted to cooperate elastically with said fixing lug to fix said screen to said mask in a suspended position at its front opening (OA). Thus, cooperation is reversible. The screen can be removed from the mask.
Preferably, the screen is rectangular. Advantageously, the screen comprises only one bracket on its upper peripheral edge.

L'invention a pour but de proposer un bloc optique (BO) destiné à être implanté dans un véhicule automobile.The object of the invention is to propose an optical block (BO) intended to be implanted in a motor vehicle.

Dans ce qui suit, on considère, à titre d'exemple non limitatif, que le bloc optique BO est un feu arrière de signalisation destiné à être installé à l'arrière d'un véhicule automobile. Mais, l'invention n'est pas limitée à ce type d'implantation. Elle concerne également certains blocs optiques, comme par exemple des phares (ou projecteurs avant), destinés à être installés à l'avant d'un véhicule automobile.In what follows, it is considered, by way of non-limiting example, that the optical block BO is a signal rear lamp to be installed in the rear of a motor vehicle. But, the invention is not limited to this type of implantation. It also relates to certain optical blocks, such as headlights (or headlights), intended to be installed in the front of a motor vehicle.

On se réfère tout d'abord aux figures 1 à 6 pour présenter un bloc optique BO selon l'invention.We first refer to Figures 1 to 6 to present an optical block BO according to the invention.

Un bloc optique BO, selon l'invention, comprend un boîtier (non représenté) dans lequel se trouve installé un masque (voir figures 1 et 4) auquel est fixé au moins un écran EC (voir figures 2 et 3). On notera que le bloc optique BO peut éventuellement comprendre en complément une glace (non représentée) placée devant son écran EC et solidarisée à son boîtier. L'écran EC est alors appelé écran intermédiaire.An optical block BO according to the invention comprises a housing (not shown) in which a mask is installed (see figures 1 and 4 ) to which at least one EC screen is attached (see figures 2 and 3 ). Note that the optical block BO may optionally further include a mirror (not shown) placed in front of its screen EC and secured to its housing. The EC screen is then called the intermediate screen.

Comme illustré sur la figure 1, le masque M comprend une paroi arrière PR, dans laquelle sont définies une éventuelle ouverture arrière OR, destinée à recevoir une partie au moins d'une éventuelle source de lumière (non représentée), et une partie inférieure d'une ouverture avant OA, destinée à recevoir l'écran EC, et une paroi avant PV, solidarisée à la paroi arrière PR et délimitant une partie supérieure de l'ouverture avant OA.As illustrated on the figure 1 , the mask M comprises a wall rear PR, in which are defined a possible rear opening OR, intended to receive at least a portion of a possible light source (not shown), and a lower portion of a front opening OA, for receiving the EC screen , and a front wall PV, secured to the rear wall PR and delimiting an upper portion of the front opening OA.

On notera que la face avant FV de la paroi avant PV est une face qui est destinée à être orientée vers l'extérieur (voir figure 1), et la face arrière FR de la paroi avant PV est la face qui est destinée à être orientée vers l'habitacle du véhicule automobile (voir figure 4).It will be noted that the front face FV of the front wall PV is a face which is intended to be oriented towards the outside (see figure 1 ), and the rear face FR of the front wall PV is the face which is intended to be oriented towards the passenger compartment of the motor vehicle (see figure 4 ).

On notera également que l'écran EC ne présente pas forcément des dimensions sensiblement identiques à celles de l'ouverture avant OA. En effet, comme illustré sur les figures 8 et 9, il est avantageux que l'écran EC n'obture que partiellement l'ouverture avant OA du masque M afin d'éviter l'accumulation de chaleur à l'intérieur du masque, derrière l'écran EC.It should also be noted that the screen EC does not necessarily have dimensions substantially identical to those of the front opening OA. Indeed, as illustrated on figures 8 and 9 it is advantageous for the screen EC to partially close the front opening OA of the mask M in order to prevent the accumulation of heat inside the mask, behind the screen EC.

Comme illustré sur les figures 2 et 3, l'écran EC comprend une paroi principale PP délimitée par un bord périphérique BP comportant un côté dit supérieur CS, un côté dit inférieur CI (opposé au côté supérieur CS), et deux côtés latéraux CLi (i = 1 ou 2) joignant les côtés supérieur CS et inférieur CI. On notera, comme illustré non limitativement, que le bord périphérique BP peut éventuellement comporter une partie repliée vers l'intérieur (par exemple à environ 90°) qui définit un rebord RB. Dans l'exemple illustré, le rebord RB comprend les côtés latéraux CL1 et CL2 et le côté inférieur CI du bord périphérique BP.As illustrated on figures 2 and 3 , the screen EC comprises a main wall PP defined by a peripheral edge BP having a so-called upper side CS, a said lower side CI (opposite the upper side CS), and two lateral sides CLi (i = 1 or 2) joining the upper sides CS and lower CI. It will be noted, as illustrated without limitation, that the peripheral edge BP may optionally comprise an inwardly folded portion (for example at about 90 °) which defines a flange RB. In the example illustrated, the flange RB comprises the lateral sides CL1 and CL2 and the lower side CI of the peripheral edge BP.

On notera, comme illustré non limitativement sur la figure 3, que la paroi principale PP peut éventuellement comporter (par exemple sur sa face arrière (ou interne)) ce que l'homme de l'art appelle un billage destiné à cacher le foyer.It will be noted, as illustrated without limitation on the figure 3 , that the main wall PP may optionally comprise (for example on its rear face (or internal)) what the skilled person calls a billage to hide the focus.

Selon l'invention, le bord périphérique BP est muni sur son côté supérieur CS d'une patte de fixation PF1 dite supérieure. De préférence, le bord périphérique BP est également muni sur au moins l'un de ses deux côtés latéraux CLi d'au moins une patte de calage PCi. Dans l'exemple non limitatif illustré sur les figures 2 et 3, le bord périphérique BP est muni d'une patte de calage PCi sur chacun de ses deux côtés latéraux CLi.According to the invention, the peripheral edge BP is provided on its upper side CS with a so-called upper fixing tab PF1. Preferably, the peripheral edge BP is also provided on at least one of its two lateral sides CLi of at least one locking lug PCi. In the non-limiting example illustrated on the figures 2 and 3 , the peripheral edge BP is provided with a locking tab PCi on each of its two lateral sides CLi.

Par ailleurs, comme illustré sur les figures 4 à 6, la paroi avant PV du masque M est munie d'un moyen de fixation MF1. Lorsque le bord périphérique BP est muni sur au moins l'un de ses deux côtés latéraux CLi d'au moins une patte de calage PCi, alors la paroi avant PV du masque M est également munie d'au moins un moyen de calage MCi. Dans l'exemple non limitatif illustré sur les figures 4 à 6, la paroi avant PV est munie de deux moyens de calage MCi placés de part et d'autre de son moyen de fixation MF1.Moreover, as illustrated in Figures 4 to 6 the front wall PV of the mask M is provided with a fixing means MF1. When the peripheral edge BP is provided on at least one of its two lateral sides CLi of at least one locking lug PCi, then the front wall PV of the mask M is also provided with at least one wedging means MCi. In the non-limiting example illustrated on the Figures 4 to 6 , the front wall PV is provided with two setting means MCi placed on either side of its fixing means MF1.

Le moyen de fixation MF1 est destiné à coopérer avec la patte de fixation supérieure PF1 afin de fixer l'écran EC sur le masque M dans une position suspendue au niveau de son ouverture avant OA. Chaque éventuel moyen de calage MCi est destiné à coopérer avec la patte de calage PCi correspondante afin de caler latéralement l'écran EC par rapport au masque M.The fixing means MF1 is intended to cooperate with the upper fixing lug PF1 in order to fix the screen EC on the mask M in a suspended position at its front opening OA. Each possible setting means MCi is intended to cooperate with the corresponding clamping pad PCi in order to wedge laterally the screen EC with respect to the mask M.

En d'autres termes, dans le cas d'une double coopération l'écran EC est suspendu à la paroi avant PV du masque M, au niveau de l'ouverture avant OA, grâce à sa patte de fixation supérieure PF1, et calé latéralement grâce à sa (ses) patte(s) de calage PCi.In other words, in the case of a double cooperation, the screen EC is suspended from the front wall PV of the mask M, at the front opening OA, thanks to its upper fixing lug PF1, and wedged laterally. thanks to its leg (s) PCi calibration.

On notera qu'il est avantageux que la patte de fixation supérieure PF1 soit définie sensiblement au milieu du côté supérieur CS du bord périphérique BP de l'écran EC. Ce positionnement central est en effet optimal pour la suspension de l'écran EC dans la mesure où il lui assure un bon équilibre et évite qu'il subisse des rotations.It should be noted that it is advantageous for the upper fixing lug PF1 to be defined substantially in the middle of the upper side CS of the peripheral edge BP of the screen EC. This central positioning is indeed optimal for the suspension of the EC screen to the extent that it ensures a good balance and prevents it from being rotated.

Par ailleurs, il est également avantageux que la patte de fixation supérieure PF1 soit définie dans le prolongement du côté supérieur CS du bord périphérique BP (vers le haut) avec une légère inclinaison vers l'arrière (c'est-à-dire en direction de la face arrière de l'écran EC).Furthermore, it is also advantageous for the upper attachment lug PF1 to be defined in the extension of the upper side CS of the peripheral edge BP (upwards) with a slight inclination towards the rear (that is to say in the direction from the back of the EC screen).

Dans l'exemple de réalisation non limitatif illustré sur les figures 2 à 4, les deux pattes de calage PCi sont définies dans le prolongement des deux côtés latéraux CLi (vers le haut) sur des portions qui sont sensiblement dans la continuité du côté supérieur CS du bord périphérique BP. En d'autres termes les deux pattes de calage PCi sont érigées suivant une direction qui est approximativement la même que celle de la patte de fixation supérieure PF1. Mais cela n'est pas obligatoire. En effet, elles pourraient par exemple être érigées sur des portions des deux côté latéraux CLi qui sont approximativement perpendiculaires au côté supérieur CS, dès lors qu'elles ont pour fonction de positionner latéralement l'écran EC.In the nonlimiting exemplary embodiment illustrated on the Figures 2 to 4 , the two locking tabs PCi are defined in the extension of the two lateral sides CLi (upwards) on portions which are substantially in continuity with the upper side CS of the peripheral edge BP. In other words, the two chocks PCi are erected in a direction that is approximately the same as that of the upper bracket PF1. But this is not obligatory. Indeed, they could for example be erected on portions of the two lateral sides CLi which are approximately perpendicular to the upper side CS, since their function is to position the EC screen laterally.

Comme illustré non limitativement sur les figures 2 à 5, la patte de fixation supérieure PF1 peut par exemple comprendre une partie terminale libre qui est munie d'un ergot ER, de manière à permettre son clippage. Dans ce cas, et comme illustré non limitativement sur les figures 4 et 5, le moyen de fixation MF1 peut par exemple comprendre au moins un trou traversant TT défini dans la paroi avant PV et agencé de manière à recevoir et permettre le passage de l'ergot ER de la patte de fixation supérieure PF1.As illustrated without limitation on Figures 2 to 5 , the upper fixing lug PF1 may for example comprise a free end portion which is provided with a lug ER, so as to allow its clipping. In this case, and as illustrated in no way on the figures 4 and 5 , the fixing means MF1 may for example comprise at least one through hole TT defined in the front wall PV and arranged to receive and allow the passage of the lug ER of the upper bracket PF1.

Ce trou traversant TT est légèrement plus grand que la section de l'ergot ER pour une question de tolérance dimensionnelle.This through hole TT is slightly larger than the section of the ER pin for dimensional tolerance.

Cet ergot ER de la patte de fixation supérieure PF1 est préférentiellement orienté en direction de la face arrière FR de la paroi avant PV du masque M. Mais, une orientation opposée est également envisageable.This lug ER of the upper fixing lug PF1 is preferably oriented towards the rear face FR of the front wall PV of the mask M. But, an opposite orientation is also conceivable.

On notera, comme illustré non limitativement sur les figures 4 et 5, que le moyen de fixation MF1 peut également comprendre une saillie (ou un méplat ou encore une marche) SA au voisinage de son trou traversant TT, sur la face arrière FR de la paroi avant PV du masque M. Cette saillie SA comporte une face qui définit une surface d'appui pour l'ergot ER de la patte de fixation supérieure PF1. Cet ergot ER peut ainsi être clippé sur la saillie SA, après être passé au travers du trou traversant TT du moyen de fixation MF1 lors de la fixation de l'écran EC sur le masque M.It will be noted, as illustrated without limitation on the figures 4 and 5 that the fixing means MF1 may also comprise a projection (or a flat part or a step) SA in the vicinity of its through hole TT, on the rear face FR of the front wall PV of the mask M. This projection SA comprises a face which defines a bearing surface for the lug ER of the upper fixing lug PF1. This lug ER can thus be clipped onto the projection SA, after having passed through the through hole TT of the fastening means MF1 during the attachment of the screen EC on the mask M.

Comme illustré non limitativement sur les figures 4 et 6, chaque moyen de calage MCi peut comprendre au moins un trou traversant TT qui est défini dans la paroi avant PV du masque M et qui est destiné à recevoir et permettre le passage de la partie terminale (libre) de la patte de calage PCi correspondante. Ce trou traversant TT est légèrement plus grand que la section de la partie terminale (libre) de la patte de calage PCi pour une question de tolérance dimensionnelle et pour faciliter le calage latéral de l'écran EC.As illustrated without limitation on Figures 4 and 6 each clamping means MCi may comprise at least one through-hole TT which is defined in the front wall PV of the mask M and which is intended to receive and allow the passage of the end portion (free) of the corresponding locking lug PCi. This through-hole TT is slightly larger than the section of the terminal portion (free) of the calibration tab PCi for a question of dimensional tolerance and to facilitate the lateral setting of the EC screen.

La direction latérale est celle qui est sensiblement perpendiculaire à la direction d'érection de la patte de fixation supérieure PF1 et qui s'étend sensiblement entre les deux côtés latéraux CLi du bord périphérique BP.The lateral direction is that which is substantially perpendicular to the erection direction of the upper fixing lug PF1 and which extends substantially between the two lateral sides CLi of the peripheral edge BP.

Par ailleurs, et comme illustré non limitativement sur les figures 4 et 6, chaque moyen de calage MCi peut également comprendre deux protubérances PC définies sur la face arrière FR de la paroi avant PV du masque M, de part et d'autre de son trou traversant TT et l'une en face de l'autre. Ces deux protubérances PC peuvent être sensiblement identiques et sensiblement parallèles entre elles. Elles sont destinées à améliorer le calage latéral de l'écran EC par rapport au masque M, notamment au début de la phase de fixation.Moreover, and as illustrated in no way Figures 4 and 6 each setting means MCi may also comprise two PC protuberances defined on the rear face FR of the front wall PV of the mask M, on either side of its through hole TT and opposite each other. These two PC protuberances may be substantially identical and substantially parallel to each other. They are intended to improve the lateral setting of the EC screen with respect to the mask M, especially at the beginning of the fixing phase.

Dans une variante de réalisation (non représentée), les parties terminales libres des pattes de calage PCi peuvent également comporter des ergots. Mais dans ce cas, les moyens de calage MCi correspondant ne comprennent pas de paire de protubérances PC de part et d'autre de leur trou traversant TT. On notera que dans cette variante, il est préférable que le trou traversant TT de chaque moyen de calage MCi présente une dimension latérale sensiblement identique (par valeur supérieure) à celle de la patte de calage PCi correspondante (qui contribue alors à la fois au calage (ou positionnement) et à la fixation (clippage)).In an alternative embodiment (not shown), the free end portions of the locking lugs PCi may also include lugs. But in this case, the corresponding MCi wedging means do not include a pair of protuberances PC on either side of their through hole TT. Note that in this variant, it is preferable that the through hole TT of each wedging means MCi has a lateral dimension substantially identical (by a value greater) than that of the corresponding calibration pad PCi (which then contributes to both calibration). (or positioning) and fixing (clipping).

Comme illustré sur les figures 2, 3, 4, 7 et 9, afin de renforcer la fixation de l'écran EC sur le masque M, le bord périphérique BP de l'écran EC peut être également muni sur son côté inférieur CI d'une patte de fixation PF2 dite inférieure, destinée à coopérer avec un autre moyen de fixation MF2 défini dans une partie inférieure de la paroi arrière PR du masque M.As illustrated on figures 2 , 3 , 4 , 7 and 9 , in order to reinforce the fixing of the screen EC on the mask M, the peripheral edge BP of the screen EC may also be provided on its lower side CI with a lower PF2 fixing lug, intended to cooperate with another fixing means MF2 defined in a lower part of the rear wall PR of the mask M.

Cette patte de fixation inférieure PF2 permet non seulement d'immobiliser l'écran en partie inférieure, mais également de mettre sous contrainte la patte de fixation supérieure PF1 et les pattes de calage PCi. En outre elle permet d'éliminer les éventuels jeux entre le masque M et l'écran EC et donc d'éliminer les éventuels bruits et vibrations que ces jeux pourraient induire.This lower fixing lug PF2 not only makes it possible to immobilize the screen in the lower part, but also to put under stress the upper fixing lug PF1 and the lugs PCi. In addition, it eliminates possible gaps between the mask M and the EC screen and thus eliminate any noise and vibration that these games could induce.

On notera que lorsque l'écran EC présente des dimensions inférieures à celles de l'ouverture avant OA, il est avantageux que la patte de fixation inférieure PF2 soit définie à une extrémité du côté inférieur CI du rebord RB du bord périphérique BP de l'écran EC, comme illustré sur les figures 3, 4 et 9. Ce positionnement excentré (et sensiblement perpendiculaire à la paroi principale PP de l'écran EC) permet en effet de masquer efficacement la patte de fixation inférieure PF2 et le moyen de fixation MF2 associé.Note that when the EC screen has dimensions smaller than those of the front opening OA, it is advantageous that the leg of The lower fastening PF2 is defined at one end of the lower side CI of the edge RB of the peripheral edge BP of the screen EC, as illustrated in FIGS. figures 3 , 4 and 9 . This eccentric positioning (and substantially perpendicular to the main wall PP of the EC screen) makes it possible to effectively hide the lower fixing lug PF2 and the associated fixing means MF2.

Par ailleurs, il est également avantageux que la patte de fixation inférieure PF2 soit définie dans le prolongement du côté inférieur CI du bord périphérique BP avec une légère inclinaison vers le haut.Furthermore, it is also advantageous that the lower fixing lug PF2 is defined in the extension of the lower side CI of the peripheral edge BP with a slight upward inclination.

Comme illustré non limitativement sur les figures 3, 4 et 7, la patte de fixation inférieure PF2 peut par exemple comprendre une partie terminale libre qui est munie d'un ergot ER, de manière à permettre son clippage. Dans ce cas, et comme illustré non limitativement sur la figure 7, le moyen de fixation (inférieur) MF2 peut par exemple comprendre un trou traversant TT défini dans la paroi arrière PR et agencé de manière à recevoir et permettre le passage de l'ergot ER de la patte de fixation inférieure PF2.As illustrated without limitation on figures 3 , 4 and 7 , the lower bracket PF2 may for example comprise a free end portion which is provided with a lug ER, so as to allow its clipping. In this case, and as illustrated in a non-limiting manner on the figure 7 , the fixing means (lower) MF2 may for example comprise a through hole TT defined in the rear wall PR and arranged to receive and allow the passage of the lug ER of the lower bracket PF2.

Ce trou traversant TT est légèrement plus grand que la section de l'ergot ER pour une question de tolérance dimensionnelle.This through hole TT is slightly larger than the section of the ER pin for dimensional tolerance.

Cet ergot ER de la patte de fixation inférieure PF2 est préférentiellement orienté sensiblement parallèlement à la partie correspondante de la face arrière FR' de la paroi arrière PR du masque M.This lug ER of the lower fixing lug PF2 is preferably oriented substantially parallel to the corresponding portion of the rear face FR 'of the rear wall PR of the mask M.

On notera, comme illustré non limitativement sur la figure 7, que le trou traversant TT du moyen de fixation (inférieur) MF2 peut être défini dans une marche (ou un décrochement) MR de la paroi arrière PR dont la face par laquelle débouche l'ergot ER est sensiblement perpendiculaire à la partie de la face arrière FR'. Dans ce cas, la face de la marche MR qui est localement sensiblement parallèle à la partie locale de la face arrière FR' de la paroi arrière PR peut servir de surface d'appui pour l'ergot ER de la patte de fixation inférieure PF2. Cet ergot ER peut ainsi être clippé sur la marche MR, après être passé au travers du trou traversant TT du moyen de fixation (inférieur) MF2 lors de la phase finale de la fixation de l'écran EC sur le masque M. Comme illustré, il est avantageux que la partie terminale de la patte de fixation inférieure PF2 soit biseautée afin de faciliter le clippage de son ergot ER.It will be noted, as illustrated without limitation on the figure 7 , that the through hole TT of the fastening means (lower) MF2 can be defined in a step (or a recess) MR of the rear wall PR whose face through which the ER pin opens is substantially perpendicular to the part of the face rear FR '. In this case, the face of the MR step which is locally substantially parallel to the local portion of the rear face FR 'of the rear wall PR can serve as a bearing surface for the lug ER of the lower bracket PF2. This lug ER can thus be clipped onto the MR step, after having passed through the through hole TT of the fixing means (lower) MF2 during the final phase of fixing the EC screen on the mask M. As illustrated, it is advantageous for the end portion of the lower fixing lug PF2 to be beveled in order to facilitate the clipping of its lug ER.

La fixation de l'écran EC sur le masque M peut se dérouler comme indiqué ci-après. On commence par introduire les deux pattes de calage PC1 et PC2 dans les trous traversants TT des moyens de calage MC1 et MC2 correspondants. Ce calage permet de centrer l'écran EC et donc de faire passer l'ergot ER de la patte de fixation supérieure PF1 au travers du trou traversant TT du moyen de fixation MF1. L'ergot ER vient alors s'appuyer partiellement sur la face « supérieure » de la saillie SA du moyen de fixation MF1. Puis, en entraînant légèrement en rotation la partie inférieure de l'écran EC en direction du masque M, on vient clipper l'ergot ER de sa patte de fixation inférieure PF2 sur le moyen de fixation (inférieur) MF2 de la paroi arrière PR du masque M, permettant ainsi d'immobiliser l'écran EC tout en mettant sous contrainte la patte de fixation supérieure PF1 et les pattes de calage PC1 et PC2.The fixing of the EC screen on the mask M can proceed as indicated below. We begin by introducing the two clamping lugs PC1 and PC2 in the through holes TT corresponding timing means MC1 and MC2. This setting makes it possible to center the screen EC and thus to pass the lug ER of the upper fixing lug PF1 through the through hole TT of the fastening means MF1. The pin ER then comes to rest partially on the "upper" face of the projection SA of the fastening means MF1. Then, by slightly rotating the lower part of the screen EC in the direction of the mask M, the pin ER of its lower fixing lug PF2 is clipped onto the fixing means (lower) MF2 of the rear wall PR of the M mask, thus immobilizing the EC screen while putting under stress the upper bracket PF1 and the clamping lugs PC1 and PC2.
