Description

L'invention concerne un essuie-glace de véhicule automobile comportant un témoin de vieillissement. The invention relates to a windscreen wiper for a motor vehicle comprising an aging indicator.

L'invention concerne plus particulièrement un essuie-glace de véhicule automobile du type comportant un balai d'essuie-glace qui est monté à l'extrémité libre d'un bras d'essuie-glace et qui plaque une raclette d'essuyage contre une vitre à essuyer. The invention relates more particularly to a wiper of a motor vehicle of the type comprising a wiper blade which is mounted at the free end of a wiper arm and which presses a wiper blade against a wiping glass.

Le balai d'essuie-glace est une pièce d'usure du véhicule qu'il est nécessaire de remplacer régulièrement si l'on veut garantir une bonne qualité d'essuyage de la vitre. Cela s'avère notamment particulièrement important pour la sécurité de conduite lorsqu'il s'agit d'un balai d'essuie-glace du pare-brise du véhicule. The wiper blade is a wearing part of the vehicle that must be replaced regularly if you want to guarantee good quality wiping of the window. This is particularly important for driving safety when it comes to a windscreen wiper blade.

Les sources de l'usure du balai sont nombreuses et celui-ci est susceptible de se dégrader tant au niveau de la raclette d'essuyage que de la monture articulée qui la porte. There are many sources of wear and tear on the broom, and it is likely to deteriorate both at the level of the wiper blade and of the articulated frame which carries it.

Par exemple, la raclette d'essuyage est susceptible de s'user par frottement mais elle peut également s'user du fait de l'altération du matériau qui la compose. For example, the wiping squeegee is susceptible to wear by friction but it can also wear due to the alteration of the material which composes it.

Un agent d'une telle altération est par exemple la lumière solaire, et tout particulièrement les rayonnements ultraviolets qu'elle contient. An agent of such an alteration is, for example, sunlight, and very particularly the ultraviolet radiation which it contains.

Toutefois, un agent particulièrement important d'altération du balai d'essuie-glace est tout simplement l'oxygène car, même si le véhicule stationne habituellement dans un garage fermé, donc à l'abri de la lumière, il ne peut être à l'abri de l'oxydation. However, a particularly important agent of deterioration of the wiper blade is quite simply oxygen because, even if the vehicle usually parked in a closed garage, therefore protected from light, it cannot be shelter from oxidation.

II apparaît particulièrement pertinent de déterminer la durée de vie du balai d'essuie-glace en fonction de son temps d'exposition à l'air et donc à l'oxygène. It appears particularly relevant to determine the life of the wiper blade as a function of its time of exposure to air and therefore to oxygen.

Par ailleurs, il est fréquent que les automobilistes soient incapables de se rappeler à quand remonte la dernière fois qu'ils ont procédé à l'échange de leurs balais d'essuie-glace. En effet, une telle opération n'est en général pas confiée à un spécialiste de la réparation automobile qui pourrait par exemple procéder à un remplacement systématique régulier des balais. In addition, it is common for motorists to be unable to remember when the last time they exchanged their wiper blades was. Indeed, such an operation is generally not entrusted to an automobile repair specialist who could for example carry out a regular systematic replacement of the brushes.

Aussi, dans le but de permettre à l'automobiliste de déterminer de manière très simple et peu coûteuse l'état de vieillissement des balais d'essuie-glace de son véhicule, I'invention propose un essuie-glace du type décrit précédemment, caractérisé en ce que l'essuie-glace est muni d'un témoin de vieillissement sensible à l'oxygène. Also, in order to allow the motorist to determine in a very simple and inexpensive manner the state of aging of the wiper blades of his vehicle, the invention proposes a wiper of the type described above, characterized in that the wiper is provided with an oxygen sensitive aging indicator.

Selon d'autres caractéristiques de l'invention
- le témoin de vieillissement est porté par le balai d'essuie glace
- le témoin de vieillissement incorpore une substance chimique réactive qui change de couleur en fonction de son degré d'oxydation
- la substance chimique réactive est un oxyde minéral, notamment un oxyde de titane
- le témoin de vieillissement comporte un film plastique qui est collé sur le balai et qui porte la substance chimique réactive
- il est prévu un dispositif de protection amovible qui isole le témoin de vieillissement de l'air ambiant et qui est retiré lors du montage du balai sur le véhicule.According to other features of the invention
- the aging indicator is carried by the wiper blade
- the aging indicator incorporates a reactive chemical which changes color depending on its degree of oxidation
- the reactive chemical substance is a mineral oxide, in particular a titanium oxide
- the aging indicator has a plastic film which is stuck on the brush and which carries the reactive chemical
- a removable protective device is provided which isolates the aging indicator from the ambient air and which is removed when the brush is mounted on the vehicle.

D'autres caractéristiques et avantages de l'invention apparaîtront à la lecture de la description détaillée qui suit pour la compréhension de laquelle on se reportera au dessin annexé dans lequel
- la figure 1 est une vue partielle en perspective d'un essuie-glace de véhicule automobile conforme aux enseignements de l'invention; ; et
- la figure 2 illustre de manière schématique un témoin de vieillissement selon l'invention.Other characteristics and advantages of the invention will appear on reading the detailed description which follows, for the understanding of which reference will be made to the appended drawing in which
- Figure 1 is a partial perspective view of a motor vehicle wiper according to the teachings of the invention; ; and
- Figure 2 schematically illustrates an aging control according to the invention.

On a représenté sur la figure 1 un essuie-glace 10 de véhicule automobile qui comporte essentiellement un bras d'essuieglace 12 à l'extrémité libre 14 duquel est monté articulé un balai d'essuie-glace 16. FIG. 1 shows a wiper 10 of a motor vehicle which essentially comprises a wiper arm 12 at the free end 14 of which is hinged a wiper blade 16.

Le balai d'essuie-glace 16 comporte une structure articulée 18 qui porte, par l'intermédiaire de griffes 20, une raclette d'essuyage 22 généralement réalisée en matériau élastomère souple. La structure articulée 18 est destinée à plaquer, sur toute sa longueur, la raclette d'essuyage 22 contre une vitre à essuyer du véhicule. The wiper blade 16 has an articulated structure 18 which carries, by means of claws 20, a wiping squeegee 22 generally made of flexible elastomeric material. The articulated structure 18 is intended to press, over its entire length, the wiping squeegee 22 against a window to be wiped from the vehicle.

Conformément aux enseignements de l'invention, le balai d'essuie-glace 16 porte un témoin de vieillissement 24 incorporant une substance chimique réactive qui possède la propriété de changer de couleur en fonction de son état d'oxydation par l'oxygène de l'air ambiant.  In accordance with the teachings of the invention, the wiper blade 16 carries an aging indicator 24 incorporating a reactive chemical substance which has the property of changing color as a function of its oxidation state by the oxygen of the ambiant air.

On pourra par exemple utiliser comme substance chimique réactive un oxyde minéral, notamment un oxyde de titane. We can for example use as reactive chemical a mineral oxide, in particular a titanium oxide.

Le témoin de vieillissement 24 pourra être également agencé en d'autres endroits de l'essuie-glace, pourvu qu'il soit aisément visible lorsque le balai d'essuie-glace 16 est monté sur le véhicule. The aging indicator 24 may also be arranged in other places of the wiper, provided that it is easily visible when the wiper blade 16 is mounted on the vehicle.

De préférence, le témoin de vieillissement est réalisé sous la forme d'une étiquette autocollante. II comporte un film support 26 en matière plastique, telle que le polyvinyle, le polyester ou le polypropylène, dont la face inférieure est enduite d'un adhésif à fort pouvoir adhérent qui permet d'assurer une fixation définitive fiable du témoin de vieillissement 24 sur le balai 16. Preferably, the aging indicator is produced in the form of a self-adhesive label. It comprises a support film 26 made of plastic, such as polyvinyl, polyester or polypropylene, the underside of which is coated with an adhesive with high adhesion which makes it possible to ensure reliable final fixing of the aging indicator 24 on the broom 16.

Le film support 26 porte une couche active 28 colorée dont la couleur est obtenue grâce à une substance chimique réactive susceptible d'exister sous plusieurs degrés d'oxydation, chaque degré d'oxydation conférant à la substance, et donc à la couche active 28 une coloration propre. The support film 26 carries a colored active layer 28 the color of which is obtained by virtue of a reactive chemical substance capable of existing under several degrees of oxidation, each degree of oxidation conferring on the substance, and therefore on the active layer 28 a clean coloring.

A la fabrication du témoin de vieillissement 24, la substance chimique réactive est incorporée dans la couche active 28 sous sa forme de degré d'oxydation le plus bas. During the manufacture of the aging control 24, the reactive chemical substance is incorporated into the active layer 28 in its form of lowest degree of oxidation.

Au cours du temps, I'oxygène de l'air, qui est au contact de la couche active ainsi fixée sur le balai 16, réagit avec la substance chimique réactive de manière que celle-ci s'oxyde pour atteindre son degré d'oxydation le plus haut. Over time, the oxygen in the air, which is in contact with the active layer thus fixed on the brush 16, reacts with the reactive chemical substance so that it oxidizes to reach its degree of oxidation the highest.

On a avantage à choisir une substance chimique réactive dont la coloration soit plus intense lorsqu'elle est sous sa forme de plus bas degré d'oxydation. Ainsi, la perception du changement de couleur du témoin de vieillissement 24 sera plus nette et ne se fera que lorsque la quasi totalité de la réaction d'oxydation de cette substance sera terminée. It is advantageous to choose a reactive chemical whose coloring is more intense when it is in its form of lower degree of oxidation. Thus, the perception of the change in color of the aging indicator 24 will be clearer and will only take place when almost all of the oxidation reaction of this substance has been completed.

Eventuellement, afin de mieux contrôler la cinétique de la réaction d'oxydation, on pourra avoir intérêt à superposer sur la couche active une couche de diffusion qui ralentit le contact entre la substance chimique réactive et l'oxygène. Optionally, in order to better control the kinetics of the oxidation reaction, it may be advantageous to superimpose on the active layer a diffusion layer which slows down the contact between the reactive chemical substance and oxygen.

Enfin, on peut prévoir de recouvrir le témoin de vieillissement 24 d'un film protecteur 30 qui isole la couche active 28 de l'oxygène tant que le balai d'essuie-glace 16 n'est pas en place sur le véhicule. Ce film protecteur 30 est alors destiné à être retiré au moment du montage du balai 16 sur le véhicule.  Finally, provision can be made to cover the aging indicator 24 with a protective film 30 which isolates the active layer 28 from oxygen as long as the wiper blade 16 is not in place on the vehicle. This protective film 30 is then intended to be removed when the brush 16 is mounted on the vehicle.
