Description

Soufflet de garnissage intérieur de véhicule automobileMotor vehicle interior trim bellows

L’invention concerne un soufflet de garnissage intérieur de véhicule automobile et un ensemble de masquage comprenant un tel soufflet.The invention relates to a motor vehicle interior trim gaiter and a masking assembly comprising such a gaiter.

Il est connu de réaliser un soufflet de garnissage intérieur de véhicule automobile, ledit soufflet étant à base d’un format de feuille souple, ledit format étant refermé sur lui-même de manière à présenter une forme générale de manchon pourvu d’une ouverture supérieure et d’une ouverture inférieure.It is known to produce a motor vehicle interior trim bellows, said bellows being based on a flexible sheet format, said format being closed on itself so as to have the general shape of a sleeve provided with an upper opening. and a lower opening.

Avec un tel agencement, on observe que, lorsque le véhicule est exposé à des températures très basses – par exemple de l’ordre de -30°C –, la feuille peut finir par présenter un aspect craquelé, ce qui est esthétiquement préjudiciable.With such an arrangement, it is observed that, when the vehicle is exposed to very low temperatures – for example of the order of -30° C. –, the sheet may end up having a cracked appearance, which is aesthetically detrimental.

Un tel inconvénient se rencontre notamment quand la feuille comprend une nappe textile enduite d’une couche d’aspect en matériau thermoplastique, ou encore une couche de cuir.Such a drawback is encountered in particular when the sheet comprises a textile ply coated with an appearance layer of thermoplastic material, or even a layer of leather.

Et le fait que le soufflet soit à base de matériau souple amené à être déformé de façon répétée ne fait qu’accentuer le problème.And the fact that the bellows is made of flexible material that is subject to repeated deformation only accentuates the problem.

Par ailleurs, on peut observer une rigidification du soufflet exposé à de très basses températures.Furthermore, stiffening of the bellows exposed to very low temperatures can be observed.

L’invention a pour but de pallier ces inconvénients.The object of the invention is to overcome these drawbacks.

A cet effet, et selon un premier aspect, l’invention propose un soufflet de garnissage intérieur de véhicule automobile, ledit soufflet étant à base d’un format de feuille souple, ledit format étant refermé sur lui-même de manière à présenter une forme générale de manchon pourvu d’une ouverture supérieure et d’une ouverture inférieure, ladite feuille étant pourvue sur sa face d’envers d’un circuit électrique résistif de chauffage à base d’encre conductrice imprimée, les extrémités dudit circuit étant pourvues de bornes de connexion à un générateur électrique.To this end, and according to a first aspect, the invention proposes a motor vehicle interior trim bellows, said bellows being based on a flexible sheet format, said format being closed on itself so as to present a shape general sleeve provided with an upper opening and a lower opening, said sheet being provided on its back face with a resistive electric heating circuit based on printed conductive ink, the ends of said circuit being provided with terminals connection to an electric generator.

Dans cette description, les termes de positionnement dans l’espace (supérieur, inférieur,…) sont pris en référence au soufflet monté dans le véhicule.In this description, the terms of positioning in space (upper, lower, etc.) are taken in reference to the bellows mounted in the vehicle.

Avec l’agencement proposé, on dispose d’un soufflet pouvant être chauffé par le circuit électrique en cas d’exposition du véhicule à de très basses températures.With the proposed arrangement, there is a bellows which can be heated by the electrical circuit in the event of exposure of the vehicle to very low temperatures.

Le chauffage peut notamment être déclenché de manière automatique en cas d’atteinte d’une température seuil prédéfinie.In particular, the heating can be triggered automatically if a predefined threshold temperature is reached.

Le fait de réaliser le circuit à base d’encre conductrice imprimée permet au soufflet de conserver sa souplesse et de ne pas présenter de gêne pour l’utilisateur d’un organe d’actionnement, tel qu’un levier de vitesse ou de frein à main, mis en interface avec ledit soufflet.The fact of making the circuit based on printed conductive ink allows the bellows to retain its flexibility and not to present any inconvenience to the user of an actuating member, such as a gear or brake lever. hand, interfaced with said bellows.

Selon un deuxième aspect, l’invention propose un ensemble de masquage comprenant un tel soufflet.According to a second aspect, the invention proposes a masking assembly comprising such a bellows.
