Il est connu de réaliser des sur-tapis, dont la fonction principale est de protéger le tapis de sol d'un véhicule automobile, en particulier dans la zone en contact avec les pieds des passagers.  It is known to make mattresses, whose main function is to protect the floor of a motor vehicle, especially in the area in contact with the feet of passengers.

De tels sur-tapis, pour assurer leur fonction de protection de façon optimale, et lo aussi pour garantir une non interférence avec les pédales de commande du véhicule à l'emplacement du conducteur, doivent être fixés contre le tapis à protéger.  Such mats, to ensure their optimum protection function, and lo also to ensure non-interference with the vehicle's control pedals at the driver's location, must be fixed against the carpet to be protected.

A cette fin, il a été proposé que les sur-tapis soient pourvus d'organes de 15 fixation destinés à être solidarisés à des organes complémentaires intégrés dans l'environnement du sur-tapis, par exemple au tapis.  To this end, it has been proposed that the mats be provided with fixing members intended to be secured to complementary members integrated in the environment of the mat, for example carpet.

En outre, il est connu d'intégrer à de tels sur-tapis un dispositif d'échange thermique, tel qu'une résistance électrique destinée à procurer un chauffage radiatif du véhicule par le sol, ledit dispositif étant alimenté par une source d'alimentation périphérique, non intégrée au surtapis, telle qu'un alternateur.  In addition, it is known to integrate in such sur-mats a heat exchange device, such as an electrical resistance for providing a radiative heating of the vehicle by the ground, said device being powered by a power source peripheral, not integrated into the mat, such as an alternator.

II se pose alors le problème d'assurer une connexion fiable entre le dispositif d'échange thermique et sa source d'alimentation, par exemple électrique, et de garantir sa fiabilité pendant la durée de vie du véhicule, et ceci malgré les démontages répétés des sur-tapis en vue de procéder à leur nettoyage.  There then arises the problem of ensuring a reliable connection between the heat exchange device and its power source, for example electrical, and to guarantee its reliability during the lifetime of the vehicle, and this despite the repeated disassembly of on-carpet to clean them.

L'invention a pour but de proposer une connexion sécurisée et fiable, compatible avec les contraintes de démontage sus-évoquées.  The object of the invention is to propose a secure and reliable connection, compatible with the aforementioned disassembly constraints.

A cet effet, et selon un premier aspect, l'invention propose un système d'échange thermique par le sol d'un véhicule automobile, le dit système comprenant: É un sur-tapis destiné à être destiné à être fixé sur un tapis de sol, comprenant des organes de fixation et un dispositif d'échange thermique; É des organes de fixation complémentaires; s É une source d'alimentation dudit dispositif d'échange thermique; ledit système présentant les caractéristiques suivantes: É les organes de fixation sont connectés au dispositif d'échange thermique; É les organes de fixation complémentaires sont connectés à la source i0 d'alimentation; É lesdits organes de fixation sont connectés de façon réversible aux organes de fixation complémentaires de sorte à permettre une connexion dudit dispositif d'échange thermique à ladite source d'alimentation.  For this purpose, and according to a first aspect, the invention proposes a system for heat exchange by the ground of a motor vehicle, said system comprising: an over-carpet intended to be fixed on a carpet of floor, comprising fixing members and a heat exchange device; É additional fasteners; a power source of said heat exchange device; said system having the following characteristics: E the fasteners are connected to the heat exchange device; The complementary fasteners are connected to the supply source; Said fasteners are reversibly connected to the complementary fasteners so as to allow a connection of said heat exchange device to said power source.

On assure de la sorte une connexion simple et fiable du dispositif à la source d'alimentation, ceci du fait qu'elle se fait directement par association des organes de fixation aux organes complémentaires lors de la fixation du sur-tapis sur le tapis.  This ensures a simple and reliable connection of the device to the power source, this is because it is done directly by association of the fasteners to the complementary members when fixing the carpet on the mat.

Les organes de fixation complémentaires peuvent être intégrés au tapis de sol ou être situés dans l'environnement de celui-ci.  The complementary fasteners can be integrated in the floor mat or be located in the environment of the latter.

Les organes de fixation peuvent former avec les organes complémentaires des 30 clips, réalisés en matériau conducteur, ce qui permet un démontage aisé du sur-tapis tout en assurant une connexion fiable. i0  The fasteners can form with the complementary members clips made of conductive material, which allows easy disassembly of the carpet while ensuring a reliable connection. i0

Selon une réalisation, le dispositif d'échange thermique comprend au moins un canal agencé pour pouvoir véhiculer un fluide, liquide ou gazeux, destiné à être porté à la température requise par la source d'alimentation, les organes de fixation formant avec les organes complémentaires une connexion étanche permettant la circulation dudit fluide.  According to one embodiment, the heat exchange device comprises at least one channel arranged to be able to convey a fluid, liquid or gaseous, intended to be brought to the temperature required by the power source, the fixing members forming with the complementary members a sealed connection for the circulation of said fluid.

La circulation d'un tel fluide peut être envisagée à des fins de chauffage ou de refroidissement du véhicule, ceci selon la température relative du fluide par rapport à la température ambiante.  The circulation of such a fluid can be considered for heating or cooling the vehicle, this according to the relative temperature of the fluid relative to the ambient temperature.

II peut être envisagé l'utilisation de canaux très fins, de type caloducs , présentant des performances intéressantes dans ce type d'application, la source d'alimentation pouvant être un système réfrigérant le fluide utilisé.  It can be envisaged the use of very thin channels, type heat pipes, with interesting performance in this type of application, the power source can be a refrigerant system the fluid used.
