Description

L'invention concerne un élément d'habillage d'une tôle de plancher d'habitacle de véhicule automobile et des architectures de montage d'un tel élément. The invention relates to a covering element of a vehicle cabin floor plate and mounting architectures of such an element.

Il est connu de réaliser un élément d'habillage d'une tôle de plancher d'habitacle de véhicule automobile, ledit élément comprenant une armature à base de matériau moulé, ladite armature comprenant un plateau pourvu de moyens de piètement, tels que des nervures ou des pieds, issus de matière de son envers, ledit matériau étant à base de matériau thermoplastique injecté, tel que du polypropylène. It is known to produce a covering element of a motor vehicle cabin floor plate, said element comprising a frame based on molded material, said frame comprising a plate provided with base means, such as ribs or feet, derived from its backing material, said material being based on injected thermoplastic material, such as polypropylene.

Un tel élément, couramment appelé « faux plancher », a pour fonction de créer un sol sensiblement plat, notamment pour des véhicules de type « monospace ». Such an element, commonly called "false floor", has the function of creating a substantially flat floor, especially for vehicles type "minivan".

L'utilisation d'un tel matériau présente plusieurs inconvénients : • les outillages et presses de moulage par injection sont complexes et coûteux, • l'armature présente un poids important, en raison de la densité du matériau utilisé, • du fait de la rigidité intrinsèque du matériau, les vibrations de la tôle de plancher sont retransmises de façon importante par l'armature, ce qui oblige à disposer une couche d'amortissement, telle que du feutre, entre la tôle et les moyens de piètement, • toujours du fait de la rigidité du matériau, il est généralement nécessaire de disposer une couche de confort élastiquement compressible entre le plateau et une couche de revêtement dudit plateau, telle qu'une moquette, ceci afin de procurer un confort d'approche aux occupants du véhicule, ce qui complexifie la réalisation. The use of such a material has several disadvantages: • tools and injection molding presses are complex and expensive, • the frame has a significant weight, because of the density of the material used, • because of the rigidity intrinsic material, the vibrations of the floor plate are transmitted significantly by the armature, which requires to have a cushioning layer, such as felt, between the sheet and the base means, • always because the rigidity of the material, it is generally necessary to have an elastically compressible comfort layer between the plate and a coating layer of said tray, such as a carpet, in order to provide comfort of approach to the occupants of the vehicle, which complicates the realization.

L'invention a pour but de pallier ces inconvénients. The invention aims to overcome these disadvantages.

A cet effet, et selon un premier aspect, l'invention propose un élément d'habillage d'une tôle de plancher d'habitacle de véhicule automobile, ledit 2 élément comprenant une armature à base de matériau moulé, ladite armature comprenant un plateau pourvu de moyens de piètement issus de son envers, ledit matériau étant à base de mousse de polyuréthanne élastiquement compressible. For this purpose, and according to a first aspect, the invention proposes a covering element of a motor vehicle cabin floor plate, said element comprising a frame based on molded material, said frame comprising a plate provided with base means from its back, said material being based on elastically compressible polyurethane foam.

L'utilisation d'un tel matériau permet de s'affranchir efficacement des inconvénients de l'art antérieur en termes de simplification des outillages, d'allègement, de réduction de la transmission des vibrations de la tôle de plancher et de confort d'approche, et ceci tout conservant une portance suffisante pour limiter l'enfoncement sous le poids des passagers, comme on le verra plus loin. The use of such a material makes it possible to overcome effectively the drawbacks of the prior art in terms of simplification of tools, lightening, reduction of the transmission of vibrations of the floor plate and comfort of approach , and this all maintaining sufficient lift to limit the sink under the weight of passengers, as discussed below.

Selon un deuxième aspect, l'invention propose des architectures de montage d'un tel élément. D'autres particularités et avantages de l'invention apparaîtront dans la description qui suit, faite en référence à la figure jointe qui est une représentation schématique partielle en coupe d'un élément posé sur une tôle de plancher. 20 En référence à la figure, on décrit un élément 1 d'habillage d'une tôle 2 de plancher d'habitacle de véhicule automobile, ledit élément comprenant une armature 3 à base de matériau moulé, ladite armature comprenant un plateau 4 pourvu de moyens de piètement 5, notamment sous forme de pieds ou de 25 nervures, issus de son envers, ledit matériau étant à base de mousse de polyuréthanne élastiquement compressible. According to a second aspect, the invention proposes architectures for mounting such an element. Other features and advantages of the invention will become apparent in the description which follows, made with reference to the attached figure which is a partial schematic representation in section of an element placed on a floor plate. Referring to the figure, there is described an element 1 for covering a motor vehicle cabin floor plate 2, said element comprising a frame 3 based on molded material, said armature comprising a plate 4 provided with means 5, in particular in the form of feet or ribs, from its underside, said material being based on elastically compressible polyurethane foam.

Selon une réalisation, la mousse de polyuréthanne présente une densité comprise entre 0,025 et 0,040, ce qui permet un allègement considérable de 30 l'élément 1, malgré une augmentation éventuelle d'épaisseur, sachant que les matériaux utilisés dans l'art antérieur, tels que le polypropylène, peuvent présenter une densité proche de 1.15 3 Selon une réalisation, la mousse de polyuréthanne présente une portance comprise entre 35 KPa et 60 KPa pour une compression de 50%. According to one embodiment, the polyurethane foam has a density of between 0.025 and 0.040, which allows a considerable lightening of the element 1, despite a possible increase in thickness, knowing that the materials used in the prior art, such as polypropylene may have a density close to 1.15. According to one embodiment, the polyurethane foam has a lift of between 35 KPa and 60 KPa for a compression of 50%.

Une telle portance permet d'obtenir une bonne résistance de l'armature 3 sous le poids des passagers. Such a lift makes it possible to obtain good strength of the frame 3 under the weight of the passengers.

Selon une réalisation, la mousse de polyuréthanne présente une résilience comprise entre 12% et 15%. In one embodiment, the polyurethane foam has a resilience of between 12% and 15%.

Selon la réalisation représentée, l'élément 1 comprend en outre une couche de revêtement 6, notamment à base de moquette, posée sur le plateau 4. According to the embodiment shown, the element 1 further comprises a coating layer 6, in particular based on carpet, placed on the plate 4.

On notera dans la réalisation représentée l'absence de couche de confort élastique compressible, telle que du feutre, entre le plateau 4 et la couche de revêtement 6, la souplesse de la mousse de polyuréthanne étant généralement suffisante pour assurer cette fonction de confort d'approche. It will be noted in the embodiment shown the absence of compressible elastic comfort layer, such as felt, between the plate 4 and the coating layer 6, the flexibility of the polyurethane foam being generally sufficient to ensure this comfort function of approach.

Une telle couche de confort, qui peut être surmoulée par la mousse de polyuréthanne, peut toutefois être prévue dans les cas où l'on souhaite optimiser le confort d'approche. Such a comfort layer, which can be overmolded by the polyurethane foam, may however be provided in cases where it is desired to optimize the comfort of approach.

Selon la réalisation représentée, l'élément comprend en outre une couche élastiquement compressible d'amortissement 7, notamment à base de feutre, ladite couche recouvrant les moyens de piétement 5 et étant surmoulée par la mousse de polyuréthanne. According to the embodiment shown, the element further comprises an elastically compressible damping layer 7, in particular based on felt, said layer covering the base means 5 and being overmolded by the polyurethane foam.

Ceci étant, une telle couche d'amortissement est facultative, la souplesse de la mousse de polyuréthanne étant suffisante pour permettre, même en l'absence de couche d'amortissement 7, une atténuation significative des vibrations de la tôle 2. This being so, such a damping layer is optional, the flexibility of the polyurethane foam being sufficient to allow, even in the absence of damping layer 7, significant damping of the vibrations of the sheet 2.

On décrit à présent, comme représenté sur la figure, une architecture où les moyens de piétement 5 sont posés sur la tôle 2 de plancher de l'habitacle du véhicule automobile par l'intermédiaire de la couche d'amortissement 6, une telle réalisation étant mise en oeuvre dans le cas où l'on souhaite optimiser la réduction de transmission des vibrations de ladite tôle. An architecture is now described, as represented in the figure, in which the base means 5 are placed on the floor plate 2 of the passenger compartment of the motor vehicle by means of the damping layer 6, such an embodiment being implementation in the case where it is desired to optimize the vibration transmission reduction of said sheet.

En variante non représentée, une architecture de montage d'un élément 1 peut prévoir que les moyens de piétement 5 sont directement posés contre la tôle 2 de plancher de l'habitacle du véhicule automobile, la souplesse du matériau permettant, malgré l'absence de couche d'amortissement 7 une réduction significative de la transmission des vibrations de la tôle 2.10 In a variant that is not shown, an architecture for mounting an element 1 may provide that the support means 5 are directly placed against the floor plate 2 of the passenger compartment of the motor vehicle, the flexibility of the material permitting, in spite of the absence of damping layer 7 a significant reduction of the vibration transmission of the sheet 2.10
