Abstract
Description
La présente invention est relative aux pavillons de véhicules, du type comportant un panneau en matière plastique fixé par ses bords à un cadre supérieur de la structure du véhicule. et recouvert d'une garniture sur sa face inférieure. Cette garniture est généralement réalisée en matière plastique plus ou moins souple et maintenue appliquée sur le panneau par collage ou par un moyen élastique. The present invention relates to vehicle pavilions, of the type comprising a plastic panel fixed by its edges to an upper frame of the vehicle structure. and covered with a trim on its underside. This lining is generally made of more or less flexible plastic and kept applied to the panel by gluing or by elastic means.
Pour atténuer les bruits perçus dans l'habitacle du véhicule. il est usuel de prévoir un espace. To reduce the noise perceived in the passenger compartment of the vehicle. it is usual to provide a space.
donc une couche d'air. entre le panneau et la garniture, et de réaliser celle-ci en un matériau perméable à l'air. Cette disposition implique la presence, entre le panneau et la garniture, de pièces formant entretoises telles que de minces traverses solidaires de la structure et servant d'appui à la garniture.so a layer of air. between the panel and the lining, and to make the latter in an air-permeable material. This arrangement implies the presence, between the panel and the lining, of parts forming spacers such as thin cross-pieces secured to the structure and serving to support the lining.
Suivant une autre réalisation, cette garniture est relativement rigide et fixée par son pourtour au cadre. sans prendre appui sur le panneau; la garniture est alors relativement lourde, ce qui nécessite une fixation appropriée plus compliquée et encombrante qu'un simple collage. According to another embodiment, this lining is relatively rigid and fixed by its periphery to the frame. without leaning on the panel; the lining is then relatively heavy, which requires an appropriate fixing which is more complicated and bulky than a simple bonding.
On connait aussi des panneaux en matière plastique constitués d'au moins deux parois entre lesquelles est interposée au moins une feuille ondulée qui rigidifie le panneau tout en maintenant entre les parois opposées un volume d'air susceptible d'atténuer la réflexion de vibrations sonores. Plastic panels are also known which consist of at least two walls between which there is interposed at least one corrugated sheet which stiffens the panel while maintaining between the opposite walls a volume of air capable of attenuating the reflection of sound vibrations.
Ces diverses dispositions sont relativement coûteuses et délicates à réaliser. These various arrangements are relatively expensive and difficult to carry out.
L'invention a pour but d'aménager sur un véhicule un pavillon qui soit simple et qui présente de bonnes caractéristiques de rigidité et d'absorption des sons dans 1 habitacle
L'invention concerne un pavillon du type susmentionné, caractérisé en ce que le panneau est réalisé par moulage et comporte sur sa face inférieure des nervures sensiblement verticales, tandis que la garniture, perméable à l'air, est collée sur le bord inférieur des nervures.The object of the invention is to provide a vehicle which is simple and has good rigidity and sound absorption characteristics in 1 cabin.
The invention relates to a pavilion of the aforementioned type, characterized in that the panel is produced by molding and has substantially vertical ribs on its underside, while the air-permeable lining is glued to the lower edge of the ribs. .
Selon quelques caractéristiques avantageuses de l'invention
- il est prévu des nervures longitudinales et des nervures transversales s'étendant les unes sur toute la longueur du pavillon et les autres sur toute sa largeur;
- le panneau est réalisé en mousse de polyuréthane chargée deverre, et son moulage est effectué par expansion.According to some advantageous features of the invention
- There are provided longitudinal ribs and transverse ribs extending one over the entire length of the pavilion and the other over its entire width;
- The panel is made of polyurethane foam loaded with glass, and its molding is carried out by expansion.
Un exemple de réalisation d'un pavillon de véhicule est décrit ci-apres. avec référence au dessin annexé dont la Figure unique représente la partie supérieure d'un véhicule équipé du pavillon. vue en coupe par un plan vertical transversal, c'est-à-dire perpendiculaire à la direction longitudinale du véhicule. An exemplary embodiment of a vehicle roof is described below. with reference to the accompanying drawing, the single figure of which represents the upper part of a vehicle fitted with the roof. sectional view through a transverse vertical plane, that is to say perpendicular to the longitudinal direction of the vehicle.
On voit sur cette Figure deux parties la térales opposées la, lb d'un cadre supérieur 1 de la structure du véhicule. We see in this Figure two opposite parts the la, lb of an upper frame 1 of the vehicle structure.
Sur le bord interne supérieur de ce cadre est fixé par collage un panneau 2 en matière plastique muni, sur sa face inférieure, de nervures sensiblement verticales 3a, 3b respectivement longitudinales et transversales et s'étendant les unes sur toute la longueur du panneau, et les autres sur toute sa largeur. On the upper internal edge of this frame is fixed by bonding a plastic panel 2 provided on its underside with substantially vertical ribs 3a, 3b respectively longitudinal and transverse and extending one over the entire length of the panel, and the rest over its entire width.
En variante, les nervures ou certaines nervures sont orientées suivant des directions obliques par- rapport à la direction longitudinale du véhicule. As a variant, the ribs or certain ribs are oriented in oblique directions relative to the longitudinal direction of the vehicle.
La hauteur des nervures est par exemple de l'ordre d'un ou deux centimètres, et sur leur bord inférieur est collée une garniture 4 dont les bords 4a, 4b prennent appui sur la partie interne inférieure du cadre 1. The height of the ribs is for example of the order of one or two centimeters, and on their lower edge is bonded a lining 4 whose edges 4a, 4b are supported on the lower internal part of the frame 1.
Le panneau 2 et la garniture 4 constituent le pavillon du véhicule. The panel 2 and the trim 4 constitute the roof of the vehicle.
Le panneau 2 est réalisé en mousse de polyuréthane chargée de verre, par une opération de moulage par expansion. Ce matériau et le réseau de nervures croisées procurent au panneau la légèreté et la rigidité requises notamment dans les véhicules automobiles. The panel 2 is made of polyurethane foam filled with glass, by an expansion molding operation. This material and the network of crossed ribs provide the panel with the lightness and rigidity required in particular in motor vehicles.
La garniture 4 est réalisée en une matière plastique usuelle légèrement souple et perméable à l'air. Cette perméabilité, associée à la présence de chambres 5 emplies d'air délimitées entre les nervures 3a, 3b, par le panneau 2 et la garniture 4. procure un effet acoustique atténuant les bruits perçus dans l'habitacle situé sous le pavillon 2, s. The lining 4 is made of a conventional plastic material which is slightly flexible and breathable. This permeability, associated with the presence of chambers 5 filled with air delimited between the ribs 3a, 3b, by the panel 2 and the lining 4. provides an acoustic effect attenuating the noise perceived in the passenger compartment located under the roof 2, s .
