Abstract

The flap comprises a rigid body (1) defining a panel (4, 5) on one face of which a foam seal (9) is elastically compressed by a bearing element (10). Along the edge of the panel there extends a marginal region (11) of the seal, which region is not covered by the bearing element, and which deforms and exhibits great flexibility allowing defects in flatness of a sealing wall with which the flap interacts to be compensated for. Application to vehicle heating/ventilation or air-conditioning units.

Description

Volet pivotant pour appareil de chauffage ou de climatisation de véhicule
L'invention concerne un volet pivotant, en particulier pour la commande d'un débit d'air dans un appareil de chauffage/ ventilation ou de climatisation de véhicule, comprenant un corps rigide définissant une plaque sur une face au moins de laquelle est appliqué, le long de son bord, un joint en un matériau propre à se déformer élastiquement sous pression avec réduction d'épaisseur, destiné à venir en contact étanche avec la paroi d'une conduite d'air.Pivoting shutter for vehicle heating or air conditioning
The invention relates to a pivoting shutter, in particular for controlling an air flow rate in a vehicle heating / ventilation or air conditioning device, comprising a rigid body defining a plate on at least one face of which is applied, along its edge, a seal made of a material capable of deforming elastically under pressure with reduction in thickness, intended to come into tight contact with the wall of an air duct.

Les parois des conduites d'air présentent fréquemment des défauts de planéité ou des formes irrégulières, dues notamment aux dépouilles de démoulage, aux retraits de moulage, et/ou aux défauts d'alignement de différents éléments de boîtier. Pour assurer l'étanchéité avec une telle paroi irrégulière, il est connu de munir le joint d'une lèvre souple faisant saillie au-delà du bord libre de la plaque.The walls of the air ducts frequently have flatness defects or irregular shapes, due in particular to mold stripping, molding shrinkage, and / or misalignment of different housing elements. To seal with such an irregular wall, it is known to provide the seal with a flexible lip projecting beyond the free edge of the plate.

Mais l'entrée en contact de cette lèvre avec la paroi est bruyante. De plus, lorsque la lèvre s'étend sensiblement selon le plan de la plaque, les possibilités de rattrapage sont limitées. Celles-ci peuvent être améliorées en inclinant la lèvre par rapport au plan de la plaque, mais des difficultés interviennent alors pour la flexion de la lèvre dans les angles du volet.But the coming into contact of this lip with the wall is noisy. In addition, when the lip extends substantially along the plane of the plate, the possibilities of catching up are limited. These can be improved by tilting the lip relative to the plane of the plate, but difficulties then arise for the bending of the lip in the angles of the flap.

Le but de l'invention est de remédier à ces inconvénients.The object of the invention is to remedy these drawbacks.

L'invention vise notamment un volet du genre défini en introduction, et prévoit que le joint comporte une première région serrée, avec réduction d'épaisseur, sur'ladite face de la plaque par un élément d'appui, et une seconde région adjacente à la première, située au-delà de l'élément d'appui vers l'extérieur de la surface de la plaque.The invention relates in particular to a shutter of the kind defined in the introduction, and provides that the seal comprises a first tight region, with reduction in thickness, on the said face of the plate by a support element, and a second region adjacent to the first, located beyond the support element towards the outside of the surface of the plate.

D'autres caractéristiques, complémentaires ou alternatives, de l'invention sont énoncées ci-après - La plaque s'étend vers l'extérieur au-delà de l'élément d'appui pour soutenir la seconde région du joint.Other characteristics, complementary or alternative, of the invention are set out below - The plate extends outwards beyond the support element to support the second region of the joint.

- La seconde région du joint s'étend vers l'extérieur au-delà du bord de la plaque.- The second region of the joint extends outward beyond the edge of the plate.

- Le joint est en mousse.- The seal is made of foam.

- La mousse est à pores fermés, ou est recouverte d'une peau au moins sur la région de sa surface venant en contact avec la paroi de la conduite d'air, de façon à assurer l'etan- chéité de ce contact.- The foam is closed pore, or is covered with a skin at least on the region of its surface coming into contact with the wall of the air duct, so as to ensure the tightness of this contact.

- Le corps, le joint et l'élément d'appui sont assemblés entre eux par des moyens mécaniques.- The body, the seal and the support element are assembled together by mechanical means.

Les caractéristiques et avantages de l'invention seront exposés plus en détail dans la description ci-après, en se référant aux dessins annexés, sur lesquels - la figure 1 est une vue en plan d'un volet selon l'invention; et - la figure 2 est une vue en bout de ce volet, selon la direction de son axe de pivotement.The characteristics and advantages of the invention will be explained in more detail in the description below, with reference to the accompanying drawings, in which - Figure 1 is a plan view of a shutter according to the invention; and - Figure 2 is an end view of this component, in the direction of its pivot axis.

Le volet illustré comprend un corps 1 en une seule pièce moulée en polypropylène chargé présentant une poutre 2 allongée selon l'axe de pivotement 3 du volet, et deux ailes 4 et 5 en forme de plaques planes s'étendant sensiblement radialement à partir de la poutre. La poutre 2 est prolongée à ses deux extrémités par des embouts 6 propres à coopérer avec le boîtier d'un appareil de chauffage ou de climatisation pour le guidage du volet en pivotement autour de l'axe 3, et avec des organes d'entraînement pour le mouvement de pivotement.The illustrated flap comprises a body 1 in a single molded piece of charged polypropylene having a beam 2 elongated along the pivot axis 3 of the flap, and two wings 4 and 5 in the form of flat plates extending substantially radially from the beam. The beam 2 is extended at its two ends by end pieces 6 capable of cooperating with the housing of a heating or air conditioning device for guiding the flap in pivoting about the axis 3, and with drive members for the pivoting movement.

Des nervures de raidissement 7 sont formées sur l'une des faces de chacune des ailes 4 et 5, et des picots 8 font saillie sur les faces opposées de celles-ci. Une feuille 9 de mousse plastique compressible élastiquement et une plaque plane rigide 10, toutes deux percées d'ouvertures pour le passage des picots 8, sont appliquées sur ladite face opposée de chacune des ailes.Stiffening ribs 7 are formed on one of the faces of each of the wings 4 and 5, and pins 8 protrude from the opposite faces of the latter. A sheet 9 of resiliently compressible plastic foam and a rigid flat plate 10, both pierced with openings for the passage of the pins 8, are applied to said opposite face of each of the wings.

Chacune des ailes 4 et 5 a une forme sensiblement polygonale (dans l'exemple particulier rectangulaire pour l'aile 4 et trapézoïdale pour l'aile 5) dont l'un des cotés est adjacent à la pouture, les autres côtés définissant un bord libre de l'aile. La feuille 9 recouvre toute la surface de l'aile et s'étend légèrement au-delà de celle-ci sur toute la longueur de son bord libre. Au contraire, la plaque 10 laisse une région marginale de l'aile, et par conséquent une région marginale 11 de la feuille 9, découverte sur toute la longueur du bord libre.Each of the wings 4 and 5 has a substantially polygonal shape (in the particular example rectangular for the wing 4 and trapezoidal for the wing 5) one of the sides of which is adjacent to the beam, the other sides defining a free edge of the wing. The sheet 9 covers the entire surface of the wing and extends slightly beyond it over the entire length of its free edge. On the contrary, the plate 10 leaves a marginal region of the wing, and consequently a marginal region 11 of the sheet 9, uncovered over the entire length of the free edge.

Lors de l'assemblage du volet, chacune des plaques 10 est fixée, par rivetage à chaud au moyen des picots 8, en comprimant élastiquement la feuille 9 de façon à réduire son épaisseur. Cette compression entraîne une déformation de la région marginale 11, celle-ci étant déviée angulairement dans un sens opposé à l'aile 4 ou 5. Cette déformation augmente la souplesse de cette région marginale et lui permet de compenser des irrégularités de surface importantes de la paroi de la conduite, sans qu'il soit nécessaire d'exercer un effort mécanique élevé sur le volet et sans que celui-ci produise de bruit de claquement.During assembly of the shutter, each of the plates 10 is fixed, by hot riveting by means of the pins 8, by compressing elastically the sheet 9 so as to reduce its thickness. This compression causes a deformation of the marginal region 11, the latter being angularly deflected in a direction opposite to the wing 4 or 5. This deformation increases the flexibility of this marginal region and allows it to compensate for significant surface irregularities of the wall of the pipe, without it being necessary to exert a high mechanical force on the flap and without it producing a clicking noise.

Bien entendu, l'invention n'est pas limitée à des volets dont le corps comporte deux ailes en forme de plaques tel que celui décrit ci-dessus. Elle s'applique tout aussi bien dans le cas d'un corps de volet à une seule aile. De plus, des joints et des éléments d'appui peuvent être prévus sur les deux faces d'une même aile du corps pour assurer l'étanchéité aux deux extrémités de la course du volet.Of course, the invention is not limited to shutters, the body of which has two plate-shaped wings such as that described above. It applies equally well in the case of a flap body with a single wing. In addition, seals and support elements may be provided on the two faces of the same wing of the body to ensure sealing at the two ends of the flap stroke.

Bien qu'il soit avantageux que le joint s'étende sur toute la surface de la plaque du corps, ce qui facilite sa fabrica tion, il est également possible, selon l'invention, de découper le joint sous forme d'une bande s'étendant le long du bord libre de la plaque. Although it is advantageous for the joint to extend over the entire surface of the body plate, which facilitates its manufacture, it is also possible, according to the invention, to cut the joint in the form of a strip s extending along the free edge of the plate.
