Description

La présente invention se rapporte aux sièges, notamment aux sièges de véhicules automobiles, et plus particulièrement aux sièges baquets de toute sorte. Pour améliorer le confort des fauteuils et sièges de véhicules, on a proposé de former des supports latéraux tant au dossier qu'au placet du siège pour que l'usager soit bien maintenu en place même dans le virages pris à vive allure.The present invention relates to seats, in particular to motor vehicle seats, and more particularly to bucket seats of all kinds. To improve the comfort of armchairs and vehicle seats, it has been proposed to form lateral supports both in the backrest and in the seatplate so that the user is well held in place even when cornering at high speed.

Dans certains sièges baquets actuels, ces supports latéraux sont réalisés par le rembourrage et/ ou le garnissage des sièges. L'inconvénient de cette façon de faire réside dans l'affaissement progressif, relativement rapide, de ces supports ce qui en réduit l'effet de maintien.In certain current bucket seats, these lateral supports are produced by padding and / or lining the seats. The drawback of this way of doing things lies in the relatively rapid progressive collapse of these supports, which reduces the holding effect.

Le brevet US-A-3 411 824 décrit un siège baquet comprenant un cadre inférieur supportant un fond comportant un diaphragme élastique présentant une partie centrale et des ailes formant un angle avec cette partie centrale. Ce diaphragme présente des organe d'ancrage en vue de sa fixation au cadre et est destiné à recevoir un rembourrage. Une telle construction ne permet pas non plus d'éviter un affaissement progressif dû au vieillissement des caractéristiques élastiques du diaphragme et au tassement du rembourrageUS-A-3 411 824 describes a bucket seat comprising a lower frame supporting a bottom comprising an elastic diaphragm having a central part and wings forming an angle with this central part. This diaphragm has anchoring members for attachment to the frame and is intended to receive padding. Such a construction also does not make it possible to avoid a progressive collapse due to the aging of the elastic characteristics of the diaphragm and to the packing of the padding.

Le siège baquet selon la présente invention tend à remédier aux inconvénients précités et se distinque par les caractéristiques énumérées à la revendication 1.The bucket seat according to the present invention tends to remedy the aforementioned drawbacks and is distinguished by the characteristics listed in claim 1.

Le dessin annexé illustre schématiquement et à titre d'exemple deux formes d'exécution du siège baquet selon l'invention.

  • La figure 1 est une vue schématique du principe de construction d'un siège de véhicule automobile.
  • La figure 2 illustre une plate-forme servant d'armature à la partie centrale du dossier respectivement du placet du siège baquet selon l'invention.
  • La figure 3 illustre en coupe la fixation de la plate-forme au cadre mètallique du siège.
  • La figure 4 illustre un autre mode de fixation de la plate-forme au cadre du siège.
The accompanying drawing illustrates schematically and by way of example two embodiments of the bucket seat according to the invention.
  • Figure 1 is a schematic view of the principle of construction of a motor vehicle seat.
  • FIG. 2 illustrates a platform serving as a frame for the central part of the back respectively of the bucket seat placet according to the invention.
  • Figure 3 illustrates in section the attachment of the platform to the metal frame of the seat.
  • Figure 4 illustrates another method of attaching the platform to the seat frame.

Le fauteuil ou siège baquet selon l'invention est illustré schématiquement à la figure 1, il se compose d'un cadre inférieur 1 horizontal et d'un cadre supérieur 2, formant le dossier du siège, articulé sur le cadre inférieur 1. Ces cadres 1 et 2 sont généralement métalliques et réalisés par des pièces embouties, des profilés ou des éléments tubulaires.The armchair or bucket seat according to the invention is illustrated schematically in Figure 1, it consists of a horizontal lower frame 1 and an upper frame 2, forming the seat back, articulated on the lower frame 1. These frames 1 and 2 are generally metallic and produced by stamped parts, profiles or tubular elements.

Les surfaces portantes du siège, fond et dossier sont généralement constituées par des plate-formes 3 reliées aux cadres respectifs 1,2 à l'aide de ressorts. Cet ensemble constitue L'armature portante du siège qui reçoit ensuite le garnissage et le rembourrage en mousse plastique par exemple recouverte de tissus ou simili-cuir, afin de .donner au siège son apparence extérieure.The bearing surfaces of the seat, bottom and backrest generally consist of platforms 3 connected to the respective frames 1,2 by means of springs. This assembly constitutes the carrying frame of the seat which then receives the upholstery and the padding in plastic foam, for example covered with fabrics or imitation leather, in order to give the seat its external appearance.

Généralement les plate-formes 3 sont réalisées en fils métalliques, treillis, plaques de matière plastique, etc. et présentent une forme générale plane.Generally the platforms 3 are made of metal wires, mesh, plastic plates, etc. and have a generally planar shape.

Il existe également des sièges baquets dont la plate-forme est réalisée par un diaphragme en caoutchouc, donc élastique, présentant une partie centrale plane bordée d'un fil de fer et des ailes tendues sur des armatures.There are also bucket seats whose platform is made by a rubber diaphragm, therefore elastic, having a flat central part bordered by a wire and wings stretched over frames.

Au contraire de ces plate-formes planes existantes le siège baquet selon l'invention comporte des plate-formes rigides 3 présentant une surface centrale 4 approximativement plane bordée sur deux côtés de rebords ou ailes 5 situées dans des plans formant un angle avec la partie centrale 4 pour donner à la plate-forme une forme générale de gouttière. Dans l'exemple illustré, ces plate-formes en forme de gouttière sont réalisées en matière plastique moulée ou injectée, elles peuvent être pleines ou ajourées comme illustré.Unlike these existing flat platforms, the bucket seat according to the invention comprises rigid platforms 3 having an approximately flat central surface 4 bordered on two sides with flanges or wings 5 situated in planes forming an angle with the central part. 4 to give the platform a general gutter shape. In the example illustrated, these gutter-shaped platforms are made of molded or injected plastic, they can be solid or perforated as illustrated.

Les plate-formes monolithiques en forme de gouttière 4,5 comportent des organes d'ancrage 6 reliés à l'aide de ressorts 7 aux cadres 2 ou 1 du siège. La rigidité ou la souplesse désirée du siège est obtenue par ajustage d'une part de la rigidité des plate-formes 4, 5 elles-mêmes et d'autre part par la force des ressorts 7.The monolithic platforms in the form of a gutter 4.5 comprise anchoring members 6 connected by means of springs 7 to the frames 2 or 1 of the seat. The desired stiffness or flexibility of the seat is obtained by adjusting on the one hand the rigidity of the platforms 4, 5 themselves and on the other hand by the force of the springs 7.

De cette façon la forme en baquet ou cuvette du fond et du dossier du siège est déjà donnée par les plate-formes, et non pas seulement par le rembourrage, de sorte que tout affaissement est évité.In this way the shape of the bottom and back of the seat in a tub or bowl is already given by the platforms, and not only by the padding, so that any sagging is avoided.

Pour renforcer la rigidité des ailes 5 des plate-formes 3, les organes d'ancrage 6 peuvent comporter des nervures 8 (figure 3).To reinforce the rigidity of the wings 5 of the platforms 3, the anchoring members 6 may include ribs 8 (FIG. 3).

Dans la forme d'exécution illustrée à la figure 4, les ressorts 7 sont montés directement dans les organes d'ancrage 6 de la plate-forme 4,5.In the embodiment illustrated in FIG. 4, the springs 7 are mounted directly in the anchoring members 6 of the platform 4,5.

Il est évident que la plate-forme décrite en forme de gouttière pourrait être réalisée en tôle étampée et pliée, ou tout autre matériau adéquat.It is obvious that the platform described in the form of a gutter could be made of stamped and folded sheet metal, or any other suitable material.

Dans une variante, le siège pourrait ne comporter qu'une plate-forme en forme de gouttière, formant le dossier ou le fond.In a variant, the seat could have only one platform in the form of a gutter, forming the backrest or the bottom.

De même les ressorts 7 peuvent être remplacés par tout organe élastique, bandes ou boucles en caoutchouc par exemple.Likewise, the springs 7 can be replaced by any elastic member, rubber bands or loops for example.

Dans la réalisation du siège selon l'invention il est important que la ou les plate-formes soient réalisées en un matériau relativement rigide pouvant être flexible mais en aucun cas extensible élastiquement pour garantir le maintien de la forme désirée du siège baquet.In the embodiment of the seat according to the invention it is important that the platform or platforms are made of a relatively rigid material which can be flexible but in no case elastically extensible to guarantee the maintenance of the desired shape of the bucket seat.
