Description

REPOSE-TETE A COUSSIN D'APPUI MOBILE POUR VEHICULES
AUTOMOBILES
L'invention concerne un repose-tête à coussin d'appui mobile pour véhicules automobiles, comportant une armature par rapport à laquelle est susceptible de se déplacer le dit coussin.MOBILE SUPPORT CUSHION FOR VEHICLES
AUTOMOBILES
The invention relates to a headrest with a mobile support cushion for motor vehicles, comprising a frame relative to which said cushion is capable of moving.

La publication FR-A-2302705 décrit un repose-tête dont le coussin mobile est guidé le long d'une tige le positionnement raccordée aux pieds de montage du repose-tête sur un dossier de siège de véhicule automobile.The publication FR-A-2302705 describes a headrest whose movable cushion is guided along a rod the positioning connected to the mounting feet of the headrest on a seat back of a motor vehicle.

La publication US-A-2306334 décrit un repose-tête orientable dont le coussin est guidé le long d'une glissière de positionnement.The publication US-A-2306334 describes an adjustable headrest whose cushion is guided along a positioning slide.

Lorsque l'utilisateur du repose-tête est retenu sur son siège au moyen de ceintures de sécurité, la position de confort de la tête s'accompagne d'un déplacement latéral du tronc. La réduction conséquente d'efficacité de la ceinture est alors préjudiciable à la sécurité de l'utilisateur.When the user of the headrest is retained on his seat by means of seat belts, the position of comfort of the head is accompanied by a lateral displacement of the trunk. The consequent reduction in the effectiveness of the belt is therefore detrimental to the safety of the user.

L'invention se propose de remédier à l'inconvénient précité et a pour objet un repose-tête à coussin mobile monté à déplacement le long d'une glissière fixe, dans le but d'obtenir un appui latéral compatible avec la position de la tête de l'occupant du siège.The invention proposes to remedy the aforementioned drawback and relates to a headrest with a movable cushion mounted to move along a fixed slide, with the aim of obtaining a lateral support compatible with the position of the head. of the seat occupant.

L'invention a également pour objet un repose-tête comportant un élément mobile destiné à soutenir le côté de la tête de l'occupant d'un siège en position de repos.The invention also relates to a headrest comprising a movable element intended to support the side of the head of the occupant of a seat in the rest position.

Selon l'invention la glissière de positionnement du coussin d'appui mobile est so]idaire d'un élément fixe du repose-tête et possède des' moyens de guidage courbes d'un profil de guidage porté par ledit coussin d'appui.According to the invention the positioning slide of the movable support cushion is so] idaire of a fixed element of the headrest and has' curved guide means of a guide profile carried by said support cushion.

D'autres caractéristiques et avantages du repose-tête apparaîtront à la lecture de la description d'un exemple de réalisation de celui-ci, faite en référence du dessin annexé dans lequel - la figure 1 est une représentation en position d'utilisation du repose-tête
monté sur un siège de véhicule automobile, - la figure 2 est une vue en coupe transversale du repose-tête, - la figure 3 est une vue en coupe agrandie de la fixation du tissu de
revêtement du repose-tête sur le coussin d'appui.Other characteristics and advantages of the headrest will become apparent on reading the description of an exemplary embodiment thereof, given with reference to the appended drawing in which - FIG. 1 is a representation in the position of use of the headrest -head
mounted on a motor vehicle seat, - Figure 2 is a cross-sectional view of the headrest, - Figure 3 is an enlarged sectional view of the attachment of the fabric
covering of the headrest on the support cushion.

Ainsi que cela est montré au dessin, le dossier 10 d'un siège de passager de véhicule porte un repose-tête 11 muni d'une armature de support matérialisée par des pieds de montage 12. L'armature de support est entourée par un coussin fixe 13 dont la face avant porte une glissière 15 courbe de positionnement. La glissière 15 est formée ainsi que cela est montré à la figure 3 sur une plaque de guidage courbe 16 solidaire du coussin 13 dont la concavité est tournée vers un coussin d'appui mobile 14. Le dos du coussin 14, tourne vers le coussin fixe 13, porte également un profil de guidage 17 courbe, solidaire d'une plaque homologue 16' dont la configuration permet l'encastrement dudit profil 17 dans la glissière 15.A cet effet la glissière 15 et le profil 17 sont formés par les rainures de guidage parallèles de réception de nervures de guidage, mutuellement en contact par encastrement des formes conjuguées, des sections correspondantes de la glissière 15 et du profil 17. L'une des plaques 16 ou 16' possède par ailleurs une fente transversale 26 dont les bords constituent la butée d'un pion 28 porté par l'autre plaque 16' ou 16 dans le but de limiter les déplacements transversaux relatifs du coussin mobile 14 par rapport au coussin fixe 13.As shown in the drawing, the backrest 10 of a vehicle passenger seat carries a headrest 11 provided with a support frame materialized by mounting feet 12. The support frame is surrounded by a cushion fixed 13 whose front face carries a slide 15 positioning curve. The slide 15 is formed as shown in FIG. 3 on a curved guide plate 16 integral with the cushion 13 whose concavity is turned towards a movable support cushion 14. The back of the cushion 14, turns towards the fixed cushion 13, also carries a curved guide profile 17, integral with a homologous plate 16 ′ whose configuration allows the embedding of said profile 17 in the slide 15. To this end the slide 15 and the profile 17 are formed by the grooves parallel guide for receiving guide ribs, mutually in contact by embedding of the conjugated shapes, of the corresponding sections of the slide 15 and of the profile 17. One of the plates 16 or 16 ′ moreover has a transverse slot 26 whose edges constitute the stop of a pin 28 carried by the other plate 16 ′ or 16 in order to limit the relative transverse displacements of the movable cushion 14 relative to the fixed cushion 13.

Ainsi que cela est montré au dessin, le coussin fixe 13 et le coussin d'appui mobile 14 sont constitués par des matelassure de mousse 30, 30' sur lesquelles sont respectivement rapportées les plaques 16, 16'. Chacune des plaques porte par ailleurs des rainures de montage 32, 32', des bordures du tissu de revêtement 31, immobilisées par des baguettes de coincement 33. As shown in the drawing, the fixed cushion 13 and the movable support cushion 14 are constituted by foam padding 30, 30 'on which the plates 16, 16' are respectively attached. Each of the plates also carries mounting grooves 32, 32 ′, edges of the covering fabric 31, immobilized by wedging rods 33.
