DOSSIER RABATTABLE DE SIEGE ARRIERE D'UN VEHICULE
AUTOMOBILE
L'invention se rapporte à un appui-tete escamotable notamment pour dossier rabattable de siège arrière d'un véhicule automobile pourvu d'un support d'appui-tête et dont un axe d'articulation de l'appui-tete est solidaire dudit dossier; de sorte que l'appui-tête peut basculer d'une position d'utilisation jusqu'à une position de rannement contre la face arrière du dossier lorsque ce dernier est rabattu vers l'avant du véhicule.RETRACTABLE HEADREST, ESPECIALLY FOR A
FOLDING REAR SEAT BACK OF A VEHICLE
AUTOMOTIVE
The invention relates to a retractable headrest in particular for a folding rear seat backrest of a motor vehicle provided with a headrest support and of which an axis of articulation of the headrest is integral with said backrest ; so that the headrest can switch from a position of use to a stowing position against the rear face of the backrest when the latter is folded towards the front of the vehicle.
L'invention concerne plus particulièrement un tel appui-tete pour sièqes arrière des véhicules présentant un hayon ou une porte arrière facilitant le charçiement du plancher lorsque les sièges occupent une position escamotée.The invention relates more particularly to such a headrest for rear seats of vehicles having a tailgate or a rear door facilitating the loading of the floor when the seats occupy a retracted position.
Dans la plupart des véhicules de ce typez il n'est pas possible d'assurer une protection satisfaisante aux passagers des sièqes arrière lorsque le véhicule est heurté de l'arrière. En effet. ces sièqes ne possèdent généralement pas d'appuis-tetes. étant donné que ceux-ci rendraient difficile le ranqement du sièqe et l'aménagement de la surface de chargement.In most vehicles of this type, it is not possible to provide satisfactory protection for rear seat passengers when the vehicle is struck from the rear. Indeed. these seats generally do not have headrests. since these would make it difficult to stow the seat and arrange the loading surface.
Un certain nombre de tentatives ont été effectuées dans ce domaine La publication FR-A 2 441 512 décrit un appui-tete basculant dot le montant est inséré dans un manchon de quidaqe sur le bord supérieur du dossier de sièqe. Un tel appui-tête doit être retiré ou déplacé manuellement afin ou'il ne gêne Pas la visibilité et ne risque pas d'être endommaqé ou taché.A number of attempts have been made in this area. The publication FR-A 2 441 512 describes a tilting headrest dot the amount is inserted in a quidaqe sleeve on the upper edge of the seat back. Such a headrest must be removed or moved manually so that it does not interfere with visibility and is not likely to be damaged or stained.
La publication GB-A 2 069 328 décrit un appui-tête monté sur des bras pivotants a commande manuelle si peut être basculé vers une position de rangement au contact du dossier du sièqe lorsque celui-ci est rabattu vers l'avant:
La publication DE-A 2 757 188 décrit un appui-tete qui peut être monté sur le pavillon du véhicule et que l'on peut faire pivoter vers le haut. Il est toutefois difficile de réaliser un ancrage riqide sur le pavillon. Lorsqu'il a été relevé, cet appui-tête reste visible et peut gêner le charqement d'un colis volumineux.The publication GB-A 2 069 328 describes a headrest mounted on pivoting arms with manual control if it can be tilted to a storage position in contact with the seat back when the latter is folded forward:
Publication DE-A 2 757 188 describes a headrest which can be mounted on the roof of the vehicle and which can be pivoted upwards. It is however difficult to achieve a rigid anchoring on the roof. When raised, this headrest remains visible and may interfere with the loading of a large package.
La présente invention a pour but de réaliser un appui-tête de siège arri8re que l'on peut facilement placer dans une position escamotée dans un compartiment de chargement; qui peut facilement être monté sur un siège existant et être mis automatiquement en position d'utilisation par le passager qui veut utiliser le siège. The object of the present invention is to provide a rear seat headrest which can easily be placed in a retracted position in a loading compartment; which can easily be mounted on an existing seat and be automatically put in the use position by the passenger who wants to use the seat.
Un autre but de l'invention est la réalisation d'un appui-tête qui se place automatiquement dans une position escamotée au cours du déplacement du dossier du siège vers sa position de rangement.Another object of the invention is the production of a headrest which is automatically placed in a retracted position during the movement of the seat back towards its storage position.
Ce résultat est obtenu au moyen de la présente invention qui a pour objet un appui-tête escamotable notamment pour un dossier rabattable de siège arrière d'un véhicule automobile cc.nstitué notamment par un dossier rabattable vers l'avant. un support d 'appui-tete, un axe autorisant la rotation dudit support sur le dossier et un dispositif d'asservissement de la position de l'appui-tête par rapport audit axe de rotation.This result is obtained by means of the present invention which relates to a retractable headrest in particular for a folding backrest of the rear seat of a motor vehicle cc.nstitué in particular by a folding backrest forward. a headrest support, an axis allowing the rotation of said support on the backrest and a device for controlling the position of the headrest relative to said axis of rotation.
Selon l'invention, l'axe de rotation du support d'appui-tête est rigidement relié à un bras de commande dont l'extrémité libre porte une bielle de commande articulée; sensiblement parallèle au flanc du dossier et dont l'extrémité inférieure est articulée sur un élément inférieur qui supporte l'axe de rabattement du dossier.According to the invention, the axis of rotation of the headrest support is rigidly connected to a control arm whose free end carries an articulated control rod; substantially parallel to the side of the backrest and the lower end of which is articulated on a lower element which supports the axis of folding of the backrest.
Les caractéristiques et avantapes de l'invention ressortiront de la description qi va suivre d 'un mode de réalisation de l'appui-tête en référence au dessin annexé dans lequel - Les figures 1 et 2 sont des vues schématiques
analogues du mode d'implantation de l'appui-tête
sur un siège en position d'utilisation et de
rangement, - La figure 3 est une vue de face d'une armature de
dossier de siège portant le support d'appui-tête.The characteristics and steps of the invention will emerge from the description which will follow from an embodiment of the headrest with reference to the attached drawing in which - Figures 1 and 2 are schematic views
analogous to the way the headrest is installed
on a seat in the position of use and
storage, - Figure 3 is a front view of a frame of
seat back supporting the headrest support.
- La figure 4 est une vue en coupe transversale de
l'armature de dossier selon la liane 4-4 de la
foigure 3,
La fiaure 1 représente un sièoe arrière de véhicule a havon relevable dans la position d'utilisation.- Figure 4 is a cross-sectional view of
the back frame according to the liana 4-4 of the
foigure 3,
Figure 1 shows a rear seat of a liftable tailgate vehicle in the position of use.
La figure 2 représente ce meme sièoe dans la position de formation de la plage de charqement. Figure 2 shows the same seat in the position of formation of the loading range.
L'assise i du siège se relève vers l'avant indépendamment du déplacement du dossier 2 jusqu'à ce que l'assise 1 occupe une position relevée. Le dossier 2 peut etre rabattu vers le bas ainsi que représenté a la figure 2 dans le but de former une plage de chargement en prolongement du plancher 4 du véhicule.The seat i of the seat lifts forward independently of the movement of the backrest 2 until the seat 1 occupies a raised position. The backrest 2 can be folded down as shown in Figure 2 in order to form a loading area in extension of the floor 4 of the vehicle.
L'appui-tete 3 est représenté a la figure l dans sa position d'utilisation et à la fiqure 2 dans sa position escamotée.The headrest 3 is represented in FIG. 1 in its position of use and in FIG. 2 in its retracted position.
L'appui-tête amovible 3 est représenté par son support montré plus en détail a la figure 3.The removable headrest 3 is represented by its support shown in more detail in FIG. 3.
c'est-à-dire en position rapportée sur un élément d'armature du dossier 2 d'un sièqe arrière fractionné.that is to say in the position attached to a frame element of the backrest 2 of a split rear seat.
L'armature est représentée à la figure 3 par une plaque de fond 15 support du dossier 2.The frame is represented in FIG. 3 by a bottom plate 15 supporting the backrest 2.
La plaque de fond 15 porte par exemple un tube de rigidification 16 soudé le long du bord extérieur de la plaque 15. Celui-ci possède un tronçon supérieur 16s. deux tronçons latéraux 161 et une traverse inférieure 16i. Les tronçons latéraux 161 se pro longent vers le bas par des pieds 17. Chaque pied 17 est articulé autour d 'un axe 29 de rabattement du dossier sur une semelle. La semelle 18 intérieure et la semelle 19 extérieure sont fixées à un tube entretoise 20 de l'ensemble du dossier 2.The bottom plate 15 carries for example a stiffening tube 16 welded along the outer edge of the plate 15. The latter has an upper section 16s. two lateral sections 161 and a lower crosspiece 16i. The lateral sections 161 are extended downwards by feet 17. Each foot 17 is articulated around an axis 29 of folding the backrest on a sole. The inner sole 18 and the outer sole 19 are fixed to a spacer tube 20 of the entire backrest 2.
L'armature s'étend latéralement par un support d'enrouleur et par une aile 22 sur laquelle prend appui le coté du dossier 2. La partie supérieure de la plaque 15 porte les paliers d'articulation 23; 24, 25 de l'axe 26 du support 27 de l'appui-tete 3.The frame extends laterally by a reel support and by a wing 22 on which the side of the backrest 2 bears. The upper part of the plate 15 carries the articulation bearings 23; 24, 25 of the axis 26 of the support 27 of the headrest 3.
L'axe 26 s'étend vers le haut du dossier clans une échancrure 28 dans laquelle est loqé le support 27.The axis 26 extends towards the top of the backrest in a notch 28 in which the support 27 is latched.
Celui-ci porte deux douilles arretc.irs 30 dans lesquelles sont engagés des fourreaux plastiques 31 munis d'une tette de verrouillage 32 ainsi que cela est bien connu.It carries two arretc.irs sockets 30 in which are engaged plastic sleeves 31 provided with a locking plate 32 as is well known.
Les douilles 30 et les fourreaux 31 assurent le maintien et le guidage des pieds 33 de l'appui-tête 3. étant bien entendu que l'appui-tête peut posséder un pied central ou deux pieds tels que 33 situés de part et d'autre de l'axe médian de la plaque 15.The sockets 30 and the sleeves 31 maintain and guide the feet 33 of the headrest 3. it being understood that the headrest can have a central foot or two feet such as 33 located on either side other of the median axis of the plate 15.
Selon l'invention, la partie horizontale de l'axe 26 se prolonge extérieurement au palier 23 vers le bord de la plaque 15 par une extrémité applatie 26a.According to the invention, the horizontal part of the axis 26 extends externally to the bearing 23 towards the edge of the plate 15 by a flat end 26a.
Sur l'extrémité 26a de l'axe 26 est soudé un bras de commande 37 dont l'extrémité libre porte une bielle de commande 34 articulée autour d 'un axe 40 supérieur qui s'étend verticalement vers la base de la plaque 15 et est sensiblement parallèle au flanc du dossier 2. Cette mesure constructive permet de masquer l'ensemble des organes de commande de l'appui-tête dans le capitonnaae du dossier.On the end 26a of the axis 26 is welded a control arm 37 whose free end carries a control rod 34 articulated around an upper axis 40 which extends vertically towards the base of the plate 15 and is substantially parallel to the side of the backrest 2. This constructive measure makes it possible to hide all of the headrest control members in the backrest capitonnaae.
L'extrémité inférieure de la bielle 34 est articulée sur un flasque 35 autour d 'un axe 36 porté par l'extrémité applatie du tube entretoise 2( >
Le fonctionnement de l'appui-tête escamotable résulte de la description. En effet, lorsque l'on fait basculer le dossier 2 autour des axes 29 portés par l'une et l'autre semelle 18, 19, les distances inégales entre l'axe 26 du support 27 de l'appui-tête et l'axe d'articulation 40 de la bielle 34, d'une part et les distances de l'axe 36 d'articulation de la bielle 34 à l'axe 29 d'articulation du fond 15 d'autre part, sont inégales et engendrent un effort de traction ou de poussée sur l'axe 40 dans le sens d'une rotation de l'axe 26. Il en résulte que l'appui-tête tourne avec l'axe 26 dans un sens ou dans l'autre en fonction du sens de manoeuvre du dossier 2. The lower end of the connecting rod 34 is articulated on a flange 35 around an axis 36 carried by the flat end of the spacer tube 2 (>
The operation of the retractable headrest results from the description. Indeed, when the backrest 2 is tilted around the axes 29 carried by one and the other sole 18, 19, the unequal distances between the axis 26 of the support 27 of the headrest and the axis of articulation 40 of the connecting rod 34, on the one hand and the distances from the axis 36 of articulation of the connecting rod 34 to the axis 29 of articulation of the bottom 15 on the other hand, are unequal and generate a tensile or pushing force on the axis 40 in the direction of rotation of the axis 26. As a result, the headrest rotates with the axis 26 in one direction or the other depending on the direction of operation of the file 2.
