Abstract
Description
Appui -t ête escamotable notamment de siège arrière de véhicule automobile. Support -t retractable head including rear seat of a motor vehicle.
L'invention se rapporte à un appui-tête escamotable de siège dont le dossier est pourvu d'un support d'appui-tête et où un axe d'articulation de l'appui-tête est solidaire dudit support, de sorte que l'appui-tête peut basculer d'une position d'utilisation jusqu'à une position de rangement contre la face arrière du dossier lorsque ce dernier est rabattu vers l'avant du véhicule.The invention relates to a retractable seat headrest, the backrest of which is provided with a headrest support and where an axis of articulation of the headrest is integral with said support, so that the headrest can switch from a position of use to a storage 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-tête pour sièges arrière des véhicules présentant un hayon ou une porte arrière facilitant le chargement 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 type, il n'est pas possible d'assurer une protection satisfaisante aux passagers des sièges arrière lorsque le véhicule est heurté de l'arrière. En effet, ces sièges ne possèdent généralement pas d'appuis-tête, étant donné que ceux-ci rendraient difficile le rangement du siège 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. In fact, these seats generally do not have head restraints, since these would make it difficult to store the seat and arrange the loading surface.
Un certain nombre de tentatives ont été effectuées dans ce domaine.A number of attempts have been made in this area.
On a utilisé des appuis-tête conventionnels dont les montants sont insérés dans des manchons de guidage sur le bord supérieur du dossier de siège. Un tel appui-tête doit être retiré ou déplacé afin qu'il ne gêne la visibilité et ne risque d'être endommagé ou taché.Conventional head restraints have been used, the uprights of which are inserted into guide sleeves on the upper edge of the seat back. Such a headrest must be removed or moved so that it does not obstruct visibility and cannot be damaged or stained.
Une autre solution consiste à conférer au bord supérieur du dossier une mobilité verticale pour le transformer en appui-tête. Cette manière de procéder affaiblit la traverse supérieure de l'armature du dossier.Another solution is to give the upper edge of the backrest vertical mobility to transform it into a headrest. This procedure weakens the upper cross member of the back frame.
Cette manière de procéder rend également plus compliqué l'habillage du dossier du siège et a pour effet d'offrir un moins bon soutien à la partie supérieure du dos En outre, ce type d'appui-tête ne peut pas être monté en option sur un siège existant
On a aussi mis au point des appuis-tête qui peuvent être montés sur le pavillon du véhicule et que l'on peut faire pivoter vers lehauto
Il est toutefois difficile de réaliser un ancrage rigide sur le pavillon Lorsqu'ils ont été relevés, ces appuis-tête restent visibles et peuvent gêner le chargement d'un colis volumineux
La présente invention a pour but de réaliser un appui-tête de siège arrière que l'on peut facilement placer dans une position de formation d'un compartiment utilitaire, dans laquelle il est complètement escamoté, qui peut facilement être monté sur un siège existant et qui peut être mis en position d'utilisation, par le passager qui veut utiliser le siège.This procedure also makes it more complicated to cover the seat back and has the effect of providing less support for the upper back. In addition, this type of headrest cannot be fitted as an option on an existing headquarters
We have also developed headrests which can be mounted on the roof of the vehicle and which can be pivoted towards the auto
It is however difficult to achieve a rigid anchorage on the roof When they have been raised, these head restraints remain visible and can hinder the loading of a bulky package
The present invention aims to provide a rear seat headrest which can easily be placed in a position for forming a utility compartment, in which it is completely retracted, which can easily be mounted on an existing seat and which can be 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 dont le support et le corps de l'appui-tête portent des organes de verrouillage et de déverrouillage coopérants de sorte que le corps de l'appui-tête peut basculer d'une position d'utilisation jusqu'à une position pliée au dessus du dossier du siège lorsque ce dernier est rabattu vers l'avant.This result is obtained by means of the present invention, which relates to a headrest, the support and the body of the headrest of which carry cooperating locking and unlocking members so that the body of the headrest can switch from a position of use to a folded position above the seat back when the seat is folded forward.
Les caractéristiques et avantages de l'invention ressortiront de la description qui 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'utili
sation et de rangement - la figure 3 est une vue en coupe transversale de l'appui-tête selon
un plan de coupe brisé passant par le pied et les organes de verrouillage.The characteristics and advantages of the invention will emerge from the description which follows of an embodiment of the headrest with reference to the appended drawing in which - Figures 1 and 2 are diagrammatic views similar to the mode
to install the headrest on a seat in the use position
sation and storage - Figure 3 is a cross-sectional view of the headrest according
a broken section plane passing through the foot and the locking members.
La figure 1 représente un siège arrière de véhicule à hayon relevable dans la position d'utilisation, tel que représenté dans la demande de brevet français 80/12 269, déposé au nom de la demanderesse. Figure 1 shows a rear seat of a liftgate vehicle in the position of use, as shown in French patent application 80/12 269, filed in the name of the applicant.
La figure 2 représente ce même siège dans la position de formation de la plage de chargement.FIG. 2 represents this same seat in the position of formation of the loading area.
L'assise 1 du siège se relève vers l'avant sous l'action de déplacement du dossier 2 jusqu'à ce que l'assise l occupe une position relevée et que le dossier 2 soit rabattu vers le bas ainsi que représenté à la figure 2.The seat 1 of the seat lifts forward under the action of moving the backrest 2 until the seat l occupies a raised position and the backrest 2 is folded down as shown in the figure 2.
L'appui-tête 3 est représenté à la figure 1 dans sa position d'utilisation et à la figure 2 dans sa position de rangement.The headrest 3 is shown in Figure 1 in its position of use and in Figure 2 in its storage position.
L'appui-tête amovible 3 est représenté plus en détail à la figure 3 c'est-à-dire en position rapportée sur l'armature du dossier 4 du siège.The removable headrest 3 is shown in more detail in FIG. 3, that is to say in the position attached to the frame of the backrest 4 of the seat.
L'armature est représentée sur le dessin par la traverse supérieure 5 du dossier et par une douille 6. La douille 6 est coiffée par un fourreau plastique 7 munie d'une tête de verrouillage 8 tournante ainsi que cela est bien connu. Le fourreau 7 et la douille 6 assurent le maintien et le guidage d'un pied 9 de l'appui-tête, étant bien entendu que l'appui-têtepeut posséderunpied central ou deux pieds tels que 9 situés de part et d'autre de son plan de symétrie longitudinal.The frame is shown in the drawing by the upper cross member 5 of the backrest and by a sleeve 6. The sleeve 6 is capped by a plastic sleeve 7 provided with a rotating locking head 8 as is well known. The sheath 7 and the socket 6 maintain and guide a foot 9 of the headrest, it being understood that the headrest can have a central foot or two feet such as 9 located on either side of its longitudinal plane of symmetry.
Les pieds 9 sont rigidement reliés à un support 10 constitué par un assemblage d'éléments définissant un plateau Il dans lequel s'encastre le soubassement 12 portant l'axe d'articulation 13 du corps 14 de 1 'appui-tête. The feet 9 are rigidly connected to a support 10 constituted by an assembly of elements defining a plate II in which the base 12 is fitted, carrying the articulation axis 13 of the body 14 of the headrest.
Selon l'invention, le support 10 et le corps 14 de l'appui-tête portent des organes de verrouillage et de déverrouillage coopérants de sorte que le corps de l'appui-tête peut basculer d'une position d'utilisation représentée à la figure I jusqu'à une position pliée au dessus du dossier 2 du siège lorsque ce dernier est rabattu vers l'avant comme représenté à la figure 2.According to the invention, the support 10 and the body 14 of the headrest carry cooperating locking and unlocking members so that the body of the headrest can tilt from a position of use shown in the FIG. 1 to a folded position above the seat back 2 when the latter is folded forward as shown in FIG. 2.
Selon le mode de réalisation décrit à la figure 3, les organes de verrouillage et de déverrouillage sont principalement constitués par un rouleau 15 dont les extrémités sont guidées le long de rampes parallèles 16 constituées par assemblage du plateau 11 et du soubassement 12.According to the embodiment described in FIG. 3, the locking and unlocking members are mainly constituted by a roller 15, the ends of which are guided along parallel ramps 16 formed by assembling the plate 11 and the base 12.
Les rampes 16 sont inclinées vers l'arrière du support 10 et reçoivent la masse d'inertie constituée par le rouleau guidé 15.The ramps 16 are inclined towards the rear of the support 10 and receive the mass of inertia constituted by the guided roller 15.
La partie médiane du rouleau 15 forme le pène de retenue d'un crochet 17 intégré au corps 14 de l'appui-tête.The middle part of the roller 15 forms the retaining bolt of a hook 17 integrated into the body 14 of the headrest.
Le corps 14 peut être constitué par une armature en tôle ou plastique à élémentsassemblés ainsi que référencée en 18 à la figure 3 Sans sortir du cadre de l'invention, il est bien évident que l'appui-tête amovible, conforme à l'invention, peut également équiper un siège avant de véhicule automobile susceptible d'occuper une position d'utilisation et une position basculée facilitant la montée et la descente des passagers des places arrières. The body 14 may be constituted by a sheet or plastic frame with assembled elements as referenced at 18 in FIG. 3 Without departing from the scope of the invention, it is quite obvious that the removable headrest, in accordance with the invention , can also be fitted to a front seat of a motor vehicle capable of occupying a position of use and a tilted position facilitating the ascent and descent of rear seat passengers.
Un ressort peut aisément être incorporé à l'axe d'articulation 13 pour ramener automatiquement l'appui-tête à sa position d'utilisa- tion représentée à la figure 1. L'axe 13 pourra être réalisé par exemple sous la forme -d'une barre de torsion.A spring can easily be incorporated into the articulation axis 13 to automatically return the headrest to its position of use shown in FIG. 1. The axis 13 can be produced for example in the form -d 'a torsion bar.
Le fonctionnement de l'appui-tête, commandant l'escamotage tel que représenté à la figure 2, se déduit aisément de la description.The operation of the headrest, controlling the retraction as shown in Figure 2, is easily deduced from the description.
Sous l'effet du mouvement de rabattement du dossier 2 vers l'avant, la modification d'orientation des rampes 16 a pour effet de déplacer la masse d'inertie 15 dans le sens qui l'éloigne au crochet 17.Under the effect of the movement of the backrest 2 towards the front, the modification of the orientation of the ramps 16 has the effect of displacing the mass of inertia 15 in the direction which moves it away from the hook 17.
La mise en appui de l'appui-tête contre le fond de l'assise 1 au cours du basculement du dossier ou contre une surface d'appui telle que la face interne du pare-brise au cours du basculement du siège vers l'avant a pour effet de provoquer le basculement de l'appui-tête vers l'arrière du dossier. The support of the headrest against the bottom of the seat 1 during the tilting of the backrest or against a bearing surface such as the internal face of the windshield during the tilting of the seat forward has the effect of causing the headrest to tip backwards.
