Abstract
Description
1 L'invention concerne un dispositif de réception en coulissement de deuxThe invention relates to a sliding receiving device of two
tiges de montage d'un appui tête de siège de véhicule automobile, un siège et un appui-tête comprenant un tel dispositif. mounting rods of a motor vehicle seat head support, a seat and a headrest comprising such a device.
Il est connu de réaliser un dispositif de réception en coulissement de deux tiges sensiblement parallèles de montage d'un appui tête de siège de véhicule automobile, ledit dispositif comprenant une première et une deuxième gaine de logement respectif de chacune desdites tiges, lesdites gaines comprenant chacune une première zone extrême., située du côté de l'engagement desdites tiges, et une deuxième zone extrême, située à l'opposé, chacune desdites gaines étant insérée respectivement dans un premier et un deuxième support de sorte à être montées fixes par rapport auxdits supports. It is known to provide a device for sliding reception of two substantially parallel rods for mounting a motor vehicle seat head support, said device comprising a respective first and second housing sheath of each of said rods, said sheaths each comprising a first end zone, located on the engagement side of said rods, and a second extreme zone, situated opposite, each of said sleeves being respectively inserted in a first and a second support so as to be fixedly mounted relative to said supports.
Les tiges de montage de l'appui-tête sont généralement métalliques. On connaît notamment des tiges formant les branches d'un tube recourbé en U, lesdites tiges étant issues d'un coussin d'appui-tête. The mounting rods of the headrest are usually metal. In particular, rods forming the branches of a U-shaped curved tube are known, said rods being derived from a headrest cushion.
On connaît aussi des tiges sous forme de tubes sensiblement rectilignes, 20 lesdits tubes étant montés en partie supérieure d'une armature de dossier de siège et dirigées sensiblement vers le haut. Also known are rods in the form of substantially rectilinear tubes, said tubes being mounted in the upper part of a seat back frame and directed substantially upwards.
Dans tous les cas, l'entraxe entre les tiges peut présenter des dispersions dues aux tolérances de fabrication. In all cases, the spacing between the rods may have dispersions due to manufacturing tolerances.
Pour les mêmes raisons, les tiges peuvent présenter un parallélisme imparfait. For the same reasons, the stems may have imperfect parallelism.
En outre, le positionnement relatif des supports entre eux peut subir des dispersions. In addition, the relative positioning of the supports between them can undergo dispersions.
Pour toutes ces raisons, il peut s'avérer que le positionnement des tiges, notamment quant à leur entraxe, ne corresponde pas exactement à celui des 25 30 2 supports, ce qui peut entraîner des difficultés d'introduction des tiges dans les supports et des difficultés de coulissement. For all these reasons, it may prove that the positioning of the rods, especially as to their spacing, does not correspond exactly to that of the 25 2 supports, which can lead to difficulties in introducing the rods into the supports and sliding difficulties.
L'invention a pour but de pallier ces inconvénients. The invention aims to overcome these disadvantages.
A cet effet, et selon un premier aspect, l'invention propose un dispositif de réception en coulissement de deux tiges, sensiblement parallèles, de montage d'un appui tête de siège de véhicule automobile, ledit dispositif comprenant une première et une deuxième gaine de logement respectif de chacune desdites tiges, lesdites gaines comprenant chacune une première zone extrême, située du côté de l'engagement desdites tiges, et une deuxième zone extrême, située à l'opposé, chacune desdites gaines étant insérée respectivement dans un premier et un deuxième support de sorte que lesdites deuxièmes zones soient chacune en contact serrant avec ledit support correspondant, ladite première zone de ladite première gaine étant en contact serrant avec ledit premier support et ladite première zone de ladite deuxième gaine étant montée flottante par rapport audit deuxième support, de sorte à pouvoir débattre par rapport audit deuxième support. For this purpose, and according to a first aspect, the invention proposes a device for sliding reception of two rods, substantially parallel, for mounting a motor vehicle seat head support, said device comprising a first and a second sheath of respective housing of each of said rods, said sheaths each comprising a first end zone, located on the side of the engagement of said rods, and a second extreme zone, situated opposite, each of said sleeves being inserted respectively in a first and a second support so that said second zones are each in tight contact with said corresponding support, said first zone of said first cladding being in tight contact with said first support and said first zone of said second cladding being floating mounted relative to said second support, so as to be able to debate with respect to said second medium.
Dans cette description, les termes de positionnement dans l'espace (haut, bas,...) sont pris en référence au dispositif disposé dans le véhicule. In this description, the positioning terms in the space (up, down, ...) are taken in reference to the device disposed in the vehicle.
L'agencement proposé permet, du fait du débattement possible de la première zone extrême de la deuxième gaine par rapport au deuxième support, d'absorber les dispersions sus mentionnées, ce qui résout les difficultés d'introduction des tiges dans les supports et de coulissement. The proposed arrangement makes it possible, because of the possible displacement of the first end zone of the second sheath with respect to the second support, to absorb the abovementioned dispersions, which solves the difficulties of introducing the rods into the supports and sliding .
Selon un deuxième aspect, l'invention propose un siège comprenant un tel dispositif. Selon un troisième aspect, l'invention propose un appui-tête comprenant un tel dispositif.30 3 D'autres particularités et avantages de l'invention apparaîtront dans la description qui suit, faite en référence à la figure jointe qui est une représentation schématique en coupe d'un dispositif selon un mode de réalisation, ledit dispositif étant disposé en regard de deux tiges de montage d'appui-tête, représentées partiellement, avant leur introduction dans les gaines correspondantes. According to a second aspect, the invention proposes a seat comprising such a device. According to a third aspect, the invention proposes a headrest comprising such a device. Other features and advantages of the invention will appear in the description which follows, made with reference to the attached figure which is a diagrammatic representation in FIG. section of a device according to one embodiment, said device being disposed opposite two headrest mounting rods, partially shown, before their introduction into the corresponding sleeves.
En référence à la figure, on décrit un dispositif 1 de réception en coulissement de deux tiges 2, sensiblement parallèles, lesdites tiges pouvant présenter une légère courbure, de montage d'un appui tête de siège de véhicule automobile, ledit dispositif comprenant une première 3 et une deuxième 4 gaine de logement respectif de chacune desdites tiges, lesdites gaines comprenant chacune une première zone 5a,5b extrême, située du côté de l'engagement desdites tiges, et une deuxième zone 6a,6b extrême, située à l'opposé, chacune desdites gaines étant insérée respectivement dans un premier 7 et un deuxième 8 support de sorte que lesdites deuxièmes zones soient chacune en contact serrant avec ledit support correspondant, ladite première zone de ladite première gaine étant en contact serrant avec ledit premier support, notamment de sorte à permettre un montage fixe de ladite première gaine sur ledit premier support, et ladite première zone de ladite deuxième gaine étant montée flottante par rapport audit deuxième support, de sorte à pouvoir débattre par rapport audit deuxième support. Referring to the figure, there is described a device 1 for sliding reception of two rods 2, substantially parallel, said rods may have a slight curvature, mounting a motor vehicle headrest, said device comprising a first 3 and a second respective housing sheath of each of said rods, said sheaths each comprising a first zone 5a, 5b extreme, located on the side of the engagement of said rods, and a second zone 6a, 6b extreme, located opposite, each of said sleeves being respectively inserted in a first 7 and a second 8 support so that said second zones are each in tight contact with said corresponding support, said first zone of said first sleeve being in close contact with said first support, in particular so to allow a fixed mounting of said first sheath on said first support, and said first zone of said second e sheath being mounted floating relative to said second support, so as to be able to debate with respect to said second support.
Le débattement peut notamment se faire dans le plan défini par les axes de coulissement 12 des gaines 3,4, ce qui permet une oscillation (symbolisées par des flèches) de la deuxième gaine 4 selon un axe de rotation 9 disposé à proximité de la deuxième zone 6b et perpendiculaire audit plan. The deflection can in particular be done in the plane defined by the sliding axes 12 of the sheaths 3,4, which allows an oscillation (symbolized by arrows) of the second sheath 4 along an axis of rotation 9 disposed near the second zone 6b and perpendicular to said plane.
