Abstract

The metal rod comprises a metal coating layer deposited by electrolysis of zinc solution. The layer comprises varnish, and pure zinc. The metal coating comprises zinc alloy. Independent claims are included for: (1) a device for mounting and slide blocking a metal rod; (2) a framework of headrest; and (3) a headrest for a seat of a motor vehicle.

Description

1 L'invention concerne une tige métallique de montage d'un appui-tête sur un dossier de siège de véhicule automobile, un dispositif de montage et de blocage en coulissement d'une telle tige, une armature d'appui-tête comprenant au moins une telle tige, un appui-tête de siège de véhicule automobile comprenant une telle armature et un siège de véhicule automobile comprenant au moins une telle tige. The invention relates to a metal rod for mounting a headrest on a motor vehicle seat back, a device for mounting and locking in sliding of such a rod, a headrest frame comprising at least one such a rod, a motor vehicle seat headrest comprising such a frame and a motor vehicle seat comprising at least one such rod.

Il est connu de réaliser une tige métallique de montage d'un appui-tête sur un dossier de siège de véhicule automobile, ladite tige étant revêtue, au moins en partie, d'une couche de nickel d'apprêt et d'une couche de revêtement en chrome, ceci notamment à des fins esthétiques. It is known to produce a metal rod for mounting a headrest on a motor vehicle seat back, said rod being coated, at least in part, with a layer of nickel and a primer layer. chromium coating, this in particular for aesthetic purposes.

Cependant, un tel agencement présente divers inconvénients. Le dépôt d'une couche de nickel d'apprêt complexifie la réalisation et engendre des surcoûts importants, ceci d'autant plus que le nickel est un métal onéreux. De plus, le chrome est un métal que l'on cherche à éradiquer des véhicules automobile pour des raisons environnementales. However, such an arrangement has various disadvantages. The deposition of a layer of nickel refinement complicates the implementation and generates significant additional costs, especially since nickel is an expensive metal. In addition, chromium is a metal that is sought to eradicate motor vehicles for environmental reasons.

L'invention a pour but de proposer un agencement moins coûteux, respectueux 20 de l'environnement et d'esthétique analogue à celle obtenue avec des revêtements en chrome. The object of the invention is to provide a less expensive, environmentally friendly and aesthetic arrangement similar to that obtained with chrome coatings.

A cet effet, et selon un premier aspect, l'invention propose une tige métallique de montage d'un appui-tête sur un dossier de siège de véhicule automobile, 25 ladite tige étant revêtue, au moins en partie, d'une couche de revêtement métallique déposée par électrolyse d'une solution de zinc, ladite couche étant recouverte d'un vernis. For this purpose, and according to a first aspect, the invention proposes a metal rod for mounting a headrest on a motor vehicle seat back, said rod being coated, at least in part, with a layer of metal coating deposited by electrolysis of a zinc solution, said layer being coated with a varnish.

La demanderesse a constaté qu'un tel revêtement pourvu d'un vernis est 30 d'aspect analogue à ceux en chrome. En outre, l'agencement proposé entraîne une simplification du procédé de fabrication et une baisse des coûts. Enfin, la suppression du chrome apporte un avantage environnemental. 2 Selon d'autres aspects, l'invention propose un dispositif de montage et de blocage en coulissement d'une telle tige, une armature d'appui-tête comprenant au moins une telle tige, un appui-tête de siège de véhicule automobile comprenant une telle armature et un siège de véhicule automobile comprenant au moins une telle tige. The Applicant has found that such a coating provided with a varnish is similar in appearance to those in chrome. In addition, the proposed arrangement leads to simplification of the manufacturing process and lower costs. Finally, the removal of chromium provides an environmental benefit. According to other aspects, the invention proposes a sliding mounting and locking device for such a rod, a headrest armature comprising at least one such rod, a motor vehicle seat headrest comprising such a frame and a motor vehicle seat comprising at least one such rod.

D'autres particularités et avantages de l'invention apparaîtront dans la description qui suit. Other features and advantages of the invention will become apparent in the description which follows.

On décrit une tige métallique de montage d'un appui-tête sur un dossier de siège de véhicule automobile, ladite tige étant revêtue, au moins en partie, d'une couche de revêtement métallique déposée par électrolyse d'une solution de zinc, ladite couche étant recouverte d'un vernis. A metal rod for mounting a headrest on a motor vehicle seat back, said rod being coated, at least in part, with a metal coating layer deposited by electrolysis of a zinc solution, said layer being covered with a varnish.

La couche de revêtement métallique peut être constituée de zinc pur ou d'un alliage de zinc, dans lequel le zinc est majoritaire. The metal coating layer may be pure zinc or a zinc alloy in which zinc is predominant.

Par solution de zinc, on entend une solution comprenant des ions de zinc, et éventuellement au moins un autre métal dans le cas où l'on réalise un dépôt d'alliage de zinc By zinc solution is meant a solution comprising zinc ions, and possibly at least one other metal in the case where a zinc alloy deposit is made.

On décrit à présent un dispositif de montage et de blocage en coulissement d'une telle tige, ledit dispositif comprenant au moins un cran de blocage disposé sur ladite tige et un tiroir réciproque mobile en translation dans une gaine de réception de ladite tige en coulissement, la surface de contact dudit tiroir avec ladite tige étant en matière plastique, ceci afin d'éviter un éraillement de ladite tige avec le temps. There is now described a device for mounting and locking in sliding of such a rod, said device comprising at least one locking notch disposed on said rod and a reciprocal slide movable in translation in a receiving sheath of said sliding rod, the contact surface of said slide with said rod being plastic, in order to avoid a scuffing of said rod with time.

On décrit à présent une armature d'appui-tête comprenant au moins une telle tige, ladite armature comprenant un tube métallique, notamment conformé en U, ladite tige étant formée par une partie extrême dudit tube. 3 On décrit à présent un appui-tête de siège de véhicule automobile comprenant un coussin et une telle armature, la tige étant saillante dudit coussin. We now describe a headrest frame comprising at least one such rod, said armature comprising a metal tube, in particular U-shaped, said rod being formed by an end portion of said tube. 3 We now describe a motor vehicle seat headrest comprising a cushion and such an armature, the rod being projecting from said cushion.

On décrit en variante un siège de véhicule automobile, ledit siège comprenant 5 au moins une telle tige, ladite tige étant solidaire de l'armature du dossier et saillante du haut dudit dossier. An alternative embodiment of a motor vehicle seat, said seat comprising at least one such rod, said rod being integral with the backrest frame and protruding from the top of said backrest.
