Description

Appui-tête de siège de véhicule automobile Automotive headrest headrest
L'invention concerne un appui-tête de siège de véhicule automobile.The invention relates to a headrest of a motor vehicle seat.
II est connu de réaliser un appui-tête comprenant une armature, notamment tubulaire, de montage sur le dossier du siège, ladite armature présentant une forme générale de U renversé dont la partie supérieure est repliée vers l'avant de sorte à être inscrite dans un plan sensiblement parallèle au plan défini par la partie inférieure des branches du U.It is known to make a headrest comprising an armature, in particular tubular, for mounting on the back of the seat, said armature having a generally U-shaped overturned, the upper part of which is folded forward so as to be inscribed in a plane substantially parallel to the plane defined by the lower part of the branches of the U.
Un tel appui-tête est notamment utilisé sur les sièges arrière, sa forme permettant de le régler en position basse, lorsqu'il n'est pas utilisé, dégageant la visibilité vers l'arrière.Such a headrest is used in particular on the rear seats, its shape to adjust it in the low position, when not in use, giving visibility to the rear.
Les réalisation connues prévoient notamment que la partie supérieure de l'armature soit surmoulée par - ou insérée dans - un bloc de mousse, ledit bloc étant revêtu par une coiffe en matériau de revêtement, notamment à base de textile, ladite coiffe comprenant au moins deux flans associés entre eux, notamment par couture.The known embodiments provide in particular for the upper part of the reinforcement to be overmolded by - or inserted in - a block of foam, said block being coated with a cap made of a coating material, in particular a textile base, said cap comprising at least two blanks associated with each other, in particular by sewing.
Une telle réalisation est complexe et coûteuse, notamment en raison de la grande quantité de matériau de revêtement employé pour réaliser la coiffe et de l'opération d'association des flans, notamment par couture.Such an embodiment is complex and expensive, in particular because of the large amount of coating material used to make the cap and the operation of association of the blanks, in particular by sewing.
L'invention a pour but de pallier ces inconvénients.The invention aims to overcome these disadvantages.
A cet effet, l'invention propose un appui-tête de siège de véhicule automobile, comprenant une armature de montage sur le dossier dudit siège, ladite armature présentant une forme générale de U renversé dont la partie supérieure est repliée vers l'avant de sorte à être inscrite dans un plan sensiblement parallèle au plan défini par la partie inférieure des branches du U, ledit appui-tête comprenant en outre : • une coque avant rigide recouvrant la partie repliée du U, ladite coque comprenant une face avant et une face arrière pourvue de moyens d'association à ladite armature,For this purpose, the invention provides a motor vehicle seat headrest, comprising a mounting frame on the backrest of said seat, said armature having a generally U-shaped overturned, the upper part is bent forwardly so to be inscribed in a plane substantially parallel to the plane defined by the lower part of the branches of the U, said headrest further comprising: A rigid front shell covering the folded portion of the U, said shell comprising a front face and a rear face provided with means of association with said armature,
• un flan de matériau de revêtement associé par des moyens de fixation à ladite coque avant en regard de ladite face avant,A blank of coating material associated with fastening means to said front shell facing said front face,
• un bloc de matériau élastique disposé entre ledit flan et ladite face avant.A block of elastic material disposed between said blank and said front face.
Dans cette description, les termes de positionnement dans l'espace (avant, arrière, inférieur, supérieur,...) sont pris en référence à l'appui-tête disposé dans le véhicule.In this description, the positioning terms in the space (front, rear, bottom, top, ...) are taken with reference to the headrest disposed in the vehicle.
La description qui suit est faite en référence à la figure jointe qui est une représentation en perspective éclatée d'un appui-tête selon une réalisation.The following description is made with reference to the attached figure which is an exploded perspective representation of a headrest according to one embodiment.
En référence à la figure, on décrit un appui-tête 1 de siège de véhicule automobile, comprenant une armature 2 de montage, notamment tubulaire, sur le dossier dudit siège, ladite armature présentant une forme générale de U renversé dont la partie supérieure 3 est repliée vers l'avant de sorte à être inscrite dans un plan sensiblement parallèle au plan défini par la partie inférieure des branches 4 du U, ledit appui-tête comprenant en outre :Referring to the figure, there is described a headrest 1 of a motor vehicle seat, comprising a mounting frame 2, in particular tubular, on the backrest of said seat, said armature having a generally U-shaped overturned whose upper part 3 is folded forward so as to be inscribed in a plane substantially parallel to the plane defined by the lower part of the branches 4 of the U, said headrest further comprising:
• une coque avant 5 rigide, notamment en plastique moulé, recouvrant la partie 3 repliée du U, ladite coque comprenant une face avant 6 et une face arrière 7 pourvue de moyens d'association 8 à ladite armature, ici sous forme de clips, • un flan 9 de matériau de revêtement, notamment de textile ou de cuir, associé par des moyens de fixation, non représentés, à ladite coque avant en regard de ladite face avant,A rigid front shell 5, in particular made of molded plastic, covering the folded portion 3 of the U, said shell comprising a front face 6 and a rear face 7 provided with association means 8 to said frame, here in the form of clips, a blank 9 of coating material, in particular of textile or leather, associated by fixing means, not shown, to said front shell opposite said front face,
• un bloc 10 de matériau élastique disposé entre ledit flan et ladite face avant. De façon non représentée, la face arrière 7 peut comprendre en sa périphérie une pluralité de picots de fixation, lesdits picots étant plantés en périphérie du flan 9 pour former moyens de fixation.A block of elastic material disposed between said blank and said front face. In a manner not shown, the rear face 7 may comprise at its periphery a plurality of fixing pins, said pins being planted at the periphery of the blank 9 to form fixing means.
De façon non représentée, le flan 9 peut être associé à la coque avant 5 par des agrafes plantées en périphérie de la face arrière 7 formant moyens de fixation.In a manner not shown, the blank 9 may be associated with the front shell 5 by staples planted at the periphery of the rear face 7 forming fixing means.
L'appui-tête comprend en outre une coque arrière 11 solidaire, par exemple par emboîtement, de la coque avant 5 et s'étendant en regard des moyens de fixation de sorte à les masquer.The headrest further comprises a rear shell 11 integral, for example by interlocking, the front shell 5 and extending opposite the fastening means so as to hide them.
Le flan 9 présente ici une forme sensiblement rectangulaire, ce qui permet de minimiser les chutes de découpe du matériau de revêtement.The blank 9 here has a substantially rectangular shape, which makes it possible to minimize the cutting falls of the coating material.
Selon une réalisation, le bloc 10 est à base de flocons de mousse souple agglomérée, notamment issus du recyclage. En variante, il est à base de feutre. According to one embodiment, the block 10 is based on agglomerated soft foam flakes, in particular derived from recycling. Alternatively, it is based on felt.
