Abstract

The element has an armature (1) including a folded metallic rod (2) with ends (3) associated with each other by an association piece (4) such that the rod is closed on itself. The association piece is made of molded plastic material and provided with interlocking units (5) to interlock the ends. The piece has hooking units (6) to hook a zone (7) of the rod by interlocking, where the zone is arranged remote from the ends.

Description

1 L'invention concerne un élément périphérique de siège de véhiculeThe invention relates to a peripheral element of a vehicle seat

automobile. Il est connu de réaliser un élément périphérique de siège de véhicule automobile, tel qu'un accoudoir ou un dormant, ledit élément comprenant une 5 armature, ladite armature comprenant une tige métallique conformée, éventuellement creuse, dont les extrémités sont associées entre elles par soudure de sorte que ladite tige soit refermée sur elle même. L'opération de soudure complexifie la réalisation de l'armature. En outre, elle 10 occasionne une déformation de la tige et génère, en cas de soudage à l'arc, des pétillons de soudure, lesdits pétillons risquant de détériorer la mousse utilisée généralement pour recouvrir l'armature et apporter un confort à l'utilisateur. 15 On connaît aussi un élément de siège dont l'armature est formée d'une pièce en matière plastique moulée. Une telle pièce, pour présenter la résistance requise, doit présenter des dimensions importantes et donc subit des dispersions dimensionnelles importantes. En outre, le moule de réalisation d'une telle pièce est complexe et coûteux. Par ailleurs, elle doit être accrochée 20 sur son environnement en plusieurs points pour que son accrochage soit suffisamment résistant, ce qui complexifie son montage. L'invention a pour but de pallier ces inconvénients. 25 A cet effet, l'invention propose un élément périphérique de siège de véhicule automobile, ledit élément comprenant une armature, ladite armature comprenant une tige métallique conformée dont les extrémités sont associées entre elles de sorte que ladite tige soit refermée sur elle même, lesdites extrémités étant associées entre elles au moyen d'une pièce d'association en 30 matière plastique moulée pourvue de moyens d'emboîtement desdites extrémités. 2903637 2 De la sorte, on obtient un élément dont l'armature est robuste, et ceci sans opération de soudage, la pièce d'association permettant d'assurer l'association entre les extrémités de la tige métallique.  automobile. It is known to provide a peripheral element of a motor vehicle seat, such as an armrest or a frame, said element comprising a frame, said armature comprising a shaped metal rod, possibly hollow, the ends of which are associated with each other by welding so that said rod is closed on itself. The welding operation complicates the realization of the armature. In addition, it causes a deformation of the rod and generates, in the case of arc welding, welding burrs, said bursts may damage the foam generally used to coat the frame and provide comfort to the user. . Also known is a seat member whose frame is formed of a molded plastic part. Such a piece, to present the required resistance, must have significant dimensions and therefore undergo significant dimensional dispersions. In addition, the mold for producing such a part is complex and expensive. Moreover, it must be hooked on its environment at several points so that its attachment is sufficiently resistant, which complicates its assembly. The invention aims to overcome these disadvantages. To this end, the invention proposes a peripheral element of a motor vehicle seat, said element comprising a frame, said armature comprising a shaped metal rod whose ends are associated with each other so that said rod is closed on itself, said ends being associated with each other by means of a molded plastics association piece provided with means for interlocking said ends. In this way, one obtains an element whose reinforcement is robust, and this without welding operation, the association piece to ensure the association between the ends of the metal rod.

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 d'une armature selon une réalisation. En référence à la figure, on décrit à présent un élément périphérique de siège 10 de véhicule automobile, tel qu'un accoudoir ou un dormant, ledit élément comprenant une armature 1, ladite armature comprenant une tige 2 métallique conformée, notamment par pliage, ladite tige étant éventuellement creuse, dont les extrémités 3 sont associées entre elles de sorte que ladite tige soit refermée sur elle même, lesdites extrémités étant associées entre elles au moyen d'une 15 pièce 4 d'association en matière plastique moulée pourvue de moyens d'emboîtement 5 desdites extrémités. Selon la réalisation représentée, la pièce 4 d'association s'étend à distance des extrémités 3, ladite pièce comprenant au moins un moyen d'accrochage 6 par 20 emboîtement d'une zone 7 de ladite tige disposée à distance desdites extrémités. Une telle réalisation permet notamment de bien indexer le positionnement de la tige 2 dans l'espace.  Other features and advantages of the invention will appear in the description which follows, made with reference to the attached figure which is a schematic representation of a frame according to one embodiment. Referring to the figure, there is now described a peripheral element 10 of a motor vehicle, such as an armrest or a frame, said element comprising a frame 1, said armature comprising a metal rod 2 shaped, in particular by folding, said rod being optionally hollow, the ends 3 are associated with each other so that said rod is closed on itself, said ends being associated with each other by means of a part 4 of association molded plastic provided with means of interlocking 5 of said ends. According to the embodiment shown, the part 4 of association extends at a distance from the ends 3, said part comprising at least one attachment means 6 by interlocking an area 7 of said rod disposed at a distance from said ends. Such an embodiment makes it possible in particular to index well the positioning of the rod 2 in the space.

25 De façon non représentée, la pièce 4 d'association peut comprendre au moins un organe fonctionnel issu de moulage, notamment un guide de sangle en haut de dormant ou un moyen de montage à son environnement, par exemple le dossier du siège ou la structure du véhicule. Du fait de la faible taille de la pièce 30 4, ledit moyen de montage présente des dispersions faibles, ce qui garantit le bon positionnement de l'élément dans le véhicule.In a manner not shown, the association piece 4 may comprise at least one functional member resulting from molding, in particular a webbing guide at the top of the frame or a mounting means to its environment, for example the seat backrest or the structure of the vehicle. Due to the small size of the part 4, said mounting means has low dispersions, which ensures the proper positioning of the element in the vehicle.

2903637 3 Selon une réalisation non représentée, l'armature 1 est recouverte d'un bloc de matériau souple, notamment en mousse, ledit bloc étant revêtu d'une coiffe de revêtement, tel qu'un textile, de sorte à obtenir un élément selon l'invention.According to an embodiment not shown, the armature 1 is covered with a block of flexible material, in particular foam, said block being coated with a coating cap, such as a textile, so as to obtain an element according to the invention.
