Description

Appui-tête de véhicule automobile comprenant un axe de rotationAutomotive headrest comprising an axis of rotation

d'une palette s L'invention concerne un appui-tête de véhicule automobile.  The invention relates to a headrest of a motor vehicle.

Plus particulièrement, l'invention concerne un appui-tête comprenant deux parties articulées en rotation entre elles, de sorte à permettre son réglage en confort. i0  More particularly, the invention relates to a headrest comprising two parts articulated in rotation between them, so as to allow its adjustment in comfort. i0

Il est connu de réaliser des appuis-tête articulés en rotation comprenant une armature de montage à un dossier et un coussin d'appui-tête pourvu d'une structure rigide, ladite structure étant associée en rotation à ladite armature au moyen d'un système is d'articulation autour d'un axe de sorte à permettre un réglage du coussin.  It is known to produce rotationally articulated headrests comprising a backrest mounting frame and a headrest cushion provided with a rigid structure, said structure being associated in rotation with said armature by means of a system is hinge about an axis so as to allow adjustment of the cushion.

Il est connu, notamment du document EP-0 764 557, d'utiliser des systèmes d'articulation de type pince métallique, ladite pince étant associée à ladite structure et enserrant une partie centrale cylindrique métallique de ladite armature, de sorte à permettre une rotation de ladite structure autour de ladite partie cylindrique.  It is known, in particular from document EP-0 764 557, to use clamping systems of the metal clamp type, said clamp being associated with said structure and enclosing a cylindrical central metal part of said frame, so as to allow rotation said structure around said cylindrical portion.

Dans un appui-tête dit à palette , tel que décrit par exemple dans 25 le document FR-2 747 349, la structure de coussin est formée d'une palette montée en rotation par rapport à l'armature.  In a so-called pallet headrest, as described for example in document FR-2 747 349, the cushion structure is formed of a pallet mounted to rotate relative to the armature.

Selon une réalisation, l'armature est solidaire d'un boîtier, permettant notamment le réglage en hauteur de l'appui-tête. La palette est alors montée en rotation par rapport au boîtier autour d'un axe solidaire de ce boîtier.  According to one embodiment, the frame is integral with a housing, allowing in particular the height adjustment of the headrest. The pallet is then rotated relative to the housing around an axis integral with this housing.

L'axe doit être fixé au boîtier de façon ferme et inamovible, tout en présentant un encombrement et un poids minimaux.  The shaft must be securely and securely attached to the housing, with minimal bulk and weight.

L'invention vise à remplir cet objectif en proposant un appui-tête de véhicule automobile dans lequel l'axe est associé au boîtier de façon particulièrement simple, robuste et avec un encombrement et 5 un poids minimaux.  The invention aims to fulfill this objective by providing a motor vehicle headrest in which the axis is associated with the housing particularly simple, robust and with a footprint and a minimum weight.

A cet effet, l'invention concerne un Appui-tête pour véhicule automobile comprenant: É une armature de montage sur un dossier de siège, lo ^ un boîtier associé à la partie supérieure de ladite armature, É un axe de rotation cylindrique associé à la partie supérieure dudit boîtier, É une palette formant structure de coussin d'appui-tête, mobile en rotation selon ledit axe par rapport audit boîtier, les parties extrêmes de l'axe étant disposées respectivement dans un premier et un deuxième logement prévus transversalement de part et d'autre du boîtier, au moins une partie extrême dudit axe étant aplatie, ladite partie extrême aplatie étant logée dans le premier logement, ledit premier logement présentant une forme complémentaire à celle de ladite partie extrême aplatie, ledit premier logement présentant une ouverture supérieure, ladite ouverture étant obstruée par un cavalier associé audit premier logement par emboîtement.  To this end, the invention relates to a headrest for a motor vehicle comprising: E a mounting frame on a seat back, lo ^ a housing associated with the upper part of said frame, É a cylindrical axis of rotation associated with the upper part of said housing, É a pallet forming a headrest cushion structure, rotatable along said axis relative to said housing, the end portions of the axis being respectively disposed in a first and a second housing provided transversely from and other housing, at least an end portion of said axis being flattened, said flattened end portion being housed in the first housing, said first housing having a shape complementary to that of said flattened end portion, said first housing having a top opening said opening being obstructed by a jumper associated with said first housing by interlocking.

Ainsi, l'axe de rotation est formé d'une simple tige emboutie, particulièrement simple à réaliser et de faible poids. La tige présente un encombrement très faible et peut être simplement associée au boîtier. De plus, l'association de l'axe au boîtier est suffisamment ferme, notamment du fait de la présence du cavalier pour présenter les garanties de sécurité en cas de choc.  Thus, the axis of rotation is formed of a simple stamped rod, particularly simple to produce and low weight. The rod has a very small footprint and can be simply associated with the housing. In addition, the association of the axis to the housing is sufficiently firm, especially because of the presence of the rider to present the security guarantees in case of shock.
