Abstract

The seat headrest consists of a main cushion (12) fitted to a frame (11), and which incorporates an integral neck support in the form of a pneumatic cushion (16) connected to a regulating pump and fixed by a surround (15) to the frame. The main cushion has a recess at one side to contain the regulating pump and an inner cavity to receive the pneumatic chamber and its surround, with access through a slit in the bottom of the main cushion.

Description

DISPOSITIF REPOSE-TETE AVEC APPUI CERVICAL INTEGRE
L'invention concerne un dispositif repose-tête avec appui cervical intégré du type comportant un coussin pneumatique relié à une pompe de réglage dudit appui.HEADREST DEVICE WITH INTEGRATED CERVICAL SUPPORT
The invention relates to a headrest device with integrated cervical support of the type comprising a pneumatic cushion connected to a pump for adjusting said support.

La publication EP-A-0317762 décrit un repose-tete intégré au dossier d'un siège dans lequel rappui cervical est constitué par une enveloppe dont le volume ajustable est relié à une pompe à vide destinée à modeler le contour de renveloppe à la morphologie de roccupant du siège.Publication EP-A-0317762 describes a headrest integrated into the back of a seat in which the cervical joint is constituted by an envelope whose adjustable volume is connected to a vacuum pump intended to shape the contour of the envelope with the morphology of occupying the seat.

Les moyens d'ajustement et de réglage de rappui cervical sont localisés dans ce cas sur le dossier du siège. n en résulte que le dispositif ne peut-être ni séparé du siège ni être monté sur un siège existant.The means of adjustment and adjustment of cervical compression are located in this case on the seat back. As a result, the device can neither be separated from the seat nor be mounted on an existing seat.

L'invention a pour objet un dispositif repose-tête avec appui cervical intégré, caractérisé par le fait que le coussin pneumatique est solidaire d'un support de fixation porté par rarmature du coussin d'appui constitutif du repose-tête dont un flanc porte le logement de montage de la pompe de réglage de appui cervical.The subject of the invention is a headrest device with integrated cervical support, characterized in that the air cushion is integral with a fixing support carried by reinforcement of the support cushion constituting the headrest, one side of which carries the cervical support adjustment pump mounting housing.

Le dispositif repose-tête ainsi réalisé possède ravantage de pouvoir être monté et démonté à volonté sur l'un quelconque des sièges du véhicule. Par voie de conséquence il constitue un élément de confort qui permet d'éviter la lordose cervicale.The headrest device thus produced has the advantage of being able to be mounted and dismounted at will on any of the vehicle seats. Consequently, it constitutes an element of comfort which makes it possible to avoid cervical lordosis.

D'autres caractéristiques et avantages du dispositif apparattront à la lecture d'un mode de réalisation du repose-tête en référence au dessin annexé dans lequel: - la figure 1 est une représentation perspective du dispositif repose-tête
avec coupe transversale, - la figure 2 est une vue en coupe transversale médiane du dispositif
représenté à la figure 1, suivant la ligne H-H de la figure 3, - la figure 3 est une vue en coupe longitudinale du dispositif suivant la ligne
m-m de la figure 2.Other characteristics and advantages of the device will appear on reading an embodiment of the headrest with reference to the appended drawing in which: - Figure 1 is a perspective representation of the headrest device
with cross section, - Figure 2 is a median cross section of the device
shown in Figure 1, along the line HH of Figure 3, - Figure 3 is a longitudinal sectional view of the device along the line
mm in Figure 2.

En référence au dessin, le repose-tête 10 est constitué par une armature tubulaire 1 1 en U, dont les terminaisons constituent les pieds de fixation sur un élément d'armature porté par le dossier non représenté d'un siège de véhicule.Referring to the drawing, the headrest 10 is constituted by a tubular frame 1 1 in a U, the terminations of which constitute the fixing feet on a frame element carried by the not shown back of a vehicle seat.

L'armature 1 1 supporte un coussin d'appui 12 en matériau cellulaire recouvert d'un tissu d'habillage constitutif d'une enveloppe 13.The frame 11 supports a support cushion 12 of cellular material covered with a covering fabric constituting an envelope 13.

Le coussin d'appui 12 possède une chambre intérieure qui constitue la chambre de montage 14 d'un support 15 de fixation du coussin pneumatique 16. Le support 15 est solidaire des branches latérales de l'armature 11 par cordons de soudure 15a.The support cushion 12 has an interior chamber which constitutes the assembly chamber 14 of a support 15 for fixing the pneumatic cushion 16. The support 15 is secured to the lateral branches of the frame 11 by weld beads 15a.

Le coussin 16 est constitué par une enveloppe souple étanche qui possède des oeillets d'agrafage 17 sur le support 15. Le coussin 16 est monté dans la chambre de montage 14 par une fente d'introduction 18 et est branché sur un conduit de pression 19 d'une pompe de réglage 20 débouchant dans ladite chambre. La pompe 20 est constituée par une poire localisée dans le logement de montage 21 ouvert sur le flanc latéral 22 du coussin d'appui 12.The cushion 16 consists of a flexible waterproof envelope which has stapling eyelets 17 on the support 15. The cushion 16 is mounted in the mounting chamber 14 by an insertion slot 18 and is connected to a pressure conduit 19 an adjustment pump 20 opening into said chamber. The pump 20 consists of a bulb located in the mounting housing 21 open on the lateral flank 22 of the support cushion 12.

La pompe 20 est masquée par l'enveloppe 13 qui confère de la sorte au repose tête un bon aspect de finition.The pump 20 is masked by the casing 13 which thus gives the headrest a good finish appearance.

La pompe 20 porte par affineurs une valve anti-retour 23 avec conduit d'échappement qui permet: - le gonflage correct du coussin 16 dans le but de réaliser l'appui cervical
recherché. The pump 20 carries by refiners a non-return valve 23 with exhaust duct which allows: - the correct inflation of the cushion 16 in order to achieve the cervical support
research.

- le dégonflage du coussin 16 dans le but de supprimer l'appui cervicaL
Le dispositif repose-tête ainsi réalisé peut-être élaboré à raide de matériaux conventionnels et porter tout dispositif additionnel de réglage en hauteur ou en inclinaison, sans sortir pour autant du cadre de rinvention.- deflation of the cushion 16 in order to remove the cervical support
The headrest device thus produced can be developed using conventional materials and carry any additional height or tilt adjustment device, without however departing from the scope of the invention.

Le dispositif repose-tête avec appui cervical intégré peut être en outre complété par un appui latéral additionnel également gonflable dans le but de combler respace existant résiduel entre le repose-tête et la paroi latérale du véhicule.The headrest device with integrated cervical support can also be supplemented by an additional lateral support, also inflatable, with the aim of filling the residual existing space between the headrest and the side wall of the vehicle.

Bien entendu d'autres perfectionnements et modifications du reposetête peuvent être imaginés sans sortir pour autant du cadre de l'invention. Of course other improvements and modifications of the headrest can be imagined without departing from the scope of the invention.
