Description
APPUI-TETE <B>DE</B> FORME MODIFIABLE La présente invention concerne un appui-tête de forme modifiable pour siège, notamment de véhicule automobile, et plus particulièrement un tel appui-tête comportant un coussin monté sur une armature de montage. The present invention relates to a headrest of modifiable shape for a seat, particularly a motor vehicle, and more particularly to such a headrest comprising a cushion mounted on a mounting frame.
On connaît<B>déjà</B> de tels appuis-tête dans lesquels, par exemple, la forme du coussin peut être modifiée pour en régler l'inclinaison, tant pour des raisons de confort que pour des raisons de sécurité. Already known <B> already </ B> such headrests in which, for example, the shape of the cushion can be changed to adjust the inclination, both for reasons of comfort for security reasons.
<B>Il</B> peut toutefois être également utile d'en modifier la concavité (vers l'avant du véhicule), essentiellement pour des raisons de confort. C'est ainsi que l'on peut souhaiter disposer d'un appui-tête relativerni ent plat dans des conditions normales ou, au contraire, d'avoir plus de soutien pour la tête, pour des conditions de conduite plus sévères ou pour les passagers dans des situations de repos. <B> It </ B> can however also be useful to modify the concavity (towards the front of the vehicle), mainly for reasons of comfort. Thus, one may wish to have a relatively flat head restraint under normal conditions or, on the contrary, to have more support for the head, for harsher driving conditions or for passengers in rest situations.
La présente invention vise<B>à</B> fournir un tel appui-tête dont la concavité est réglable. The present invention aims to provide such a headrest whose concavity is adjustable.
Plus particulièrement, l'invention a pour but de fournir un appui- tête de concavité réglable, dans lequel la garniture extérieure et l'enveloppe extérieure suivent les déformations de l'appui-tête. More particularly, the invention aims to provide an adjustable concavity headrest, wherein the outer lining and the outer shell follow the deformations of the headrest.
<B>A</B> cet effet, l'invention a pour objet un appui-tête de forme modifiable pour siège, notamment de véhicule automobile, comportant un coussin monté sur une armature de montage, caractérisé par le fait que ledit coussin comprend deux parties sensiblement symétriques par rapport<B>à</B> un plan de symétrie central sensiblement vertical, chacune desdites parties étant agencée pour pivoter autour d'un axe de rotation sensiblement vertical pour donner <B>à</B> l'appui-tête une concavité variable. <B> A </ B> With this effect, the object of the invention is a headrest of modifiable shape for a seat, particularly a motor vehicle, comprising a cushion mounted on a mounting frame, characterized in that said cushion comprises two parts substantially symmetrical with respect to a substantially vertical central plane of symmetry, each of said portions being arranged to pivot about a substantially vertical axis of rotation to give <B> to </ B> headrest a variable concavity.
Dans un mode de réalisation particulier, chacune desdites parties est agencée pour pivoter autour d'un axe de rotation distinct, lesdits axes de rotation étant disposés symétriquement de part et d'autre dudit plan de symétrie. In a particular embodiment, each of said parts is arranged to pivot about a separate axis of rotation, said axes of rotation being arranged symmetrically on either side of said plane of symmetry.
En variante, les deux parties pourraient pivoter autour du même axe de rotation qui serait alors situé dans le plan de symétrie. Toutefois, l'utilisation de deux axes distincts facilite les déformations de la garniture intérieure et de l'enveloppe extérieure de l'appui-tête et procure, dans le cas d'une forte concavité, un meilleur confort<B>à</B> l'utilisateur. Alternatively, the two parts could rotate about the same axis of rotation which would then be located in the plane of symmetry. However, the use of two separate axes facilitates the deformation of the lining and the outer shell of the headrest and provides, in the case of a strong concavity, a better comfort <B> to </ B > the user.
Plus particulièrement, ladite ouverture de montage peut comporter deux broches sensiblement verticales, auquel cas lesdits axes de rotation peuvent être formés par lesdites broches. More particularly, said mounting aperture may comprise two substantially vertical pins, in which case said axes of rotation may be formed by said pins.
On connaît<B>déjà</B> de telles armatures dont les broches sont engagées dans des douilles solidaires du dossier du siège pour le réglage en hauteur de l'appui-tête. Already known <B> already </ B> such reinforcements whose pins are engaged in sleeves secured to the seat back for adjusting the height of the headrest.
Chaque partie de l'appui-tête peut comporter une pièce d'armature, lesdites pièces d'armature comportant chacune une denture d'engrenage, lesdites dentures étant agencées pour engrener avec une pièce dentée intermédiaire. Each part of the headrest may comprise an armature piece, said armature parts each having a gear teeth, said teeth being arranged to mesh with an intermediate toothed part.
Du fait de cet engrenage, les mouvements des deux parties de l'appui-tête sont coordonnés.<B>Il</B> suffit, en particulier, d'agir sur une seule des parties pour assurer un déplacement symétrique des deux parties. La pièce dentée intermédiaire permet d'assurer des mouvements des deux parties en sens inverse, c'est-à-dire que soit les deux parties se rapprochent du plan de symétrie, soit elles s'en écartent. Because of this gear, the movements of the two parts of the headrest are coordinated. <B> It </ B> is sufficient, in particular, to act on only one of the parts to ensure a symmetrical movement of the two parts. The intermediate toothed part makes it possible to ensure movements of the two parts in the opposite direction, that is to say that either the two parts approach the plane of symmetry, or they depart from it.
<U>Dans</U> un mode de réalisation particulier, ladite pièce dentée intermédiaire est une double crémaillère dont au moins une extrémité est agencée pour déformer la garniture du coussin lors de ses déplacements. <U> In </ U> a particular embodiment, said intermediate toothed part is a double rack whose at least one end is arranged to deform the lining of the cushion during its movements.
On comprend que cette crémaillère se déplace vers l'arrière lorsque les deux parties sont rapprochées de l'axe de symétrie. Ainsi, elle facilite la tension de la garniture du côté où celle-ci a tendance<B>à</B> s'allonger et participe<B>à</B> la compression de cette dernière du côté où elle est comprimée. It is understood that this rack moves backwards when the two parts are close to the axis of symmetry. Thus, it facilitates the tension of the gasket on the side where it tends to extend and participates in the compression of the gasket on the side where it is compressed.
Plus particulièrement, l'enveloppe extérieure de l'appui-tête peut être élastique, au moins<U>dans</U> se partie susceptible d'être déformée par ladite crémaillère. More particularly, the outer shell of the headrest may be resilient, at least <U> in </ U> is likely to be deformed by said rack.
On évite ainsi les plis qui risqueraient d'être formés du côté où le coussin d'appui-tête est comprimé. On décrira maintenant,<B>à</B> titre d'exemple non limitatif, un mode de réalisation particulier de l'invention dans lequel<B>:</B> <B>-</B> La figure<B>1</B> est une vue en coupe horizontale d'un appui-tête selon l'invention<B>;</B> et <B>-</B> La figure 2 est une vue partielle en perspective du mécanisme de cet appui-tête. This avoids wrinkles that could be formed on the side where the pillow is compressed. We will now describe, as a non-limiting example, a particular embodiment of the invention in which: <B>: </ B> <B> - </ B> Figure <B > 1 </ B> is a horizontal sectional view of a headrest according to the invention <B>; </ B> and <B> - </ B> FIG. 2 is a partial perspective view of the mechanism of this headrest.
On voit<B>à</B> la figure<B>1</B> un coussin d'appui-tête<B>1,</B> supporté par une armature de montage 2 sur le dossier (non représenté) d'un siège de véhicule automobile. L'armature 2 comporte de façon connue deux broches tubulaires sensiblement verticales. Figure <B> at <B> 1 </ B> a <B> 1 Headrest Cushion, </ B> supported by a mounting frame 2 on the backrest (not shown) of a motor vehicle seat. The armature 2 comprises in known manner two substantially vertical tubular pins.
Le coussin<B>1</B> est composé d'un mécanisme qui sera décrit ci- après, surmoulé par exemple par un procédé "in situ" d'une mousse <B>3.</B> Une enveloppe 4,par exemple textile, forme l'extérieur du coussin. The cushion <B> 1 </ B> is composed of a mechanism which will be described hereinafter, overmolded for example by an "in situ" process of a foam <B> 3. </ B> An envelope 4, for example textile, forms the outside of the cushion.
Le coussin présente naturellement une forme générale en V dont la concavité est dirigée vers l'avant du véhicule (flèche AV). Le mécanisme intérieur au coussin comporte deux plaques allongées<B>5</B> et<B>6,</B> chacune étant montée<B>à</B> rotation sur une des broches de l'armature 2. Chaque plaque<B>5,6</B> comporte, du côté intérieur de l'axe de rotation par rapport au plan de symétrie<B>S</B> du coussin, une denture <B>7</B> en arc de cercle, centrée sur l'axe de rotation. Entre les deux dentures<B>7,</B> une pièce<B>8</B> comporte, de chaque côté du plan<B>S,</B> une crémaillère<B>9,</B> chacune des crémaillères<B>9</B> engrenant avec une des dentures<B>7.</B> La pièce<B>8</B> (non représentée<B>à</B> la figure 2) est guidée dans sa translation par deux plaques<B>10</B> et<B>11</B> montées sur les broches de l'armature, perpendiculairement<B>à</B> ces dernières. The cushion naturally has a general shape in V whose concavity is directed towards the front of the vehicle (arrow AV). The mechanism inside the cushion has two elongated plates <B> 5 </ B> and <B> 6, each <B> being rotated on one of the pins of the frame 2. Each plate <B> 5.6 </ B> comprises, on the inner side of the axis of rotation relative to the plane of symmetry <B> S </ B> of the cushion, a toothing <B> 7 </ B> in arc of a circle, centered on the axis of rotation. Between the two teeth <B> 7, <B> 8 </ B> has, on each side of the <B> S, </ B> a rack <B> 9, </ B> each of the <B> 9 </ B> racks meshing with one of the teeth <B> 7. <B> 8 </ B> (not shown <B> to </ B> Figure 2) is guided in its translation by two plates <B> 10 </ B> and <B> 11 </ B> mounted on the pins of the armature, perpendicularly <B> to </ B> them.
Ainsi, lorsque les deux ailes du coussin se déplacent dans la direction des flèches Fl, la pièce<B>8</B> est entraînée vers l'arrière, de sorte que son extrémité arrière 12 repousse vers l'arrière la matière comprise<B>à</B> l'arrière du coussin et favorise ainsi son extension. De même, la partie avant<B>13</B> de la pièce<B>8</B> tire vers l'arrière la matière figurant<B>à</B> l'avant du coussin, facilitant ainsi l'augmentation de sa concavité. Thus, when the two wings of the cushion move in the direction of the arrows Fl, the piece <B> 8 </ B> is driven backwards, so that its rear end 12 pushes back the material included < B> to </ B> the back of the cushion and thus promotes its extension. Similarly, the front part <B> 13 </ B> of the <B> 8 </ B> piece pulls the material <B> to the </ B> from the front of the cushion, making it easier to increase in concavity.
Inversement, lorsque les ailes du coussin sont déplacées dans le sens contraire de celui des flèches Fl, la pièce<B>8</B> se déplace vers l'avant, poussant dans cette direction la matière figurant<B>à</B> l'avant du coussin et tirant sur la matière figurant<B>à</B> l'arrière du coussin, facilitant ainsi la diminution de sa concavité. Conversely, when the wings of the cushion are moved in the opposite direction to that of the arrows Fl, the piece <B> 8 </ B> moves forward, pushing in this direction the material shown <B> to </ B > the front of the cushion and drawing on the material appearing <B> at </ B> the back of the cushion, thus facilitating the decrease of its concavity.
On observera que l'enveloppe du coussin comporte ici deux bandes élastiques 14 et<B>15,</B> chacune s'étendant de part et d'autre du plan de symétrie<B>S,</B> qui facilitent la déformation de l'enveloppe dans les zones où cette déformation est maximale.It will be observed that the envelope of the cushion comprises here two elastic bands 14 and <B> 15, </ B> each extending on either side of the plane of symmetry <B> S, </ B> which facilitate the deformation of the envelope in the zones where this deformation is maximum.
