Description
Dispositif d'assise pour véhicule automobile, comportant un appui-tête pivotant escamotable.Seat device for a motor vehicle, comprising a retractable pivoting headrest.
La présente invention est relative aux dispositifs d'assise pour véhicules automobiles, comportant des appuis-têtes pivotants escamotables. The present invention relates to seating devices for motor vehicles, comprising retractable pivoting headrests.
Plus particulièrement, l'invention concerne un dispositif d'assise pour véhicule automobile, comportant une assise, un dossier présentant au moins un côté dit extérieur, proche du côté dudit véhicule et orienté vers l'extérieur du véhicule, et au moins un appui-tête monté pivotant autour d'un axe de rotation sensiblement vertical proche du côté extérieur du dossier, cet appui-tête s'étendant sensiblement horizontalement entre une première extrémité proche de l'axe de rotation et une deuxième extrémité éloignée de l'axe de rotation, et l'appui-tête étant mobile entre, d'une part, une position d'utilisation où ledit appui-tête est disposé dans l'alignement du dossier, et d'autre part, une position escamotée où l'appui-tête s'étend vers l'arrière à partir dudit dossier, sensiblement perpendiculairement à ce dossier, le dispositif d'assise comportant en outre, d'une part, un dispositif de verrouillage pour bloquer l'appui-tête en position d'utilisation, et d'autre part, des moyens d'actionnement agissant sur le dispositif de verrouillage pour débloquer l'appui-tête à volonté,. More particularly, the invention relates to a seating device for a motor vehicle, comprising a seat, a back having at least one so-called external side, close to the side of said vehicle and oriented towards the outside of the vehicle, and at least one support- head mounted pivoting about a substantially vertical axis of rotation near the outside of the backrest, this headrest extending substantially horizontally between a first end close to the axis of rotation and a second end remote from the axis of rotation , and the headrest being movable between, on the one hand, a position of use where said headrest is arranged in alignment with the backrest, and on the other hand, a retracted position where the headrest extends rearward from said backrest, substantially perpendicular to this backrest, the seat device further comprising, on the one hand, a locking device for locking the headrest in the position of use on the other hand, actuating means acting on the locking device to unlock the headrest at will ,.
Le document EP-A-0 594 543 décrit un exemple d'un tel dispositif d'assise. Document EP-A-0 594 543 describes an example of such a seating device.
L'appui-tête divulgué dans ce document n'est maintenu dans sa position escamotée que par l'effet d'un ressort, de sorte que
- soit ce ressort est de faible puissance, auquel cas, lorsque l'appui-tête est dans sa position escamotée, cet appui-tête est mal maintenu et risque de balloter ou d'entrer en vibration, ce qui peut generer des bruits parasites à l'intérieur du véhicule,
- soit ce ressort est puissant, auquel cas ledit ressort entraîne un déplacement relativement violent de l'appui-tGte vers sa position escamotée lorsque l'appuitete est dans sa position d'utilisation et qu'on le débloque en agissant sur les moyens d'actionnement : ce déplacement violent peut être gênant pour les occupants du véhicule et peut même éventuellement blesser l'un de ces occupants ; de plus, l'appui-tête risque alors également de venir heurter violemment une vitre latérale du véhicule en fin de course, du fait de la forte sollicitation du ressort susmentionné.The headrest disclosed in this document is only held in its retracted position by the effect of a spring, so that
- Either this spring is of low power, in which case, when the headrest is in its retracted position, this headrest is poorly maintained and risks to wobble or enter into vibration, which can generate extraneous noise at inside the vehicle,
- Either this spring is powerful, in which case said spring causes a relatively violent displacement of the headrest towards its retracted position when the appuitete is in its position of use and that is released by acting on the means of actuation: this violent movement can be annoying for the occupants of the vehicle and can even possibly injure one of these occupants; in addition, the headrest then also risks violently striking a side window of the vehicle at the end of the race, due to the high stress of the aforementioned spring.
La présente invention a notamment pour but de pallier ces inconvénients. The present invention aims in particular to overcome these drawbacks.
A cet effet, selon l'invention, un dispositif d'assise du genre en question est essentiellement caractérisé en ce que le dispositif de verrouillage est également conçu pour bloquer l'appui-tête lorsqu'il est dans sa position escamotée. To this end, according to the invention, a seating device of the kind in question is essentially characterized in that the locking device is also designed to block the headrest when it is in its retracted position.
Grâce à ces dispositions, l'appui-tête est toujours parfaitement maintenu, qu'il soit dans sa position d'utilisation ou dans sa position escamotée, et il n'est donc pas nécessaire que cet appui-tête soit sollicité vers l'une de ses deux positions par un ressort puissant. Thanks to these provisions, the headrest is always perfectly maintained, whether in its position of use or in its retracted position, and it is therefore not necessary for this headrest to be biased towards one of its two positions by a powerful spring.
Dans des modes de réalisation préférés, on peut éventuellement avoir recours en outre à l'une et/ou à l'autre des dispositions suivantes
- l'appui-tête comprend un bras de support rigide qui tourbillonne sur un support fixe, ce bras étant lui-même solidaire d'une pièce de verrouillage rigide qui présente deux encoches situées à égale distance de l'axe de rotation, la pièce de verrouillage coopérant avec un verrou déplaçable entre, d'une part, une position active où il pénètre dans l'une des deux encoches pour bloquer l'appui-tete, et d'autre part, une position effacée où il permet le pivotement de l'appui-tête, le verrou étant sollicité vers sa position active par un ressort de verrou, les moyens d'actionnement étant conçus pour déplacer ce verrou dans sa position effacée, et la pièce de verrouillage comportant par ailleurs entre les deux encoches une surface d'appui lisse en arc de cercle qui est centrée sur l'axe de rotation et sur laquelle peut glisser le verrou lorsque l'appui-tete est déplacé entre sa position d'utilisation et sa position escamotée

III de la figure 2.On the drawings
FIG. 1 is a perspective view of a rear bench seat of a motor vehicle according to the invention, comprising two pivoting lateral headrests,
- Figure 2 is a cutaway view of the side appuitête signed on the right side of the seat of Figure 1, seen from the rear;
- And Figure 3 is a view in the direction
III of Figure 2.
La figure 1 représente un dispositif d'assise 1 tel qu'une banquette arrière de siège automobile, qui comprend une assise 2 et un dossier 3. FIG. 1 represents a seat device 1 such as a rear bench seat for a car seat, which comprises a seat 2 and a backrest 3.
Le dossier 3 comporte une portion centrale 4 rabattable (en un seul bloc ou en plusieurs parties rabattables indépendamment les unes des autres) et deux montants latéraux 5 fixes, qui sont solidaires de la caisse 6 du véhicule et qui sont proches chacun d'un côté 7 du véhicule. The backrest 3 comprises a central portion 4 which can be folded down (in a single block or in several parts which can be folded down independently of one another) and two fixed lateral uprights 5 which are integral with the body 6 of the vehicle and which are each close on one side 7 of the vehicle.
La banquette 1 comporte en outre deux appuis-têtes latéraux 8 qui sont montés en console respectivement sur les deux montants latéraux 5 de façon à pouvoir pivoter autour d'axes de rotation 9 sensiblement verticaux situés au niveau desdits montants latéraux 5. The bench seat 1 also comprises two lateral head restraints 8 which are mounted in a console respectively on the two lateral uprights 5 so as to be able to pivot around axes of rotation 9 substantially vertical located at the level of said lateral uprights 5.
Chaque appui-tête 8 s'étend sensiblement horizontalement entre, d'une part, une extrémité fixe 8a qui est située au niveau de l'axe de rotation 9 et qui est reliée au montant latéral 5 correspondant, et d'autre part, une extrémité libre 8 qui se déplace horizontalement lors du pivotement de l'appui-tête. Each headrest 8 extends substantially horizontally between, on the one hand, a fixed end 8a which is located at the axis of rotation 9 and which is connected to the corresponding lateral upright 5, and on the other hand, a free end 8 which moves horizontally during pivoting of the headrest.
Chaque appui-tete 8 est ainsi déplaçable entre d'une part, une position d'utilisation (représentée en traits pleins), où ledit appui-tête est disposé dans l'alignement vertical du dossier 3, et d'autre part, une position escamotée (représentée en traits mixtes) où l'appui-tete s'étend vers l'arrière à partir du dossier 3, sensiblement perpendiculairement à ce dossier. Each headrest 8 is thus movable between on the one hand, a position of use (shown in solid lines), where said headrest is disposed in the vertical alignment of the backrest 3, and on the other hand, a position retracted (shown in phantom) where the headrest extends rearward from the backrest 3, substantially perpendicular to this backrest.
Chaque appui-tête 8 est maintenu sélectivement soit dans sa position d'utilisation, soit dans sa position escamotée, au moyen d'un mécanisme de verrouillage qui sera décrit ci-après en regard des figures 2 et 3, et ledit appui-tête peut être déverrouillé par un utilisateur au moyen d'une manette 10 ou autre organe d'actionnement. Each headrest 8 is selectively held either in its use position or in its retracted position, by means of a locking mechanism which will be described below with reference to FIGS. 2 and 3, and said headrest can be unlocked by a user by means of a lever 10 or other actuating member.
Cette manette 10 est accessible uniquement sur le côté du montant latéral 5 qui est dirigé vers l'extérieur du véhicule, de façon à limiter les risques de déverrouillage involontaire de l'appui-tête. This lever 10 is accessible only on the side of the lateral upright 5 which is directed towards the outside of the vehicle, so as to limit the risks of involuntary unlocking of the headrest.
Comme représenté sur les figures 2 et 3, dans l'exemple considéré ici, chaque appui-tête inclut un bras de soutien métallique coudé 11 présentant une portion 12 qui s'étend verticalement selon l'axe de rotation 9 et qui, dans l'exemple représenté, tourillonne dans un manchon 13a en matière plastique, lui-même emboîté dans un support 13 solidaire du montant latéral correspondant 5. As shown in Figures 2 and 3, in the example considered here, each headrest includes a bent metal support arm 11 having a portion 12 which extends vertically along the axis of rotation 9 and which, in the example shown, journalled in a plastic sleeve 13a, itself fitted into a support 13 secured to the corresponding lateral upright 5.
De plus, le mécanisme de verrouillage 14 de cet appui-tête inclut
- une pièce de verrouillage métallique 15 qui présente une forme de portion de disque horizontal et qui est solidaire de la partie verticale 12 du bras 11, cette pièce de verrouillage présentant un bord extérieur 16 en forme d'arc de cercle centré sur l'axe 9, lequel bord 16 est encadré par deux encoches 17 débouchant radialement vers l'extérieur,
- un verrou métallique 18 qui est monté pivotant sur le support 13 autour d'un axe vertical 19 et qui est mobile entre, d'une part, une position active où un pion 20 appartenant à ce verrou pénètre dans l'une des deux encoches 17 de la pièce de verrouillage 15 pour verrouiller l'appui-tête, et d'autre part, une position effacée où le pion 20 n'interfère pas avec la pièce de verrouillage 15 et permet la rotation de l'appui-tête,
- un ressort de verrou 21 qui sollicite le verrou 18 vers sa position active,
- une bielle 22 qui s'étend horizontalement entre, d'une part, une première extrémité solidaire d'une tige rigide verticale 23 tourillonnant sur le support 13, et d'autre part, une deuxième extrémité dotée d'un pivot 24 qui coulisse dans une fente 25 appartenant au verrou 18, cette fente 25 étant formée dans une direction sensiblement radiale (et en tout cas non orthoradiale) par rapport à l'axe 19, la tige 23 étant solidaire de la manette 10,
- et un ressort de traction 26 de faible puissance qui est monté entre la pièce de verrouillage 15 et le support 13 pour solliciter l'appui-tête vers une position angulaire neutre qui correspond à une position du ressort 26 de faible puissance symbolisé par l'axe 27 sur la figure 2, cette position neutre de l'appui-tête 8 étant intermédiaire entre, d'une part, la position d'utilisation de l'appui-tête, qui correspond à la position du ressort 26 représentée sur la figure 2, et d'autre part, la position escamotée de l'appui-tête, qui correspond à une position du ressort 26 symbolisé par l'axe 28 sur la figure 2, et le ressort de traction 26 présentant une longueur minimale quand il est dans sa position 27 correspond à la position intermédiaire de l'appui-tête.In addition, the locking mechanism 14 of this headrest includes
a metallic locking piece 15 which has the shape of a horizontal disc portion and which is integral with the vertical part 12 of the arm 11, this locking piece having an outer edge 16 in the form of an arc of a circle centered on the axis 9, which edge 16 is framed by two notches 17 opening radially outward,
- A metal lock 18 which is pivotally mounted on the support 13 around a vertical axis 19 and which is movable between, on the one hand, an active position where a pin 20 belonging to this lock enters one of the two notches 17 of the locking piece 15 to lock the headrest, and on the other hand, a retracted position where the pin 20 does not interfere with the locking piece 15 and allows the rotation of the headrest,
a lock spring 21 which biases the lock 18 towards its active position,
- A connecting rod 22 which extends horizontally between, on the one hand, a first end secured to a vertical rigid rod 23 journalling on the support 13, and on the other hand, a second end provided with a pivot 24 which slides in a slot 25 belonging to the lock 18, this slot 25 being formed in a substantially radial direction (and in any case not orthoradial) relative to the axis 19, the rod 23 being integral with the lever 10,
- And a low power tension spring 26 which is mounted between the locking piece 15 and the support 13 to urge the headrest towards a neutral angular position which corresponds to a position of the low power spring 26 symbolized by the axis 27 in Figure 2, this neutral position of the headrest 8 being intermediate between, on the one hand, the position of use of the headrest, which corresponds to the position of the spring 26 shown in the figure 2, and on the other hand, the retracted position of the headrest, which corresponds to a position of the spring 26 symbolized by the axis 28 in FIG. 2, and the tension spring 26 having a minimum length when it is in its position 27 corresponds to the intermediate position of the headrest.
Grâce aux dispositions décrites ci-dessus, l'appui-tête est toujours maintenu dans sa position d'utilisation ou dans sa position escamotée au moyen du mécanisme de verouillage 14, qui évite tout ballottement ou toute vibration de l'appui-tête. Thanks to the arrangements described above, the headrest is always kept in its position of use or in its retracted position by means of the locking mechanism 14, which prevents any sloshing or any vibration of the headrest.
De plus, lorsqu'on souhaite déplacer cet appuitête de sa position d'utilisation à sa position escamotée ou inversement, il suffit
- d'actionner la manette 10, ce qui entraîne un déplacement relativement lent de l'appui-tête jusqu a sa position intermédiaire, sous l'effet du ressort de traction 26 de faible puissance,
- puis de déplacer manuellement llappui-tête jusqu'à sa position voulue, où il est à nouveau verrouillé automatiquement par le mécanisme de verrouillage 14. In addition, when one wishes to move this appuitête from its position of use to its retracted position or vice versa, it suffices
actuate the lever 10, which causes the headrest to move relatively slowly to its intermediate position, under the effect of the low-power tension spring 26,
- then manually move the headrest to its desired position, where it is again locked automatically by the locking mechanism 14.
