Abstract

The seat (1) has a jamb (13) guided in longitudinal translation on a mobile rail (3). An end of the jamb is connected to a locking unit (12), where another end of the jamb is equipped with a cam element (14) i.e. cam path. Another cam element (15) i.e. cam follower, is integrally connected to a front rod (9) and placed between two axes (10, 11). The cam elements are arranged such that the jamb is in a position to ensure locking of the locking unit when a backrest is in a use state. The folding back of the backrest causes a longitudinal translation of jamb to allow unlocking of locking unit.

Description

L'invention concerne un siège de véhicule automobile. Il est connu de réaliser un siège de véhicule automobile comprenant : - un rail fixe destinée à être fixé au sol dudit véhicule, - un rail mobile monté en translation longitudinale sur ledit rail fixe entre deux positions extrêmes, - une embase saillante vers le haut et solidaire de l'arrière dudit rail mobile, - un brancard de dossier monté en rotation en partie supérieure de ladite embase selon un premier axe transversal, de façon à pouvoir être mobile entre une configuration sensiblement verticale d'utilisation et une configuration sensiblement horizontale de rabattement, - un brancard d'assise monté en rotation par rapport audit brancard de dossier selon un deuxième axe transversal disposé entre le haut dudit brancard de dossier et ledit premier axe, - une bielle dont une première extrémité est montée en rotation selon un troisième axe transversal à l'avant dudit brancard d'assise et dont la deuxième extrémité est montée en rotation selon un quatrième axe transversal à l'avant dudit rail mobile, - un moyen de verrouillage dudit rail mobile par rapport audit rail fixe, ledit moyen étant solidaire dudit rail mobile. On connaît en particulier, notamment du document FR-2 914 593, une réalisation où le moyen de verrouillage est situé à proximité du quatrième axe et où le siège comprend en outre une came solidaire de la bielle et mobile en rotation autour dudit axe, ladite came étant agencée pour permettre une désactivation du moyen de verrouillage lors de sa rotation résultant du rabattement du dossier. The invention relates to a motor vehicle seat. It is known to make a motor vehicle seat comprising: - a fixed rail intended to be fixed to the ground of said vehicle, - a movable rail mounted in longitudinal translation on said fixed rail between two extreme positions, - a base projecting upwards and secured to the rear of said movable rail, - a backrest stretcher rotatably mounted in the upper part of said base according to a first transverse axis, so as to be movable between a substantially vertical configuration of use and a substantially horizontal configuration of drawdown - a seat stretcher rotatably mounted relative to said backrest stretcher along a second transverse axis disposed between the top of said backrest stretcher and said first axis, - a connecting rod whose first end is rotatably mounted along a third transverse axis at the front of said seat stretcher and whose second end is mounted in rotation according to a fourth transverse axis at the front of said movable rail, - a locking means of said movable rail relative to said fixed rail, said means being integral with said movable rail. Document FR-2 914 593 in particular discloses an embodiment in which the locking means is situated close to the fourth axis and where the seat furthermore comprises a cam secured to the connecting rod and movable in rotation about said axis, said cam being arranged to allow a deactivation of the locking means during its rotation resulting from folding the backrest.

Un tel déverrouillage permet notamment de ramener le siège vers l'arrière lors du rabattement de son dossier, ceci évitant audit dossier d'entrer en interférence avec un élément périphérique tel qu'un dossier de siège avant. Such unlocking allows in particular to bring the seat back when folding its back, this avoiding said file to interfere with a peripheral element such as a front seat back.

Or, dans le cas de sièges où le rail mobile peut effectuer une grande course entre les deux positions extrêmes, il peut s'avérer pertinent, pour éviter l'utilisation de rails fixes de très grande longueur, de ne pas disposer le moyen de verrouillage à proximité du quatrième axe, ledit moyen étant alors disposé vers l'arrière à distance dudit quatrième axe. Un tel agencement empêche de mettre en oeuvre le mode de déverrouillage connu du document cité ci-dessus. However, in the case of seats where the movable rail can make a great race between the two extreme positions, it may be relevant, to avoid the use of very long fixed rails, not to have the locking means near the fourth axis, said means then being disposed rearwardly away from said fourth axis. Such an arrangement prevents implementation of the known unlocking mode of the document cited above.

L'invention a pour but de proposer un agencement permettant de réaliser le déverrouillage d'un moyen de verrouillage situé vers l'arrière à distance du quatrième axe par rabattement du dossier. The object of the invention is to provide an arrangement for unlocking a locking means situated towards the rear away from the fourth axis by folding the backrest.

A cet effet, l'invention propose un siège de véhicule automobile comprenant : - un rail fixe destinée à être fixé au sol dudit véhicule, - un rail mobile monté en translation longitudinale sur ledit rail fixe entre deux positions extrêmes, - une embase saillante vers le haut et solidaire de l'arrière dudit rail mobile, - un brancard de dossier monté en rotation en partie supérieure de ladite embase selon un premier axe transversal, de façon à pouvoir être mobile entre une configuration sensiblement verticale d'utilisation et une configuration sensiblement horizontale de rabattement, - un brancard d'assise monté en rotation par rapport audit brancard de dossier selon un deuxième axe transversal disposé entre le haut dudit brancard de dossier et ledit premier axe, - une bielle dont une première extrémité est montée en rotation selon un troisième axe transversal à l'avant dudit brancard d'assise et dont la deuxième extrémité est montée en rotation selon un quatrième axe transversal à l'avant dudit rail mobile, - un moyen de verrouillage dudit rail mobile par rapport audit rail fixe, ledit moyen étant solidaire dudit rail mobile, ledit moyen étant disposé vers l'arrière à distance dudit quatrième axe et étant actionnable en déverrouillage par traction longitudinale, ledit siège comprenant en outre : - un jambage guidé en translation longitudinale sur ledit rail mobile, ledit jambage comprenant une première extrémité reliée audit moyen de verrouillage et une deuxième extrémité pourvue d'un premier élément de came, - un deuxième élément de came solidaire de ladite bielle avant, ledit élément étant disposé entre lesdits troisième et quatrième axes, lesdits éléments de came étant respectivement agencés de sorte que : - lorsque le dossier est en configuration d'utilisation, ledit jambage est dans une position assurant le verrouillage dudit moyen de verrouillage, - le rabattement dudit dossier provoque une translation longitudinale dudit jambage permettant le déverrouillage dudit moyen de verrouillage. Dans cette description, les termes de positionnement dans l'espace (haut, supérieur, longitudinal, transversal, latéral, avant, arrière, vertical, horizontal, .. . ) sont pris en référence au siège disposé dans le véhicule. Avec l'agencement proposé, on réalise le déverrouillage d'un moyen de verrouillage situé vers l'arrière à distance du quatrième axe par rabattement du dossier. For this purpose, the invention proposes a motor vehicle seat comprising: - a fixed rail intended to be fixed to the ground of said vehicle, - a movable rail mounted in longitudinal translation on said fixed rail between two extreme positions, - a protruding base towards the top and secured to the rear of said movable rail, - a backrest stretcher rotatably mounted in the upper part of said base according to a first transverse axis, so as to be movable between a substantially vertical configuration of use and a configuration substantially horizontal drawdown, - a seat stretcher rotatably mounted relative to said backrest stretcher along a second transverse axis disposed between the top of said backrest stretcher and said first axis, - a connecting rod whose first end is rotatably mounted according to a third transverse axis at the front of said seat stretcher and whose second end is mounted in rotation according to a fourth rth transverse axis at the front of said movable rail, - a means for locking said movable rail relative to said fixed rail, said means being integral with said movable rail, said means being disposed rearward away from said fourth axis and being operable in unlocking by longitudinal traction, said seat further comprising: - a jamb guided in longitudinal translation on said movable rail, said leg comprising a first end connected to said locking means and a second end provided with a first cam element, - a second cam member secured to said front link, said member being disposed between said third and fourth axes, said cam members being respectively arranged such that: - when the backrest is in use configuration, said leg is in a position ensuring the locking said locking means, - the folding of said folder causes a translat longitudinal ion of said leg for unlocking said locking means. In this description, the positioning terms in the space (top, top, longitudinal, transverse, lateral, front, rear, vertical, horizontal, ...) are taken in reference to the seat disposed in the vehicle. With the proposed arrangement, the unlocking of a locking means located towards the rear away from the fourth axis by folding the backrest.

En référence aux figures, on décrit un siège 1 de véhicule automobile comprenant : - un rail fixe 2 destiné à être fixé au sol dudit véhicule, - un rail mobile 3 monté en translation longitudinale sur ledit rail fixe entre deux positions extrêmes, de manière à permettre un réglage de la position longitudinale dudit siège, - une embase 4 saillante vers le haut et solidaire de l'arrière dudit rail mobile, - un brancard de dossier 5 monté en rotation en partie supérieure de ladite embase selon un premier axe 6 transversal, de façon à pouvoir être mobile entre une configuration sensiblement verticale d'utilisation et une configuration sensiblement horizontale de rabattement, - un brancard d'assise 7 monté en rotation par rapport audit brancard de dossier selon un deuxième axe 8 transversal disposé entre le haut dudit brancard de dossier et ledit premier axe, - une bielle 9 dont une première extrémité est montée en rotation selon un troisième axe 10 transversal à l'avant dudit brancard d'assise et dont la deuxième extrémité est montée en rotation selon un quatrième axe 11 transversal à l'avant dudit rail mobile, - un moyen de verrouillage 12 dudit rail mobile par rapport audit rail fixe, ledit moyen étant solidaire dudit rail mobile, ledit moyen étant disposé vers l'arrière à distance dudit quatrième axe et étant actionnable en déverrouillage par traction longitudinale, ledit siège comprenant en outre : - un jambage 13 guidé en translation longitudinale sur ledit rail mobile, ledit jambage comprenant une première extrémité reliée audit moyen de verrouillage et une deuxième extrémité pourvue d'un premier élément 14 de came, - un deuxième élément 15 de came solidaire de ladite bielle avant, ledit élément étant disposé entre lesdits troisième et quatrième axes, lesdits éléments de came étant respectivement agencés de sorte que : - lorsque le dossier est en configuration d'utilisation, ledit jambage est dans une position assurant le verrouillage dudit moyen de verrouillage, - le rabattement - ici partiel - dudit dossier provoque une translation longitudinale dudit jambage permettant le déverrouillage dudit moyen de verrouillage. Other features and advantages of the invention will appear in the description which follows, made with reference to the appended figures, in which: - Figure 1 is a partial side view of a seat according to one embodiment, the folder being in a configuration of 'use ; - Figure 2 is similar to Figure 1, the folder being partially folded, - Figure 3 is similar to Figure 1, the folder being in the folding configuration. With reference to the figures, there is described a seat 1 of a motor vehicle comprising: - a fixed rail 2 intended to be fixed to the ground of said vehicle, - a movable rail 3 mounted in longitudinal translation on said fixed rail between two extreme positions, so as to allow adjustment of the longitudinal position of said seat, - a base 4 projecting upwards and secured to the rear of said movable rail, - a backrest stretcher 5 rotatably mounted in the upper part of said base according to a first transverse axis 6, so as to be movable between a substantially vertical configuration of use and a substantially horizontal crimping configuration, - a seat stretcher 7 rotatably mounted relative to said backrest stretcher along a second transverse axis 8 disposed between the top of said stretcher backrest and said first axis - a connecting rod 9 whose first end is rotatably mounted along a third transverse axis 10 at the front of said seat stretcher and whose second end is rotatably mounted along a fourth axis 11 transverse to the front of said movable rail, - a locking means 12 of said movable rail relative to said fixed rail, said means being secured to said movable rail, said means being disposed rearward away from said fourth axis and being operable in longitudinal traction unlocking, said seat further comprising: - a leg 13 guided in longitudinal translation on said movable rail, said leg comprising a first end connected to said locking means and a second end provided with a first cam member 14; a second cam member secured to said front link, said member being disposed between said third and fourth axes, said cam members being respectively arranged so that: - when the file is in configuration of use, said jamb is dan s a position ensuring the locking of said locking means, - the folding - here partial - said folder causes a longitudinal translation of said jamb for unlocking said locking means.

Selon la réalisation représentée, le jambage 13 comprend deux lumières allongées 16,17 recevant respectivement en coulissement un doigt 19 issu du quatrième axe 11 et un doigt 18 issu du rail mobile 3, lesdits doigts se terminant chacun par une tête, non visible sur les figures, permettant de solidariser ledit jambage audit rail mobile tout en lui permettant un débattement longitudinal assurant son guidage en translation. Selon la réalisation représentée, les éléments de came 14,15 sont en outre agencés de sorte que la mise du dossier en configuration de rabattement provoque un retour du jambage 13 en position réalisant un reverrouillage du moyen de verrouillage 12. Un tel reverrouillage permet au siège 1 de rester bloqué en position longitudinale une fois que son dossier a atteint sa configuration de rabattement. According to the embodiment shown, the leg 13 comprises two elongate slots 16, 17 respectively slidingly receiving a finger 19 coming from the fourth axis 11 and a finger 18 coming from the movable rail 3, said fingers each ending in a head, not visible on the Figures, for securing said leg to said movable rail while allowing a longitudinal deflection ensuring its guidance in translation. According to the embodiment shown, the cam members 14, 15 are furthermore arranged so that the setting of the backrest in the folding configuration causes the leg 13 to return to its position by re-locking the locking means 12. Such re-locking allows the seat 1 to remain locked in the longitudinal position once its file has reached its folding configuration.

Selon la réalisation représentée, le premier élément 14 est un chemin de came et le deuxième élément 15 est un suiveur de came. Selon la réalisation représentée, le suiveur est sous la forme d'un doigt issu de la bielle 9, ledit doigt s'insérant dans une lumière prévue dans le jambage 13, ladite lumière formant chemin de came. According to the embodiment shown, the first element 14 is a cam path and the second element 15 is a cam follower. According to the embodiment shown, the follower is in the form of a finger coming from the connecting rod 9, said finger inserting into a light provided in the jamb 13, said light forming a cam path.

La lumière présente ici une largeur analogue à la section du doigt, de façon à permettre un asservissement optimisé de la position du jambage 13 par rapport à la position de la bielle 9. The light here has a width similar to the section of the finger, so as to allow optimized servocontrol of the position of the leg 13 relative to the position of the connecting rod 9.

Selon la réalisation représentée, le moyen de verrouillage 12 est actionnable en déverrouillage par traction longitudinale vers l'avant. Une telle traction vers l'avant est illustrée en figure 2 qui montre le déplacement du moyen de verrouillage 12 opéré par la traction exercée par le jambage 13 lorsque le dossier est partiellement rabattu. According to the embodiment shown, the locking means 12 can be actuated by unlocking by longitudinal traction towards the front. Such forward traction is illustrated in Figure 2 which shows the displacement of the locking means 12 operated by the traction exerted by the leg 13 when the folder is partially folded.
