Abstract

The architecture has a backrest (3) mounted at the rear of a support along a transverse axis (4) to be moved between usage and folding positions along intermediate positions. A spring unit (10) e.g. hairpin spring, assists the folding of the backrest from the usage position. An elastic compressible unit (11) in the form of jack brakes the folding of the backrest from an intermediate position. The unit is arranged for providing a braking effort less than folding efforts induced by the unit (10) to place the backrest in the folding position without the manual support on the backrest.

Description

L'invention concerne une architecture de siège de véhicule automobile.The invention relates to a motor vehicle seat architecture.

II est connu de réaliser une architecture de siège de véhicule automobile à dossier rabattable, permettant un affaissement du siège lors du rabattement dudit dossier, et donc un gain d'espace de rangement, ladite architecture comprenant : • un support, par exemple sous forme d'un rail coulissant, solidaire du plancher du véhicule, • un dossier monté en rotation solidairement à l'arrière dudit support selon un premier axe transversal, de sorte à être mobile, selon une pluralité de positions intermédiaires, entre une position sensiblement verticale d'utilisation et une position sensiblement horizontale de rabattement, • une assise montée en rotation par rapport audit dossier selon un deuxième axe transversal disposé entre le haut dudit dossier et ledit premier axe, • une bielle dont une première extrémité est montée en rotation selon un troisième axe transversal à l'avant de ladite assise et dont la deuxième extrémité est montée en rotation selon un quatrième axe transversal solidairement à l'avant dudit support, • un moyen de verrouillage dudit dossier en position d'utilisation, • un moyen ressort d'assistance au rabattement dudit dossier depuis sa position d'utilisation, • un organe élastiquement compressible de freinage du rabattement dudit dossier à partir d'une première position intermédiaire.  It is known to realize a seat architecture of a motor vehicle with folding backrest, allowing a collapse of the seat during the folding of said folder, and thus a saving of storage space, said architecture comprising: a support, for example in the form of a sliding rail integral with the floor of the vehicle, a backrest rotatably mounted integrally at the rear of said support according to a first transverse axis, so as to be movable, according to a plurality of intermediate positions, between a substantially vertical position of use and a substantially horizontal position of folding, • a seat rotatably mounted relative to said backrest along a second transverse axis disposed between the top of said backrest and said first axis, • a connecting rod whose first end is rotatably mounted along a third axis transverse to the front of said seat and whose second end is mounted in rotation according to a fourth rième transverse axis integrally in front of said support, • a means for locking said backrest in the use position, • a means of assistance assisting the folding of said backrest from its position of use, • an elastically compressible braking member of the folding said folder from a first intermediate position.

Dans les réalisations connues, le moyen ressort exerce un couple permettant de propulser, après déverrouillage du moyen de verrouillage, le dossier depuis sa position d'utilisation vers une position voisine de la première position intermédiaire, l'utilisateur étant alors amené à appuyer sur le dossier pour contrer la force exercée par l'organe compressible et permettre audit dossier de se placer en position de rabattement, ce qui est peu ergonomique. 2 L'invention a pour but de pallier cet inconvénient.  In the known embodiments, the spring means exerts a torque for propelling, after unlocking of the locking means, the backrest from its position of use to a position close to the first intermediate position, the user then having to press on the folder to counter the force exerted by the compressible member and allow said folder to be placed in the folding position, which is uncomfortable. The object of the invention is to overcome this disadvantage.

A cet effet, l'invention propose une architecture de siège de véhicule automobile comprenant : • un support solidaire du plancher du véhicule, • un dossier monté en rotation solidairement à l'arrière dudit support selon un premier axe transversal, de sorte à être mobile, selon une pluralité de positions intermédiaires, entre une position sensiblement verticale d'utilisation et une position sensiblement horizontale de rabattement, ~o ^ une assise montée en rotation par rapport audit dossier selon un deuxième axe transversal disposé entre le haut dudit dossier et ledit premier axe, • une bielle dont une première extrémité est montée en rotation selon un troisième axe transversal à l'avant de ladite assise et dont la deuxième 15 extrémité est montée en rotation selon un quatrième axe transversal solidairement à l'avant dudit support, • un moyen de verrouillage dudit dossier en position d'utilisation, • un moyen ressort d'assistance au rabattement dudit dossier depuis sa position d'utilisation, 20 • un organe élastiquement compressible de freinage du rabattement dudit dossier à partir d'une première position intermédiaire, ledit organe étant agencé pour fournir un effort de freinage qui est inférieur aux efforts de rabattement induits par le moyen ressort de sorte à pouvoir placer ledit dossier en position de rabattement sans appui manuel sur ledit dossier. 25 Dans cette description, les termes de positionnement dans l'espace (transversal, avant, arrière, vertical, horizontal, latéral,...) sont pris en référence à l'architecture disposée dans le véhicule.  For this purpose, the invention proposes a motor vehicle seat architecture comprising: a support integral with the floor of the vehicle; a backrest rotatably mounted integrally at the rear of said support along a first transverse axis, so as to be movable; , according to a plurality of intermediate positions, between a substantially vertical position of use and a substantially horizontal position of folding, ~ o ^ a seat rotatably mounted relative to said folder along a second transverse axis disposed between the top of said folder and said first axis, • a connecting rod whose first end is rotatably mounted along a third axis transverse to the front of said seat and whose second end is rotatably mounted along a fourth transverse axis integrally in front of said support, • a locking means of said backrest in the position of use, • a spring means of assisting the folding of said d O-ring from its position of use, an elastically compressible braking member for folding said backrest from a first intermediate position, said member being arranged to provide a braking force which is less than the drawdown forces induced by the means. spring so as to place said folder in the folding position without manual support on said folder. In this description, the positioning terms in the space (transverse, front, rear, vertical, horizontal, lateral, ...) are taken with reference to the architecture arranged in the vehicle.

30 L'architecture proposée permet à l'utilisateur d'opérer un rabattement du dossier sans appuyer sur ledit dossier pour contrer la force exercée par l'organe compressible, ce qui apporte une ergonomie d'utilisation.  The proposed architecture allows the user to operate a folding of the folder without pressing on said folder to counter the force exerted by the compressible member, which provides ergonomic use.

D'autres particularités et avantages de l'invention apparaîtront dans la description qui suit, faite en référence aux figures jointes qui sont une représentation schématique latérale d'une architecture, selon un mode de réalisation, le dossier étant en position d'utilisation (figure la), en première position intermédiaire (figure lb), en position intermédiaire de rabattement supplémentaire au dessus de la troisième position (figure 1c) et en position de rabattement (figure 1d).  Other features and advantages of the invention will appear in the description which follows, made with reference to the attached figures which are a schematic lateral representation of an architecture, according to one embodiment, the folder being in the position of use (FIG. la), in the first intermediate position (FIG. 1b), in the intermediate position of additional folding above the third position (FIG. 1c) and in the folding position (FIG. 1d).

En référence aux figures, on décrit une architecture 1 de siège de véhicule automobile comprenant : • un support 2, par exemple sous forme de rail coulissant, solidaire du plancher du véhicule, • un dossier 3 monté en rotation solidairement à l'arrière dudit support selon un premier axe 4 transversal, de sorte à être mobile, selon une pluralité de positions intermédiaires, entre une position sensiblement verticale d'utilisation (figure la) et une position sensiblement horizontale de rabattement (figure 1d), • une assise 5 montée en rotation par rapport audit dossier selon un deuxième axe 6 transversal disposé entre le haut dudit dossier et ledit premier axe, • une bielle 7 dont une première extrémité est montée en rotation selon un troisième axe 8 transversal à l'avant de ladite assise et dont la deuxième extrémité est montée en rotation selon un quatrième axe 9 transversal solidairement à l'avant dudit support, • un moyen de verrouillage, non représenté, dudit dossier en position d'utilisation, • un moyen ressort 10 d'assistance au rabattement dudit dossier depuis sa position d'utilisation, • un organe 11 élastiquement compressible de freinage du rabattement dudit dossier à partir d'une première position intermédiaire (figure lb).  Referring to the figures, there is described a motor vehicle seat architecture 1 comprising: a support 2, for example in the form of a sliding rail, integral with the floor of the vehicle, a backrest 3 rotatably mounted integrally with the rear of said support along a first transverse axis 4, so as to be movable, according to a plurality of intermediate positions, between a substantially vertical position of use (Figure la) and a substantially horizontal position of folding (Figure 1d), • a seat 5 mounted in rotation relative to said backrest along a second transverse axis 6 disposed between the top of said backrest and said first axis, • a connecting rod 7 whose first end is rotatably mounted along a third axis 8 transverse to the front of said seat and whose second end is rotatably mounted along a fourth transverse axis 9 solidarily at the front of said support, a locking means, not repressed shown, said folder in the use position, • spring means 10 for assisting the folding of said folder from its position of use, • an elastically compressible member 11 for braking the folding of said folder from a first intermediate position ( figure lb).

L'organe est agencé pour fournir un effort de freinage qui est inférieur aux efforts de rabattement induits par le moyen ressort de sorte à pouvoir placer ledit dossier en position de rabattement sans appui manuel sur ledit dossier. Par efforts de rabattement induits, on entend les efforts exercés par le moyen ressort sur le dossier après déverrouillage du moyen de verrouillage, mais également tous les efforts s'appliquant sur le dossier lors de son rabattement, tels que son poids et les frottements.  The member is arranged to provide a braking force which is less than the folding forces induced by the spring means so as to place said folder in the folding position without manual support on said folder. Induced folding forces means the forces exerted by the spring means on the backrest after unlocking the locking means, but also all the efforts on the backrest during its folding, such as its weight and friction.

Selon la réalisation représentée, le moyen ressort 10 est sous forme d'un 10 ressort en épingle respectivement en appui sur le dossier 3 et l'assise 5.  According to the embodiment shown, the spring means 10 is in the form of a pin spring respectively bearing on the backrest 3 and the seat 5.

Le moyen ressort 10 est agencé de sorte à présenter une configuration inactive entre une deuxième position intermédiaire, non représentée, et la position de rabattement, de sorte à ne pas entraver le relèvement du dossier 3 en début de 15 relèvement.  The spring means 10 is arranged so as to present an inactive configuration between a second intermediate position, not shown, and the folding position, so as not to hinder the raising of the backrest 3 at the beginning of the bearing.

Selon la réalisation représentée, l'organe 11 compressible est sous forme d'un vérin.  According to the embodiment shown, the compressible member 11 is in the form of a jack.

20 Selon la réalisation représentée, les extrémités de l'organe 11 sont respectivement montées en rotation selon un cinquième axe 12 transversal solidaire de la partie avant du support 2 et un sixième axe 13 transversal solidaire de l'arrière de l'assise 5.  According to the embodiment shown, the ends of the member 11 are respectively mounted in rotation along a fifth transverse axis integral with the front portion of the support 2 and a sixth transverse axis 13 integral with the rear of the seat 5.

25 Le cinquième axe 12 est monté coulissant dans une lumière 14 sensiblement horizontale agencée de sorte à permettre un déplacement dudit axe depuis une position arrière, lorsque le dossier 3 est en position d'utilisation, à une position avant de butée lorsque ledit dossier est en première position intermédiaire, afin de permettre la compression de l'organe 11 lors du rabattement du dossier 3 au 30 delà de ladite première position.  The fifth axis 12 is slidably mounted in a substantially horizontal slot 14 arranged so as to allow said axis to move from a rear position, when the backrest 3 is in the position of use, to a forward thrust position when said backrest is in position. first intermediate position, to allow the compression of the member 11 when folding backrest 3 beyond said first position.

L'organe 11 est agencé de sorte à ne pas pouvoir effectuer un effort de relèvement du dossier 3 une fois mis en position de rabattement.  The member 11 is arranged so as not to be able to make an effort to raise the backrest 3 once put in the folding position.

Dans la réalisation représentée, le positionnement des cinquième 12 et sixième 13 axes est agencé de sorte que ledit sixième axe soit disposé, par rapport au plan passant par le quatrième 9 et ledit cinquième axes, au dessus dudit plan lorsque le dossier 3 est en position d'utilisation et en dessous dudit plan lorsque ledit dossier est en position de rabattement, ledit sixième axe étant disposé dans ledit plan lors du positionnement dudit dossier dans une troisième position intermédiaire, non représentée.  In the embodiment shown, the positioning of the fifth 12 and sixth 13 axes is arranged so that said sixth axis is disposed, relative to the plane passing through the fourth 9 and said fifth axis, above said plane when the backrest 3 is in position and below said plane when said backrest is in the folding position, said sixth axis being disposed in said plane when positioning said backrest in a third intermediate position, not shown.

Un tel agencement permet d'empêcher une action de l'organe 11 visant à relever le dossier 3 une fois rabattu.  Such an arrangement prevents an action of the body 11 to raise the backrest 3 once folded.

De façon non représentée, l'architecture 1 comprend en outre un moyen de verrouillage réversible, non représenté, du dossier 3 en position de rabattement, ledit moyen étant activé par positionnement dudit dossier en position de rabattement, de sorte à empêcher son relevage.  In a manner not shown, the architecture 1 further comprises a reversible locking means, not shown, the backrest 3 in the folding position, said means being activated by positioning said folder in the folding position, so as to prevent its lifting.
