Abstract

The device has a shell (1) supporting a padded part of a base and connected to a support, and a set of bars (6) integrated with the support and sliding in the shell in adjusting direction. A rod (2) is mounted on the shell and oriented in sliding direction, and is moved between a blocking position blocking one of the bars in a detent point (4) of a steering rack (3) and a releasing position releasing each bar. A returning unit returns the rod in the blocking position of the bars, and a control unit controls rotation of the rod.

Description

La présente invention concerne un dispositif de réglage de la position horizontale de l'assise d'un siège par rapport au support de ladite assise surmontant le pied du siège. Un tel dispositif est également dénommé dispositif de réglage de la profondeur de l'assise d'un siège.The present invention relates to a device for adjusting the horizontal position of the seat of a seat relative to the support of said seat overlying the foot of the seat. Such a device is also called a device for adjusting the depth of the seat of a seat.

Selon l'invention, le dispositif comporte :

  • une coque supportant la partie matelassée de l'assise et reliée au support ;
  • au moins une barre solidaire du support et apte à coulisser dans la coque, dans la direction du réglage ;
  • une tige montée sur la coque, orientée dans la direction du coulissement et dont au moins une portion comporte une crémaillère, ladite tige étant mobile en rotation entre une première position de blocage d'au moins une de ladite ou desdites barres dans une encoche de la crémaillère et une seconde position de libération de chaque barre ;
  • des moyens de rappel de la tige en position de blocage de chaque barre ; et
  • des moyens de commande de la rotation de la tige.
According to the invention, the device comprises:
  • a shell supporting the quilted portion of the seat and connected to the support;
  • at least one bar integral with the support and able to slide in the shell, in the direction of adjustment;
  • a rod mounted on the hull, oriented in the sliding direction and at least one portion of which comprises a rack, said rod being rotatable between a first locking position of at least one of said bar or bars in a notch of the rack and a second release position of each bar;
  • means for returning the rod in the locking position of each bar; and
  • means for controlling the rotation of the rod.

Le dispositif de l'invention fonctionne donc très simplement de la manière suivante : lorsque l'utilisateur actionne les moyens de commande de la rotation de la tige, celle-ci libère la ou les barres solidaires du support qu'elle bloquait jusqu'ici, rendant possible un coulissement de la coque d'assise par rapport audit support. Ce coulissement peut par exemple être effectué par l'utilisateur lorsqu'il est assis, en exerçant avec son corps une action vers l'avant ou vers l'arrière du siège tout en maintenant les moyens de commande actionnés.The device of the invention thus functions very simply as follows: when the user actuates the control means of the rotation of the rod, it releases the bars or bars integral with the support that it hitherto blocked, making it possible to slide the seat shell relative to said support. This sliding can for example be performed by the user when seated, exerting with his body an action forward or back of the seat while maintaining the control means actuated.

Ces derniers peuvent par exemple consister en une tringle orientée sensiblement perpendiculairement à la tige à crémaillère, dont une première extrémité est reliée à la tige par une liaison à rotation d'axe parallèle à et décalée de ladite tige, et dont la seconde extrémité est montée à un organe de commande apte à la déplacer selon un mouvement d'allure rectiligne pour faire pivoter la tige.The latter may for example consist of a rod oriented substantially perpendicular to the rack rod, a first end of which is connected to the rod by a rotationally connected connection axis parallel to and offset from said rod, and whose second end is mounted a control member adapted to move in a rectilinear movement to rotate the rod.

En d'autres termes, lorsque l'organe de commande est actionné, il déplace la tringle de manière à exercer une traction sur la liaison rotative décalée, provoquant du même coup la rotation de la tige supportant la crémaillère.In other words, when the control member is actuated, it moves the rod so as to exert traction on the offset rotary connection, thereby causing the rotation of the rod supporting the rack.

Plus précisément, selon une possibilité, la première extrémité de la tringle peut être munie d'une rotule apte à pivoter entre deux pattes parallèles dépassant radialement de la tige et munies de logements en regard pour loger la rotule.More specifically, according to one possibility, the first end of the rod may be provided with a ball pivotable between two parallel tabs projecting radially from the rod and provided with housings facing to accommodate the ball.

En l'occurrence, la rotule sert principalement à réaliser une liaison à rotation, même si les degrés de liberté supplémentaire qu'elle offre sont utiles par exemple pour rattraper des écarts dimensionnels. Plus généralement, l'utilisation d'une rotule permet de s'affranchir de la nécessité d'une grande précision dimensionnelle au moment de la réalisation des pièces, précision qui aurait évidemment un coût non négligeable.In this case, the ball is mainly used to make a rotational connection, even if the additional degrees of freedom it offers are useful for example to make up dimensional differences. More generally, the use of a ball makes it possible to overcome the need for a high dimensional accuracy at the time of production of the parts, a precision which would obviously have a significant cost.

De même, selon une configuration préférentielle, l'organe de commande peut consister en une manette à poussoir rotatif d'axe parallèle à celui de la tige à crémaillère, ledit poussoir comportant une excroissance dont l'extrémité libre comporte deux joues parallèles munies de logements en regard pour loger une rotule équipant la seconde extrémité de la tringle.Similarly, according to a preferred configuration, the control member may consist of a rotary push lever with an axis parallel to that of the rack rod, said push rod having a projection whose free end comprises two parallel cheeks provided with housings. facing to accommodate a ball equipping the second end of the rod.

L'utilisation d'une liaison de ce type à cette seconde extrémité présente les mêmes avantages que mentionnés auparavant, en termes de fabrication et de montage.The use of a link of this type at this second end has the same advantages as mentioned before, in terms of manufacture and assembly.

La rotation du poussoir, qui consiste en une surface sur laquelle s'exerce la poussée de l'utilisateur, est retransmise à l'excroissance et à son extrémité, entraînant la tringle à l'écart de la tige rotative, et permettant de faire pivoter cette dernière du fait du décalage que présente la première liaison à rotule.The rotation of the pusher, which consists of a surface on which the thrust of the user is exerted, is retransmitted to the protrusion and at its end, driving the rod away from the rotating rod, and to rotate the latter due to the offset that the first ball joint.

De préférence, les moyens de rappel peuvent consister en un ressort de torsion enroulé autour de la tige.Preferably, the return means may consist of a torsion spring wound around the rod.

L'utilisation de moyens de rappel au niveau de la tige permet de s'affranchir de l'emploi de moyens de rappel supplémentaires au niveau de l'organe de commande. Lorsque la tige est rappelée dans sa position initiale, bloquant au moins l'une des barres solidaires du support, la manette à poussoir est elle-même rappelée dans sa position de repos, prête à recevoir une nouvelle poussée de la part de l'utilisateur pour débloquer l'assise par rapport au support et au pied du siège.The use of return means at the stem makes it possible to dispense with the use of additional return means at the control member. When the rod is returned to its initial position, blocking at least one of the bars integral with the support, the push handle is itself recalled in its rest position, ready to receive a new thrust of the from the user to unlock the seat relative to the support and the foot of the seat.

Pour simplifier la configuration, la crémaillère couvre seulement une portion d'extrémité de la tige, en vue de bloquer une unique barre. Le déplacement par coulissement de ladite barre s'effectue donc selon une course qui couvre au maximum la longueur de la crémaillère.To simplify the configuration, the rack covers only one end portion of the rod, in order to block a single bar. The sliding displacement of said bar is therefore carried out in a race that covers the maximum length of the rack.

En fait, de préférence, le support comporte deux barres parallèles coulissantes dont les extrémités coulissent dans une direction perpendiculaire à l'axe des barres, dans des glissières de la coque disposées de part et d'autre et parallèlement à la tige.In fact, preferably, the support comprises two parallel sliding bars whose ends slide in a direction perpendicular to the axis of the bars, in sliders of the shell disposed on either side and parallel to the rod.

L'invention concerne également un siège muni d'un dispositif de réglage de la position horizontale de l'assise tel que décrit ci-dessus.The invention also relates to a seat provided with a device for adjusting the horizontal position of the seat as described above.

L'invention va à présent être décrite plus en détail, en référence aux figures annexées, pour lesquelles :

  • la figure 1 est une vue en perspective de la surface inférieure d'une coque supportant l'assise du siège, montrant le dispositif de réglage de la profondeur de l'assise en position bloquée par rapport à un support ;
  • la figure 2 représente, en vue perspective, la surface supérieure de la coque supportant l'assise ;
  • la figure 3 correspond à la figure 1, avec le dispositif de réglage de l'invention en position de libération de la coque par rapport au support ; et
  • la figure 4 montre une vue en perspective d'un support sur lequel est montée la coque de l'assise.
The invention will now be described in more detail, with reference to the appended figures, for which:
  • the figure 1 is a perspective view of the lower surface of a shell supporting the seat of the seat, showing the depth adjustment device of the seat in a locked position relative to a support;
  • the figure 2 represents, in perspective view, the upper surface of the shell supporting the seat;
  • the figure 3 corresponds to the figure 1 , with the adjustment device of the invention in the release position of the shell relative to the support; and
  • the figure 4 shows a perspective view of a support on which is mounted the seat shell.

En référence à la figure 1, la coque (1) supportant l'assise comporte une tige (2) dont l'une des extrémités présente une crémaillère (3) munie d'une série d'encoches (4). Cette tige (2) est montée rotative dans des guides (5) dépassant de la surface de la coque (1).With reference to the figure 1 , the shell (1) supporting the seat comprises a rod (2), one end of which has a rack (3) provided with a series of notches (4). This rod (2) is rotatably mounted in guides (5) protruding from the surface of the shell (1).

Dans la position de la tige (2) montrée en figure 2, une encoche (4) de la crémaillère (3) bloque une barre (6) dont les extrémités peuvent coulisser dans des glissières (7, 7') pratiquées dans la coque (1). Cette barre (6) est solidaire du support, par exemple montré en figure 4, support auquel est monté le pied du siège (non représenté). Ce support comporte d'ailleurs une seconde barre (6') également apte à coulisser dans les glissières (7, 7'), mais sur lesquelles ne s'exerce aucun moyen de blocage du type de la crémaillère (3). Un ressort de torsion (8) rappelle la tige (2) dans la position montrée en figure 1, aboutissant au verrouillage de l'assise sur le support (9).In the position of the rod (2) shown in figure 2 , a notch (4) of the rack (3) blocks a bar (6) whose ends can slide in slides (7, 7 ') formed in the shell (1). This bar (6) is integral with the support, for example shown in FIG. figure 4 , support to which is mounted the foot of the seat (not shown). This support also comprises a second bar (6 ') also able to slide in the slideways (7, 7'), but on which there is no locking means of the rack type (3). A torsion spring (8) recalls the rod (2) in the position shown in figure 1 , resulting in the locking of the seat on the support (9).

Les moyens de commande en rotation de la tige (2) consistent en une tringle (10) dont l'extrémité est montée rotative entre des pattes (11, 11') solidaires de la tige (2) et qui, actionnée par la manette à poussoir (12), permet de provoquer la rotation de ladite tige (2).The rotation control means of the rod (2) consist of a rod (10) whose end is rotatably mounted between lugs (11, 11 ') integral with the rod (2) and which, actuated by the lever to pusher (12), allows to cause the rotation of said rod (2).

Le fonctionnement de ces moyens de commande apparaît de manière plus explicite en figure 2. Cette figure montre la surface supérieure de la coque (1), surface en principe recouverte d'un matelassage donnant son confort à l'assise.The operation of these control means appears more explicitly in figure 2 . This figure shows the upper surface of the shell (1) surface in principle covered with a quilting giving comfort to the seat.

En l'espèce, le matelassage n'est pas représenté, et la tige (10) apparaît donc avec sa liaison à la manette à poussoir (12). Celle-ci pivote sensiblement au niveau de l'arête (13) de la coque (1) (voir figure 3), entraînant une protubérance (14) à l'extrémité de laquelle est reliée la tige (10). Cette protubérance (14) comporte deux joues supérieures (15, 15') munies de logements en regard dans lesquels l'extrémité en forme de rotule (16) de la tige (10) peut être clipsée. Ainsi, lorsque la manette (12) est pivotée vers le haut, en référence à la figure 2, l'extrémité supérieure de la protubérance (14) entraîne la tige (10) en un déplacement sensiblement rectiligne l'éloignant de la tige (2), entraînant un pivotement des pattes (11, 11') et par conséquent de la tige (2). La liaison entre la tringle (10) et les pattes (11, 11') se fait également à l'aide d'une rotule (17) logée dans deux logements en regard pratiqués dans ces pattes (11, 11'), comme cela apparaît en figure 3.In this case, the padding is not shown, and the rod (10) therefore appears with its connection to the push handle (12). It pivots substantially at the edge (13) of the shell (1) (see figure 3 ), causing a protrusion (14) at the end of which is connected the rod (10). This protuberance (14) comprises two upper cheeks (15, 15 ') provided with facing housings in which the ball-shaped end (16) of the rod (10) can be clipped. Thus, when the handle (12) is pivoted upwards, with reference to the figure 2 , the upper end of the protuberance (14) drives the rod (10) in a substantially rectilinear movement away from the rod (2), causing the tabs (11, 11 ') to pivot, and hence the rod ( 2). The link between the rod (10) and the tabs (11, 11 ') is also made by means of a ball joint (17) housed in two facing housings formed in these tabs (11, 11'), like this appears in figure 3 .

Lorsqu'on cesse d'agir sur la manette à poussoir (12), les moyens de rappel (8) ramènent la tige (2) dans sa position initiale, et par conséquent ladite manette (12) dans sa position de repos telle qu'illustrée en figure 1.When the pusher handle (12) is stopped from acting, the return means (8) return the stem (2) to its initial position, and consequently said lever (12) to its rest position such that illustrated in figure 1 .

Lorsque l'utilisateur entend déplacer la coque (1), qui est orientée telle que représentée en figure 2, par rapport au support (9) représenté en figure 4, il les débloque en appuyant sur la manette (12) de sorte que la tige (2) pivote et se retrouve dans sa position illustrée en figure 3. Une action dans un plan horizontal, par exemple réalisée par une poussée dans un sens ou dans l'autre, permet, selon la position de la barre (6) dans les glissières (7, 7') de modifier la position relative de la coque (1) par rapport au support (9).When the user intends to move the shell (1), which is oriented as shown in figure 2 , with respect to the support (9) represented in figure 4 , it releases them by pressing the handle (12) so that the rod (2) pivots and is found in its illustrated position in figure 3 . An action in a horizontal plane, for example made by a thrust in one direction or the other, allows, according to the position of the bar (6) in the slides (7, 7 ') to change the relative position of the hull (1) relative to the support (9).

Dès que la position désirée est atteinte, il suffit de relâcher la manette à poussoir (12), et la coque (1) se retrouve en position bloquée par rapport au support (9).As soon as the desired position is reached, simply release the push handle (12), and the shell (1) is in the locked position relative to the support (9).
