Abstract

The seat has a mobile upper section (14) mounted on a fixed base (16) and has a turning mechanism (28) that allows its position to be reversed. The turning mechanism comprises a vertical pivot (30) connecting the upper section to the base, a slider (36) which acts as a bearing and can rotate about the pivot or move perpendicular to its axis (Z), and two cams (46, 48) on the base and upper section respectively. One of the cams has a profile which causes the upper section to follow a given trajectory as it rotates.

Description

La présente invention concerne un siège tournant, notamment pour véhicule ferroviaire.The present invention relates to a rotating seat, in particular for a vehicle rail.

On connaít déjà dans l'état de la technique un siège du type comprenant une partie supérieure mobile de réception d'au moins un occupant portée par une partie inférieure fixe formant piétement et des moyens de retournement de la partie supérieure d'avant en arrière et réciproquement.We already know in the prior art a seat of the type comprising a mobile upper part for receiving at least one occupant carried by a part fixed lower forming base and turning means of the upper part back and forth and vice versa.

Les sièges de ce type sont agencés en particulier dans les véhicules ferroviaires. Les moyens de retournement d'un siège permettent d'inverser l'orientation avant-arrière de ce siège de façon à placer ce siège et le(s) passager(s) qui l'occupe(nt) dans le sens de déplacement du véhicule, ceci quel que soit le sens dans lequel ce véhicule parcourt un trajet.Seats of this type are arranged in particular in vehicles railway. The means for turning a seat allow the orientation to be reversed front-rear of this seat so as to place this seat and the passenger (s) occupying it (s) in the direction of movement of the vehicle, regardless of the direction in which this vehicle travels a path.

Habituellement, les sièges d'un véhicule ferroviaire sont agencés à proximité d'une paroi latérale gauche ou droite de ce véhicule.Usually the seats of a railway vehicle are arranged close a left or right side wall of this vehicle.

L'espace entre les sièges et la paroi latérale voisine étant de préférence la plus réduite possible, le mouvement de retournement d'un siège d'avant en arrière (et inversement) par une simple rotation de la partie supérieure mobile du siège autour d'un axe vertical fixe est entravé par la paroi latérale. De ce fait, généralement le retournement d'un siège est réalisé, tout d'abord, en écartant la partie supérieure mobile de la paroi voisine du siège, puis en faisant tourner cette partie mobile autour d'un axe vertical et enfin en rapprochant cette partie mobile de la paroi voisine du siège.The space between the seats and the adjacent side wall is preferably the most possible, the movement of the seat from front to back (and vice versa) by a simple rotation of the movable upper part of the seat around a fixed vertical axis is hindered by the side wall. Because of this, generally the reversal a seat is made, first of all, by moving the movable upper part of the wall next to the seat, then by rotating this movable part around a vertical axis and finally by bringing this movable part closer to the wall next to the seat.

L'invention a pour but de proposer un siège, notamment pour véhicule ferroviaire, muni de moyens de retournement peu encombrants, légers et simples à manoeuvrer afin de permettre d'inverser rapidement l'orientation avant-arrière de l'ensemble des sièges d'un véhicule ferroviaire.The object of the invention is to provide a seat, in particular for a vehicle rail, equipped with space-saving turning means, light and simple to maneuver in order to quickly reverse the front-rear orientation of all the seats of a railway vehicle.

On a représenté sur la figure 1 un siège 10, selon l'invention, agencé dans un véhicule ferroviaire 12.FIG. 1 shows a seat 10, according to the invention, arranged in a rail vehicle 12.

Le siège 10 comporte une partie supérieure mobile 14 portée par une partie inférieure fixe 16 solidaire d'un plancher 18 du véhicule 12. La partie supérieure 14 est destinée à recevoir au moins un occupant, par exemple deux occupants comme dans le cas représenté sur la figure 1.The seat 10 comprises a movable upper part 14 carried by a part fixed lower 16 secured to a floor 18 of the vehicle 12. The upper part 14 is intended to receive at least one occupant, for example two occupants as in the case shown in figure 1.

De façon classique, la partie supérieure 14 comporte des matelassures d'assise 20 et de dossier 22 ainsi que des accoudoirs 24. La partie supérieure 24 est disposée à proximité d'une paroi latérale 26 du véhicule 12.Conventionally, the upper part 14 includes seat cushions 20 and backrest 22 as well as armrests 24. The upper part 24 is arranged at proximity of a side wall 26 of the vehicle 12.

Le siège 10 comprend également des moyens 28 de retournement de la partie supérieure 14 d'avant en arrière et réciproquement. Ces moyens de retournement 28 sont illustrés plus en détail sur les figures 2 à 9.The seat 10 also includes means 28 for turning over the part upper 14 from front to back and vice versa. These turning means 28 are illustrated in more detail in Figures 2 to 9.

Les moyens de retournement 28 comprennent un pivot 30 reliant la partie supérieure 14 et le piétement 16 du siège. L'axe géométrique Z de ce pivot 30, sensiblement vertical, est lié au piétement 16.The turning means 28 comprise a pivot 30 connecting the part upper 14 and the base 16 of the seat. The geometric axis Z of this pivot 30, substantially vertical, is linked to the base 16.

Le pivot 30 s'étend à travers deux parois sensiblement horizontales en vis-à-vis, l'une 32 mobile et l'autre 34 fixe. La première paroi 32, supérieure, délimite une armature de la partie supérieure 14. La seconde paroi 34, inférieure, délimite le piétement 16.The pivot 30 extends through two substantially horizontal walls facing each other, one 32 mobile and the other 34 fixed. The first wall 32, upper, defines a frame of the upper part 14. The second, lower wall 34 delimits the base 16.

Les moyens de retournement 28 comprennent également un coulisseau 36 monté déplaçable en translation, sensiblement perpendiculairement à l'axe Z, dans un rail rectiligne de guidage 38 ménagé dans la paroi supérieure 32. Le coulisseau 36 forme un palier monté déplaçable en rotation autour du pivot 30. La rotation du coulisseau 36 est facilitée par un roulement à aiguilles 40 intercalé entre le pivot 30 et le coulisseau 36 (voir figures 3 à 5).The turning means 28 also include a slide 36 mounted movable in translation, substantially perpendicular to the Z axis, in a rail straight guide 38 formed in the upper wall 32. The slide 36 forms a mounted bearing movable in rotation around the pivot 30. The rotation of the slide 36 is facilitated by a needle bearing 40 interposed between the pivot 30 and the slide 36 (see Figures 3 to 5).

Le pivot 30 s'étend à travers un trou oblong 42, allongé suivant une direction sensiblement parallèle à celle du rail de guidage 38, ménagé dans la paroi supérieure mobile 32. Le pivot 30 s'étend également à travers un orifice circulaire 44, formant palier, ménagé dans la paroi inférieure fixe 34.The pivot 30 extends through an oblong hole 42, elongated in a direction substantially parallel to that of the guide rail 38, formed in the upper wall mobile 32. The pivot 30 also extends through a circular orifice 44, forming a bearing, formed in the fixed bottom wall 34.

Les moyens de retournement 28 comportent en outre deux cames complémentaires portées respectivement par le piétement 16 et la partie supérieure 14.The turning means 28 further comprise two cams complementary carried respectively by the base 16 and the upper part 14.

Une première came forme un doigt 46, sensiblement vertical, solidaire de la paroi inférieure 34. La seconde came est délimitée par une rainure 48 formant guide ménagée dans la paroi supérieure 32. Cette rainure 48 s'étend sensiblement parallèlement à un plan perpendiculaire à l'axe Z. Le profil de la rainure 48 évolue de manière à imposer à la partie supérieure mobile 14 un trajet de retournement prédéterminé.A first cam forms a substantially vertical finger 46, integral with the bottom wall 34. The second cam is delimited by a groove 48 forming a guide formed in the upper wall 32. This groove 48 extends substantially parallel to a plane perpendicular to the Z axis. The profile of the groove 48 evolves so as to impose at the movable upper part 14 a predetermined turning path.

En se référant plus particulièrement à la figure 2, on voit que les extrémités de la rainure 48 sont alignées sensiblement dans un plan contenant l'axe Z et définissent en coopérant avec le doigt 46 les deux positions retournées l'une par rapport à l'autre de la partie supérieure 14 correspondant aux deux positions d'utilisation normale du siège représentées sur les figures 6 et 9.Referring more particularly to FIG. 2, it can be seen that the ends of the groove 48 are aligned substantially in a plane containing the axis Z and define in cooperating with finger 46 the two positions turned over with respect to each other of the upper part 14 corresponding to the two normal seat use positions shown in Figures 6 and 9.

La rainure 48 comprend deux tronçons rectilignes d'extrémité formant des rampes 48A,48B et un tronçon curviligne intermédiaire 48C.The groove 48 comprises two rectilinear end sections forming ramps 48A, 48B and an intermediate curvilinear section 48C.

Les rampes 48A,48B sont inclinées par rapport à la direction de déplacement en translation du coulisseau 36, si bien que ces rampes coopèrent avec le doigt 46 de manière à imposer à la partie supérieure 14 des déplacements résultant d'une combinaison d'un mouvement de rotation autour de l'axe Z et d'un mouvement de translation sensiblement perpendiculaire à cet axe Z.The ramps 48A, 48B are inclined relative to the direction of movement in translation of the slide 36, so that these ramps cooperate with the finger 46 of so as to impose on the upper part 14 displacements resulting from a combination a rotational movement around the Z axis and a translational movement substantially perpendicular to this Z axis.

Le tronçon curviligne 48C coopère avec le doigt 46 de façon à imposer à la partie supérieure 14 un déplacement en rotation autour de l'axe Z. The curvilinear section 48C cooperates with the finger 46 so as to impose on the upper part 14 a movement in rotation around the axis Z.

Le siège 10 comprend des moyens 50 de verrouillage de la partie supérieure 14 par rapport au piétement 16. Ces moyens de verrouillage 50 sont commandés de façon à être verrouillés ou libérés par un levier 52 muni d'une extrémité de manoeuvre 54 s'étendant de l'intérieur vers l'extérieur du piétement 16 à travers une ouverture 56 de ce dernier.The seat 10 comprises means 50 for locking the upper part 14 relative to the base 16. These locking means 50 are controlled so to be locked or released by a lever 52 provided with an operating end 54 extending from the inside to the outside of the base 16 through an opening 56 of this latest.

Les moyens de verrouillage 50 comprennent des moyens de serrage de deux faces de friction F1,F2 délimitant, respectivement, la paroi supérieure 32 mobile et la paroi inférieure 34 fixe. Ces faces de friction F1,F2 s'étendent sensiblement perpendiculairement à l'axe Z.The locking means 50 comprise means for clamping two friction faces F1, F2 delimiting, respectively, the movable upper wall 32 and the fixed bottom wall 34. These friction faces F1, F2 extend substantially perpendicular to the Z axis.

Les moyens de serrage, portés par le pivot 30, comprennent une tête d'extrémité de ce pivot, formant une mâchoire fixe 58, et une mâchoire mobile 60 montée coulissante axialement sur le pivot 30. La paroi supérieure mobile 32 et la paroi inférieure fixe 34 s'étendent entre les mâchoires fixe 58 et mobile 60.The clamping means, carried by the pivot 30, comprise a head end of this pivot, forming a fixed jaw 58, and a movable jaw 60 mounted sliding axially on the pivot 30. The movable upper wall 32 and the lower wall fixed 34 extend between the fixed 58 and mobile 60 jaws.

Un patin anti-friction, porté par la paroi supérieure mobile 32 est en contact avec la mâchoire fixe 58 afin de minimiser les frottements entre la mâchoire fixe 58 et la paroi supérieure mobile 32 lorsque cette dernière se déplace perpendiculairement à l'axe Z.An anti-friction pad, carried by the movable upper wall 32 is in contact with the fixed jaw 58 in order to minimize the friction between the fixed jaw 58 and the movable upper wall 32 when the latter moves perpendicular to the axis Z.

La mâchoire mobile 60, déformable élastiquement dans la direction de l'axe Z, est déplaçable entre une position décomprimée de séparation des faces de friction F1,F2, telle que représentée sur les figures 3 et 4, et une position comprimée de serrage de ces faces de friction F1, F2, telle que représentée sur la figure 5.The movable jaw 60, elastically deformable in the direction of the axis Z, is movable between a decompressed position of separation of the friction faces F1, F2, as shown in Figures 3 and 4, and a compressed position for clamping these friction faces F1, F2, as shown in FIG. 5.

Les positions décomprimée et comprimée de la mâchoire mobile 60 correspondent, respectivement, aux positions de déverrouillage et de verrouillage des moyens 50.The decompressed and compressed positions of the movable jaw 60 correspond, respectively, to the unlocking and locking positions of the means 50.

La mâchoire mobile 60 comprend, par exemple, deux rondelles élastiques 64,66 intercalées entre deux rondelles planes 68,70. Les rondelles élastiques 64,66 sont par exemple du type Belleville.The movable jaw 60 comprises, for example, two elastic washers 64.66 inserted between two flat washers 68.70. The 64.66 spring washers are for example of the Belleville type.

La mâchoire mobile 60 est déplaçable et compressible axialement par coopération avec une came 72 articulée sur le pivot 30, éventuellement avec un jeu dans la direction de l'axe Z, autour d'un axe géométrique X sensiblement perpendiculaire à cet axe Z.The movable jaw 60 is displaceable and compressible axially by cooperation with a cam 72 articulated on the pivot 30, possibly with a play in the direction of the Z axis, around a geometric axis X substantially perpendicular to this Z axis.

On notera que la came 72 forme, de préférence, une extrémité articulée du levier de commande 52 opposée à son extrémité de manoeuvre 54. It will be noted that the cam 72 preferably forms an articulated end of the control lever 52 opposite its operating end 54.

On notera également que la came 72 prend appui sur une rondelle plane 74 immobilisée axialement par un écrou d'arrêt 76 vissé sur l'extrémité du pivot 30 opposée à la mâchoire fixe 58.It will also be noted that the cam 72 is supported on a flat washer 74 axially immobilized by a stop nut 76 screwed onto the end of the pivot 30 opposite to the fixed jaw 58.

Afin de faciliter le déplacement de la partie supérieure 14 par rapport au piétement 16, la face de friction F1 portée par la paroi supérieure mobile 32 comporte des organes roulants représentés notamment sur la figure 4. De préférence, ces organes, par exemple au nombre de trois, comportent chacun une bille 78. Chaque bille 78 est déplaçable sensiblement parallèlement à l'axe Z entre une position saillante d'entretoisement des faces de friction F1,F2, dans laquelle la bille 78 est en contact roulant avec la face de friction F2 du piétement (voir figure 4), et une position escamotée dans laquelle les faces de friction F1,F2 sont en contact entre elles de manière à immobiliser la partie supérieure 14 du siège par rapport au piétement 16.In order to facilitate the movement of the upper part 14 relative to the base 16, the friction face F1 carried by the movable upper wall 32 includes rolling bodies shown in particular in Figure 4. Preferably, these bodies, by example three in number, each have a ball 78. Each ball 78 is movable substantially parallel to the Z axis between a projecting position bracing of the friction faces F1, F2, in which the ball 78 is in contact rolling with the friction face F2 of the base (see Figure 4), and a retracted position in which the friction faces F1, F2 are in contact with each other so as to immobilize the upper part 14 of the seat relative to the base 16.

Les billes 78 sont rappelées élastiquement en position saillante par des ressorts 80 sollicitant les organes roulants.The balls 78 are resiliently returned to the projecting position by springs 80 urging the rolling members.

On décrira ci-dessous les principales étapes du retournement du siège 10 selon l'invention, en se référant notamment aux figures 6 à 9.The main stages of turning the seat 10 according to will be described below. the invention, with particular reference to Figures 6 to 9.

Initialement, la partie supérieure 14 du siège est dans une première position normale d'utilisation de ce siège telle que représentée sur la figure 6. Les moyens de verrouillage 50 sont activés (levier de commande 52 en position haute) de manière à immobiliser la partie supérieure 14 par rapport au piétement 16.Initially, the upper part 14 of the seat is in a first position normal use of this seat as shown in Figure 6. The means of lock 50 are activated (control lever 52 in high position) so as to immobilize the upper part 14 relative to the base 16.

Pour retourner le siège 10, l'opérateur abaisse tout d'abord le levier de commande 52 (de préférence avec le pied), jusqu'à sa position basse représentée sur la figure 3, de manière à libérer les moyens de verrouillage 50. La partie supérieure mobile 14 peut alors se déplacer par rapport au piétement 16.To return the seat 10, the operator first of all lowers the lever control 52 (preferably with the foot), to its low position shown on the Figure 3, so as to release the locking means 50. The movable upper part 14 can then move relative to the base 16.

Puis, l'opérateur entraíne manuellement la partie supérieure 14 du siège en imprimant à cette dernière un mouvement général de retournement parallèle à un plan horizontal, dans le sens horaire en se référant aux figures 7 à 9.Then, the operator manually drives the upper part 14 of the seat giving the latter a general reversal movement parallel to a plane horizontal, clockwise with reference to Figures 7 to 9.

Le doigt de came 46 coopère alors avec la rampe 48A ce qui a pour effet d'imposer à la partie supérieure 14 un mouvement combiné de translation, tendant à écarter la partie supérieure 14 de la paroi latérale voisine 26 dans une direction transversale à l'axe Z, et de rotation autour de cet axe Z (voir figure 7). Le déplacement en translation de la partie supérieure 14 résulte du déplacement du coulisseau 36 dans son rail de guidage 38. Le déplacement de ce coulisseau 36 est de préférence assisté par un ressort de compression 82 (voir notamment figure 3) intercalé entre des extrémités en vis-à-vis de ce coulisseau et du rail 38. Le déplacement en rotation de la partie supérieure 14 résulte de la rotation du coulisseau 36 autour du pivot 30.The cam finger 46 then cooperates with the ramp 48A which has the effect to impose on the upper part 14 a combined translational movement, tending to move the upper part 14 away from the adjacent side wall 26 in one direction transverse to the Z axis, and rotation about this Z axis (see Figure 7). Moving in translation of the upper part 14 results from the displacement of the slide 36 in its guide rail 38. The movement of this slide 36 is preferably assisted by a compression spring 82 (see in particular Figure 3) interposed between opposite ends of this slide and the rail 38. The rotational movement of the upper part 14 results from the rotation of the slide 36 around the pivot 30.

Le doigt de came 46 coopère ensuite avec le tronçon curviligne 48C ce qui a pour effet de faire pivoter la partie mobile 14 autour de l'axe Z de façon à amener cette partie 14 dans la position représentée sur la figure 8. On notera que les positions de la partie supérieure mobile 14 représentées sur les figures 7 et 8 sont sensiblement symétriques par rapport à un plan vertical transversal du véhicule.The cam finger 46 then cooperates with the curvilinear section 48C which has to rotate the movable part 14 around the axis Z so as to bring this part 14 in the position shown in Figure 8. Note that the positions of the mobile upper part 14 shown in FIGS. 7 and 8 are substantially symmetrical with respect to a transverse vertical plane of the vehicle.

Enfin, le doigt de came 46 coopère avec la seconde rampe 48B ce qui a pour effet d'achever le retournement de la partie supérieure mobile 14 et de rapprocher cette partie 14 avec la paroi latérale voisine 26, comme cela est représenté sur la figure 9.Finally, the cam finger 46 cooperates with the second ramp 48B which has for effect of completing the reversal of the movable upper part 14 and bringing this part 14 with the adjacent side wall 26, as shown in FIG. 9.

Pour immobiliser la partie supérieure mobile 14 dans la seconde position normale d'utilisation du siège représentée sur la figure 9, l'opérateur soulève le levier de commande 52, jusqu'à sa position telle que représentée sur la figure 5, de manière à activer de nouveau les moyens de verrouillage 50.To immobilize the movable upper part 14 in the second position normal use of the seat shown in Figure 9, the operator raises the lever control 52, to its position as shown in Figure 5, so that re-activate the locking means 50.

Pour replacer le siège dans sa position illustrée sur la figure 6, l'opérateur déplace la partie supérieure 14 selon un trajet obligatoirement inverse à celui décrit précédemment. Ainsi, lorsque la partie supérieure 14 et le piétement 16 du siège sont équipés de moyens électriques (par exemple des moyens de motorisation destinés à entraíner la partie supérieure 14), les câbles électriques s'étendant le cas échéant entre cette partie 14 et ce piétement 16 ne risquent pas de s'enrouler accidentellement autour du pivot 30 à la suite de rotations successives de la partie supérieure 14 toujours dans le même sens.To return the seat to its position illustrated in Figure 6, the operator moves the upper part 14 according to a path necessarily opposite to that described previously. Thus, when the upper part 14 and the base 16 of the seat are equipped with electrical means (for example motorization means intended for drive the upper part 14), the electric cables extending if necessary between this part 14 and this base 16 are not likely to accidentally wrap around the pivot 30 following successive rotations of the upper part 14 still in the Same direction.

Parmi les avantages de l'invention, on notera que celle-ci permet à un opérateur de retourner très facilement un siège en entraínant la partie supérieure mobile de ce dernier dans un mouvement général de retournement, ceci sans que ce mouvement soit entravé par la paroi latérale du véhicule proche du siège.Among the advantages of the invention, it will be noted that it allows a operator very easily turn over a seat by driving the movable upper part of the latter in a general reversal movement, without this movement being hindered by the side wall of the vehicle near the seat.

Par ailleurs, ce mouvement peut être automatisé facilement à l'aide de moyens de commande et de contrôle classiques (verins(s), moteur(s) rotatif(s), etc....).Furthermore, this movement can be easily automated using means conventional command and control (cylinders, rotary motor (s), etc.).

La commande pourrait être locale (par exemple un bouton-poussoir de commande par siège), ou centralisée pour l'ensemble ou une partie des sièges d'un véhicule.The command could be local (for example a push button of seat control), or centralized for all or part of the seats of a vehicle.
