Description

DISPOSITIF DE COMMANDE DE DEPLACENENT D'UNE ARMATURE DE SIEGE
MONTEE SUR DES GLISSIèRES DE REGLAGE
L'invention se rapporte à un dispositif de commande de déplacement d'une armature de siège fixée sur des glissières de réglage dont la partie postérieure porte l'axe d'articulation de biellettes montées, par ailleurs, à articulation sur lesdites glissières.DEVICE FOR CONTROLLING THE MOVEMENT OF A SEAT FRAME
MOUNTED ON ADJUSTMENT SLIDES
The invention relates to a device for controlling the movement of a seat frame fixed to adjustment slides, the rear part of which carries the axis of articulation of rods mounted, moreover, to articulation on said slides.

Dans ce casm crochet de verrouillage monté sur l'armature est destiné à immobiliser ladite armature en position d'utilisation du siège, et le déverrouillage de ce crochet permet le soulèvement de l'armature et son basculement vers l'avant.In this case, the locking hook mounted on the armature is intended to immobilize the said armature in the position of use of the seat, and the unlocking of this hook allows the armature to be raised and tilted forward.

L'invention s'applique particulièrement,bien que non exclusivement à des sièges avant de véhicules automobiles à une porte latérale ayant un emplacement de chargement derrière les sièges. The invention is particularly applicable, although not exclusively, to front seats of motor vehicles with a side door having a loading location behind the seats.

tes armatures ou les bases de ces sièges sont généralement mobiles pour assurer un mouvement d'avancement ou de recul sur deux glissières de réglage respectivement montées pour un mouvement analogue sur des coulisses rigidement fixées sur le plancher.your frames or the bases of these seats are generally movable to ensure a forward or backward movement on two adjustment slides respectively mounted for a similar movement on slides rigidly fixed on the floor.

Dans le but d'accéder plus aisément à l'emplacement de chargement, la publication FRA 74/31 344 propose un siège dans lequel la partie avant de l'armature de l'assise porte un palier support d'une coulisse auxiliaire guidée par rapport aux glissières mobiles du siège.In order to facilitate access to the loading location, the publication FRA 74/31 344 proposes a seat in which the front part of the seat frame carries a support bearing for an auxiliary slide guided relative to movable seat rails.

te basculement de ce type de siège est indépendant du déplacement relatif des glissières par rapport aux coulisses principales. De cette façon la position basculée du siège nta aucune influence sur la position des glissières dont les extrémités postérieures constituent une gêne au libre accès à la surface de chargement.te tilting of this type of seat is independent of the relative movement of the slides relative to the main slides. In this way the tilted position of the seat had no influence on the position of the slides, the rear ends of which hamper free access to the loading surface.

A partir de l'état de la technique précitée, l'invention se propose d'obtenir un siège déplaçable dont le basculement vers l'avant à partir de la position d'utilisation a pour effet de s'accompagner par un déplacement de même sens des glissières par rapport aux coulisses fixees au plancher du véhicule supportant ce siège.From the aforementioned state of the art, the invention proposes to obtain a movable seat whose tilting forward from the position of use has the effect of being accompanied by a movement in the same direction slides relative to the slides fixed to the floor of the vehicle supporting this seat.

Conformément à l'invention, les glissières portent des leviers de renvoi articulés, dont une extrémité porte une butée d'entratnement en rotation desdits leviers sous l'action de la biellette correspondante et dont l'autre extrémité est solidaire d'une bielle de réaction montée à articulation sur la coulisse fixe support de la glissière.According to the invention, the slides carry articulated return levers, one end of which carries a stop for driving said levers in rotation under the action of the corresponding link and the other end of which is secured to a reaction rod hinged mounted on the fixed slide support of the slide.

Dans le siège ainsi réalisé, on peut soulever l'armature jusqu'à ce que les biellettes entratnent les leviers de renvoi de façon à créer une tension de la bielle de réaction.In the seat thus produced, the armature can be lifted until the links drive the return levers so as to create tension in the reaction rod.

A la suite de cette tension, les leviers de renvoi sont immobilisés et le mouvement de basculement de l'armature entratne le mouvement longitudinal vers l'avant des glissières.Following this tension, the deflection levers are immobilized and the tilting movement of the armature causes the longitudinal movement forward of the slides.

Dans ce même but, l'extrémité inférieure des biellettes montées à articulation sur les glissières constitue le moyen d'actionnement du système de verrouillage des glissières par rapport aux coulisses.For this same purpose, the lower end of the rods mounted at articulation on the slides constitutes the means of actuation of the system for locking the slides with respect to the slides.

D'autres caractéristiques et avantages du dispositif ressortiront de la description d'un exemple de réalisation de celui-ci faite en référence au dessin annexé sur lequel les figures 1 et 2 sont des représentations schématiques des positions d'utilisation et de basculement du siège.Other characteristics and advantages of the device will emerge from the description of an exemplary embodiment thereof made with reference to the appended drawing in which FIGS. 1 and 2 are schematic representations of the positions of use and tilting of the seat.

Les figures 3 et 4 sont des vues en élévation de l'armature du siège et des glissières dans les positions correspondant aux figures 1 et 2.FIGS. 3 and 4 are elevation views of the seat frame and of the slides in the positions corresponding to FIGS. 1 and 2.

On voit sur le dessin le plancher 1 du véhicule portant des traverses 2, 3 sur lesquelles sont rigidement fixées des coulisses 4. tes parties antérieures des coulisses portent des paliers support 5 d'axes d'articulation 6 de bielles de réaction 7. Chaque bielle de reaction est percée d'une lumière d'ajustage 8 dans laquelle est monté à déplacement l'axe d'articulation 9 d'un levier de renvoi 10.We see in the drawing the floor 1 of the vehicle carrying crosspieces 2, 3 on which slides are rigidly fixed 4. your front parts of the slides carry support bearings 5 of articulation axes 6 of reaction rods 7. Each connecting rod of reaction is pierced with an adjustment light 8 in which the articulation axis 9 of a return lever 10 is mounted to move.

tes coulisses 4 portent- respectivement deux glissières 11 montées à déplacement longitudinal tandis qu'un système de verrouillage 12 assure soit l'immobilisation simultanée axiale des glissières 11 par rapport aux coulisses 4, soit leur déverrouillage ainsi que cela est bien connu.your slides 4 respectively carry two slides 11 mounted for longitudinal movement while a locking system 12 ensures either the simultaneous axial immobilization of the slides 11 relative to the slides 4, or their unlocking as is well known.

Chaque glissière 11 porte à sa partie antérieure l'axe d'articulation 13 d'une bielle support 14 de l'armature 15 du siège dont une extrémité est articulée autour d'un axe 24 porté par ladite armature.Each slide 11 carries at its front part the articulation axis 13 of a support rod 14 of the frame 15 of the seat, one end of which is articulated around an axis 24 carried by said frame.

La partie médiane de la glissière 11 porte un premier support 16 de l'axe d'articulation 17 du levier de renvoi 10 et un deuxième support 18 de l'axe d'articulation 19 d'une biellette 20 montee par ailleurs à articulation autour de l'axe 21 porté par un gousset 22 à la partie postérieure de l'armature 15
La partie supérieure du levier de renvoi 10 comporte une partie fonctionnelle constitutive d'une butée d'entratnement 23 de celui-ci sous l'action de la biellette correspondante 20.The middle part of the slide 11 carries a first support 16 of the hinge pin 17 of the return lever 10 and a second support 18 of the hinge pin 19 of a rod 20 mounted moreover with articulation around the axis 21 carried by a gusset 22 to the rear part of the frame 15
The upper part of the return lever 10 comprises a functional part constituting a drive stop 23 thereof under the action of the corresponding link 20.

L'extrémité inférieure de la biellette 20 porte une patte d'actionnement 20' du système de verrouillage 12 des glissières 11 par rapport aux coulisses 4.The lower end of the link 20 carries an actuating lug 20 ′ of the locking system 12 of the slides 11 relative to the slides 4.

ta glissière 11 porte par ailleurs une gâche en tôle 25 dans laquelle est engageable un crochet 26 monté à articulation autour d'un axe 27 porté par le gousset 22.your slide 11 also carries a sheet metal keeper 25 in which a hook 26 can be engaged which is articulated about an axis 27 carried by the gusset 22.

Un levier de manoeuvre 28 constitue le moyen d'entrarnement positif du crochet 26 à l'encontre d'un ressort de rappel 29 monté en tension entre deux ancrages respectivement portés par le verrou et par le gousset 22. Enfin, un ressort d'assistance 30 monté en compression entre la biellette 20 et le support 18,exerce un couple de commande sur la biellette 20 dans le sens du soulèvement de l'armature
Le fonctionnement du siège sera maintenant décrit en référence des figures 3 et 4. An operating lever 28 constitutes the positive drive means of the hook 26 against a return spring 29 tensioned between two anchors respectively carried by the latch and by the gusset 22. Finally, an assistance spring 30 mounted in compression between the link 20 and the support 18, exerts a control torque on the link 20 in the direction of lifting the frame
The operation of the seat will now be described with reference to FIGS. 3 and 4.

Sur la figure 3, la position de verrouillage du siège montre les différents organes du dispositif en position d'utilisation du siège.In FIG. 3, the seat locking position shows the various organs of the device in the seat use position.

te crochet 26 est en prise avec la gâche 25 portée par la glissière 11 pour une position de conduite ou d'utilisation du siège. torsque l'on désire accéder à la surface de chargement, il suffit d'actionner le levier 28 vers le haut, ce qui provoque le dégagement du crochet 26 et libère l'armature 15.te hook 26 is engaged with the keeper 25 carried by the slide 11 for a driving position or seat use. when it is desired to access the loading surface, it suffices to actuate the lever 28 upwards, which causes the hook 26 to be released and releases the armature 15.

Celle-ci peut se déplacer vers le haut sous l'action d'un effort de manoeuvre assisté par la détente du ressort 30.The latter can move upwards under the action of an operating force assisted by the relaxation of the spring 30.

L'armature se soulève en tournant autour des axes 13, 19. Les axes 24, 21 se déplacent suivant des arcs de cercle centrés sur les axes 13 et 19. Dans la course de la biellette 2P dans le sens de son soulèvement, la patte d'actionnement 20' coopère sur le,système de verrouillage 12 qui débraye la glissière 11 par rapport à la coulisse 4. Dans la phase suivante de sa course, la biellette 20 entre en contact avec les butées d1entranement 23 du levier de renvoi 10. Ce dernier pivote alors autour de l'axe 17 en tirant par son axe 9 la bielle de réaction 7.The frame lifts by turning around the axes 13, 19. The axes 24, 21 move in arcs of a circle centered on the axes 13 and 19. In the stroke of the 2P rod in the direction of its lifting, the tab actuator 20 'cooperates on the locking system 12 which disengages the slide 11 with respect to the slide 4. In the next phase of its travel, the rod 20 comes into contact with the drive stops 23 of the return lever 10. The latter then pivots around the axis 17 by pulling the reaction rod 7 by its axis 9.

L'ancrage rigide de la bielle 7 sur la coulisse 4 permet de générer un effort de réaction qui se traduit par un mouvement vers l'avant de la glissière 11. The rigid anchoring of the connecting rod 7 on the slide 4 makes it possible to generate a reaction force which results in a forward movement of the slide 11.
