Abstract

The chair-back adjustment mechanism has two fittings (11,12), one mounted to the base of the back of the chair and one mounted to the rear of the seat. The fitting on the back has a circular aperture with a pair of seats (36,37) cut into the periphery. These receive the lug (22) of a locking element which is operated by a slotted disc controlled by an operating lever (28). The key is moved by the lever into and out of engagement with the seats in the seat back to allow it to pivot w.r.t. the seat.

Description

Mécanisme de réglage et de commande d'inclinaison d'un dossier de siège. Adjustment and tilt control mechanism for a seat back.

L'invention concerne un mécanisme de réglage et de commande de l'inclinaison d'un dossier de siège notamment pour véhicules de transport de passagers qui comporte une ferrure solidaire du dossier, une ferrure solidaire de l'assise du siège, un secteur de couronne denté lié à l'une des ferrures, un organe de verrouillage denté à déplacements guidés appliqué contre le secteur de couronne denté par une coulisse fixée à l'autre ferrure, ledit organe de verrouillage étant percé d'une lumière traversée par l'axe de commande du mécanisme.Le problème non résolu pour de tels mécanismes de réglage réside dans le fait que l'on ne peut obtenir le déplacement angulaire de la ferrure mobile par rapport à la ferrure fixe avec la possibilité de la ramener exactement dans la position de réglage initiale qui correspond à la position de confort souhaitée de l'occupant du siège.The invention relates to a mechanism for adjusting and controlling the inclination of a seat back, in particular for passenger transport vehicles, which comprises a fitting secured to the back, a fitting secured to the seat cushion, a crown sector. toothed linked to one of the fittings, a toothed locking member with guided movements applied against the ring gear sector by a slide fastened to the other fitting, said locking member being pierced with a light through which the axis of The unresolved problem for such adjustment mechanisms lies in the fact that it is not possible to obtain the angular displacement of the movable fitting relative to the fixed fitting with the possibility of bringing it exactly back into the adjustment position. initial which corresponds to the desired comfort position of the seat occupant.

Pour résoudre ce problème on a déjà proposé des dispositifs de déverrouillage du dossier utilisant deux mécanismes distincts dotés chacun d'un organe de commande et permettant l'un, le réglage en position de la ferrure mobile et l'autre le déplacement du dossier lié à cette ferrure et son retour dans la position de réglage.To solve this problem, backrest unlocking devices have already been proposed using two separate mechanisms, each provided with a control member and allowing one, the position adjustment of the movable fitting and the other the movement of the backrest linked to this fitting and its return to the adjustment position.

Ces dispositifs sont par conséquent d'une utilisation complexe du fait de l'emploi de deux commandes distinctes et diautre part d'un prix de revient élevé dû à la multiplicité des organes qui constituent ces mécanismes.These devices are therefore of complex use due to the use of two separate controls and on the other hand of a high cost price due to the multiplicity of organs which constitute these mechanisms.

C'est pourquoi l'invention a pour but, la réalisation d'un mécanisme unique qui remplit les deux fonctions avec un minimum d'organes et une commande commune.This is why the invention aims, the realization of a single mechanism which fulfills the two functions with a minimum of organs and a common command.

A cet effet elle a pour objet un mécanisme du type prédéfini, caractérisé par le fait que l'autre ferrure est partiellement conformée ou découpée en au moins un logement qui reçoit verrou asservi au moyen de commande du mécanisme et dont le mouvement est en mouvement rectiligne guidé par une coulisse coopérant avec le dit moyen de commande en vue de l'accouplement de ladite coulisse avec la ferrure et de désaccouplement de celle-ci.For this purpose it relates to a mechanism of the predefined type, characterized by the fact that the other fitting is partially shaped or cut into at least one housing which receives a lock controlled by the mechanism control and whose movement is in rectilinear movement guided by a slide cooperating with said control means for coupling of said slide with the fitting and uncoupling of the latter.

Selon le mode préférentiel de réalisation du mécanisme les moyens de commande d'accouplement sont constitués par un disque rotatif plan solidaire en rotation de l'axe de commande du mécanisme portant deux cavités partiellement centrées sur l'axe de commande avec une portion excentrée, dans lesquelles sont respectivement engagés deux axes de manoeuvre respectivement portés par l'organe de verrouillage denté et par le verrou.According to the preferred embodiment of the mechanism, the coupling control means are constituted by a plane rotary disc integral in rotation with the control axis of the mechanism carrying two cavities partially centered on the control axis with an eccentric portion, in which are respectively engaged two operating axes respectively carried by the toothed locking member and by the latch.

Une forme de réalisation du mécanisme de réglage est représenté à titre d'exemple non limitatif aux dessins annexés.An embodiment of the adjustment mechanism is shown by way of non-limiting example in the accompanying drawings.

La figure 1 est une vue de profil du mécanisme en position désaccouplée de la ferrure solidaire du dossier.Figure 1 is a side view of the mechanism in the uncoupled position of the fitting integral with the backrest.

La figure 2 est une vue de profil du mécanisme en position de réglage du dossier par rapport au secteur de couronne denté.Figure 2 is a side view of the mechanism in the backrest adjustment position relative to the ring gear sector.

La figure 3 est une vue éclatée du mécanisme.Figure 3 is an exploded view of the mechanism.

Le mécanisme de réglage 10 conforme à l'invention comprend une ferrure il solidaire d'un élément de l'armature i du dossier du siège et une ferrure 12 solidaire d'un élément de l'armature 2 de l'assises La ferrure 12 porte un secteur de couronne denté 13 rapporté au moyen de vis 14 mais pouvant être obtenu directement lors de l'emboutissage et du découpage de celle-ci. La ferrure 12 porte par ailleurs une fenêtre 15 de configuration arquée dont les flancs constituent des butées à l'or- gane de verrouillage 16.Ce dernier possède une configuration générale étagée dont la partie dentée 17 est engagée dans la fenêtre et s'étend radialement vers le secteur de couronne denté 13, tandis que la partie guidée 18 est disposée dans la mortaise radiale 20 formant coulisse prévue sur l'une des faces d'un anneau support circulaire 19 dont l'autre face porte également une mortaise 21 formant coulisse qui constitue le guide d'un deuxième verrou 22. L'organe de verrouillage 16 et le verrou 22 possèdent respectivement un pion de manoeuvre 23, 24 et une lumière 25, 26 qui stétend radialement en direction de la partie dentée 17 de l'organe de verrouillage 16 et vers le verrou 22.Les lumières 25, 26 sont respectivement traversées par l'axe de commande 27 du mécanisme et autorisent les déplacements radiaux des organes 16, 22 par rapport à l'axe 27 sous l'action d'un mouvement de rotation communiqué audit axe 27 par une poignée 28.The adjustment mechanism 10 according to the invention comprises a fitting 11 secured to an element of the frame i of the seat back and a fitting 12 secured to an element of the frame 2 of the seats The fitting 12 carries a toothed ring sector 13 attached by means of screws 14 but which can be obtained directly during stamping and cutting thereof. The fitting 12 also carries a window 15 of arcuate configuration, the sides of which constitute stops at the locking member 16. The latter has a generally stepped configuration, the toothed portion 17 of which is engaged in the window and extends radially. towards the ring gear sector 13, while the guided part 18 is disposed in the radial mortise 20 forming a slide provided on one of the faces of a circular support ring 19 the other face of which also carries a mortise 21 forming a slide which constitutes the guide of a second latch 22. The locking member 16 and the latch 22 respectively have an operating pin 23, 24 and a slot 25, 26 which extends radially in the direction of the toothed portion 17 of the member locking 16 and towards the locking 22. The openings 25, 26 are respectively crossed by the control axis 27 of the mechanism and allow the radial movements of the members 16, 22 relative to the axis 27 under the action of a movement ement of rotation communicated to said axis 27 by a handle 28.

La transformation du mouvement de rotation de l'axe 27 en mouvement de translation des organes de verrouillage 16, 22 selon une direction perpendiculaire à l'axe 27 est assurée par un disque 30 de configuration plane dont les faces sont respectivement tournées vers les organes de verrouillage 16, 22. Le disque 30 possède deux cavités arquées 31, 32 partiellement centrées sur l'axe de commande 27, dont chacune possède une partie excentrée 31e, 32e vers l'axe du disque et dans lesquelles sont engagés les axes de manoeuvre 23, 24 des organes de verrouillage 16, 22.The transformation of the rotational movement of the axis 27 into the translational movement of the locking members 16, 22 in a direction perpendicular to the axis 27 is ensured by a disc 30 of planar configuration, the faces of which are respectively turned towards the locking 16, 22. The disc 30 has two arcuate cavities 31, 32 partially centered on the control axis 27, each of which has an eccentric part 31e, 32e towards the axis of the disc and in which the operating axes 23 are engaged , 24 of the locking members 16, 22.

Selon un mode de réalisation préférentiel, les cavités arquées débouchent sur les deux faces du disque 30 et constituent deux lumières curvilignes. La disposition précitée autorise une réduction d'apaisseur appréciable au mécanisme. Une réduction complémentaire de l'épaisseur sera obtenue par montage du disque 30 à l'intérieur de l'anneau 19 et le montage de celui-ci dans la ferrure 11.According to a preferred embodiment, the arcuate cavities open on the two faces of the disc 30 and constitute two curvilinear openings. The aforementioned provision allows a significant reduction in thickness to the mechanism. A further reduction in thickness will be obtained by mounting the disc 30 inside the ring 19 and mounting it in the fitting 11.

A cet effet, la ferrure Il possède une chambre circulaire 35 dont la profondeur correspond sensiblement à l'épaisseur du verrou 22 et à la moitié de celle de l'anneau 19. La chambre 35 possède enfin un ou deux logements 36, 37 qui s'étendent radialement à la périphérie de celleci et qui sont destinés à recevoir le verrou 22 dans des positions différentes de verrouillage du dossier.To this end, the fitting II has a circular chamber 35 the depth of which corresponds substantially to the thickness of the latch 22 and to half that of the ring 19. The chamber 35 finally has one or two housings 36, 37 which s 'extend radially around the periphery thereof and which are intended to receive the latch 22 in different positions for locking the backrest.

Quand le dossier du siège présente par rapport à l'assise une certaine inclinaison représentée à la figure l, la partie dentée 17 de l'organe 16 possède vis à vis du secteur 13 une position définie, les dentures étant en prise et elles y sont maintenues par engagement de l'axe de manoeuvre 23 du verrou 16 dans la partie centrée de la lumière 31.When the seat back has a certain inclination with respect to the seat shown in FIG. 1, the toothed part 17 of the member 16 has, with respect to the sector 13, a defined position, the teeth being engaged and they are there maintained by engagement of the operating axis 23 of the latch 16 in the centered part of the slot 31.

L'axe 23 occupe de la sorte une position temporairement fixe. La position relative de la lumière 32 par rapport à la lumière 31 est telle que l'axe de manoeuvre 24 du verrou 22 se trouve dans la partie excentrée 32e de la lumière 32 tandis que l'axe de manoeuvre 23 demeure dans la partie centrée de la lumière 31 lorsque l'on décale angulairement d'un angle A le disque 30 au moyen de l'axe de commande 27 (fig 1).The axis 23 thus occupies a temporarily fixed position. The relative position of the light 32 relative to the light 31 is such that the operating axis 24 of the latch 22 is located in the eccentric part 32e of the light 32 while the operating axis 23 remains in the centered part of the light 31 when the disc 30 is angularly offset by an angle A by means of the control pin 27 (fig 1).

Le verrou 22 déplacé dans la coulisse 21 en direction de l'axe 27 quitte alors son logement 36, ou 37 sous l'effet de came de la partie 32e de la lumière 32 agissant sur l'axe 24.The bolt 22 moved in the slide 21 in the direction of the axis 27 then leaves its housing 36, or 37 under the cam effect of the part 32e of the light 32 acting on the axis 24.

La ferrure 11 est alors débrayée de l'anneau 19 portant la coulisse 21 et permet la modification rapide de la position du dossier d'un siège de passager avant, telle qu'elle est souhaitée pour favoriser l'accès aux places arrière d'un véhicule à une porte latérale. On peut autoriser le retour de l'axe de commande 27 dans sa position initiale par exemple lorsque celui-ci est rappelé dans cette position par un effort de rappel élastique ce qui peut être souhaité pour diminuer les contraintes passagères sur cet axe. A cet effet la ferrure 12 porte plusieurs logements 36, 37 du verrou 22 dont l'un peut être occupé par le verrou 22 dans la position représentée de la ferrure 11 à la figure 1.The fitting 11 is then disengaged from the ring 19 carrying the slide 21 and allows the rapid modification of the position of the back of a front passenger seat, as desired to facilitate access to the rear seats of a vehicle at a side door. We can authorize the return of the control shaft 27 to its initial position for example when the latter is returned to this position by an elastic return force which may be desired to reduce the transient stresses on this axis. To this end, the fitting 12 carries several housings 36, 37 of the latch 22, one of which can be occupied by the latch 22 in the position shown of the fitting 11 in FIG. 1.

Lorsque le dossier doit présenter par rapport à l'assise l'inclinaison correspondante à une position de confort telle que représentée à la figure 2, la partie dentée 17 de l'organe 16 devra posséder vis à vis du secteur 13 une position différente.When the backrest must have relative to the seat the inclination corresponding to a comfortable position as shown in Figure 2, the toothed portion 17 of the member 16 should have opposite sector 13 a different position.

Les'dentures doivent alors être maintenues hors prise pendant la recherche de la position de confort puis devoir entrer en prise lorsque ladite position a été trouvée. Les dentures sont d'abord libérées par engagement de l'axe de manoeuvre 23 du verrou 16 dans la partie excentrée 31e de la lumière 31 dont effet de came engendre un déplacement radial au verrou 16 vers l'axe de commande 27.The teeth must then be kept out of engagement during the search for the comfort position then must enter into engagement when said position has been found. The teeth are first released by engagement of the operating axis 23 of the latch 16 in the eccentric part 31e of the slot 31 whose cam effect generates a radial displacement of the latch 16 towards the control axis 27.

La position relative de la lumière 31 par rapport à la lumière 32 est telle que l'axe de manoeuvre 24 du verrou 22 reste dans la partie centrée de la lumière 32 si bien que ledit verrou 22 demeure dans le logement 36 de la ferrure 12. The relative position of the light 31 relative to the light 32 is such that the operating axis 24 of the latch 22 remains in the centered part of the light 32 so that said latch 22 remains in the housing 36 of the fitting 12.

Selon la figure 2 on a d'abord décalé d'un angle B le disque 30 au moyen de l'axe de commande 27. Il est à noter que le disque 30 a été décalé d'un angle B dans le sens contraire du précédent, référencé à la figure 1 correspondant à l'angle A. La position de confort étant trouvée, il est alors possible de ramener le disque 30 dans la position initiale dans le but de remettre en prise les dentures précitées.According to FIG. 2, the disc 30 has first been offset by an angle B by means of the control axis 27. It should be noted that the disc 30 has been offset by an angle B in the opposite direction to the previous one. , referenced in Figure 1 corresponding to angle A. The comfort position being found, it is then possible to return the disc 30 to the initial position in order to re-engage the abovementioned teeth.

De la description succinte du fonctionnement qui vient d'être faite mais qui est néanmoins suffisante pour la compréhension de l'invention, il apparaît que celle-ci peut être avantageusement appliquée sur différents types de sièges à dossiers inclinables dont chaque flanc porte le mécanisme conforme à l'invention. Les verrous 16 ou 22 sont alors maintenus en position au moyen d'un axe de commande commun muni par exemple de deux ressorts dont chacun prend appui d'une part sur l'axe de commande et d'autre part sur la ferrure i2.From the brief description of the operation which has just been made but which is nevertheless sufficient for the understanding of the invention, it appears that it can be advantageously applied to different types of seats with reclining backs, each side of which carries the conforming mechanism to the invention. The latches 16 or 22 are then held in position by means of a common control shaft provided for example with two springs, each of which bears on the one hand on the control shaft and on the other hand on the fitting i2.

Bien entendu le siège peut être équipé que d'un seul mécanisme,le c8té opposé à celui équipé comportera alors un axe simple.Of course, the seat can be equipped with only one mechanism, the side opposite to that equipped will then comprise a single axis.

Si l'on désire modifier le sens de commande de l'axe 27, il suffit d'orienter les lumières 31, 32 dans la position symétrique par rapport au plan I-I de la figure 3. Bien entendu l'invention n'est pas limitée à l'exemple de réalisation représentée, elle peut bien entendu recevoir diverses modifications sans sortir pour autant de son cadre. If it is desired to modify the direction of control of the axis 27, it suffices to orient the lights 31, 32 in the symmetrical position with respect to the plane II of FIG. 3. Of course the invention is not limited in the embodiment shown, it can of course receive various modifications without departing from its scope.
