Abstract

The convertible vehicle seat consists of a seat-cushion (10) which can fold down forwards and a back-rest cushion (30) which has a tilt axle (33) near the top to which are connected two levers (34, 35). The free ends (34a, 35a) of the levers are linked to bearings (6a, 6b) fixed to the vehicle's bodywork. A connection joining the cushion base to the bodywork consists of side slide pieces, one at least of which has locks for a pivoting bolt. A pivoting arm supports the axis for the cushion base (30) for the back-rest, and the pivot axle for the lock.

Description

Siège transformable, notamment de véhicule automobile.Convertible seat, especially for a motor vehicle.

L'invention concerne un siège transformable notamment de véhicule automobile qui possède un compartiment a bagages séparé de l'ha- bitacle par le dossier dudit siège qui comporte par ailleurs un coussin d'assise rabattable vers l'avant tandis que le coussin de dossier possède un axe de basculement a proximité de sa partie supérieure, auquel sont raccordés deux leviers dont ltextremite libre est articulée à des éléments de paliers solidaires du véhicule.The invention relates to a convertible seat, in particular for a motor vehicle, which has a luggage compartment separated from the passenger compartment by the back of said seat, which also comprises a seat cushion which can be folded forward while the back cushion has a tilting axis near its upper part, to which two levers are connected, the free end of which is articulated with bearing elements integral with the vehicle.

Les points de liaison de ces sièges au véhicule sont souvent inaccessibles et nécessitent des systèmes de manoeuvre à distance pour passer d'une position d'utilisation du siège à une autre position. Lorsque par exemple, l'organe de commande de déverrouillage du dossier est dissocié de ltorgane de commande du déverrouillage de l'assise, les changements de position du siège nécessitent l'exécution d'une suite de manipulations d'éléments du siège, difficilement réalisables par l'ensemble des personnes désirant obtenir une position d'utilisation différente du siège ou d'accroltre temporairement la capacite de chargement du compartiment à bagages.The connection points of these seats to the vehicle are often inaccessible and require remote operating systems to move from one position of use of the seat to another position. When, for example, the backrest unlocking control member is dissociated from the seat unlocking control member, the seat position changes require the execution of a series of manipulations of seat elements, which are difficult to carry out by all persons wishing to obtain a different position of use for the seat or to temporarily increase the loading capacity of the luggage compartment.

L'invention a pour objet de remédier aux problèmes posés par l'utilisation des sièges précités et concerne plus particulièrement un mécanisme de commande de tels sieges dont la plupart des changements de position peuvent être réalisés par un utilisateur.The object of the invention is to remedy the problems posed by the use of the aforementioned seats and relates more particularly to a control mechanism for such seats in which most of the position changes can be carried out by a user.

L'invention a également pour objet un mécanisme de commande de tels sièges qui permet d'obtenir à partir d'une position d'utilisation normale dans laquelle la base du coussin de dossier est solidaire de la partie postérieure du coussin de l'assise au choix.The invention also relates to a control mechanism for such seats which makes it possible to obtain, from a normal use position in which the base of the back cushion is secured to the rear part of the seat cushion at choice.

- une position dri coussin de dossier dont la partie supérieure
est avancée et lui donne une inclinaison plus réduite.
- a position on the back cushion, the upper part of which
is advanced and gives it a smaller tilt.

- une position du coussin de 1 assise également plus avancée qui
confère au dossier une inclinaison augmentee et un voiume de chargement accru au compartiment à bagages.
- a cushion position of 1 seat also more advanced which
gives the backrest an increased tilt and an increased loading capacity in the luggage compartment.

- une position en coussin de l'assise plus avancée tandis que la
partie supérieure du dossier occupe Ime position reculée dans
le but de conférer au dossier l'inclinaison conforme à une po
sition de relaxation.
- a more advanced cushioned seat position while the
upper part of the file occupies the retracted position in
the purpose of giving the backrest the inclination conforming to a po
relaxation session.

- une position de coussins de l'assise et de dossier rabattus vers
l'avant, dans le but de réaliser un plan de chargement du véhi
cule à l'emplacement du siège.
- a position of seat and back cushions folded towards
the front, in order to create a vehicle loading plan
cule at the location of the seat.

Selon l'invention un ensemble de liaison verrouillable de la base du coussin de dossier à la carrosserie est constitué par des glis sières latérales solidaires de la carrosserie dont l'une au moins porte des moyens de blocage d'un verrou pivotant de positionnement de la base du coussin de dossier, un bras portant l'axe d'articulation de la base du coussin de dossier et l'axe de pivotement du verrou, et un moyen d'actionnement du verrou et d'entrainement du dit bras entre des positions correspondant au recul et à l'avancement de la base du coussin de dossier.According to the invention, a lockable connection assembly from the base of the back cushion to the bodywork is constituted by lateral slides integral with the bodywork, at least one of which carries means for blocking a pivoting latch for positioning the base of the back cushion, an arm carrying the axis of articulation of the base of the back cushion and the pivot axis of the bolt, and a means for actuating the bolt and driving said arm between corresponding positions at the back and forward of the base of the back cushion.

Le siège ainsi réalisé peut se déplacer longitudinalement le long des glissières et être verrouillé dans celles-ci. I1 peut en outre être déverrouillé pour obtenir la séparation de la partie postérieure du coussin de l'assise, de la base du coussin de dossier, dans le but de faciliter l'agrandissement du compartiment à bagages. Le rabattement possible de l'assise vers l'avant et le basculement du dossier sur le plancher est alors rendu possible par suite de la séparation des extrémités libres des leviers raccordes à l'axe de basculement du dossier, de leurs paliers porteurs.The seat thus produced can move longitudinally along the slides and be locked therein. I1 can also be unlocked to obtain the separation of the rear part of the seat cushion from the base of the back cushion, in order to facilitate the enlargement of the luggage compartment. The possible folding of the seat towards the front and the tilting of the backrest on the floor is then made possible due to the separation of the free ends of the levers connected to the tilting axis of the backrest, from their bearing bearings.

Suivant une autre caractéristique avantageuse de l'invention, le moyen d'actionnement possède une fonction prioritaire destinée à la commande du verrou dans le sens du déverrouillage de dossier de Sa base du coussin par rapport à la glissière, et une fonction d'entralnement du bras pivotant portant l'axe d'articulation de la base du coussin de dossier. Dans ces conditions le sens de déplacement du moyen d'actionnement et le sens de déplacement du siège peuvent être identiques.According to another advantageous characteristic of the invention, the actuating means has a priority function intended for controlling the bolt in the direction of unlocking the back of its base of the cushion relative to the slide, and a function of centering the swivel arm carrying the articulation axis of the base of the back cushion. Under these conditions the direction of movement of the actuating means and the direction of movement of the seat can be identical.

D'autres caractéristiques et avantages de l'invention vont être mis en évidence dans la description qui va suivre faite en se référant au dessin annexé sur lequel - la figure 1 est une vue en élévation montrant le siège en position d'utilisation normale.Other characteristics and advantages of the invention will be highlighted in the following description made with reference to the accompanying drawing in which - Figure 1 is an elevational view showing the seat in the normal use position.

On a représenté partiellement à la figure 1 du dessin, un véhicule dont on apperçoit l'habitacle 1, le compartiment à bagages 2, une partie du plancher 3 attenant à la doublure du longeron lateral, le logement 4 de la porte arrière et une paroi latérale 5. Le plancher 3 et la paroi latérale 5 constituent des éléments de la carrosserie de ce véhicule.Partly shown in Figure 1 of the drawing, a vehicle which can be seen the passenger compartment 1, the luggage compartment 2, part of the floor 3 adjoining the lining of the side member, the housing 4 of the rear door and a wall side 5. The floor 3 and the side wall 5 constitute elements of the body of this vehicle.

Le siège transformable comprend un coussin d'assise 10, un coussin de dossier 30. Il est sous entendu que le terme "coussin" désigne l'ensemble des organes constitutifs de l'assise et du dossier et notamment leurs éléments d'ossature et de capitonnage.The convertible seat comprises a seat cushion 10, a back cushion 30. It is understood that the term "cushion" designates all of the constituent parts of the seat and of the backrest and in particular their frame elements and upholstery.

Dans la suite de la description on désignera par convention les organes liés au coussin de l'assise par les repères de 10 à 29 et les organes liés au coussin du dossier par les repères suivants 30, les repères de l à 10 étant réservés aux éléments fixes de la carrosserie.In the following description, the bodies linked to the seat cushion will be designated by convention by the marks from 10 to 29 and the bodies linked to the back cushion by the following marks 30, the marks from l to 10 being reserved for the elements. fixed to the body.

La partie antérieure du coussin de l'assise porte une traverse 22 formant axe liée a' l'ossature du coussin, sur lequel sont articulées deux biellettes 24, 25 réunies par leurs extrémités libres à des chapes
rapportées sur le plancher 3 du véhicule. La partie postérieure (fig 9) du coussin d'assise 10 porte également un élément d'ossature constitué- par une traverse 14. Un support 15 fixé à la traverse 14 dans la zone médiane de celle-ci, s'étend vers la base du coussin de dossier 3û. Le support 15 qui est forme dans un élément de tôle découpée et pliée possède plusieurs parties fonctionnelles que sont un pied de fixation 1 solidaire de la traverse 14, un palier de retenue 17 d'un axe 18 fixé à un verrou pivotant 19 à ressort de rappel. !'xtrénité du support 15 est conformée en une fourchette de retenue ^wf Ce la traverse inferieure 31 du coussin de dossier 30.
The front part of the seat cushion carries a crosspiece 22 forming an axis linked to the framework of the cushion, on which are articulated two links 24, 25 joined by their free ends to yokes
reported on floor 3 of the vehicle. The rear part (fig 9) of the seat cushion 10 also carries a framework element constituted by a cross member 14. A support 15 fixed to the cross member 14 in the central region thereof, extends towards the base of the back cushion 3û. The support 15 which is formed in a cut and folded sheet metal element has several functional parts such as a fixing foot 1 secured to the crosspiece 14, a retaining bearing 17 of an axis 18 fixed to a pivoting latch 19 with a spring of reminder. ! xtrénité of the support 15 is shaped into a retaining fork ^ wf This the lower cross member 31 of the back cushion 30.

ct effet la traverse infrieure 31 possède un amincissement local 32 de diamètre ~arrespondant l'écartement de la fourchette de retenue 20, tandis que le verrou à ressort 19 se termine par un crochet de retenue 19a qui vient coiffer la portion 32 de la traverse et assure la rétention de celle-ci entre les dents de la fourchette 20. L'extrémité libre du verrou 19 porte une tirette de manoeuvre 21 accessible au manipulateur du siège. ct effect the lower cross member 31 has a local thinning 32 of diameter ~ corresponding to the spacing of the retaining fork 20, while the spring latch 19 ends with a retaining hook 19a which covers the portion 32 of the cross member and ensures the retention of the latter between the teeth of the fork 20. The free end of the latch 19 carries an operating puller 21 accessible to the manipulator of the seat.

La manoeuvre de la tirette 21 s'opère lors du rabattement du coussin de l'assise vers l'avant. A cet effet la partie antérieure de ce coussin porte une traverse 22 portant les palliers de deux biellettes d'articulation 24, 25 dont les extrémités sont respectivement articulées sur des paliers correspondants solidaires du plancher 3 (fig 2).The pulling rod 21 is operated when the seat cushion is folded forward. To this end, the front part of this cushion carries a crosspiece 22 carrying the bearings of two articulation links 24, 25 the ends of which are respectively articulated on corresponding bearings secured to the floor 3 (FIG. 2).

Le coussin de dossier 30 possède à proximité de sa partie supérieure un axe de basculement 33 auquel sont raccordés-deux leviers 34, 35 dont l'extrémité libre 34a, 35a est articulée à des éléments de palier 6a, 6b solidaires des parois latérales 5. Les éléments de paliers 6a, 6b possèdent par ailleurs une rainure de guidage 7 qui s'étend- longitudinalement entre deux logements 7a, 7b de l'ex- trémité correspondante des leviers 34, 35. La rainure de guidage 7 débouche au contact d'une rampe de montage et de fixation 8. Le blocage des leviers 34, 35 le long de la rainure 7 ou dans les logements 7a, 7b est assuré par un écrou 9 ainsi que cela est bien connu (fig i,
L'ensemble de liaison destiné au verrouillage de la base du coussin de dossier à la carrosserie est le mieux représenté aux figures 7 et 9.Cet ensemble est désigné par le repère 40 dans son ensemble.
The back cushion 30 has, near its upper part, a tilting axis 33 to which two levers 34, 35 are connected, the free end 34a, 35a of which is hinged to bearing elements 6a, 6b integral with the side walls 5. The bearing elements 6a, 6b also have a guide groove 7 which extends longitudinally between two housings 7a, 7b of the corresponding end of the levers 34, 35. The guide groove 7 opens in contact with a mounting and fixing ramp 8. The blocking of the levers 34, 35 along the groove 7 or in the housings 7a, 7b is ensured by a nut 9 as is well known (fig i,
The connection assembly intended for locking the base of the back cushion to the bodywork is best represented in FIGS. 7 and 9. This assembly is designated by the reference 40 as a whole.

I1 est en fait constitué par deux ensembles disposés de part et d'autre du coussin de l'assise du siège. I1 is in fact constituted by two assemblies arranged on either side of the seat cushion.

Chaque ensemble représenté sur les figures 7 et 9 est composé d'une glissière latérale 41 constituée par une flasque de tôle pliée et découpée. La flasque possède de la sorte des pieds de fixation 42, 43 au plancher 3 et une lumière arquée 44 dont les extrémites portent des logements de blocage 45, 46 d'un verrou à ressort 47 qui positionne la base du coussin de dossier 30. La lumière arquée 44 est centrée sur un axe 48 sur lequel est monté à rotation un bras pivotant 49. Le bras pivotant 49 pcrte un premier axe 50,d'articulation de la base du coussin de dossier 30 matérialisé par les deux montants latéraux 52 entretoisés par la traverse inférieure 31 et un deuxième axe 51 de pivotement du verrou 47. Il se prolonge radialement entre les parties fonctionnelles du moyen d'actionnement par une palette 49a.Le verrou 47 possède des moyens de commande de pivotement constitués par un premier doigt 53 et par un deuxième doigt 54. Les doigts 53 et 54 sont respectivement en appui avec des parties fonctionnelles d'un moyen d'actionnement constitué par un levier 55 monté à rotation autour de l'axe de rotation 48 du bras 49. Les parties fonctionnelles précitées sont constituées par - une fourchette de commande 56 dont les dents 56a, 56b assurent l'entraînement du premier doigt 53 du verrou 47 ou de la palette 49a du bras 49.Each assembly shown in Figures 7 and 9 is composed of a lateral slide 41 constituted by a flange of folded and cut sheet metal. The flange thus has feet 42, 43 for fixing to the floor 3 and an arcuate opening 44, the ends of which carry blocking housings 45, 46 of a spring latch 47 which positions the base of the back cushion 30. The arcuate light 44 is centered on an axis 48 on which is pivotally mounted a pivoting arm 49. The pivoting arm 49 pcrte a first axis 50, of articulation of the base of the back cushion 30 materialized by the two lateral uprights 52 braced by the lower cross member 31 and a second pivot axis 51 for pivoting the latch 47. It extends radially between the functional parts of the actuation means by a pallet 49a. The latch 47 has pivoting control means constituted by a first finger 53 and by a second finger 54. The fingers 53 and 54 are respectively in abutment with functional parts of an actuating means constituted by a lever 55 mounted for rotation about the axis of rotation 48 of the arm 49. The parts f above mentioned functions consist of - a control fork 56 whose teeth 56a, 56b drive the first finger 53 of the latch 47 or the pallet 49a of the arm 49.

- une surface de came 57 qui assure l'entraînement du deuxième doigt 54 du verrou. Ainsi que cela a été représenté à la figure 9, le premier doigt 53 du verrou 47 est tourné vers la palette de poussée et d'entrainement 49a.- A cam surface 57 which drives the second finger 54 of the lock. As shown in FIG. 9, the first finger 53 of the latch 47 is turned towards the thrust and drive pallet 49a.

Le fonctionnement du siège est le suivant
Le coussin de dossier 30 est ajustable longitudinalement selon la position des extrémités 34a, 35a des leviers 34, 35 dans la rainure 7, notamment lorsque le coussin de l'assise 10 est verrouillé avec la traverse inférieure 31 du coussin de dossier ainsi que cela est représente à la figure 10.
The operation of the headquarters is as follows
The back cushion 30 is adjustable longitudinally according to the position of the ends 34a, 35a of the levers 34, 35 in the groove 7, in particular when the seat cushion 10 is locked with the lower cross member 31 of the back cushion as is shown in Figure 10.

Pour transfonner la position du siège représentée à la figure 1 et obtenir la position représentée à la figure 3, il suffit de deplacer les extrémités 34a, 35a des leviers 34, 35, du logement 7b au logement 7ade la rainure 7. To transfer the position of the seat shown in FIG. 1 and obtain the position shown in FIG. 3, it suffices to move the ends 34a, 35a of the levers 34, 35, from the housing 7b to the housing 7ade the groove 7.

Pour obtenir la position du siège représentée à la figure 4 il suffit de manoeuvrer le levier 55 dans le sens recherche à l'avancement du siège représenté par la flèche A. Au cours de ce déplacement la dent 56a de la fourchette 56 entraine en rotation le premier doigt 53 du verrou 47. Le déplacement correspondant du verrou 47 assure le retrait de celui-ci du logement de blocage 46 dahs la glissière 41. Le doigt 53 conformé en une palette vient en appui sur la palette correspondante 49a du bras 49.To obtain the position of the seat shown in FIG. 4, it suffices to operate the lever 55 in the direction of search for the advancement of the seat represented by the arrow A. During this movement the tooth 56a of the fork 56 rotates the first finger 53 of the latch 47. The corresponding movement of the latch 47 ensures the withdrawal of the latter from the blocking housing 46 in the slide 41. The finger 53 shaped as a pallet bears on the corresponding pallet 49a of the arm 49.

Le bras 49 est de ce fait déverrouillé et est entraîné en rotation par la fourchette 56 autour de l'axe 48. Dans la position finale du bras 49 représentée à la figure 8, le verrou 47 s'engage sous l'action de son ressort dans le logement de blocage 45 de la glis sière 41. Le coussin de dossier est alors de nouveau verrouillé.The arm 49 is therefore unlocked and is rotated by the fork 56 around the axis 48. In the final position of the arm 49 shown in Figure 8, the latch 47 engages under the action of its spring in the blocking housing 45 of the slide rail 41. The back cushion is then again locked.

Pour obtenir la position du siège représentée à la figure 5, à partir de celle représentée à la figure 4, il suffit de déplacer les extrémités 34a, 35a des leviers 34,35 du logement 7b au logement 7a.To obtain the position of the seat shown in Figure 5, from that shown in Figure 4, simply move the ends 34a, 35a of the levers 34,35 from the housing 7b to the housing 7a.

Pour obtenir la position du siège représentée à la figure 1, à partir de celle représentée à la figure 5 il suffit de manoeuvrer le levier 55 dans le sens recherché au recul du siège representé par la flèche R. Au cours de ce déplacement, la surface de came 57 assure l'entraînement du deuxième doigt 54 du verrou 47. Le déplacement correspondant du verrou 47 autour de son axe 51 assure le retrait de ce verrou du logement de blocage 45 dans la glissière 41.To obtain the position of the seat shown in FIG. 1, from that shown in FIG. 5, it suffices to operate the lever 55 in the desired direction when the seat represented by the arrow R moves backward. During this movement, the surface cam 57 drives the second finger 54 of the latch 47. The corresponding movement of the latch 47 about its axis 51 ensures the removal of this latch from the blocking housing 45 in the slide 41.

La dent 56b de la fourchette 56 vient en appui sur la palette 49a du bras 49 qui est alors entrainé en rotation par la fourchette 56 autour de l'axe 48.The tooth 56b of the fork 56 comes to bear on the pallet 49a of the arm 49 which is then rotated by the fork 56 around the axis 48.

Dans la position finale du bras 49 représentée à la figure 7, le verrou 47 s'engage sous l'action de son ressort dans le logement de blocage 46 de la glissière 41. Le coussin de dossier est alors de nouveau verrouillé.In the final position of the arm 49 shown in Figure 7, the latch 47 engages under the action of its spring in the blocking housing 46 of the slide 41. The back cushion is then again locked.

Pour obtenir la position du siège représentée à la figure 6 on part de préférence de la position représentée à la figure 1. On manoeuvre alors la tirette 21 dans le but de déverrouiller le coussin de l'assise et on le rabat vers l'avant autour de l'axe transversal 22. Après avoir dévissé les écrous de blocage 9 des leviers 34, 35 et sépare ceux-ci de la rainure 7 des paliers 6a, 6b, le coussin de dossier peut être basculé contre le plancher 3 autour de l'axe d'articulation 50.To obtain the position of the seat shown in FIG. 6, it is preferable to start from the position shown in FIG. 1. The puller 21 is then operated in order to unlock the seat cushion and it is folded forward around of the transverse axis 22. After having unscrewed the locking nuts 9 of the levers 34, 35 and separates these from the groove 7 of the bearings 6a, 6b, the back cushion can be tilted against the floor 3 around the hinge pin 50.

Du mode de fonctionnement précité il apparait clairement que la liaison du coussin de l'assise avec la traverse 31 du coussin de dossier, autorise l'avancement ou le recul du coussin de l'assise, sous l'action des déplacements communiqués au levier 55. From the aforementioned operating mode, it clearly appears that the connection of the seat cushion with the cross member 31 of the back cushion, allows the seat cushion to move forward or backward, under the action of the movements communicated to the lever 55 .
