Abstract

The device has a locking slide and parallelepiped metallic body provided in a lower part of a leg of a removable seat. The slide occupies a longitudinal adjustment position, in which the slide rises towards an inner space of the leg and ensures the displacement of a sliding block (B), and a locking position in which the slide emerges from the leg and cooperates with holes (4) carried by upper lips (3) of a rail (A). A guiding unit is constituted of a guide opening and vertical finger and permits the displacement of the slide between the two positions.

Description

- La presente invention se rapporte a un dispositif de reglageThe present invention relates to a control device

longitudinal , son systeme de verrouillage ainsi qu'aux sieges de vehicule comportant d'un tel dispositif. L'invention concerne notamment les glissieres pour sieges de vehicules utilitaires, celles qui comprennent : Un rail fixe destine a titre fixe sur le plancher du vehicule,une partie mobile coulissante dans le rail selon une direction longitudinale entre une position arriere extreme et une position avant extreme. La partie mobile est destinee a supporter le siege du vehicule. Le mecanisme de verrouillage est adapte pour titre soit dans une position verrouillee dans laquelle ce mecanisme bloque le deplacement de la partie mobile par rapport au rail fixe, soit dans une position deverrouillee dans laquelle ce mecanisme permet le deplacement de la partie mobile par rapport au rail fixe.  longitudinal, its locking system and the vehicle seats comprising such a device. The invention relates in particular to the slides for commercial vehicle seats, those comprising: A fixed rail intended for fixed purposes on the floor of the vehicle, a movable portion sliding in the rail in a longitudinal direction between an extreme rear position and a forward position extreme. The moving part is intended to support the seat of the vehicle. The locking mechanism is suitably adapted either in a locked position in which this mechanism blocks the displacement of the movable part relative to the fixed rail, or in an unlocked position in which this mechanism allows the displacement of the movable part relative to the rail fixed.

Ce dispositif de reglage longitudinal est destine a supporter une assise de siege dont la position longitudinale doit pouvoir titre *lee A la convenance d'un utilisateur .Ce dispositif doit egalement pouvoir titre deplace vers les deux positions extremes pour permettre ,si necessaire,l'enlevement du siege et le blocage des parties mobiles du dispositif.  This longitudinal adjustment device is intended to support a seat base whose longitudinal position must be entitled * lee at the convenience of a user .This device must also be able to move to the two extreme positions to allow, if necessary, the removing the seat and blocking the moving parts of the device.

Le document 25 DEA-19 924 579 decrit notamment un tel dispositif. Y est explique le fonctionnement d'un systeme du genre precite qui comprends un coulisseau sur lequel vient se positionner un siege. A ce coulisseau est associe un curseur de verrouillage qui est fixe, grace a un axe transversal, a ce dernier. Le curseur peut venir selectivement s'engager dans des echancrures prevues dans les ailes en regard dudit rail, par un mouvement en arc de cercle centre sur cet axe. Ceci a pour effet ,dans cette derniere position, de bloque le coulisseau et d'immobiliser le siege. Lorsque le curseur est pousse vers I'interieur du rail afin qu'il ne coopere plus avec les echancrures,ceci permet de deplacer comme on le souhaite le coulisseau et le siege associe. Le fait que le curseur subisse un mouvement en arc de cercle fait que ce dernier risque de se bloquer lorsqu'on souhaite qu'il coopere avec 5 les echancrures. Le coulisseau a donc une longueur relativement importante, de maniere a ce que le bras de levier du curseur soft egalement important et que toutes les tentatives de cooperation avec les echancrures reussissent.  Document DEA-19 924 579 notably describes such a device. It explains the operation of a system of the kind mentioned above which includes a slide on which is positioned a seat. This slider is associated with a locking slider which is fixed, thanks to a transverse axis, to the latter. The slider can selectively engage in notches provided in the flanges facing said rail, by a movement in the form of an arc centered on this axis. This has the effect, in the latter position, blocks the slide and immobilize the seat. When the cursor is pushed towards the inside of the rail so that it no longer co-operates with the notches, this makes it possible to move the slide and the associated seat as desired. The fact that the cursor is moving in an arc causes the cursor to lock when it wishes to cooperate with the notches. The slide is therefore relatively long, so that the lever arm of the soft slider is equally important and all attempts to cooperate with the notches succeed.

La presente invention a pour but de pallier a cet inconvenient en proposant un dispositif du meme genre qui soit plus compact avec une structure simplifiee.  The present invention aims to overcome this disadvantage by proposing a device of the same kind that is more compact with a simplified structure.

II s'agit d'un dispositif de reglage longitudinal et de blocage en position predeterminee d'un siege pour vehicule utilitaire , par rapport a deux rails paralleles a section en C a levres superieures percees de trous , et a ouverture dirigee vers le haut. Ces rails equipent le plancher horizontal du vehicule. Un coulisseau supportant le siege du vehicule coulisse dans chaque rail .Ce coulisseau possede un systeme de blocage en met en action tors de I'enlevement du siege en extremite de rail.  It is a device for longitudinal adjustment and locking in predetermined position of a seat for commercial vehicle, with respect to two parallel rails with a C section with upper holes pierced, and an opening directed upwards. These rails equip the horizontal floor of the vehicle. A slider supporting the seat of the vehicle slides in each rail .This slider has a locking system actuates torsion of the removal of the seat at the end of the rail.

Ce dispositif se caracterise essentiellement par le fait que dans la partie inferieure du pietement du siege est prevue une reservation dans laquelle sont engages les moyens de guidage du curseur de blocage du coulisseau ainsi que ceux du verrou de blocage du pietement du siege. Ces moyens autorisent leur deplacement selon un mouvement de translation verticale. Le curseur de verrouillage du coulisseau est adapte pour occuper deux positions extremes, a savoir : une premiere position de reglage longitudinal dans laquelle fl remonte vers I'espace inferieure du pietement du siege et autorise le deplacement du coulisseau , une seconde position ,dite de blocage, dans laquelle fl coopere parfaitement avec les levres superieures crantees du rail. Ces moyens de guidages consiste pour le curseur de blocage du coulisseau a une piece metallique parallelepipedique , Percee de part en part ,et verticalement ,en son milieu .en sa partie haute le trou de per-gage est legerement en retrait par rapport a sa partie basse .fl permet cependant le passage du doigt vertical du curseur de blocage. ce retrait est comble par I epaisseur d'un ressort de pression qui est emmanche sur !edit doigt qui bloque le ressort en sa partie basse par un epaulement .le curseur de blocage est ainsi maintenu en permanence en blocage. La face inferieure du curseur comporte dans les regions situees a ('aplomb des levres superieures perckes de trous du rail ,au moms un teton metallique apte a venir s'engager dans un moms un trou prevues dans lesdites levres superieures. pour assurer ladite position de blocage. Ladite face inferieure du curseur presente une zone axiale et longitudinale formant surepaisseur, dont le dessous presente une rangee longitudinale de tetons metallique,tandis que le bord des levres superieures comporte des trous de forme complementaire Le dit equipement est pourvu de moyen d'actionnement tel qu'un levier actionnant une tige transversale apte a venir soulever par une translation verticale le doigt du curseur de blocage.  This device is essentially characterized by the fact that in the lower part of the base of the seat is provided a reservation in which are engages the guide means of the slider locking slider as well as those of the locking lock of the seat pedestrian. These means allow their displacement in a vertical translational movement. The slider locking slider is adapted to occupy two extreme positions, namely: a first longitudinal adjustment position in which fl goes back to the lower space of the seat and allows the movement of the slider, a second position, called blocking , in which fl cooperates perfectly with the upper lips notches of the rail. These guide means consists for the blocking slider of the slider to a parallelepipedic metal piece, Percee from side to side, and vertically, in its middle. In its upper part the piercing hole is slightly recessed with respect to its part low .fl however allows the passage of the vertical finger of the blocking slider. this withdrawal is filled by the thickness of a pressure spring which is fitted on the finger which blocks the spring at its lower part by a shoulder. The blocking slider is thus kept permanently locked. The lower face of the slider comprises, in the regions situated above the upper lips pierced with holes in the rail, at least one metallic teton able to engage in at least one hole provided in said upper lips. The lower face of the slider has an axial and longitudinal region forming a thickness, the underside of which has a longitudinal row of metal studs, while the edge of the upper lips has holes of complementary shape The said equipment is provided with actuating means. such as a lever actuating a transverse rod adapted to lift by vertical translation the finger of the locking slider.

Le verrou de blocage du pietement du siege est adapte pour occuper deux positions extremes , a savoir : une premiere position dans laquelle fl remonte vers I'espace inferieure du pietement du siege et autorise par un mouvement translatif horizontal arriere ,par rapport au devant du vehicule, la desolidarisation des crochets situes sous les extremites avant et arriere du pietement du coulisseau. une seconde  The locking latch of the seat carriage is adapted to occupy two extreme positions, namely: a first position in which fl goes back to the lower space of the seat base and authorizes by a rear horizontal translational movement, relative to the front of the vehicle , the separation of the hooks located under the front and rear ends of the base of the slider. a second

Ce rail metallique (A) a une section en C Avec un fond (1), deux cotes verticaux et paralleles (2) ainsi que deux levres horizontales superieures (3) Qui se font face. Ces levres superieures sont percees par des trous(4) qui suivent longitudinalement ('ouverture centrale du rail en C. Elles sont separees par une ouverture longitudinale permettant I' accts a ('interieur du rail. Le fond du rail possede en ses deux extremites, et sur toute sa largeur,de deux decoupes identiques (D) faites en retrait. Le fond du rail est donc plus petit que les deux cotes verticaux (2) et que les deux levres superieures (3).  Rail (A): Profile intended for fixed purposes on the horizontal floor of the vehicle. This metal rail (A) has a section C with a bottom (1), two vertical and parallel dimensions (2) and two upper horizontal lips (3) facing each other. These upper lips are pierced by holes (4) which follow longitudinally (central opening of the rail C. They are separated by a longitudinal opening allowing access to the inside of the rail.The bottom of the rail has in its two ends , and over its entire width, two identical cuts (D) set back, the bottom of the rail is smaller than the two vertical dimensions (2) and the two upper lips (3).

Coulisseau (B):Dans le rail (A) est loge un coulisseau (B) qui supporte le siege. Ce coulisseau (B) s'inscrit clans I'espace interieur du rail et se compose de plusieurs elements: Une partie centrale (5) constitute par une platine parallelepipedique dont la surface superieure est alignee sur la partie inferieure (6) de I'epaisseur des levres horizontales (3) du rail .Cette partie centrale (5) est percee en son milieu, a ('axe, par un trou circulaire (7) ,Elle est fixee sous deux autres platines parallelepipedique d'extremite (8), de meme largeur. Ces platines d'extremite s'inscrivent parfaitement, en forme et dimensions, entre les levres horizontales superieures du rail (3) et servent de guidage au Coulisseau. Une ouverture parallelepipedique (9) y est faite, a ('axe, afin de creer un rebord d'accrochage (10)lors de leur fixations sur le dessus des chariots (11) d extremite avec la reserve faite dans ces derniers et destinee au logement du Iinguet(12).Ces chariots se composent d'une forme Parallelepipedique avec des reservations cubiques (13) faites sur la longueur permettant le logement des galets de roulement (14).Ces galets de roulement s'inscrivent parfaitement entre le fond (1) et les levres superieures horizontales (3) du rail. Ces galets de roulement sont fixes deux par deux par un axe (15) qui traverse transversalement chaque chariot (11).ces derniers possedent une extrtmitt ,tournee vers I'exterieure du coulisseau,qui se termine par deux branches longitudinales (16) separees par un intervalle (17) donnant une forme generale d'etrier. Cette forme generale d' etrier permet ('insertion d'un linguet(12) piece metallique plate en forme generale de L sortant pour partie, du chariot. La partie exterieure se termine par un rebord (19) tournee vers le fond du rail (1).Ce linguet (12) est traversee dans sa partie inserte dans le chariot par un des axes(15) qui sert aussi a fixer deux galets de roulements. Un ressort (20) fixe en son extremite superieure sur le dessous de la platine d'extremite (8), permet de maintenir en permanence une pression vers le bas sur la partie exterieure de du linguet(12). Pietement (c) :En ce rapportant a la vue de cote de la figure Ion constate que la partie inferieure du siege positionne sur le coulisseau, comporte une partie centrale evidee sous la forme dune traverse en U inverse (21) Cet espace permet le logement du systeme de blocage (22) du coulisseau. Ce systeme se compose, en partie haute, d'un corps metallique parallelepipedique (23), en partie basse, d'un curseur de blocage (24) avec,en son milieu un doigt vertical (25),dirige vers le haut,. La hauteur de ce doigt vertical (25)depasse legerement le niveau de ('ouverture (26) faite pour permettre son passage a travers le haut de la traverse en U inverse (21).Ceci permet le passage transversal d'une goupille de blocage (27) dans la partie emergente du doigt vertical. Ce curseur de blocage(24) possede une forme axiale et longitudinale qui forme une surepaisseur. La partie inferieure (i) de cette surepaisseur possedent longitudinalement des tetons metalliques((28) de meme forme que les trous (4) perces dans les levres superieures (3) du rail. La repartition des tetons metalliques (28) est telle, gulls sont prevus pour venir se placer dans les trous (4) des levres superieures (3) du rail selon la course representee par la double fleche de mouvement H Ce curseur de blocage (24) a sa course verticale stoppee vers le bas par la partie superieure de la surepaisseur servant de fond aux tetons et s'appuyant ,par pression, sur le dessus des levres horizontales (3) superieures. Ce curseur de blocage (24) est egalement Iimitee vers le haut par une ouverture de guidage (29) faite dans le corps metallique parallelepipedique (23) insert dans le pietement .Cette ouverture de guidage permet le passage horizontal , de I'exterieur vers ('interieur ,d'une tige metallique (30) fixee au doigt vertical (25) .cette derniere est reliee a un systeme de levage tel un palonnier. Ce corps metallique parallelepipedique (23)a des dimensions exterieures qui s'inserent parfaitement a ('interieur de la traverse en U inverse (21).11 est traverse depuis sa face inferieure vers sa face superieure par une ouverture(29) qui se prolonge en partie haute, par un canal (30) de meme forme ,plus etroit et formant un rebord. Ces pergages sont destinees a permettre I' engagement du doigt vertical (25).Les dimensions du canal (30) sont legerement superieures a celles du doigt vertical. L'ouverture (29) Est cependant prevue pour recevoir un ressort de compression (31) qui est emmanche sur la partie superieure ( 32)du doigt vertical .ce ressort prends appuie, en partie haute sur fond du canal (30) et en partie basse sur I'epaulement (31)de la partie inferieure situee dans I' ouverture (29) dudit doigt. Ce ressort applique une pression vers le bas au curseur de blocage (24) via le doigt Vertical (25). Ce doigt vertical est traverse perpendiculairement par une tige horizontale (30) quidee verticalement par deux reserves verticales faites en correspondance dans le corps metallique et permettant son coulissement. Cette tige est relit a un systeme d'actionnement comme un palonnier permettant par son action vers le haut de Transmettant le mouvement vertical H au doigt vertical (25) Du Curseur de blocage (24) La figure 2 represente une premiere position extreme du curseur de blocage (24) dans laquelle it est completement releve par rapport aux deux levres superieures (3) du rail .Dans ces conditions le coulisseau (B)peu librement titre deplace selon ('axe longitudinal X du rail. La figure 1 represente une deuxieme position extreme du curseur de blocage (24) dans laquelle au moins un tetons metaltiques (28) de sa partie inferieure collabore avec au moins un trou (4) perces dans les levres horizontales (3) superieures. Dans ces conditions le coulisseau ... est immobilise en direction longitudinale.  Slider (B): In the rail (A) is a slider (B) which supports the seat. This slider (B) is inscribed in the interior space of the rail and is composed of several elements: A central part (5) constituted by a parallelepipedal plate whose upper surface is aligned on the lower part (6) of the thickness horizontal lips (3) of the rail .This central part (5) is pierced in the middle, on the axis, by a circular hole (7), It is fixed under two other parallelepipedic end plates (8), The end plates fit perfectly, in shape and dimensions, between the upper horizontal lips of the rail (3) and serve as a guide for the slider.A parallelepipedal opening (9) is made on the in order to create a hooking flange (10) when they are fastened to the top of the carriages (11) end with the reserve made in them and intended for housing Iinguet (12). These carriages consist of a shape Parallelepipedique with cubic reservations (13) made on the length allowing the housing of the rollers (14) .These rollers fit perfectly between the bottom (1) and the upper horizontal lips (3) of the rail. These rollers are fixed two by two by an axis (15) which transversely traverses each carriage (11) .The latter have an end, turned towards the outside of the slide, which ends with two longitudinal branches (16) separated by an interval (17) giving a general shape of etrier. This general form of caliper allows insertion of a pawl (12) flat metal part in the general form of L partially out of the carriage.The outer part ends with a rim (19) turned towards the bottom of the rail ( 1) .This pawl (12) is traversed in its inserted part in the carriage by one of the pins (15) which also serves to fix two rollers bearings.A spring (20) fixed at its upper end on the underside of the plate end (8), allows to maintain permanently a downward pressure on the outer part of the pawl (12) .Position (c): In relation to the side view of the figure Ion finds that the lower part of the seat positioned on the slide, comprises a central part evidee in the form of a transverse U-shaped crossbar (21) This space allows the housing of the locking system (22) of the slider.This system consists, in the upper part, of a parallelepipedic metal body (23), in the lower part, of a locking slider (24) with, in its middle a vertical finger (25), directs up ,. The height of this vertical finger (25) slightly exceeds the level of ('opening (26) made to allow its passage through the top of the U-shaped cross member (21) .This allows the transverse passage of a locking pin (27) in the emergent portion of the vertical finger.This locking slider (24) has an axial and longitudinal shape which forms a thickness.The lower part (i) of this extra thickness have longitudinally metal nipples ((28) of the same shape. the holes (4) are pierced in the upper lips (3) of the rail.The distribution of the metal nipples (28) is such that they are intended to be placed in the holes (4) of the upper lips (3) of the rail according to the race represented by the double movement arrow H This locking slider (24) has its vertical stroke stopped downwards by the upper part of the over-thickness serving as a bottom for the teats and pressing, by pressure, on the top of the lips horizontal (3) superiors. The blocking lock (24) is also limited upwards by a guide opening (29) made in the parallelepipedal metal body (23) inserted into the base. This guide opening allows the horizontal passage from the outside to the outside. interior, a metal rod (30) fixed to the vertical finger (25) .This latter is connected to a lifting system such as a rudder. This parallelepipedal metal body (23) has external dimensions which fit perfectly inside the U-shaped cross member (21). It is traversed from its lower face towards its upper face by an opening (29) which extends in the upper part, by a channel (30) of the same shape, more narrow and forming a flange.These pergages are intended to allow the engagement of the vertical finger (25) .The dimensions of the channel (30) are slightly greater than those of the The opening (29) is however intended to receive a compression spring (31) which is fitted on the upper part (32) of the vertical finger .ce this spring takes support, in the upper part on the bottom of the channel (30) and in the lower part on the shoulder (31) of the lower part situated in the opening (29) of said finger.This spring applies a downward pressure to the locking slider (24) via the vertical finger (25). vertical finger is traversed perpendicularly by a horizontal rod (30) q uidee vertically by two vertical reserves made in correspondence in the metal body and allowing its sliding. This rod is read to an actuating system such as a rudder allowing its upward action by transmitting the vertical movement H to the vertical finger (25) of the blocking slider (24). Figure 2 represents a first extreme position of the slider. blocking (24) in which it is completely raised with respect to the two upper lips (3) of the rail. In these conditions the slider (B) is loosely displaced by the longitudinal axis X of the rail. end of the locking slider (24) in which at least one metal studs (28) of its lower part collaborates with at least one hole (4) perces in the horizontal lips (3) superieures. In these conditions the slider ... is immobilizes in the longitudinal direction.

Dans la figure 1 on constate que la traverse en U inverse (21) est entouree par deux montants verticaux (33) dont la partie inferieure se prolonge vers le bas par deux butte en forme de F >> inverse (34) avec une encoche horizontale (35).Ces buttes font le lien entre le siege et le coulisseau (B) et supportent le poids du siege. Elles s'inserent verticalement selon la double fleche H s dans les ouvertures parallelepipediques (9) du coulisseau et s'y solidarisent, par une translation horizontale vers I'avant du vehicule,avec le rebord (10) De ('ouverture parallelepipedique (9). Un verrou compose par un doigt d'indexage (33) dispose dans la traverse en U inverse (21) et en 'arriere du systeme de blocage (22). Permet le maintien definitif du siege sur le coulisseau en evitant tout retrait. Ce verrou se compose notamment d'un doigt vertical qui vient se loger verticalement et selon une translation verticale H N de haut en bas, en sa position de blocage, dans le trou (7)de la partie centrale (5) du coulisseau (B). Ce verrou est sollicite par un utilisateur fors de la pose ou la depose du siege sur les coulisseaux. Une translation verticale H s de bas vers le haut du verrou releve le doigt d'indexage (33) et libere ainsi le trou(7) de la platine centrale(5) permettant de retirer le siege du coulisseau par une translation horizontale vers I'arriere du vehicule. Ces deux operations peuvent se faire en partie d' extremite des rails. Les buttes en forme de a F inverse (34) appuient sur la partie arriere superieure des linguets (12) tors de la fixation du siege sur les coulisseaux. Cette action a pour effet de remonter le rebord (19) d'extremite vers le haut selon une rotation sur I' axe (15) des galets (14) et les desolidarise des decoupe (D) faite dans le fond des rails. Le coulisseau peut alors circuler dans le rail. L'operation inverse s'effectue tors de la depose du siege des coulisseaux. Les buttes en forme de F inverse etant parties, Ies ressorts (20) appliquent leur pression sur la partie superieure avant du linguet (12) lui impliquant une rotation vers le bas sur ('axe (15) des galets.Le rebord (19) du linguet (12) collabore alors avec la decoupe c D du fond du rail. Les coulisseaux sont bloques. S  In FIG. 1 it can be seen that the U-shaped cross member (21) is surrounded by two vertical uprights (33), the lower part of which is extended downwards by two F >> -shaped counters (34) with a horizontal notch (35). These mounds make the link between the seat and the slider (B) and support the weight of the seat. They are inserted vertically along the double arrow H s into the parallelepipedic apertures (9) of the slider and are secured to it, by a horizontal translation towards the front of the vehicle, with the flange (10) De 'parallelepipedique opening (9 A lock formed by an indexing finger (33) has in the U-shaped cross member (21) and in the rear of the locking system (22) Allows the final maintenance of the seat on the slide avoiding any withdrawal. This lock consists in particular of a vertical finger which is housed vertically and in a vertical translation HN from top to bottom, in its locking position, in the hole (7) of the central portion (5) of the slide (B). This lock is requested by a user when the seat is placed or removed from the sliders A vertical translation H s from the bottom to the top of the latch raises the indexing finger (33) and thus releases the hole (7) the central plate (5) for removing the seat from the slide by a tran horizontal slation towards the rear of the vehicle. These two operations can be done partly at the end of the rails. The buttocks in the form of a reverse F (34) support the upper rear portion of the pawls (12) torsion of the seat attachment on the sliders. This action has the effect of raising the end flange (19) upwards in a rotation on the axis (15) of the rollers (14) and separates the cutting (D) made in the bottom of the rails. The slide can then circulate in the rail. The reverse operation is carried out tors deposition of the seat of the sliders. With the opposite F-shaped butts, the springs (20) apply their pressure to the upper front part of the pawl (12), which causes it to rotate down on the roller axis (15). The rim (19) the pawl (12) then collaborates with the cutting c D of the bottom of the rail.The slides are blocked.
