Une glissière de ce type est connue notamment du document FR 2 768 670.  A slide of this type is known in particular from document FR 2 768 670.
Dans la glissière connue, la partie de fixation de la lame du verrou est décalée verticalement par rapport au reste de la lame. La lame présente alors deux coudes transversaux et une portion sensiblement verticale reliant la partie de fixation au reste de la lame. Cette portion sensiblement verticale est ajourée pour permettre le passage d'une branche d'un palonnier permettant de faire passer la partie de verrouillage de la position verrouillée à la position déverrouillée.  In the known slide, the fastening portion of the blade of the lock is offset vertically relative to the rest of the blade. The blade then has two transverse elbows and a substantially vertical portion connecting the attachment portion to the rest of the blade. This substantially vertical portion is perforated to allow the passage of a leg of a spreader for passing the locking portion of the locked position to the unlocked position.
Le verrou d'une telle glissière présente une structure complexe nécessitant une fabrication précise, et peut présenter des problèmes de fragilité qui réduisent la longévité du verrou et de la glissière.  The lock of such a slide has a complex structure requiring precise manufacture, and may have brittleness problems that reduce the longevity of the lock and the slide.
En outre, la fixation du verrou par l'intermédiaire de deux emboutis sur le profilé de manière à presser les bords de la partie de fixation implique un montage complexe et augmente ainsi le temps de montage. Une autre glissière du type précitée et présentant notamment les problèmes évoqués précédemment en termes de longévité est connue du document EP 0 752 338. In addition, the fixing of the latch by means of two stampings on the profile so as to press the edges of the fixing part involves a complex assembly and thus increases the assembly time. Another slide of the aforementioned type and having in particular the problems mentioned previously in terms of longevity is known from EP 0 752 338.
L'invention vise à pallier les problèmes évoqués ci-dessus.  The invention aims to overcome the problems mentioned above.
A cet effet, selon un premier aspect, l'invention propose une glissière du type précité dans laquelle le verrou comprend en outre deux pattes de fixation s'étendant globalement selon la direction verticale en regard l'une de l'autre, respectivement depuis les bords longitudinaux de la partie de fixation de la lame, lesdites pattes de fixation étant adaptées pour être fixées aux ailes du premier profilé.  For this purpose, according to a first aspect, the invention proposes a slide of the aforementioned type in which the lock further comprises two fastening tabs extending generally in the vertical direction facing each other, respectively since the longitudinal edges of the fastening portion of the blade, said fastening tabs being adapted to be fixed to the wings of the first section.
Ainsi, le verrou selon l'invention peut comprendre une lame qui s'étend sensiblement dans un plan et dont la structure simplifiée est facile à fabriquer. La résistance du verrou est, par ailleurs, améliorée du fait de la meilleure répartition des contraintes s'exerçant sur la lame par rapport à un verrou comprenant une lame présentant un ou plusieurs coudes transversaux où les contraintes se concentrent lorsque la lame est déformée. La longévité du verrou et de la glissière s'en trouve améliorée.  Thus, the lock according to the invention may comprise a blade which extends substantially in a plane and whose simplified structure is easy to manufacture. The resistance of the lock is, moreover, improved because of the better distribution of the stresses exerted on the blade relative to a lock comprising a blade having one or more transverse bends where the stresses are concentrated when the blade is deformed. The longevity of the lock and the slide is improved.
De plus, la partie de fixation du verrou présentant une forme en U avec les pattes de fixation disposées le long des ailes du premier profilé permet d'assurer une fixation stable du verrou avec un encombrement réduit de l'espace entre les ailes du premier profilé.  In addition, the fastening portion of the latch having a U-shape with the fastening tabs disposed along the flanges of the first section makes it possible to ensure a stable fastening of the latch with a small space requirement of the space between the flanges of the first section. .
Les pattes de fixation et le premier profilé peuvent comprendre des organes de fixation complémentaires constitués par au moins une ouverture ménagée sur l'un des éléments choisi parmi les pattes de fixation et le premier profilé, et au moins une languette d'encliquetage élastiquement déformable adaptée pour pouvoir pénétrer dans l'ouverture sur l'autre élément choisi parmi les pattes de fixation et le premier profilé. Ces dispositions permettent notamment de simplifier le montage de la glissière en prévoyant une fixation du verrou sur le premier profilé par encliquetage en déplaçant le verrou et le profilé l'un par rapport à l'autre dans une seule direction. Ces dispositions permettent également d'améliorer l'adaptabilité du verrou à différents types de glissière et notamment à différentes dimensions de profilé. Un même verrou peut ainsi être utilisé pour des profilés de dimensions différentes dont seule la position des organes de fixation doit être ajustée.  The fastening tabs and the first section may comprise complementary fastening members consisting of at least one opening formed on one of the elements chosen from the fastening tabs and the first section, and at least one adapted elastically deformable snap-fitting tongue. to be able to penetrate into the opening on the other element selected from the fastening lugs and the first profile. These arrangements make it possible in particular to simplify the mounting of the slide by providing a fastening of the lock on the first profile snap by moving the lock and the profile relative to each other in one direction. These arrangements also make it possible to improve the adaptability of the lock to different types of slide and in particular to different profile dimensions. The same lock can thus be used for profiles of different dimensions which only the position of the fasteners must be adjusted.
La glissière peut en outre comprendre un dispositif d'actionnement adapté pour déplacer la partie de verrouillage de la lame depuis la position verrouillée vers la position déverrouillée. The slide may further include an actuator adapted to move the locking portion of the blade from the locked position to the unlocked position.
Dans un mode de réalisation, le premier profilé peut présenter une ouverture ménagée en regard de la partie de verrouillage de la lame, et le dispositif d'actionnement peut comprendre un plot monté sur la partie de verrouillage de la lame et s'étendant au travers de l'ouverture dans la position verrouillée de la partie de verrouillage. In one embodiment, the first section may have an opening arranged opposite the locking portion of the blade, and the actuating device may comprise a stud mounted on the blade locking portion and extending through the opening in the locked position of the locking portion.
Dans un autre mode de réalisation, les premier et deuxième profilés peuvent définir entre eux un espace intérieur dans lequel est placé le verrou, et le dispositif d'actionnement peut comprendre un palonnier comportant une branche, ladite branche s'étendant globalement selon la direction longitudinale entre une première extrémité disposée en dehors de l'espace intérieur et une deuxième extrémité disposée à l'intérieur de l'espace intérieur. Dans ce mode de réalisation, l'ensemble de la lame est situé sous la branche du palonnier.  In another embodiment, the first and second profiles may define between them an interior space in which the lock is placed, and the actuating device may comprise a spreader having a branch, said branch extending generally in the longitudinal direction. between a first end disposed outside the inner space and a second end disposed within the interior space. In this embodiment, the entire blade is located under the branch of the rudder.
Le dispositif d'actionnement peut alors comprendre en outre un support pourvu d'un logement ouvert selon la direction longitudinale et adapté pour loger la deuxième extrémité de la branche, ledit support étant fixé aux pattes de fixation du verrou.  The actuating device may then further comprise a support provided with a housing open in the longitudinal direction and adapted to accommodate the second end of the branch, said support being fixed to the latches of the latch.
En particulier, le support peut comprendre au moins une paroi de fixation délimitant le logement perpendiculairement aux directions longitudinale et verticale, ladite paroi de fixation étant disposée en regard de l'une des pattes de fixation du verrou, la paroi de fixation et la patte de fixation comprenant des organes de fixation complémentaires constitués par au moins une ouverture ménagée sur l'un des éléments choisi parmi la paroi de fixation et la patte de fixation, et au moins une languette d'encliquetage élastiquement déformable adaptée pour pouvoir pénétrer dans l'ouverture sur l'autre élément choisi parmi la paroi de fixation et la patte de fixation.  In particular, the support may comprise at least one fixing wall delimiting the housing perpendicularly to the longitudinal and vertical directions, said fixing wall being arranged facing one of the bolt fixing lugs, the fixing wall and the lug of the latch. fastening comprising complementary fixing members constituted by at least one opening formed on one of the elements chosen from the fixing wall and the fixing lug, and at least one resiliently deformable latching tongue adapted to be able to penetrate into the opening on the other element chosen from the fixing wall and the fixing lug.
En outre, la deuxième extrémité de la branche du palonnier peut comporter au moins une encoche, et le support peut comprendre au moins une languette d'encliquetage élastiquement déformable s'étendant dans le logement et adaptée pour pénétrer dans l'encoche.  In addition, the second end of the leg of the lifter may comprise at least one notch, and the support may comprise at least one resiliently deformable latching tongue extending into the housing and adapted to penetrate the notch.
Le support peut comprendre un fond délimitant le logement selon la direction verticale et disposé à proximité de la lame du verrou, et une surface de guidage opposée au fond, la surface de guidage étant inclinée en se rapprochant du fond depuis une partie d'appui agencée à proximité de la partie de verrouillage de la lame du verrou, vers une partie de butée agencée à distance de la partie de verrouillage de la lame du verrou, la partie d'appui de la surface de guidage étant en appui contre une surface intérieure du premier profilé délimitant l'espace intérieur selon la direction verticale, de sorte à guider un pivotement de la branche par rapport au premier profilé autour d'un axe perpendiculaire aux directions longitudinale et verticale.  The support may comprise a bottom delimiting the housing in the vertical direction and disposed near the blade of the lock, and a guide surface opposite the bottom, the guide surface being inclined towards the bottom from a support portion arranged near the locking portion of the latch blade, towards a stop portion arranged at a distance from the locking portion of the latch blade, the bearing portion of the guide surface bearing against an inner surface of the latch blade; first section delimiting the interior space in the vertical direction, so as to guide a pivoting of the branch relative to the first section about an axis perpendicular to the longitudinal and vertical directions.

Le siège 1 comporte une assise 2, qui s'étend globalement horizontalement, et un dossier 3, qui est monté sur l'assise 2 et qui s'étend globalement selon une direction verticale Z perpendiculaire au plancher 4. L'assise 2 est montée sur le plancher 4 par l'intermédiaire d'un système de glissières 5 pour permettre un déplacement du siège 1 selon une direction longitudinale X horizontale, vers l'avant et vers l'arrière, par rapport au plancher 4. In the figures, the same references designate identical or similar elements. Figure 1 shows a seat 1 mounted on a horizontal floor 4 of a vehicle. The seat 1 comprises a seat 2, which extends generally horizontally, and a backrest 3, which is mounted on the seat 2 and which extends generally in a vertical direction Z perpendicular to the floor 4. The seat 2 is mounted on the floor 4 by means of a system of slides 5 to allow a displacement of the seat 1 in a longitudinal direction X horizontally, forwards and backwards, with respect to the floor 4.
Le système de glissières 5 représenté sur la figure 2 comprend deux glissières 10 parallèles, s'étendant selon la direction longitudinale X et écartées l'une de l'autre selon une direction transversale Y horizontale, perpendiculaire à la direction longitudinale X. Chacune des glissières 10 comprend un premier profilé 1 1 , mobile, solidaire de l'assise 2 et un deuxième profilé 12, fixe, solidaire du plancher 4 du véhicule. Dans d'autres modes de réalisation, le premier profilé pourrait être solidarisé au plancher 4 du véhicule et le deuxième profilé pourrait être solidarisé à l'assise 2. En outre, le système de glissières 5 pourrait comprendre une seule glissière 10 ou plus de deux glissières 10.  The slide system 5 shown in Figure 2 comprises two parallel rails 10 extending in the longitudinal direction X and spaced apart from each other in a transverse direction Y horizontal, perpendicular to the longitudinal direction X. Each of the slides 10 comprises a first section 1 1, movable, secured to the seat 2 and a second section 12, fixed, secured to the floor 4 of the vehicle. In other embodiments, the first section could be secured to the floor 4 of the vehicle and the second section could be secured to the seat 2. In addition, the slide system 5 could comprise a single slide 10 or more than two slides 10.
Dans les modes de réalisation représentés, le profilé fixe 12 a une section sensiblement en forme de U ouvert vers le haut, avec une base 15 horizontale reposant sur le plancher 4 du véhicule, et deux ailes 20 s'étendant verticalement depuis la base 15, en regard l'une de l'autre. En particulier, la base 15 présente une partie centrale 16 horizontale, plate, en contact avec le plancher 4 du véhicule, et deux ressauts 17 sensiblement horizontaux qui sont disposés de part et d'autre de la partie centrale 16 à distance du plancher 4. Chacune des ailes 20 comprend un tronçon vertical 21 qui s'étend à partir de l'un des ressauts 17 jusqu'à une extrémité, et une auge 22 rentrante qui s'étend depuis l'extrémité du tronçon vertical 21 jusqu'à un bord libre 23, en étant rabattue intérieurement, c'est-à-dire en direction de l'auge 22 de l'autre aile 20, vers la base 15. Des encoches 24 ouverts selon la direction verticale Z sont formés sur le bord libre 23 des auges 22, en étant régulièrement espacés sur au moins une partie de la longueur du profilé fixe 12.  In the embodiments shown, the fixed profile 12 has a substantially U-shaped section open upwards, with a horizontal base resting on the floor 4 of the vehicle, and two wings 20 extending vertically from the base 15, facing each other. In particular, the base 15 has a flat horizontal central portion 16 in contact with the floor 4 of the vehicle, and two substantially horizontal projections 17 which are arranged on either side of the central portion 16 away from the floor 4. Each of the wings 20 comprises a vertical section 21 which extends from one of the projections 17 to one end, and a reentrant trough 22 which extends from the end of the vertical section 21 to an edge free 23, being folded internally, that is to say in the direction of the trough 22 of the other flange 20, towards the base 15. Open slots 24 in the vertical direction Z are formed on the free edge 23 troughs 22, being regularly spaced over at least a portion of the length of the fixed profile 12.
Le profilé mobile 1 1 a également une section sensiblement en forme de U. La section du profilé mobile 1 1 présente, en particulier, une âme 30 horizontale, et deux ailes 35 s'étendant verticalement depuis l'âme 30, en regard l'une de l'autre. En particulier, chacune des ailes 35 comprend un tronçon vertical 36 qui s'étend depuis l'âme 30 jusqu'à une extrémité, et un rabat 37 qui s'étend depuis l'extrémité du tronçon vertical 36 jusqu'à un bord libre, en étant rabattu extérieurement, c'est-à-dire à l'opposé du rabat 37 de l'autre aile 35, vers l'âme 30. Sur chaque aile 35, le tronçon vertical 36 et le rabat 37 définissent un creux longitudinal dans lequel des fenêtres ouvertes selon la direction verticale Z et équidistantes sont ménagées. The movable profile 1 1 also has a substantially U-shaped section. The section of the movable profile 1 1 has, in particular, a horizontal core 30, and two wings 35 extending vertically from the core 30, opposite the one of the other. In particular, each of the wings 35 comprises a vertical section 36 which extends from the core 30 to one end, and a flap 37 which extends from the end of the vertical section 36 to a free edge, being folded on the outside, that is to say opposite the flap 37 of the other wing 35, towards the web 30. On each wing 35, the vertical section 36 and the flap 37 define a longitudinal hollow in which windows open in the vertical direction Z and equidistant are formed.
Le profilé mobile 1 1 , inversé, c'est-à-dire ouvert vers le bas, est monté entre les ailes 20 du profilé fixe 12 avec l'âme 30 placée en regard et à distance de la base 15 et chacun des rabats 37 pénétrant entre le tronçon vertical 21 et l'auge 22 de l'une des ailes 20 du profilé fixe 12. Le bord libre 23 de l'auge 22 de chacune des ailes 20 du profilé fixe 12 est alors disposé dans le creux longitudinal formé par le tronçon vertical 36 et le rabat 37 de l'aile 35 correspondante du profilé mobile 1 1 . Des organes de roulement, tels que des billes, sont disposées dans des chemins de roulement formés entre les auges 22 du profilé fixe 12 et les rabats 37 du profilé mobile 1 1 , pour permettre un coulissement selon la direction longitudinale X du profilé mobile 1 1 par rapport au profilé fixe 12.  The movable section 1 1, inverted, that is to say open downwards, is mounted between the wings 20 of the fixed profile 12 with the core 30 placed opposite and at a distance from the base 15 and each of the flaps 37 penetrating between the vertical section 21 and the trough 22 of one of the wings 20 of the fixed profile 12. The free edge 23 of the trough 22 of each of the wings 20 of the fixed profile 12 is then disposed in the longitudinal hollow formed by the vertical section 36 and the flap 37 of the corresponding flange 35 of the movable section 1 1. Rolling members, such as balls, are arranged in raceways formed between the troughs 22 of the fixed profile 12 and the flaps 37 of the movable section 1 1, to allow sliding in the longitudinal direction X of the mobile section 1 1. relative to the fixed profile 12.
L'âme 30 et les tronçons verticaux 36 du profilé mobile 1 1 définissent avec la base 15 du profilé fixe 12 un espace intérieur dans lequel un verrou 40 est disposé pour, dans une position verrouillée, boquer le profilé mobile 1 1 par rapport au profilé fixe 12 afin de maintenir le siège 1 dans une position longitudinale souhaitée, et, dans une position déverrouillée, permettre le coulissement du profilé mobile 1 1 par rapport au profilé fixe 12 afin de régler la position longitudinale du siège 1 .  The core 30 and the vertical sections 36 of the movable section 1 1 define with the base 15 of the fixed profile 12 an interior space in which a latch 40 is arranged to, in a locked position, close the movable section 1 1 relative to the profile. fixed 12 in order to maintain the seat 1 in a desired longitudinal position, and, in an unlocked position, allow sliding of the movable section 1 1 relative to the fixed section 12 to adjust the longitudinal position of the seat 1.
Sur les figures 3 à 5, le verrou 40, réalisé par exemple en tôle métallique pliée, comprend une lame 41 élastiquement déformable s'étendant sensiblement dans un plan horizontale XY. La lame 41 présente une partie de fixation 42 et une partie de verrouillage 43 respectivement au voisinage de première 41 a et deuxième 41 b extrémités opposées, écartées l'une de l'autre selon la direction longitudinale X. La lame 41 présente deux bords longitudinaux 41 c opposés s'étendant selon la direction longitudinale X.  In FIGS. 3 to 5, the latch 40, made for example from folded sheet metal, comprises an elastically deformable blade 41 extending substantially in a horizontal plane XY. The blade 41 has an attachment portion 42 and a locking portion 43 respectively in the vicinity of first 41a and second 41b opposite ends, spaced apart from each other in the longitudinal direction X. The blade 41 has two longitudinal edges 41 c opposite extending in the longitudinal direction X.
Sur la partie de fixation 42 de la lame 41 , le verrou 40 comprend en outre deux pattes de fixation 45 s'étendant dans des plans verticaux XZ, en regard l'une de l'autre, respectivement depuis les bords longitudinaux 41 c de la lame 40. Chacune des pattes de fixation 45 est ainsi reliée à la lame 41 par un coude s'étendant selon la direction longitudinale X le long de l'un des bords longitudinaux de la lame 41 . Les pattes de fixation 45 présentent des surfaces intérieures respectives en regard l'une de l'autre et des surfaces extérieures respectives. La partie de fixation 42 constitue ainsi un boîtier en forme de U. En variante, le verrou 40 pourrait comprendre plus de deux pattes de fixation 45 agencées de manière appropriée. En outre, chacune des pattes de fixation 45 est illustrée, dans le mode de réalisation représenté, avec une unique paroi s'étendant dans un plan vertical XZ. En variante, la patte de fixation 45 pourrait s'étendre globalement dans la direction verticale Z, c'est-à-dire présenter un bord, libre ou non, disposé à distance selon la direction verticale Z de la lame 41 . La paroi globalement verticale de la patte de fixation 45 pourrait en outre être prolongée, par exemple par une paroi sensiblement horizontale. On the attachment portion 42 of the blade 41, the latch 40 further comprises two fastening tabs 45 extending in vertical planes XZ facing each other, respectively from the longitudinal edges 41c of the Each attachment tab 45 is thus connected to the blade 41 by a bend extending in the longitudinal direction X along one of the longitudinal edges of the blade 41. The fastening tabs 45 have respective inner surfaces facing each other and respective outer surfaces. The fastening portion 42 thus constitutes a U-shaped casing. Alternatively, the latch 40 could comprise more than two suitably arranged fastening tabs 45. In addition, each of the brackets 45 is illustrated, in the embodiment shown, with a single wall extending in a vertical plane XZ. As a variant, the fixing lug 45 could extend generally in the vertical direction Z, that is to say present an edge, free or not, arranged at a distance in the vertical direction Z of the blade 41. The generally vertical wall of the fixing lug 45 could also be extended, for example by a substantially horizontal wall.
Chacune des pattes de fixation 45 comprend des organes de fixation du verrou 40 au profilé mobile 1 1 . En particulier, les organes de fixation sont constitués par des languettes d'encliquetage 46 élastiquement déformables faisant saillie par rapport à la surface extérieure de la patte de fixation 45 destinée à être placée en regard d'une surface intérieure du profilé mobile 1 1 . Sur chaque patte de fixation 45, deux languettes d'encliquetage 46 obtenues par une découpe et une déformation d'une partie de la patte de fixation 45 sont disposées à distance l'une de l'autre selon la direction longitudinale X.  Each of the fixing lugs 45 comprises fastening members of the lock 40 to the movable section 1 1. In particular, the fixing members are constituted by resiliently deformable latching tongues 46 protruding from the outer surface of the fixing lug 45 intended to be placed facing an inner surface of the movable section 1 1. On each bracket 45, two detent tabs 46 obtained by cutting and deforming a portion of the bracket 45 are arranged at a distance from each other in the longitudinal direction X.
Dans le mode de réalisation représenté, le verrou 40 est fixé au profilé mobile 1 1 en insérant la partie de fixation 42 entre les ailes 35 du profilé mobile 1 1 . Celui-ci présente alors, sur les ailes 35, des ouvertures 48 complémentaires des languettes d'encliquetage et adaptées pour les recevoir. En particulier, en poussant la partie de fixation 42 entre les ailes 35 du profilé mobile 1 1 , les languettes d'encliquetage 46 sont déformées vers l'intérieur jusqu'à ce qu'elles atteignent les ouvertures 48 dans lesquelles elles peuvent s'étendre sous l'effet de leur élasticité. Les pattes de fixation 45 sont ainsi fixées respectivement aux ailes 35 du profilé mobile 1 1 avec les surfaces extérieures des pattes de fixation 45 en contact avec les surfaces intérieures en regard des ailes 35 du profilé mobile 1 1 .  In the embodiment shown, the latch 40 is fixed to the mobile section 1 1 by inserting the fixing portion 42 between the flanges 35 of the movable section 1 January. It then has, on the flanges 35, complementary openings 48 of the detent tabs and adapted to receive them. In particular, by pushing the fixing portion 42 between the flanges 35 of the movable section 1 1, the detent tongues 46 are deformed inwards until they reach the openings 48 in which they can extend. under the effect of their elasticity. The fixing lugs 45 are thus fixed respectively to the wings 35 of the movable profile 1 1 with the outer surfaces of the fastening lugs 45 in contact with the inner surfaces facing the flanges 35 of the movable profile 1 January.
En variante, l'encliquetage du verrou 40 sur le premier profilé pourrait être mis en œuvre de toute autre manière appropriée et, en particulier, au moyen d'une ou plusieurs languettes d'encliquetage portées par l'un ou l'autre des éléments choisi parmi la ou les pattes de fixation 45 du verrou 40, d'une part, et le profilé mobile 1 1 , d'autre part, les languettes d'encliquetage coopérant avec une ou plusieurs ouvertures ménagées sur l'autre élément choisi parmi la ou les pattes de fixation 45 du verrou 40, d'une part, et le profilé mobile 1 1 , d'autre part. L'invention n'est, par ailleurs, pas limitée à une fixation par encliquetage de la partie de fixation 42 du verrou 40 sur le profilé mobile 1 1 . Tout autre de type de fixation, mettant notamment en œuvre des organes de fixation complémentaires sur la patte de fixation et le profilé correspondant, pourrait être prévu. Le verrou 40 pourrait, par ailleurs, être fixé sur le profilé fixe 12.  Alternatively, the locking of the latch 40 on the first section could be implemented in any other suitable manner and, in particular, by means of one or more latching tongues carried by one or other of the elements. chosen from the one or more fastening tabs 45 of the latch 40, on the one hand, and the movable profile 1 1, on the other hand, the latching tabs cooperating with one or more openings formed on the other element chosen from the or the brackets 45 of the latch 40, on the one hand, and the movable section 1 1, on the other hand. The invention is, moreover, not limited to snap fastening of the fastening portion 42 of the latch 40 on the movable section 1 1. Any other fixing type, including implementing additional fasteners on the bracket and the corresponding section, could be provided. The latch 40 could, moreover, be fixed on the fixed profile 12.
A l'opposé de la partie de fixation 42, la partie de verrouillage 43 est quant à elle pourvue de crans 47, au nombre de trois dans le mode de réalisation représenté, s'étendant selon la direction transversale Y, à équidistance les uns des autres, depuis chacun des bords longitudinaux 41 c de la lame 41 . La partie de verrouillage 43 est agencée pour que les crans 47 puissent s'engager dans les encoches 24 des ailes 20 du profilé fixe 12, en passant au travers des fenêtres des ailes 35 du profilé mobile 1 1 . La lame 41 est conformée pour qu'en l'absence de sollicitation extérieure, la partie de verrouillage 43 soit dans une position verrouillée dans laquelle les crans 47 s'engagent dans les encoches 24 des ailes 20 du profilé fixe 12. Le verrou 40 bloque alors le profilé mobile 1 1 par rapport au profilé fixe 12. La partie de verrouillage 43 peut être déplacée selon la direction verticale Z, par une sollicitation exercée sur la partie de verrouillage 43 et conduisant à une déformation de la lame 41 , vers une position déverrouillée dans laquelle elle est écartée du profilé fixe 12, les crans 47 étant dégagés des encoches 24. Le profilé mobile 1 1 peut alors coulisser par rapport au profilé fixe 12 selon la direction longitudinale X. Lorsque la sollicitation est relâchée, la partie de verrouillage 43 revient automatiquement du fait du rappel élastique vers la position verrouillée. Opposite the fixing portion 42, the locking portion 43 is provided with notches 47, three in the embodiment shown, extending in the transverse direction Y, equidistant from each other. others, from each of the longitudinal edges 41c of the blade 41. The locking portion 43 is arranged so that the notches 47 can engage in the notches 24 of the wings 20 of the fixed profile 12, passing through the windows of the wings 35 of the movable section 1 January. The blade 41 is shaped so that in the absence of external stress, the locking portion 43 is in a locked position in which the notches 47 engage in the notches 24 of the wings 20 of the fixed profile 12. The latch 40 blocks then the movable section 1 1 with respect to the fixed profile 12. The locking portion 43 can be moved in the vertical direction Z, by a bias exerted on the locking portion 43 and leading to a deformation of the blade 41, to a position unlocked in which it is spaced apart from the fixed profile 12, the notches 47 being disengaged from the notches 24. The movable profile 1 1 can then slide relative to the fixed profile 12 in the longitudinal direction X. When the bias is released, the locking portion 43 returns automatically due to the elastic return to the locked position.
Pour exercer la sollicitation faisant passer la partie de verrouillage 43 de la position verrouillée à la position déverrouillée, la glissière 10 peut être équipée d'un dispositif d'actionnement.  To exert the biasing passing the locking portion 43 from the locked position to the unlocked position, the slideway 10 may be equipped with an actuating device.
Dans le premier mode de réalisation représenté sur les figures 2 à 5, la deuxième extrémité 41 b de la lame 41 est recourbée de sorte à présenter un retour 51 à distance du reste de la lame 41 selon la direction verticale Z et dirigé vers la première extrémité 41 a. Le dispositif d'actionnement comprend un plot 50 monté sur le retour 51 et s'étendant au travers d'une ouverture 52 ménagée sur l'âme 30 du profilé mobile 1 1 dans la position verrouillée de la partie de verrouillage 43.  In the first embodiment shown in Figures 2 to 5, the second end 41b of the blade 41 is bent so as to have a return 51 remote from the rest of the blade 41 in the vertical direction Z and directed to the first end 41 a. The actuating device comprises a stud 50 mounted on the return 51 and extending through an opening 52 formed on the web 30 of the mobile section 1 1 in the locked position of the locking portion 43.
Un amortisseur 55 pour absorber les bruits produits par des vibrations ou lors du verrouillage de la glissière 10 peut être prévu sur le retour 51 de la lame 41 de manière à être en contact avec le profilé mobile 1 1 dans la position verrouillée de la partie de verrouillage 43.  A damper 55 for absorbing the noise produced by vibrations or when locking the slideway 10 may be provided on the return 51 of the blade 41 so as to be in contact with the movable section 1 1 in the locked position of the part of lock 43.
Les figures 6 à 10 représentent une glissière 10' selon un deuxième mode de réalisation qui diffère principalement de la glissière 10 du premier mode de réalisation en ce que l'organe d'actionnement pour déplacer la partie de verrouillage de la position verrouillée à la position déverrouillée comprend un palonnier 60. Les profilés fixe 12 et mobile 1 1 et le verrou 40 présentant des structures et des agencements analogues à ceux décrit précédemment en relation avec le premier mode de réalisation ne seront pas décrits à nouveau. L'on se référera à la description qui en a déjà été faite ci-dessous pour plus de détails.  Figures 6 to 10 show a slideway 10 'according to a second embodiment which differs mainly from the slideway 10 of the first embodiment in that the actuating member for moving the locking part from the locked position to the position Unlocked includes a spreader 60. The fixed profiles 12 and movable January 1 and the lock 40 having structures and arrangements similar to those described above in connection with the first embodiment will not be described again. Reference is made to the description which has already been made below for more details.
Le palonnier 60 présente une forme générale de U comportant deux branches 61 parallèles qui s'étendent chacune depuis une première extrémité 61 a raccordée à une base jusqu'à une deuxième extrémité, libre, 61 b. Chacune des branches 61 est insérée dans l'espace intérieur entre les profilés fixe 12 et mobile 1 1 de d'une des glissières 10' de telle manière que la branche 61 s'étendant globalement selon la direction longitudinale X avec la première extrémité 61 a disposée en dehors de l'espace intérieur et la deuxième extrémité 61 b disposée à l'intérieur de l'espace intérieur. The spreader 60 has a general U-shape with two parallel branches 61 which each extend from a first end 61 connected to a base to a second end, free, 61 b. Each of the branches 61 is inserted into the interior space between the fixed and movable profiles 11 1 of one of the slides 10 'so that the branch 61 extending generally in the longitudinal direction X with the first end 61 disposed outside the inner space and the second end 61b disposed within the interior space.
Le dispositif d'actionnement comprend en outre un support 65 pourvu d'un logement ouvert selon la direction longitudinale X et adapté pour loger la deuxième extrémité 61 b de la branche 61 .  The actuating device further comprises a support 65 provided with an open housing in the longitudinal direction X and adapted to accommodate the second end 61b of the branch 61.
Sur la figure 7, le support 65, réalisé par exemple en tôle métallique pliée, comprend un boîtier 66 et un levier 67 attenant au boîtier 66 selon la direction longitudinale X.  In FIG. 7, the support 65, made for example of folded sheet metal, comprises a housing 66 and a lever 67 adjoining the housing 66 in the longitudinal direction X.
Le boîtier 66 présente une forme général en U avec un fond 68 s'étendant selon un plan horizontal XY et deux parois de fixation 69 s'étendant dans des plans verticaux XZ, en regard l'une de l'autre, depuis des bords longitudinaux du fond 68. Le fond 68 délimite le logement selon la direction verticale Z et les parois de fixation 69 délimitent le logement selon la direction transversale Y. En variante, le support 65 pourrait comprendre une ou plus de deux parois de fixation 69. Le fond 68 du boîtier 66 se prolonge dans le levier 67 pour en former le fond.  The casing 66 has a generally U-shaped shape with a bottom 68 extending in a horizontal plane XY and two fixing walls 69 extending in vertical planes XZ facing one another from longitudinal edges. The bottom 68 delimits the housing in the vertical direction Z and the fixing walls 69 delimit the housing in the transverse direction Y. Alternatively, the support 65 could comprise one or more attachment walls 69. The bottom 68 of the housing 66 extends into the lever 67 to form the bottom.
Les parois de fixation 69 présentent chacune un bord libre 70 opposé au fond 68, dont une partie d'appui 71 située à proximité du levier 67 est agencée à une distance du fond 68 supérieure à celle d'une partie de butée 72 située à distance du levier 67. Les bords libres des parois de fixation 69 définissent ainsi une surface de guidage 70 inclinée en se rapprochant du fond 68 depuis la partie d'appui 71 agencée à proximité du levier 67, vers la partie de butée 72 agencée à distance du levier 67. L'inclinaison de la surface de guidage 70 par rapport à un plan horizontal XY définit un angle de déverrouillage comme il apparaîtra de la suite de la description.  The fixing walls 69 each have a free edge 70 opposite the bottom 68, a bearing portion 71 located near the lever 67 is arranged at a distance from the bottom 68 greater than that of a stop portion 72 located at a distance The free edges of the attachment walls 69 thus define a guide surface 70 inclined towards the bottom 68 from the bearing portion 71 arranged near the lever 67 towards the abutment portion 72 arranged at a distance from the Lever 67. The inclination of the guide surface 70 with respect to a horizontal plane XY defines an unlocking angle as will be apparent from the following description.
Comme représenté sur la figure 8, chaque paroi de fixation 69 du support 65 comprend deux languettes d'encliquetage 75 élastiquement déformables s'étendant dans le logement. Les languettes d'encliquetage 75 obtenues par une découpe et une déformation d'une partie de la paroi de fixation 69 sont disposées à distance l'une de l'autre selon la direction longitudinale X. Deux paires d'encoches 76 sont ménagées sur la deuxième extrémité 61 b de la branche 61 du palonnier 60 pour pouvoir recevoir les languettes d'encliquetage 75. En variante, une ou plus de deux languettes d'encliquetage 75 pourraient être agencées sur chaque paroi de fixation 69 ou sur tout autre partie du support 65 pour coopérer avec une ou plusieurs encoches complémentaires formées sur la branche 61 du palonnier 60.  As shown in FIG. 8, each attachment wall 69 of the support 65 comprises two resiliently deformable latching tongues 75 extending into the housing. The detent tabs 75 obtained by cutting and deformation of a portion of the attachment wall 69 are arranged at a distance from each other in the longitudinal direction X. Two pairs of notches 76 are provided on the second end 61b of the branch 61 of the spreader 60 to be able to receive the detent tongues 75. As a variant, one or more two detent tongues 75 could be arranged on each fixing wall 69 or on any other part of the support 65 to cooperate with one or more complementary notches formed on the branch 61 of the spreader 60.
En outre, comme représenté sur la figure 9, chacune des parois de fixation 69 comprend des organes de fixation du support 65 à la partie de fixation 42 du verrou 40. En particulier, les organes de fixation sont constitués par des languettes d'encliquetage 73 élastiquement déformable faisant saillie par rapport à une surface extérieure de la paroi de fixation 69 destinée à être placée en regard d'une surface intérieure de l'une des pattes de fixation 45 du verrou 40. Sur chaque paroi de fixation 69, une languette d'encliquetage 73 obtenue par une découpe et une déformation d'une partie de la paroi de fixation 69 est prévue. In addition, as shown in FIG. 9, each of the attachment walls 69 comprises fasteners for the support 65 to the attachment portion 42 of the lock 40. In particular, the fastening members are constituted by locking tongues. 73 resiliently deformable protruding from an outer surface of the fastening wall 69 to be placed opposite an inner surface of one of the fastening tabs 45 of the latch 40. On each fastening wall 69, a tab detent 73 obtained by cutting and deformation of a portion of the attachment wall 69 is provided.
Le support 65 peut ainsi être fixé à la partie de fixation 42 du verrou 40 en insérant le boîtier 66 du support 65 dans le boîtier de la parie de verrouillage 42 du verrou 40, entre les pattes de fixation 45. Les pattes de fixation 45 comportent alors respectivement des ouvertures 74 complémentaires des languettes d'encliquetage 73 et adaptées pour les recevoir. En particulier, en poussant le boîtier 66 du support 65 entre les pattes de fixation 45 du verrou 40, les languettes d'encliquetage 73 sont déformées vers l'intérieur jusqu'à ce qu'elles atteignent les ouvertures 74 dans lesquelles elles peuvent s'étendre sous l'effet de leur élasticité. Les parois de fixation 69 du support 65 sont ainsi fixées respectivement aux pattes de fixation 45 du verrou 40.  The support 65 can thus be fixed to the attachment portion 42 of the latch 40 by inserting the housing 66 of the support 65 in the housing of the locking portion 42 of the latch 40, between the fixing lugs 45. The fixing lugs 45 comprise then respectively complementary openings 74 of the detent tabs 73 and adapted to receive them. In particular, by pushing the housing 66 of the support 65 between the fastening tabs 45 of the latch 40, the detent tabs 73 are deformed inwards until they reach the openings 74 in which they can be located. extend under the effect of their elasticity. The fixing walls 69 of the support 65 are thus fixed respectively to the fixing lugs 45 of the latch 40.
En variante, l'encliquetage et plus généralement la fixation du support 65 sur la partie de fixation 42 du verrou 40 pourraient être réalisés de toute autre manière appropriée.  Alternatively, the latching and more generally the fixing of the support 65 on the attachment portion 42 of the latch 40 could be made in any other appropriate manner.
Le fond 68 du support 65 est disposé, au niveau du boîtier 66, à proximité de la lame 41 du verrou 40 et, au niveau du levier 67, en contact avec la partie de verrouillage 43 de la lame 41 .  The bottom 68 of the support 65 is arranged, at the housing 66, near the blade 41 of the latch 40 and, at the lever 67, in contact with the locking portion 43 of the blade 41.
Le verrou 40 peut ensuite être monté sur le profilé mobile 1 1 par encliquetage comme décrit précédemment. La partie d'appui 71 de la surface de guidage 70 du support 65 est alors en appui contre une surface intérieure de l'âme 30 du profilé mobile 1 1 délimitant l'espace intérieur selon la direction verticale Z. La partie de butée 72 est quant à elle à distance de la surface intérieure de l'âme 30 du profilé mobile 1 1 (figure 7). La deuxième extrémité 61 b de la branche du palonnier 60 peut être emmanchée dans le support 65 et y être fixée par encliquetage comme décrit précédemment.  The latch 40 can then be mounted on the movable section 1 1 snap as described above. The bearing portion 71 of the guide surface 70 of the support 65 is then resting against an inner surface of the core 30 of the movable profile 1 1 delimiting the internal space in the vertical direction Z. The abutment portion 72 is as for it at a distance from the inner surface of the core 30 of the movable section 1 1 (FIG. 7). The second end 61b of the limb of the spreader 60 can be fitted into the support 65 and be snap-fastened as previously described.
Comme représenté sur la figure 10, lorsqu'une sollicitation dans le sens de la flèche F est exercée sur première extrémité 61 a de la branche 61 du palonnier 60 par un utilisateur voulant régler la position longitudinale de son siège 1 , un pivotement de la branche 61 autour d'un axe transversal est guidé par la partie d'appui 71 de la surface de guidage du support 65. Le pivotement se poursuit jusqu'à ce que la partie de butée 42 de la surface de guidage 70 du support 65 vienne en butée contre l'âme 30 du profilé mobile 1 1 . Ce faisant, la deuxième extrémité 61 a de la branche 61 déplace la partie de verrouillage 43 du verrou 40 vers la base 15 du profilé fixe 12, par l'intermédiaire du levier 67 du support 65. La partie de verrouillage 43 passe dans la position déverrouillée. Lorsque la sollicitation est relâchée, la partie de verrouillage 43 du verrou 40 est rappelée vers la position verrouillée. As shown in FIG. 10, when a bias in the direction of the arrow F is exerted on the first end 61a of the branch 61 of the spreader 60 by a user wanting to adjust the longitudinal position of his seat 1, a pivoting of the branch 61 about a transverse axis is guided by the bearing portion 71 of the guide surface of the support 65. The pivoting continues until the abutment portion 42 of the guide surface 70 of the support 65 comes into position. abutment against the web 30 of the mobile section 1 1. In doing so, the second end 61a of the branch 61 moves the locking portion 43 of the latch 40 towards the base 15 of the fixed profile 12, via the lever 67 of the support 65. The locking portion 43 passes into the position unlocked. When the bias is released, the locking portion 43 of the latch 40 is biased to the locked position.
