Abstract
Description
1 L'invention concerne un siège de véhicule automobile. The invention relates to a motor vehicle seat.
Il est connu de réaliser un siège de véhicule automobile à dossier rabattable depuis une configuration sensiblement verticale, notamment un peu inclinée vers l'arrière, vers une configuration sensiblement horizontale d'escamotage qui permet de libérer de l'espace de chargement, ledit siège comprenant un coussin d'appui-tête rabattable, notamment par rotation, depuis une position d'utilisation vers une position rabattue, ledit coussin étant maintenu en position d'utilisation par un moyen de verrouillage. It is known to realize a motor vehicle seat with folding backrest from a substantially vertical configuration, including a little inclined backwards, to a substantially horizontal configuration of retraction which frees up the loading space, said seat comprising a folding headrest cushion, in particular by rotation, from a position of use to a folded position, said cushion being held in the use position by a locking means.
Lorsque le dossier est en configuration verticale, le rabattement du coussin peut être requis pour dégager la vue du conducteur vers la baie vitrée arrière. When the backrest is in the upright configuration, the folding of the cushion may be required to clear the driver's view to the rear window.
Par ailleurs, lorsque le coussin n'est pas rabattu, il peut interférer avec un élément périphérique, notamment un dossier de siège situé à l'avant du siège objet de l'invention, lors du rabattement du dossier. Furthermore, when the cushion is not folded, it can interfere with a peripheral element, including a seat backrest located at the front of the seat object of the invention, when folding the backrest.
II en résulte l'obligation pour l'usager du véhicule de rabattre le coussin avant de réaliser le rabattement du dossier. Une telle manoeuvre s'avère peu ergonomique et l'invention a pour but de pallier cet inconvénient. This results in the obligation for the user of the vehicle to fold down the cushion before folding the backrest. Such a maneuver is not very ergonomic and the invention aims to overcome this disadvantage.
A cet effet, et selon un premier aspect, l'invention propose un siège de véhicule 25 automobile à dossier rabattable depuis une configuration sensiblement verticale vers une configuration sensiblement horizontale, ledit siège comprenant un coussin d'appui-tête rabattable depuis une position d'utilisation vers une position rabattue, ledit coussin étant maintenu en position d'utilisation par un moyen de verrouillage, ledit moyen pouvant déverrouillé selon deux modes : 30 • par un bouton actionné manuellement alors que ledit dossier est en configuration verticale, • par un organe d'actionnement monté sur ledit siège de façon à être actionné par rabattement dudit dossier.20 Notons que dans cette description, les termes de positionnement dans l'espace (haut, inférieur, latéral, arrière, vertical, horizontal, ...) sont pris en référence au siège disposé dans le véhicule avec son dossier en configuration sensiblement verticale. For this purpose, and according to a first aspect, the invention proposes a motor vehicle seat with folding backrest from a substantially vertical configuration to a substantially horizontal configuration, said seat comprising a headrest cushion foldable from a position of use to a folded position, said cushion being held in the position of use by a locking means, said means being unlocked in two modes: • by a button actuated manually while said file is in a vertical configuration, • by an actuator actuation mounted on said seat so as to be actuated by folding said folder. Note that in this description, the terms of positioning in the space (top, bottom, side, rear, vertical, horizontal, ...) are taken with reference to the seat disposed in the vehicle with its backrest in substantially vertical configuration.
L'agencement proposé permet de réaliser un rabattement automatique du coussin lorsqu'il est en position d'utilisation et que l'on opère un rabattement du dossier. L'usager n'a donc pas à réaliser le rabattement du coussin avant celui du dossier. The proposed arrangement allows for an automatic folding of the cushion when in the use position and that one operates a folding of the folder. The user does not have to do the folding of the cushion before the backrest.
Il en résulte une amélioration de l'ergonomie de manipulation. 15 D'autres particularités et avantages de l'invention apparaîtront dans la description qui suit, faite en référence aux figures jointes représentant de manière partielle un siège selon une réalisation : • la figure 1 est une vue arrière d'un coussin d'appui-tête pourvu d'une 20 armature de montage, ledit coussin étant en position d'utilisation, • la figure 2 est une vue après coupe B-B du haut de siège, le coussin d'appui-tête étant verrouillé en position d'utilisation (2a), déverrouillé en position d'utilisation (2b) et en position rabattue (2c), • la figure 3 est une vue après coupe C-C du haut de siège, le coussin 25 d'appui-tête étant verrouillé en position d'utilisation (3a), déverrouillé en position d'utilisation (3b) et en position rabattue (3c), • la figure 4 est une vue après coupe A-A du haut de siège, le coussin d'appui-tête étant verrouillé en position d'utilisation (4a) et déverrouillé en position d'utilisation (4b), 30 • la figure 5 est une vue latérale après coupe verticale du dossier de siège pourvu de l'appui-tête, le coussin d'appui-tête étant verrouillé en position d'utilisation avec le dossier en configuration verticale (5a) et en position10 3 rabattue avec le dossier en configuration intermédiaire de rabattement (5b), un agrandissement de la zone inférieure de dossier étant représenté par ailleurs. This results in improved handling ergonomics. Other features and advantages of the invention will become apparent from the description which follows, made with reference to the appended figures partially showing a seat according to one embodiment: FIG. 1 is a rear view of a support cushion; head having a mounting frame, said cushion being in the position of use; FIG. 2 is a view after section BB of the seat top, the headrest cushion being locked in the use position (2a ), unlocked in the use position (2b) and in the folded position (2c); • FIG. 3 is a view after cutting CC of the seat top, the headrest pad 25 being locked in the position of use ( 3a), unlocked in the use position (3b) and in the folded position (3c), • FIG. 4 is an AA cut-away view of the seat top, the headrest pad being locked in the use position ( 4a) and unlocked in the use position (4b), 30 • the figure e 5 is a side view after vertical section of the seat backrest provided with the headrest, the headrest cushion being locked in position of use with the backrest in vertical configuration (5a) and in position 3 folded with the backrest in the intermediate folding configuration (5b), an enlargement of the lower file area being represented elsewhere.
En référence aux figures, on décrit un siège 1 de véhicule automobile à dossier 2 rabattable depuis une configuration sensiblement verticale - ici un peu inclinée vers l'arrière û vers une configuration sensiblement horizontale non représentée û le passage d'une configuration à l'autre se faisant ici par rotation û ledit siège comprenant un coussin 3 d'appui-tête rabattable depuis une position d'utilisation vers une position rabattue, ici vers l'arrière, ledit coussin étant maintenu en position d'utilisation par un moyen de verrouillage 4, ledit moyen pouvant être déverrouillé selon deux modes : • par un bouton 5 actionné manuellement alors que ledit dossier est en configuration verticale, • par un organe 6 d'actionnement monté sur ledit siège de façon à être actionné par rabattement dudit dossier. Referring to the figures, there is described a seat 1 of a motor vehicle with backrest 2 folding from a substantially vertical configuration - here a little inclined backwards - to a substantially horizontal configuration not shown - the passage from one configuration to another being rotated here - said seat comprising a headrest cushion 3 foldable from a use position to a folded position, here to the rear, said cushion being held in the use position by a locking means 4 said means being unlockable in two modes: by a button 5 actuated manually while said backrest is in a vertical configuration, by an actuating member 6 mounted on said seat so as to be actuated by folding said backrest.
Selon une réalisation, le siège 1 comprend en outre un moyen de contrainte élastique non représenté, par exemple sous forme d'un ressort, disposé de façon à exercer sur le coussin 3 une contrainte vers la position rabattue. According to one embodiment, the seat 1 further comprises a not shown elastic stress means, for example in the form of a spring, arranged to exert on the cushion 3 a constraint to the folded position.
Selon la réalisation représentée, le coussin 3 comprend une structure 8 rigide û notamment à base de matériau plastique moulé û recouverte ici d'un matériau de rembourrage 9 û par exemple à base de mousse souple û ladite structure étant montée en rotation sur une armature 10 de montage û ici sous forme d'un tube métallique conformé sensiblement en U renversé et replié vers l'avant -. According to the embodiment shown, the cushion 3 comprises a rigid structure 8 - in particular based on molded plastic material - covered here with a cushioning material 9 - for example based on flexible foam - said structure being rotatably mounted on a frame 10 mounting here - in the form of a metal tube shaped substantially U inverted and folded forwards -.
L'armature 10 est associée au dossier 2, notamment par insertion dans des logements non représentés prévus en haut de dossier 2. Le moyen de verrouillage 4 comprend une platine 11 fixée sur l'armature 10, ladite platine étant pourvue d'une encoche 12, et un verrou 13 prévu sur la30 4 structure 8 et agencé pour coopérer avec ladite encoche lorsque ledit coussin est en position d'utilisation. The armature 10 is associated with the back 2, in particular by insertion in not shown housing provided at the top of the backrest 2. The locking means 4 comprises a plate 11 fixed to the armature 10, said plate being provided with a notch 12 and a latch 13 provided on the structure 4 and arranged to cooperate with said notch when said cushion is in use position.
Selon une variante non représentée, la platine 11 peut comprendre au moins deux encoches 12, ceci de manière à permettre un réglage angulaire du coussin 3. According to a variant not shown, the plate 11 may comprise at least two notches 12, so as to allow angular adjustment of the cushion 3.
Selon la réalisation représentée, le verrou 13 est sous forme d'une lame dont une extrémité 14 est montée en rotation, le bouton 5 étant disposé en extrémité libre 15 de ladite lame de manière à permettre l'actionnement manuel en rotation de ladite lame. According to the embodiment shown, the latch 13 is in the form of a blade whose one end 14 is rotatably mounted, the button 5 being disposed at the free end 15 of said blade so as to allow manual actuation in rotation of said blade.
En outre, le verrou 13 est pourvu d'un ressort 16 de rappel en verrouillage. In addition, the latch 13 is provided with a spring 16 locking return.
L'organe 6 d'actionnement, quant à lui, est sous la forme d'un câble 17 dont une extrémité est pourvue d'un crochet 18 monté coulissant par rapport à l'armature 10. The actuating member 6, in turn, is in the form of a cable 17 whose end is provided with a hook 18 slidably mounted relative to the armature 10.
Le crochet 18 entre en interaction avec le verrou 13 lorsque le coussin 3 est en position d'utilisation, le câble 17 étant monté de manière à être actionné en traction lorsque le dossier 2 est actionné en rabattement, de sorte que ledit verrou se dégage de l'encoche 12 par traction dudit crochet et que ledit coussin se rabatte vers la position rabattue. The hook 18 interacts with the latch 13 when the cushion 3 is in the position of use, the cable 17 being mounted so as to be actuated in tension when the backrest 2 is actuated in folding, so that said lock is released from the notch 12 by pulling said hook and said cushion folds to the folded position.
Comme représenté en figure 5, l'actionnement du câble 17 en traction est réalisé au moyen d'un galet 20 solidaire du dossier 2, ledit galet exerçant une déviation dudit câble lors du rabattement dudit dossier. As shown in Figure 5, the actuation of the cable 17 in traction is achieved by means of a roller 20 secured to the backrest 2, said roller exerting a deflection of said cable during the folding of said folder.
Un ressort 19 de renvoi du crochet 18 est prévu pour disposer ledit crochet en position d'interagir avec le verrou 13 lorsqu'on relève le dossier 2 vers la configuration verticale, puis manuellement le coussin 3 en position d'utilisation. A hook return spring 19 is provided to arrange said hook in position to interact with the latch 13 when the backrest 2 is raised to the vertical configuration, then manually the cushion 3 in the use position.
