Abstract
Description
L'invention concerne un siège de véhicule automobile.The invention relates to a motor vehicle seat.
II est connu, par exemple du document EP-0 666 194, de réaliser des sièges de véhicules automobiles comprenant un coussin d'assise, ledit coussin comprenant un corps fixe, s'étendant au moins à l'avant dudit coussin, et un bloc mobile réglable entre une position escamotée, où il est disposé dans le prolongement du corps, le corps et le bloc formant une surface de coussin sensiblement plane destinée à recevoir un passager adulte, et une position io déployée vers le haut, permettant de former surface d'assise rehaussée pour un enfant. It is known, for example from EP-0 666 194, to make motor vehicle seats comprising a seat cushion, said cushion comprising a fixed body, extending at least in front of said cushion, and a block movable adjustable between a retracted position, where it is disposed in the extension of the body, the body and the block forming a substantially planar cushion surface for receiving an adult passenger, and an upwardly deployed position for forming a surface raised seat for a child.
Les agencements connus sont généralement de réalisation complexe et donc d'un coût important, incompatible avec les exigences économiques de l'industrie 15 automobile. The known arrangements are generally of complex construction and therefore of a significant cost, incompatible with the economic requirements of the automotive industry.
De plus, dans une réalisation selon le document EP-0 666 194, le bloc mobile subit une translation vers le haut et forme une surface d'assise pour l'enfant sensiblement plane. Une telle réalisation présente des inconvénients en terme de confort et de sécurité. En effet, une surface d'assise présente des risques de sous-marinage en cas de choc avant. In addition, in one embodiment according to EP-0 666 194, the movable block is translated upwards and forms a substantially planar seating surface for the child. Such an embodiment has disadvantages in terms of comfort and safety. Indeed, a seating surface presents risks of submarining in case of impact before.
L'invention a pour but de pallier ces inconvénients en proposant un siège pourvu d'un tel agencement, selon une réalisation simplifiée et donc économique et dans laquelle le bloc mobile est incliné lorsqu'il est déployé, améliorant ainsi le confort et la sécurité de l'enfant. The invention aims to overcome these disadvantages by providing a seat provided with such an arrangement, in a simplified embodiment and therefore economical and wherein the movable block is inclined when deployed, thereby improving the comfort and safety of the child.
A cet effet, l'invention propose un siège de véhicule automobile comprenant une armature d'assise et une armature de dossier, un coussin d'assise étant disposé sur ladite armature d'assise, ledit coussin comprenant un corps fixe, s'étendant au moins à l'avant dudit coussin, et un bloc mobile vers le haut de façon réversible, le bloc étant articulé en rotation selon un axe transversal horizontal, situé dans sa partie arrière, de sorte que le bloc soit réglable entre une position escamotée, où il est disposé dans le prolongement dudit corps, le corps et le bloc formant une surface de coussin sensiblement plane, et une position déployée, où sa partie avant est relevée par rapport au corps fixe. For this purpose, the invention proposes a motor vehicle seat comprising a seat frame and a backrest frame, a seat cushion being disposed on said seat frame, said cushion comprising a fixed body, extending to less at the front of said cushion, and a block movable upwards reversibly, the block being articulated in rotation along a horizontal transverse axis, situated in its rear part, so that the block is adjustable between a retracted position, where it is disposed in the extension of said body, the body and the block forming a substantially flat cushion surface, and an extended position, where its front portion is raised relative to the fixed body.
Les termes de positionnement (transversal, horizontal, avant, arrière, haut, bas) 5 utilisés dans ce descriptif sont pris en référence à un siège une fois monté dans un véhicule automobile. The positioning terms (transverse, horizontal, front, rear, top, bottom) used in this specification are taken in reference to a seat once mounted in a motor vehicle.
Selon une réalisation, le bloc mobile comprend, sous sa partie avant, une béquille articulée en rotation, selon un axe secondaire, parallèle à l'axe io transversal horizontal, entre une position d'utilisation et une position de non utilisation, l'extrémité libre de ladite béquille coopérant en position d'utilisation avec un dispositif de blocage associé à l'armature d'assise. According to one embodiment, the movable block comprises, under its front part, a crutch articulated in rotation, along a secondary axis, parallel to the horizontal transverse axis, between a position of use and a non-use position, the end free of said stand cooperating in the use position with a locking device associated with the seat frame.
Une telle réalisation présente une grande simplicité de réalisation par rapport à 15 l'art antérieur. Such an embodiment has a great simplicity of realization compared to the prior art.
D'autres particularités et avantages de l'invention apparaîtront dans la description qui suit, faite en référence aux figures jointes dans lesquelles: É la figure 1 est une vue schématique en perspective d'un siège selon l'invention, le bloc mobile étant en position déployée, É la figure 2 est une vue schématique latérale d'un siège selon l'invention avec le bloc mobile en position déployée (a), une vue de détail présentant le bloc mobile respectivement en position déployée (b) et en position escamotée (c) et la béquille respectivement en position d'utilisation (b) et de non utilisation (c). Other features and advantages of the invention will appear in the description which follows, made with reference to the attached figures in which: FIG 1 is a schematic perspective view of a seat according to the invention, the movable block being in 2 is a schematic side view of a seat according to the invention with the moving block in the deployed position (a), a detail view showing the movable block respectively in the deployed position (b) and in the retracted position (c) and the stand respectively in position of use (b) and non-use (c).
En référence à la figure 1, on décrit à présent un siège de véhicule automobile 1 comprenant une armature d'assise 2 et une armature de dossier 3, un coussin d'assise 4 étant disposé sur ladite armature d'assise, ledit coussin comprenant un corps fixe 5, s'étendant au moins à l'avant dudit coussin, et un bloc mobile 6 vers le haut de façon réversible. Le bloc 6 est articulé en rotation selon un axe transversal horizontal 7, situé dans sa partie arrière. Le bloc est ainsi réglable entre une position escamotée, où il est disposé dans le prolongement du corps 5, le corps 5 et le bloc 6 formant une surface de coussin sensiblement plane, et une position déployée, où la partie avant du bloc 6 est relevée par rapport au corps fixe 5. Referring to Figure 1, there is now described a motor vehicle seat 1 comprising a seat frame 2 and a backrest frame 3, a seat cushion 4 being disposed on said seat frame, said cushion comprising a fixed body 5, extending at least in front of said cushion, and a movable block 6 upwards reversibly. The block 6 is articulated in rotation along a horizontal transverse axis 7, located in its rear part. The block is thus adjustable between a retracted position, where it is disposed in the extension of the body 5, the body 5 and the block 6 forming a substantially flat cushion surface, and an extended position, where the front portion of the block 6 is raised relative to the fixed body 5.
Selon la réalisation représentée, le corps 5 s'étend en outre sur les parties latérales du coussin d'assise 4, de sorte à présenter une forme générale en U entourant le bloc mobile 6. Le bloc mobile 6 est alors emboîté dans le corps 5 lorsqu'il est en position escamotée. According to the embodiment shown, the body 5 further extends over the lateral parts of the seat cushion 4, so as to have a generally U-shaped surrounding the movable block 6. The movable block 6 is then fitted into the body 5 when in the retracted position.
Selon la réalisation présentée sur la figure 2, le bloc mobile 6 comprend, sous sa partie avant, une béquille 8 articulée en rotation, selon un axe secondaire, parallèle à l'axe transversal horizontal 7, entre une position d'utilisation et une position de non utilisation. L'extrémité libre 9 de la béquille 8 coopère en position d'utilisation avec un dispositif de blocage 10 associé à l'armature d'assise 2. According to the embodiment shown in FIG. 2, the movable block 6 comprises, under its front part, a crutch 8 articulated in rotation, along a secondary axis, parallel to the horizontal transverse axis 7, between a position of use and a position of non-use. The free end 9 of the stand 8 cooperates in the position of use with a locking device 10 associated with the seat frame 2.
La béquille 8 est formée, par exemple, d'une tringle conformée de sorte à pouvoir coopérer avec le dispositif de blocage 10. The stand 8 is formed, for example, of a rod shaped so as to cooperate with the locking device 10.
L'enfant, représenté schématiquement sur la figure 2a, est assis sur le bloc 6, 20 ses mollets reposant sur la partie avant du corps 5, ce qui lui procure un bon confort. The child, shown diagrammatically in Figure 2a, sits on the block 6, 20 his calves resting on the front part of the body 5, which gives him a good comfort.
En outre, le fait que les cuisses de l'enfant forment avec son torse un angle plus faible que dans une position d'assise usuelle, ceci en raison de l'inclinaison du bloc 6 en position déployée, limite les risques de sous-marinage en cas de choc avant. In addition, the fact that the thighs of the child form with his torso a lower angle than in a usual sitting position, this due to the inclination of the block 6 in the deployed position, limits the risk of submarining in case of shock before.
Le dispositif de blocage 10 représenté comprend une pluralité de crans 15, écartés selon la direction horizontale, coopérant avec l'extrémité libre 9. Les crans 15 sont agencés de sorte à permettre un réglage de la béquille 8 en position d'utilisation, afin de régler l'inclinaison du bloc mobile 6. The locking device 10 shown comprises a plurality of notches 15, spaced in the horizontal direction, cooperating with the free end 9. The notches 15 are arranged to allow adjustment of the stand 8 in the use position, in order to adjust the inclination of the moving block 6.
Le dispositif de blocage 10 comprend en outre une première piste de coulissement 12 de l'extrémité libre 9, agencée pour permettre le guidage de ladite extrémité en position d'utilisation, et une deuxième piste de coulissement 13, permettant le retour de ladite extrémité en position de non utilisation. Le passage de l'extrémité 9 de la première 12 à la deuxième 13 piste se fait, lors du retour en position de non utilisation, au travers d'un clapet anti- retour 14. The locking device 10 further comprises a first sliding track 12 of the free end 9, arranged to allow the guiding of said end in the use position, and a second sliding track 13, allowing the return of said end in non-use position. The passage from the end 9 of the first 12 to the second 13 track is, when returning to the non-use position, through a non-return valve 14.
Le clapet 14 peut être formé d'un ressort agencé pour permettre le passage non réversible de l'extrémité 9 de la première 12 à la deuxième 13 piste. The valve 14 may be formed of a spring arranged to allow the non-reversible passage of the end 9 of the first 12 to the second 13 track.
Comme présenté sur la figure 2c, la béquille 8 s'étend librement, sans io engagement avec les crans, lorsqu'elle est en position de non utilisation. As shown in FIG. 2c, the stand 8 extends freely, without engagement with the notches, when in the non-use position.
La manipulation du bloc 6 de sa position escamotée à sa position déployée, et vice-versa, peut être effectuée au moyen d'une languette, non représentée, disposée en partie avant dudit bloc. Manipulation of the block 6 from its retracted position to its deployed position, and vice versa, can be effected by means of a tongue, not shown, arranged in front of said block.
Par ailleurs, le bloc 6 peut comprendre,un revêtement similaire à celui du coussin 4, ceci afin d'assurer une esthétique optimale du siège. Furthermore, the block 6 may comprise a coating similar to that of the cushion 4, this to ensure an optimal aesthetics of the seat.
