Structure de siège à coulissement transversal, pour véhicule automobile.  Cross-slide seat structure for a motor vehicle.

La présente invention concerne une structure de siège à coulissement latéral pour véhicule automobile, présentant une 5 résistance accrue en cas de choc.  The present invention relates to a lateral sliding seat structure for a motor vehicle, having increased resistance in the event of impact.

On connaît des véhicules automobiles équipés de sièges pouvant être déplacés latéralement, c'est-à-dire transversalement à l'axe longitudinal du véhicule.  Motor vehicles are known with seats that can be moved laterally, that is to say transversely to the longitudinal axis of the vehicle.

La structure de ces sièges comprend un support mobile supportant l'assise du siège et un support fixe relié au plancher du véhicule, le support mobile étant relié au support fixe par des moyens permettant au support mobile de coulisser par rapport au support fixe, transversalement par rapport à l'axe longitudinal du véhicule.  The structure of these seats comprises a mobile support supporting the seat of the seat and a fixed support connected to the floor of the vehicle, the movable support being connected to the fixed support by means allowing the movable support to slide relative to the fixed support, transversely by relative to the longitudinal axis of the vehicle.

En cas de choc du véhicule, les efforts sont entièrement supportés par les moyens de coulissement qui relient le support mobile au support fixe. Or, ces moyens de coulissement sont fragiles, de sorte que le siège risque d'être arraché du support fixe en cas de choc, ce qui risque de blesser gravement voire d'entraîner la mort de l'occupant du siège.  In case of impact of the vehicle, the forces are fully supported by the sliding means which connect the mobile support to the fixed support. However, these sliding means are fragile, so that the seat may be torn from the fixed support in case of shock, which may seriously injure or even cause death of the occupant of the seat.

Le but de la présente invention est de remédier à cet inconvénient en créant une structure de siège à coulissement latéral présentant une structure ayant une résistance nettement accrue en cas de choc du véhicule.  The object of the present invention is to overcome this disadvantage by creating a side sliding seat structure having a structure having a significantly increased resistance in case of impact of the vehicle.

L'invention vise ainsi une structure de siège pour véhicule comprenant un support mobile supportant l'assise du siège et un support fixe relié au plancher du véhicule, le support mobile étant relié au support fixe par des moyens permettant au support mobile de coulisser par rapport au support fixe, transversalement par rapport à l'axe longitudinal du véhicule.  The invention thus aims at a vehicle seat structure comprising a movable support supporting the seat cushion and a fixed support connected to the floor of the vehicle, the movable support being connected to the fixed support by means allowing the movable support to slide relative to at the fixed support, transversely to the longitudinal axis of the vehicle.

Suivant l'invention, cette structure de siège est caractérisée en ce que le support mobile comporte en outre, sur sa face inférieure et près du bord avant et du bord arrière de celle-ci, des moyens venant en prise avec des moyens complémentaires prévus à l'avant et à l'arrière de la face supérieure du support fixe, ces moyens permettant le coulissement transversal précité, tout en renforçant la résistance de la structure en cas de choc.  According to the invention, this seat structure is characterized in that the movable support further comprises, on its lower face and near the front edge and the rear edge thereof, means engaging with complementary means provided for in FIG. the front and rear of the upper face of the fixed support, these means allowing the aforementioned transverse sliding, while strengthening the strength of the structure in case of impact.

Les moyens précités prévus sur le support mobile, qui coopèrent avec les moyens complémentaires du support fixe, prennent en compte la quasitotalité des efforts engendrés en cas de choc, en préservant ainsi les moyens de coulissement qui sont normalement prévus entre le support mobile du siège et le support fixe.  The aforementioned means provided on the mobile support, which cooperate with the complementary means of the fixed support, take into account the quasi-totality of the forces generated in the event of impact, thus preserving the sliding means which are normally provided between the mobile support of the seat and the fixed support.

Selon une réalisation avantageuse de l'invention, la structure du siège comprend, d'une part, des moyens solidaires du support mobile présentant deux gorges de section en U dont l'une, près du bord avant de la face inférieure du support mobile, est ouverte vers l'arrière de ce support et dont l'autre, près du bord arrière de cette face inférieure, est ouverte vers l'avant du support, et d'autre part, des moyens solidaires du support fixe présentant deux parties en saillie qui sont engagées avec jeu dans les gorges en U du support mobile.  According to an advantageous embodiment of the invention, the seat structure comprises, on the one hand, means secured to the movable support having two U-section grooves, one of which, near the front edge of the lower face of the movable support, is open towards the rear of this support and the other, near the rear edge of this lower face, is open towards the front of the support, and secondly, means secured to the fixed support having two projecting parts. which are engaged with play in the U-shaped grooves of the movable support.

Les parties en saillie du support fixe engagées dans les gorges du support mobile encaissent ainsi les efforts engendrés en cas de choc.  The projecting parts of the fixed support engaged in the grooves of the movable support thus absorb the forces generated in case of impact.

Dans une réalisation préférée de l'invention, lesdits moyens et moyens complémentaires sont réalisés d'une seule pièce avec le support mobile et avec le support fixe.  In a preferred embodiment of the invention, said means and complementary means are made in one piece with the mobile support and with the fixed support.

Cette réalisation d'une seule pièce permet d'obtenir une structure compacte et résistante.  This one-piece construction provides a compact and durable structure.

De préférence, le support fixe et le support mobile sont moulés en alliage léger à base d'aluminium ou de magnésium.  Preferably, the fixed support and the movable support are molded in light alloy based on aluminum or magnesium.

Dans un mode de réalisation, la face inférieure du support mobile comporte deux gorges parallèles à l'axe transversal de coulissement du siège et la face supérieure du support fixe comporte deux nervures engagées dans les deux gorges du support mobile, des moyens de réduction du frottement étant disposés entre les nervures et les gorges.  In one embodiment, the lower face of the movable support comprises two grooves parallel to the transverse axis of sliding of the seat and the upper face of the fixed support has two ribs engaged in the two grooves of the mobile support, means for reducing friction. being arranged between the ribs and the grooves.

Dans ce mode de réalisation, les deux gorges et les deux nervures engagées dans celles-ci servent uniquement à guider le coulissement du support mobile par rapport au support fixe et n'encaissent aucun effort en cas de choc.  In this embodiment, the two grooves and the two ribs engaged in them serve only to guide the sliding of the movable support relative to the fixed support and do not incur any effort in case of impact.

D'autres particularités et avantages de l'invention apparaîtront encore dans la description ci-après.  Other features and advantages of the invention will become apparent in the description below.

Aux dessins annexés, donnés à titre d'exemples non limitatifs: -la figure 1 est une vue en élévation latérale d'un siège présentant une structure selon l'invention, 2886227 3 - la figure 2 est une vue à échelle agrandie du détail A de la figure 1, - la figure 3 est une vue analogue à la figure 1 concernant une variante de la structure selon l'invention, - la figure 4 est une vue à échelle agrandie du détail B de la figure 3.  In the accompanying drawings, given by way of non-limiting examples: FIG. 1 is a side elevational view of a seat having a structure according to the invention, FIG. 2 is an enlarged view of detail A FIG. 3 is a view similar to FIG. 1 relating to a variant of the structure according to the invention, FIG. 4 is an enlarged view of detail B of FIG. 3.

Dans les réalisations représentées sur les figures annexées, la structure de siège pour véhicule automobile, comprend un support mobile 1 supportant l'assise 2 du siège et un support fixe 3 relié au plancher 4 du véhicule.  In the embodiments shown in the accompanying figures, the seat structure for a motor vehicle comprises a movable support 1 supporting the seat 2 of the seat and a fixed support 3 connected to the floor 4 of the vehicle.

Le support mobile 1 est relié au support fixe 3 par des moyens (qui seront détaillés plus loin) permettant au support mobile 1 de coulisser par rapport au support fixe 3, transversalement par rapport à l'axe longitudinal L du véhicule.  The mobile support 1 is connected to the fixed support 3 by means (which will be detailed later) allowing the mobile support 1 to slide relative to the fixed support 3, transversely to the longitudinal axis L of the vehicle.

Selon l'invention, le support mobile 1 comporte en outre, sur sa face inférieure la et près du bord avant 5 et du bord arrière 6 de celle-ci, des moyens venant en prise avec des moyens complémentaires prévus à l'avant 7 et à l'arrière 8 de la face supérieure 3a du support fixe 3. Ces moyens permettent, comme il sera expliqué plus loin, le coulissement transversal précité, tout en renforçant la résistance de la structure en cas de choc du véhicule.  According to the invention, the mobile support 1 further comprises, on its lower face and near the front edge 5 and the rear edge 6 of the latter, means engaging with complementary means provided in the front 7 and at the rear 8 of the upper face 3a of the fixed support 3. These means allow, as will be explained later, the aforementioned transverse sliding, while strengthening the strength of the structure in case of impact of the vehicle.

Comme montré par les figures 1 et 2, la structure selon l'invention comprend, d'une part, des moyens solidaires du support mobile 1 présentant deux gorges 9, 10 de section en U dont l'une 9, près du bord avant 5 de la face inférieure la du support mobile 1, est ouverte vers l'arrière de ce support et dont l'autre 10, près du bord arrière 6 de cette face inférieure la, est ouverte vers l'avant du support 1.  As shown in FIGS. 1 and 2, the structure according to the invention comprises, on the one hand, means integral with the mobile support 1 having two grooves 9, 10 of U section, one of which 9, near the front edge 5 of the lower face of the mobile support 1, is open towards the rear of this support and the other 10, near the rear edge 6 of this lower face, is open towards the front of the support 1.

La structure comprend d'autre part, des moyens solidaires du support fixe 3 présentant deux parties en saillie 11, 12 qui sont engagées avec jeu dans les gorges en U 9, 10 du support mobile 1.  The structure further comprises means secured to the fixed support 3 having two projecting parts 11, 12 which are engaged with play in the U-shaped grooves 9, 10 of the mobile support 1.

L'engagement avec jeu des parties en saillie 11, 12 dans les gorges 9, 10 permet de réduire les frottements lors du coulissement du siège transversalement à la direction L. Dans une version préférée de l'invention, les moyens et moyens complémentaires précités sont réalisés d'une seule pièce avec le support mobile 1 et avec le support fixe 3, comme montré sur la figure 1.  The engagement with play of the projecting parts 11, 12 in the grooves 9, 10 makes it possible to reduce the friction during the sliding of the seat transversely to the direction L. In a preferred version of the invention, the complementary means and means mentioned above are made in one piece with the mobile support 1 and with the fixed support 3, as shown in Figure 1.

De préférence également, le support fixe 3 et le support mobile 1 sont moulés en alliage léger à base d'aluminium ou de magnésium, ce qui permet d'obtenir une structure légère et résistante.  Also preferably, the fixed support 3 and the mobile support 1 are molded of light alloy based on aluminum or magnesium, which allows to obtain a light and resistant structure.

Dans la version représentée sur la figure 1, la face inférieure la du support mobile 1 comporte en outre deux gorges 13, 14 parallèles à l'axe transversal de coulissement du siège et la face supérieure 3a du support fixe 3 comporte deux nervures 15, 16 engagées dans les deux gorges 13, 14 du support mobile 1. Des moyens de réduction du frottement, par exemple des billes 17, sont disposés entre les nervures 15, 16 et les gorges 13, 14, comme montré sur la figure 2.  In the version shown in Figure 1, the lower face of the movable support 1 further comprises two grooves 13, 14 parallel to the transverse axis of sliding of the seat and the upper face 3a of the fixed support 3 comprises two ribs 15, 16 engaged in the two grooves 13, 14 of the mobile support 1. Friction reduction means, for example balls 17, are arranged between the ribs 15, 16 and the grooves 13, 14, as shown in Figure 2.

Dans la variante représentée sur la figure 3, la face inférieure la du support mobile 1 porte un premier plateau 18 dont les bords avant et arrière sont repliés pour former deux gorges en U 9, 10. La gorge avant 9 s'ouvre vers l'arrière et la gorge arrière 10 s'ouvre vers l'avant.  In the variant shown in Figure 3, the lower face of the movable support 1 carries a first plate 18, the front and rear edges are folded to form two U-shaped grooves 9, 10. The front groove 9 opens towards the rear and the rear groove 10 opens to the front.

La face supérieure 3a du support fixe 3 porte un second plateau 19 dont les bords avant 11 et arrière 12 sont engagés avec jeu dans les gorges 9, 10 respectives du premier plateau 18.  The upper face 3a of the fixed support 3 carries a second plate 19 whose front edges 11 and rear 12 are engaged playfully in the respective grooves 9, 10 of the first plate 18.

Par ailleurs, les deux plateaux 18, 19 sont reliés l'un à l'autre par deux systèmes de glissière 20, 21 à coefficient de frottement réduit, permettant un coulissement du support mobile 1 par rapport au support fixe 3 transversalement par rapport à l'axe longitudinal L du véhicule.  Furthermore, the two plates 18, 19 are connected to one another by two slide systems 20, 21 with a reduced coefficient of friction, allowing the mobile support 1 to slide relative to the fixed support 3 transversely with respect to the longitudinal axis L of the vehicle.

L'un 20 des systèmes de glissière est représenté en détail sur la figure 4. Il comprend une première glissière 22 solidaire du plateau supérieur 18 engagée dans une seconde glissière 23 solidaire du plateau inférieur 19. Entre les deux glissières 22, 23, sont disposées des billes 24 permettant de réduire les frottements.  One of the slideway systems is shown in detail in FIG. 4. It comprises a first slideway 22 integral with the upper plate 18 engaged in a second slideway 23 secured to the lower plate 19. Between the two slideways 22, 23, are arranged balls 24 to reduce friction.

En cas de choc du véhicule, les liaisons mécaniques constituées par des gorges 9, 10 prévues à l'arrière et à l'avant du support mobile 1, dans lesquelles sont engagées des nervures 11, 12 du support fixe, prennent en compte la quasi-totalité des efforts, en évitant ainsi tout risque de basculement du siège occasionné par la destruction des glissières reliant la partie mobile du siège à la partie fixe solidaire du plancher du véhicule.  In case of impact of the vehicle, the mechanical links constituted by grooves 9, 10 provided at the rear and front of the mobile support 1, in which are engaged ribs 11, 12 of the fixed support, take into account the quasi -total efforts, thus avoiding any risk of tilting of the seat caused by the destruction of the rails connecting the mobile part of the seat to the fixed part of the vehicle floor.

La réalisation préférée de l'invention est celle représentée sur la figure 1 car les moyens de retenue et les moyens de coulissement sont réalisés d'une seule pièce, dans les supports mobile 1 et fixe 3, qui sont moulés en alliage léger, ce qui garantit une excellente résistance au choc et simplifie la construction.  The preferred embodiment of the invention is that shown in FIG. 1 because the retaining means and the sliding means are made in one piece, in the movable supports 1 and fixed 3, which are molded in light alloy, which guarantees excellent impact resistance and simplifies construction.
