Description
L'invention concerne un dispositif pour le montage et l'accouplement deThe invention relates to a device for mounting and coupling of
sièges par rapport à une structure et trouve une application avantageuse dans le domaine technique des sièges pour véhicules automobiles. De plus en plus, les véhicules automobiles présentent des équipements pour participer efficacement à la sécurité active et/ou passive des passagers et du conducteur. seats relative to a structure and finds an advantageous application in the technical field of motor vehicle seats. Increasingly, motor vehicles present equipment to participate effectively in the active and / or passive safety of passengers and the driver.
10 C'est ainsi que l'on a proposé d'équiper les sièges de véhicules de systèmes anti-sousmarinage évitant au conducteur et aux passagers de glisser lors de collision frontale notamment. En effet, il est apparu que ce risque de sousmarinage est important et très dangereux en étant susceptible de provoquer des fractures au niveau des membres inférieurs, une coupure 15 de la carotide par la ceinture de sécurité, ... Thus, it has been proposed to equip the vehicle seats with anti-submarining systems which prevent the driver and passengers from slipping during a frontal collision in particular. Indeed, it has been found that this risk of submarining is important and very dangerous, being liable to cause fractures in the lower limbs, carotid disconnection by the safety belt, etc.
Différentes solutions ont été proposées pour réaliser un système d'anti-sousmarinage, par exemple sous forme d'une cuvette renversée réalisée dans le plancher du véhicule, et disposée sous la position 20 d'utilisation de l'assise. Le brevet FR 2 777 233 décrit un moyen anti-sousmarinage permettant la retenue sous cuisse de l'occupant en position d'utilisation de l'assise, lequel système anti-sousmarinage est conformé pour être escamotable lors du basculement de ladite assise. 25 Le brevet FR 2 868 997 décrit un siège pourvu d'une cuvette antisousmarinage escamotable permettant de basculer le dossier du siège en avant vers le plancher, sans être gêné par la cuvette anti-sousmarinage.5 On a proposé également d'équiper les véhicules de limiteur de force afin d'éviter les trop fortes pressions sur le thorax lors des collisions. Ces limiteurs ont pour effet de redonner du mou à la ceinture lorsque la pression est trop importante. Various solutions have been proposed for producing an anti-submarining system, for example in the form of an inverted cup made in the floor of the vehicle, and disposed under the position 20 of use of the seat. The patent FR 2,777,233 describes an anti-submarining means for retaining the thigh under the occupant position of use of the seat, which anti-submarining system is shaped to be retractable when tilting said seat. Patent FR 2 868 997 discloses a seat provided with a retractable anti-mousemoving bowl enabling the seat back to be tilted forward towards the floor, without being hampered by the anti-submarining basin. It has also been proposed to equip the vehicles. force limiter to prevent excessive pressure on the thorax during collisions. These limiters have the effect of giving slack to the belt when the pressure is too important.
Il est donc apparu très important de limiter l'impact aux chocs, aussi bien dans le cas d'une collision frontale, que dans le cas d'une collision arrière, et notamment de diminuer l'intensité des chocs encaissés par les sièges avant et/ou arrière, et directement transmis aux occupants des sièges. It therefore appeared very important to limit the impact to shocks, both in the case of a frontal collision, as in the case of a rear collision, and in particular to reduce the intensity of the shocks received by the front seats and / or rear, and directly transmitted to the occupants of the seats.
Le problème que se propose de résoudre l'invention est d'absorber les énergies de chocs non plus par l'intermédiaire des sièges, mais par l'intermédiaire de la caisse du véhicule, tout en gardant les fonctionnalités classiques d'un siège, notamment ses différentes capacités de réglage. 15 Pour résoudre ce problème, il a été conçu et mis au point un dispositif de montage d'un siège de véhicule automobile comprenant une assise équipée ou non d'un ensemble anti-sousmarinage et d'un dossier articulé. Ce dispositif comprend des moyens assujettis à l'assise et/ou au 20 dossier coopérant, avec capacité de déplacement, avec des agencements de la caisse du véhicule pour assurer une reprise des efforts et permettre, en cas de chocs, une absorption de l'énergie par ladite caisse. The problem to be solved by the invention is to absorb shock energy not via the seats, but through the vehicle body, while keeping the conventional features of a seat, including its different adjustment capabilities. To solve this problem, it has been designed and developed a device for mounting a motor vehicle seat comprising a seat with or without an anti-submarining assembly and an articulated backrest. This device comprises means subject to the seat and / or backrest cooperating, with displacement capacity, with arrangements of the vehicle body to ensure recovery of efforts and allow, in case of shocks, absorption of the energy by said box.
Pour résoudre le problème posé d'absorber l'énergie des chocs par 25 l'intermédiaire de la caisse du véhicule, les moyens sont constitués par des éléments tubulaires traversant une partie de l'assise et/ou du dossier. Les agencements sont constitués par des rails fixés à la caisse du véhicule 10 permettant le coulissement longitudinal du siège et l'accouplement des éléments tubulaires avec capacité de coulissement. To solve the problem posed of absorbing shock energy through the vehicle body, the means consist of tubular elements passing through part of the seat and / or the backrest. The arrangements are constituted by rails fixed to the vehicle body 10 allowing the longitudinal sliding of the seat and the coupling of the tubular elements with sliding capacity.
A partir de cette conception de base, différentes formes de réalisation peuvent être envisagées : l'un des éléments tubulaires est disposé à l'arrière et à la base de l'assise ; l'un des éléments tubulaires est disposé sensiblement au 3/4 de la hauteur du dossier à la hauteur d'absorption, ledit élément tubulaire permettant le coulissement longitudinal du dossier ; un même élément tubulaire ou deux éléments tubulaires distincts traverse(nt) les assises et/ou les dossiers de deux sièges séparés. From this basic design, various embodiments can be envisaged: one of the tubular elements is disposed at the rear and at the base of the seat; one of the tubular elements is disposed substantially at 3/4 of the height of the backrest at the absorption height, said tubular element allowing the longitudinal sliding of the backrest; the same tubular element or two distinct tubular elements cross (s) the seats and / or the backs of two separate seats.
Compte tenu de ces caractéristiques, il est possible de réduire le poids des sièges. Dans ce but, en dessous de l'élément tubulaire traversant le dossier, est formée une découpe permettant de réduire l'épaisseur dudit dossier. Given these characteristics, it is possible to reduce the weight of the seats. For this purpose, below the tubular element through the backrest is formed a cut to reduce the thickness of said folder.
Dans une autre forme de réalisation et notamment pour les sièges disposés à l'arrière du véhicule, c'est-à-dire à proximité du compartiment bagages, le dispositif comprend au moins un élément tubulaire indépendant rendu solidaire, d'une manière fixe, des rails, en arrière de l'assise et en dehors de cette dernière, sensiblement au droit du dossier. In another embodiment and in particular for the seats arranged at the rear of the vehicle, that is to say in the vicinity of the luggage compartment, the device comprises at least one independent tubular element secured in a fixed manner, rails, behind the seat and outside the latter, substantially to the right of the folder.
L'invention s'applique pour différents types de sièges, y compris lorsque le dossier et l'assise sont liés par l'intermédiaire d'une articulation ou lorsque le dossier et l'assise sont indépendants. Le dispositif peut être appliqué pour les sièges avant et/ou arrière du véhicule. The invention applies to different types of seats, including when the backrest and the seat are connected via a joint or when the backrest and seat are independent. The device can be applied for the front and / or rear seats of the vehicle.
L'invention est exposée ci-après plus en détail à l'aide des figures des dessins annexés dans lesquels : - la figure 1 est une vue en coupe à caractère schématique d'un siège de véhicule équipé du dispositif selon l'invention ; - la figure 2 est une vue de face correspondant à la figure 1 - la figure 3 montre une autre forme de réalisation du dispositif, notamment dans le cas d'un siège arrière, le dossier qui est articulé à l'assise présentant un évidement afin de diminuer le poids ; - la figure 4 est une vue semblable à la figure 3, dans le cas où le dossier est articulé d'une manière séparée de l'assise. The invention is described below in more detail with the help of the figures of the accompanying drawings in which: - Figure 1 is a schematic sectional view of a vehicle seat equipped with the device according to the invention; - Figure 2 is a front view corresponding to Figure 1 - Figure 3 shows another embodiment of the device, especially in the case of a rear seat, the backrest which is articulated to the seat having a recess to to reduce the weight; - Figure 4 is a view similar to Figure 3, in the case where the backrest is articulated separately from the seat.
Comme indiqué, l'invention s'applique pour le montage de tout type de siège, et trouve une application avantageuse dans le cas de sièges de véhicules automobiles. On rappelle, d'une manière parfaitement connue, qu'un siège comprend une assise (1) et un dossier (2), généralement articulés en (3) au niveau de ladite assise. L'assise (1) peut ou non être équipée d'un ensemble anti-sousmarinage (7) de tout type connu et approprié pour un homme du métier. As indicated, the invention applies to the assembly of any type of seat, and finds an advantageous application in the case of motor vehicle seats. It is recalled, in a perfectly known manner, that a seat comprises a seat (1) and a backrest (2), generally articulated at (3) at said seat. The seat (1) may or may not be equipped with an anti-submarining assembly (7) of any type known and suitable for a skilled person.
Comme indiqué, le but recherché selon l'invention est de permettre, lors de chocs, une absorption des énergies par la caisse du véhicule et non plus seulement au niveau de la structure du siège en tant que tel. Dans ce but, le dispositif comprend des éléments tubulaires coopérant avec un système de rails (5) et (6) permettant le déplacement longitudinal du siège considéré, et fixés à l'intérieur du véhicule sur une partie de la caisse. Ainsi, le rail (6) est disposé au niveau sensiblement du plancher du véhicule, où est montée l'assiste (1), tandis que le rail (5) est disposé sensiblement au 3/4 de la hauteur du dossier du siège considéré et correspondant à la hauteur d'absorption des efforts. As indicated, the purpose of the invention is to allow, during shocks, absorption of energy by the vehicle body and not only at the seat structure as such. For this purpose, the device comprises tubular elements cooperating with a system of rails (5) and (6) for the longitudinal displacement of the seat considered, and fixed inside the vehicle on a part of the body. Thus, the rail (6) is disposed at substantially the floor of the vehicle, which is mounted assists (1), while the rail (5) is disposed substantially at 3/4 of the height of the seat back and considered corresponding to the absorption height of the forces.
L'un des éléments tubulaires (4) peut être disposé à l'arrière et à la base de l'assise (figures 1 et 3), tandis qu'un autre élément tubulaire (4a) est disposé au niveau de la partie avant de l'assise, par exemple en combinaison avec le système anti-sousmarinage (7). One of the tubular elements (4) can be arranged at the rear and at the base of the seat (Figures 1 and 3), while another tubular element (4a) is disposed at the front portion of the seat. the seat, for example in combination with the anti-submarining system (7).
Un autre élément tubulaire (4b) est disposé sensiblement au 3/4 de la hauteur du dossier et coopère avec capacité de coulissement avec le rail supérieur (5) pour permettre le coulissement du dossier en longitudinal. Les éléments tubulaires (4a) et (4b) coopèrent, avec capacité de coulissement, avec le rail inférieur (6) pour le déplacement longitudinal de l'ensemble du siège. Another tubular element (4b) is disposed substantially at 3/4 of the height of the backrest and cooperates with sliding capacity with the upper rail (5) to allow the longitudinal sliding of the backrest. The tubular elements (4a) and (4b) cooperate, with sliding capacity, with the lower rail (6) for the longitudinal displacement of the entire seat.
Dans le cas de deux sièges juxtaposés (avant ou arrière), un même élément tubulaire traverse les dossiers et les assises des deux sièges, ou bien il est possible d'utiliser des tubes distincts et indépendants pour le dossier et l'assise. Il est également possible d'utiliser un seul tube commun pour relier les deux assises des deux sièges séparés et un tube distinct pour chacun des dossiers (figure 2). In the case of two juxtaposed seats (front or rear), the same tubular element crosses the backs and seats of the two seats, or it is possible to use separate and independent tubes for the backrest and the seat. It is also possible to use a single common tube to connect the two seats of the two separate seats and a separate tube for each of the folders (Figure 2).
A noter que l'élément tubulaire (4), disposé à l'arrière de l'assise (1), s'avère particulièrement efficace pour absorber les chocs susceptibles de résulter des bagages. Dans ce but, et comme le montrent notamment les figures 3 et 4, le dispositif selon l'invention peut également comprendre au moins un élément tubulaire indépendant (8) rendu solidaire, d'une manière fixe, des rails inférieurs (6), à l'arrière de l'assise (1) et en dehors de cette dernière. L'élément tubulaire (8) est disposé sensiblement au droit du dossier (2). Note that the tubular element (4), disposed at the rear of the seat (1), is particularly effective in absorbing the shocks that may result from luggage. For this purpose, and as shown in particular in FIGS. 3 and 4, the device according to the invention may also comprise at least one independent tubular element (8) secured, in a fixed manner, to the lower rails (6), to the back of the seat (1) and outside the latter. The tubular element (8) is arranged substantially to the right of the backrest (2).
Selon l'invention, compte tenu de la reprise des efforts par les différents éléments tubulaires, au niveau de la caisse du véhicule, il est possible de diminuer par exemple l'épaisseur du dossier pour gagner du poids. Les figures 3 et 4 montrent une découpe (2a) formée dans l'épaisseur du dossier (2) sous l'élément tubulaire de reprise (4b). According to the invention, taking into account the recovery efforts by the various tubular elements at the vehicle body, it is possible to reduce for example the thickness of the record to save weight. Figures 3 and 4 show a cutout (2a) formed in the thickness of the backrest (2) under the tubular recovery member (4b).
Le dispositif selon l'invention s'applique aussi bien dans le cas où le dossier et l'assise sont liés par l'intermédiaire d'une articulation (3) (figure 3), que dans le cas où le dossier et l'assise sont indépendants, le dossier (2) étant articulé en (9), d'une manière indépendante de ladite assise. The device according to the invention applies equally well in the case where the backrest and the seat are connected by means of a hinge (3) (FIG. 3), only in the case where the backrest and the seat are independent, the backrest (2) being hinged in (9), independently of said seat.
L'invention s'applique aussi bien pour les sièges avant et/ou arrière d'un véhicule, sans pour cela exclure d'autres applications. The invention applies equally well to the front and / or rear seats of a vehicle, without thereby excluding other applications.
Les avantages ressortent bien de la description. The advantages are apparent from the description.
