Description
<Desc/Clms Page number 1> <Desc / Clms Page number 1>
La présente invention se rapporte à un siège, plus particulièrement un siège de véhicule, dont l'assise est munie d'une partie centrale qui est réglable en hauteur. The present invention relates to a seat, more particularly a vehicle seat, the seat of which is provided with a central part which is adjustable in height.
Certains types de sièges, notamment des sièges de véhicules automobiles, sont munis de retenues latérales, disposées de part et d'autre de l'assise du siège, qui sont surélevés par rapport au plan du coussin. Certain types of seats, in particular seats of motor vehicles, are provided with lateral restraints, arranged on either side of the seat cushion, which are raised relative to the plane of the cushion.
Lorsqu'une personne âgée ou de mobilité réduite cherche à descendre d'une voiture elle peut rencontrer quelques difficultés, quand elle se tourne vers la porte de la voiture, à soulever ses jambes pour les passer au-dessus de la retenue latérale du côté de la porte. When an elderly person or person with reduced mobility seeks to get out of a car, he may encounter some difficulties, when he turns towards the door of the car, in raising his legs to pass them over the lateral restraint on the side of the door.
Il a déjà été proposé d'équiper le siège du véhicule afin qu'il puisse pivoter autour d'un axe vertical, afin de se trouver face à la porte de la voiture, facilitant ainsi la descente du passager. Cependant, ce type de siège, en plus d'un support pivotant, nécessite un système de loquet pour retenir le siège dans sa position face à la route. Cette construction rend le siège très coûteux. It has already been proposed to equip the vehicle seat so that it can pivot around a vertical axis, so as to be facing the door of the car, thus facilitating the descent of the passenger. However, this type of seat, in addition to a swivel support, requires a latch system to hold the seat in its position facing the road. This construction makes the seat very expensive.
Il a également été proposé de munir le siège de retenues latérales déplaçables. Par exemple, le document US 5 290 084 décrit un siège de véhicule dont les retenues latérales sont agencées pour pouvoir pivoter par rapport au siège entre une position basse facilitant l'accès d'une personne, et une position haute maintenant le passager entre les retenues latérales. Ce type de siège présente des inconvénients car les retenues latérales pivotant rend le siège large et encombrant. It has also been proposed to provide the seat with movable lateral restraints. For example, document US Pat. side. This type of seat has drawbacks because the pivoting lateral retainers make the seat wide and bulky.
La demanderesse s'est fixé pour objectifs de surmonter les difficultés et inconvénients rappelés ci-dessus ainsi que ceux rencontrés dans l'art antérieur en proposant un siège de véhicule de construction simple, peu encombrant et qui permet à une personne âgée ou de mobilité réduite de pouvoir s'y installer facilement. The Applicant has set itself the objectives of overcoming the difficulties and disadvantages mentioned above as well as those encountered in the prior art by proposing a vehicle seat of simple construction, compact and which allows an elderly person or of reduced mobility. to be able to settle there easily.
Aussi, la présente invention a trait à un siège comprenant une assise formée d'une partie centrale s'étendant dans un plan sensiblement horizontal et des retenues latérales, caractérisé en ce que la partie Also, the present invention relates to a seat comprising a seat formed by a central part extending in a substantially horizontal plane and lateral restraints, characterized in that the part
<Desc/Clms Page number 2><Desc / Clms Page number 2>
centrale est agencée pour être déplacée sensiblement verticalement par rapport au plan horizontal. central is arranged to be moved substantially vertically relative to the horizontal plane.
Avantageusement, la partie centrale est montée dans le siège au moyen d'un système de vis-écrou afin qu'une rotation de la partie centrale en entraîne un déplacement hélicoïdal de celle-ci par rapport au plan horizontal. Advantageously, the central part is mounted in the seat by means of a screw-nut system so that a rotation of the central part results in a helical displacement of the latter relative to the horizontal plane.
De préférence, la partie centrale est sensiblement circulaire, l'ensemble vis-écrou étant monté à son centre. Preferably, the central part is substantially circular, the screw-nut assembly being mounted at its center.
De manière alternative, la partie centrale est montée dans le siège au moyen d'un système de vis-écrou qui est agencé pour qu'une rotation d'un élément du système entraîne un déplacement vertical de la partie centrale par rapport au plan horizontal. Alternatively, the central part is mounted in the seat by means of a screw-nut system which is arranged so that a rotation of an element of the system causes the central part to move vertically relative to the horizontal plane.
D'autres caractéristiques et avantages de la présente invention vont maintenant être décrits de manière plus détaillée à l'aide des dessins annexés donnés à titre illustratif et non limitatif et dans lesquels, la Figure 1 représente, en vue de côté schématique, un siège équipé d'un coussin réglable en hauteur, selon l'invention ; la Figure 2 est une vue analogue à celle de la Figure 1, le coussin étant en sa position haute ; et la Figure 3 est une vue section, prise selon la ligne lil-lil de la Figure 1, de la partie centrale du siège. Other characteristics and advantages of the present invention will now be described in more detail with the aid of the appended drawings given by way of illustration and not limitation and in which, Figure 1 shows, in schematic side view, a seat equipped a height-adjustable cushion according to the invention; Figure 2 is a view similar to that of Figure 1, the cushion being in its high position; and Figure 3 is a sectional view, taken along the line lil-lil of Figure 1, of the central part of the seat.
Un siège, qui dans l'exemple illustré, est un siège de véhicule, représenté généralement en 10, comprend une assise 12 qui s'étend sensiblement dans un plan horizontal. L'assise 12 est délimitée par des retenues latérales 14 et 16, sensiblement symétriques, qui s'étendent verticalement au-delà du plan horizontal de l'assise 12. Le siège comprend de plus un dossier 18
Selon l'invention, l'assise 12 du siège 10 comprend une partie centrale 20 qui est agencée pour être déplacée sensiblement verticalement par rapport au plan horizontal de l'assise. La partie A seat, which in the example illustrated, is a vehicle seat, generally represented at 10, comprises a seat 12 which extends substantially in a horizontal plane. The seat 12 is delimited by lateral retainers 14 and 16, substantially symmetrical, which extend vertically beyond the horizontal plane of the seat 12. The seat further comprises a back 18
According to the invention, the seat 12 of the seat 10 comprises a central part 20 which is arranged to be moved substantially vertically relative to the horizontal plane of the seat. The part
<Desc/Clms Page number 3><Desc / Clms Page number 3>
centrale 20 est circulaire et son diamètre correspond à l'écartement entre les deux retenues 14 et16. central 20 is circular and its diameter corresponds to the spacing between the two retains 14 and 16.
La Figure 3 est une vue section, prise selon la ligne lil-lil de la Figure 1, de l'assise 12 du siège 10. Comme représentée sur cette figure, la partie centrale 20 comprend un support circulaire 22 muni d'un tube central taraudé 24 qui s'étend verticalement à partir du centre du support 22. Le tube est monté vissé sur un support vertical fileté (non-représenté) qui est solidaire du structure du siège 10. L'inclinaison du filet compris dans le tube 24 est tel qu'une faible rotation de la partie centrale résulte en un déplacement vertical important de la partie centrale. Ainsi, pour une rotation d'environ 900 de la partie centrale 20 du siège 10 provoquée par un passager du véhicule, la partie centrale se soulèvera jusqu'à une hauteur au moins équivalente à celle des retenues latérales 14 et 16, comme représentée sur la figure 2. Cette position permet une sortie aisée du passager. Figure 3 is a sectional view, taken along the line lil-lil of Figure 1, of the seat 12 of the seat 10. As shown in this figure, the central part 20 comprises a circular support 22 provided with a central tube threaded 24 which extends vertically from the center of the support 22. The tube is screwed onto a vertical threaded support (not shown) which is integral with the structure of the seat 10. The inclination of the thread included in the tube 24 is such that a slight rotation of the central part results in a significant vertical displacement of the central part. Thus, for a rotation of approximately 900 of the central part 20 of the seat 10 caused by a passenger of the vehicle, the central part will be raised to a height at least equivalent to that of the lateral retainers 14 and 16, as shown in the figure 2. This position allows an easy exit of the passenger.
Afin qu'une personne âgée ou de mobilité réduite puisse se retourner facilement sur le siège, il est envisagé que la partie centrale soit équipée d'un ressort de rappel ou de tout autre moyen d'assistance. So that an elderly person or person with reduced mobility can easily turn around on the seat, it is envisaged that the central part is equipped with a return spring or any other assistance means.
Selon une variante de l'invention qui n'est pas illustrée, il est envisagé que la partie centrale soit montée dans le siège au moyen d'un système de vis-écrou qui est agencé pour qu'une rotation d'un élément du système entraîne un déplacement vertical de la partie centrale par rapport au plan horizontal. De préférence, cet élément est mis en rotation sélectivement au moyen d'un moteur électrique. According to a variant of the invention which is not illustrated, it is envisaged that the central part is mounted in the seat by means of a screw-nut system which is arranged so that a rotation of an element of the system causes a vertical displacement of the central part relative to the horizontal plane. Preferably, this element is selectively rotated by means of an electric motor.
