D'autres caractéristiques et avantages de l'invention apparaîtront à la lecture de la description d'exemples de réalisation d'une rehausse gonflable aux dessins annexés dans lesquels :Other characteristics and advantages of the invention will appear on reading the description of exemplary embodiments of an inflatable riser in the appended drawings in which:
- La figure 1 représente une vue perspective d'un siège équipé de la rehausse gonflable selon l'invention.- Figure 1 shows a perspective view of a seat equipped with the inflatable riser according to the invention.
- La figure 2 représente une section de l'assise d'un siège intégrant une rehausse gonflable selon l'invention.- Figure 2 shows a section of the seat of a seat incorporating an inflatable riser according to the invention.
- La figure 3 représente une vue perspective de la rehausse gonflable selon l'invention.- Figure 3 shows a perspective view of the inflatable riser according to the invention.
- La figure 4 représente une section transversale de la rehausse gonflable selon l'invention. La figure 1 représente un siège 1 constitué d'une assise 2 et d'un dossier 3 portés par un même élément de structure 4, qui forme un élément porteur dudit siège 1. La structure 4 est un élément peu déformable qui ne permet pas un déplacement en hauteur de l'assise 2, dans son ensemble. Deux ouvertures 6 et 7 sont réalisées afin de recevoir respectivement un élément d'assise 10 et un élément de dossier 40. La structure 4 est montée sur des glissières longitudinales 8 afin de régler la position du passager par rapport au volant, lorsqu'il s'agit par exemple du conducteur.- Figure 4 shows a cross section of the inflatable riser according to the invention. FIG. 1 represents a seat 1 consisting of a seat 2 and a backrest 3 carried by the same structural element 4, which forms a support element for said seat 1. The structure 4 is a slightly deformable element which does not allow a displacement in height of the seat 2, as a whole. Two openings 6 and 7 are made in order to respectively receive a seat element 10 and a backrest element 40. The structure 4 is mounted on longitudinal rails 8 in order to adjust the position of the passenger relative to the steering wheel, when s 'acts for example of the driver.
Tel que représenté à la figure 2, l'élément d'assise 10 est constitué d'une structure d'assise 11, réalisée par exemple par des lattes, pouvant avoir une déformation élastique, et qui forme la suspension dudit élément d'assise 10. La structure d'assise 11 porte un coussin 12, constitué par exemple d'une mousse, qui permet au passager d'obtenir un certain confort et une certaine souplesse, l'ensemble comportant un habillage extérieur. Le coussin 12 comporte sur son pourtour une rainure 13 recevant un rebord 14, de la structure 4 du siège 1, qui délimite 1 Ouverture 6. La coopération de la rainure 13 et du rebord 14 permet une retenue du coussin 12.As shown in FIG. 2, the seat element 10 consists of a seat structure 11, produced for example by slats, which may have an elastic deformation, and which forms the suspension of said seat element 10 The seat structure 11 carries a cushion 12, consisting for example of a foam, which allows the passenger to obtain a certain comfort and a certain flexibility, the assembly comprising an external covering. The cushion 12 has on its periphery a groove 13 receiving a rim 14, of the structure 4 of the seat 1, which delimits 1 Opening 6. The cooperation of the groove 13 and the rim 14 allows the cushion 12 to be retained.
La structure d'assise 11 est en contact avec un élément de fermeture 15 par l'intermédiaire d'un élément rehausseur 30, formé par une entretoise gonflage. L'élément de fermeture 15 peut être une plaque en tôle ou en matériaux composite, par exemple. Cet élément de fermeture 15 est fixé à la structure 4 du siège 1, afin d'obtenir un élément d'appui de l'entretoise gonflable 30. L'élément de fermeture 15 peut obturer le dessous de l'assise 2 de manière complète ou partielle. L'élément de fermeture peut également former un élément d'obturation de la partie arrière du dossier 3 du siège 1.The seat structure 11 is in contact with a closing element 15 by means of a booster element 30, formed by an inflation spacer. The closing element 15 can be a plate of sheet metal or of composite materials, for example. This closing element 15 is fixed to the structure 4 of the seat 1, in order to obtain a support element for the inflatable spacer 30. The closing element 15 can completely seal the underside of the seat 2 or partial. The closure element can also form a closure element for the rear part of the backrest 3 of the seat 1.
Tel que représenté à la figure 3, l'entretoise gonflable 30 à la forme générale d'un anneau creux, réalisé dans une matière souple, tel que par exemple de l'élastomère. L'anneau comporte des parois de compartimentations 31, qui forment des zones pouvant recevoir une pression différente, tel que représenté à la figure 4, chaque compartiment reçoit des parois longitudinales 32a et 32b qui définies trois chambres 33, 34 et 35 reliées entre elles par l'intermédiaire d'orifice de communication 36a et 36b. Ces orifices 36a et 36b sont de diamètre différent en fonction de leur proximité du centre de l'assise. A titre d'exemple, la paroi longitudinale 32a séparant la chambre intérieure 33 de la chambre médiane 34 reçoit un orifice 36a de communication ayant un diamètre de passage de l'air plus important que celui qui est réalisé dans la paroi longitudinale 32b séparant la chambre médiane 34 de la chambre extérieure 35. Cette communication permet de ralentir la diffusion de l'air entre les chambres et de limiter la sensation de flottement qui pourrait apparaître, en particulier lorsque la pression est faible.As shown in Figure 3, the inflatable spacer 30 has the general shape of a hollow ring, made of a flexible material, such as for example elastomer. The ring has compartment walls 31, which form zones capable of receiving a different pressure, as shown in FIG. 4, each compartment receives longitudinal walls 32a and 32b which define three chambers 33, 34 and 35 connected together by through communication port 36a and 36b. These holes 36a and 36b are of different diameter depending on their proximity to the center of the seat. By way of example, the longitudinal wall 32a separating the interior chamber 33 from the central chamber 34 receives a communication orifice 36a having a larger air passage diameter than that which is produced in the longitudinal wall 32b separating the chamber median 34 of the outer chamber 35. This communication makes it possible to slow the diffusion of air between the chambers and to limit the feeling of floating which could appear, in particular when the pressure is low.
L'ensemble des compartiments est relié à un compresseur d'air 20 par l'intermédiaire d'un répartiteur de pression 21. Il est possible d'utiliser également un fluide d'une viscosité plus élevée, en lieu et place de l'air. Des boutons de commande 22, localisés par exemple dans la structure 4 du siège 1, permettent de régler la pression des compartiments et par conséquent de rehausser ou d'abaisser le passager. Un capteur de déplacement 37 est positionné au centre de l'entretoise gonflable 30 afin de déterminer la course de la rehausse. Un tel capteur 37 permet de limiter le déplacement de la rehausse par la coupure du compresseur 20 lorsque la limite haute est atteinte. Le capteur 37 peut être asservi à des paramètres extérieurs à la rehausse, tel que la position du siège 1 dans les glissières. Le capteur 37 peut également asservir le réglage de l'élément de dossier 40 du siège 1, en particulier lors de l'inclinaison de l'assise, ou lors d'un ajustement en hauteur, dans ce cas l'élément de dossier 40 peut également être pourvu de moyens de coulissements en hauteur du coussin de dossier. En faisant varier la pression, en particulier dans les compartiments avant et arrière, il est possible de faire varier légèrement l'inclinaison de l'élément d'assise 10.All of the compartments are connected to an air compressor 20 via a pressure distributor 21. It is also possible to use a fluid of higher viscosity, instead of air. . Control buttons 22, located for example in the structure 4 of the seat 1, make it possible to adjust the pressure of the compartments and consequently to raise or lower the passenger. A sensor displacement 37 is positioned in the center of the inflatable spacer 30 in order to determine the stroke of the riser. Such a sensor 37 makes it possible to limit the displacement of the riser by switching off the compressor 20 when the upper limit is reached. The sensor 37 can be controlled by parameters external to the riser, such as the position of the seat 1 in the slides. The sensor 37 can also control the adjustment of the back element 40 of the seat 1, in particular during the inclination of the seat, or during an adjustment in height, in this case the back element 40 can also be provided with means for sliding the height of the back cushion. By varying the pressure, in particular in the front and rear compartments, it is possible to slightly vary the inclination of the seat element 10.
La structure de rehausse gonflable peut être également intégrée dans le dossier pour régler la profondeur ou faire varier la dureté de certaine zone, tel que par exemple un appui lombaire.The inflatable riser structure can also be integrated into the backrest to adjust the depth or vary the hardness of certain areas, such as for example a lumbar support.
Selon un second mode de réalisation, non représenté, l'entretoise gonflable 30 peut porter des moyens élastiques destinés à effectuer la suspension de la structure d'assise 11. Les moyens élastiques peuvent être localisés entre l'entretoise gonflable 30 et la structure d'assise 11, ou entre l'entretoise gonflable 30 et l'élément de fermeture 15. Dans le cas ou des moyens élastiques de suspension de l'assise sont intercalés entre l'entretoise gonflable 30 et l'élément de fermeture 15, ladite entretoise gonflable 30 peut comporter directement la structure d'assise 11 et les éléments du coussin d'assise 12. La structure d'assise 11 peut être formée d'une coque plastique plus ou moins rigide recouverte, par exemple de poche de gel, afin de créer l'aspect confort et souplesse. L'entretoise gonflable 30 peut également prendre la forme d'éléments rigides coulissants, selon une direction verticale, l'un par rapport à l'autre, afin de former l'équivalent d'un vérin. Avantageusement la partie supérieure pourra être intégré dans la structure d'assise 11.According to a second embodiment, not shown, the inflatable spacer 30 can carry elastic means intended to effect the suspension of the seat structure 11. The elastic means can be located between the inflatable spacer 30 and the structure of seat 11, or between the inflatable spacer 30 and the closing element 15. In the case where elastic means for suspending the seat are interposed between the inflatable spacer 30 and the closing element 15, said inflatable spacer 30 may directly comprise the seat structure 11 and the elements of the seat cushion 12. The seat structure 11 may be formed from a more or less rigid plastic shell covered, for example with a gel pocket, in order to create the comfort and flexibility aspect. The inflatable spacer 30 can also take the form of rigid sliding elements, in a vertical direction, relative to one another, in order to form the equivalent of a jack. Advantageously, the upper part can be integrated into the seat structure 11.
Selon un autre mode de réalisation, non représenté, l'entretoise gonflable 30 peut être formé d'un ensemble de vérins réglables orientés verticalement. La course de la rehausse étant réglée en fonction de la pression des vérins. Avantageusement les vérins peuvent intégrés des moyens de suspension. L'utilisation de vérins intégrants des moyens suspension, facilite le contrôle et la filtration de certaine fréquence par le pilotage de la raideur, par des moyens connus en soit, desdits moyens de suspension. According to another embodiment, not shown, the inflatable spacer 30 can be formed of a set of adjustable jacks oriented vertically. The stroke of the riser being adjusted according to the pressure of the cylinders. Advantageously, the jacks can incorporate suspension means. The use of jacks incorporating suspension means facilitates the control and filtration of a certain frequency by controlling the stiffness, by means known per se, of said suspension means.
