Definitions
- the invention relates to a riser for a motor vehicle seat and more particularly to a riser for a thin seat.
- the invention relates to an inflatable riser which can be easily integrated into a thin seat.
- the invention also relates to an inflatable riser for moving a person seated on a one-piece seat.
- the seat comprises a booster element of a seat element, said booster element being located between a seat cushion and a closure element of said seat.
- the booster element is an inflatable spacer.
- the inflatable spacer has the general shape of a hollow ring.
- the inflatable spacer is ⁇ compartmentalized by transverse partitions.
- the inflatable spacer is compartmentalized by longitudinal partitions.
- the longitudinal partitions communicate with each other by means of at least one communication orifice and the diameter of which differs according to their proximity to the center of the seat.
- the inflatable spacer is interposed between a seat structure and the closure element.
- the booster element is formed by jacks.
- the booster element comprises means for suspending the seat element.
- the booster element comprises at least one means for controlling the stiffness of the suspension of the seat.
- the seat comprises a sensor for displacement of the seat element relative to the structure of the seat.
- the adjustment of the riser is a function of the position of the seat in longitudinal slides carrying said seat.
- FIG. 1 shows a perspective view of a seat equipped with the inflatable riser according to the invention.
- FIG. 2 shows a section of the seat of a seat incorporating an inflatable riser according to the invention.
- FIG. 3 shows a perspective view 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.
- 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.
- 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.
- 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.
- 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.
- 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.
- the pressure in particular in the front and rear compartments, it is possible to slightly vary the inclination of the seat element 10.
- 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.
- 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.
- 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.
- the upper part can be integrated into the seat structure 11.
- 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.
- 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.
