  • the present invention relates to a seat accessory, intended in particular to constitute a trim to be placed at the level of the backrest and / or the seat, which will find its application in all sectors of economic activity in which it it is necessary to warn people of the risks of degenerative lumbar pathologies linked in particular to the maintenance in an unsuitable physiological position of the spinal column during a prolonged sitting position of the individual within the framework of activities of daily life at work or leisure .
  • the main object of the present invention is to obtain a seat accessory which makes it possible to mold the lumbo-gluteal structures while preserving their anatomo-physiological relationships specific to each individual.
  • the lumbar-gluteal anatomy adjusts to the shape of the seat, whereas, theoretically, the seat should adapt to the individual so as not to modify, in a lasting manner, the relationships anatomical lumbo-glutes specific to each person.
  • the consequence of this modification is excessive physical stress on the structures of the lumbosacral spine, which can lead to intermittent painful discomfort then permanent in the more or less long term, and all the more so since the subject is subjected to such pathologies in particular.
  • degenerative formed by an evolution of the cartilage resulting from a spontaneous progressive wear of this one and that this evolution is favored, moreover, by certain etiological factors.
  • the seat accessory 1 comprises an outer casing 2 defining a structure 3 inside which is placed a liquid filling fluid capable of being put into circulation.
  • Said structure 3 comprises means 4 to allow a distribution and a slow and controlled channeling of said liquid fluid in order to ensure a conformation of this structure 3 able to match the morphology of the user.
  • These means 4 are constituted by a network of transverse cells 5 communicating with each other, such as that which is more particularly illustrated in FIG. 4.
  • These cells 5, in the illustrated embodiment communicating with one another via baffles 6 formed by through an orifice 7 formed at at least one of their ends, with a view to authorizing a slow and controlled circulation of said liquid fluid, along a path shown by the arrows referenced 9, which also makes it possible to maintain the liquid fluid in order to keep the accessory 1 the desired shape when at least part of it is in the vertical position.
  • each interalveolar communication end 7 has a vertical bulge 8 limiting the circulation speeds of the liquid so as to constitute a hydraulic pressure drop and to ensure a channeling of the circulation of the fluid.
  • the orifices 7 ensuring inter-cellular communication are staggered from one end of a cell to the other end of the underlying cell in order to facilitate the flow and the hydraulic circulation of said fluid along a path ensuring an adaptation of article 1, in accordance with the invention, to the morphology of the person.
  • each cell 5 is variable, and by way of example the diameter can be between 1 to 4 cm.
  • these cells 5 of variable diameter have a predetermined distribution so as to give the structure 3 a profile adapted according to the part of the body intended to be maintained.
  • the cells 5 are obtained by hot welding of the base material constituting the envelope 2, which can for example be a heat-sealable plastic material. such as polypropylene or any other material having appropriate characteristics of solidity and flexibility, so as to create the structure 3.
  • a heat-sealable plastic material such as polypropylene or any other material having appropriate characteristics of solidity and flexibility
  • the envelope 2 may consist of two superimposed sheets of the base material or a sheet folded back on itself.
  • the fluid used can be water comprising additives so as to give it a viscosity sufficient to limit its too rapid flow inside the cells 5.
  • sucrose or any other adjuvant may be added in liquid form or in the form of a gel to said fluid in order to give it suitable viscosity properties.
  • this liquid fluid may also be advantageous to add to this liquid fluid, for example a fungicidal agent to avoid the risks of introduction of molds or pathogens when said fluid is enclosed in the envelope 2, as well as an antifreeze agent. to keep the liquid its suitable fluidity whatever the temperature at which the accessory 1 is used, which increases its usability.
  • a fungicidal agent to avoid the risks of introduction of molds or pathogens when said fluid is enclosed in the envelope 2, as well as an antifreeze agent.
  • the fluids that may be used as well as the adjuvants associated with them have characteristics that meet the hygiene and / or toxicity standards required for uses intended for people, in particular to avoid the risk of accidents. in case of unexpected contact of these products with the user's skin.
  • the seat accessory 1 here consists of two independent parts 11 and 12 connected together by means of a fold line 13 which extends over the entire width of these.
  • Each part 11-12 has dimensions adapted to allow its adjustment on a flexible or rigid seat 14, such as for example a car seat or an office seat and as is more particularly illustrated in FIG. 6.
  • Part 11 is intended to cover at least partially the backrest 14a of seat 14, while part 12 is intended to cover at least partially seat 14b of said seat 14.
  • the part 11 in the position of use has two external flexible lateral beads 15 and 16 extending respectively in the vicinity of each lateral border, intended to mold the lateral parts of the lumbo-gluteal region A of the individual and, on the other share a horizontal progressive bulge 17 of its median part which ensures a molding of the physiological lumbar lordosis B.
  • This progressive bulge 17 is, moreover, obtained by means of the progressive increase in this zone of the diameter of the alveoli 5 like this is more particularly illustrated in FIG. 5.
  • this part 11 ensures the maintenance of the physiological lordosis of the lumbar spine up to an upper limit which is situated approximately above the dorso-lumbar hinge corresponding to the transition zone of the end of the dorsal kyphosis. physiological towards lumbar lordosis.
  • Part 12 has, when the individual is in a seated position, two flexible beads 18, 19 which extend respectively in the vicinity of each of its lateral edges, as is more particularly illustrated in FIG. 3.
  • the molding of the part posterior thigh will be obtained by gradually increasing the diameter of the cells 5 in this area, as shown by the arrow 20 in FIG. 6.
  • this part 12 maintains the sacred portion of the column comprising the pelvis and the sacrum and the proximal part of the lower limbs C. It should be noted that this part 12 is essential insofar as the position of the pelvis can , alone, change the position of the spine. Indeed, a simple tilting of the pelvis forward and down abnormally accentuates the lumbar lordosis while a simple tilting of the pelvis backwards and upwards generates a reduction of this lordosis.
  • parts 11 and 12 as well as their immediate adjustment to the individual and to his movements, thanks to the movements of the liquid filling fluid contained inside these two parts 11 and 12 allow an appropriate molding of the sitting position of the individual, that is to say the lumbosacral column of the pelvis and the proximal part of the lower limbs.
  • These heating elements 21 can be constituted for example by a heating resistor 22 associated with a thermostat 23 making it possible to control the desired temperature to which it is desired to bring the fluid.
  • the connection of the resistor 22 is also carried out in such a way that it presents total security so as to avoid the risk of electric shock.
  • Figures 7 and 8 show an alternative embodiment of the seat accessory of the present invention.
  • the seat upholstery 1 is constituted as in the previous embodiment and comprises an external envelope 2 defining an internal structure in which is placed a liquid filling fluid, capable of being put into circulation.
  • This structure comprises a network of transverse cells communicating with each other, surrounded by a peripheral bead.
  • the bead is continuous and formed by an upper alveolus 21 and a horizontal lower alveolus 22, joined by two lateral vertical alveoli 23-24.
  • Said network is itself constituted by in particular eight cells 26-33, transverse communicating with each other, via baffles formed by orifices formed at at least one of their ends, arranged in staggered rows, in order to allow a slow and controlled circulation of the liquid.
  • each communication end may have a bulge 33, constituting for said communication orifice a constriction to constitute a hydraulic pressure drop and channel the circulation of the liquid.
  • the seat part 37 and the back part 36 communicate through the orifice 34 of the network of cells, the folding axis of the seat upholstery being shown diagrammatically by the dashed line marked 35 on the figure.
  • the profile of the cells is variable depending on the part of the body to be maintained, and for example the lateral beads 21-24 are of a width of the order of 20 to 50 mm, similarly for the lower cells 31- 33.
  • the other cells form oblong lights and for example the cells 26, 28 have a height between 50 and 100 mm, the cells 27, 29 have a height between 80 and 150 mm, while the cell 30 under the buttocks has a dimension of l '' from 100 to 200 mm.
  • the fact that the structure is pre-shaped to the camber of the spine, combined with the means allowing its vertical fixing, allows automatic compensation for movements and deformations of the column and the sacrum.
  • the gasket also has a filling valve 38 as well as a drain plug 39.
