Definitions

  • the invention relates essentially to the field of bedding.
  • the invention relates to the field of design and production of mattresses and structurally similar elements such as cushions, incorporating means for adjusting their firmness and therefore modulating comfort they provide according to the wishes of their user.
  • the international patent application WO-A-9604825 filed on August 15 1995 describes a mattress consisting of an envelope inside which are arranged side by side, parallel to the longitudinal axis of said mattress, a plurality of filled tubes air or another fluid, each of these tubes being equipped with a device making it possible to regulate the pressure prevailing therein.
  • This type of mattress has a large number of drawbacks.
  • the entire envelope is occupied by tubes inflatable, it provides basic comfort comparable to that of inflatable mattresses used for camping, and induces for the user a feeling of floating and rolling.
  • each tube being provided with an individual regulation device of air pressure or other fluid prevailing therein, obtaining the degree of firmness desired by the user is long to obtain, this user having to adjust in turn the firmness of each of the tubes.
  • Such a mattress having inflatable tubes provided parallel to its axis longitudinal it does not allow to adjust the firmness according to the different parts of the body of the user (back, legs, head) installed there.
  • This type of mattress also has drawbacks.
  • An objective of the present invention is to provide a mattress or an element structurally similar, such as a cushion, incorporating means for adjusting its firmness and not having the drawbacks of the devices known from the state of the technical.
  • one of the objectives of the present invention is to propose such a mattress whose firmness can be easily and quickly adjusted.
  • Yet another object of the present invention is to describe such a mattress which provides variable firmness depending on the areas of said mattress.
  • a mattress with a honeycomb structure characterized in that it comprises at least one layer of a highly deformable material delimiting a plurality of cells, a plurality of self-inflating elements housed in at least some of said cells, and at least one pressure regulation device prevailing in said self-inflating elements making it possible to adjust the firmness of said mattress.
  • self-inflating elements aim to cover elements swollen by a gas, preferably air, and which can be deflated when a load (for example the weight of a user) is applied to them, and automatically re-inflate at least when they no longer support said load.
  • the invention proposes to combine the use of such elements self-inflating with that of cells formed in a highly deformable material (said material which can be constituted for example by a layer or a superposition of layers of foam) to accommodate such elements, and with the use of means for adjusting the pressure prevailing in these elements and thus the firmness of the mattress.
  • a highly deformable material such material which can be constituted for example by a layer or a superposition of layers of foam
  • the self-inflating elements being housed in cells, they do not induce the user of a floating and / or rolling sensation conventionally encountered with mattresses with inflatable structures, but on the contrary contribute to the comfort of the mattress.
  • the mattress comprises a unique device for regulating the prevailing pressure in all of said self-inflating elements.
  • a unique device will have the advantage of be able to be easily and quickly handled by the user. To this end, we can plan to install it in a place easily accessible by it, for example on the side of the mattress.
  • the use of a single regulation device does not prevent not to obtain a variable firmness depending on the areas of the mattress since we can plan for this purpose to install these elements in greater numbers in the areas where we wish obtain greater firmness.
  • said elements self-inflating and said cells are provided transversely to the longitudinal axis of said mattress.
  • Such a characteristic has the advantage of inducing more comfort than a positioning parallel to the longitudinal axis of the mattress, i.e. to the axis along which the user is lying on the mattress.
  • said cells consist of a first type of cells accommodating said self-inflatable elements and a second type of cells not accommodating a self-inflating element.
  • the second type of cells is intended to maintain the comfort of the mattress even when the self-inflating elements are completely deflated.
  • said self-inflatable elements have a cross section cross-section essentially circular and are thus in the form of tubes.
  • said first type of cells has a section essentially polygonal.
  • Such a section does not advantageously correspond not to that of the self-inflating elements which, as specified above is preferably circular. It has indeed been found that in this way, any sensation user rolling or floating on the mattress was suppressed.
  • said device for regulating the pressure prevailing in said self-inflatable elements comprises a regulating valve allowing the air present in said self-inflatable elements to escape when a load is applied on them and allowing the entry of air into said elements when no load is applied to said self-inflating elements, up to the establishment of a nominal pressure in said self-inflating elements.
  • said valve allows a slow escape of the air contained in said self-inflating elements and a rapid air inlet therein.
  • said regulating device includes means for forced inflation of said self-inflatable elements.
  • means of Forced inflation could thus include a pump which will allow the user to inflate the self-inflating elements while remaining on the mattress.
  • the mattress includes a complex of layers of foam of varying densities.
  • the mattress has means for connecting at least at least two self-inflating elements between them.
  • Such connecting means allow the communication of the fluid swelling these two elements from one element to another.
  • the mattress according to the invention can be used as a mattress domestic, the invention also covers any use of such a mattress as medical bed mattress.
  • the mattress according to the invention comprises a plate upper foam 1 and a lower foam plate 2 forming a sole.
  • the foam used to constitute the upper plate 1 is the same as that used to constitute the upper plate 2 but we can of course also use foams of different natures and / or densities.
  • the mattress according to the invention also comprises three self-inflating elements 5 in the form of tubes positioned in the cells of pentagonal section 4, that is to say transversely to the longitudinal axis of said mattress.
  • These self-inflating elements 5 are connected by three flexible pipes 8 to a device 6 for regulating the pressure prevailing in these three elements, including a valve 7 and a plug 10 and which will be described in more detail with reference to FIG. 2. (It will be noted that in other embodiments, it may be provided with more than three self-inflating elements distributed equally or unevenly)
  • the three self-inflating elements 5 of the mattress are distributed unevenly, one of these elements being installed in the area of the mattress on which the head will rest or the user's shoulders while the other two are installed at the level the area of the mattress on which the user's back or buttocks will rest.
  • the mattress also includes an envelope, not shown for needs clarity of the description, incorporating the constituent elements described above, to the exception of the plug 10 of the regulating device 6 which itself exceeds said envelope, to allow the user to maneuver it.
  • this regulating device 6 is advantageously provided on the side of the mattress.
  • Such a pressure regulating device makes it possible to slowly expel the desired amount of air from self-inflating elements, when a load is applied to these, and on the other hand allows air to enter these elements quickly for them automatically re-inflate as soon as the load in question ceases to be applied to the said elements.
  • the user can lie on the mattress, its weight then constituting a load on said self-inflating elements 5, unscrew the plug 10 to deflate more or less these elements until the degree of firmness he wishes is obtained, then screw the plug 10 so as to maintain the pressure thus established in these elements.
  • comfort cells 3 of triangular cross section allows maintain the comfort of the mattress even when the self-inflating tubes are completely deflated.
  • the user When the user wishes to change the degree of firmness determined by the pressure prevailing in the self-inflating elements, it can, before lying down on the mattress, unscrew the plug 10 to re-inflate the self-inflating elements.
  • the mattress described therefore has great flexibility of use and allows obtaining a variable degree of firmness thereof, depending on the desire for the user.
