Definitions

  • this invention is a seat whose distinctive feature is that there is no internal rigid structure to serve as a support for the seat, although this in no way detracts from the required convenience and comfort of the piece of furniture in question.
  • the conventional technique consists of establishing an internal structure that is rigid, generally made of wood, upon which the different parts and elements with a softening effect are assembled with a view to achieving the desired level of comfort.
  • European patent 0 284 294 is a chair for geriatrics consisting of water bags, which can logically be stored and transported easily when the bags are empty and they weigh very little, but this is not the case with their volume, because a fixed structure is required to support the bags, and it must also be pointed out that the deformability of the bags is excessive and that even though the chair might be suitable for solving the problems that are faced by certain senior citizens, this does not apply when it comes to a conventional seat.
  • Patent GB 1.300.733 is a cushion with one single conventional chamber that can be stuffed with fillings of different kinds, to afford different degrees of hardness, but it is clear that this cushion solution cannot be applied directly to a sofa, for example, where there have to be self-supporting elements that limit its deformability, especially where armrests and the backrest are concerned.
  • a mattress has also been developed bearing US Patent 4843666 , based on a receptacle into which a variety of pads of different hardness are inserted, so that the hardness throughout the entire mattress is ideally suited to the different parts of the body that will be lying on them, yet the functionality of this mattress lies in the fact that it is supported on a flat and rigid surface, so that if this technology were to be applied to a sofa, it would have to be arranged in a rigid structure, which as has already been pointed out is undesirable because of its weight and volume, among other negative factors.
  • Patent WO 9602402 describes a seat that has a rigid frame, referenced as (12)-(13), upon which two superimposed compartments are mounted that are filled with fluid. This solution is along the structural lines of European Patent 0 284 294 , so the same considerations made about the latter are valid.
  • the seat that is the object of the invention is mainly characterised by the fact that it is equipped with a series of bags filled with a softening material with different degrees of hardness and density, for example of the perlite or granulated type, although any other product might be suitable.
  • Grains of the lightest types of material are normally used that are easy to fill by pneumatic means, such as polymers, polypropylene, polystyrene, polyethylene, etc.
  • Each one of these bags containing the filler material forms part of the seat, in such a way that a sofa might have, for example, one bag for each armrest, another one for the backrest, another one for the horizontal part of the seat, etc, with the same density or different densities.
  • the aim of the above-mentioned bags is to fill up what could be referred to as the structure of the sofa or seat in question, consisting of a flexible cover that is split into compartments, preferably made of a textile or something similar, which on the one hand coincides in form and size with the perimeter of the piece of furniture, and that on the other hand is equipped with inner partitions of the same type, which not only make the structure of the cover rigid, but also serve as a housing for the aforementioned different bags or groups of bags, and each one of the compartments has at least one intake equipped with means for closure, such as a zip, for example.
  • each segmented space will have an intake so that the bags inside can be adjusted, although it is also possible that several segmented spaces might have one single intake when the individual space in question is larger.
  • each one of the bags has a substructure composed of intermediate partitions that separate different compartments, and give the bag its rigid nature, these partitions being provided with passages that connect up with the adjacent compartments, so that the filling process for these compartments takes place as swiftly and, above all, as correctly as possible, without there being any risk of hollows or empty spaces.
  • bag compartments that are independent, so that they can be filled with different materials and thus different densities, thereby obtaining different degrees of hardness that can be adapted to the ergonomics of the seat and, all in all, greater comfort for the user.
  • each compartment has its own intake, although it would also be possible for there to be one single communal intake, as long as one of the ends of the compartments leads to this communal intake.
  • Another characteristic of the invention is that the bags are provided with reinforcements at the edges in the places where these coincide with the edges of the sofa, in such a way that this characteristic, together with the insertion of intermediate partitions, makes the seat more rigid and solid, so that it does not flatten when the user sits down on it.
  • the reinforcements can also be placed on the corners of the bags.
  • the covers basically made of foam material, which eventually makes them look like a traditional armchair.
  • an outer cover is placed over them to give them look appealing, and this cover may either be made of leather, cloth or any other textile.
  • the bags are normally made of textile materials and even those that are mentioned above, although it is also possible to manufacture the bags heat-sealable material, the different parts being joined together by heat-sealing, as well as the intakes. Even when this heat-sealable material is impermeable, it will contain micro-perforations to enable the release of air while the bags are being filled, thereby preventing vacuums from forming and defects appearing in them.
  • the seat is initially composed of at least one flexible foam cover (1) that is split into compartments where several open cavities are defined (2) in which the respective bags (3) are adapted with a filling material (4), made of perlite or other granulated materials, in such a way that as soon as these bags (3) are inserted and adjusted within the cavities (4), they are closed, thus forming and strengthening the seat assembly.
  • the edges of the bags, and even the corners, are equipped with reinforcements (6) and (7) in order give the seat assembly a better shape.
  • cover (1) may also be provided with reinforcements (8) and (9) at the edges and, above all, at the corners.
  • Each one of the bags (3) constitutes a part of the seat, in such a way that in the specific case of a sofa, we have one bag (3) for each armrest, one for the sofa backrest and another one for the seat, etc.
  • the sofa will be covered with an outer decorative cover (15) that can be made of a wide variety of materials.
  • the bags can also be made to contain one single compartment containing a filling material, such as can be seen in Figure 3 , although the bags can also be given different layouts and structures, such as those shown in Figures 5 to 8 .
  • the bag (3) can have an internal substructure that is composed of internal partitions (10) that separate different compartments (12), partitions that are provided with intakes (11) between the compartments so that the process of filling these compartments can be both as rapid and correct as possible, making sure that there are no vacuums created or empty spaces left, as well as guaranteeing that there are no variations in the density of a volume occupied by the same type of filling material (4).
  • the compartments (12') in the bags (3) be independent so that they can be filled up with different materials, that thus have different densities, thereby making sure that the hardness can be different and adapted to the ergonomics of the seat and, all in all, make it more comfortable to sit in.
  • each compartment (12) has its own intake (13), although it would also be possible to have one single communal intake, as long as one of the ends of the compartments (12) leads to this communal intake (13).
  • the cavities (2) in the flexible structural cover (1) can optionally accommodate blocks or pieces (17) of material that is elastomeric or similar, instead of the aforementioned bags (3), in order to modify the hardness, comfort of the seat, etc.
