Seat

Abstract

It is a seat that basically consists of a structural cover that is split into compartments that, in the specific case of a sofa, has different cavities for the backrest, seat, armrest and other parts of the sofa, in such a way that bags filled with a lightweight material can be fitted into and adjusted inside these cavities, so that these bags are really the elements that serve to reinforce the sofa as a whole, thus obtaining a low-cost and lightweight product that is easy to transport because of its slight volume as a result of it being possible to dismantle it before transporting it, which sets it apart from most conventional sofas, which have to be moved in their completely assembled form. The bags can be composed of a single compartment or several, in which case each compartment may in turn be filled with different materials in order to obtain different degrees of flexibility.

1 . A seat, such as a sofa or similar, of the type that contains light filling material in the form of granules contained in bags in a similar way to cushions with different layouts, characterised by the fact that it contains an outer cover ( 1 ) as a structural element, which is flexible in nature, preferably made of textile material or similar, provided with inner partitions ( 5 ) that help to enhance the structural function and serve to form several compartments ( 2 ) inside the piece of furniture, each of which is provided with intakes, and occupied by the respective bags ( 3 ) containing filling material, the cover and bags constituting a compact assembly that can be adjusted with means for closure that can keep the general layout of the piece of furniture stable as pressure is exerted upon it when it is being used for the purpose for which it is intended. 
   
   
       2 . A seat, as in  claim 1 , characterised by the fact that each bag ( 3 ) has at least one compartment, which contains the filling material ( 4 ), which can be perlite, polymers, polypropylene, polystyrene, polyethylene or similar materials. 
   
   
       3 . A seat, as in  claim 2 , characterised by the fact that the bags ( 3 ) have an internal substructure composed of internal partitions ( 10 ) that separate different compartments ( 12 ) occupied by the filling material ( 4 ). 
   
   
       4 . A seat, as in  claim 3 , characterised by the fact that the internal substructure of the bags ( 3 ) has intakes ( 11 ) incorporated into the internal partitions ( 10 ), which serve to connect adjacent compartments ( 12 ). 
   
   
       5 . A seat, as in  claim 3 , characterised by the fact that the internal partitions ( 10 ) in the bags ( 3 ) create independent compartments ( 12 ′) so that they can be filled with different filling materials with different densities. 
   
   
       6 . A seat, as in  claim 1 , characterised by the fact that it has at least one rigid body ( 14 ) incorporated into the filling material ( 4 ) a sheeting element being positioned in between ( 16 ); all of this being provided with a view to making the softened bodies formed by the bags ( 3 ) solid and to giving them substance. 
   
   
       7 . A seat, as in  claim 2 , characterised by the fact that the bags ( 3 ) have at least one intake ( 13 ) leading into them, equipped with means for closure. 
   
   
       8 . A seat, as in  claim 3 , characterised by the fact that the bags with an internal substructure are equipped with one single communal intake ( 13 ). 
   
   
       9 . A seat, as in  claim 5 , characterised by the fact that the independent compartments ( 12 ′) each have intakes ( 13 ). 
   
   
       10 . A seat, as in  claim 1 , characterised by the fact that at least the external covering for bags contains a heat-sealable material; all of this is provided in order to give the bag its shape by joining up its different parts by heat-sealing and with the possibility of closing the intakes ( 13 ) also by heat-sealing. 
   
   
       11 . A seat, as in  claim 10 , characterised by the fact that the heat-sealable material for the bags ( 3 ) is impermeable and has micro-perforations. 
   
   
       12 . A seat, as in  claim 1 , characterised by the fact that the cover split into compartments ( 1 ) is covered with a second outer cover ( 15 ) that is decorative. 
   
   
       13 . A seat, as in  claim 6 , characterised by the fact that the sheeting element ( 16 ) that covers the rigid body ( 14 ) forms an essential part of the material that encapsulates the bag ( 3 ). 
   
   
       14 . A seat, as in  claim 6 , characterised by the fact that the sheeting element ( 16 ) that covers the rigid body ( 14 ) has an independent body that is joined to the material that encapsulates the bag ( 3 ). 
   
   
       15 . A seat, as in  claim 1 , characterised by the fact that the compartments in the structural cover ( 1 ) are filled with or contain blocks or pieces ( 17 ) of material that is elastomeric or similar.
