Definitions

  • This invention relates to a device for regulating the hardness of the seat of a sofa in such a way that it can easily be adapted to the user's preferences.
  • a device that allows the hardness of the seat to be modified by the user him/herself and, therefore, avoids deformation of the seats due to their use is therefore required. This problem is solved by the device for regulating the hardness of a seat which is the object of this invention.
  • an object of this invention is a device for regulating the hardness of a seat. More specifically, an object of the invention is to enable each user to achieve an adapted degree of hardness quickly and easily. These objects are achieved with the device according to claim 1. Particular solutions of this invention are described in the dependent claims.
  • the device for regulating the hardness of a seat recommended by this invention is characterised in that it comprises a plurality of first flexible elements as the lower support for the seat cushion and a rigid element, movable in a plurality of working positions in the part immediately below the plurality of flexible elements and in contact with them perpendicularly, such that each working position exerts a different pressure on the flexible support elements.
  • the flexible elements can be configured -in two practical, non-limiting embodiments- in elastic straps and/or flexible plastic suspension slats.
  • plastic parts exist for joining the slats of settees and mattress bases which, by joining them together, can slightly increase or reduce the hardness of the suspension, but the difference in hardness achieved is minimal, whereas, thanks to this invention, it is possible to achieve extreme differences in hardness.
  • the rigid element is configured as a bar that exerts pressure on the lower part of the flexible elements (either straps or slats) such that, as it moves or changes position, it causes a change to the hardness of the seat.
  • This rigid element can be motorised, or it can be an element that can be moved manually between predefined positions, which, in the tests performed, makes it possible to go from 100% flexibility of the flexible elements -in other words, without the rigid element exerting any action or force on the flexible elements- to 30% or 40% of the original flexibility of said elements, for example, by placing the rigid element in a centred position with respect to the flexible elements that constitute the support of the seat cushion.
  • each user can regulate the hardness of his/her seat, and different types of hardness, harder or softer, can coexist in the same sofa.
  • This choice of hardness is totally reversible.
  • the sofa comprises two seat modules (10, 20) where the seat cushions themselves will be located.
  • both seats (10,20) it can be seen how they are configured by a plurality of flexible elements (11,21), which, in this practical embodiment are flexible plastic slats, they could also be flexible straps.
  • These flexible elements (11,21) are arranged transversally with respect to the seat, in other words, they have the same maximum length as the seat and are configured as the lower support for the cushions that makes up said seat, as indicated above.
  • a motorised rigid element (12) is arranged perpendicularly to the flexible elements (11) configured in an embodiment that is in contact with the lower surface of the flexible elements (11) and configured to exert pressure on said flexible elements during their displacement.
  • the rigid element (12) is movable from a first working position, wherein the rigid element (12) is fully retracted into the internal part of the seat (i.e., the part closest to the backrest) and wherein it exerts no pressure on the flexible elements (11) to a second working position, wherein the rigid element (12) is in a closed centred position with respect to the length of the flexible elements (11), such that it exerts a maximum pressure on said flexible elements (11) and consequently increasing the sensation of seat hardness.
  • the rigid element (12) moves on an axis (13) arranged in the middle of the seat which is operated manually by means of a motor (14) and which, due to its backwards to forwards movement, and vice versa, manages to regulate the flexibility of the flexible elements (11) and, therefore, their hardness.
  • a second practical embodiment can be seen, more specifically, in the second seat (20).
  • the flexible elements (21) are located identically to those of the first embodiment, but there is no motorised axis, but two guides (22 and 23) are simply positioned on both sides of the seat, facing each other and in parallel.
  • Each of the aforementioned guides (22,23) has a plurality of housings (24) suitable for manually receiving a rigid element or crosspiece (12) in the housings (24), depending on the hardness required, by manually positioning the bar between a first working position, wherein the rigid element will be more to one side, or in any other more centred working position and defined by each pair of housings (24) facing each other.
