Definitions

  • the invention relates to a mattress made of a block of elastic flexible polyurethane foam, which has at least on one of the two surfaces mutually parallel incisions both in the longitudinal direction and in the transverse direction, the depth of which is about 1/4 to 1/3 of the mattress thickness and where the incisions in the longitudinal direction of the mattress run at equal distances from one another.
  • Such a mattress is known from BE-A-682 014.
  • the incisions in the transverse direction are each at the same distance from each other, so that the mattress has the same overall hardness and resistance to stresses.
  • a mattress is loaded to different extents by a person lying on it, with a higher load occurring in particular in the shoulder area and in the pelvic area, but this is compensated accordingly by the point-elastic properties of a foam mattress.
  • the present invention is therefore based on the object of creating a mattress in which the point elasticity is increased with extremely simple means and a targeted support function can be achieved without, however, preventing or reducing the characteristic features and the suspension behavior.
  • the incisions in the transverse direction have a smaller distance from one another in approximately the first third and the incisions in the last third of the mattress length than the incisions in the middle third.
  • the incisions in the middle region of the mattress length are expediently approximately twice as large as in the other regions.
  • At least the incisions in the transverse direction of the mattress can have an inwardly widening, teardrop-shaped cross section.
  • This design allows greater flexibility of the foam segments on the longitudinal axis of the mattress core realize. This also increases the material's adaptability to the body contour. Furthermore, these tear-shaped cross cuts offer a lower risk of the material tearing at these critical points. Another effect is that these teardrop-shaped incisions form air channels, which increases the air permeability and improves the ventilation.
  • the incisions expediently consist of vertical cuts in the longitudinal direction without material removal or can have a narrow, rectangular cross section, which requires only a small amount of material removal. Finally, it is also expedient if the respective first incision is at a greater distance parallel to a mattress edge than the average distance of the other incisions from one another.
  • the mattress 1 has a block of soft elastic polyurethane foam, usually in the form of conventional polyether or HR foam, both on its top 2 and its bottom 3 transversely to the longitudinal direction of the mattress 1 extending incisions 4, 5 and 6, which can be simply formed as vertical cuts or, according to the illustrated embodiment, with a teardrop-shaped cross section widened downwards.
  • a block of soft elastic polyurethane foam usually in the form of conventional polyether or HR foam
  • cuts 7 and 8 are also provided in parallel in the longitudinal direction of the mattress 1, which have a narrow, rectangular cross section according to FIG. 2 with corresponding material removal, and are designed as simple cuts 8 according to FIG. 3.
  • the transverse incisions 4, 5 and 6 and the longitudinal incisions 7 and 8 extend over a height of approximately a quarter to a third of the total thickness of the mattress 1.
  • the vertically intersecting incisions 4, 5, 6 and 8 discrete surface sections 9 of a square or rectangular surface are thus cut free, which can separate or deform elastically under load independently of the surrounding surface elements.
  • the transverse incisions 4, 5, 6 in particular can have different distances from one another.
  • the distances between the incisions 4 in the first third of the mattress 1 and the distances between the incisions 6 in the third third are smaller than the distances between the incisions 5 in the central region. So the mattress works e.g. softer in the shoulder area, although the overall suspension behavior of the mattress block remains unchanged and the material's own restoring energy is retained.
  • the respective edge areas 10, 11, 12 and 13 have only incisions over a wider area that are perpendicular to the respective edge. As a result, a higher seating stability is achieved on the edges of such a mattress provided with incisions.
