Definitions

  • the invention relates to a device for supporting the human body, such as a mattress, comprising a body that comprises a resilient plastic material, said body being provided with a plurality of first channels essentially parallel to one another, as well as a plurality of second channels essentially parallel to one another, the first channels and the second channels extending at an angle with respect to one another, and the body comprising a plurality of layers, each of which is provided with channels.
  • This device is, for example, a mattress or a seat cushion for sofas or other elements supporting the body.
  • a device of this type is disclosed in GB 2 274 054. Because this mattress is made of a resilient plastic material, such as foam, it is inexpensive compared with, for example, a mattress that is provided with interior springs. However, the ventilation characteristics of foam are poor. Usually, moisture that is secreted by the human body and passes into a foam mattress cannot be expelled readily by the foam. The moisture then remains behind in the upward-facing surface of the mattress. Consequently, a foam mattress generally feels clammy, which is uncomfortable and unhealthy for a user. The first and second channels disclosed in GB 2 274 054 are able to expel moisture from the upward-facing surface of the mattress.
  • the known device is relatively of lighter weight as a result of the use of the channels. This saving in weight is advantageous, for example, if a user has to move the mattress or has to lift it to some extent when making a bed.
  • An object of the invention is to provide an improved device for supporting the human body.
  • At least one layer comprises individual, optionally joined, elongated strips which are arranged some distance apart to form the channels between them.
  • the construction of individual, optionally joined strips is simple and flexible. Moreover, the device according to the invention is more comfortable.
  • the channels are located between the strips. These channels can be formed by positioning individual strips some distance apart, leaving the channels open between them.
  • the strips are, for example, joined to an upper and/or lower layer by gluing.
  • the channels can also be formed by milling or with the aid of heated wires which cut out the channels in the plastic material.
  • One embodiment of the device according to the invention is characterised in that a first strip in a layer has a relative density that differs from the relative density of a second strip in the same layer.
  • One embodiment of the device according to the invention is characterised in that a strip in a first layer has a relative density that differs from the relative density of a strip in a second layer. It is possible not only for the relative density of strips in a given layer to differ, but also for the relative density of strips in different layers to differ. This embodiment makes a further variation in the firmness of the mattress possible. The support by and the comfort of the mattress are even better.
  • a final layer of the body can contain channels that are constructed as open slots.
  • the slots in the final layer extend in the longitudinal direction of the body.
  • the slots can also extend in the width direction of the body. If the slots are no wider than two or three cm, a user will barely notice the presence of the slots. The expelling of moisture is, however, excellent, as a result of which the mattress is felt to be cool.
  • the strips in one layer are glued to strips in an adjacent layer, the adhesive preferably being water-based.
  • Water-based adhesive is environmentally friendly.
  • the resilient plastic material is preferably polyether.
  • the relative density of the polyether is, for example, between 35 and 70 kg/m 3 , but preferably between 35 and 40 kg/m 3 .
  • the invention also relates to an assembly of a device as described above and a mattress, the device as described above being placed as a covering on the mattress.
  • This mattress can be, for example, an interior-sprung mattress, the abovementioned advantages also being achieved by the use of the device as described above as top layer.
  • the device shown in Fig. 1 for supporting the human body is indicated in its entirety by 1.
  • This device comprises an elongated body 2 that forms a mattress.
  • the dimensions of the device 1 are, however, not of importance for the invention.
  • the device 1 could, for example, also be a seat cushion for a sofa.
  • the elongated body 2 is made of a resilient plastic material, such as foam.
  • the illustrative embodiment of the device 1 according to the invention shown in Fig. 1 is constituted of 4 layers, 3, 4, 5, 6 respectively. Each of these layers 3, 4, 5, 6 has elongated strips 9, which are arranged some distance apart. In this way first channels 10 and second channels 11 are formed between the strips 9.
  • the first channels 10 extend essentially in the width direction of the body 2, whilst the second channels 11 run essentially in the longitudinal direction of the body 2.
  • the mutually parallel first channels 10 are positioned at an angle ( ⁇ ) of 90° with respect to the mutually parallel second channels 11.
  • the channel structure formed in this way in the body 2 provides for good moisture regulation. Moisture that is secreted by a user who has laid down on the device 1 is effectively expelled through the channel structure. The user consequently finds the device 1 to be cool.
  • the relative density of strips 9 in a single layer it is possible to vary the relative density of strips 9 in a single layer.
  • the strips 91, 92 in the layer 5 have, for example, a higher relative density than the other strips in this layer 5. As a result the device 1 will be firmer in the region of the strips 91, 92.
  • the mattress adapts better to the contours of the human body of the user.
  • the relative density of a strip in one layer can, for example, be less than the relative density of the strip 96 in the layer 6. It would be possible, for example, to counteract sagging of the mattress by this means. Of course, it is also possible that the relative density of the strip 95 in the layer 4 also differs from the relative density of the strips 91, 92 in the layer 5.
  • the channels in the final layer 8 on the top of the mattress run in the longitudinal direction.
  • the top layer or another layer is essentially continuous or closed (not shown).
  • the device 1 shown in Fig. 1 has six strips 9 in the width direction, as a result of which 5 channels are formed in the width direction.
  • the device according to the invention can, however, also comprise a different number of strips and slots.
  • the channels are, for example, 2-3 cm thick and the strips 10-11 cm wide, depending on the width of the mattress and the width of the channels.
  • the strips 9 of the device 1 according to the invention are glued to one another.
  • the adhesive used is preferably water-based, because water-based adhesive causes less environmental pollution.
  • the material of the device 1 according to the invention is, for example, polyether, polyethylene, or polyurethane.
  • the relative density of the polyether is, for example, between 35 and 70 kg/m 3 , such as 35, 40, 60 and 70 kg/m 3 .
  • the device 1 according to the invention is less heavy because of the incorporation of the channels 10, 11.
  • This saving in weight is attractive when using the mattress, for example if a user has to lift the mattress to some extent when making a bed.
  • the saving in weight is approximately between 10 and 15 %.
  • the assembly shown in Fig. 2 comprises a device according to the invention 20 and a mattress, for example a mattress that is provided with interior springs.
  • the slots in the device 20 according to the invention have, for example, been made with the aid of heated wires.
  • the individual elongated strips are joined to one another by a cross-piece at the bottom, but the join could equally well be achieved in another way or at a different location.
  • the device 20 can, moreover, also have been made up of strips that are glued to one another.
  • the layers 3, 4, 5, 6, 7 can also vary in thickness. Variation in the thickness of the layers is an alternative means of forming firmer and softer regions in the mattress for optimum support of the human body of the user.
  • Fig. 4 it is furthermore indicated that the strips 9 can also vary in width.
  • the channels 10 between the strips 9 are unequal distances apart. In this way it is also possible to achieve an embodiment with variation in flexibility of the mattress, so that a tailor-made mattress can be produced.
