Definitions

  • the present invention relates to a method for manufacturing a mattress and a mattress produced by such a method.
  • this mattress does not take account of the fact that a person during its sleep takes various sleeping positions.
  • the sleeping positions or -postures of a person vary in the course of a night, without the person involved being aware thereof. It occurs quite seldom that a person does not change its sleeping position during a whole night.
  • a person can lie on its left side, its right side, its back or its belly. All in total a person can take four different sleeping positions during night.
  • European Patent application N° 3 023 034 A2 in the name of Perzona Benelux B.V., published on May 25, 2016 , discloses a mattress and a cushion, comprising a viscoelastic foam layer, with foam inserts embedded therein.
  • Fig. 3 C of this patent shows various inserts on discrete locations, having a different density or hardness, which is depicted on the figure by a different shading.
  • the aim of the present invention is to remedy the above and other drawbacks and to offer an appropriate solution by designing a mattress comprising various elements that can be assembled by the user as a function of his/her individual body constitution and lying position on an ideal mattress, support for the body.
  • the invention relates to a method for the production for a user of a mattress comprising a mattress core and inserts for various parts of the body of the user.
  • the method thereby comprises the following steps
  • the goal of this determination is that for the lying position of the user on the insert, the shape of his/her spinal column corresponds to the shape of his/her spinal column in upright position.
  • the selected inserts are positioned, fitted or deposited upon the lying side of the mattress core (that side of the mattress whereupon the user lies his body during sleep, so the upper side of the mattress).
  • a characterizing feature of the invention thereby is that for a given part of the body of the user, three inserts are used, namely a left-, a middle- and a right-insert.
  • the inserts are positioned on the lying side of the mattress core as follows:
  • each insert thereby is also determined as a function of the specific lying position of the user for the insert concerned. More in particular this determination is as follows:
  • the left and/or the right insert at its inner edge comprises a transition zone, the deformation characteristic whereof, expressed in hardness, is the average of the hardness of the left- resp. the right insert and the middle insert, and that the middle insert at one or both of its sides comprises one, resp. two transition zone (s), the deformation characteristic whereof, expressed in hardness, is the average of the hardness of the middle and the left-, resp. the right insert.
  • the invention also relates to a mattress, produced according to this method.
  • the invention relates to a method for the production of a mattress, as well as the mattress, manufactured by means of this process.
  • the mattress core is the basic or supporting element or means whereupon the inserts are positioned or deposited.
  • the inserts are parts, with a rectangular or in some cases square form, the characterising feature whereof is that the deformation in the vertical direction is adapted to the user.
  • the inserts can be replaced by a new set. So, the inserts are interchangeable in the course of time.
  • the thickness of the mattress core and the inserts together amount to 15 up to 30 cm in most cases, preferably between 20 and 25 cm.
  • the mattress core can be approximately 10 cm thick and the inserts can be 10 up to 15 cm thick, for example 12 cm.
  • the inserts are then designed such that their deformation, under the influence of the weight of a person lying in rest position thereon, is such that the position of the spinal column of the user as far as possible corresponds to the position of the spinal column of the person in upright position.
  • the deformation can be optimized or designed such that the position or shape of the spinal column of the user is as horizontal as possible.
  • FIG. 1 This is illustrated for example in figure 1 .
  • a person is shown in three different images near to each other, such person lying on his/her right-, back- or belly-, resp. left-side position.
  • these three sleeping positions are not executed on three different mattresses, but they are on the contrary applied on one and the same mattress, as shown in figure 2 .
  • a person during the night can take four different sleeping positions, namely:
  • the invention described as set forth hereinafter takes duly into account this situation that quite often occurs in practice; the goal of the invention consequently is to design a method that offers a suitable and practical solution to this problem. Differently phrased, the method should be designed such that the mattress manufactured according to this method yields an ideal sleeping comfort to the user, independently of the possible lying position of the user.
  • the method should thus be designed such that the form of the spinal column of the user, independently of his/her lying position on the mattress, still corresponds to the desired position or shape of the spinal column, namely the position or shape of the spinal column in upright position, and this irrespective of the sleeping position of the user.
  • the method to this end comprises the steps as set forth hereinafter in greater detail.
  • a first step in the method of the invention is the recording of a three-dimensional image of the user, in order to determine his/her body constitution and weight.
  • This recording can be executed according to a method and using means known in the art.
  • the next step in the method according to the invention is the determination of the desired deformation, expressed in a well-defined deformation characteristic, for example the hardness, for the various inserts for the various body zones.
  • the goal of this operation or step is that the deformation of the various inserts should be such that when the user is lying on the respective insert, the shape or position of his/her spinal column corresponds with the shape of his/her spinal column in upright position.
  • the design or fine-tuning of the desired deformation of the inserts takes place on the basis of the data resulting from the three-dimensional recording of the user, described above.
  • this design is created by means of a computer program that calculates how the user's personal 3D-profile in the mattress should be for the various body-zones and - according to the invention - for the various lying- or sleeping positions.
  • the conversion of the 3D data to a mattress-zone distribution according to the invention is not only in the vertical direction, this means optimized as a function of the various body-zones, but now also horizontally, namely for a given body-zone taking account of the left-, middle- or right- side or zone.
  • the goal of this design is that in the lying or sleeping position of the user on the insert, the shape or position of his/her spinal column corresponds to the shape of his/her spinal column in upright position.
  • the deformation of each insert to be determined comprises the determination of the desired deformation characteristic, for example hardness or density of the insert concerned, and the power-displacement curve of the chosen material for the insert concerned. In this way more or less deformation of the insert is obtained depending on the measured profile.
  • the program calculates on the basis of the 3D scan-measurement the power-displacement curve of the materials and by doing so the ideal sleeping position on the basis of the personal sleeping profile of the user.
  • the characteristic feature of the invention is that for a given body zone of the user, three inserts are available, namely a left-, a middle- and a right insert.
  • This figure shows a mattress, for example with a characteristic size, 100 cm wide and 200 cm long, whereby the user's head rests on top of the mattress and the user's feet rest at the bottom of the mattress.
  • the mattress is manufactured with inserts for up to seven different body zones:
  • Zone 1 Head & Neck 35 cm - Zone 2: Shoulders & Upper chest 21 cm - Zone 3: lower chest 21 cm - Zone 4: Waist & Lumbar 12 cm - Zone 5: Hips & bottom 27 cm - Zone 6: Upper legs & knees 42 cm - Zone 7: Lower legs & feet 42 cm.
  • the figure shows how for a given body zone, the insert knows as such in the state of the art (over the whole width of the mattress) now is divided in three different zones, a left-, a middle- and a right- insert.
  • the widths of the various inserts for a given body zone can vary as a function of the body zone.
  • figure 1 shows that for zone 1, the head and the neck, one single insert generally suffices.
  • zone 2 the middle zone or insert amounts to 60 cm (for a mattress with a total width of 100 cm) and both the outer zones, namely the left- and the right- zone or insert amount to 20 cm.
  • one or both of the outer inserts i.e. the left- and/or right insert, comprise an outer edge with a deformation characteristic, for example a hardness higher than the deformation characteristic, for example a hardness of the left-, resp. right- insert.
  • a deformation characteristic for example a hardness higher than the deformation characteristic, for example a hardness of the left-, resp. right- insert.
  • each insert is also determined as a function of the specific lying position of the user on the insert concerned. This determination is executed as follows:
  • the left- resp. the right side of a user is to be understood as that side or part of the person from his/her point of view.
  • the left- resp. the right side of the mattress is to be understood as that side or part of the mattress viewed from above the mattress whereby the head of the user rests on top of the mattress and the feet rest at the bottom of the mattress.
  • Figure 4 shows schematically a side view of a mattress manufactured according to the invention.
  • the reference numeral 1 denotes the mattress core
  • numeral 2 denotes the inserts
  • numeral 3 denotes the optional comfort layer
  • numeral 5 denotes the various body zones.
  • the next step in the method according to the invention is that on the basis of the deformation determined in the previous step, expressed in (a set of) deformation characteristics, a selection is made of inserts that correspond to the deformation as determined. This implies that the manufacturer or distributor of the mattresses manufactured according to the method of the present invention, holds an inventory of inserts that correspond to the various possible deformation characteristics.
  • the next step in the method according to the invention is that the selected inserts are positioned, fitted or placed upon the rest-side of the mattress core.
  • the inserts are positioned on the rest-side of the mattress core as follows:
  • the left and/or the right insert comprises at its inner side a transition zone, the deformation characteristic whereof, for example the hardness, is the average of the deformation characteristics, for example, the hardness of the left-, resp. rightinserts and the middle- insert. More generally, the hardness of this transition zone should be situated between the hardness of the left, resp. right- inserts and the middle insert. According to a more preferred embodiment, the hardness of such transition zone should be situated between 30 and 70 % of the average value mentioned above, still more preferably between 40 and 60 % of such average value.
  • the middle insert at one or both of its sides comprises one, resp. two transition zone (s) the deformation characteristic whereof, for example the hardness, is the average of the deformation characteristics, for example the hardness, of the middle- and the left-, resp. the right insert.
  • the deformation characteristic whereof, for example the hardness, is the average of the deformation characteristics, for example the hardness, of the middle- and the left-, resp. the right insert.
  • the hardness of this (these) transition zone(s) should be situated between the hardness of the left, resp. right- inserts and the middle insert. According to a more preferred embodiment, the hardness of such transition zone (s) should be situated between 30 and 70 % of the average value mentioned above, still more preferably between 40 and 60 % of such average value.
  • the width of such transition zone comprises in a preferred mode from 5 up to 15 cm, more preferably approx. 10 cm. More generally, the width of such transition zones are situated between 5 to 20 % of the width of the respective insert, more preferably between 7 to 15 %, still more preferably from 10 to 15 %.
  • comfort layer topper
  • rest side of the insert is the side whereupon the user rests.
  • the goal of this topper is to fade out possible unevenness in the global surface of the mattress (formed by the upper sides of the various inserts). Also, in the case of a two-persons bed, such comfort layer is often used to fade out unevenness at the transition point or zone between the mattress of the one person and the mattress of the other person.
  • a usual thickness for such comfort layer is for example 3 cm.
  • the thickness usually is comprised within 1 up to 7 cm, preferably between 2 up to 5 cm.
  • the mattress core and the inserts are held together by a case or sleeve, preferably a (extra) extensible case or sleeve that is positioned around the combination of mattress core and inserts.
  • the mattress core and the inserts comprise means that enable same to stick to each other in a flexible manner, for example by using Velcro's ® .
  • a sleeve to keep together the mattress core and the inserts is not required.
  • an anti-bacterial and washable resilient or flexible cover or sleeve Preferably use is made of an anti-bacterial and washable resilient or flexible cover or sleeve.
  • a sleeve is flexible but not too resilient to cover both the core and the inserts.
  • the invention relates to a mattress manufactured according to the method described above.
