Description
TECHNICAL FIELD
[0001] The invention relates to a mattress insert comprising
supporting blocks made of a foam material.
BACKGROUND ART
[0002] Mattresses are important constituents of the socalled
"sleeping systems" (articles related to sleeping).
Mattresses comprise a mattress insert that is usually covered
by a liner. A mattress insert is also called a mattress
core in the field of the art. In a mattress the role of the
mattress insert is to provide optimal weight distribution,
adequate load support, and an ergonomic sleep environment.
A number of different mattress types have become
widely used worldwide. These types vary greatly as far
as their manufacturing technology, structural configurations,
and technological constructions are concerned.
[0003] In the mattress insert according to US
5,604,021 two or three layers of different hardness are
laminated on top of one another. The hardness of a given
region of the mattress can be adjusted by differently selecting
the depth of grooves machined in the mattress
insert, as well as the choice of the materials applied for
the given layers.
[0004] In US 7,000,277 B2 a foam spring mattress
(comprising spring-shaped stubs, or in another words,
blocks) is disclosed, wherein the foam springs are separated
from each another by rectangular blocks also
made of foam material. The spring-shaped blocks and
the rectangular blocks arranged between them together
form a covering surface of even height.
[0005] In DE 10 2007 051 232 A1 a mattress formed
with foam springs is disclosed, wherein foam springs of
different width correspond to different regions of the mattress
surface.
[0006] In US 4,901,387 a mattress comprising foam
blocks is disclosed, wherein the height of the foam blocks
may be different at different (e.g. leg, waist, head) regions,
but the height is uniform within a given region.
Such an arrangement may provide different-height support
for different body regions. A similar solution is disclosed
in US 2011/0004998 A1, wherein surfaces of different
height may be formed, for instance for supporting
different body parts, by applying separate foam springs
inserted in a sheet. The foam springs are fixed into the
sheet adapted for joining the springs.
[0007] Foam blocks comprising spring portions and
homogeneous portions of different heights and forming
a load support surface of uniform height are disclosed in
US 7,496,981 B2, according to which a homogeneous
mattress material is disposed in a lower-thickness layer
above the taller foam blocks and in a higher-thickness
layer above the lower foam blocks.
[0008] A mattress having a layered configuration,
grooves, and blocks of uniform height, is disclosed in US
7,445,839 B2. In FR 2 220 238 a mattress insert provided
with diagonal grooves on a part of it is disclosed. A mattress
comprising foam blocks having multiple layers of
different density and firmness is disclosed in FR 2 539
297 and WO 2013/126972 A2. A common characteristics
of known mattress insert arrangements comprising multiple
layers having different density and firmness is that
the blocks comprising the layers have the same height
over the entire load surface of the mattress inserts, or for
instance over a continuous region thereof corresponding
to a given body region.
[0009] In US 4,768,251 a mattress arrangement comprising
foam blocks is disclosed wherein foam blocks of
different heights and shapes are arranged at different
regions of the mattress.
[0010] In US 4,397,053 a mattress is disclosed, wherein
recesses are formed in direction transverse to the direction
of elongation of the foam material body to increase
the flexibility of the mattress. Each recess extends
to one of the supporting surfaces; deeper recess portions
are connected to the supporting surfaces via a narrow
portion. When the mattress is loaded by a person, lips of
the mattress core structure lie on another portion of the
mattress core structure at this narrow portion.
[0011] In US 4,047,254 a mattress construction is disclosed.
The mattress construction comprises a top layer
with a plurality of projections. The top layer has a wavelike
structure similarly to the intermediate layer arranged
below the top layer.
[0012] In CN202112704 U, CN202234187 U and US
2011/0041252 A1 spring mattresses are disclosed
wherein a spring of greater height is surrounded by
springs having lower heights. Arrangements formed with
springs have the disadvantage that the springs cannot
be arranged with arbitrarily small spacings between
them; the manner in which the springs are arranged being
determined by the spatial extension of the springs. Thereby,
due to the application of springs, the load support
surface of such mattress inserts will have surface portions
- having a relatively large size with respect to the
cross sectional area of the springs - that are not supported
either by the taller or by the lower-height springs. This
disadvantage cannot be eliminated utilising solutions applying
springs.
[0013] A common disadvantage of several widely used
mattress types is that they are capable of providing sufficient
support only within an extremely restricted load
range, i.e. their support firmness is not dependent on the
load to which the mattress is subjected to. Known mattresses
are incapable of following the weight gains and
weight losses of the human body, and are also not capable
of providing a uniform support force for persons of
different weights. Thereby, they are incapable of providing
the same level of comfort for users of various weights.
[0014] A known mattress arrangement that provides
adequate support for a person weighing e.g. 75 kg is
incapable of adequately supporting and shape-following
the body of a person weighing 100 kg. This problem is

not solved even by mattress types comprising a uniform
structure but consisting of sections of different firmness
(ergonomic zones). Although these mattress types solve
the problem of following the shape of the body more accurately,
but are not capable of providing a supportive
reaction force that conforms to the needs of persons having
various body weights.
[0015] This problem occurs with all known mattress
types, such as mattresses comprising Bonnell springs,
foam mattresses, and pocket spring mattresses. Of these
mattress types, pocket spring mattresses may have highlevel
shape-following ability, but resulting from their uniform
structure (springs having homogeneous material)
they are not capable of responding to different loads with
differentiated reaction forces. This disadvantage is especially
conspicuous in case of the spring mattress inserts
according to CN202112704 U, CN202234187 U
and US 2011/0041252 A1 wherein the resistance of the
springs can only be adjusted by adjusting a spring constant
that is uniform along the entire length of the given
spring. The vast majority of known mattress solutions
have surface configurations wherein a single surface
plane is formed.
[0016] Based on the above reasoning it can be concluded
that known mattress inserts being spring-type or
not, are not capable of following any change in the mass
or weight distribution of the user’s body, and are also
incapable of fulfilling the requirements posed by the fact
that users have different builds and weights.
[0017] A further problem is posed in relation to known
mattresses. Mattresses are articles that are subjected to
very heavy use. Consequently, the support capability and
capability of even weight distribution of the mattresses
gradually deteriorate over the years due to the naturally
occurring structural changes and fatigue of their materials.
It has to be noted here that the average mattress
usage duration and replacement cycle time of households
is well over ten years. Taking into account the conditions
required for healthy sleep, the changes occurring
in a mattress insert due to structural fatigue over the average
replacement cycle time, and the mass and shape
changes the human body undergoes during that time, it
is clearly seen that the disadvantages of known mattresses
may appear already in a short period of time. Furthermore,
due to the reasons detailed above, a significant
deterioration of support and shape following capabilities
is inevitable in the long run, which, in addition to uncomfortable
sleep, may cause serious health, concentration,
and performance problems for the user.
[0018] In view of the known solutions, there is a demand
for a mattress insert that is capable of providing
even body support for persons having various body
weights.
DESCRIPTION OF THE INVENTION
[0019] The primary object of the invention is to provide
a mattress insert which is free of disadvantages of prior
art solutions to the greatest possible extent.
[0020] A further object of the invention is to provide a
mattress insert that is capable of providing uniform body
support for persons having various body weights.
[0021] The objects of the invention can be achieved
by the mattress insert according to claim 1. Preferred
embodiments of the invention are defined in the dependent
claims.

MODES FOR CARRYING OUT THE INVENTION
[0023] Fig. 1 shows an embodiment of the mattress
insert (in other words, mattress core) according to the
invention. The mattress insert according to the invention
comprises supporting blocks 10, 12, 14 made of a foam
material and arranged on a base body. The supporting
blocks 10, 12, 14 of the mattress insert according to the
invention are formed integrally with the base body, and
in the mattress insert according to the invention the supporting
blocks 10, 12, 14 comprise first supporting blocks
10 arranged with spacings from one another, and second
supporting blocks 12, 14 arranged in the spacings,
wherein a height of the second supporting blocks 12, 14
relative to the base body is lower than that of the first
supporting blocks 10. In the embodiment of Fig. 1 the
base body of the mattress insert is shown, whereon the
supporting blocks 10, 12, 14 are arranged.
[0024] The first supporting blocks 10 are arranged on
the base body spaced apart by spacings, and the second
supporting blocks 12, 14 are arranged in these spacings.
According to the illustrated embodiment, the second supporting
blocks 12 are arranged in the spacings in the rows

of the first supporting blocks 10 including an angle of 45°
with respect to the sides of the mattress insert, while the
second supporting blocks 14 are arranged in spacings
in the rows of the first supporting blocks 10 positioned
parallel with the edges of the mattress insert.
[0025] By the integrally-formed configuration of the
supporting blocks and the base body it is meant that the
supporting blocks and the base body are either made as
one piece, or the supporting blocks are secured to the
base body by adhesive bonding. As it is described below,
in the embodiment illustrated in the figures the base body
and the blocks are made as one piece, while adhesive
bonding is applied for securing together the layers of the
mattress.
[0026] According to the invention, the second supporting
blocks 12, 14, having lower height than the first supporting
blocks 10, are arranged in the spacings between
the first supporting blocks 10. The mattress insert according
to the invention is configured in such a way for
the following purpose: When the mattress insert is subjected
to lower loads, the weight of the body loading the
mattress is supported by the first supporting blocks 10
having larger height. In case of higher loads the higher
supporting blocks are compressed to an extent that the
second supporting blocks 12, 14 also come into play in
supporting the load. Since the supporting blocks applied
in the mattress insert according to the invention are made
of a foam material, the supporting blocks having lower
and larger height may be arranged arbitrarily by cutting
to size and shape the foam material of the mattress insert.
Furthermore, the spacings between individual first supporting
blocks, as well as the gaps between supporting
blocks of both types (first and second) may be set arbitrarily
thanks to the application of foam material. These
advantages do not occur in known mattress inserts
wherein higher and lower spring blocks are arranged beside
one another.
[0027] In the mattress insert according to the invention,
therefore, in case it is subjected to the loads of a person
having lower body mass only the higher first supporting
blocks support the loads, whereas both the higher first
supporting blocks and the lower second supporting
blocks take part in load support in case a person having
higher body mass is to be supported.
[0028] In the embodiment shown in Fig. 1 the mattress
insert comprises a sitting pad 16 arranged on the longer
side of thereof. The sitting pad 16 is homogeneous on
the entire height of the mattress insert. The arrangement
of the sitting pad 16 enables to have a sitting surface in
the region of the mattress insert where a user typically
sits down, since in case of a sitting user there is no need
to apply different supporting blocks that fit to the load and
"enter" as the load increases. The arrangement of the
sitting pad 16 does not affect the operation of the central
portion of the mattress insert that is typically applied for
load support. This is achieved by arranging the sitting
pad 16 as illustrated in the figure, i.e. the sitting pad may
extend into the surface of the mattress insert to a limited
extent only; whereas the dimension of the sitting pad
measured along the longer side of the mattress insert
may be chosen substantially arbitrarily.
[0029] The mattress insert according to the invention
comprises layers in the embodiment shown in Fig. 1;
these layers are identified in Fig. 2 by reference numerals.
In an embodiment, the mattress insert according to
the invention comprises a first layer 26, and a second
layer 24 made of a harder material than the first layer 26
and said second layer 24 is attached to the side of the
first layer 26 which faces the base body, wherein the first
layer 26 and the second layer 24 are arranged parallel
with the base body.
[0030] In the embodiment shown in Fig. 2 the invention
further comprises a third layer 22 made of a softer material
than the second layer 24 and arranged parallel with
the first layer 26 and the second layer 24, wherein the
third layer 22 comprises the base body.
[0031] The layers of the mattress insert according to
the invention are preferably made of a foam having a
density of 30-60 kg/m3. A foam material having lower
density (and lower manufacturing costs) than the material
of the first layer 26 and the second layer 24 may be applied
for making the third layer 22 that affects the comfort
of the mattress insert to a smaller extent than the first
and second layers. The first layer 26 and the second
layer 24 may have the same density; while the first layer
26 is softer than the second layer 24. The hardness of
the foam materials applied for making the first layer 26
and the second layer 24 may be compared applying e.g.
the CLD (compression load deflection) test method (http://www.sydney-heath.com/materials/polyurethanefoams/test-methods).
Other methods may also be applied
for comparing the hardness of the applied materials.
The second layer 24 is preferably at least 10% harder
than the first layer 26; our experiments indicate that a
differentiated reaction force (to be described in detail below)
may preferably be generated by this hardness difference.
Our experiments have also shown that the
present embodiment of the mattress according to the invention
is best suited for universal use - i.e. use by persons
of any body weight - in case the second layer 24 is
20-70% harder than the first layer 26. Measured applying
the CLD(25) method (cf. http://www.qualitvfoam.com/polyurethane-glossary.asp
and http://www.svdnev-heath.com/materials/polvurethanefoams/test-methods)
the hardness of the first layer 26 is
preferably between 25 and 50 kPa. The CLD(25) method
is characterised by that the sample of a given material is
subjected to a compression of 25% in the third phase of
the test measurement described in the referenced documents.
[0032] Therefore, the embodiment of the invention illustrated
in Fig. 2 has a three-layer configuration. In the
embodiment illustrated in the figures the ratio of the thicknesses
of the layers is 1:1:3 (first layer 26, second layer
24, and third layer 22), but other thickness values may
also be applied in the mattress insert according to the

invention.
[0033] The two- and three-layer arrangements described
above allow for generating a reaction force differentiated
according to the load as detailed below: The
topmost layer (according to the figures), which is located
farthest from the base body as shown in the figures, is
made of a softer foam material than the layer arranged
closer to the base body, i.e. the second layer that is situated
under the first layer according to the figures.
Thanks to this choice of materials the generated reaction
force gradually increases due to the elastic compression
of the higher first supporting blocks as the softer first layer
gets compressed to a greater extent. This reaction force,
which provides for support, is generated by applying load
to the mattress insert. The advantages related to the application
of multiple layers also cannot be achieved applying
a spring mattress insert, since the springs have
spring constants that remain the same along their entire
length.
[0034] In case the higher first supporting blocks are
compressed to an extent where the height of the compressed
first supporting blocks is the same as the height
of the second supporting blocks, the latter also start providing
support; and for compressions greater than this,
the support is provided by both the first supporting blocks
and the second supporting blocks.
[0035] Since in the present embodiment the material
of the second layer is harder than the material of the first
layer, the first layer is compressed more easily, while
greater loads are required for compressing the harder
second layer. Accordingly, (in case of lower loads) typically
the first layer gets compressed first, followed by the
second layer above a given load value. Naturally, the
harder second layer gets compressed to some extent
also in case of lower load forces, but for lower loads the
softer first layer plays the dominant role.
[0036] In an embodiment of the invention a side of the
second layer 24 which is the farther of the sides from the
base body is arranged farther from the base body than
90%, preferably 95%, of the height of the second supporting
blocks 12, 14 measured from the base body. Such
an embodiment is illustrated in Fig. 2. As shown in Fig.
2, the first layer 26 is only present at the topmost portion
of the second supporting blocks 12, 14. According to Fig.
2, therefore, a thin, softer-material layer is disposed at
the top of the supporting blocks 12, 14, but the portion
of the supporting blocks 12, 14 under this top part is made
of the harder material applied of the second layer 24.
Applying this configuration may provide that the "hardening"
of the mattress insert, i.e. the generation of higher
support forces occurs substantially only when the second
supporting blocks 12, 14 start to take part in providing
load support. The effect occurs substantially at this instance
because before that the very thin foam layer of
the material of the supporting blocks 12, 14 that belongs
to the first layer 26 has to be compressed. In other embodiments
the side of the second layer which is farther
from the base body is located higher than the height of
the second supporting blocks measured from the base
body, i.e. it is situated in the portion of the first supporting
blocks that extends above the second supporting blocks.
[0037] In the embodiment illustrated in Fig. 2 the mattress
insert also comprises the third layer 22 that is made
of a softer material than the second layer 24. The third
layer 22 also comprises the base body, i.e. the third layer
and the base body are made as one piece. For making
the third layer 22 it is preferred to select a material softer
than the second layer 24, as the third layer 22 has no
major role during the gradual assumption of load, the
significant deformations taking place in the first layer 26
and the second layer 24. The most significant role in providing
the gradually changing degree of support is played
by the portions of the first supporting blocks 10 and the
second supporting blocks 12, 14 lying in the first and
second layers 26, 24.
[0038] In the embodiment of the invention that is shown
in Fig. 2, the layers 22, 24, 26 are secured together by
adhesive bonding. The multilayer-configuration embodiments
of the mattress insert according to the invention
may be manufactured by adhesively joining foam sheets
made of the materials of the different layers (the sheets
may be bigger in size than the size of the mattress insert),
and then first cutting out the rectangular portions corresponding
to the individual mattress inserts, and subsequently
forming, by cutting the foam to shape (for instance
in a single stage, in two directions), the first supporting
blocks and the second supporting blocks of the
individual mattress inserts. According to the above, the
multi-layer embodiments comprise two or more layers,
but further layers may also be arranged.
[0039] As it is shown in Figs. 1 and 2, the second supporting
blocks 12, 14 are arranged in the spacings spaced
apart from the first blocks 10 with a first gap. The first
gap is the gap separating the first supporting blocks 10
from the second supporting blocks 12, 14. In the embodiment
illustrated in the figures each first supporting block
10 is preferably surrounded by eight second supporting
blocks 12, 14, and the second supporting blocks are
spaced apart from one another with a second gap. The
first gaps and the second gaps preferably ensure that
the first supporting blocks 10 and second supporting
blocks 12, 14 may be compressed independently of one
another. The supporting blocks 10, 12, 14 may protrude
sideways as they are compressed. These protrusions
occurring under load may be accommodated in the gaps.
[0040] The mattress insert according to the invention
may have such embodiments wherein the first supporting
blocks and the second supporting blocks are not separated
by a gap. In this case, the independent compressibility
of the blocks may for instance be provided by separating
(cutting) the supporting blocks from one another
down to the base body.
[0041] The base body preferably ensures the required
movement of the supporting blocks connecting to it, and
the required stiffness of the mattress insert. In case an
overly thin base body is applied, the supporting blocks

would be able to move completely freely independent of
one another, and therefore, for the supporting blocks to
perform their role adequately it is expedient to utilise a
base body that is thicker than a certain minimum thickness.
As shown also in the figures the thickness of the
base body is expediently at least 30%, particularly preferably
at least 50%, of the height (i.e. the dimension perpendicular
to the base body) of the first supporting blocks.
The thickness of the base body is also affected by the
desired application: above a certain thickness the thickness
of the applied base body may be arbitrarily large.
In addition to increasing the thickness of the base body,
the adequate movement of the supporting blocks and the
required stiffness of the mattress insert may be provided
for in other manners.
[0042] In the embodiment illustrated in Figs. 1 and 2
the size of the first supporting blocks 10 in a direction
parallel with the base body is at least twice the size of
the spacing. This condition may be fulfilled by applying
supporting blocks of any (e.g. circular) cross-sectional
shape. In an embodiment of the invention the cross section
of the supporting blocks 10, 12, 14 taken in a direction
parallel with the base body is rectangular. Furthermore,
in the embodiment shown in Figs. 1 and 2 the cross section
of the first supporting blocks 10 taken parallel with
the base body is square in shape, and each first supporting
block 10 is surrounded by four rectangular cross-section
second supporting blocks 12 arranged along its sides
and four square cross-section second supporting blocks
14 arranged near its corners.
[0043] This arrangement of the second supporting
blocks 12, 14 around the square cross-section first supporting
block 10 is preferred because thereby the second
supporting blocks 12, 14 are arranged in a regular manner
around the first supporting blocks 10, and, thanks to
the manner in which the second gaps are arranged the
second supporting blocks 12, 14 may also be displaced
with respect to one another.
[0044] Arranging the first supporting blocks and the
second supporting blocks according to the above condition
preferably allows that the wider first supporting
blocks applied in such embodiments - which assume the
load in case of lower load values - provide a significantly
larger surface area with their top sides than the second
supporting blocks "helping" in case of higher load values.
Thereby the load is distributed more evenly on the higher
first supporting blocks, and the second supporting blocks
start providing support only in case of higher load values.
It is at the same time more expedient to cover with the
softer-material first supporting blocks a greater portion
of the loaded side of the mattress insert, since the soft
blocks may thus provide a more even support surface.
This large surface portion is "complemented" by the
"helping" second supporting blocks in case at certain regions
of the large surface portion that are subjected to
higher loads the higher first supporting blocks are compressed
to a sufficient extent.
[0045] In an embodiment of the invention at least the
portion of the first supporting blocks 10 extending beyond
the second supporting blocks 12, 14 with respect to the
base body has a bellows-like shape having a longitudinal
axis perpendicular to the base body. In the embodiment
illustrated in the figure, preferably only the portion of the
first supporting blocks 10 extending beyond the second
supporting blocks 12, 14 has a bellows-like shape, since
it is this portion that undergoes the largest deformation
under load (it is compressed when subjected to a very
wide range of possible loads, but can withstand loads in
case of only very small loads). The bellows-like configuration
provides for adequate flexibility and dynamics.
[0046] The mattress insert according to the invention
is illustrated in Fig. 3 in such a way that it is provided with
a load distribution layer 18 arranged on the side opposite
the base body, where the load distribution layer is supported
on a plane defined by top parts of the first supporting
blocks 10. Also, as shown in Fig. 3, the mattress
insert covered by the load distribution layer 18 is covered
with a liner 20. The load distribution layer 18 is adapted
for spreading the load to which the mattress insert is subjected
across the loaded side of the insert. In use, the
mattress comprising the mattress insert typically bears
the load of a person’s body lying thereon. The human
body subjects different portions of the mattress insert to
different loads. Thus, by the inclusion of the load distribution
layer 18 it may be provided that this load is distributed
over more blocks than in the case where the
mattress insert is applied without a load distribution layer
18. In which latter case the use of the mattress insert
would also be less comfortable.
[0047] By distributing the load over more supporting
blocks the mattress insert according to the invention operate
more effectively, since by the application of the load
distribution layer 18 the body is supported over an increased
surface area, with the blocks of the same height
behaving substantially the same way, and - because of
the improved load distribution - with the lower-height second
supporting blocks "entering" only when higher loads
are present.
[0048] In an embodiment of the invention the second
supporting blocks 12, 14 have a height that is lower than
the height of the first supporting blocks 10 by 0.5 to 5 cm,
preferably by 1 to 3 cm, and particularly preferably by 1
to 2 cm. Our experiments carried out during the development
of the mattress insert according to the invention
have shown that for height differences under 0.5 cm the
smooth, gradualness of load assumption between the
first and second supporting blocks becomes hindered as
load is gradually increased, since the second supporting
blocks start operating already at lower load values. It is
not preferred to apply height differences above 5 cm, as
such height differences cannot be effectively bridged
even by applying a load distribution layer 18 for optimal
surface comfort. The height difference between the
blocks is preferably at least 1 cm, above which the mattress
insert is capable of responding to loads in a relatively
wide range. Applying a load distribution layer 18,

height differences up to 3 cm may be bridged so that the
inhomogeneities of the resulting mattress surface
caused by the top portions of the first supporting blocks
10 are not felt as a disturbance by the user. The preferred
height difference range to be applied is 1-2 cm. According
to our experiments, the range of loadability is widest and
the comfort of the mattress is best in case the height
difference is within this range. These height difference
values are for a normal-sized mattress insert, to be used
by adults.
[0049] Figs. 4 and 5 show a top plan view of the embodiment
of the inventive mattress insert illustrated in the
previous figures before cutting out the portion belonging
to the sitting pad 16 (Fig. 4: the cutting contour of the
sitting pad 16 is shown), and after adhesive joining the
sitting pad 16 (Fig. 5: the homogeneous configuration of
the sitting pad 16 is shown).
[0050] The pattern formed on the load bearing surface
of the mattress insert by the first supporting blocks 10
and the second supporting blocks 12, 14 is shown especially
clearly in Figs. 4, 5. The pattern formed by the
blocks 10, 12, 14 does not necessarily extend over the
entire load supporting surface, it may be omitted for example
near the corners of the mattress inserts.
[0051] According to the present embodiment the
blocks 10, 12, 14 are formed by making cuts at an angle
of 45° with respect to the sides of the rectangular mattress
insert (the bellows-shaped top portion of the first supporting
blocks 10 may be formed by making further cuts).
The supporting blocks may also be formed by making
cuts at an angle of 90° or at any other angle with respect
to the sides of the mattress insert. The shape of the pattern
at its edges is of no major importance; the pattern
may be terminated in any manner as determined by the
exact dimensions of the mattress insert.
[0052] In Fig. 6 the embodiment illustrated in the previous
figures is shown cut along a row of the first supporting
blocks 10. As shown also in this figure, the second
layer 24 preferably extends along the whole mattress insert,
between the first layer 26 and the third layer 22. It
is also clearly shown that, in addition to the top portions
of the first supporting blocks 10, a thin layer disposed on
the top portions of the supporting blocks 12 is also part
of the first layer 26. Fig. 7 shows a side view of the mattress
insert cut along the line shown in Fig. 6. The figure
illustrates clearly the multilayer structure of the present
embodiment of the mattress insert, as well as the relative
positions of the individual layers 22, 24, 26 inside the
mattress insert. It is also shown that the bottom portions
of the blocks and the base body are made from one piece.
[0053] The embodiment of the mattress insert illustrated
in the previous figures is shown next along a cut made
at an angle of 45° with respect to the direction of the cut
illustrated in Fig. 6. According to this figure, the mattress
insert is cut along a diagonal of the top sides of the first
supporting blocks 10 and the top sides of the supporting
blocks 14. The multilayer configuration is shown also in
this figure.
[0054] Fig. 9 shows a detail of Fig. 1. In this detail the
edge of the mattress insert according to the present embodiment
is shown. The view shown in the figure clearly
illustrates the structural configuration of the blocks 10,
12, 14. In Fig. 10 the above described embodiment of
the mattress insert is illustrated by a view along the cut
according to Fig. 6; the layer structure of the mattress
insert and the gaps formed between the supporting
blocks 10 and 12 are clearly shown in this figure. In the
illustrated embodiment the base body is also defined by
the gaps between the supporting blocks 10, 12, 14; the
gaps extend downward as far as the top side of the base
body.
[0055] Supporting blocks are alternatively called
shape-cut units.
[0056] Ergonomic zones are sections formed on the
mattress or inside the mattress insert, the zones being
arranged lengthwise (in the lying direction) and extending
along the entire width of the mattress insert. In known
mattresses, ergonomic zones are adapted for facilitating
the following of uneven body weight distribution and the
ergonomic adaptation to the shape of the body by the
mattress insert. The different ergonomic zones are subjected
to different loads, and therefore some ergonomic
zones are made of harder, while others are made of softer
materials. Mattresses are subjected to the greatest load
at the waist region. Accordingly, some known mattresses
are reinforced in the waist region of the mattress in some
way, for instance by including a stronger, thicker, largerdiameter
spring, or by including transversal profiles (typically
2-5 cm-wide strips) usually made of foam or coconut
fibre. The fundamental disadvantage of these known solutions
is that they are not capable of providing the same
level of comfort for users of different body structures.
They respond differently to the loads posed by a person
weighing 100 kg who is 200 cm tall, and by a person who
also weighs 100 kg but is only 150 cm tall. Supporting
the weight of a taller person who is not heavy at the waist
region requires smaller reaction forces than supporting
the weight of a waist-heavy person (e.g. a person 150
cm tall weighing 100 kg).
[0057] The mattress insert according to the invention
also eliminates this disadvantage, since due to its configuration
a reaction force exactly corresponding to the
load of the body lying thereon is generated, for instance
at the waist region (and at all other differently loaded
regions). In the mattress insert according to the invention
the first and second supporting blocks are compressed
in all regions of the load-bearing surface to an extent
corresponding to the load the given region is subjected
to. Thereby, the mattress insert according to the invention
may behave in such a way that in a region subjected to
higher load the first supporting blocks are compressed
to such an extent that they reach the level of the second
supporting blocks, and thus the second supporting blocks
also take part in providing the support force, while in other,
lower-load regions support is provided only by the first
supporting blocks, and therefore different support forces

are provided in the different regions.
[0058] Considering the above mentioned example, the
mattress insert according to the invention provides lower
support force in the same region for supporting the waist
of a person 100 kg/200 cm than for supporting the waist
of a person of 100 kg/150 cm. The same principle is also
applicable to the case involving two persons with different
weights - 60 kg and 120 kg -, since for the lower-weight
person only such an amount of reaction force is provided
at the waist region that is necessary but not uncomfortable,
whereas for the person weighing 120 kg a much
larger support force is provided by the mattress insert at
the waist region.
[0059] A further advantage of the mattress insert according
to the invention is related to the fact that although
the waist region is located in a given interval for different
body shapes and heights, shoulder regions may be situated
differently. There exist a number of known solutions
comprising shoulder regions (fitted to body heights)
corresponding to these requirements, but these are usually
manufactured to order, and cannot follow the changes
of the body. The mattress insert according to the invention,
however, is capable of following the changes of
the body, as well as of fulfilling the requirements posed
by different body heights, since - as it is illustrated in the
figures - the load-bearing surface preferably has a homogeneous
configuration. Therefore, the mattress insert
according to the invention does not have ergonomic
zones, because due to the inclusion of the supporting
blocks adapting to the shape of the body ergonomic
zones are not required. The mattress insert according to
the invention provides load support over the entire loadbearing
surface that is suited to the user’s body shape
and other needs.
[0060] The invention is, of course, not limited to the
preferred embodiments described in details above, but
further variants, modifications and developments are
possible within the scope of protection determined by the
claims.
