FIELD OF INVENTION
[0001] The present invention relates to a body support structure.
[0002] More particularly, the invention relates to a body support structure which includes
a panel of resilient, compressible material, the panel having longitudinal sides,
a top end and a bottom end.
BACKGROUND TO INVENTION
[0003] The conventional type of mattress or back rest does not provide sufficient comfort
to persons suffering from lumbago pains and other back problems when lying thereon
or when backresting against it.
[0004] It is an object of the invention to suggest an improved body support structure, preferably
in the form of a mattress or back abutting structure or member, which will assist
in providing comfort when lying thereon or when backresting against it.
SUMMARY OF INVENTION
[0005] The object in accordance with the invention is obtained by means of a body support
structure as defined in the characterizing part of claim 1.
[0006] Further advantageous embodiments of the invention are set out in the subsidiary claims.
BRIEF DESCRIPTION OF DRAWINGS
[0007] The invention will now be described by way of example with reference to the accompanying
schematic drawings.
[0008] In the drawings there is shown in:

the invention;
FIGURE 2 a side view seen along arrow II in Figure 1;
FIGURE 3 an end view seen from the head end of the mattress along arrow III in Figure 2;
FIGURE 4 an end view seen from the foot end of the mattress along arrow IV in Figure 2;
FIGURE 5 a sectional end view seen along arrows V - V in Figure 1; and
FIGURE 6 on an enlarged scale, a sectional view of part of the upper resilient layer seen

DETAILED DESCRIPTION OF DRAWINGS
[0009] Referring to the drawings, the body support structure, generally indicated by reference
numeral 10, is in the form of a mattress.
[0010] It includes a rectangular base panel 12 made of resilient material and having longitudinal
sides 14 and 16, a top end 18 and a bottom end 20.
[0011] Below the upper end of the panel 12 extending from the top end 18 a wedged shaped
head part 22 is provided. As shown it narrows from the top end 18 towards the bottom
end 20.
[0012] A neck support ridge 24 is provided on top of the panel 12 near the head end 18 to
extend transversely across the panel 12. It is curved along its upper side as can
be seen in Figure 2.
[0013] Two waist side members or ridges 26, 28 are provided respectively along the opposite
longitudinal sides 14, 16. They are curved seen in end view to be of substantially
semi-circular shape as can be seen in Figures 3 and 4.
[0014] A back support layer 30 is provided extending between the ridges 26 and 28. It has
two side flaps 32, 34 between which and the ridges 26, 28 side support parts 36, 38
are provided (see also Figure 5). These side support parts 36, 38 preferably are constructed
of three superimposed layers of different resiliency and density foam material, the
softer layer being on top.
[0015] The total upper surface of the mattress 10 is covered by means of a resilient layer
40. The layer is indicated in dotted lines in Figure 2 at the bottom part of the mattress
but for clarity sake is left out in the remainder of the drawings. This layer 40 is
made of resilient low density material, which is less soft than the material of the
other layers.
[0016] The undulating surface of the upper layer 40 as shown enlarged in Figure 6 assists
in providing ventilation paths when a person lies thereon and also a proper pressure
distribution.
[0017] The structure of the mattress 10 is specifically designed to provide a comfortable
support to the body of a person, in particular in the lumbar regions of the body and
thereby to assist in relieving lumbago pains, that is muscular pains in the lumbar
region.
[0018] Although the structure is shown to be in the form of a mattress 10 it also can be
shorter so serve as back support placed against the back rest part of a chair or of
a motor car seat. In such a case the length of the body between the top end 20 and
the bottom end 18 will be considerably reduced and will not include the part indicated
by reference numeral 42 in Figure 1.
[0019] The different layers may be heat sealed or fused together, e.g. along the borders.
1. A body support structure for supporting a person when lying thereon or abutting against
it, including a panel (12) of resilient, compressible material, the panel (12) having
longitudinal sides (14, 16), a top end (18) and a bottom end (20);
characterized thereby that it includes
a) a wedge shaped head end part (22) extending substantially from the top end (18)
of the panel (12) towards the bottom end (20) of the panel, the head end part narrowing
in thickness from the top end (18) of the panel towards the bottom end (20) of the
panel;
b) a neck rest part (24) extending substantially transversely across the panel (12)
near the top end (18) of the panel, the neck rest part (24) being curved along its
upper surface seen in side view;
c) two elongated waist side members (26, 28) extending along the opposite longitudinal
sides (14, 16) of the panel, the waist side members (26, 28) being curved along their
upper surface seen in end view; and
d) a back rest part (30) being made of resilient material and extending between the
waist side members (26, 28).
2. A structure as claimed in claim 1, characterized thereby that it is in the form of
a mattress (10).
3. A structure as claimed in claim 1, characterized thereby that it is in the form of
a back support for a chair.
4. A structure as claimed in claim 1, characterized thereby that it is in the form of
a back support for a vehicle seat back rest.
5. A structure as claimed in any one of the preceding claims, in which side support parts
(36, 38) are provided on the waist side members (26, 28), these side support parts
(36, 38) being constituted by various superimposed layers of foam material having
different resiliencies.
6. A structure as claimed in any one of the preceding claims, characterized thereby that
the panel (12), the back rest part (22), the side members (26, 28) and the back rest
part (30) are covered by means of a surface layer (40) of resilient soft material.
7. A structure as claimed in claim 6, characterized thereby that the surface layer (40)
is constituted by undulations in the form of alternating cups and caps.
