The ends of the cylindrical inflatable cells are inclined and press against opposite inclined sides of the groove, while the other two opposite sides of the groove are straight.
Disclosure of Invention
In particular, the invention proposes a support device in which the risk of deformation and separation of the constituent elements is reduced.
An embodiment proposes a support device for supporting a body or a part of a body, in particular a human body, comprising: a support element made of a deformable material and comprising a seat and a peripheral side wall projecting from one side of a top surface of the seat so as to define a recess having a top and a peripheral side; and a pneumatic element comprising a base and a plurality of inflatable cells protruding from one side of the base and positioned adjacent to each other in a grid pattern of lines and columns, the inflatable cells being embedded in the recess and extending between a top of the recess and the base of the pneumatic element.
The peripheral side wall of the support element comprises at least one retaining bead projecting inwards, positioned at a distance from the top of the groove, so that the peripheral side of the groove has at least one blocking portion, at least some of the inflation cells adjacent to said retaining bead being able to engage laterally between the retaining bead and the top of the groove when inflated, and being able to retain the pneumatic element along the periphery or perimeter of the groove.
The retaining bead may comprise partial portions extending over partial lengths of the peripheral sides of the groove, respectively.
The retaining bead may extend over the entire length of the peripheral side of the groove.
The base of the pneumatic element may have an edge extending over the end face of the peripheral side wall of the support element.
The pneumatic element may comprise at least one duct connected to the at least one inflatable cell and passing through the peripheral side wall of the support element.
A lower support plate made of a deformable material may be provided so as to cover the base of the pneumatic element and the end faces of the peripheral side walls of the support element.
The device may also include a housing.
Drawings
Following is a non-limiting exemplary description of a support apparatus, illustrated by way of example in the accompanying drawings, wherein:
figure 1 shows a cross-section of the support device including the pneumatic element in a deflated condition;
FIG. 2 shows a cross-sectional view of the support device of FIG. 1 with the pneumatic element in a positive inflation state; and
fig. 3 shows a partially enlarged cross-sectional view of the pneumatic element.
Detailed Description
As shown in fig. 1,2, a substantially parallelepiped support device 1, which may constitute, for example, a seat cushion for sitting thereon, comprises a support element 2 made of a deformable material, such as moulded synthetic foam (polyurethane foam), the support element 2 comprising a horizontal seat 3 in the form of a top surface and a peripheral side wall 4 projecting downwards from the periphery of the seat 3, so that the support element 2 defines a hollow recess 5 open below. The groove 5 has a top 6 consisting of the lower surface of the seat 3 and a peripheral or lateral surface 7 consisting of the inner lateral surface of the peripheral side wall 4.
The upper surface of the seat 3 of the support element 2 may be flat or uneven and have a desired shape. The top 6 of the groove 5 may be flat. The peripheral outer surface of the peripheral side wall 4 may extend perpendicularly to the upper surface of the seat 3.
The peripheral side wall 4 comprises a peripheral retaining bead (8) projecting towards the inside of the groove 5 and located at a distance from the top 6, so that the periphery or side 7 of the groove 5 has an obstructing peripheral portion 7a, which extends between the peripheral retaining bead 8 and the top 6 of the groove 5 and has a greater portion than the inside of the peripheral retaining bead 8.
The support device 1 further comprises: a pneumatic element 9 comprising a substantially flat and relatively rigid base 10, which is placed parallel to the top of the groove 5 and the peripheral edge 10a of the base 10 is pressed against the lower end face 4a of the peripheral side wall 4, parallel to the top 6 of the groove 5; and a plurality of inflatable cells 11 projecting upward from the base 10 side and adjacent to each other such that the inflatable cells 11 are engaged inside the groove 5 and extend between the base 10 and the top 6 of the groove 5.
The inflatable cells 11 are connected to each other by means of a small-cross-section connecting channel 12 incorporated in the base 10, while each of the peripheral inflatable cells 11a is connected to a duct 13, which duct 13 passes through the peripheral side wall 4 of the support element 2 and is provided, for example, with an outer end valve 14 to which inflation/deflation means (not shown) can be connected.
For example, the gas cells 11 are arranged in a grid of lines and columns perpendicular to each other. The inflatable cells 11 may be arranged in an offset pattern.
As shown in fig. 3, the base 10 of the pneumatic element 9 may comprise a first flat plate 15 and a plate 16, the plate 16 having areas of adhesion to the plate 15 and protruding deformations in these areas, which define the inflation cells 11 and the connection channels 12.
As shown in fig. 1, 3, when the pneumatic element 9 is deflated, the inflation cell 11 occupies less space. In this deflated state, the cross-section of the inflatable cells 11 may be circular or polygonal, e.g., hexagonal, and their bottoms adjacent the base 10 are remote from each other.
In the deflated condition, the pneumatic element 9 is easily fitted into the groove 5 of the support element 2 by passing the inflation cell 11 through the inner portion of the retaining bead 8, without difficulty.
When the pneumatic element 9 is inflated, the inflatable cells 11 expand laterally along a generatrix perpendicular to the base 10 and abut against each other and against the neck 6 of the groove 5, as shown in figure 2.
Furthermore, the peripheral pneumatic unit 11a of the pneumatic element 9 adjacent to the retaining bead 8 (adjacent to the retaining bead) engages transversely to the peripheral obstacle arranged between the inner retaining bead 8 and the top 6 of the groove 5 and can press the obstacle portion 7a of the peripheral side wall 7 of the groove 5. Thus, the circumference of the pneumatic element 9 is kept along the circumference of the groove 5.
When inflated, the pneumatic element 9 occupies all or part of the volume of the recess 5 of the support element 2, depending on the pressure of the introduced gas, and the pneumatic element 9 forms a coherent pneumatic support by the inflation cells pressing against each other and the peripheral inflation cells pressing against the obstruction 7 a.
In contrast to the straight side, in the inflated condition, the peripheral inner retaining bead 8 presents an obstacle along the periphery of the groove 5 for the peripheral inflation cells 11a of the pneumatic element 9 and for the extraction of the entire pneumatic element 9.
The presence of the peripheral internal retaining bead 8 therefore prevents the extraction of the pneumatic element 9 inflated from the groove 5 of the support element 2.
Alternatively, the support device 1 may comprise: a lower support plate 17 made of a deformable material, for example synthetic foam, such as polyurethane foam, the lower support plate 17 covering the base 10 of the pneumatic element 9 and the lower surface 4a of the peripheral wall 4 of the support element 2, sandwiching the peripheral edge 10a of the base 10. According to a variant embodiment, the peripheral edge 10a of the base 10 and/or the lower plate 17 can be adhesively bonded to the lower surface 4a of the peripheral side wall 4 of the support element 2.
The support device 1 may also comprise a two-part housing 18, which is connected together by a peripheral snap lock 19, and the pipe 13 also passes through the housing 18. The housing may be a fabric, which may be a waterproof material.
The result of the above is that the support device 1 constitutes a compact and coherent apparatus, the components of which are easy to install.
According to a variant embodiment, the inflation cells 11 of the pneumatic element 9 can be grouped into a plurality of independent groups, each connected to a different inflation duct 13, so as to define regions inflatable to different pressures.
According to a variant embodiment, the peripheral retaining bead 8 may extend around the entire perimeter of the groove 5 of the support element 2.
According to another variant embodiment, the peripheral retaining bead 8 may comprise partial portions extending over four edge portions forming the perimeter of the groove 5 of the support element 2.
According to another variant embodiment, the peripheral retaining beads 8 may be arranged at different distances from the top 6 of the groove 5 of the support element 2.
According to a variant embodiment, the support device 1 may comprise a plurality of identical recesses 5 for receiving identical pneumatic elements 9.
For example, the structure of the support device described above may be varied to constitute a mattress, a back support or a tool for positioning or fixing a body.
