`In accordance with this invention the

`plurality of compartments by individual
`partitions which are, some or all of them,
`provided with means to allow of the slow
`- passage of air through the partition. The
`20 means may comprise small holes in the
`fabric of the partition or insertions of a
`material permeable to air, as for example,
`rubber, canvas or linen.
`
`In one way of carrying out this inven-
`tion as applied for example to a rubber
`cushion, the outer wall of the cushion is
`made
`of
`inextendable
`or
`extendable
`material,
`for example, canvas or linen,
`lined rubber or solid rubber.
`Theinterior of the cushion is divided
`into compartments by cross members of
`canvas or linen suitably coated to render
`it iinperviousgto air.
`The
`canvas, or
`linen,
`in some cases is provided with
`numerous small holes to allow the passage
`of air there through.
`In other cases it is
`provided with insertions of canvas or linen
`, or rubber permeable to air.
`The partitions may be attached to the
`cover by webs comprising several layers of

`type subdivided by partitions into_ a
`piurality of
`compartments _in which

`65 ti ions in the partitions
`
`for
`,of a material permeable to air, as,
`example, perforated rubber, canvas, or
`linen.
`The accompanying drawings illustrate
`various forms of device made in accord-

`'1.‘-he pa;1:titions.,cl are fer the purpose of
`maintaining; the shape of the cushion, and
`being pierced with small holes
`f, or
`having‘ insertions’ of canvas permeable to
`air, permit a slow passage of air from one

`
`The control of the air through these
`holes 3‘ or the canvas, prevents a sudden
`displacement which would
`cause
`the
`cushion to roll under pressure.
