This material may be any suitable ?lter material such as
nylon cloth or porous bronze.
The mattress is made to conform to a person’s body
by having the person lie or sit on the mattress or by
wrapping the mattress around the person and then by
evacuating the mattress to provide a formed support as

A further object of the invention is to provide a pro
tective formable bag construction which will act to dis
tribute an imposed force over a large area.
While certain speci?c embodiments have been described
in some detail, it is obvious that numerous changes may
be made without departing from the general principles

These and other objects will be more fully under
stood from the following detailed description taken with
the drawing wherein:
FIGURE 1 shows a formable mattress according to ‘
one embodiment of the invention;
FIGURE 2 is an enlarged partial cutaway end view
of the device of FIGURE 1;
FIGURE 3 shows the device of FIGURE 1 in its
formed condition;
and scope of the invention.
We claim:
1. A lightweight formable bag construction comprising,
a thin-walled hermetically sealed elastic container, said
container being ?lled with plastic microballon spheres, a
?uent material within said container in the space between
said plastic spheres, and means for evacuating said ?uent
material from said container, whereby said container
may be made to conform to a particular shape.

ing, a thin-walled hermetically sealed elastic container,
vices used for this purpose should be light weight and
should have structural resiliency which will act to at
tenuate the imposed force. A large quantity of plastic
bubbles, in the form of microballoon spheres, due to their
air content results in a very small weight.
These micro
balloon spheres due to their lightness and structural resil
iency provide attenuation of imposed forces.
