Abstract
Abstract Air encapsulating cellular material in which failure due to the rupture of individual ones of the cells thereof is substantially prevented. The material comprises a sheet defining a plurality of air encapsulating cells in a substantially uniform pattern. At least a pair of adjacent cells are in flow communication so that upon direct pressure to one of such cells, the air may be displaced and can flow to the adjacent cell. In this manner, air pressure build up in one cell which may otherwise have resulted in its rupture, is prevented.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
129 words
Interactive air encapsulating cellular material comprising: first and second sheets of flexible, substantially air impervious material, said first and second sheets being joined together in a pattern to form a plurality of air encapsulating cells in a substantially uniform pattern; a plurality of chambers defined by said first and second sheets, said chambers extending between adjacent cells respectively and open at each end thereof into said cells for establishing an air flow passage between at least a pair of adjacent cells so that air may be displaced from one of such cells to the other in order to prevent rupture of such one cell; and means associated with at least one cell of adjacent cells connected by said chambers for selectively enabling said cells to be inflated and deflated.
Claim 2
Dependent Claim
129 words
Interactive air encapsulating cellular material comprising: first and second sheets of flexible, substantially air impervious material, said first and second sheets being joined together in a pattern to form a plurality of air encapsulating cells in a substantially uniform pattern; a plurality of chambers defined by said first and second sheets, said chambers extending between adjacent cells respectively and open at each end thereof into said cells for establishing an air flow passage between at least a pair of adjacent cells so that air may be displaced from one of such cells to the other in order to prevent rupture of such one cell; and means associated with at least one cell of adjacent cells connected by said chambers for selectively enabling said cells to be inflated and deflated.
Claim 3
Dependent Claim
16 words
The invention of claim 1 wherein said air encapsulating cells are aligned in substantially parallel rows.
Claim 4
Dependent Claim
15 words
The invention of claim 1 wherein said chamber interconnects substantially all cells in a row.
Claim 5
Dependent Claim
13 words
The invention of claim 1 wherein said chamber interconnects cells in adjacent rows.
