Pneumatic cushioning material

Abstract

A pneumatic cushioning material includes: a first air cell part including at least one air cell containing air; a second air cell part including at least one air cell containing air; a third air cell part including at least one air cell containing air; a first connection that connects the first air cell part and the second air cell part together; a second connection that connects the first air cell part and the third air cell part together, wherein the first connection is bendable by a first rotation axis, the second connection is bendable by a second rotation axis, and an angle at which a line segment obtained by extending the first rotation axis and a line segment obtained by extending the second rotation axis intersect is at a range of greater than 0 degrees and less than 180 degrees.

What is claimed is: 
     
         1 . A pneumatic cushioning material comprising:
 a first air cell part including at least one air cell containing air;   a second air cell part including, at least one air cell containing air;   a third air cell part including at least one air cell containing air;   a first connection that connects the first air cell part and the second air cell part together;   a second connection that connects the first air cell part and the third air cell part together, wherein   the first connection is bendable by a first rotation axis,   the second connection is bendable by a second rotation axis, and   an angle at which a line segment obtained by extending the first rotation axis and a line segment obtained by extending the second rotation axis intersect is in a range of greater than 0 degrees and less than 180 degrees.   
     
     
         2 . The pneumatic cushioning material according to  claim 1 , wherein the angle at which the line segment obtained by extending the first rotation axis and the line segment obtained by extending the second rotation axis intersect is approximately 90 degrees. 
     
     
         3 . The pneumatic cushioning material according to  claim 1 , further comprising a first coupling that couples the second air cell part and the third air cell part together when the first connection and the second connection each are bent. 
     
     
         4 . The pneumatic cushioning material according to  claim 3 , wherein the first coupling includes a claw part on any one of the second air cell part or the third air cell part, and includes, on another of the second air cell part or the third air cell part, any one of a hole part, a notch part, or a claw part that engages with the claw part on the one. 
     
     
         5 . The pneumatic cushioning material according to  claim 3 , wherein the first coupling includes a bendable sheet piece in any one of the second air cell part or the third air cell part. 
     
     
         6 . The pneumatic cushioning material according to claim further comprising a second coupling that couples separated parts together when there are the separated parts between the first air cell part and the second air cell part, and between the first air cell part and the third air cell part. 
     
     
         7 . The pneumatic cushioning material according to  claim 6 , wherein the second coupling includes a claw part on one of the separated parts, and includes, on another of separated parts, any one of a hole part, a notch part, or a claw part that engages with the claw part on the one.
