Abstract

A shock-absorbing cushion comprising two sheets peripherally sealed and a plurality of half-through holes and/or grooves whose circumferential walls constitute a cubic supporting structure shock-absorbing cushion has a hollow interior possible to be filled with air, gas, liquid or semi solid to change its inner pressure, and is able to be combined with one another to be applied to sports goods, shoe soles, etc., for protecting something from pressure or shock.

Claims

1. A cushion device comprising:

a cushion having two superimposed synthetic flat plastic sheets peripherally continuous at its edges and bounding an interior space filled with fluid, a plurality of recesses formed in one of said sheets each recess being bounded by walls extending from said one of said sheets in an inward direction towards the other of said sheets and extending to and being sealed with the other of said sheets at a continuously flat surface of the other of said sheets, said walls subdividing the interior space into separate compartments, and said walls including portions which are spaced from said other of said sheets to provide fluid flow openings between the compartments, and

an outer bag surrounding said cushion for protections of said cushion.

2. A cushion device as claimed in claim 1, wherein said outer bag is made of a transparent material.

3. A cushion device as claimed in claim 1, wherein said outer bag is made of an opaque material.

4. A cushion device as claimed in claim 1, wherein said outer bag is made of a flexible material.

5. A cushion device as claimed in claim 1, wherein said outer bag is made of an elastic material.

6. A cushion device as claimed in claim 1, wherein said outer bag is made of a foamable material.

7. A cushion device as claimed in claim 1, wherein said outer bag includes openings.

8. A cushion device as claimed in claim 1, wherein said recesses are full of a material.

9. A cushion device comprising:

a cushion including a single continuous synthetic piece of plastic having two superimposed flat sides peripherally continuous at its edges and bounding an interior space filled with fluid, a plurality of recesses formed in one of said sides each recess being bounded by walls extending from said one of said sides in a direction into the interior space towards the other of said sides and extending to and being sealed with the other of said sides at a continuously flat surface of the other of said sides, said walls subdividing the interior space into separate compartments, and said walls including portions which are spaced from said other of said sheets to provide fluid flow openings between the compartments, and

an outer bag surrounding said cushion for protection of said cushion.

10. A cushion device as claimed in claim 9, wherein said outer bag is made of a transparent material.

11. A cushion device as claimed in claim 9, wherein said outer bag is made of an opaque material.

12. A cushion device as claimed in claim 9, wherein said outer bag is made of a flexible material.

13. A cushion device as claimed in claim 9, wherein said outer bag is made of an elastic material.

14. A cushion device as claimed in claim 9, wherein said outer bag is made of a foamable material.

15. A cushion device as claimed in claim 9, wherein said outer bag includes openings.

16. A cushion device as claimed in claim 9, wherein said recesses are full of a material.
