Abstract

A fastening assembly and a cushion having the same are provided. The fastening assembly includes a first strip and a second strip. The first strip has a first surface protrudingly provided with a plurality of hooks, and a second surface to which the second strip is bonded. The fastening assembly further includes a first protective layer and a second protective layer, both comprising a magnetic substance. The first protective layer is disposed lengthwise along both lateral sides of the first surface of the first strip so as to form sidewalls respectively and embed some of the hooks. The second protective layer is attached to the first protective layer so as to cover the hooks on the first surface of the first strip.

Claims

1. A fastening assembly, comprising a first strip having a first surface and a second surface, the first surface being protrudingly provided with a plurality of hooks, the fastening assembly being characterized by further comprising:

a first protective layer comprising a magnetic substance and provided lengthwise along two lateral sides of the first surface of the first strip so as to form sidewalls respectively and embed some of the hooks;

a second protective layer comprising the magnetic substance, wherein the second protective layer is attached to the first protective layer so as to cover the hooks of the first surface; and

a second strip attached to the second surface of the first strip.

2. The fastening assembly of claim 1, wherein the second protective layer has a surface facing the first strip and provided with a plurality of fastening structures for engaging with the hooks.

3. The fastening assembly of claim 1, wherein the second strip is made of a non-woven material or a fibrous material.

4. The fastening assembly of claim 1, wherein the magnetic substance is substantially evenly distributed in the second protective layer.

5. The fastening assembly of claim 1, wherein the magnetic substance is substantially evenly distributed on a surface of the second protective layer that faces the first strip.

6. The fastening assembly of claim 1, wherein the magnetic substance is a ferromagnetic powder.

7. The fastening assembly of claim 1, wherein the first protective layer is made of polyurethane.

8. The fastening assembly of claim 1, wherein the first protective layer is formed by printing polyurethane on the first strip.

9. The fastening assembly of claim 1, wherein the second protective layer is made of paper.

10. The fastening assembly of claim 1, further comprising a magnetic layer interposed between the first strip and the second strip and comprising the magnetic substance.

11. A cushion having a fastening assembly, comprising a foam cushion body and at least a fastening assembly, the foam cushion body being co-molded with the fastening assembly into one piece, the cushion being characterized in that the fastening assembly comprises:

a first strip having a first surface and a second surface, the first surface being protrudingly provided with a plurality of hooks;

a first protective layer comprising a magnetic substance and provided lengthwise along two lateral sides of the first surface of the first strip so as to form sidewalls respectively and embed some of the hooks;

a second protective layer comprising the magnetic substance, wherein the second protective layer is attached to the first protective layer so as to cover the hooks of the first surface; and

a second strip attached to the second surface of the first strip, wherein the foam cushion body is engaged with the second strip of the fastening assembly.

12. The cushion having the fastening assembly of claim 11, wherein the foam cushion body further has at least a groove for accommodating the fastening assembly.

13. The cushion having the fastening assembly of claim 11, wherein the second protective layer has a surface facing the first strip and provided with a plurality of fastening structures for engaging with the hooks.

14. The cushion having the fastening assembly of claim 11, wherein the second strip is made of a non-woven material or a fibrous material.

15. The cushion having the fastening assembly of claim 11, wherein the magnetic substance is substantially evenly distributed in the second protective layer.

16. The cushion having the fastening assembly of claim 11, wherein the magnetic substance is substantially evenly distributed on a surface of the second protective layer that faces the first strip.

17. The cushion having the fastening assembly of claim 11, wherein the magnetic substance is a ferromagnetic powder.

18. The cushion having the fastening assembly of claim 11, wherein the first protective layer is made of polyurethane.

19. The cushion having the fastening assembly of claim 11, wherein the first protective layer is formed by printing polyurethane on the first strip.
