Abstract

A cushion cover for a ventilation seat includes: a first adhesive layer including an upper surface coupled to a lower surface of a cushion part of the ventilation seat, the lower surface of the cushion provided with an air flow channel; a non-permeable layer made of a non-permeable material and including an upper surface coupled to a lower surface of the first adhesive layer to block the air flow channel of the lower surface of the cushion part from outside; and a protective layer coupled to a lower surface of the non-permeable layer to direct friction between the non-permeable layer and a seat structure.

Claims

1. A cushion cover for a ventilation seat, the cushion cover comprising:

a first adhesive layer including an upper surface and a lower surface, the upper surface coupled to a lower surface of a cushion part of a ventilation seat, the lower surface of the cushion part provided with an air flow channel;

a non-permeable layer made of a non-permeable material and including an upper surface and a lower surface, wherein the upper surface of the non-permeable layer is coupled to the lower surface of the first adhesive layer and the air flow channel of the cushion part is sealed by the upper surface of the non-permeable layer such that air in the air flow channel is circulated in the air flow channel without escaping through the non-permeable layer;

a protective layer coupled to the lower surface of the non-permeable layer to prevent direct contact between the non-permeable layer and a seat structure; and

a second adhesive layer provided between the non-permeable layer and the protective layer and configured to couple the non-permeable layer and the protective layer together such that the non-permeable layer is compatible with and attached to any shapes of the lower surface of the cushion part.

2. The cushion cover of claim 1, wherein both the first adhesive layer and the second adhesive layer are in a form of a double sided adhesive tape.

3. The cushion cover of claim 2, wherein the first adhesive layer is made of a non-permeable adhesive, and the non-permeable adhesive is a liquid with fluidity so as to permeate through surface voids in the lower surface of the cushion part of the ventilation seat, such that the cushion part of the ventilation seat and the non-permeable layer are coupled together.

4. The cushion cover of claim 1, wherein both the first adhesive layer and the second adhesive layer are in a form of a non-permeable adhesive.

5. The cushion cover of claim 4, wherein the non-permeable adhesive is in a form of an acrylic pressure sensitive adhesive (PSA).

6. The cushion cover of claim 4, wherein the protective layer is made of a nonwoven fabric, and the non-permeable adhesive is a liquid with fluidity so as to permeate through surface voids in an upper surface of the nonwoven fabric layer, such that the non-permeable layer and the protective layer are coupled together.

7. The cushion cover of claim 1, wherein the non-permeable layer is made of at least one of an olefin based resin, a urethane based resin, a polyethylene terephthalate (PET) resin, or a polypropylene (PP) resin.

8. The cushion cover of claim 7, wherein the non-permeable layer is made of a material of the PP resin added with PP elastomer.

9. The cushion cover of claim 1, wherein the protective layer is of a nonwoven fabric.

10. The cushion cover of claim 1, wherein the protective layer is made of a nonwoven fabric, and the non-permeable layer is made of a thermoplastic resin film so as to permeate through surface voids in an upper surface of the nonwoven fabric layer, such that the non-permeable layer and the protective layer are thermally fused together.
