Clothing ventilation device allowing the human body to breathe
A ventilation device to be applied to items of clothing, which includes an assembly with through holes, which is composed of a band of material that is at least partially transparent and impermeable and is configured to be arranged externally. A layer is provided to be placed in view and is made of natural or synthetic fabric or natural or synthetic leather. At least one layer of adhesive polymeric material mutually joins the outer band and the layer, between which it is sandwiched. A membrane which is impermeable to water and permeable to vapor, provided to be arranged internally, is sealed at least perimetrically to the assembly on the side of the layer to be placed in view.
1. A ventilation device to be applied to items of clothing, comprising:
an outer band formed of a material that is at least partially transparent and impermeable,
a visible layer to be placed in view, and
at least one layer of adhesive polymeric material arranged between said outer band and said layer to join said outer band and said layer to form an assembly such that said layer is placed in view by said outer band that is at least partially transparent;
a membrane which is impermeable to water and permeable to vapor and sealed at least perimetrically to said assembly on a side of said layer opposite said outer band such that vapor may pass through said membrane toward said assembly and water may not pass through said membrane in a direction from said assembly; and
through holes extending through said outer band, said layer of adhesive polymeric material, and said layer placed in view by said outer band, wherein vapor passes from said membrane through said through holes.
2. The ventilation device according to claim 1 , wherein between said assembly and said membrane is arranged a layer of open-cell expanded plastic material.
3. The ventilation device according to claim 1 , wherein said layer of adhesive polymeric material is made of heat-sealing material.
4. The ventilation device according to claim 3 , wherein said layer of heat-sealing material has a thickness of approximately 0.1 mm.
5. The ventilation device according to claim 3 , wherein said outer band is made of PVC.
6. The ventilation device according to claim 1 , wherein said layer of adhesive polymeric material comprises a spread or coating of an adhesive configured to be reactivated by pressure or heat.
7. The ventilation device according to claim 1 , wherein a thermoformed element seals said membrane.
8. The ventilation device according to claim 1 , wherein said membrane is laminated together with a supporting layer.
9. The ventilation device according to claim 8 , wherein said supporting layer is a mesh.
10. The ventilation device according to claim 1 , wherein said membrane is laminated with at least one protective material.
11. A ventilation device applied to an item of clothing, comprising:
an outer band formed of a material that is at least partially transparent and impermeable,
a layer to be placed in view and being of the same type as said item of clothing on which said ventilation device is applied, and
at least one layer of adhesive polymeric material arranged between said outer band and said layer to join said outer band and said layer to form an assembly such that said layer is placed in view by said outer band that is at least partially transparent,
a membrane which is impermeable to water and permeable to vapor and scaled at least perimetrically to said assembly on a side of said layer opposite said outer band such that vapor may pass through said membrane toward said assembly and water may not pass through said membrane in a direction from said assembly; and
through holes extending through said outer band, said layer of adhesive polymeric material, and said layer placed in view by said outer band, wherein vapor passes from said membrane through said through holes.
