Abstract

Ventilated suit embodiments are disclosed. The ventilated suit typically comprises a hood portion, four limb portions, an air inlet port, and an air distribution system in fluid communication with the air inlet port and attached to the back portion of the ventilated suit. The air distribution systems comprises at least five air pathways that extend into the four limbs and hood of the suit, with the air pathways being in fluid communication with the air inlet port to distribute air outward into the limbs and hood.

First claim

What is claimed is:

1. A ventilated suit comprising:
a hood portion;
four limb portions;
an air inlet port; and
an air distribution system in fluid communication with the air inlet port and the air distribution system attached to the back portion of the ventilated suit, the air distribution system comprising:
at least five air pathways extending into the four limbs and hood of the suit, each of the air pathways in fluid communication with the air inlet port and configured to distribute air from the air inlet port out into corresponding one of the four limbs and hood of the suit; and
attachment points between the air pathways and the fabric of the back of the suit.

2. The suit of claim 1 , wherein the air distribution system comprises a central portion in fluid communication with the air inlet port and all of the at least five air pathways, configured such that air from the air inlet port flows into the central portion and then into the at least five air pathways.

3. The suit of claim 1 , wherein the ventilated suit is formed of one of an air impenetrable fabric, an air impenetrable plastic, or a breathable fabric.

4. The suit of claim 3 , wherein the air pathways comprise layers of fabric and the attachment points comprise stitches between the fabric of the air pathways and the fabric of the suit.

5. The suit of claim 4 , wherein at least one layer of the fabric of the air pathways and the fabric of the suit comprise being at least one of an air impenetrable fabric and a nonwoven fabric.

6. The suit of claim 4 , wherein the fabric of the suit comprises one of the layers that form the air pathways.

7. The suit of claim 3 wherein the air distribution system comprise hoses and the attachment points comprise loops stitched into the fabric of the suit.

8. The suit of claim 7 , wherein the air distribution system further comprises an air inlet pouch, fluidly connected to the air inlet port and the at least five hoses.

9. The suit of claim 7 , wherein the hoses comprise a flexible plastic material.

10. A ventilated suit comprising:
a hood portion;
four limb portions, comprising arm portions and leg portions;
an air inlet port; and
an air distribution system in fluid communication with the air inlet port and the air distribution system attached to the back portion of the ventilated suit, the air distribution system comprising:
at least five air pathways formed between layers of fabric extending into the four limbs and hood of the suit, each of the air pathways in fluid communication with the air inlet port and configured to distribute air from the air inlet port out into corresponding one of the four limbs and hood of the suit,
wherein:
the ventilated suit is formed of an air impenetrable fabric;
the at least five air pathways comprise the layers of fabric; and
the air pathways are formed by stitches between the at least a layer of fabric and the fabric of the suit.

11. The suit of claim 10 , wherein the fabric of the suit comprises one of the layers that form the air pathways.

12. The suit of claim 10 , wherein at least one layer of the fabric of the air pathways and the fabric of the suit comprise being at least one of an air impenetrable fabric and a nonwoven fabric.

13. The suit of claim 10 , wherein the stitches form ports at each end of each of the air pathways, and the ports allow air from the air inlet port to flow into corresponding air pathway and out of the air pathways into the suit.

14. The suit of claim 10 , wherein the at least five air pathways comprise a first pathway extending into the hood portion of the suit, a second pathway extending into an arm portion of the suit, a third pathway extending into an arm portion of the suit, a fourth pathway extending into a leg portion of the suit, and a fifth pathway extending into a leg portion of the suit.

15. The suit of claim 14 , wherein the first pathway comprises two sections that extend around either side of the hood portion of the suit.

16. A ventilated suit comprising:
a hood portion;
four limb portions, comprising arm portions and leg portions;
an air inlet port; and
an air distribution system in fluid communication with the air inlet port and the air distribution system attached to the back portion of the ventilated suit, the air distribution system comprising:
a central portion in fluid communication with the air inlet port;
at least five air pathways formed between layers of fabric extending into the four limbs and hood of the suit, each of the air pathways in fluid communication with the air inlet port via the central portion and configured to distribute air from the air inlet port out into corresponding one of the four limbs and hood of the suit; and
attachment points between the air pathways and the fabric of the back of the suit,
wherein:
the ventilated suit is formed of an air impenetrable fabric; and
the air pathways comprise hoses.

17. The suit of claim 16 , wherein the attachment points comprise loops sewn into the fabric of the suit.

18. The suit of claim 16 , wherein the at least five air pathways comprise a first pathway extending into the hood portion of the suit, a second pathway extending into an arm portion of the suit, a third pathway extending into an arm portion of the suit, a fourth pathway extending into a leg portion of the suit, and a fifth pathway extending into a leg portion of the suit.

19. The suit of claim 16 , wherein the central portion comprises a central air inlet pouch in fluid communication with the air inlet port and all of the at least five air pathways.

20. The suit of claim 16 , wherein the suit comprises a disposable suit operable to be worn once by a user.
