Abstract

Aspects herein provide for an apparel item having an integrated parachute structure and a set of intake ducts. The parachute structure is configured to transition from a first slack state to a second inflated state subsequent to air entering the set of intake ducts incident to ground locomotion of the wearer thereby increasing air resistance to wearer movement.

First claim

What is claimed is:

1. An apparel item comprising:
at least a front panel and a back panel, wherein:
the front panel comprises a first plurality of intake ducts, wherein the first plurality of intake ducts comprise flaps created in a material used to form the front panel, wherein the front panel has a thickness and the first plurality of intake ducts are substantially S-shaped openings formed through the thickness of the front panel, creating the flaps of the first plurality of intake ducts, wherein each of the S-shaped openings is divided into two halves by a strip of material left at a mid-point between the two halves, wherein the strip of material serves as a hinge point for the flaps of the first plurality of intake ducts; and
the back panel is configured to transition from a first slack state to a second inflated state subsequent to air entering the first plurality of intake ducts, wherein the second inflated state increases air resistance to ground locomotion of a wearer.

2. The apparel item of claim 1 , wherein the S-shaped openings are positioned in varying orientations on the front panel, such that different ones of the flaps are engaged by different wind flow patterns.

3. The apparel item of claim 1 , wherein the first plurality of intake ducts are in fluid communication with a space between an inner-facing surface of the apparel item and a wearer's body when the apparel item is in an as-worn configuration.

4. The apparel item of claim 1 , wherein at least one of a material used to form the back panel and the material used to form the front panel is substantially impervious to air.

5. The apparel item of claim 1 , further comprising a plurality of reinforcement strips on the back panel.

6. The apparel item of claim 5 , wherein the plurality of reinforcement strips are at least one of seam tape, a polyurethane tape, a thermoplastic polyurethane tape, memory wire, and fabric strips.

7. An apparel item comprising:
at least a front panel and a back panel that is at least partially attached to the front panel, wherein:
the front panel comprises a first plurality of intake ducts, wherein the first plurality of intake ducts comprise flaps created in a material used to form the front panel, wherein the front panel has a thickness and the first plurality of intake ducts are substantially S-shaped openings formed through the thickness of the front panel, creating the flaps of the first plurality of intake ducts, wherein each of the S-shaped openings is divided into two halves by a strip of material left at a mid-point between the two halves, wherein the strip of material serves as a hinge point for the flaps of the first plurality of intake ducts; and
the back panel is configured to transition from a first slack state to a second inflated state subsequent to air entering the first plurality of intake ducts, wherein the second inflated state increases air resistance to ground locomotion of a wearer.

8. The apparel item of claim 7 , wherein the first plurality of intake ducts are in fluid communication with a space between an inner-facing surface of the apparel item and a wearer's body when the apparel item is in an as-worn configuration.

9. The apparel item of claim 7 , wherein at least one of a material used to form the back panel and the material used to form the front panel is substantially impervious to air.

10. The apparel item of claim 7 , wherein the S-shaped openings are positioned in varying orientations on the front panel, such that different ones of the flaps are engaged by different wind flow patterns.

11. The apparel item of claim 7 , further comprising a plurality of reinforcement strips on the back panel, wherein the plurality of reinforcement strips are at least one of seam tape, a polyurethane tape, a thermoplastic polyurethane tape, memory wire, and fabric strips.

12. An apparel item comprising:
at least a front panel and a back panel that is at least partially attached to the front panel, wherein the apparel item is formed from a material that is substantially impervious to air, wherein:
the front panel has a thickness and a first plurality of intake ducts, wherein the first plurality of intake ducts are S-shaped openings formed through the thickness of the front panel, the S-shaped openings creating flaps in the front panel that are pivotal toward and away from the first plurality of intake ducts, wherein each of the S-shaped openings are divided into two halves by a strip of material left at a mid-point between the two halves, wherein the strip of material serves as a hinge point for the flaps;
wherein the first plurality of intake ducts are in fluid communication with a space between an inner-facing surface of the apparel item and a wearer's body when the apparel item is in an as-worn configuration; and
the back panel is configured to transition from a first slack state to a second inflated state subsequent to air entering the first plurality of intake ducts, wherein the second inflated state increases air resistance to ground locomotion of a wearer.

13. The apparel item of claim 12 , wherein the S-shaped openings are positioned in varying orientations on the front panel, such that different ones of the flaps are engaged by different wind flow patterns.

14. The apparel item of claim 12 , further comprising a plurality of reinforcement strips on the back panel, wherein the plurality of reinforcement strips are at least one of seam tape, a polyurethane tape, a thermoplastic polyurethane tape, memory wire, and fabric strips.
