Abstract

This invention relates to undergarments for use in active environments, where the wearer of such an undergarment is engaged in an activity that results in accelerating movements. In some preferred embodiments, these undergarments may be athletic or sports bras that redirect momentum related to a wearer's accelerating movements, for example, during exercise.

First claim

What is claimed is:

1. A pressure-distributing reinforcing structure for an article of apparel comprising:
a chest band configured to be positioned around a top portion of a wearer's breast tissue and configured to anchor a root of the breast tissue;
an upper base band configured to provide support around an underside of the root of the wearer's breast tissue, wherein a part of the upper base band forming a side wing that is configured to support a side portion of the root of the wearer's breast tissue;
a lower base band; and
a pair of straps,
wherein the chest band, the upper base band, and the side wing are configured to support breast tissue directly around a root of the breast tissue in a first amount of support in order to control accelerating movements of the wearer's breast tissue,
wherein the first amount of support is different than a second amount of support provided by the lower base band, and
wherein each of the pair of straps includes an outer shoulder strap and an inner shoulder strap, the outer shoulder strap and the inner shoulder strap having different pressure modulus values attributable to structural properties of materials comprising the outer shoulder strap in comparison to structural properties of materials comprising the inner shoulder strap.

2. The pressure-distributing reinforcing structure according to claim 1 , wherein at least a portion of the structure is constructed using three-dimensional knitting.

3. The pressure-distributing reinforcing structure according to claim 1 , wherein the chest band includes an upper chest band and a lower chest band, the upper chest band and the lower chest band having different pressure modulus values attributable to differences in the structural properties of materials comprising the upper chest band in comparison to structural properties of materials comprising the lower chest band.

4. The pressure-distributing reinforcing structure according to claim 1 , wherein the pressure distributing reinforcing structure comprises an intermediate layer in the article of apparel.

5. The pressure-distributing reinforcing structure according to claim 1 , wherein the pressure reinforcing structure is further configured to be layered within the article of apparel.

6. A system configured to manage accelerating movements of breast tissue comprising:
a reinforcing structure constructed with materials of varying moduli, wherein a material with highest modulus values are configured to be positioned adjacent to a root of the breast tissue
wherein the reinforcing structure includes a chest band configured to be positioned around a top of a wearer's breast tissue in order to anchor a root of the breast tissue, an upper base band configured to provide support around an underside of the root of the wearer's breast tissue, a part of the upper base band forming a side wing configured to support a side of the root of the wearer's breast tissue, a lower base band and a pair of straps,
wherein the chest band, the upper base band and the side wing are configured to support breast tissue directly around a root of the breast tissue in a first amount to control accelerating movements of the wearer breast tissue,
wherein the first amount of support is different than a second amount of support provided by the lower base band of the reinforcing structure, and
wherein each of the pair of straps includes an outer shoulder strap and an inner shoulder strap, the outer shoulder strap and the inner shoulder strap having different pressure modulus values attributable to structural properties of materials comprising the outer shoulder strap in comparison to structural properties of materials comprising the inner shoulder strap.

7. The system of claim 6 , wherein the reinforcing structure is coupled with at least one additional layer of material having substantially uniform modulus.

8. The system of claim 6 , wherein at least a portion of the reinforcing structure is constructed using three-dimensional knitting.

9. The system of claim 6 , wherein the reinforcing structure is configured to be an intermediate layer in an article of apparel.

10. A method for providing pressure-distributing reinforcement in an article of apparel comprising:
positioning a chest band around a top portion of a wearer's breast tissue in order to anchor a root of the breast tissue;
positioning an upper base band around an underside of the root of the wearer's breast tissue, wherein a part of the upper base band forms a side wing that supports a side portion of the root of the wearer's breast tissue;
positioning the chest band, the upper base band, and the side wing in order to support breast tissue directly around a root of the breast tissue in a first amount of support in order to control accelerating movements of the wearer's breast tissue,
wherein the first amount of support is different than a second amount of support provided by a lower base band.

11. The method of claim 10 , further comprising providing a pair of straps, wherein each of the pair of straps includes an outer shoulder strap and an inner shoulder strap, the outer shoulder strap and the inner shoulder strap having different pressure modulus values attributable to structural properties of materials comprising the outer shoulder strap in comparison to structural properties of materials comprising the inner shoulder strap.

12. The method of claim 10 , wherein the chest band, upper base band, and lower base band are provided as a layer within the article of apparel.

13. The method of claim 12 , wherein the layer is provided through three-dimensional knitting.
