Abstract

Footwear upper components include a fabric element and a bladder component that defines a sealed interior chamber. The bladder component includes: (a) a first major surface engaged with the fabric element, wherein this first major surface defines at least part of a first perimeter seam surface and at least part of a first surface of the sealed interior chamber, (b) a second major surface opposite the first major surface, wherein this second major surface defines at least part of a second perimeter seam surface opposite the first perimeter seam surface and at least part of a second surface of the sealed interior chamber opposite the sealed interior chamber's first surface, and (c) and a fluid chamber between the first and second major surfaces. The first major surface (and optionally the second major surface) may include texturing, e.g., texturing corresponding to texture present on a surface of the fabric element.

First claim

What is claimed is:

1 . A footwear upper component, comprising:
a first fabric element that includes a first surface having texturing, wherein the first surface has a mesh structure with openings defined within a matrix formed by the first fabric element; and a bladder component that defines a sealed interior chamber for containing a fluid, wherein the bladder component includes: (a) a first major surface engaged with the first surface of the first fabric element, wherein the first major surface defines at least part of a first perimeter seam surface and at least part of a first surface of the sealed interior chamber, (b) a second major surface opposite the first major surface, wherein the second major surface defines at least part of a second perimeter seam surface opposite the first perimeter seam surface and at least part of a second surface of the sealed interior chamber opposite the first surface of the sealed interior chamber, and (c) and a fluid chamber located between the first major surface and the second major surface, wherein at least a portion of the first major surface includes texturing having surface contour features corresponding to the texturing present on the first surface of the first fabric element, and wherein the mesh structure and openings of the first surface of the first fabric element produce the surface contour features on the first major surface of the bladder component.

2 . The footwear upper component according to claim 1 , wherein the texturing on the first major surface of the bladder component includes texturing on the first surface of the sealed interior chamber.

3 . The footwear upper component according to claim 1 , wherein the texturing on the first major surface of the bladder component includes texturing on the first perimeter seam surface.

4 . The footwear upper component according to claim 1 , wherein at least a portion of the second major surface includes texturing corresponding to the texturing present on the first surface of the first fabric element.

5 . The footwear upper component according to claim 4 , wherein the texturing on the second major surface of the bladder component includes texturing on the second surface of the sealed interior chamber.

6 . The footwear upper component according to claim 1 , wherein the first major surface of the bladder component is formed from a first thermoplastic sheet and the second major surface of the bladder component is formed from a second thermoplastic sheet, and wherein the second thermoplastic sheet is formed from an at least partially transparent or translucent material such that the texturing present on at least a portion of the first major surface is visible through the second thermoplastic sheet.

7 . A footwear upper component, comprising:
a first fabric element that includes a first surface having texturing, wherein the first surface has a mesh structure with openings defined within a matrix formed by the first fabric element; and a bladder component that defines a sealed interior chamber for containing a fluid, wherein the bladder component includes: (a) a first major surface engaged with the first fabric element, wherein the first major surface defines at least part of a first perimeter seam surface and at least part of a first surface of the sealed interior chamber, (b) a second major surface opposite the first major surface, wherein the second major surface defines at least part of a second perimeter seam surface opposite the first perimeter seam surface and at least part of a second surface of the sealed interior chamber opposite the first surface of the sealed interior chamber, and (c) and a fluid chamber located between the first major surface and the second major surface, wherein at least a portion of the second major surface includes molded-in texturing, and wherein the mesh structure and openings of the first surface of the first fabric element produce the molded-in texturing on the second major surface of the bladder component.

8 . The footwear upper component according to claim 7 , wherein the molded-in texturing on the second major surface of the bladder component includes texturing on at least a portion of the second surface of the sealed interior chamber.

9 . The footwear upper component according to claim 7 , wherein the molded-in texturing includes at least one member selected from the group consisting of: a plurality of raised grid elements; a plurality of recessed grid elements; and a first portion having a first pattern and a second portion having a second pattern different from the first pattern.

10 . The footwear upper component according to claim 7 , wherein the molded-in texturing on the second major surface of the bladder component includes texturing on the second perimeter seam surface.

11 . The footwear upper component according to claim 7 , wherein the first major surface of the bladder component is formed from a first thermoplastic sheet and the second major surface of the bladder component is formed from a second thermoplastic sheet.

12 . The footwear upper component according to claim 7 , wherein the first fabric element is a knit fabric element.

13 . The footwear upper component according to claim 7 , wherein the first major surface of the bladder component is engaged with the first fabric element by an adhesive free bond.

14 . The footwear upper component according to claim 7 , wherein the second major surface of the bladder component is exposed at an exterior of the footwear upper component.

15 . The footwear upper component according to claim 7 , wherein at least a portion of the first major surface includes texturing having surface contour features corresponding to the texturing present on the first surface of the first fabric element, wherein the second major surface of the bladder component is formed from a thermoplastic sheet, and wherein the thermoplastic sheet is formed from an at least partially transparent or translucent material such that the texturing present on at least a portion of the first major surface is visible through the thermoplastic sheet.

16 . The footwear upper component according to claim 4 , wherein the texturing on the second major surface of the bladder component includes texturing on the second perimeter seam surface.

17 . The footwear upper component according to claim 1 , wherein the first fabric element is a knit fabric element.

18 . The footwear upper component according to claim 1 , wherein the first major surface of the bladder component is engaged with the first fabric element by an adhesive free bond.

19 . The footwear upper component according to claim 4 , wherein the second major surface of the bladder component is exposed at an exterior of the footwear upper component.

20 . The footwear upper component according to claim 1 , wherein the second major surface of the bladder component is formed from a thermoplastic sheet, and wherein the thermoplastic sheet is formed from an at least partially transparent or translucent material such that the texturing present on at least a portion of the first major surface is visible through the thermoplastic sheet.
