Embodiment Construction

[0043] The following discussion and figures disclose various fluid-filled cavities and methods of making the same. Although the cavity is discussed in terms of its application in footwear, the cavity can also be incorporated into a variety of other products including, for example, straps for carrying backpacks and golf bags, cushioning or for football or hockey helmets, or bicycle saddles. Additionally, the cavity can be incorporated into various non-sports products, such as inflatable mattresses and seat cushions. Accordingly, the various fluid-filled cavities disclosed below with respect to footwear may be used with various products.

[0044] figure 1An article of footwear 10 including an upper 20 and a sole structure 30 is shown. Upper 20 is of substantially conventional construction and includes various components, such as textile, foam, and leather materials, that are stitched or bonded together to form an interior volume for securely and comfortably receiving the foot...

Abstract

A fluid-filled chamber (40) may include an outer barrier (51, 52) formed from a polymer material and a foam tensile member (60) located within the outer barrier. In manufacturing the fluid-filled chamber, a mold may be contoured to substantially equalize compressive forces between the outer barrier and various portions of the tensile member, thereby providing substantially uniform bonding betweenthe outer barrier and the tensile member. Surfaces of the tensile member may also be contoured to substantially equalize compressive forces. In some configurations, the outer barrier and tensile member may be formed from thermoplastic polymer materials that form a direct bond between the outer barrier and surfaces of tensile member.

Description

Background technique [0001] A conventional article of athletic footwear consists of two main components - an upper and a sole structure. The upper, which can be made from a variety of material compositions (eg, textiles, leather, and foam), defines a void to securely receive and secure the foot relative to the sole structure. The sole structure is secured to the lower surface of the upper and is generally positioned to extend between the foot and the ground. In addition to attenuating ground reaction forces, the sole structure provides traction and controls various foot movements, such as pronation. Accordingly, the upper and sole structure work cooperatively to provide a comfortable structure for various ambulatory activities, such as walking and running. [0002] The sole structure of the article of athletic footwear generally represents a layered configuration including an insole for increased comfort, a resilient midsole formed at least in part from polymer foam, and A ...
