Abstract
A fluid-filled chamber, which may be incorporated into articles of footwear and other products, may include an outer barrier and a tensile element. The outer barrier may have a first portion, an opposite second portion, and an interior surface defining an interior void. The tensile element may be secured to the first portion of the outer barrier in a plurality of first bond areas and may be secured to the second portion of the outer barrier in a plurality of second bond areas. Each of the bond areas may be connected to portions of the tensile element spaced from the interior surface.
Claims13
A fluid-filled chamber comprising:
- a first barrier portion including a first surface;
- a second barrier portion including a second surface that opposes the first surface, the second barrier portion joined to the first barrier portion to form a chamber defining an interior void between the first surface and the second surface;
- a tensile element disposed within the interior void and formed from a sheet of material having a first side and a second side disposed on an opposite side of the sheet of material than the first side, the sheet of material being secured to the first surface of the first barrier portion at a plurality of first bond areas and being secured to the second surface of the second barrier portion at a plurality of second bond areas to define a plurality of frustoconical structures that taper in a direction between the first barrier portion and the second barrier portion, the tensile element including a plurality of apertures extending between the plurality of first bond areas and the plurality of second bond areas, one or more of the first bond areas being larger than other of the first bond areas and alternating with the other of the first bond areas in a first direction extending substantially perpendicular to a longitudinal axis of the fluid-filled chamber to form rows of first bond areas and one or more of the second bond areas being larger than other of the second bond areas and alternating with the other of the second bond areas in the first direction to form rows of second bond areas that are offset from the rows of first bond areas in a second direction extending substantially parallel to the longitudinal axis;
- a first bond inhibitor disposed on the first surface of the first barrier portion between the first barrier portion and the tensile element, the first bond inhibitor being formed from a sheet of material and including a plurality of first apertures formed therethrough at the first bond areas;
- and
- a second bond inhibitor disposed on the second surface of the second barrier portion between the second barrier portion and the tensile element, the second bond inhibitor being formed from a sheet of material and including a plurality of second apertures formed therethrough at the second bond areas.
