Sole structure for article of footwear

Abstract

A sole structure for an article of footwear includes a bladder assembly having a first fluid-filled chamber spaced apart from a second fluid-filled chamber and a chassis. The chassis includes a plate. The plate has a bottom surface configured to accommodate the first fluid-filled chamber and the second fluid-filled chamber. The chassis further includes a shank configured to be seated to a mid-foot portion of the bottom surface of the plate and separate the first fluid-filled chamber from the second fluid filled chamber.

What is claimed is: 
     
         1 . A sole structure for an article of footwear, the sole structure comprising:
 a bladder assembly including a first fluid-filled chamber spaced apart from a second fluid-filled chamber; and   a chassis including a plate having a first portion in contact with the first fluid-filled chamber, a second portion in contact with the second fluid-filled chamber, and a third portion extending between and connecting the first portion and the second portion.   
     
     
         2 . The sole structure of  claim 1 , wherein the third portion spans a gap separating the first fluid-filled chamber from the second fluid-filled chamber. 
     
     
         3 . The sole structure of  claim 2 , wherein the chassis includes a first wing extending from the gap in a direction away from a ground-engaging surface of the sole structure. 
     
     
         4 . The sole structure of  claim 3 , wherein the chassis includes a second wing extending from the gap in a direction away from the ground-engaging surface of the sole structure. 
     
     
         5 . The sole structure of  claim 4 , wherein the first wing extends from one of a medial side of the sole structure and a lateral side of the sole structure and the second wing extends from the other of the medial side of the sole structure and the lateral side of the sole structure. 
     
     
         6 . The sole structure of  claim 1 , wherein the first fluid-filled chamber includes a central region defining an interior void receiving a fluid, the first portion of the plate including an aperture that receives the central region therein. 
     
     
         7 . The sole structure of  claim 6 , wherein the first fluid-filled chamber is disposed in a heel region of the sole structure. 
     
     
         8 . The sole structure of  claim 1 , wherein the second portion of the plate includes a medial leg and a lateral leg spaced apart from the medial leg across a width of the second portion. 
     
     
         9 . The sole structure of  claim 8 , wherein the medial leg and the lateral leg extend onto the second fluid-filled chamber in a direction away from a heel region of the sole structure. 
     
     
         10 . An article of footwear incorporating the sole structure of  claim 1 . 
     
     
         11 . A sole structure for an article of footwear, the sole structure comprising:
 an outsole defining a ground-engaging surface of the sole structure;   a chassis spaced apart from the outsole to define a void therebetween, the chassis including a plate having a first portion, a second portion, and a third portion extending between and connecting the first portion and the second portion; and   a bladder assembly disposed within the void and including a first fluid-filled chamber and a second fluid-filled chamber spaced apart from the first fluid-filled chamber by a gap.   
     
     
         12 . The sole structure of  claim 11 , wherein the third portion of the plate spans the gap. 
     
     
         13 . The sole structure of  claim 11 , wherein the chassis includes a first wing extending from the gap in a direction away from the ground-engaging surface of the sole structure. 
     
     
         14 . The sole structure of  claim 13 , wherein the chassis includes a second wing extending from the gap in a direction away from the ground-engaging surface of the sole structure. 
     
     
         15 . The sole structure of  claim 14 , wherein the first wing extends from one of a medial side of the sole structure and a lateral side of the sole structure and the second wing extends from the other of the medial side of the sole structure and the lateral side of the sole structure. 
     
     
         16 . The sole structure of  claim 11 , wherein the first fluid-filled chamber includes a central region defining an interior void receiving a fluid, the first portion of the plate including an aperture that receives the central region therein. 
     
     
         17 . The sole structure of  claim 16 , wherein the first fluid-filled chamber is disposed in a heel region of the sole structure. 
     
     
         18 . The sole structure of  claim 11 , wherein the second portion of the plate includes a medial leg and a lateral leg spaced apart from the medial leg across a width of the second portion. 
     
     
         19 . The sole structure of  claim 18 , wherein the medial leg and the lateral leg are disposed on an opposite side of the second fluid-filled chamber than the outsole and extend onto the second fluid-filled chamber in a direction away from a heel region of the sole structure. 
     
     
         20 . An article of footwear incorporating the sole structure of  claim 12 .
