A fluid-filled bladder (40) for an article of footwear is disclosed that includes a sealed outer barrier (50) and a tensile member (60). The barrier is substantially impermeable to a fluid contained by the bladder, and the tensile member is located within the barrier and bonded to opposite sides of the barrier. The tensile member (60) defines a flexion area (65) that promotes flexing of a first portion (64a) of the bladder with respect to a second portion (63b) of the bladder. The flexion area is an area where the tensile member is absent, and the flexion area may have the configuration of a space, aperture, or indentation, for example.
L'invention concerne une enveloppe (40) remplie de fluide et destinée à un article chaussant, qui comprend une barrière (50) extérieure hermétiquement fermée et un élément (60) de tension. La barrière est sensiblement imperméable au fluide contenu dans l'enveloppe, et l'élément de tension, qui se situe dans la barrière, est lié à des côtés opposés de la barrière. L'élément de tension (60) définit une zone de flexion (65) qui facilite la flexion d'une première partie (64a) de l'enveloppe par rapport à une deuxième partie (63b) de celle-ci. L'élément de tension est absent dans la zone de flexion, cette zone pouvant prendre la forme d'un espace, d'une ouverture ou d'une échancrure, par exemple.
