A fluid-filled bladder (30) with a reinforcing structure (40) and a method of manufacturing the bladder and reinforcing structure are disclosed. In general, the reinforcing structure extends around the bladder, and the reinforcing structure is bonded to an exterior of the bladder. In some embodiments, the reinforcing structure is recessed into the bladder and extends along side surfaces of the bladder and between upper and lower surfaces of bladder. In manufacturing, the reinforcing structure may be located within a mold, and the polymer material forming the bladder may be bonded to the reinforcing structure during the molding process.
L'invention concerne une vessie remplie de fluide, à structure de renforcement et un procédé permettant de produire ladite vessie et la structure de renforcement. De manière générale, la structure de renforcement s'étend autour de la vessie et est liée à une zone extérieure de la vessie. Dans certains modes de réalisation, la structure de renforcement est en retrait dans la vessie et s'étend le long de surfaces latérales de ladite vessie et entre des surfaces supérieures et inférieures de la vessie. Au moment de la fabrication, la structure de renforcement peut être située à l'intérieur d'un moule et un matériau polymère formant la vessie peut être lié à la structure de renforcement pendant le processus de moulage.
