Body Serving as a Support for a Tire in the Event of Deflation and Tire Assembly Equipped with such a Body

摘要

A body ( 30 ) designed to be placed inside a tire ( 10 ) so as to seal any puncture which a sidewall ( 12 ) of said tire may suffer while providing said tire with support. The body ( 30 ) comprises a flexible skin ( 31 ), of resilient elastomeric material, reinforced by a carcass reinforcement ( 311 ) anchored to two inextensible circumferential reinforcement structures ( 33 ) incorporated in said skin. The carcass reinforcement ( 311 ) is capable of withstanding the forces applied by an inflation pressure corresponding to the rated inflation pressure of the tire inside which the body ( 30 ) is placed. An assembly is disclosed formed of a tire ( 10 ) mounted on a rim ( 20 ) and equipped with such a body ( 30 ).
