Abstract:
Protective reinforcement (3) for a tire has mean radial thickness T at least equal to two times diameter D of reinforcer (4), and comprises respectively on its radially interior face (31) and on its radially exterior face (32) parts (7) made of elastomeric compound having axial width W at least equal to diameter D of reinforcer (4). The path of any reinforcer (4), in circumferential direction (XX′), varies radially between radially interior first face (31) and radially exterior second face (32), in such a way that the set of paths of reinforcers (4) of protective reinforcement (3) constitutes a three-dimensional lattice. Furthermore, protective reinforcement (3) comprises a first family of reinforcers (41) each having a path, in the circumferential direction (XX), contained in circumferential plane (XZ) and a second family of reinforcers (42) each having a path, in the circumferential direction (XX′), that follows a zigzag curve.
