PARTITION MEMBRANE FOR SAFETY TIRE, SAFETY TIRE, AND ASSEMBLY OF SAFETY TIRE AND RIM

摘要

PPROBLEM TO BE SOLVED: To provide a partition membrane for a safety tire, the safety tire, and an assembly of the safety tire and a rim, whose structure is comparatively simple and capable of efficiently letting out air filled inside the safety tire in spite of a conventional rim being usable. PSOLUTION: This partition membrane 1 for the safety tire is an expandable and deformable annular partition membrane 1 for safety tire that is arranged inside a conventional pneumatic tire 7 to constitute the safety tire 9. The partition membrane 1 for the safety tire divides a space partitioned by the tire 7 and a rim 10 into two chambers 14, 13 in an attached state that the tire 7 is attached to the rim 10; the two chambers being an outside chamber 14, partitioned by the outside surface of the partition membrane 1 for the safety tire and the tire inside surface, and an inside chamber 13, partitioned by the inside surface of the partition membrane 1 for the safety tire and the outside surface of the rim 10. Furthermore, the partition membrane 1 for the safety tire has two or more communication portions 16a, 16b, which, arranged with an interval from each other, can communicate the inside chamber 13 with the outside chamber 14.
