Vorrichtung zur Verhinderung von Reifenpannen

摘要

An anti-flat device for a tubeless pneumatic tire comprising an expandable toroidal air pressure reservoir or small inner tube restrained by a folded and stitched fabric band to prevent the inner tube from filling the tire even though the inner tube is inflated to a higher pressure than that normally employed for the tire. When the air pressure in the tire is reduced below a predetermined value, the band unfolds thereby permitting the inner tube to expand and provide operable support for the tire.
