  • Inner tube and method of producing such a tube
    Patent number: 8833416
    Abstract: An inner tube having a closed polymeric envelope with a primary surface comprising means allowing compression of the polymeric envelope when inflated under the normal conditions of use of the assembled unit. A radially outer part has a meridian curvature such that the ratio of the average radius of its meridian curvature to the radius of a circle of perimeter equal to the meridian perimeter of the primary surface of the polymeric envelope is greater than 2.5 and preferably greater than 10, when the inner tube is inflated to a pressure of 2000 pascals and the ratio of the average radius of the meridian curvature of the side parts to the radius of a circle of perimeter equal to the meridian perimeter of the primary surface of the polymeric envelope is greater than 2.5 and preferably greater than 10, when the inner tube is inflated to a pressure of 2000 pascals.
