Support interne pour s'opposer à l'applatissement d'un pneumatique

摘要

A support fastened to a wheel rim within a tire cavity to resist the flattening of the tire in the case of a blow-out is formed of an elastic radial support element arranged between the equatorial plane of the tire and the outside sidewall of the tire and of an elastic axial holding element arranged between the radial support element and the outside sidewall of the tire. A terminal annular protuberance of the axial holding element has a developed circumferential length greater than that of the periphery of the radial support element and is located axially towards the outside with respect to the connection of the axial holding element to the radial support element.
