Abstract
A tire rim of a motor vehicle includes a substantially cylindrical body for holding a tire, and a hub connected to the body through radial members, and has an outer face facing, in use, the outside of the vehicle, and an opposite inner face. At least one elongate flexible element associated with the rim can reach a resting configuration within the rim, and a working configuration, extended with respect to the resting configuration, of such a length as to allow the tire to be surrounded, in which each flexible element is wound around the tire to form a snow chain. The rim includes at least one retaining member at a zone of its inner face, to be engaged by a portion of a flexible element in its working configuration.
Claims18
A tire rim for a motor vehicle wheel which includes a substantially cylindrical body, and a hub connected to said body by radially extending members, which rim has an outer side facing away from the vehicle, and an inner side opposite to said outer side for supporting a tire,
- wherein said rim carries at least one traction member in the form of an elongate flexible element having a first end and a second end, which elongate flexible element is adapted to assume (A) a retracted configuration in which the elongate flexible element including both the first end and the second end are stowed within the rim, and (B) a working configuration in which the first end of the elongate flexible element remains stowed within the rim, while a part of the elongate flexible element is wound around the tire and the second end affixed to the inner side of the rim by at least one retaining member which is adapted to be engaged by the second end of said flexible element in its working configuration, wherein said elongated element reaches the said working configuration from its retracted configuration by pulling the elongate element from the rim against a returning action of an elastic spring.
