ABSTRACT:
A small chain for a vehicle tire has an inner chain member adapted to lie along a flank of the tire and of a circumference substantially equal to the circumference of the tire in the region at which this inner chain member lies, the ends of the inner chain member having a hook and an eye for mutual engagement.
An outer chain is composed of two chain members which are interconnected by a hook and eye, the outer chain having a length in excess of the circumference of the tire in the region in which the outer chain lies thereagainst, the end of one member being formed with an eye and the end of the other member of the outer chain having an S-hook. The inner and outer chains are bridged by two sections of transverse chains linked to the inner and outer chains over the entire circumference of the tire. Each of the outer chain members is provided with a torsion-type spring whose legs are connected to the respective member at spaced apart locations and which are formed with central eyelets through which the longer outer chain member is threaded or anchored. A resilient insert is fitted into each of these eyelets.
