<p>The strap (31) has lugs on the edges and across them for automatic attachment on the tyre sides. The lugs take the form of bent levers (46) pivoted (47, 48) on the edge of the strap. One end comes against the tyre side and the other against the strap. The pressure to do this comes from the pressure of the strap around the tyre. Some of these levers are coupled in pairs, this can be using a sliding pivot (52). Locking is by a notched or toothed tongue.</p> |
