Abstract
Abstract A ski binding comprises a toe iron secured to a ski for receiving the toe portion of a boot and having inwardly turned upper edge portions for engaging the upper surface of the sole of the boot at the toe portion. The boot carries a forwardly extending engagement member which is automatically engaged with a fastening device solely upon insertion of the toe portion of the boot in the toe iron. The fastening device is constituted by a resilient spring blade which is attached at its rear end and extends forwardly so as to be gradually depressed and stressed by insertion of the toe portion of the boot in the toe iron. The spring blade carries a protrusion on the upper surface thereof which is adapted to engage with a bent front portion of the engagement member on the boot.
