Abstract
A device for fastening a boot to a cross-country ski including a stirrup having a central part articulated on a pin transverse to the ski, and branches shaped to allow fitting of a complementary part made at the front end of the boot. The stirrup is equipped with structure for immobilizing the front end of the boot, which consist of a locking lever mounted to pivot on the stirrup around a pin transverse to the ski, a catch mounted to pivot on the locking lever around a pin crosswise to the ski, comprising two fingers coming in contact with the front edges of the stirrup forming control ramps of the position of the lever, and an elastic element placed between the stirrup and the lever and acting on the latter in the closing direction, in a plane passing approximately through the pin for articulation of the catch on the lever and on both sides of which are points of contact between the catch and stirrup, respectively in an opening position and in a closing position.
