ABSTRACT:
The present invention involves a ski boot closure system for ski boats equipped with a quick-closing lever and associated rack system.
This knuckle joint-type closing system for ski boots, brings the first and second boot flaps together, it includes at least one lever hinged to the first boot-flap and a traction component hinged to the second boot flap and to the lever, one of the lever's hinges being formed by a catch-pin freely engaged in a notch, the lever being capable of occupying an initial, closed position flap against the boot, a second, stable intermediate or partially-open position, and a third, fully-open position in which the catch-pin is disengaged from the notch. This system further comprises a mechanism for making the catch-pin automatically leave the notch when the opening lever movement is continued beyond the stable intermediate position, thereby separating the two boot-flaps.
