Abstract: The invention is related to a ski boot having a pivoting front cuff including a rigid shell base on which is at least partially journaled an upper that includes a front cuff and a rear spoiler, the front cuff being pivotally mounted in the end zone of the shell base and covering a longitudinal slit provided in its upper front portion. On either side of the longitudinal slit of the front cuff are defined two transverse tongues that are joined together by at least one flexible traction element interposed between an anchoring element of one of the transverse tongues and a manoeuvering member affixed to the other transverse tongue so as to constitute an inner foot tightening device. According to the invention, the front portion of the front cuff includes slots adapted to allow its free sliding with respect to the corresponding spacers of the tongues so as to be applied permanently thereupon, regardless of the relative position of the tongues in accordance with the state of the inner foot tightening device.

Abstract: A safety binding for skis in which release of the boot from the ski is effected by a signal issuing from an electrical circuit. The electrical signal is a function of the force applied to a skier's leg, and is received in a circuit which compares the signal with different successive threshold levels, which are functions of different duration of application of the force. The release mechanism of the binding is operated if the value of this signal reaches, in an interval of time corresponding to a determined threshold level, the value of this level.
