ABSTRACT:
A dynamic internal fitting system for a ski boot having a lower shell member and an upper cuff member. Interior of the ski boot there is provided a pair of strap members for engaging the lateral and dorsal aspects of a foot. One end of the strap members is attached to the sole of the ski boot. The opposite end of the strap members is connected to one end of a cable by means of a pivotable linking member. The cable extends from the linking member and is connected at its opposite end to a pulley. The pulley is releasably coupled to the cuff member and means are provided for manually selectively adjusting the length of the cable wrapped about the pulley. During skiing maneuvers, as the position of the foot changes in the boot, the linking member pivots for dynamically adjusting the tension applied to and the position of the strap members relative to the foot engaged thereby. Additionally, as the cuff member pivots relative to the shell member, the pulley rotates with the cuff member.
In another embodiment in a ski boot, there is provided a tongue member, a pair of cables extending from opposite lateral sides of the tongue member, and a pair of pulleys coupled to the opposite sides of an upper cuff member. Each of the cables is connected to a separate pulley. The pulleys are releasably coupled to the cuff member and rotate with the cuff member for dynamically adjusting the tension applied to and the position of the tongue member relative to the foot engaged thereby. In one embodiment, each of the pulleys is separately adjusted relative to the cuff member for adjusting the tension applied to and the position of the tongue member relative to the foot. In an alternative embodiment, both of the pulleys are connected to a common shaft and are adjusted together relative to the cuff member.
