Abstract
Abstract This ski boot comprises a member for locking the upper in relation to the lower portion of the boot in the downhill running position, in the form of a rocker pivoted to a transverse axis in a cavity formed in the pivoted upper of the boot, and adapted to cooperate with a stop carried by the lower portion of the boot. The rocker can be released from the stop for straightening the skier's leg to a walking or non-skiing position by simply depressing the upper portion of the rocker. When the skier bends his leg the rocker is restored automatically to its locked position by a spring.

Total Claims: 10
Claim 1
Independent Claim
185 words
A ski boot comprising a boot lower, a boot upper pivotally mounted on the boot lower, a rocker pivotally mounted in a recess in the rear of the boot upper and adapted to be rotated between two positions, spring means urging rotation of said rocker on its pivot to the first of the two positions, a stop provided on the boot lower for engaging the rocker when it has been rotated to its first position, the rocker and stop cooperating to lock the boot upper against rearward movement of the boot lower when the boot upper is pivoted to a forward position, the rocker adapted to be manually urged against action of the spring means to the second position at which the stop is disengaged from the rocker, thereby unlocking the boot upper and permitting it to pivot rearwardly on the boot lower to facilitate standing and walking with the boot, and the rocker automatically being rotated to its first position by the spring means when the boot upper is pivoted forwardly in preparation for skiing to lock the boot upper in said forward position.
Claim 2
Dependent Claim
185 words
A ski boot comprising a boot lower, a boot upper pivotally mounted on the boot lower, a rocker pivotally mounted in a recess in the rear of the boot upper and adapted to be rotated between two positions, spring means urging rotation of said rocker on its pivot to the first of the two positions, a stop provided on the boot lower for engaging the rocker when it has been rotated to its first position, the rocker and stop cooperating to lock the boot upper against rearward movement of the boot lower when the boot upper is pivoted to a forward position, the rocker adapted to be manually urged against action of the spring means to the second position at which the stop is disengaged from the rocker, thereby unlocking the boot upper and permitting it to pivot rearwardly on the boot lower to facilitate standing and walking with the boot, and the rocker automatically being rotated to its first position by the spring means when the boot upper is pivoted forwardly in preparation for skiing to lock the boot upper in said forward position.
